また、ファイルｖｉｄｅｏ１→ｖｉｄｅｏ２→ｖｉｄｅｏ３の順に再生すると共に、ｖｉｄｅｏ１に対しては、音声データのファイルであるａｕｄｉｏ１をアフレコトラックとして同時再生させたいときには、

のようにして記述が行われることになる。
【００９７】
また、或るファイルと同期再生させるべきファイルについて、この或るファイルが再生されて何秒後の位置から再生させる等の指定を行うための記述も用意されている。
例えば、ｖｉｄｅｏ１の画像ファイルが表示（再生）されてから５秒後にキャプション（例えば文字情報としての画像）を表示させるような場合には、

のようにして記述が行われることになる。
【００９８】
また、例えば静止画ファイルとしてのファイルｐｉｃｔｕｒｅ１を５秒間表示するように指示するのであれば、
＜ｉｍａｇｅ ｓｒｃ＝”ｐｉｃｔｕｒｅ１” ｄｕｒ ＝ ”５ｓ”＞
のようにして記述される。
【００９９】
また、いわゆるフレームミュートといわれ、或る動画ファイルの一部を抜き出すようにして再生する場合には、「ｒａｎｇｅ」を利用する。例えば、タイムコードとしてＳＭＰＴＥ(Society of Motion Picture and Television)の規格を採用しているとして、
＜ｖｉｄｅｏ ｓｒｃ＝”ｖｉｄｅｏ１”ｒａｎｇｅ＝”ｓｍｐｔｅ：１０：０７：００−１０：０７：３３”＞
のようにして記述することができる。
【０１００】
また、或るファイルを指定してリピートを行うのには、「ｒｅｐｅａｔ」を利用する。例えばｖｉｄｅｏ１のファイルを１０回リピートするのであれば、
＜ｖｉｄｅｏ ｓｒｃ ＝ ”ｖｉｄｅｏ１”ｒｅｐｅａｔ ＝ ”１０”＞
のようにして記述する。
【０１０１】
そして本実施の形態においては、このような、ＳＭＩＬといわれるスクリプトを利用し、サムネイル表示として所要の表示形態を与えるための表示制御を実行可能に構成されるものである。
このため、例えば本実施の形態のビデオカメラシステムにおいては、このＳＭＩＬに対応した解釈、及びスクリプトの記述（生成）が行えるように、ＸＭＬのサブセットが用意されることになる。これは、例えばビデオコントローラ３８が実行すべきプログラムとして、ビデオコントローラ３８内のＲＯＭ等に予め格納したり、或いはディスクのアプリケーションレイヤーに対して記録して、読み出しが行えるようにしておけばよい。
【０１０２】
本実施の形態においては、このようなスクリプトは、例えば、編集段階（又は録画操作を行っている段階）において、ビデオコントローラ３８が生成又は更新を行って、例えばバッファメモリ３２内の所定領域に保持しておくものとされる。
そして、このようにしてバッファメモリ３２に保持されたスクリプトを、所定の機会、又はタイミングでもってディスクに記録するようにされる。このスクリプトのデータは、図７にて説明した補助データトラック(Auxiliary Data Track)に対して、スクリプトファイルとして格納されることになる。このようにしてディスクにスクリプトが記録されることで、次にこのディスクを新たに装填したときには、このディスクに記録されたスクリプトを読み出し、例えば、バッファメモリ３２に対して保持させてこれを参照することで、以前の編集により得られた再生順等に従って編集再生等を行うことが可能となるものである。
【０１０３】
８．本実施の形態の映像作品の作成機能
８−１．概要
続いて、本実施の形態の映像作品の作成機能（編集機能）について説明する。本実施の形態の映像作品の作成機能にあたっては、編集用のアプリケーションプログラム（入力指示プログラム及び編集プログラム）が用意される。この編集用のアプリケーションプログラムは、或る特定のジャンルの映像作品を編集するためのプログラムとされ、予め設定された脚本に従って映像作品を作成するようにされるものである。
具体的には、先ず映像作品の素材となるソース（録画ファイル）の撮影時において、上記脚本に基づいてガイド機能としてのＧＵＩを表示することで、ユーザに対して適宜、必要とされる入力操作及び撮影を促すようにされる。このＧＵＩに従って行われた入力操作により得られた情報（文字情報を含む）や、撮影により得られた録画ファイル（画像／音声データのファイル）が編集素材情報として扱われる。
そして、実際の編集処理としては、上記脚本構造に従って、上記編集素材情報を利用した編集を行うことで映像作品を作成するものである。但し、本実施の形態では、編集処理に際して、撮影された録画ファイルに直接編集処理を施すのではなく、前述したスクリプトにより録画ファイルの再生順、および各種編集効果（例えばスーパインポーズやＢＧＭの挿入）の指定が行われ、ビデオカメラでは、このスクリプトを解釈して適宜所要の信号処理を行うことで編集再生を行うものである。
【０１０４】
また、本実施の形態では、この編集用のアプリケーションプログラムは、ディスクに対して１つのファイル（トラック）として記録されているものとされる。そして、この編集用のアプリケーションプログラムのガイド機能によって録画されたファイルや、スクリプトファイルもこの同じディスクに記録されるものである。
つまり、本実施の形態では、或る特定の目的に従った映像作品のための編集用のアプリケーションプログラムをディスクに記録し、この編集に必要な素材としてのデータ、及びスクリプトを記録可能とすることで、この特定のジャンルの映像作品を作成して再生するために特化されたディスクを提供するものである。
なお、編集用のアプリケーションプログラムについては、例えばビデオカメラ側に不揮発性メモリを設け、この不揮発性メモリに対してこれを記憶させておくことも考えられる。つまり、ビデオカメラ自体が、或る特定のジャンルの映像作品を作成するための機能を備えるように構成することが考えられる。
【０１０５】
８−２．ガイド機能に従った情報入力及び撮影
そこで以降、本実施の形態における映像作品の作成の過程を、１つの具体例に沿って説明していくこととする。
ここでは、具体例としてゴルフコンペの模様を映像作品として作成する場合を例に挙げる。従って、この場合のユーザは、ゴルフコンペ用の編集用プログラムが記録されて、ゴルフコンペの映像作品作成用に特化されたディスクを用意することになる。
また、ここではＡさん、Ｂさん、Ｃさんの三人のユーザがゴルフコンペを行う場合を例に挙げることとする。以降、「ユーザ」といった場合には、Ａさん、Ｂさん、Ｃさんのうちの少なくとも何れかのうち当該ビデオカメラを扱う人を指すことになる。
【０１０６】
先ず、図８〜図１０により、ユーザがゴルフコンペを行いながら、編集のための情報入力（操作情報の入力、及び編集素材の撮影）を行う手順例について説明する。また、以降の説明においては、入力操作等に対応するプログラムを逐次必要に応じて示すが、このプログラムは、当該ビデオカメラのマスターコントローラ（ビデオコントローラ３８）がＪＡＶＡ言語を理解可能なシステムを搭載している構成対応している場合のプログラムとする。そこで、このプログラムにおける本例での変数定義及びクラス定義について、先に、ここに示しておく。

