Description

  The present invention relates to a recording apparatus, a recording method, and a computer program, and is particularly suitable for use in storing data recorded on an internal recording medium in an external recording medium.

  In recent years, digitalization of video and music has progressed rapidly, and the amount of data has been increasing year by year. Accordingly, recording media for storing and distributing enormous amounts of digital data such as video and music tend to increase in capacity. Such recording media for storage and distribution of digital data tend to emphasize low cost, non-contact and compatibility, and therefore, disk-type media that are optically read are becoming common.

  For example, for video, there are recording media such as a DVD (Digital Versatile Disc), an HDDVD (High Definition DVD), a BD (Blu-ray Disk), and a video CD. Further, for example, even DVDs are various, such as 8 cm, two-layer structure, and double-sided recording. The recording capacity of these recording media is finite. Therefore, it is necessary for the user to consider in advance which recording medium is used to record digital data according to the purpose. Then, by editing the recorded video so that a desired video fits on one recording medium, it is necessary to avoid a situation where a video of an important scene is recorded across a plurality of recording media. In Patent Document 1, when a long-time recording TV broadcast is recorded on a plurality of storage media, seamless recording is realized by automatically detecting a scene change and exchanging the recording medium.

  On the other hand, HDD (Hard Disk Drive) type recording media are generally used as recording media for daily use because they tend to focus on miniaturization, power saving, large capacity, access speed, random access, and rewritability. It is becoming. For example, in a stationary video recorder, digital data can be recorded on two recording media, HDD and DVD. In such a stationary video recorder, digital data is recorded on an HDD on a daily basis, and a DVD is often used for storage. In addition, devices equipped with HDDs have also appeared in portable video cameras. A video camera equipped with an HDD includes an output unit that outputs recording data for storage and distribution, and records video shot by the video camera on an optical medium using an external recording / editing device.

  As described above, in a video camera (recorder) equipped with an HDD, a program recorded on the HDD is often dubbed on a DVD for storage. In this case, the user selects a program that the user wants to save and copies it to the DVD. However, if the total data amount of programs to be dubbed is larger than the recording capacity of the DVD, all programs cannot be dubbed as they are. For this reason, it is necessary to reduce the amount of information by reducing the number of programs to be dubbed or re-encoding data decoded at the time of dubbing.

  When the number of programs to be dived is reduced, there is a problem that it becomes impossible to save all programs that the user wants to save on one disc. In addition, if re-encoding is performed, all programs may be dubbed. However, since the re-encoding process is performed in real time, it takes a very long time.

[Create new virtual disk]
When creating a new virtual disk, the user can call the screen shown in FIG. 2A by operating the operation key 4.

  FIG. 2A is a diagram showing an example of a first storage medium creation screen for the user to select the physical format of the virtual disk. In FIG. 2A, the physical formats 201 to 205 can be selected by operating the recording capacity selection key 42 in the operation key 4 which is, for example, a soft button. In the example shown in FIG. 2A, the DVD 202 is selected as the physical format. Furthermore, the display is switched to the screen shown in FIG. 2B by making a determination with the recording capacity selection key 42.

  FIG. 2B is a diagram showing an example of a second storage medium creation screen for the user to select the physical format of the virtual disk. This second storage media creation screen is a screen for performing more detailed selection of the physical format selected on the first storage media creation screen shown in FIG. In FIG. 2B, the physical formats 207 to 214 can be selected by operating the recording capacity selection key 42 in the operation key 4. The example shown in FIG. 2B indicates that “12 cm single-sided single layer” 209 is selected as the physical format. Furthermore, the display is switched to the screen shown in FIG. 2C by making a determination with the recording capacity selection key 42.

  FIG. 2C is a diagram showing an example of a storage media recording mode selection screen for the user to select the recording format of the virtual disk. This storage media recording mode selection screen is a screen for selecting a recording format that can be recorded in the physical format selected on the second storage media creation screen shown in FIG. In FIG. 2C, the recording formats 215 to 218 can be selected by operating the operation keys 4. Here, based on the free space of the HDD 6, a settable recording format is obtained in advance, only the obtained settable recording format can be selected, and the recording format that cannot be set is highlighted in advance. Thus, it is desirable to notify the user.

