Description

表示装置および表示方法Display device and display method
　本発明は、複数のサムネイル画像を表示可能な表示装置および表示方法に関する。 The present invention relates to a display device and a display method capable of displaying a plurality of thumbnail images.
　近年、ＨＤＤ（Hard Disk Drive）の大容量化に伴い、デジタルスチルカメラ（ＤＳＣ：Digital Still Camera）またはデジタルビデオカメラ（ＤＶＣ：Digital Video Camera）によって撮像された画像や、インターネット等の通信網を通じて取得した画像を１つのＨＤＤやリムーバブルディスクに多数記録できるようになった。 Acquired through digital still camera (DSC: Digital に よ っ て Camera) or digital video camera (DVC: Digital Camera) and communication networks such as the Internet with the recent increase in HDD (Hard Drive) capacity A large number of recorded images can be recorded on one HDD or removable disk.
　このように記録された多数の画像は、その中から１の画像を特定する際、そのサイズが縮小されたサムネイル画像が用いられ、例えば、元となる画像の記録順にモニタ上に並べられる。ユーザは、かかる複数のサムネイル画像を一度に参照することで、所望する任意の画像に対応するサムネイル画像を容易に選択することができ、その後、ユーザが選択したサムネイル画像の元となる画像が再生される。 The large number of images recorded in this way are thumbnail images with reduced sizes when specifying one image from among them, and are arranged on the monitor in the order of recording of the original images, for example. The user can easily select a thumbnail image corresponding to an arbitrary desired image by referring to the plurality of thumbnail images at a time, and then the original image of the thumbnail image selected by the user is reproduced. Is done.
　このとき、ユーザは、十字キーやポインティングデバイスを通じて、所望するサムネイル画像にフォーカスを移動することで、複数のサムネイル画像から１のサムネイル画像を選択する。サムネイル画像は、そのフォーカスの移動に従って、画像単位で１枚ずつ出現または消失することとなる。対象となる画像数が少ない場合、このような画像単位の表示は問題ないが、画像数が多くなると、その操作が煩雑になる。そこで、所定の操作を経由することで、表示されたページ単位（所定数のサムネイル画像単位）でサムネイル画像を切り換える技術が開示されている（例えば、特許文献１）。
特開２００３－１４３５１２号公報 At this time, the user selects one thumbnail image from the plurality of thumbnail images by moving the focus to the desired thumbnail image through the cross key or the pointing device. The thumbnail images appear or disappear one by one in accordance with the movement of the focus. When the number of images to be processed is small, such display in image units is not a problem, but when the number of images is large, the operation becomes complicated. Therefore, a technique for switching thumbnail images in units of displayed pages (a predetermined number of thumbnail images) through a predetermined operation is disclosed (for example, Patent Document 1).
JP 2003-143512 A
　上述した技術では、モニタ上のフォーカスを進ませたり戻したりすることでページを切り換えることができる。ページの切換が生じると、表示装置は、新たなページに表示すべきサムネイル画面を元画像から新たに生成し、生成されたサムネイル画像から順にモニタに表示していく。従って、新しいページでは、生成されたサムネイル画面がモニタの左上から順に描画されることとなり、すべてのサムネイル画像が表示されるまで多少の時間を要する。従って、サムネイル画像の並びを例えば画像の記録順とした場合、記録した日時の古いサムネイル画像が先に表示され、日時の新しいサムネイル画像は後から表示されることとなる。 In the above-described technology, pages can be switched by moving the focus on the monitor back and forth. When the page is switched, the display device newly generates a thumbnail screen to be displayed on a new page from the original image, and sequentially displays the generated thumbnail image on the monitor. Therefore, in the new page, the generated thumbnail screen is drawn in order from the upper left of the monitor, and it takes some time until all thumbnail images are displayed. Therefore, when the arrangement of the thumbnail images is, for example, the image recording order, the old thumbnail images with the recorded date and time are displayed first, and the new thumbnail images with the new date and time are displayed later.