変数一覧
ｉｎｔ ｎｕｍｂｅｒｏｆｐａｒｔｙ；／／パーティの人数
Ｓｔｒｉｎｇ ｃｏｕｒｓｅ；／／コースの名前
Ｐａｒｔｙ ｐａｒｔｙ［］；／／パーティの人数分のメンバーの情報
Ｔｒａｃｋ ｔｒａｃｋ［］；／／自由に撮影したトラックの
Ｈｏｌｅ ｈｏｌｅ［］；／／このコースの情報（１８ホール）
【０１０７】
例えばユーザ（Ａさん、Ｂさん、Ｃさん）は、本実施の形態のビデオカメラ及び、ゴルフコンペ映像作品作成用に特化された本実施の形態のディスク（以降、単に「ゴルフ用ディスク」という）を携帯して目的のゴルフ場に赴くようにされる。
そして、例えばゴルフ場においてコースをラウンドする前の段階で、ビデオカメラにゴルフ用ディスクを装填し、所定操作によってディスクに記録されている編集用アプリケーションプログラムのガイド機能表示を動作させる。このための操作としては、例えば、通常のファイル再生のための所定の操作手順に従って編集用プログラムを選択して再生するようにされる。これにより、編集用プログラムが起動されることになり、例えば最初に編集用プログラムのメニュー画面が表示される。そして、ユーザはこのメニュー画面に対して操作を行って、ガイド機能表示を呼び出すようにされる。
【０１０８】
これにより、例えば表示部６Ａには、編集用プログラムに従って図８に示すガイド表示が行われていくことになる。なお、この図８に示されるガイド表示は、ラウンド前において編集に必要な各種情報を入力するためのものとされる。
【０１０９】
ここでは、ラウンド前の準備入力のためのガイド表示として、先ず図８（ａ）に示す表示が行われる。図８（ａ）のガイド表示は、コースをラウンドする人数を入力するためのものとされる。この場合には、３人であるので、ユーザはこＮ画面に対して３人であることを入力するための操作を行う。このときの操作手順としては、例えば「２人」「３人」「４人」「５人」のボタンと、「それ以上 人」の入力ウィンドが表示されているので、例えばユーザは、十字／クリックキー３１０を操作して「３人」のボタンにカーソル（図示せず）を配置させ、この状態で十字／クリックキー３１０のセンター部分に対するクリック操作を行う。つまり、「３人」のボタンを選択してクリック操作を行う。これにより、ラウンドする人数が３人であるという情報が入力される。この入力操作に応じたプログラムとしては、例えば
ｎｕｍｂｅｒｏｆｐａｒｔｙ＝３；
のようになる。
なお、以降においても示されるこのようなプログラムの記述は、後述するスクリプトの作成に利用されるために保存されておく必要があるが、例えば逐次、ディスクの所定のディレクトリに対して記録するように構成すればよい。或いは、ビデオカメラ内部のメモリ（例えばバッファメモリ４２など）の所定領域に格納して保持しておくようにすることも考えられる。
【０１１０】
図８（ａ）のガイド表示に対する入力操作が終了し、例えば「次へ」と表示されているボタンに対してクリック操作を行うと、図８（ｂ）に示すガイド表示に切り替わる。
図８（ｂ）のガイド表示は、メンバー一人一人が抱負を語っている場面の撮影を促すものである。例えばここでは、現在の撮像画像（現在レンズブロック１及びカメラブロック２により得られている画像信号である）が表示されている状態とされたうえで、「１人目の今日の抱負を５秒くらいで撮ってください」などのように、抱負を語るメンバーの撮影を促す文字表示（スーパインポーズ）と、被写体となるメンバーの構図を指定する「撮影指定枠」のインポーズ表示が行われる。この「撮影指定枠」は、変種素材としての被写体について理想的な構図を指定するために表示するものであり、実際の編集再生時には表示はされない（上記文字表示も同様である）。この表示が行われている表示部６Ａをモニタしながら、ユーザは、抱負を語る１メンバーの撮影を、そのメンバーが撮影指定枠にほぼちょうど収まるような構図で、５秒程度で行うようにされる。
ここで撮影された録画ファイル（動画像／音声ファイル）は、例えばｖｉｄｅｏ１とファイル名が付されてディスクに記録されることで保存されると共に、プログラムでは、
ｐａｒｔｙ［０］．ｂｅｇｉｎｃｏｍｍｅｎｔ＝ｖｉｄｅｏ１；
のような形式で１人目のラウンド前のコメントであるという関連付けを行う。
【０１１１】
ここでは、或る１メンバーの撮影が終了したとすると、ガイド表示として図８（ｃ）に示す表示が行われるものとされる。つまり、今撮影した映像がユーザにとって納得したものであるか否かが問われる。そして、この段階では、「見直す」のボタンに対するクリック操作で、今撮影した画像を再生してチェックすることができ、また、納得のいかない撮影結果だったのであれば、「取り直す」ボタンに対するクリック操作によって、再度、図８（ｂ）に示すガイド表示の状態での撮影を再開することができる。ここで、撮影した画像が結果的にユーザにとって納得のいくものであれば、所定操作により図８（ｃ）のガイド表示を抜けて、図８（ｄ）に示すガイド表示に移行させる。
【０１１２】
図８（ｄ）に示すガイド表示では、今撮影したメンバーに関する情報として、名前、ハンディなど、実際には予め入力項目として用意された項目に対して文字入力を行うことができるようになっている。本実施の形態では、図６に示したジョグダイヤル３１１を利用して文字入力を行うことができるようになっている。また、このガイド表示では、メンバーの顔写真が表示されているものとされる。この顔写真の画像は、先に抱負を語った場面を録画したファイルの画像データからサムネイル画像を生成することにより得られる。このような処理は、編集用プログラムにより、自動的に実行されるものとされる。
そして、必要な項目に対する文字入力が終了したら、例えば「ＯＫ」ボタンに対するクリック操作を行う。このとき、プログラムとしては、例えば一人目に撮影したメンバーについての文字入力が行われたのであれば、
ｐａｒｔｙ［０］．ｎａｍｅ＝″Ａさん″；
ｐａｒｔｙ［０］．ｈａｎｄｙｃａｐ＝２０；
のようにして、メンバーの名前、ハンディキャップが登録される。
【０１１３】
ここで、上記「ＯＫ」ボタンに対するクリック操作を行った場合に移行するガイド表示であるが、未だメンバー全員についての抱負を語る場面の撮影が完了していなければ、図８（ｂ）に戻るようにされる。この場合には、メンバーが３人なので、図８（ｂ）→図８（ｃ）→図８（ｄ）により説明した手順をユーザは３回繰り返すようにされる。このようにして、メンバー全員についての抱負を語る場面の撮影が完了した段階では、プログラムとして、
ｐａｒｔｙ［１］．ｂｅｇｉｎｃｏｍｍｅｎｔ＝ｖｉｄｅｏ２；
ｐａｒｔｙ［２］．ｂｅｇｉｎｃｏｍｍｅｎｔ＝ｖｉｄｅｏ３；
のようにして、２人目、３人目のメンバーの抱負を語った録画ファイルがｖｉｄｅｏ２、ｖｉｄｅｏ３として登録され、また、図８（ｄ）のガイド表示に対する２人目、３人目のメンバーについての文字入力により、
ｐａｒｔｙ［１］．ｎａｍｅ＝″Ｂさん″；
ｐａｒｔｙ［１］．ｈａｎｄｙｃａｐ＝８；
ｐａｒｔｙ［２］．ｎａｍｅ＝″Ｃさん″；
ｐａｒｔｙ［２］．ｈａｎｄｙｃａｐ＝１５；
のようにして関連付けが行われる。
【０１１４】
上記のようにして、図８（ｂ）→図８（ｃ）→図８（ｄ）により説明した手順がメンバー全員分繰り返された後、図８（ｄ）に示す「ＯＫ」ボタンが操作された場合には、図８（ｅ）のガイド表示に移行する。
【０１１５】
図８（ｅ）のガイド表示では、これよりラウンドするコース選択を行うようにされる。
このため、図８（ｅ）に示すガイド表示では、ゴルフ場のコースの候補が表示される。ここに候補として表示されるゴルフ場のコースは、編集用プログラム内にデータベースとして格納されているものとされ、このデータベースには、例えば各コースごとのホール数、ホールごとのヤード数（距離）、パー数等の情報が格納されている。
ユーザは、図８（ｅ）に示すガイド表示上で、例えば十字／クリックキー３１０を操作することで、これよりラウンドするゴルフ場のコースを選択してクリック操作（決定操作）を行う。ここでは、ゴルフ場のコースとして「柏カントリークラブ」を選択決定したものとする。
これにより、プログラムとしては、
ｃｏｕｒｓｅ＝″柏カントリークラブ″；
のようにして登録が行われることになる。
【０１１６】
前述したように、この編集用プログラムはコースのデーターベースを持っており、この場合であれば、上記のようにして柏カントリークラブが登録されたことで、柏カントリークラブの全ホールに対する全長、パー数などのデータにアクセス可能となる。これらのデータベースについては、プログラムとして、
ｈｏｌｅ［？］．ｐａｒ
ｈｏｌｅ［？］．ｌｅｎｇｔｈ
のような変数からアクセスができる。
これまでの説明のようにして、コース選択までの入力操作（図８（ｅ））が完了されると、この場合には、例えば図８（ｆ）のガイド表示に示すようにして、「ラウンド前の準備完了です」のようなテロップを表示させ、ユーザに、ラウンド前の準備としての入力操作が全て完了したことを知らせるようにされる。
【０１１７】
続いて、図９及び図１０によりラウンド中のガイド表示と、これに従ったユーザの手順について説明する。
例えば、上記図８に示した入力操作終了後においては、図９（ａ）に示すようなガイド表示が行われ、第１ホールのティーショットを撮影するように指示が行われる。そして、続いて表示される図９（ｂ）のガイド表示において、被写体となるメンバーを選択するための操作が促される。また、この図９（ｂ）のガイド表示でも、先に抱負を語った場面を録画したファイルの画像データから生成したサムネイル画像を利用して、各メンバーの顔写真を表示している。そして、この各メンバーの顔写真に対してカーソルを移動させて、選択決定操作を行うようにするものである。
【０１１８】
図９（ｂ）に示すガイド表示に対して選択決定操作が行われると、表示部６Ａは図９（ｃ）に示すガイド表示となり、例えば、現在の撮像画像に対して「５秒くらいで撮ってください」というスーパインポーズによる撮像時間の指示と、構図を指定する撮影指示枠が表示される。そして、この状態でユーザはプレーヤがティーショットを行っているところを撮影する（録画操作を行う）ようにされる。また、この場合にも録画操作が終了されると、図９（ｄ）に示すようにして「見直し」「取り直す」「ＯＫ」ボタンが提示されるガイド表示が表示されるのは、先に説明した図８（ｂ）→（ｃ）の手順による撮影時の場合と同様である。
【０１１９】
そして、この場合には図９（ｄ）に示すガイド表示において「ＯＫ」ボタンが操作されると、図９（ｅ）のガイド表示に移行し、今撮影したティーショットの腕前がどの程度であったのかを入力することができるようにされる。ここでは、「素晴らしい」「まあまあ」「チョロ」「てんぷら」の４つのボタンが候補として提示されており、ユーザはこれらのボタンから所望のボタンを選択してクリック操作（決定操作）を行うようにされる。
この図９（ｂ）→図９（ｃ）→図９（ｄ）→図９（ｅ）に示すガイド表示表示は、メンバーの人数分（この場合には３回）繰り返されて、各メンバーのティーショットが撮影できるようにされている。
そして、図９（ｂ）→図９（ｃ）→図９（ｄ）→図９（ｅ）のガイド表示に従った手順により、メンバー全員（３人）のティーショットについての撮影とショット評価の入力が完了したとする。
この段階では、３人のメンバーのティーショットを撮影した録画ファイルは、ｖｉｄｅｏ４，ｖｉｄｅｏ５，ｖｉｄｅｏ６と名前が付けられてディスクへの記録が行われている。そして、プログラム上では、
ｐａｒｔｙ［０］．ｔｅｅｓｈｏｔ＝ｖｉｄｅｏ４；
ｐａｒｔｙ［１］．ｔｅｅｓｈｏｔ＝ｖｉｄｅｏ５；
ｐａｒｔｙ［２］．ｔｅｅｓｈｏｔ＝ｖｉｄｅｏ６；
という形式で、各録画ファイルと共に、誰のショットであるかとの関連付けを行うようにされる。
また、図９（ｅ）のガイド表示に対する入力操作に基づき、例えば
ｐａｒｔｙ［０］．ｔｅｅｓｈｏｔ＿ｑｕａｌｉｔｙ＝ＯＫ；
ｐａｒｔｙ［１］．ｔｅｅｓｈｏｔ＿ｑｕａｌｉｔｙ＝ＧＲＥＡＴ；
ｐａｒｔｙ［２］．ｔｅｅｓｈｏｔ＿ｑｕａｌｉｔｙ＝ＣＨＯＲＯ；
といった形式でショット評価が登録される。この場合には、Ａさんのショットについては「まあまあ（ＯＫ）」ボタンに対するクリック操作が行われ、Ｂさんのショットは「素晴らしい（ＧＲＥＡＴ）」ボタン、Ｃさんのショットについては「チョロ（ＣＨＯＲＯ）」ボタンに対するクリック操作が行われた結果が反映されている。
【０１２０】
上記のようにしてティーショットに関する手順が完了すると、例えば以降は、図９（ｆ）に示すガイド表示が行われる。このガイド表示では、以降はユーザが任意に好みの場面を撮影（ここでは撮像画像の録画行うことと同義である）することを促している。そしてこの場合には、その撮影内容の候補として、風景の撮影に対応する「風景」ボタンと、プレーヤのコメントしている場面の撮影に対応する「コメント」ボタンと、ティーショットよりも以降の任意のショットの撮影に対応する「ショット」ボタンとが用意されている。
ユーザはこれより撮影したいと思う内容に応じて、このボタンのうちの何れかを選択してクリック操作を行うようにされる。
【０１２１】
上記図９（ｆ）に示すガイド表示のもとで、「風景」ボタンに対するクリック操作を行ったとすれば、例えばガイド表示は図１０（ａ）に示すような、風景の撮影を促す内容のものとなる。ここでは、現在の撮像画像に対して「風景を撮ってください」」というテロップが表示されている。ユーザは、このガイド表示が表示されている表示部６Ａを見て撮像画像のモニタをしながら、目的とする風景の撮影を行えばよい。
【０１２２】
また、図９（ｆ）に示すガイド表示上で「コメント」ボタンに対するクリック操作を行ったとすれば、図１０（ｂ）に示すような、プレーヤがコメントしている場面を撮影するためのガイド表示表示が行われる。このガイド表示も、例えば現在の撮像画像に対して「コメントを撮ってください」というテロップと、構図を決めるための撮影指定枠とがインポーズ表示されている。ユーザは、このガイド表示上でモニタしながら、コメントしているユーザを撮影する。
なお、ここでは図示しないが、「コメント」の撮影に際しては、例えば図９（ｂ）に準るようなガイド表示を表示させるなどして、どのプレーヤのコメントの撮影であるのかを指定するための入力操作も行われるものとする。
【０１２３】
或いは、図９（ｆ）に示すガイド表示上で「ショット」ボタンに対するクリック操作を行ったとすれば、図１０（ｃ）に示すガイド表示に移行する。このガイド表示では、これより撮影するショットが行われるホール番号と、そのホールでの打数の入力を促すための表示と、ショットの種類を入力するためのボタン表示（ここでは、「ティー」「アイアン」「トラブル」「パット」ボタンが用意される。また、ここでも図示は省略するが、例えば図９（ｂ）に準ずるガイド表示を出すなどして、どのプレーヤのショットであるのかを指定するための入力操作が促されるものである。
そして、図１０（ｃ）のガイド表示に対する入力操作が完了すると、図１０（ｃ）に示すようにして、プレーヤのショットを５秒くらいで撮影することを促すテロップと撮影指定枠とが撮像画像にインポーズされたガイド表示が表示され、ユーザはショットの撮影を行うようにされる。
なお、説明の重複を避けるためにここでは省略しているが、この場合にも、プレーヤのショットの撮影が終了したら、例えば図９（ｄ）（ｅ）に示したような見直し、撮り直しのためのガイド表示や、ショットの評価を入力するガイド表示が表示されるようにしてよいものである。
そしてユーザは、プレー中において、必要に応じて上記図９（ｆ）〜図１０（ｄ）により説明した手順を繰り返すようにされる。
【０１２４】
ここで、上記図９（ｆ）〜図１０（ｄ）の手順により得られるプログラム内容の例を挙げておく。、
先ず、ショットの撮影を行った場合に対応するものとして、例えば第４ホールの２打目でのＡさんのトラブルショットがｖｉｄｅｏ７として記録されたとすると、例えば、
ｔｒａｃｋ［０］．ｔｒａｃｋ＝ｖｉｄｅｏ７；
ｔｒａｃｋ［０］．ｔｙｐｅ＝ＳＨＯＴ；
ｔｒａｃｋ［０］．ｈｏｌｅ＝４；
ｔｒａｃｋ［０］．Ｓｈｏｔｎｕｍｂｅｒ＝２；
ｔｒａｃｋ［０］．Ｓｈｏｔｔｙｐｅ＝ＴＲＯＵＢＬＥ；／／ＴＲＯＵＢＬＥはトラブルショットを意味する。
ｔｒａｃｋ［０］．ｐｅｒｓｏｎｎｕｍｂｅｒ＝０；／／ｐａｒｔｙ［０］がＡさんである。
のような付加情報が登録されることになる。
【０１２５】
そして、このショットに対するＢさんのコメントをｖｉｄｅｏ８として記録していたとすると、例えば、
ｔｒａｃｋ［１］．ｔｒａｃｋ＝ｖｉｄｅｏ８；
ｔｒａｃｋ［１］．ｔｙｐｅ＝ＣＯＭＭＥＮＴ；
ｔｒａｃｋ［１］．ｐｅｒｓｏｎｎｕｍｂｅｒ＝０；
のようして付加情報が登録されることになる。
【０１２６】
また、上記Ｂさんのコメントを撮影した次に、風景をｖｉｄｅｏ９として撮影していたとすると、
ｔｒａｃｋ［２］．ｔｒａｃｋ＝ｖｉｄｅｏ９；
ｔｒａｃｋ［２］．ｔｙｐｅ＝ＳＣＥＮＥ；
ｔｒａｃｋ［２］．ｈｏｌｅ＝４；／／何ホール目のときに撮影されたものであるのかが示される
のようして付加情報が登録されることになる。なお、この付加情報には、この風景が何ホール目で撮影されているのかを示す内容が含まれているが、この何ホール目であるのかの情報は、これより以前の撮影状況（例えばこれより以前に撮影されたショットに対応して入力されたホール番号等の情報）から類推して記録することができる。
【０１２７】
そして、例えば、プレー終了に対応する所定の入力操作（ここでは図示せず）が行われたり、これまでの撮影状況からプレーが終了したことが推測されたような場合には、先ず図１０（ｅ）に示すスコア入力のためのガイド表示が行われる。ユーザは、このガイド表示に対して、例えばジョグダイヤル３１１を操作することで、各メンバーごとスコア数値を入力するようにされる。なお、このようなスコア入力画面は、プレー中においても必要に応じて呼び出せるようにして、適宜スコア入力が可能なように構成してもよいものである。
スコア入力に対応したプログラムとしては、
ｐａｒｔｙ［０］．ｓｃｏｒｅ＿ｈｏｌｅ［１］＝３；
ｐａｒｔｙ［０］．ｓｃｏｒｅ＿ｈｏｌｅ［２］＝５；
のようにして記録が行われることになる。
【０１２８】
そして、メンバー全員のスコア入力が終了したとされると、例えば図１０（ｆ）に示すガイド表示が表示される。このガイド表示表示は、プレー後において各メンバーがコメントを行っている場面の撮影を促すためのもので、この場合には、図のようにこれより撮影すべきメンバー（図９（ｂ）のようにメンバーの顔がサムネイル画像として表示されている）を選択するための画面が先ず表示される。
この画面上で、ユーザが被写体となるメンバーを選択するための操作を行うと、例えばガイド表示としては、先に図９（ｃ）に示したような数秒間の撮影を促すガイド表示と、図９（ｄ）に示すような撮影後における確認を促すガイド表示が行われるようにされ、ユーザはこの表示に従って撮影や録画状態の確認、撮り直し等を行うようにされる。そして、同様の手順を踏んで、メンバー全員がコメントを行っている場面を撮影するようにされる。
例えば３人のメンバーのコメントをＡさん、Ｂさん、Ｃさんの順で撮影し、これらがそれぞれファイル名ｖｉｄｅｏ１０、ｖｉｄｅｏ１１、ｖｉｄｅｏ１２の録画ファイルとして記録されたとすると、プログラムとしては、
ｐａｒｔｙ［０］．ｅｎｄｃｏｍｍｅｎｔ＝ｖｉｄｅｏ１０；
ｐａｒｔｙ［１］．ｅｎｄｃｏｍｍｅｎｔ＝ｖｉｄｅｏ１１；
ｐａｒｔｙ［２］．ｅｎｄｃｏｍｍｅｎｔ＝ｖｉｄｅｏ１２；
のようにして各録画ファイルに対する関連付けが行われるようにされる。
【０１２９】
これまでの全ての手順の完了を以て、編集素材情報として、映像作品作成のための所要の情報の入力操作に基づくプログラム情報と、及び編集の素材となる録画ファイル（画像／音声情報）が得られることになる。
【０１３０】
なお、上記図８〜図１０に示すガイド表示が行われているときには、実際には、編集用アプリケーションプログラムに格納されている露出制御値に基づいて、当該ビデオカメラ装置のレンズブロックにおけるプログラムＡＥ(Automatic Exposure)機能に対する補正が行われている状態にあるものとされる。
つまり、編集用アプリケーションプログラムとして設定されている脚本に従えば、ガイド表示の下で編集素材を集めるための撮影はどのような状況で行われるのかは容易に想定し得るものである。例えばゴルフコンペであれば、状況としては屋外にて撮影されることになる。
そこで、予測される撮影状況に適したＡＥに対する補正値を予め編集用アプリケーションプログラムに用意し、実際のガイド表示に従った撮影時にはこの補正値により自動的にＡＥ補正を行うようにされる。例えばゴルフコンペに対応する場合には、屋外での撮影に最適とされるＡＥの補正値を編集用アプリケーションプログラムに用意し、この補正によってプログラムＡＥを制御することになる。これにより、例えば、ユーザが特にＡＥのプログラム変更等の操作を行わなくとも、ＡＥプログラムがほぼ最適な状態を維持するように制御され、結果的には良好な画質の編集素材としての録画ファイルを得ることが可能になるものである。
【０１３１】
８−３．編集再生（映像作品としての再生）
そして、本実施の形態のビデオカメラ装置においては、編集用のアプリケーションプログラムの下で設定されている脚本に従って、上記のようにして得られた入力情報を利用して、録画ファイルを素材とする映像作品を作成するための編集処理を行う。この編集処理は、各録画ファイルの再生順を含む再生タイミングや、再生された録画ファイルに対するスーパインポーズなどを指定するスクリプトを構成するという処理により実現される。そして、このようにして得られたスクリプトを解釈して録画ファイルの再生及び、特殊効果の付与等のための画像処理を実行することで、映像作品としての再生が行われる。なお、作成されたスクリプトは、これに対応する編集用アプリケーションプログラムが格納されているディスクの補助データトラック(Auxiliary Data Track)に記録されることで保存が行われるようにされる。
【０１３２】
そこで、先ず、図８〜図１０により説明した手順応じて記述されたスクリプトにより作成される映像作品の再生態様例について、図１１〜図１３を参照して説明する。なお、以降述べる映像作品の再生態様例に対応する記述内容、及びスクリプトの生成方法については後述する。
【０１３３】
例えば、ユーザは、ゴルフ場で撮影に使用していたゴルフ編集用ディスク（この段階では、編集素材となる録画ファイルや映像作品の編集のためのスクリプトは既に記録されている状態にある）をビデオカメラに装填して、再生のための操作を行うようにされる。
この操作に応答して、ビデオカメラではディスクからスクリプトの読み出しを行い、このスクリプトの解釈を行いながら録画ファイルの再生及び画像／音声信号処理を行うことで、次に示すような映像作品の再生を実現する。
【０１３４】
この場合、先ず最初には、図１１（ａ）に示すようなオープニングタイトルが効果音の出力と共に表示される。
そして、続いては、図１１（ｂ）に示すようにしてメンバー紹介の画像が表示される。ここでは、メンバーの顔写真がその名前と共に表示されている。このメンバーの顔写真は、図９（ｂ）のガイド表示で利用されたものを利用するようにすればよい。つまり、図９（ｂ）のガイド表示に利用されたサムネイル画像は、現場での入力操作及び撮影時においてディスクのサムネイルトラックに対して記録が行われていたものである。
【０１３５】
続いては、例えば図１１（ｃ）に示すようにして、Ａさんが抱負を語る場面が動画（ｖｉｄｅｏ１として記録された録画ファイル）により表示される。この際には、ｖｉｄｅｏ１の録画ファイルを再生しているのであるから、音声によりＡさんが抱負を語る音声が同期して出力される。また、ここでは「今日の意気込みを語るＡさん」のようにして文字表示（スーパインポーズ表示Ｓｉｍｐ）が行われる。このメンバーが抱負を語る場面の表示は、Ａさんに続いて、同様にしてＢさん、Ｃさんについても行われる（ｖｉｄｅｏ２，ｖｉｄｅｏ３の再生）。
【０１３６】
この後は、各メンバーのティーショットの場面が表示される。例えばここでは、上記図１１（ｃ）に示した各メンバーの抱負のコメント場面の表示の後において、図１１（ｄ）に示すようにして、Ａさんがティーショットをしている場面が表示された状態が示されている（ｖｉｄｅｏ４）。ここでは、「１Ｈ ３００ｙｄ ｐａｒ５」のようにしてそのホールの情報を示すスーパインポーズ表示Ｓｉｍｐと、「Ａさんティーショット！」いうその場面を説明するスーパインポーズ表示Ｓｉｍｐが行われている。更には、素晴らしいショットであることを効果的に説明する「ＧＲＥＡＴ」の文字によるスーパインポーズ表示Ｓｉｍｐが行われている。例えばこの「ＧＲＥＡＴ」のスーパインポーズ表示Ｓｉｍｐは、図９（ｅ）に示したガイド表示従った入力操作に応じて表示されるものであるが、このように、本実施の形態では、例えば編集効果として、このようなデザインのスーパインポーズ表示Ｓｉｍｐが自動的に表示されるように構成されるものである。このようなティーショットの場面の表示も、メンバー全員分について順に行われるものである（ｖｉｄｅｏ５，６）。なお、この際も録画ファイルを再生していることで基本的な表示が得られている以上、このとき同時に記録された音声を再生出力しても構わないものであり、これは容易に実現可能である。
【０１３７】
この後は、例えばティーショット後において現場で任意に撮影された録画ファイルの画像音声が、何らかの所要の編集効果が与えられて出力される。
この場合には、図１１（ｄ）に示した各メンバーのティーショット場面の表示後において、図１２（ａ）に示すようにして、Ａさんのトラブルショットの場面（ｖｉｄｅｏ７として記録されたもの）が表示される。
ここでは、スーパインポーズ表示Ｓｉｍｐとしてホールの情報を示す内容と、Ａさんがトラブルショット中にあることを現在のスコアと共に示す内容とが挿入されている。
【０１３８】
続いては、例えば図１２（ｂ）に示すように、ｖｉｄｅｏ８を再生することで、トラブルショット後のコメントをしているＡさんの動画が表示され、このときのコメントの音声も出力される。また、ここではスーパインポーズ表示Ｓｉｍｐとして、例えば「コメントするＡさん」のように現在の状況を説明するものと、「４Ｈ終了現在のスコア＋８」などのようにプレーの進行過程及びスコアを示すものとが表示されている。
【０１３９】
また、この場合には、上記図１２（ｂ）に続いて、ユーザがｖｉｄｅｏ９として撮影した風景として、或るホールのグリーンを撮影した動画像（又は静止画像）が図１２（ｃ）に示すようにして表示される。この場合には、編集用アプリケーションプログラムで用意したＢＧＭが適当に選択されて音声として出力されている。このときには、音声出力としてはＢＧＭだけでもよいし、このｖｉｄｅｏ９の録画ファイルから再生して得られた音声に対して、ＢＧＭを合成して出力するようにしても構わない。
【０１４０】
そして、このような表示が行われ、ゲーム終了までの映像出力が行われたとすると、表示画面としては例えば図１３（ａ）に示すように。これまでの各メンバーの成績を示すスコアが表示される。このスコア表示は、図１０（ｅ）に示したスコア入力操作により得られた情報に基づいて得られるものである。
【０１４１】
そして、スコア表示が終了すると、エンディングタイトルとして、例えば図１３（ｂ）に示すような形態による表示が行われる。ここでは、例えば編集用アプリケーションプログラムで用意した、にっこりと笑っているキャラクタの画像が表示されていると共に、「というわけで、今回は、」「Ｂさん優勝！」という、優勝者を効果的に示すスーパインポーズ表示Ｓｉｍｐが表示されている。この優勝者の特定は、スクリプトの作成方法でも後述するが、図１０（ｅ）に示したスコア入力操作により得られた各メンバーのスコアを参照することで行われるものである。
このエンディングタイトルの表示の終了を以て、映像作品としての再生が終了する。
【０１４２】
８−４．スクリプトの内容
続いて、上記図１１〜図１３に示す映像作品としての表示を実現するためのスクリプトの内容を示す。
前述したように、本実施の形態のビデオカメラでは、図８〜図１０に示したようなガイド表示に従って得られた入力情報と、録画ファイルとして記録された編集素材としてのファイルを組み合わせて使用することで、スクリプトファイルと呼ばれるメタ情報を構成する。このスクリプトファイルの構築は、ガイド表示に従った情報入力及び撮影が終了した後の所要の機会（実際には直後であることが好ましい）において、編集用アプリケーションプログラムが実行されている下で、例えばビデオコントローラ３８が、内部に搭載されているＸＭＬのサブセットを利用して実行するものとされる。
ここでは、ＳＭＩＬ文法に基づき、スーパインポーズにＪＡＶＡ Ａ４３１ｐｐｌｅｔを用いた例を示す。