  In the example shown in FIG. 2C, the XP mode 215, which is one of the recording formats, cannot be selected, and the SP mode 209, which is another recording format, is selected. Indicates. In addition, it is desirable to display on the storage media recording mode selection screen what characteristics the selected recording format has. Thus, by displaying the characteristics of the selected recording format on the storage media recording mode selection screen, it is possible to give the user a reference for selecting the recording format. Further, the display is switched to the screen shown in FIG.

  FIG. 3A is a diagram showing an example of a storage media title creation screen for the user to create a title for identifying the virtual disk. This storage media title creation screen is a screen for determining the title of the virtual disk created by the above-described procedure. In FIG. 3A, the title input field 219, the OK button 220, and the edit button 221 can be selected by operating the operation key 4. In the example shown in FIG. 3A, the title “Athletic meet 2” is input in the title input field 219, and the OK button 220 indicating that the title is not changed is selected. Further, the operation key 4 determines the recording capacity, the recording format, and the title of the virtual disk. The edit button 221 is a button that is selected to change the title of the virtual disk.

FIG. 3B is a diagram showing an example of a virtual disk library display screen that is a list (of setting contents) of the virtual disks. The user selects a storage destination virtual disk from the virtual disks 222 and 223 displayed on the virtual disk library display screen. In the example shown in FIG. 3B, the virtual disk 222 is selected.
FIG. 4A shows an example of a disk replacement time setting screen for the user to set the replacement time of the virtual disk. There are two parameters to be set: “warning remaining amount (notification remaining amount)” and “end remaining amount”. Here, the recording is ended when the remaining recordable recording capacity reaches the end remaining amount. (Here, as an example, the recording capacity is shown as time). Further, when this remaining remaining amount is less than or equal to the remaining warning amount, a warning is issued to the user.

The replacement time of the virtual disk is not an item that needs to be changed frequently. Therefore, even if the specification for automatically calling the disk replacement time setting screen after determining the title for identifying the virtual disk using the storage media title creation screen shown in FIG. It does not matter if the specification is called from The virtual disk replacement time is set by using the warning remaining amount setting key 43 in the operation keys 4. In the example shown in FIG. 4A, the remaining warning amount (notification remaining amount) 224 is set to 10 minutes, and the ending remaining amount 225 is set to 1 minute.
FIG. 4B is a diagram showing an example of a warning screen displayed when the end remaining amount is equal to or less than the warning remaining amount.

<Various setting variables of virtual disk>
FIG. 5 shows an example of various variables set in the virtual disk management file for managing the virtual disk.
[Create new virtual disk]
By performing the above-described setting using the screens shown in FIGS. 2 to 4, the virtual disk management file shown in FIG. 5 can be set. The title 301 is set using the storage media title creation screen shown in FIG. The recording capacity 302 includes the first storage media creation screen shown in FIG. 2A, the second storage media creation screen shown in FIG. 2B, and the storage media shown in FIG. It is set using the media recording mode selection screen.

  As shown in FIG. 2C, 120 minutes is set as the recording capacity 302 in the above-described example. The recording time 303 is set to 0 (zero) at the time of new creation. The remaining amount of warning (remaining amount of notification) 304 and the remaining amount of completion 205 are set using the disk replacement time setting screen shown in FIG. As shown in FIG. 4A, in the above-described example, 10 minutes is set as the remaining warning amount 304, and 1 minute is set as the remaining remaining amount 305. Each time a new virtual disk is created, a virtual disk management file as shown in FIG. 5 is created. Therefore, a plurality of virtual disk management files can be created according to the number of newly created virtual disks. Also, a unique virtual disk ID 306 is created to identify the virtual disk management file.

Next, an example of the operation of the system controller 1 (microcomputer) when recording a captured image will be described with reference to the flowchart of FIG. It is assumed that one or more, preferably two or more virtual disks have been created in advance by the method described above before recording a captured image.
When the user gives an instruction to start recording a captured image using the operation key 4, the control unit 12 selects a virtual disk selected by the user from pre-created virtual disks as a virtual image recording destination. The disk is determined (step S401). The selection of the virtual disk may be performed using, for example, the virtual disk library display screen shown in FIG.

  Next, the control unit 12 determines whether or not an instruction to stop recording of a captured image is given based on the operation of the operation key 4 by the user (step S402). This instruction can be accepted periodically. When an instruction to stop recording of the captured image is given, recording of the captured image is terminated.