　このような状況下で、サムネイル画像へのフォーカスを記録時刻の新しい方に移動した場合、そのページ切換において、次ページの一番古いサムネイル画像が最初に表示される。かかるサムネイル画像は前ページにおける一番新しいサムネイル画像の次の画像に当たるので理にかなっていると言える。しかし、サムネイル画像へのフォーカスを記録時刻の古い方に移動した場合、そのページ切換において、ユーザが最初に視認したいのは前ページの一番新しいサムネイル画像、即ち、モニタ右下に配置されるべきサムネイル画像である。しかし、従来の表示装置は、フォーカスの移動方向に拘わらず、一番古いサムネイル画像、即ち、モニタ左上に配置されるサムネイル画像から表示していた。従って、ユーザは、その目的とするサムネイル画像が表示されるまで待たなくてはならず、不満を感じる場合があった。 In such a situation, when the focus on the thumbnail image is moved to a newer recording time, the oldest thumbnail image on the next page is displayed first when switching the page. It can be said that such a thumbnail image makes sense because it is the next image after the newest thumbnail image on the previous page. However, if the focus on the thumbnail image is moved to the oldest recording time, the page that the user wants to see first should be the newest thumbnail image of the previous page, that is, the lower right corner of the monitor. It is a thumbnail image. However, the conventional display device displays the oldest thumbnail image, that is, the thumbnail image arranged on the upper left of the monitor, regardless of the focus moving direction. Therefore, the user has to wait until the target thumbnail image is displayed, and may feel dissatisfied.
　本発明は、このような課題に鑑み、ユーザのサムネイル画像へのフォーカスの移動方向に応じて、ユーザの所望するサムネイル画像を適切な表示順で表示し、サムネイルの検索処理の効率化とユーザの満足度の向上を図ることが可能な表示装置および表示方法を提供することを目的としている。 In view of such a problem, the present invention displays the thumbnail images desired by the user in an appropriate display order according to the moving direction of the focus to the thumbnail image of the user, and improves the efficiency of the thumbnail search process and the user's It is an object of the present invention to provide a display device and a display method capable of improving satisfaction.

　中央制御部１６０は、中央処理装置（ＣＰＵ）や信号処理装置（ＤＳＰ：Digital Signal Processor）を含む半導体集積回路により表示装置１００全体を管理および制御する。メモリ１６２は、ＲＯＭ、ＲＡＭ、ＥＥＰＲＯＭ、不揮発性ＲＡＭ、フラッシュメモリ、ＨＤＤ等で構成され、中央制御部１６０で処理されるプログラムや画像等を保持する。 The central control unit 160 manages and controls the entire display device 100 by a semiconductor integrated circuit including a central processing unit (CPU) and a signal processing unit (DSP: Digital Signal Processor). The memory 162 includes a ROM, a RAM, an EEPROM, a nonvolatile RAM, a flash memory, an HDD, and the like, and holds programs, images, and the like that are processed by the central control unit 160.
　また、中央制御部１６０は、撮像制御部１８０、サムネイル生成部１８２、サムネイル表示制御部１８４、画像選択制御部１８６、画像再生制御部１８８、サムネイル切換制御部１９０としても機能する。 The central control unit 160 also functions as an imaging control unit 180, a thumbnail generation unit 182, a thumbnail display control unit 184, an image selection control unit 186, an image reproduction control unit 188, and a thumbnail switching control unit 190.
　撮像制御部１８０は、被写体に対して、焦点調整や露光調整を含む撮像制御を遂行する。具体的に、撮像制御部１８０は、撮像制御を遂行するための制御指令を撮像部１５０の駆動回路１７６に伝達し、駆動回路１７６は、撮像制御部１８０からの制御指令に従って、フォーカスレンズ１７０や絞り１７２を調整する。 The imaging control unit 180 performs imaging control including focus adjustment and exposure adjustment on the subject. Specifically, the imaging control unit 180 transmits a control command for performing imaging control to the drive circuit 176 of the imaging unit 150, and the drive circuit 176 performs the focus lens 170 and the control command according to the control command from the imaging control unit 180. The diaphragm 172 is adjusted.