【０１４３】
なお、上記スクリプトにおけるｓｕｐｅｒｉｍｐｏｓｅアプレットにより指定されたテキストをスーパインポーズさせるための画像処理としては、例えば次のようにして実行すればよい。
【０１４４】
１つには、ビデオコントローラ３８及びデータ処理／システムコントロール回路３１により実現されるキャラクタジェネレータ及びオンスクリーンディスプレイの機能を利用するものである。つまり、ビデオコントローラ３８では、解釈を行ったスクリプトが、ｓｕｐｅｒｉｍｐｏｓｅアプレットにより指定されたテキストを表示すべきものであった場合には、この指定されたテキストの文字／シンボル情報を発生させる。そして、この発生された文字／シンボル等が再生されている録画ファイルの画像上にて所定の位置に表示されるように、データ処理／システムコントロール回路３１に対する制御を実行するものである。
【０１４５】
また、図１１（ａ）の「柏ＣＣゴルフコンペ」や図１１（ｄ）の「ＧＲＥＡＴ」などのようにデザイン化が施されたスーパインポーズ表示Ｓｉｍｐの文字については、上記画像処理に従ってその画像データを生成することも可能であるが、例えば、上記のような特殊なデザインのものについては、予め編集用アプリケーションプログラムのデータとして、所要のディレクトリにファイルとして記録しておくようにして、この画像データを必要に応じて読み出して、録画ファイル（ｖｉｄｅｏ）の再生画像に重畳するように処理を行えば（このような画像処理はデータ処理／システムコントロール回路３１にて行われれる）、ビデオコントローラ３８及びデータ処理／システムコントロール回路３１の処理負担が軽くなる。
【０１４６】
なお、例えば上記スーパインポーズ処理は、先に図８〜図１０に示した、撮像画像を背景としているガイド表示におけるテロップの表示や、撮影指定枠の表示を実現する場合にも準用される。
つまり、ビデオコントローラ３８は、編集用アプリケーションプログラムが用意したテロップや撮影指定枠の画像データファイルをディスクから読み出して、ビデオ信号処理部３に供給するためのを制御処理を実行する。ビデオ信号処理部３では、例えばこの供給された画像データファイルについてデコード処理を施す。
そして、データ処理／システムコントロール回路３１においては、ビデオコントローラ３８の制御に従って、デコードされたテロップや撮影指定枠の画像データが、カメラブロックから供給される撮像画像上の所要の位置に表示されるように画像合成処理を行う。そして、この画像データを表示部６Ａに表示出力するようにされる。
【０１４７】
８−５．スクリプトの生成方法
続いて、本実施の形態の編集用アプリケーションプログラムが起動されている環境のもとで得られるスクリプトの生成方法について説明する。
ここでは、具体例として上記した、図１１〜図１３に示す映像作品としての表示を実現するためのスクリプト内容を生成する場合を例に挙げ、各スクリプトのセクションについて、入力した変数やその他のセットの情報からどのようにウイザードが生成されていくかを見ていくことにする。また、ここではパラメーターの算出方法をＣ＋＋言語で示すこととする。
セクション１（図１１（ａ））
ｃｏｕｒｓｅ＝ｃｏｕｒｓｅｎａｍｅ；／／ユーザーの選択したコースに従う
ｄａｔｅ＝ｇｅｔｄａｔｅ（）；／／セット（例えばビデオコントローラ３８）が備えるカレンダー機能からｄａｔｅを受け取る。

セクション８（図１３（ａ））
予め入力されたスコアをｓｃｏｒｅ．ｔｘｔというファイルに変換してディスクに記録する。
セクション９（図１３（ｂ））
先ず合計スコアが最小のメンバーを探索する。それがｉ番目の人の場合
ｖｉｄｅｏ＝ｐａｒｔｙ［ｉ］．ｅｎｄｃｏｍｍｅｎｔ；
ｔｏｐｃａｐｔｉｏｎ＝″というわけで、今回は″；
ｂｏｔｔｏｍｃａｐｔｉｏｎ″ｖａｌｕｅ＝ｐａｒｔｙ［ｉ］．ｎａｍｅ＋″さん優勝″；
スクリプトはこのような演算を実行することで、図８〜図１０により説明した入力操作により得られる入力情報、及び撮像画像の録画ファイルから導き出すことができるものである。
【０１４８】
８−６．処理動作
続いて、これまで説明した編集動作を実現するための処理動作例について、図１３及び図１４のフローチャートを参照して説明する。なお、図１３及び図１４に示す処理動作は、例えばビデオコントローラ３８がマスターコントローラとして機能したうえで、必要に応じて、データ処理／システムコントロール回路３１、ドライバコントローラ４６及びカメラコントローラ２５が制御処理（或いは信号処理）を実行することにより実現される。また、この処理は、編集用アプリケーションプログラムが起動されている環境のもとで実行される処理動作となる。
【０１４９】
図１４に示す処理動作は、例えば図８〜図１０に示したガイド表示と、このガイド表示に従って行われた情報入力（撮像画像の録画を含む）に基づいてスクリプトを生成するまでの処理が示されている。
先ず、ユーザの操作部７に対する所定操作によって、編集用アプリケーションプログラムのガイド機能表示を動作させるための指示が行われたとすると、ビデオコントローラ３８は、ステップＳ１０１に進んで、装填されているディスクから編集用アプリケーションプログラムを読み出すための制御処理を実行する。
そして、続くステップＳ１０２において、例えばビデオコントローラ３８内部のＲＡＭを利用して、編集用アプリケーションプログラムを起動させるための処理を実行する。
【０１５０】
次のステップＳ１０３においては、編集用アプリケーションプログラムに含まれている、当該ビデオカメラ装置の撮像光学系に対する露出制御値を参照し、この露出制御値に基づいて、レンズブロック１におけるＡＥ(Automatic Exposure)機能に対する露光補正を行うための制御を実行する。この処理は、例えばビデオコントローラ３８がカメラコントローラ２５に対してＡＥ補正のための制御を実行するように指示する。カメラコントローラ２５では上記露出制御値に基づいてＡＥの補正が適切に行われるようにレンズブロック１に対する制御を実行することになる。
【０１５１】
そして、次のステップＳ１０４において、起動された編集用アプリケーションプログラムに従い、ガイド表示を行うための制御処理を開始する。これにより、以降は例えば表示部６Ａに対してガイド表示が行われることになる。
【０１５２】
ステップＳ１０５は、ガイド表示により促される指示に従って逐次行われた入力操作、及び撮影（録画）により得られるコンテンツ（入力情報のことであり、ここでは操作入力情報、及び録画ファイルとされる）を保存するための処理が実行される。
つまり、例えば図８〜図１０にて説明したように、ユーザはガイド表示ごとに促される情報の入力に従って、所要の入力操作又は録画を行うようにされるが、これらの入力操作により得られた情報及び、録画により得られた録画ファイルを編集素材として保持する処理を実行するものである。ここでは、操作入力により得られた入力情報（操作入力情報）は、例えばビデオコントローラ３８内部のＲＡＭに保持するようにされているものとする。また、撮影により得られた録画ファイルについては、ディスクのフォルダ内のディレクトリに対してファイル（トラック）として記録を行うことになる。
そして、例えば、ガイド表示に従った情報入力が全て行われたとされる（つまりガイド表示の終了に至る）と、ステップＳ１０６に進むようにされる。
【０１５３】
ステップＳ１０６においては、保持されたコンテンツを編集用アプリケーションプログラムとして予め設定されている脚本に従って再構成するための処理が実行される。つまりは、図８〜図１０による説明に並行して記述したプログラム内容を設定するものである。ここでは、このステップＳ１０５の処理が、ガイド表示の終了後に実行されるものとしているが、例えば実際には、ステップＳ１０５の処理として、コンテンツの獲得（操作入力情報の保持、及び録画ファイルの記録）が行われるごとに、ステップＳ１０６の処理が実行されるようにしてもよいものである。
【０１５４】
上記ステップＳ１０６の処理が終了されると、ビデオコントローラ３８はステップＳ１０７に進み、上記のようにして再構成されたコンテンツの内容を利用し、編集用アプリケーションプログラムにより予め設定されている脚本に従ってスクリプトを生成するための処理を実行する。これにより、例えば先に示したような記述内容によるスクリプトが得られる。
【０１５５】
そして、次のステップＳ１０８では、上記のようにして生成されたスクリプトを、スクリプトファイルとしてディスクの補助データトラックに記録するための制御処理を実行して、これまでの処理を終了するようにされる。
これまでの処理により、ディスクには予め記録されていた編集用アプリケーションプログラムに加え、編集素材となる録画ファイル、及び編集内容を指定するための記述がされたスクリプトファイルが記録されることになる。
【０１５６】
続いて、上記のようにして得られたディスクを利用した編集再生、つまり編集素材となる録画ファイルを基として映像作品を再生するための処理動作について図１５のフローチャートを参照して説明する。
【０１５７】
例えば映像作品の再生を開始させるための所要の操作が操作部に対して行われたとすると、ビデオコントローラ３８は、この図１５に示す処理に移行する。
この図に示す処理においては、先ずステップＳ２０１においてディスクに記録されているスクリプトを読み出すことが行われる。ここで読み出されるべきスクリプトとは、事前の編集用アプリケーションプログラムの実行に従って作成された、映像作品再生ための内容が記述されたスクリプトである。
ディスクから読み出されたスクリプトは、例えばバッファメモリ３２の所定領域に対して格納される。また、ビデオコントローラ３８内部のＲＡＭの記憶容量に余裕あれば、この内部ＲＡＭに対して格納するように構成することも考えられる。
【０１５８】
そしてステップＳ２０２では、上記のようにしてディスクから読み出されたスクリプトファイルについての解釈を開始し、続くステップＳ２０３の処理として、解釈されたスクリプトの記述内容に従った再生処理を実行する。つまり、スクリプトの記述に従って必要とされる所要の録画ファイル（及びＢＧＭ用の音声トラックなどのファイル）をディスクから読み出して、これを画像／音声として出力するための再生処理が実行されるように、所要の機能回路部に対する制御を実行する。また、これと共に、例えば＜ａｐｐｌｅｔ＞タグ等に対応した、所要の文字やシンボルのスーパインポーズ表示が行われるようにするための画像信号処理や、ＢＧＭの出力などのための音声信号処理等を実行する。
このステップＳ２０３の処理によって、例えば図１１〜図１３に示した映像作品としての画像／音声の再生出力態様が得られることになるものである。
【０１５９】
そして、ステップＳ２０４の処理として、スクリプトの解釈の終了が行われたとされると、これまでの処理を終了することになる。つまり、映像作品の再生が最後まで行われた状態で、これまでの再生動作が終了されることになる。なお、この図には示していないが、例えば停止操作が行われれば、映像作品の再生はその時点で終了され、また、一時停止操作が行われれば、一時停止操作が行われていた時点で表示されていた画像が表示された状態を維持し、スクリプト解釈の進行も一時停止されるように制御処理が実行されるものである。
【０１６０】
なお、上記実施の形態は、ゴルフコンペに対応する映像作品を作成するための編集処理を実現するための構成について説明したが、これはあくまでも一例であり、他の目的に従った映像作品を作成する場合も、これまで説明した構成に従って実現することが可能である。
【０１６１】
また、上記実施の形態として示したガイド表示や、映像作品として仕上がった状態での各種編集効果の与え方などは、実際に応じて適宜変更可能である。
また、本実施の形態において採用されるスクリプトの言語としては、ＳＭＩＬに限定されるものではなく、他の言語が採用する構成を採っても構わないものである。
【０１６２】
また、例えば、上記実施の形態として図８〜図１０に示した編集操作例は、あくまでも一例であって、一般のユーザによっても簡易とされるような操作形態であれば、他の操作形態や他の表示形態が採られても構わない。一例として、表示部６Ａがタッチパネルとしての機能を有するように構成して、図８〜図１０による説明に準ずるような操作を、表示部６Ａに対して指や何らかのポインティングデバイスを用いてポインティングするようにして行うようにすることも考えられる。
【０１６３】
更に、本実施の形態のビデオカメラとしては、ビデオ記録再生部位として、ＭＤ−ＤＡＴＡ２に基づくディスク記録再生装置としたが、ビデオ記録再生部位としては、本実施の形態としての構成の他、他の種類のディスク状記録媒体に対応する記録再生装置とされても構わない。
更に、動画像データを圧縮するために本実施の形態では、ＭＰＥＧ２方式を採用するものとして説明したが、例えば他の動画像データの圧縮符号化が可能な方式が採用されて構わない。また、静止画データ及び音声データについての圧縮方式も、本実施の形態として例示したもの（ＪＰＥＧ，ＡＴＲＡＣ２等）に限定される必要は特にない。
【０１６４】
【発明の効果】
以上説明したように本発明は、編集処理のためのプログラム（編集用アプリケーションプログラム）として、編集のために必要となる情報の入力を促すためのガイド機能としてのＧＵＩを実現するもの（入力指示プログラム）を用意し、このガイド表示に従って、入力操作による所要の入力情報の入力、及び撮像画像（音声も含む）のファイルの記録媒体への記録を行うと、上記プログラム（編集プログラム）に従った編集処理として、上記入力操作により得られた入力情報に基づいて、撮像画像のファイルについて所要の再生出力態様を与えるためのスクリプトを生成して記録媒体に記録するようにされる。そして、再生時においては、このスクリプトの記述内容に従った編集効果を与えながら上記撮像画像のファイルの再生を行うようにされる。
つまり、ユーザは、自分がビデオカメラなどにより撮影して得た画像、音声などのソースに対して特に複雑な編集処理を施すことなく、撮影時において、ガイド表示に従った入力操作や撮影を行うだけで、結果的に相応に高度な品質の編集が与えられた映像作品等を作成することができるという効果を有している。
【０１６５】
そして、上記発明に対応する記録媒体として、画像情報及び音声情報、上記ガイド機能を有する編集プログラム、及びスクリプトファイルが記録される各記録領域を設定したものを提供することで、ユーザが目的とする編集作業と編集再生は、本発明による１つの記録媒体で賄うことができる。つまり、或る目的に従った編集プログラムが記録されている１つの記録媒体をこれに対応する記録再生装置により記録再生することで、編集のための入力操作や撮影などの作業と、作成されたスクリプトに基づく編集再生とを行うことができる。これにより、編集に際してのユーザの作業の手間が省かれる他、編集された映像ソースのライブラリ管理も容易なものとすることができる。