　図３は、サムネイル生成部１８２が生成したサムネイル画像２０２をサムネイル表示制御部１８４がビューファインダ１０８に表示させる手順を説明するための説明図である。ここでは、撮像部１５０による記録時刻（撮像時刻）の古い方から順に、元画像Ｄ０１からＤ２２までを記録している記録媒体１１０を有する表示装置１００を例に挙げて説明する。ここで、元画像およびサムネイル画像２０２は、動画像または静止画像とすることができる。 FIG. 3 is an explanatory diagram for explaining a procedure for causing the thumbnail display control unit 184 to display the thumbnail image 202 generated by the thumbnail generation unit 182 on the viewfinder 108. Here, the display device 100 including the recording medium 110 that records the original images D01 to D22 in order from the oldest recording time (imaging time) by the imaging unit 150 will be described as an example. Here, the original image and the thumbnail image 202 can be a moving image or a still image.
　まず、サムネイル生成部１８２は、ユーザによる所定の操作キー１０６への入力に応じて、サムネイル画像２０２を並べるためのサムネイルページ２００ａの画像を生成しメモリ１６２に記録する。そして、図３（ａ）に示すように、サムネイル表示制御部１８４は、メモリ１６２に記録されたサムネイルページ２００ａの画像を信号処理部１５２に出力し、サムネイルページ２００ａをビューファインダ１０８に表示させる。 First, the thumbnail generation unit 182 generates an image of the thumbnail page 200a for arranging the thumbnail images 202 in accordance with an input to the predetermined operation key 106 by the user, and records it in the memory 162. 3A, the thumbnail display control unit 184 outputs the thumbnail page 200a image recorded in the memory 162 to the signal processing unit 152, and causes the viewfinder 108 to display the thumbnail page 200a.
　そして、サムネイル生成部１８２は、画像記録読取部１５６に、所定の条件に従って１の元画像（例えば、元画像Ｄ０１）を記録媒体１１０から読み出させ、画像伸長部１５８を通じてその元画像を復号させ、静止画像で表されるサムネイル画像２０２（例えば、サムネイル画像Ｔ０１）を生成する。そして、図３（ｂ）に示すように、サムネイル表示制御部１８４は、サムネイル生成部１８２によって生成されたサムネイル画像２０２（図３（ｂ）中、Ｔ０１で示す）をメモリ１６２上のサムネイルページ２００ａの画像の所定の位置（例えば、左上）に重畳し、重畳後のサムネイルページ２００ｂの画像を信号処理部１５２に出力し、そのサムネイルページ２００ｂをビューファインダ１０８に表示させる。 Then, the thumbnail generation unit 182 causes the image recording / reading unit 156 to read one original image (for example, the original image D01) from the recording medium 110 according to a predetermined condition, and to decode the original image through the image expansion unit 158. Then, a thumbnail image 202 (for example, a thumbnail image T01) represented by a still image is generated. Then, as shown in FIG. 3B, the thumbnail display control unit 184 displays the thumbnail image 202 generated by the thumbnail generation unit 182 (indicated by T01 in FIG. 3B) on the thumbnail page 200a on the memory 162. Is superimposed on a predetermined position (for example, upper left) of the image of the image, and the image of the thumbnail page 200b after the superimposition is output to the signal processing unit 152, and the thumbnail page 200b is displayed on the viewfinder 108.
　次にサムネイル生成部１８２は、画像記録読取部１５６に、所定の条件の２番目に相当する１の元画像（例えば元画像Ｄ０２）を記録媒体１１０から読み出させ、画像伸長部１５８を通じてその元画像を復号させ、新たなサムネイル画像２０２（例えば、サムネイル画像Ｔ０２）を生成する。そして、図３（ｃ）に示すように、サムネイル表示制御部１８４は、新たに生成されたサムネイル画像２０２（図３（ｃ）中、Ｔ０２で示す）をメモリ１６２上のサムネイルページ２００ｂの画像の所定の位置（例えば、左上より少し右）に重畳し、重畳後のサムネイルページ２００ｃの画像を信号処理部１５２に出力し、そのサムネイルページ２００ｃをビューファインダ１０８に表示させる。 Next, the thumbnail generation unit 182 causes the image recording / reading unit 156 to read one original image corresponding to the second predetermined condition (for example, the original image D02) from the recording medium 110, and through the image expansion unit 158, the original image is read. The image is decoded to generate a new thumbnail image 202 (for example, thumbnail image T02). Then, as shown in FIG. 3C, the thumbnail display control unit 184 displays the newly generated thumbnail image 202 (indicated by T02 in FIG. 3C) of the image of the thumbnail page 200b on the memory 162. The image is superimposed on a predetermined position (for example, slightly to the right from the upper left), the image of the thumbnail page 200c after being superimposed is output to the signal processing unit 152, and the thumbnail page 200c is displayed on the viewfinder 108.
　以下、サムネイル表示制御部１８４が、「サムネイル生成部１８２によって生成されたサムネイル画像をメモリ１６２上のサムネイルページ２００の画像の所定の位置に重畳し、重畳後のサムネイルページ２００の画像を信号処理部１５２に出力し、そのサムネイルページ２００をビューファインダ１０８に表示させる」動作を、単に、「サムネイル表示制御部１８４がサムネイル画像２０２を表示させる」と省略する。 Hereinafter, the thumbnail display control unit 184 “superimposes the thumbnail image generated by the thumbnail generation unit 182 on a predetermined position of the image on the thumbnail page 200 on the memory 162, and displays the image on the thumbnail page 200 after the superimposition on the signal processing unit. The operation of “output to 152 and display the thumbnail page 200 on the viewfinder 108” is simply omitted as “the thumbnail display control unit 184 displays the thumbnail image 202”.
　こうして、図３（ｄ）に示すように、サムネイル表示制御部１８４は、サムネイル生成部１８２がサムネイル画像２０２を生成した順（ここでは、サムネイル画像Ｔ０１からＴ１２）に、即ち、図３（ｄ）中破線矢印で示す順に、サムネイル画像２０２を左上から右側に向かって４枚表示させる。そして、サムネイル表示制御部１８４は、１列目の表示が終了すると、次の列の左から右に向かって４枚表示させ、最終列まで繰り返す。従って、サムネイル表示制御部１８４は、サムネイル生成部１８２が生成したサムネイル画像２０２を、その生成順に従った表示順でビューファインダ１０８に表示させるので、１ページ分のサムネイル画像２０２の表示が完了するまでには、多少の時間を要する。 In this way, as shown in FIG. 3D, the thumbnail display control unit 184 operates in the order in which the thumbnail generation unit 182 generates the thumbnail images 202 (here, the thumbnail images T01 to T12), that is, FIG. Four thumbnail images 202 are displayed from the upper left to the right in the order indicated by the middle dashed arrows. When the display of the first column ends, the thumbnail display control unit 184 displays four images from the left to the right of the next column, and repeats until the last column. Accordingly, the thumbnail display control unit 184 causes the viewfinder 108 to display the thumbnail images 202 generated by the thumbnail generation unit 182 in the display order according to the generation order, so that the display of the thumbnail images 202 for one page is completed. Takes some time.
　こうして、サムネイル表示制御部１８４は、サムネイル生成部１８２がサムネイル画像２０２を生成した順に、所定数（例えば、４枚×３列の１２）のサムネイル画像２０２をビューファインダ１０８に表示させることとなる。ここでは、記録媒体１１０中の複数の元画像が１２のサムネイル画像２０２毎にページ単位で取り扱われ、ビューファインダ１０８には所定の条件による並び順を維持するように並列表示される。 Thus, the thumbnail display control unit 184 causes the viewfinder 108 to display a predetermined number of thumbnail images 202 (for example, 4 sheets × 12 columns 12) in the order in which the thumbnail generation unit 182 generated the thumbnail images 202. Here, a plurality of original images in the recording medium 110 are handled in units of pages for each of the 12 thumbnail images 202, and are displayed in parallel on the viewfinder 108 so as to maintain the arrangement order according to a predetermined condition.
　本実施形態において、サムネイル生成部１８２は、記録時刻の古い順または新しい順にサムネイル画像２０２を生成しているが、これに限定されず、ファイルサイズの昇順または降順や、ファイル名順（例えば、アルファベット順）等の所定の条件に従って、サムネイル画像２０２を生成してもよい。 In the present embodiment, the thumbnail generation unit 182 generates the thumbnail images 202 in order of oldest recording time or newest recording time. However, the present invention is not limited to this. The thumbnail image 202 may be generated according to a predetermined condition such as (in order).