Hereinafter, an image processing apparatus according to an embodiment of the present invention will be described. The image processing apparatus according to this embodiment is mounted on a portable video camera in which a camera apparatus unit and a recording / reproducing apparatus unit capable of recording and reproducing images (still images or moving images) and audio are integrated. Take the case as an example.

[0012]
1. Disc format
The recording / reproducing apparatus unit mounted on the video camera of this example corresponds to a format called MD data which records / reproduces data corresponding to a mini-disc (magneto-optical disc). As this MD data format, two types of formats called MD-DATA1 and MD-DATA2 have been developed. The video camera of this example is capable of recording at a higher density than MD-DATA1. It is assumed that recording and reproduction are performed in accordance with the format. First, the disk format of MD-DATA2 will be described.
[0013]
1 and 2 conceptually show an example of a track structure of a disk as MD-DATA2. FIGS. 2A and 2B are a cross-sectional view and a plan view, respectively, showing an enlarged portion surrounded by a broken line A in FIG.
As shown in these figures, there are two types of grooves (grooves), a wobbled groove WG provided with wobble (meandering) and a non-wobbled groove NWG provided with no wobble in advance on the disk surface. It is formed. The wobbled groove WG and the non-wobbled groove NWG exist in a double spiral shape on the disk so as to form a land Ld therebetween.
[0014]
In the MD-DATA2 format, the land Ld is used as a track. Since the wobbled groove WG and the non-wobbled groove NWG are formed as described above, the track Tr.A, Tr. The two tracks B are independently formed in a double spiral (double spiral) shape.
The track Tr · A is a track in which the wobbled groove WG is positioned on the outer peripheral side of the disk and the non-wobbled groove NWG is positioned on the inner peripheral side of the disk.
On the other hand, the track Tr · B is a track in which the wobbled groove WG is located on the inner circumference side of the disk and the non-wobbled groove NWG is located on the outer circumference side of the disk.
That is, it can be considered that the wobble is formed only on one side on the outer peripheral side of the disk with respect to the track Tr · A, and the wobble is formed only on one side on the inner peripheral side of the disk with respect to the track Tr · B. .
In this case, the track pitch is the distance between the centers of the adjacent tracks Tr · A and Tr · B, and the track pitch is 0.95 μm as shown in FIG.
[0015]
Here, the wobble formed in the groove as the wobbled groove WG is formed based on a signal in which a physical address on the disk is encoded by FM modulation + biphase modulation. Therefore, it is possible to extract the physical address on the disc by demodulating the reproduction information obtained from the wobbling given to the wobbled groove WG at the time of recording and reproduction.
Further, the address information as the wobbled groove WG is valid for the tracks Tr · A and Tr · B in common. In other words, the track Tr · A located on the inner periphery across the wobbled groove WG and the track Tr · B located on the outer periphery share the address information by wobbling given to the wobbled groove WG. .
Such an addressing method is also called an interlace addressing method. By adopting this interlace addressing method, for example, it is possible to reduce the track pitch while suppressing crosstalk between adjacent wobbles. The method of recording addresses by forming wobbles on the groove is also referred to as the ADIP (Address In Pregroove) method.
[0016]
Further, as described above, it is possible to identify which of the tracks Tr · A and Tr · B sharing the same address information is being traced as follows.
For example, when the 3-beam method is applied and the main beam is tracing the track (land Ld), the remaining two side beams trace the grooves located on both sides of the track being traced by the main beam. It is possible to make it.
[0017]
FIG. 2B shows a state where the main beam spot SPm is tracing the track Tr · A as a specific example. In this case, of the two side beam spots SPs1 and SPs2, the inner side side beam spot SPs1 traces the non-wobbled groove NWG, and the outer side side beam spot SPs2 traces the wobbled groove WG. become.
On the other hand, although not shown, if the main beam spot SPm is tracing the track Tr · B, the side beam spot SPs1 traces the wobbled groove WG and the side beam spot SPs2 is non-wobbled groove. NWG will be traced.
As described above, when the main beam spot SPm traces the track Tr · A and the track Tr · B, the groove to be traced by the side beam spots SPs1, SPs2 is necessarily a wobbled groove. The WG and the non-wobbled groove NWG are interchanged.
[0018]
As a detection signal obtained by the photodetector by reflection of the side beam spots SPs1 and SPs2, different waveforms are obtained depending on which one of the wobbled groove WG and the non-wobbled groove NWG is traced. Based on, for example, it is determined which of the current side beam spots SPs1 and SPs2 is tracing the wobbled groove WG (or the non-wobbled groove NWG), so that the main beam is track Tr · A, Tr · Which of B is traced can be identified.
[0019]
FIG. 3 is a diagram showing the main specifications of the MD-DATA2 format having the track structure as described above in comparison with the MD-DATA1 format.
First, the MD-DATA1 format has a track pitch of 1.6 μm and a pit length of 0.59 μm / bit. The laser wavelength λ is 780 nm, and the aperture ratio NA of the optical head is 0.45.
As a recording method, a groove recording method is adopted. That is, the groove is used as a track for recording and reproduction.
As an addressing method, a single spiral groove (track) is formed, and a wobbled groove in which wobbles as address information are formed on both sides of the groove is used.
[0020]
An EFM (8-14 conversion) system is adopted as a recording data modulation system. As an error correction method, ACIRC (Advanced Cross Interleave Reed-Solomon Code) is adopted, and a convolution type is adopted for data interleaving. For this reason, the data redundancy is 46.3%.
[0021]
Further, in the MD-DATA1 format, CLV (Constant Linear Velocity) is adopted as a disk drive system, and the linear velocity of CLV is set to 1.2 m / s.
The standard data rate at the time of recording / playback is 133 kB / s, and the recording capacity is 140 MB.
[0022]
On the other hand, the MD-DATA2 format that can be supported by the video camera of this example is that the track pitch is 0.95 μm and the pit length is 0.39 μm / bit, both of which are shorter than the MD-DATA1 format. I understand. For example, in order to realize the above pit length, the laser spot λ = 650 nm and the aperture ratio NA = 0.52 of the optical head are used to narrow the beam spot diameter at the in-focus position and widen the band as the optical system. .
[0023]
As described with reference to FIGS. 1 and 2, the land recording method is adopted as the recording method, and the interlace addressing method is adopted as the address method. As a recording data modulation method, an RLL (1, 7) method (RLL: Run Length Limited) adapted to high-density recording is adopted, an error correction method is an RS-PC method, and data interleaving is used. Block complete type is adopted. As a result of adopting each of the above methods, the data redundancy can be suppressed to 19.7%.
[0024]
Even in the MD-DATA2 format, CLV is adopted as the disk drive system, but the linear velocity is 2.0 m / s, and the standard data rate at the time of recording and reproduction is 589 kB / s. . As a recording capacity, 650 MB can be obtained, and when compared with the MD-DATA1 format, a recording density of more than four times is realized.
For example, when moving images are recorded in the MD-DATA2 format, when moving image data is compression-encoded by MPEG2, 15 minutes to 17 minutes in time depending on the bit rate of the encoded data. Can be recorded. Further, assuming that only audio signal data is recorded, when audio data is subjected to compression processing by ATRAC (Adaptve Transform Acoustic Coding) 2, recording can be performed for about 10 hours.

The video output terminal T1 is a terminal that outputs a reproduction image signal or the like to an external video device, and the headphone / line terminal T2 is a terminal that outputs a reproduction audio signal to an external audio device or headphones. The I / F terminal T3 is, for example, an input / output terminal of an interface for performing data transmission with an external data device.
[0028]
Furthermore, each part of the main body 200 is provided with various operators (300301 and 304 to 310) for user operations.
The main dial 300 is an operator for setting on / off of the video camera, recording operation, and reproduction operation. As shown in the figure, when the main dial is in the “OFF” position, the power is turned off, and when the main dial is rotated to the “STBY” position, the power is turned on and the recording operation is on standby. Further, by turning to the position “PB”, the power is turned on and the standby state of the reproduction operation is set.

[0033]
3. Internal configuration of the video camera
FIG. 4 is a block diagram showing an example of the internal configuration of the video camera of this example.
In the lens block 1 shown in this figure, for example, an optical system 11 configured with an imaging lens, a diaphragm, and the like is actually provided. The camera lens 201 shown in FIG. 6 is included in the optical system 11. In addition, the lens block 1 includes a motor for causing the optical system 11 to perform an autofocus operation, a zoom motor for moving the zoom lens based on the operation of the zoom key 304, and the like. Supplied as
[0034]
The camera block 2 is provided with a circuit unit for mainly converting image light photographed by the lens block 1 into a digital image signal.
The CCD (Charge Coupled Device) 21 of the camera block 2 is given an optical image of the subject that has passed through the optical system 11. The CCD 21 performs photoelectric conversion on the optical image to generate an imaging signal and supplies it to a sample hold / AGC (Automatic Gain Control) circuit 22. The sample hold / AGC circuit 22 performs gain adjustment on the image pickup signal output from the CCD 21 and performs waveform shaping by performing sample hold processing. The output of the sample hold / AGC circuit 2 is supplied to the video A / D converter 23 to be converted into digital image signal data.
[0035]
Signal processing timing in the CCD 21, sample hold / AGC circuit 22, and video A / D converter 23 is controlled by a timing signal generated by a timing generator 24. In the timing generator 24, a clock used for signal processing in a data processing / system control circuit 31 (in the video signal processing circuit 3) described later is input, and a required timing signal is generated based on this clock. Is done. Thereby, the signal processing timing in the camera block 2 is synchronized with the processing timing in the video signal processing unit 3.
The camera controller 25 performs necessary control so that each functional circuit unit provided in the camera block 2 operates properly, and performs autofocus, automatic exposure adjustment, aperture adjustment, zoom, and the like on the lens block 1. It is supposed to perform control for
For example, in the case of autofocus control, the camera controller 25 controls the rotation angle of the focus motor based on focus control information obtained according to a predetermined autofocus control method. As a result, the imaging lens is driven so as to be in a just-focus state.
[0036]
At the time of recording, the video signal processing unit 3 performs compression processing on the digital image signal supplied from the camera block 2 and the digital audio signal obtained by collecting the sound with the microphone 202, and converts the compressed data into user recording data. To the media drive unit 4 in the subsequent stage. Further, an image generated from the digital image signal and the character image supplied from the camera block 2 is supplied to the viewfinder drive unit 207 and displayed on the viewfinder 204.
Further, at the time of reproduction, user reproduction data (read data from the disk 51) supplied from the media drive unit 4, that is, compressed image signal data and audio signal data are demodulated, and these are reproduced as reproduced image signals. And output as a playback audio signal.
[0037]
In this example, MPEG (Moving Picture Experts Group) 2 is used for moving images and JPEG (Joint Photographic Coding Experts Group) is used for still images as compression / decompression processing methods for image signal data (image data). It shall be adopted. Further, it is assumed that ATRAC (Adaptve Transform Acoustic Coding) 2 is adopted as the audio signal data compression / decompression processing method.
[0038]
The data processing / system control circuit 31 of the video signal processing unit 3 mainly performs control processing relating to compression / decompression processing of image signal data and audio signal data in the video signal processing unit 3 and data passing through the video signal processing unit 3. Executes the process to control the input / output.
The video controller 38 executes control processing for the entire video signal processing unit 3 including the data processing / system control circuit 31. The video controller 38 includes, for example, a microcomputer, and can communicate with the camera controller 25 of the camera block 2 and a driver controller 46 of the media drive unit 4 described later via, for example, a bus line (not shown). Has been.
[0039]
As a basic operation during recording in the video signal processing unit 3, the image signal data supplied from the video A / D converter 23 of the camera block 2 is input to the data processing / system control circuit 31. The data processing / system control circuit 31 supplies the input image signal data to the motion detection circuit 35, for example. The motion detection circuit 35 performs image processing such as motion compensation on the input image signal data while using the memory 36 as a work area, for example, and then supplies the processed image signal data to the MPEG2 video signal processing circuit 33.
[0040]
In the MPEG2 video signal processing circuit 33, for example, the input image signal data is subjected to compression processing according to the MPEG2 format while using the memory 34 as a work area, and a compressed data bitstream (MPEG2 bitstream) as a moving image is applied. Is output. In the MPEG2 video signal processing circuit 33, for example, when image data as a still image is extracted from image signal data as a moving image and subjected to compression processing, compressed image data as a still image according to the JPEG format. Is configured to generate It is also conceivable that an I picture (Intra Picture), which is regular image data, is handled as still image data without using JPEG as compressed image data in the MPEG2 format.
The image signal data (compressed image data) compressed and encoded by the MPEG2 video signal processing circuit 33 is written and temporarily stored in the buffer memory 32 at a predetermined transfer rate, for example.
As is well known, the MPEG2 format supports both a constant speed (CBR) and a variable speed (VBR) as the so-called encoding bit rate (data rate). The video signal processing unit 3 can cope with these.
[0041]
For example, when image compression processing by VBR is performed, for example, if the motion detection circuit 35 detects motion in a range of several tens to several hundred frames before and after the image data in units of macroblocks, This detection result is transmitted to the MPEG2 video signal processing circuit 33 as motion vector information.
In the MPEG2 video signal processing circuit 33, the quantization coefficient for each macroblock is calculated while using the necessary information including the motion vector information so that the image data after compression coding has a certain required data rate. It will be decided.
[0042]
The audio collected by the microphone 202, for example, is input to the audio compression encoder / decoder 37 as digital audio signal data via the A / D converter 64 (in the display / image / audio input / output unit 6).
The audio compression encoder / decoder 37 performs compression processing on the audio signal data input according to the ATRAC2 format as described above. The compressed audio signal data is also written into the buffer memory 32 by the data processing / system control circuit 31 at a predetermined transfer rate, and is temporarily held here.
[0043]
As described above, the compressed image data and the compressed audio signal data can be stored in the buffer memory 32. The buffer memory 32 mainly absorbs the speed difference between the data transfer rate between the camera block 2 or the display / image / audio input / output unit 6 and the buffer memory 32 and the data transfer rate between the buffer memory 32 and the media drive unit 4. Has a function for.
The compressed image data and compressed audio signal data stored in the buffer memory 32 are sequentially read at a predetermined timing and transmitted to the MD-DATA2 encoder / decoder 41 of the media drive unit 4 when recording. However, for example, reading of data stored in the buffer memory 32 at the time of reproduction and operations until the read data is recorded on the disk 51 through the deck unit 5 from the media drive unit 4 are performed intermittently. It doesn't matter.
Such data writing and reading control with respect to the buffer memory 32 is executed by, for example, the data processing / system control circuit 31.
[0044]
The operation during reproduction in the video signal processing unit 3 is roughly as follows.
During reproduction, compressed image data and compressed audio signal data (user reproduction data) read from the disk 51 and decoded in accordance with the MD-DATA2 format by processing of the MD-DATA2 encoder / decoder 41 (in the media drive unit 4) It is transmitted to the data processing / system control circuit 31.
In the data processing / system control circuit 31, for example, the input compressed image data and compressed audio signal data are temporarily stored in the buffer memory 32. Then, for example, the compressed image data and the compressed audio signal data are read from the buffer memory 32 at a required timing and transfer rate so that the reproduction time axis can be matched, and the MPEG2 video signal processing circuit is used for the compressed image data. The compressed audio signal data is supplied to the audio compression encoder / decoder 37.
[0045]
In the MPEG2 video signal processing circuit 33, the input compressed image data is expanded and transmitted to the data processing / system control circuit 31. The data processing / system control circuit 31 supplies the decompressed image signal data to the video D / A converter 61 (inside the display / image / audio input / output unit 6).
The audio compression encoder / decoder 37 performs an expansion process on the input compressed audio signal data and supplies it to the D / A converter 65 (in the display / image / audio input / output unit 6).
[0046]
In the display / image / audio input / output unit 6, the image signal data input to the video D / A converter 61 is converted into an analog image signal here and branched to the display controller 62 and the composite signal processing circuit 63. Is input.
The display controller 62 drives the display unit 6A based on the input image signal. As a result, the reproduced image is displayed on the display unit 6A. Further, in the display unit 6A, not only the display of the image obtained by reproducing from the disc 51, but of course, the captured image obtained by photographing with the camera part composed of the lens block 1 and the camera block 2, It is possible to display and output in almost real time.
In addition to the reproduced image and the captured image, as described above, a message display using characters, characters, or the like for notifying the user of a required message according to the operation of the device is also performed. Such a message display should be output from the data processing / system control circuit 31 to the video D / A converter 61 so that a required character, character, or the like is displayed at a predetermined position under the control of the video controller 38, for example. What is necessary is just to perform the process which synthesize | combines image signal data, such as a required character and a character, with respect to image signal data. That is, in this example, the video controller 38 and the data processing / system control circuit 31 have functions of a character generator and an on-screen display.
[0047]
The composite signal processing circuit 63 converts the analog image signal supplied from the video D / A converter 61 into a composite signal and outputs it to the video output terminal T1. For example, if an external monitor device or the like is connected via the video output terminal T1, an image reproduced by the video camera can be displayed on the external monitor device.
[0048]
In the display / image / audio input / output unit 6, the audio signal data input from the audio compression encoder / decoder 37 to the D / A converter 65 is converted into an analog audio signal here, and is output to the headphone / line terminal T2. Is output. Further, the analog audio signal output from the D / A converter 65 is also branched and output to the speaker SP via the amplifier 66, whereby reproduced audio or the like is output from the speaker SP. Become.
[0049]
In the media drive unit 4, the recording data is encoded in conformity with the MD-DATA2 format at the time of recording and transmitted to the deck unit 5 in conformity with the disk recording, and is read from the disk 51 in the deck unit 5 at the time of reproduction. The decoded data is subjected to decoding processing to obtain reproduced data, which is transmitted to the video signal processing unit 3.
[0050]
The MD-DATA2 encoder / decoder 41 of the media drive unit 4 receives recording data (compressed image data + compressed audio signal data) from the data processing / system control circuit 31 during recording. A predetermined encoding process according to the DATA2 format is performed and the encoded data is stored in the temporary buffer memory 42. Then, the data is transmitted to the deck unit 5 while being read out at a required timing.
[0051]
At the time of reproduction, the digital reproduction signal read from the disc 51 and inputted through the RF signal processing circuit 44 and the binarization circuit 43 is subjected to decoding processing in accordance with the MD-DATA2 format to obtain reproduction data. The data is transmitted to the data processing / system control circuit 31 of the video signal processing unit 3.
Also in this case, if necessary, the reproduction data is temporarily stored in the buffer memory 42, and the data read therefrom at a required timing is transmitted and output to the data processing / system control circuit 31. Such write / read control for the buffer memory 42 is executed by the driver controller 46.
It should be noted that, for example, even when the servo is disconnected due to a disturbance or the like during playback of the disk 51 and reading of the signal from the disk becomes impossible, the read data is stored in the buffer memory 42 within the period. If the playback operation on the disc is restored, it is possible to maintain time-series continuity as the playback data.
[0052]
The RF signal processing circuit 44 performs necessary processing on the read signal from the disk 51, for example, an RF signal as reproduction data, a focus error signal for servo control for the deck unit 5, a tracking error signal, and the like. Servo control signal is generated. The RF signal is binarized by the binarization circuit 43 as described above, and is input to the MD-DATA2 encoder / decoder 41 as digital signal data.
The generated servo control signals are supplied to the servo circuit 45. The servo circuit 45 executes necessary servo control in the deck unit 5 based on the input servo control signal.

In this example, an encoder / decoder 47 corresponding to the MD-DATA1 format is provided, and the recording data supplied from the video signal processing unit 3 is encoded according to the MD-DATA1 format and recorded on the disc 51. Alternatively, the data read from the disk 51 is encoded according to the MD-DATA1 format, and can be decoded and transmitted to the video signal processing unit 3. That is, the video camera of this example is configured to be compatible with the MD-DATA2 format and the MD-DATA1 format.
The driver controller 46 is a functional circuit unit for controlling the media drive unit 4 as a whole.
[0054]

Although not shown here, the deck unit 5 has a mechanism (disk slot 203 (see FIG. 6)) in which the disk 51 to be loaded is detachable and can be replaced by the user's work. It is supposed to be. The disk 51 here is premised on a magneto-optical disk corresponding to the MD-DATA2 format or the MD-DATA1 format.
[0055]
In the deck unit 5, the loaded disk 51 is rotationally driven by CLV by a spindle motor 52 that rotationally drives the disk 51 by CLV. The disc 51 is irradiated with laser light from the optical head 53 during recording / reproduction.
The optical head 53 performs high-level laser output for heating the recording track to the Curie temperature during recording, and relatively low-level laser output for detecting data from reflected light by the magnetic Kerr effect during reproduction. . Therefore, although not shown in detail here, the optical head 53 is equipped with a laser diode as a laser output means, an optical system including a polarizing beam splitter, an objective lens, and the like, and a detector for detecting reflected light. Yes. The objective lens provided in the optical head 53 is held so as to be displaceable in a disk radial direction and a direction in which it is in contact with and separated from the disk, for example, by a biaxial mechanism.

Although not shown, the deck unit 5 is provided with a thread mechanism that is driven by a thread motor 55. By driving the sled mechanism, the entire optical head 53 and the magnetic head 54 are movable in the disk radial direction.
[0057]
The operation unit 7 corresponds to each of the operators 300 to 311 shown in FIG. 6, and various types of user operation information by these operators are supplied to the video controller 38, for example. The video controller 38 supplies the camera controller 25 and the driver controller 46 with operation information and control information for allowing each unit to execute necessary operations according to user operations.
[0058]
The external interface 8 is provided so that data can be transmitted between the video camera and the external device.