　図４は、サムネイルページ２００から任意の動画像を再生する手順を説明するための説明図である。図４（ａ）に示すように、画像選択制御部１８６は、ユーザによる所定の操作キー１０６への選択入力を介して、ユーザに任意のサムネイル画像２０２を、例えば、図中縁取りで示したフォーカスを移動することで選択させ、選択されたサムネイル画像２０２（選択結果）を受け付ける。続いて、図４（ｂ）に示すように、画像再生制御部１８８は、ユーザによる所定の操作キー１０６への選択決定入力を介して、画像記録読取部１５６に選択決定されたサムネイル画像２０２にかかる元画像（例えば、元画像Ｄ０３）を記録媒体１１０から抽出し、信号処理部１５２を通じてビューファインダ１０８に元画像を出力させる。 FIG. 4 is an explanatory diagram for explaining a procedure for reproducing an arbitrary moving image from the thumbnail page 200. As shown in FIG. 4A, the image selection control unit 186 provides the user with an arbitrary thumbnail image 202, for example, a focus indicated by a border in the drawing, through selection input to a predetermined operation key 106 by the user. The selected thumbnail image 202 (selection result) is received. Subsequently, as shown in FIG. 4B, the image reproduction control unit 188 displays the thumbnail image 202 selected and determined by the image recording / reading unit 156 via the selection determination input to the predetermined operation key 106 by the user. The original image (for example, the original image D03) is extracted from the recording medium 110, and the viewfinder 108 outputs the original image through the signal processing unit 152.
　サムネイル切換制御部１９０は、ユーザによる任意の操作キー１０６への選択入力に応じて、複数のサムネイルページ２００をサムネイル画像２０２の並び順（本実施形態では記録時刻順）に従って切り換える。そして、サムネイル表示制御部１８４は、サムネイル切換制御部１９０がサムネイルページ２００を順方向に切り換えた場合、新たなサムネイルページ２００のサムネイル画像２０２を並び順と同じ表示順でビューファインダ１０８に表示させる。 The thumbnail switching control unit 190 switches the plurality of thumbnail pages 200 in accordance with the arrangement order of the thumbnail images 202 (in the present embodiment, the recording time order) in response to a selection input to the arbitrary operation key 106 by the user. Then, when the thumbnail switching control unit 190 switches the thumbnail page 200 in the forward direction, the thumbnail display control unit 184 causes the viewfinder 108 to display the thumbnail images 202 of the new thumbnail page 200 in the same display order.
　図５は、サムネイル切換制御部１９０がサムネイルページ２００を順方向に切り換えた場合のサムネイル表示制御部１８４の動作を説明するための説明図である。ユーザによる所定の操作キー１０６への選択入力に応じて、サムネイル画像２０２へのフォーカスが移動され、フォーカスが１ページ目のサムネイルページ２００からさらに順方向（進む方向）に切り換えられると、サムネイル切換制御部１９０は、サムネイルページ２００を１ページから２ページに切り換える。そうすると、図５（ａ）から図５（ｂ）に示すように、サムネイル表示制御部１８４は、２ページ目のサムネイルページ２００のサムネイル画像２０２を並び順と同じ表示順（図５（ｂ）中破線矢印で示す）でビューファインダ１０８に表示させる。 FIG. 5 is an explanatory diagram for explaining the operation of the thumbnail display control unit 184 when the thumbnail switching control unit 190 switches the thumbnail page 200 in the forward direction. When the focus is moved to the thumbnail image 202 in response to a selection input to the predetermined operation key 106 by the user and the focus is further switched from the first thumbnail page 200 to the forward direction (forward direction), thumbnail switching control is performed. The unit 190 switches the thumbnail page 200 from the first page to the second page. Then, as shown in FIGS. 5A to 5B, the thumbnail display control unit 184 displays the thumbnail images 202 of the second thumbnail page 200 in the same display order (in FIG. 5B). It is displayed on the viewfinder 108 by a broken line arrow).