Information (photocurrent obtained by detecting the laser reflected light by the photodetector) detected by the data reading operation of the optical head 53 with respect to the disk 51 is supplied to the RF amplifier 101 in the RF signal processing circuit 44.
The RF amplifier 101 generates a reproduction RF signal as a reproduction signal from the input detection information and supplies it to the binarization circuit 43. The binarization circuit 43 performs binarization on the input reproduction RF signal, thereby obtaining a reproduction RF signal (binarization RF signal) converted into a digital signal.
The binarized RF signal is supplied to the MD-DATA2 encoder / decoder 41. First, gain adjustment, clamp processing, and the like are performed via the AGC / clamp circuit 103, and then input to the equalizer / PLL circuit 104.
The equalizer / PLL circuit 104 performs equalizing processing on the input binarized RF signal and outputs the result to the Viterbi decoder 105. Further, by inputting the binarized RF signal after the equalizing process to the PLL circuit, the clock CLK synchronized with the binarized RF signal (RLL (1, 7) code string) is extracted.
[0062]
The frequency of the clock CLK corresponds to the current disk rotation speed. Therefore, the CLV processor 111 receives the clock CLK from the equalizer / PLL circuit 104 and obtains error information by comparing it with a reference value corresponding to a predetermined CLV speed (see FIG. 3). This is used as a signal component for generating the error signal SPE. The clock CLK is used as a clock for processing in a required signal processing circuit system including the RLL (1, 7) demodulation circuit 106, for example.
[0063]
The Viterbi decoder 105 performs a decoding process according to a so-called Viterbi decoding method on the binarized RF signal input from the equalizer / PLL circuit 104. As a result, reproduction data as an RLL (1, 7) code string is obtained.
This reproduced data is input to the RLL (1, 7) demodulating circuit 106, where the data stream is subjected to RLL (1, 7) demodulation.
[0064]
The data stream obtained by the demodulation processing in the RLL (1, 7) demodulation circuit 106 is written to the buffer memory 42 via the data bus 114 and developed on the buffer memory 42.
The data stream developed on the buffer memory 42 is first subjected to error correction processing in units of error correction blocks according to the RS-PC system by the ECC processing circuit 116, and further descramble / EDC. The decoding circuit 117 performs descrambling processing and EDC decoding processing (error detection processing).
The data that has been processed so far is used as reproduction data DATAp. The reproduction data DATAp is transferred from the descramble / EDC decode circuit 117 to the data processing / system control circuit 31 of the video signal processing unit 3 at a transfer rate according to the transfer clock generated by the transfer clock generation circuit 121, for example. Will be transmitted.
[0065]
For example, the transfer clock generation circuit 121 appropriately transmits a crystal clock when performing data transmission between the media drive unit 4 and the video signal processing unit 3 and data transmission between functional circuit units in the media drive unit 4. It is a part for generating a transfer clock (data transfer rate) having an appropriate frequency.
Further, a clock having a required frequency to be supplied to each functional circuit unit of the media drive unit 4 and the video signal processing unit 3 is generated according to the operation state of the video camera.
[0066]
Detection information (photocurrent) read from the disk 51 by the optical head 53 is also supplied to the matrix amplifier 107.
In the matrix amplifier 107, necessary detection processing is performed on the input detection information, whereby a tracking error signal TE, a focus error signal FE, and groove information (absolute address information recorded as a wobbled groove WG on the disk 51) GFM. Are extracted and supplied to the servo circuit 45. That is, the extracted tracking error signal TE and focus error signal FE are supplied to the servo processor 112, and the groove information GFM is supplied to the ADIP band pass filter 108.
[0067]
The groove information GFM band-limited by the ADIP bandpass filter 108 is supplied to the A / B track detection circuit 109, the ADIP decoder 110, and the CLV processor 111.
In the A / B track detection circuit 109, for example, based on the method described with reference to FIG. 2B, the currently tracked track is selected from the track TR · A and TR · B based on the input groove information GFM. The track discrimination information is output to the driver controller 46. The ADIP decoder 110 decodes the input groove information GFM to extract an ADIP signal that is absolute address information on the disk and outputs the ADIP signal to the driver controller 46. The driver controller 46 executes necessary control processing based on the track discrimination information and the ADIP signal.
[0068]
The CLV processor 111 receives the clock CLK from the equalizer / PLL circuit 104 and the groove information GFM via the ADIP bandpass filter 108. The CLV processor 111 generates a spindle error signal SPE for CLV servo control based on, for example, an error signal obtained by integrating a phase error with the clock CLK with respect to the groove information GFM, and outputs the spindle error signal SPE to the servo processor 112. The required operation to be executed by the CLV processor 111 is controlled by the driver controller 46.
[0069]
The servo processor 112 performs various servo control signals (tracking control) based on the tracking error signal TE, the focus error signal FE, the spindle error signal SPE, the track jump command from the driver controller 46, the access command, etc. input as described above. Signal, focus control signal, thread control signal, spindle control signal, etc.) are generated and output to the servo driver 113.
The servo driver 113 generates a required servo drive signal based on the servo control signal supplied from the servo processor 112. The servo drive signal here includes a biaxial drive signal for driving the biaxial mechanism (two types of focus direction and tracking direction), a sled motor drive signal for driving the sled mechanism, and a spindle motor drive signal for driving the spindle motor 52. It becomes.
By supplying such a servo drive signal to the deck unit 5, focus control and tracking control for the disk 51 and CLV control for the spindle motor 52 are performed.
[0070]
When a recording operation is performed on the disc 51, for example, the recording data DATAAr is input from the data processing / system control circuit 31 of the video signal processing unit 3 to the scramble / EDC encoding circuit 115. . The user recording data DATAr is input in synchronization with a transfer clock (data transfer rate) generated by the transfer clock generation circuit 121, for example.
[0071]
In the scramble / EDC encode circuit 115, for example, the recording data DATAAr is written and expanded in the buffer memory 42, and data scramble processing and EDC encoding processing (error detection code addition processing by a predetermined method) are performed. After this processing, for example, the ECC processing circuit 116 adds an RS-PC error correction code to the recording data DATAAr developed in the buffer memory 42.
The recording data DATAr that has been processed so far is read from the buffer memory 42 and supplied to the RLL (1, 7) modulation circuit 118 via the data bus 114.
[0072]
The RLL (1, 7) modulation circuit 118 performs RLL (1, 7) modulation processing on the input recording data DATAAr, and outputs the recording data as the RLL (1, 7) code string to the magnetic head driving circuit 119. To do.
[0073]
By the way, in the MD-DATA2 format, a so-called laser strobe magnetic field modulation method is adopted as a recording method for the disk. The laser strobe magnetic field modulation method is a recording method in which a magnetic field modulated by recording data is applied to a disk recording surface, and laser light to be irradiated onto the disk is pulsed in synchronization with the recording data.
In such a laser strobe magnetic field modulation method, the formation process of the pit edge recorded on the disc does not depend on the transient characteristics such as the magnetic field reversal speed and is determined by the irradiation timing of the laser pulse.
Therefore, for example, compared with a simple magnetic field modulation method (a method in which a laser beam is constantly irradiated onto a disk and a magnetic field modulated by recording data is applied to a disk recording surface), a laser strobe magnetic field modulation method is used. In this case, it is possible to easily reduce the jitter of the recording pit. That is, the laser strobe magnetic field modulation method is an advantageous recording method for high density recording.
[0074]
The magnetic head drive circuit 119 of the media drive unit 4 operates so that a magnetic field modulated by the input recording data is applied from the magnetic head 54 to the disk 51. Further, a clock synchronized with the recording data is output from the RLL (1, 7) modulation circuit 118 to the laser driver 120. Based on the input clock, the laser driver 120 drives the laser diode of the optical head 53 so that a laser pulse synchronized with recording data generated as a magnetic field by the magnetic head 54 is irradiated to the disk. . At this time, the laser pulse emitted from the laser diode is based on the required laser power suitable for recording. In this way, the recording operation as the laser strobe magnetic field modulation method is enabled by the media drive unit 4 of this example.
[0075]
5). Example of disk structure corresponding to this embodiment
Next, a structural example of the disk 51 corresponding to this embodiment will be described.
FIG. 7 conceptually shows a structural example of the disk 51 corresponding to the present embodiment. The physical format of the disk 51 shown in this figure is as described above with reference to FIGS.
[0076]
In the disk 51, for example, PTOC and RTOC areas are provided as management information areas. In the PTOC, for example, in the pre-mastered area (pit area) on the innermost periphery of the disc, necessary management information is recorded according to the pit form. The contents of this PTOC cannot be rewritten.
For example, a magneto-optical recording area in which magneto-optical recording / reproduction is possible is formed on the outer periphery of the pre-mastered area where the PTOC is recorded. First, the RTOC region is provided for a section of a predetermined size in the innermost circumference. In this RTOC, for example, basic information necessary for managing data recorded on a disc is recorded.
For example, in the case of this example, tracks (which may be synonymous with files) and folders (a structure for grouping and managing tracks), which will be described later, are managed as data recorded on the disc at the time of recording and reproduction. Information for storing is stored.
Note that the contents of the U-TOC in the management area are sequentially rewritten in accordance with, for example, data recording results to date and editing processing results such as deletion of tracks (files) and folders.
[0077]
A data area for recording user data is provided on the outer peripheral side of the RTOC. In the present embodiment, this data area is managed as a volume folder (Volume Folder) placed in one root folder. In the present embodiment, a volume is defined as a complete set of user data, and is defined as having only one volume on one disk. The data contained in this volume is stored as folders and tracks below the volume folder, except for data managed by the PTOC and RTOC.
[0078]
In the volume folder, first, a volume index track (Volume Index Track) of a predetermined size (for example, 12 clusters) is placed at a physically innermost position (management track priority area near the RTOC).
For example, if the PTOC and RTOC are the main management information, the volume index track is defined as an area in which the sub management information is recorded. The track index file is a track (file), a folder, and auxiliary data (Auxiliary Data). And a table in which information for managing the property, title, and packet data forming the track is recorded.
[0079]
In addition, as a track recorded so that at least the first cluster is located in the management track priority area near the RTOC, a thumbnail track (Thumbnail
Picture Track) can be placed as an option.
In this embodiment, it is possible to have one still image reduced by a predetermined resolution as a thumbnail image in association with each file recorded on the disc. The thumbnail image is handled as a representative image for making the file visually recognizable.
The thumbnail track is recorded with index information indicating the association with the file (track) recorded on the disc and the storage position of the thumbnail image. The data length of the thumbnail track can be arbitrarily expanded according to the number of thumbnail images stored.
[0080]
For example, image / sound data recorded by a user by shooting or the like is managed in units of files, and is placed in a volume folder as a track under a volume folder or in a folder under a volume folder. become. In the disc of this embodiment, in addition to moving image data, still image data, audio data, text files such as documents can be stored as files (tracks).
FIG. 7 shows a state in which a certain file is expressed as one track and this track is stored in a certain folder. As described above, the folder is a structure for managing tracks or folders in a group.
Therefore, in the structure below the volume folder, an arbitrary number of tracks or folders are stored within a range defined by the maximum number of items that can be stored in the volume folder and the maximum number of levels of the hierarchical structure of the folder.
[0081]
In the volume folder, an auxiliary data track (Auxiliary Data Track) storing auxiliary data (Auxiliary Data) is arranged.
The information to be stored in the auxiliary data track is arbitrary depending on, for example, the application that is actually applied.
In the present embodiment, script information as reproduction control information is stored.
[0082]
By the way, the information stored in the PTOC, RTOC, or even the volume index track, which is the above-described management information (these information are collectively referred to as “management information” in the present embodiment) is, for example, When the disc is loaded, it is read out and held in a predetermined area of the buffer memory 42 (or buffer memory 32) of the media drive unit 4, for example. At the time of data recording and editing, the management information held in the buffer memory is rewritten according to the recording result and the editing result, and then the buffer memory is stored at a predetermined opportunity and timing. Based on the contents of the held management information, the management information of the disk 51 is rewritten (updated) (however, the PTOC is not updated).
[0083]
It should be noted that the example of the disk structure shown in this figure is merely an example, and the physical positional relationship of each area on the disk may be changed according to actual use conditions and the structure for storing data. It may be changed.
[0084]
6). Thumbnail image generation processing
The thumbnail images stored in the thumbnail track shown in FIG. 7 can be generated by the video camera of the present embodiment. Here, the thumbnail image generation processing will be described. Here, a case where a thumbnail image for an image file once recorded on the disc is generated will be described.
[0085]
As described above, for example, the management information (PTOC, RTOC, volume index track) recorded on the disk 51 is read at a predetermined timing such as when the disk is loaded, and stored in the buffer memory 42 (or the buffer memory 32). It is assumed that they are stored.
[0086]
Then, the driver controller 46 refers to the management information stored in the buffer memory 42, for example, on the disk on which the image data designated as the thumbnail image is recorded for the file from which the thumbnail image is to be generated. The image data as the thumbnail image generation source is obtained by accessing the address and causing the disk to perform a read operation.
The image data is sequentially transmitted from the media drive unit 4 to the video signal processing unit 3 and supplied to the data processing / system control circuit 31.
Note that the image data defined as the thumbnail image generation source by the management information is, for example, the first frame (or field) image data in the file, unless otherwise specified.
[0087]
Then, the data processing / system control circuit 31 first controls the MPEG2 video signal processing circuit 33 to perform the expansion processing according to the MPEG2 format with respect to the supplied screen data to the level of the image data in the field image unit. The decoded data is acquired.
[0088]
For example, in the stage of the image data decoded to the level of the field image unit, the data is usually data having an image size (number of pixels) that can be displayed almost at full size on the display screen.
Therefore, after the full-size image data in the field image unit is obtained, the full-size image data is reduced so that the actually required thumbnail image size is obtained. It will be.
In order to reduce the image size, for example, the original full-size image data is sampled at appropriate timing with respect to the pixel data, and the signal is used to reconstruct the image data based on the sampled pixel data. What is necessary is just to perform a process.
[0089]
Then, for example, the video controller 38 generates index information (described with reference to FIG. 7) for the thumbnail image data obtained in this way, and records the thumbnail image data together with the index information on the thumbnail track of the disc. Execute control.
In this way, thumbnail image data corresponding to each file is obtained and recorded on the disc.
[0090]
In this embodiment, as can be understood from the above description, in addition to image data (including audio data), audio data based only on audio, and character information data can be recorded as a file. For example, when there is no image data as a thumbnail image generation source in the file, such as voice data and character information data, for example, it can be visually recognized in advance as voice data or character information data. Image data of such a pattern is prepared (for example, stored in the ROM of the video controller 38 or stored in a predetermined area of the disk), and this image data is used as a thumbnail image. This is what you should do.
[0091]
7). Script overview
Further, in the present embodiment, editing processing such as designation of reproduction order and giving a required special effect at the time of reproduction can be performed on a file (mainly a recorded file) recorded by the video camera.
In performing the editing as described above, in this embodiment, a script as reproduction control information capable of giving a required reproduction output mode for a recorded file is prepared. By interpreting the script, a reproduction output mode (for example, reproduction order) corresponding to the editing result is obtained. In the editing stage, the editing process is executed by updating the contents of the script. The “script” here refers to a procedure writing structure described in a predetermined program language for reproducing and outputting moving image data, still image data, audio data, and document data at the same time. It is supposed to be.
[0092]
First of all, a script used as reproduction control information in this embodiment will be schematically described.
[0093]
In the present embodiment, as a script, SMIL (Synchronized Multimedia
Integration Language) shall be adopted.
SMIL is a language that is standardized by W3C (Internet standardization organization) to realize, for example, television program broadcasts and presentations on the Internet, and is based on the grammar of XML (superset of HTML). It is intended to realize time-series presentations.
[0094]
First, scheduling is expressed by two tags <seq> and <par>.
<Seq> means “sequential”, that is, serial, and information surrounded by the tags is reproduced in time order.
<Par> means parallel, that is, parallel, and the information enclosed by the tags is reproduced synchronously.
[0095]
Here, for example, in the file recorded on the disc, when it is specified that the image data files represented as video1, video2, and video3 are reproduced in the order of video1 → video2 → video3,

The description is as follows.
[0096]
Also, when the file video1 → video2 → video3 is reproduced in the order, and the audio1 audio1 file is desired to be simultaneously reproduced as an after-record track for the video1,

The description is performed as follows.
[0097]
Also, a description is provided for designating that a file to be reproduced in synchronization with a certain file is to be reproduced from a position after a certain number of seconds after the certain file is reproduced.
For example, when a caption (for example, an image as character information) is displayed 5 seconds after a video1 image file is displayed (reproduced),

The description is performed as follows.
[0098]
For example, if an instruction is given to display the file picture1 as a still image file for 5 seconds,
<Image src = “picture1” dur = “5s”>
It is described as follows.
[0099]
Also, so-called frame mute is used, and “range” is used when reproducing a part of a certain moving image file. For example, assuming that the standard of SMPTE (Society of Motion Picture and Television) is adopted as the time code,
<Video src = "video1" range = "smpte: 10: 07: 00-10: 007: 33">
It can be described as follows.
[0100]
In addition, “repeat” is used to designate a certain file and repeat. For example, if you want to repeat a video1 file 10 times,
<Video src = “video1” repeat = “10”>
Describe as follows.
[0101]
In this embodiment, such a script called SMIL is used so that display control for giving a required display form as a thumbnail display can be executed.
Therefore, for example, in the video camera system of the present embodiment, a subset of XML is prepared so that interpretation corresponding to this SMIL and script description (generation) can be performed. For example, this may be stored in advance in a ROM or the like in the video controller 38 as a program to be executed by the video controller 38, or may be recorded on the application layer of the disc so that it can be read out.
[0102]
In the present embodiment, such a script is generated or updated by the video controller 38 in, for example, an editing stage (or a recording operation stage) and held in a predetermined area in the buffer memory 32, for example. It is supposed to be kept.
The script held in the buffer memory 32 in this way is recorded on the disk at a predetermined opportunity or timing. The script data is stored as a script file for the auxiliary data track described with reference to FIG. Since the script is recorded on the disk in this way, the next time the disk is newly loaded, the script recorded on the disk is read and stored in, for example, the buffer memory 32 and referenced. Thus, editing and reproduction can be performed in accordance with the reproduction order obtained by the previous editing.
[0103]
8). Function for creating a video work in this embodiment
8-1. Overview
Next, the video work creation function (editing function) of this embodiment will be described. An editing application program (an input instruction program and an editing program) is prepared for the video work creation function of the present embodiment. The application program for editing is a program for editing a video work of a specific genre, and creates a video work according to a preset script.
Specifically, first, when shooting a source (recording file) that is a material of a video work, a GUI as a guide function is displayed based on the above script, so that an input operation required for the user is appropriately performed. And urged to shoot. Information (including character information) obtained by an input operation performed in accordance with this GUI and a recording file (image / audio data file) obtained by photographing are handled as editing material information.
As an actual editing process, a video work is created by performing editing using the editing material information according to the script structure. However, in the present embodiment, in the editing process, the recorded recording file is not directly subjected to the editing process, but the recording file playback order and various editing effects (for example, superimpose and BGM are inserted by the script described above). The video camera interprets the script and performs appropriate signal processing to perform editing and reproduction.
[0104]
In the present embodiment, the editing application program is recorded as one file (track) on the disc. A file recorded by the guide function of the editing application program and a script file are also recorded on the same disk.
In other words, in this embodiment, an editing application program for a video work in accordance with a specific purpose is recorded on a disk, and data and scripts as materials necessary for the editing can be recorded. Thus, a disc specialized for creating and reproducing a video work of this specific genre is provided.
As for the application program for editing, for example, a non-volatile memory may be provided on the video camera side and stored in the non-volatile memory. That is, it is conceivable that the video camera itself is configured to have a function for creating a video work of a specific genre.
[0105]
8-2. Information input and shooting according to the guide function
Therefore, hereinafter, the process of creating a video work in the present embodiment will be described along one specific example.
Here, a case where a golf competition pattern is created as a video work is taken as an example. Therefore, the user in this case prepares a disc specialized to create a video work for a golf competition in which an editing program for a golf competition is recorded.
Here, a case where three users, Mr. A, Mr. B, and Mr. C, perform a golf competition is taken as an example. Hereinafter, the term “user” refers to a person who handles the video camera among at least one of Mr. A, Mr. B, and Mr. C.
[0106]
First, with reference to FIGS. 8 to 10, an example of a procedure in which a user performs information input for editing (operation information input and editing material shooting) while performing a golf competition will be described. In the following description, programs corresponding to input operations and the like are sequentially shown as necessary. This program is equipped with a system that enables the master controller (video controller 38) of the video camera to understand the JAVA language. It is a program when it corresponds to the configuration. Therefore, the variable definition and class definition in this example in this program are shown here first.

Variable list
int numberofparty; // number of parties
String course; // name of the course
Party party []; // Information of members for the number of parties
Track track []; //
Hole hole []; // Information on this course (18 holes)
[0107]
For example, a user (Mr. A, Mr. B, and Ms. C) can use the video camera of the present embodiment and the disc of the present embodiment specialized for creating a golf competition video work (hereinafter simply referred to as “golf disc”). ) And go to the target golf course.
Then, for example, at a stage before rounding the course at a golf course, a golf disc is loaded into the video camera, and the guide function display of the editing application program recorded on the disc is operated by a predetermined operation. As an operation for this, for example, an editing program is selected and reproduced in accordance with a predetermined operation procedure for normal file reproduction. As a result, the editing program is started. For example, the editing program menu screen is displayed first. Then, the user operates the menu screen to call up the guide function display.
[0108]
Thus, for example, the guide display shown in FIG. 8 is performed on the display unit 6A according to the editing program. The guide display shown in FIG. 8 is used to input various information necessary for editing before the round.
[0109]
Here, as a guide display for preparatory input before the round, first, the display shown in FIG. 8A is performed. The guide display in FIG. 8A is for inputting the number of people who round the course. In this case, since there are three people, the user performs an operation to input that there are three people on this N screen. As the operation procedure at this time, for example, buttons “2”, “3”, “4”, “5” and an input window of “more” are displayed. The click key 310 is operated to place a cursor (not shown) on the “three people” button, and in this state, a click operation is performed on the center portion of the cross / click key 310. In other words, the “three people” button is selected and a click operation is performed. Thereby, information that the number of people who round is three is input. As a program corresponding to this input operation, for example,
number of parity = 3;
become that way.
The description of such a program, which will be shown later, needs to be saved in order to be used for creating a script to be described later. For example, the program description is sequentially recorded in a predetermined directory on the disk. What is necessary is just to comprise. Alternatively, it may be possible to store and store the data in a predetermined area of a memory (for example, the buffer memory 42) inside the video camera.
[0110]
When the input operation with respect to the guide display in FIG. 8A is finished and, for example, a click operation is performed on the button displayed as “Next”, the display is switched to the guide display shown in FIG.
The guide display in FIG. 8B prompts photographing of a scene where each member talks about his aspirations. For example, here, the current captured image (the image signal currently obtained by the lens block 1 and the camera block 2) is displayed, and then “the first person's aspiration today is about 5 seconds. “Please take a picture with”, and so on, a character display (superimpose) that prompts the member who speaks of aspiration to shoot and an impose display of a “shooting frame” that specifies the composition of the member who is the subject. This “shooting designation frame” is displayed for designating an ideal composition for a subject as a variant material, and is not displayed during actual editing / playback (the same is true for the character display). While monitoring the display unit 6A on which this display is being performed, the user can take a picture of one member who talks about his aspirations in about 5 seconds with a composition in which the member almost fits in the designated shooting frame. The
The recorded video file (moving image / audio file) captured here is saved by being recorded on a disk with, for example, video1 and a file name,
party [0]. begincomment = video1;
In such a form, association is made that the comment is the comment before the first round.
[0111]
Here, when shooting of one member is finished, the display shown in FIG. 8C is performed as a guide display. That is, it is asked whether or not the video that has just been taken is satisfactory to the user. At this stage, you can play back and check the image you just shot by clicking on the “Review” button. If the result is not satisfactory, click on the “Review” button. By the operation, photographing in the guide display state shown in FIG. 8B can be resumed. Here, if the captured image is satisfactory to the user as a result, the guide display of FIG. 8C is exited by a predetermined operation and the guide display shown in FIG.
[0112]
In the guide display shown in FIG. 8 (d), as information about the member who has just photographed, characters can be input to items that are actually prepared as input items such as name and handy. . In the present embodiment, characters can be input using the jog dial 311 shown in FIG. In this guide display, it is assumed that the member's face photo is displayed. This face photo image is obtained by generating a thumbnail image from image data of a file that records a scene in which an aspiration was previously made. Such processing is automatically executed by the editing program.
Then, when the character input for the necessary items is completed, for example, a click operation on the “OK” button is performed. At this time, as a program, for example, if the character input for the first member photographed is performed,
party [0]. name = “Mr. A”;
party [0]. handycap = 20;
In this way, the member's name and handicap are registered.
[0113]
Here, the guide display is shifted to when the click operation on the “OK” button is performed, but if the shooting of the scene to talk about the aspirations of all the members has not been completed, the process returns to FIG. To be. In this case, since there are three members, the user repeats the procedure described in FIG. 8B → FIG. 8C → FIG. 8D three times. In this way, when the shooting of the scene to talk about the aspirations of all members is completed, as a program,
party [1]. begincomment = video2;
party [2]. begincomment = video3;
In this way, the recorded files that talk about the aspirations of the second and third members are registered as video2 and video3, and by inputting characters for the second and third members on the guide display in FIG. ,
party [1]. name = “Mr. B”;
party [1]. handycap = 8;
party [2]. name = “Mr. C”;
party [2]. handycap = 15;
Association is performed as follows.
[0114]
As described above, after the procedure described with reference to FIG. 8B → FIG. 8C → FIG. 8D is repeated for all the members, the “OK” button shown in FIG. 8D is operated. If it is, the guide display in FIG.
[0115]
In the guide display of FIG. 8 (e), a course to be rounded is selected.
For this reason, in the guide display shown in FIG.8 (e), the candidate of the course of a golf course is displayed. The course of the golf course displayed as a candidate here is assumed to be stored as a database in the editing program. In this database, for example, the number of holes for each course, the number of yards (distance) for each hole, Information such as the number of pars is stored.
On the guide display shown in FIG. 8E, the user operates the cross / click key 310, for example, to select a course of the golf course to be rounded and perform a click operation (decision operation). Here, “柏 country club” is selected and determined as the course of the golf course.
Thereby, as a program,
course = “柏 Country Club”;
Registration is performed as described above.
[0116]
As described above, this editing program has a database of courses. In this case, when the 柏 Country Club is registered as described above, the total length, par Data such as numbers can be accessed. About these databases, as a program,
hole [? ]. par
hole [? ]. length
Can be accessed from variables such as
When the input operation up to course selection (FIG. 8E) is completed as described above, in this case, for example, as shown in the guide display of FIG. A telop such as “Preparation is complete” is displayed so that the user is informed that all input operations as preparation before the round have been completed.
[0117]
Subsequently, a guide display during a round and a user procedure according to the guide display will be described with reference to FIGS. 9 and 10.
For example, after the input operation shown in FIG. 8 is completed, a guide display as shown in FIG. 9A is performed, and an instruction is given to take a tee shot of the first hole. Then, in the subsequent guide display of FIG. 9B, an operation for selecting a member to be a subject is prompted. Also, in the guide display of FIG. 9B, the face photograph of each member is displayed by using the thumbnail image generated from the image data of the file in which the scene where the aspiration was told is recorded. Then, the selection decision operation is performed by moving the cursor with respect to the face photograph of each member.
[0118]
When the selection determination operation is performed on the guide display shown in FIG. 9B, the display unit 6A becomes the guide display shown in FIG. 9C. For example, the current captured image is captured in about 5 seconds. The instruction of the imaging time by the superimpose “Please do” and an imaging instruction frame for designating the composition are displayed. In this state, the user takes an image of the player performing a tee shot (performs a recording operation). Also in this case, when the recording operation is ended, the guide display in which the “review”, “recover”, and “OK” buttons are displayed as shown in FIG. This is the same as in the case of shooting according to the procedure of FIGS. 8B to 8C.
[0119]
In this case, when the “OK” button is operated in the guide display shown in FIG. 9D, the display shifts to the guide display shown in FIG. You will be able to enter what happened. Here, four buttons of “great”, “good”, “choro”, and “tempura” are presented as candidates, and the user selects a desired button from these buttons and performs a click operation (decision operation). To be.
The guide display shown in FIG. 9 (b) → FIG. 9 (c) → FIG. 9 (d) → FIG. 9 (e) is repeated for the number of members (in this case, three times), Tea shots can be taken.
Then, according to the procedure according to the guide display of FIG. 9 (b) → FIG. 9 (c) → FIG. 9 (d) → FIG. 9 (e), shooting and evaluation of the tee shots of all members (three people) are performed. Assume that input is complete.
At this stage, the recording files obtained by shooting the tee shots of the three members are named video4, video5, and video6 and recorded on the disc. And on the program,
party [0]. teeshot = video4;
party [1]. teeshot = video5;
party [2]. teeshot = video6;
In this format, each shot file is associated with who the shot is.
Further, based on the input operation for the guide display of FIG.
party [0]. teeshot_quality = OK;
party [1]. teeshot_quality = GREAT;
party [2]. teeshot_quality = CHORO;
The shot evaluation is registered in the format. In this case, a click operation is performed on the “OK” button for Mr. A's shot, the “GREAT” button for Mr. B's shot, and “CHORO” for Mr. C's shot. The result of the click operation on the "" button is reflected.
[0120]
When the procedure related to the tee shot is completed as described above, for example, the guide display shown in FIG. In this guide display, the user is then prompted to arbitrarily shoot a desired scene (synonymous with recording a captured image here). In this case, as a candidate for the shooting content, a “landscape” button corresponding to the shooting of the landscape, a “comment” button corresponding to the shooting of the scene commented by the player, and any later than the tee shot And a “shot” button corresponding to the shooting of the next shot.
The user selects one of these buttons and performs a click operation according to the content he / she wants to shoot.
[0121]
If a click operation is performed on the “landscape” button under the guide display shown in FIG. 9F, for example, the guide display has a content for encouraging shooting of the landscape as shown in FIG. It becomes. Here, a telop “Please take a landscape” is displayed for the current captured image. The user may shoot a target landscape while watching the captured image while viewing the display unit 6A on which the guide display is displayed.
[0122]
If a click operation is performed on the “comment” button on the guide display shown in FIG. 9F, a guide display for shooting a scene where the player is commenting as shown in FIG. 10B. Display is performed. Also in this guide display, for example, a telop “Please take a comment” on the current captured image and a shooting designation frame for determining the composition are displayed in an impose manner. The user takes a picture of the commenting user while monitoring on the guide display.
Although not shown here, when shooting a “comment”, for example, a guide display similar to that shown in FIG. 9B is displayed to specify which player's comment is to be shot. An input operation is also performed.
[0123]
Alternatively, if a click operation on the “shot” button is performed on the guide display shown in FIG. 9F, the display shifts to the guide display shown in FIG. In this guide display, a hole number where a shot to be shot is to be taken, a display for prompting the user to input the number of shots in that hole, and a button display for inputting the type of shot (here, “tee”, “iron” “Problem” and “Pat” buttons are prepared, and although not shown here, for example, a guide display according to FIG. The input operation is prompted.
When the input operation for the guide display in FIG. 10C is completed, as shown in FIG. 10C, a telop that prompts the player to take a shot in about 5 seconds and a shooting designation frame are captured images. The implied guide display is displayed, and the user is allowed to take a shot.
Although omitted here for the sake of avoiding duplication of explanation, in this case as well, when the shooting of the player's shot is completed, for example, the review and re-shooting as shown in FIGS. For this purpose, a guide display for inputting a shot evaluation or a guide display for inputting a shot evaluation may be displayed.
The user repeats the procedure described with reference to FIGS. 9 (f) to 10 (d) as necessary during play.
[0124]
Here, an example of the contents of the program obtained by the procedure of FIG. 9 (f) to FIG. 10 (d) will be given. ,
First, as a case corresponding to the case where a shot was taken, for example, suppose that Mr. A's trouble shot at the second shot of the fourth hole was recorded as video7.
track [0]. track = video7;
track [0]. type = SHOT;
track [0]. hole = 4;
track [0]. Shotnumber = 2;
track [0]. Shottype = TROUBLE; // TROUBLE means trouble shot.
track [0]. personnumber = 0; // party [0] is Mr. A.
Such additional information is registered.
[0125]
And if B's comment on this shot was recorded as video8, for example,
track [1]. track = video8;
track [1]. type = COMMENT;
track [1]. personnumber = 0;
The additional information is registered as described above.
[0126]
Also, if you shoot the comment of Mr. B above and then shoot the scenery as video9,
track [2]. track = video9;
track [2]. type = SCENE;
track [2]. hole = 4; // Indicates how many holes were taken
The additional information is registered as described above. Note that this additional information includes information indicating the number of holes in which this landscape was shot. The information about the number of holes in this additional information indicates the shooting situation before this (for example, this It is possible to record by analogy from information such as a hole number input corresponding to a shot taken earlier.
[0127]
Then, for example, when a predetermined input operation (not shown here) corresponding to the end of play is performed, or when it is estimated that play has ended from the shooting situation so far, first, FIG. Guide display for score input shown in e) is performed. In response to this guide display, for example, the user operates the jog dial 311 to input a score value for each member. In addition, such a score input screen may be configured so that a score can be input as appropriate so that it can be called as necessary even during play.
As a program that supports score input,
party [0]. score_hole [1] = 3;
party [0]. score_hole [2] = 5;
Recording is performed as described above.
[0128]
Then, when the score input for all the members is completed, for example, a guide display shown in FIG. 10F is displayed. This guide display is for encouraging shooting of scenes in which each member is commenting after playing. In this case, the member to be shot as shown in the figure (as shown in FIG. 9B). First, a screen for selecting a member's face is displayed as a thumbnail image is displayed.
When the user performs an operation for selecting a member to be a subject on this screen, for example, as a guide display, a guide display that prompts shooting for several seconds as shown in FIG. Guide display for prompting confirmation after photographing as shown in FIG. 9D is performed, and the user confirms photographing, recording state, and re-taking according to this display. The same procedure is followed to shoot a scene where all members are commenting.
For example, if the comments of three members are taken in the order of Mr. A, Mr. B, Mr. C, and these are recorded as recorded files with file names video10, video11, and video12, respectively,
party [0]. endcomment = video10;
party [1]. endcomment = video11;
party [2]. endcomment = video12;
In this way, association with each recording file is performed.
[0129]
Upon completion of all the procedures so far, program information based on the input operation of necessary information for creating a video work and a recording file (image / audio information) serving as editing material are obtained as editing material information. It will be.
[0130]
When the guide display shown in FIGS. 8 to 10 is performed, the program AE (in the lens block of the video camera device is actually based on the exposure control value stored in the editing application program. It is assumed that the correction for the Automatic Exposure) function is being performed.
That is, according to the script set as the editing application program, it is possible to easily assume under what circumstances the shooting for collecting the editing material under the guide display is performed. For example, if it is a golf competition, it will be photographed outdoors as a situation.
Therefore, a correction value for AE suitable for the predicted shooting situation is prepared in the editing application program in advance, and AE correction is automatically performed with this correction value when shooting according to the actual guide display. For example, when dealing with a golf competition, an AE correction value that is optimal for outdoor shooting is prepared in an editing application program, and the program AE is controlled by this correction. As a result, for example, even if the user does not perform an operation such as changing the AE program, the AE program is controlled so as to maintain an almost optimal state. It is possible to obtain.
[0131]
8-3. Edit playback (playback as a video work)
Then, in the video camera device of the present embodiment, according to the script set up under the application program for editing, the video using the recording file as the material using the input information obtained as described above Perform editing to create a work. This editing process is realized by a process of configuring a script for designating a reproduction timing including the reproduction order of each recorded file, a superimpose for the reproduced recorded file, and the like. Then, by interpreting the script obtained in this manner and executing image processing for reproducing the recorded file and applying special effects, reproduction as a video work is performed. The created script is saved by being recorded on an auxiliary data track on the disk in which the editing application program corresponding to the script is stored.
[0132]
Therefore, first, an example of a reproduction mode of a video work created by a script described according to the procedure described with reference to FIGS. 8 to 10 will be described with reference to FIGS. In addition, description contents corresponding to a reproduction example of a video work described below and a script generation method will be described later.
[0133]
For example, a user plays a video of a golf editing disc used for shooting at a golf course (at this stage, a recording file serving as an editing material and a script for editing a video work are already recorded). The camera is loaded into a camera and a playback operation is performed.
In response to this operation, the video camera reads the script from the disk, interprets the script, plays the recorded file, and performs image / audio signal processing. Realize.
[0134]
In this case, first, the opening title as shown in FIG. 11A is displayed together with the output of the sound effect.
Subsequently, the member introduction image is displayed as shown in FIG. Here, the member's face photo is displayed along with its name. What is necessary is just to use what was used by the guide display of FIG.9 (b) for this member's face photograph. That is, the thumbnail image used for the guide display in FIG. 9B is recorded on the thumbnail track of the disc at the time of the input operation and shooting at the site.
[0135]
Subsequently, for example, as shown in FIG. 11C, the scene where Mr. A talks about his aspiration is displayed as a moving image (recorded file recorded as video1). At this time, since the video 1 recording file is being reproduced, the voice in which Mr. A talks about his aspiration is synchronously output by the voice. Further, here, the character display (superimpose display Sim) is performed like “Mr. A who talks about today's enthusiasm”. The display of the scene in which this member talks about ambition is performed for Mr. B and Mr. C in the same manner following Mr. A (reproduction of video 2 and video 3).
[0136]
After this, the scene of each member's tee shot is displayed. For example, here, after the comment scene of the aspiration of each member shown in FIG. 11 (c) is displayed, the scene where A is taking a tee shot is displayed as shown in FIG. 11 (d). The state is shown (video 4). Here, a superimpose display Sim indicating the information of the hole and a superimpose display Sim explaining the scene “Mr. A's tee shot!” Are performed like “1H 300 yd par5”. Furthermore, a superimpose display “Simp” is displayed using characters “GREAT” to effectively explain the great shot. For example, the “GREAT” superimpose display “Simp” is displayed in accordance with the input operation in accordance with the guide display shown in FIG. 9 (e). As an effect, the superimpose display “Simp” of such a design is automatically displayed. Such tee shot scenes are also displayed in order for all members (videos 5 and 6). At this time, as long as the basic display is obtained by playing the recorded file, the recorded audio may be played back at the same time, which can be easily realized. It is.
[0137]
Thereafter, for example, an image and sound of a recording file arbitrarily shot on site after the tee shot is output with some required editing effect.
In this case, after displaying the tee shot scene of each member shown in FIG. 11 (d), as shown in FIG. 12 (a), the scene of Mr. A's trouble shot (recorded as video7) Is displayed.
Here, the contents indicating hole information and the contents indicating that Mr. A is in a trouble shot together with the current score are inserted as the superimpose display Sim.
[0138]
Subsequently, for example, as shown in FIG. 12B, by playing video 8, the video of Mr. A who makes a comment after the trouble shot is displayed, and the voice of the comment at this time is also output. In addition, here, as the superimpose display Sim, for example, a description of the current situation such as “Mr. A who comments” and a progress process and score of the play such as “4H end current score + 8” are shown. Things are displayed.
[0139]
Also, in this case, following FIG. 12B, a moving image (or still image) in which a green of a certain hole is captured as a landscape captured by the user as video 9 is illustrated in FIG. Is displayed. In this case, the BGM prepared by the editing application program is appropriately selected and output as sound. At this time, only the BGM may be used as the audio output, or the BGM may be synthesized and output with respect to the audio obtained by reproduction from the video 9 recording file.
[0140]
If such display is performed and video output until the end of the game is performed, the display screen is, for example, as shown in FIG. A score indicating the performance of each member so far is displayed. This score display is obtained based on information obtained by the score input operation shown in FIG.
[0141]
When the score display is completed, a display in the form as shown in FIG. 13B is performed as an ending title. Here, for example, an image of a smiling character prepared by an editing application program is displayed, and the winners “That ’s why this time” and “Mr. B won!” A superimpose display Sim shown is displayed. The winner is identified by referring to the score of each member obtained by the score input operation shown in FIG. 10E, as will be described later in the script creation method.
With the end of the display of the ending title, the playback as a video work ends.
[0142]
8-4. Script contents
Next, the contents of a script for realizing the display as the video work shown in FIGS.
As described above, in the video camera of this embodiment, the input information obtained according to the guide display as shown in FIGS. 8 to 10 and the file as the editing material recorded as the recording file are used in combination. In this way, meta information called a script file is configured. This script file is constructed under the condition that an application program for editing is being executed at a required opportunity (in practice, preferably immediately after) after the information input and shooting according to the guide display are completed. It is assumed that the video controller 38 executes using a subset of XML mounted therein.
Here, based on the SMIL grammar, an example is shown in which JAVA A431plapple is used for the superimpose.