　従って、サムネイル切換制御部１９０がページを順方向に切り換えた場合、サムネイル表示制御部１８４は、新たなサムネイルページ２００に表示されるサムネイル画像２０２の中で、並び順が最も早いサムネイル画像２０２ａを、最初にビューファインダ１０８に表示させることになる。即ち、ユーザがサムネイル画像２０２へのフォーカスを記録時刻の新しい方に移動した場合、そのページ切換において、次ページの一番古いサムネイル画像２０２ａが最初に表示される。かかるサムネイル画像２０２ａは前ページにおける一番新しいサムネイル画像２０２ｂの次の画像に当たるので理にかなっていると言える。 Therefore, when the thumbnail switching control unit 190 switches the page in the forward direction, the thumbnail display control unit 184 selects the thumbnail image 202a with the earliest arrangement order among the thumbnail images 202 displayed on the new thumbnail page 200. First, it is displayed on the viewfinder 108. That is, when the user moves the focus on the thumbnail image 202 to the newest recording time, the oldest thumbnail image 202a of the next page is displayed first in the page switching. It can be said that such a thumbnail image 202a makes sense because it hits the image next to the newest thumbnail image 202b on the previous page.
　本実施形態において、サムネイル表示制御部１８４は、サムネイル切換制御部１９０がページを逆方向に切り換えた場合、新たなサムネイルページ２００のサムネイル画像２０２を並び順とは逆の表示順でビューファインダ１０８に表示させる。 In the present embodiment, when the thumbnail switching control unit 190 switches the page in the reverse direction, the thumbnail display control unit 184 displays the thumbnail images 202 of the new thumbnail page 200 on the viewfinder 108 in the display order opposite to the arrangement order. Display.
　図６は、サムネイル切換制御部１９０がページを逆方向に切り換えた場合のサムネイル表示制御部１８４の動作を説明するための説明図である。ユーザによる所定の操作キー１０６への選択入力に応じて、サムネイル画像２０２へのフォーカスが移動され、フォーカスが２ページ目のサムネイルページ２００から逆方向（戻る方向）に切り換えられると、サムネイル切換制御部１９０は、サムネイルページ２００を２ページから１ページに切り換える。そうすると、図６（ａ）から図６（ｂ）に示すように、サムネイル表示制御部１８４は、１ページ目のサムネイルページ２００のサムネイル画像２０２を並び順とは逆の表示順（図６（ｂ）中破線矢印で示す）でビューファインダ１０８に表示させる。図６（ｂ）は、表示順の理解を容易にするため、サムネイル画像Ｔ０４に相当するサムネイル画像２０２までしか表示されていない途中の表示状態を示している。 FIG. 6 is an explanatory diagram for explaining the operation of the thumbnail display control unit 184 when the thumbnail switching control unit 190 switches the page in the reverse direction. When the focus is moved to the thumbnail image 202 in response to a selection input to the predetermined operation key 106 by the user and the focus is switched in the reverse direction (return direction) from the thumbnail page 200 of the second page, the thumbnail switching control unit 190 switches the thumbnail page 200 from 2 pages to 1 page. Then, as shown in FIGS. 6A to 6B, the thumbnail display control unit 184 displays the thumbnail images 202 of the first thumbnail page 200 in the display order opposite to the arrangement order (FIG. 6B). ) (Indicated by a broken line arrow) is displayed on the viewfinder 108. FIG. 6B shows a display state in the middle of displaying only the thumbnail image 202 corresponding to the thumbnail image T04 in order to facilitate understanding of the display order.