[0143]
The image processing for superimposing the text designated by the superimpose applet in the script may be executed as follows, for example.
[0144]
One is to use the function of the character generator and on-screen display realized by the video controller 38 and the data processing / system control circuit 31. That is, the video controller 38 generates character / symbol information of the designated text when the interpreted script is to display the text designated by the superimpose applet. Then, the control for the data processing / system control circuit 31 is executed so that the generated characters / symbols and the like are displayed at a predetermined position on the image of the recording file being reproduced.
[0145]
In addition, with respect to the characters of the superimpose display Sim designed as “柏 CC golf competition” in FIG. 11A and “GREAT” in FIG. Although it is possible to generate data, for example, in the case of a special design as described above, this image is recorded in advance as a file in a required directory as data of an editing application program. If processing is performed so that data is read out as necessary and superimposed on a playback image of a recorded file (video) (such image processing is performed by the data processing / system control circuit 31), the video controller 38 In addition, the processing load on the data processing / system control circuit 31 is reduced.
[0146]
Note that, for example, the superimpose processing is applied mutatis mutandis to the case of realizing the display of a telop in the guide display with the captured image as the background and the display of the photographing designation frame shown in FIGS.
That is, the video controller 38 executes control processing for reading out the telop prepared by the editing application program and the image data file of the shooting designation frame from the disk and supplying them to the video signal processing unit 3. The video signal processing unit 3 performs a decoding process on the supplied image data file, for example.
In the data processing / system control circuit 31, the decoded telop and image data of the designated shooting frame are displayed at a required position on the captured image supplied from the camera block under the control of the video controller 38. The image composition processing is performed. The image data is displayed on the display unit 6A.
[0147]
8-5. Script generation method
Next, a description will be given of a script generation method obtained under an environment in which the editing application program of this embodiment is activated.
Here, as a specific example, the case of generating the script contents for realizing the display as the video work shown in FIGS. 11 to 13 is taken as an example, and the input variables and other sets are set for each script section. Let's look at how wizards are generated from the information of the above. Here, the parameter calculation method is shown in C ++ language.
Section 1 (Figure 11 (a))
course = coursesen; // Follow the course selected by the user
date = getdate (); // Date is received from a calendar function provided in the set (for example, the video controller 38).

Section 8 (Figure 13 (a))
The score input in advance is score. It is converted into a file called txt and recorded on the disc.
Section 9 (Figure 13 (b))
First, the member with the lowest total score is searched. If it is the i th person
video = party [i]. endcomment;
topcaption = ”, so this time,“;
bottomcaption "value = party [i] .name +" wins ";
The script can be derived from the input information obtained by the input operation described with reference to FIGS. 8 to 10 and the recorded file of the captured image by executing such calculation.
[0148]
8-6. Processing action
Next, a processing operation example for realizing the editing operation described so far will be described with reference to the flowcharts of FIGS. 13 and 14. The processing operation shown in FIG. 13 and FIG. 14 is performed by the data controller / system control circuit 31, the driver controller 46, and the camera controller 25 as necessary. Alternatively, it is realized by executing signal processing. Further, this processing is a processing operation executed under the environment where the editing application program is activated.
[0149]
The processing operation shown in FIG. 14 shows processing until a script is generated based on, for example, the guide display shown in FIGS. 8 to 10 and information input (including recording of a captured image) performed according to the guide display. Has been.
First, when an instruction for operating the guide function display of the editing application program is given by a predetermined operation on the operation unit 7 by the user, the video controller 38 proceeds to step S101 and edits from the loaded disc. A control process for reading out the application program is executed.
Then, in the subsequent step S102, for example, processing for starting an editing application program is executed using the RAM in the video controller 38, for example.
[0150]
In the next step S103, the exposure control value for the imaging optical system of the video camera device included in the editing application program is referred to, and based on this exposure control value, the AE (Automatic Exposure) in the lens block 1 is performed. Control for performing exposure correction on the function is executed. In this process, for example, the video controller 38 instructs the camera controller 25 to execute control for AE correction. The camera controller 25 executes control on the lens block 1 so that the AE is appropriately corrected based on the exposure control value.
[0151]
Then, in the next step S104, control processing for performing guide display is started in accordance with the started editing application program. Thereby, after that, for example, guide display is performed on the display unit 6A.
[0152]
Step S105 stores the input operation sequentially performed according to the instruction prompted by the guide display and the content (input information, here, the operation input information and the recording file) obtained by photographing (recording). The process for performing is performed.
That is, for example, as described with reference to FIGS. 8 to 10, the user performs a required input operation or recording in accordance with the input of information prompted for each guide display, which is obtained by these input operations. A process for holding information and a recording file obtained by recording as an editing material is executed. Here, it is assumed that input information (operation input information) obtained by operation input is held in, for example, a RAM inside the video controller 38. In addition, a recording file obtained by shooting is recorded as a file (track) in a directory in a disk folder.
Then, for example, if all information input according to the guide display is performed (that is, the guide display ends), the process proceeds to step S106.
[0153]
In step S106, processing for reconfiguring the held content according to a script preset as an editing application program is executed. That is, the program contents described in parallel with the description with reference to FIGS. 8 to 10 are set. Here, the process of step S105 is assumed to be executed after the end of the guide display. However, in practice, for example, as the process of step S105, content acquisition (holding of operation input information and recording of a recording file) is performed. The process of step S106 may be executed every time the process is performed.
[0154]
When the processing of step S106 is completed, the video controller 38 proceeds to step S107, uses the content of the content reconstructed as described above, and executes a script according to the script preset by the editing application program. Execute the process to generate. As a result, for example, a script having the description contents as described above is obtained.
[0155]
In the next step S108, control processing for recording the script generated as described above as a script file on the auxiliary data track of the disc is executed, and the processing so far is terminated. .
Through the processing so far, in addition to the editing application program recorded in advance, a recording file serving as editing material and a script file in which a description for designating editing contents is recorded are recorded.
[0156]
Next, editing and playback using the disc obtained as described above, that is, processing operation for playing back a video work based on a recording file serving as editing material will be described with reference to the flowchart of FIG.
[0157]
For example, if a required operation for starting reproduction of a video work is performed on the operation unit, the video controller 38 proceeds to the process shown in FIG.
In the process shown in this figure, a script recorded on the disk is first read in step S201. Here, the script to be read is a script that is created in accordance with the execution of the editing application program in advance and describes the contents for reproducing the video work.
The script read from the disk is stored in a predetermined area of the buffer memory 32, for example. In addition, if the storage capacity of the RAM inside the video controller 38 is sufficient, it may be configured to store in the internal RAM.
[0158]
Then, in step S202, interpretation of the script file read from the disk as described above is started, and playback processing according to the description content of the interpreted script is executed as processing in step S203. In other words, a necessary recording file (and a file such as a BGM audio track) required in accordance with the script description is read from the disk, and a reproduction process for outputting this as an image / audio is executed. Control for a required functional circuit unit is executed. At the same time, for example, image signal processing for superimpose display of required characters and symbols corresponding to the <applet> tag, audio signal processing for BGM output, etc. Execute.
By the processing in step S203, for example, the image / sound reproduction output mode as the video work shown in FIGS. 11 to 13 is obtained.
[0159]
Then, if it is determined that the interpretation of the script has been completed as the processing in step S204, the processing so far is terminated. In other words, the playback operation so far is finished in a state where the video work has been played to the end. Although not shown in this figure, for example, if a stop operation is performed, the playback of the video work is terminated at that time, and if a pause operation is performed, the pause operation is performed. Control processing is executed so that the displayed image is maintained and the progress of script interpretation is also temporarily stopped.
[0160]
In the above embodiment, the configuration for realizing the editing process for creating the video work corresponding to the golf competition has been described. However, this is merely an example, and the video work according to other purposes is created. In this case, it can be realized according to the configuration described so far.
[0161]
Moreover, the guide display shown as the said embodiment, how to give various edit effects in the state finished as a video work, etc. can be changed suitably according to actuality.
Further, the script language employed in the present embodiment is not limited to SMIL, and a configuration employed by another language may be employed.
[0162]
Further, for example, the editing operation examples shown in FIGS. 8 to 10 as the above-described embodiment are merely examples, and other operation modes and the like can be used as long as the operation modes can be simplified by general users. Other display forms may be adopted. As an example, the display unit 6A is configured to have a function as a touch panel, and an operation similar to the description of FIGS. 8 to 10 is pointed to the display unit 6A using a finger or some pointing device. It is also possible to do so.
[0163]
Further, the video camera of the present embodiment is a disc recording / reproducing apparatus based on MD-DATA2 as a video recording / reproducing part. However, the video recording / reproducing part is not limited to the configuration of the present embodiment, and other parts. It may be a recording / reproducing apparatus corresponding to the type of disc-shaped recording medium.
Further, in the present embodiment, the MPEG2 system has been described for compressing moving image data. However, for example, a method capable of compressing and encoding other moving image data may be employed. Further, the compression method for still image data and audio data is not particularly limited to those exemplified as the present embodiment (JPEG, ATRAC2, etc.).
[0164]
【The invention's effect】
As described above, the present invention realizes a GUI as a guide function for prompting input of information necessary for editing as an editing process program (editing application program) (input instruction program) ), And according to this guide display, input the required input information by input operation and record the captured image (including audio) on the recording medium, then edit according to the above program (editing program) As a process, based on the input information obtained by the input operation, a script for giving a required reproduction output mode for the captured image file is generated and recorded on the recording medium. At the time of reproduction, the captured image file is reproduced while providing an editing effect according to the description content of the script.
That is, the user performs an input operation or shooting according to the guide display at the time of shooting without performing particularly complicated editing processing on the source of images, sounds, and the like obtained by shooting with a video camera or the like.