　サムネイル画像２０２へのフォーカスを記録時刻の古い方に移動している場合、そのページ切換において、最初に確認したいのは前ページの一番新しいサムネイル画像２０２、即ち、モニタ右下に配置されるサムネイル画像２０２ｃである。上記サムネイル切換制御部１９０がページを逆方向に切り換えた場合、サムネイル表示制御部１８４が、サムネイル画像２０２を並び順とは逆の表示順で表示させる構成により、前ページの一番新しいサムネイル画像２０２ｃからビューファインダ１０８に表示させることができる。従って、サムネイル表示制御部１８４は、ユーザの所望するサムネイル画像２０２を適切な表示順で表示させることができるため、ユーザは、目的とするサムネイル画像２０２、ここでは一番新しい右下のサムネイル画像２０２が表示されるまで待つ必要がなく、サムネイルの検索処理の効率化とユーザの満足度の向上を図ることが可能となる。 When the focus on the thumbnail image 202 is moved to the oldest recording time, in the page switching, the first thing to check is the newest thumbnail image 202 of the previous page, that is, the thumbnail arranged at the lower right of the monitor. This is an image 202c. When the thumbnail switching control unit 190 switches the page in the reverse direction, the thumbnail display control unit 184 displays the thumbnail images 202 in the display order opposite to the arrangement order, whereby the newest thumbnail image 202c of the previous page is displayed. Can be displayed on the viewfinder 108. Therefore, since the thumbnail display control unit 184 can display the thumbnail image 202 desired by the user in an appropriate display order, the user can select the target thumbnail image 202, here the newest lower right thumbnail image 202. It is possible to improve the efficiency of the thumbnail search process and the user satisfaction.
（表示方法）
　また、上述した表示装置１００を用いて、適切な表示順でサムネイル画像２０２を表示することが可能な表示方法も提供される。 (Display method)
In addition, a display method capable of displaying the thumbnail images 202 in an appropriate display order using the display device 100 described above is also provided.
　図７は、第１の実施形態にかかる表示方法の具体的な処理を示したフローチャートである。まず、ユーザによる所定の操作キー１０６への入力に応じて、サムネイルページ２００の表示要求を受け付けると（Ｓ３００のＹＥＳ）、サムネイル生成部１８２は、所定の条件（本実施形態では記録時刻順）に従ってサムネイル画像２０２を生成する（Ｓ３０２）。そして、サムネイル表示制御部１８４は、サムネイル生成部１８２が生成した順に従った表示順で、サムネイル画像２０２をビューファインダ１０８に表示させる（Ｓ３０４）。 FIG. 7 is a flowchart showing specific processing of the display method according to the first embodiment. First, when a display request for the thumbnail page 200 is accepted in response to an input to the predetermined operation key 106 by the user (YES in S300), the thumbnail generation unit 182 follows a predetermined condition (in the order of recording time in the present embodiment). A thumbnail image 202 is generated (S302). Then, the thumbnail display control unit 184 displays the thumbnail images 202 on the viewfinder 108 in the display order according to the order generated by the thumbnail generation unit 182 (S304).
　次に、ユーザによる所定の操作キー１０６への選択入力に応じて、サムネイル切換制御部１９０がサムネイルページ２００を切換える場合、サムネイル表示制御部１８４は、サムネイルページ２００が順方向に切り換えられたか否かを判定する（Ｓ３０６）。サムネイルページ２００が順方向に切り換えられていれば（Ｓ３０６のＹＥＳ）、サムネイル生成部１８２は、新たなサムネイルページ２００のサムネイル画像２０２を並び順と同じ順で生成し（Ｓ３０８）、サムネイル表示制御部１８４は、並び順と同じ表示順でサムネイル画像２０２をビューファインダ１０８に表示させる（Ｓ３１０）。サムネイル表示制御部１８４は、１のサムネイルページ２００に表示可能なサムネイル画像２０２をすべてビューファインダ１０８に表示させたか否かを判定し（Ｓ３１２）、表示させていなければ（Ｓ３１２のＮＯ）、Ｓ３０８に戻る。１のサムネイルページ２００に表示可能なサムネイル画像２０２をすべてビューファインダ１０８に表示させていれば（Ｓ３１２のＹＥＳ）、サムネイル表示制御部１８４は、サムネイルページ２００が逆方向に切り換えられたか否かを判定する（Ｓ３１４）。 Next, when the thumbnail switching control unit 190 switches the thumbnail page 200 in response to a selection input to the predetermined operation key 106 by the user, the thumbnail display control unit 184 determines whether the thumbnail page 200 has been switched in the forward direction. Is determined (S306). If the thumbnail page 200 has been switched to the forward direction (YES in S306), the thumbnail generation unit 182 generates the thumbnail images 202 of the new thumbnail page 200 in the same order as the arrangement order (S308), and the thumbnail display control unit In step S310, the thumbnail image 202 is displayed on the viewfinder 108 in the same display order as the arrangement order. The thumbnail display control unit 184 determines whether all thumbnail images 202 that can be displayed on one thumbnail page 200 are displayed on the viewfinder 108 (S312). If not displayed (NO in S312), the process proceeds to S308. Return. If all the thumbnail images 202 that can be displayed on one thumbnail page 200 are displayed on the viewfinder 108 (YES in S312), the thumbnail display control unit 184 determines whether the thumbnail page 200 has been switched in the reverse direction. (S314).
　ここで、サムネイルページ２００が逆方向に切り換えられていれば（Ｓ３１４のＹＥＳ）、サムネイル生成部１８２は、新たなサムネイルページ２００のサムネイル画像２０２を並び順とは逆の順に生成し（Ｓ３１６）、サムネイル表示制御部１８４は、並び順とは逆の表示順でサムネイル画像２０２を表示させる（Ｓ３１８）。サムネイル表示制御部１８４は、１のサムネイルページ２００に表示可能なサムネイル画像２０２をすべてビューファインダ１０８に表示させたか否かを判定し（Ｓ３２０）、表示させていなければ（Ｓ３２０のＮＯ）、次のサムネイル画像２０２を生成する（Ｓ３１６）。 If the thumbnail page 200 has been switched in the reverse direction (YES in S314), the thumbnail generation unit 182 generates the thumbnail images 202 of the new thumbnail page 200 in the reverse order of the arrangement order (S316), The thumbnail display control unit 184 displays the thumbnail images 202 in the display order opposite to the arrangement order (S318). The thumbnail display control unit 184 determines whether or not all the thumbnail images 202 that can be displayed on one thumbnail page 200 are displayed on the viewfinder 108 (S320), and if not displayed (NO in S320), A thumbnail image 202 is generated (S316).
　そして、サムネイル表示制御部１８４は、ユーザによる所定の操作キー１０６への終了入力があるか否かを判定し（Ｓ３２２）、終了入力があれば（Ｓ３２２のＹＥＳ）、サムネイルページ２００の表示を終了する。 Then, the thumbnail display control unit 184 determines whether or not there is an end input to the predetermined operation key 106 by the user (S322), and if there is an end input (YES in S322), the display of the thumbnail page 200 is ended. To do.
（第２の実施形態：表示装置４００）
　上述した第１の実施形態では、サムネイルページ２００を順方向に切り換えた場合、サムネイル表示制御部１８４は、新たなサムネイルページ２００のサムネイル画像２０２を並び順（記録順等）と同じ表示順で表示させ、サムネイルページ２００を逆方向に切り換えた場合、新たなサムネイルページ２００（前のサムネイルページ２００）のサムネイル画像２０２を並び順とは逆の表示順で表示させることが可能な表示装置１００について説明した。 (Second embodiment: display device 400)
In the first embodiment described above, when the thumbnail page 200 is switched to the forward direction, the thumbnail display control unit 184 displays the thumbnail images 202 of the new thumbnail page 200 in the same display order as the arrangement order (recording order, etc.). When the thumbnail page 200 is switched in the reverse direction, the display device 100 that can display the thumbnail images 202 of the new thumbnail page 200 (previous thumbnail page 200) in the display order opposite to the arrangement order will be described. did.
　第２の実施形態では、サムネイル画像２０２をページ単位ではなく所定のグループ単位で順方向に順次切り換えたり、逆方向に順次切り換えたりする場合においても、サムネイル表示制御部が、ユーザの所望するサムネイル画像２０２を適切な表示順で表示させることが可能な表示装置４００について説明する。なお、上述した表示装置１００と実質的に等しい構成要素については、同一の符号を付して説明を省略する。 In the second embodiment, even when the thumbnail images 202 are sequentially switched in the forward direction or in the reverse direction in units of a predetermined group instead of in units of pages, the thumbnail display control unit performs the thumbnail image desired by the user. A display device 400 capable of displaying 202 in an appropriate display order will be described. In addition, about the component substantially equivalent to the display apparatus 100 mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted.