  On the other hand, when the stop of recording of the captured image is not instructed, the recording amount measuring unit 11 calculates the recording time as the capacity (recording amount) of the captured image to be recorded based on the information output from the recording unit 7. (Step S403). This recording time is obtained by adding the amount actually added to the value acquired from the recording time 303 shown in FIG. 5, and this added value is the virtual disk management shown in FIG. Written back to file.

  When the recording time is calculated in this way, the control unit 12 calculates the difference between the recording capacity 10 and the recording time, and obtains the remaining recording capacity in the virtual disk (external recording medium 8) (step S404). When the recording remaining amount becomes equal to or less than the ending remaining amount (step S405), the control unit 12 displays on the display device 5 that recording is ended with the current virtual disk and notifies the user (step S409). Then, the file dividing unit 13 divides the data (file) (step S410).

  If it is determined in step S405 that the remaining recording amount is greater than the ending remaining amount, the control unit 12 compares the ending remaining amount with the warning remaining amount 14 (step S406). If the end remaining amount is larger than the warning remaining amount 14, the process returns to step S401. If the end remaining amount is equal to or less than the warning remaining amount in the determination in step S406, the control unit 12 displays a warning display to the effect that the recordable remaining amount has reached the set amount on the display device 5 (step S407). ). In step S407, for example, a warning screen as shown in FIG. 4B is displayed. Then, the control unit 12 determines whether division of data (file) is instructed based on the operation of the operation key 4 by the user (step S408). In order to divide the data (file), in the present embodiment, the forced file division key 41 is assigned as a key operated by the user to divide the data (file). If there is a data (file) division instruction by the user's operation of the forced file division key 41, the process branches to step S410, and if there is no data (file) division instruction, the process returns to step S401.

  When the data (file) is divided (step S410), the control unit 12 can check a condition for creating a virtual disk which is the next recording destination, and can create a new virtual disk. It is determined whether or not (step S411). As a result of this determination, if a new virtual disk can be created, the control unit 12 creates a new virtual disk (step S413). At this time, the file is associated with the virtual disk ID 306 of the virtual disk management variable. As an association method, for example, a file name may be a virtual disk ID. On the other hand, if a new virtual disk cannot be created, the control unit 12 notifies the user to that effect (step S412) and ends the recording of the captured image.

FIG. 7 is a diagram conceptually illustrating an example of a data recording state.
When the first virtual disk 501 is recorded until the end remaining amount becomes equal to or less than the warning remaining amount (time t1), for example, a warning screen as shown in FIG. 4B is displayed on the display device 5. Thereafter, the next virtual disk 502 is created and recorded at time t2 when the forced split acceptance period has elapsed and a split instruction is issued by the user's operation of the forced file split key 41. Therefore, the DVD1 data 503 shown in FIG. 7 is divided by the user's operation. In addition, when there is no division instruction by the user's operation of the forced file division key 41, recording up to the remaining remaining amount (time t3) automatically divides the file. Therefore, the DVD2 data 504 shown in FIG. 7 is not automatically divided by the user's operation, but is automatically divided.

As described above, in the present embodiment, the user selects the virtual disk corresponding to the external recording medium 8 that is the final storage destination, and data is recorded in the recording area of the HDD 6 set as the selected virtual disk. . At this time, recording on the virtual disk (external recording medium 8) is performed using the recording capacity 302 of the virtual disk (external recording medium 8) selected by the user and the current recording amount measured by the recording amount measuring unit 11. The remaining amount is calculated, and the data (file) is divided into a plurality when the remaining recording amount is equal to or less than a predetermined remaining amount or when an instruction is given by the user. Thereafter, the divided data is transferred to an external recording device and recorded on the external recording medium 8 by the external recording device.
As described above, since the capacity of data that can be recorded is determined according to the virtual disk selected by the user, the user has knowledge of the capacity of the external recording medium 8 to be finally recorded for storage or distribution. Even if it does not have it, it becomes possible to take a picture while taking into account the capacity of the external recording medium 8 to be finally recorded.

Further, since the recording amount measuring unit 11 measures the data amount of the data to be actually recorded, the data amount is not physically limited by the capacity of the medium or the area as in the prior art, The recording capacity can be changed flexibly.
Further, since the control unit 12 calculates the recordable data amount as the remaining recording amount, the user can feel as if the data is virtually recorded on the external recording medium 8 and the remaining amount is recorded. Control according to the amount becomes possible. In addition, since data can be recorded in an area that is not physically limited, if the recording capacity of the selected virtual medium is excessive, the virtual medium can be reused.

  In addition, when the recording remaining amount is equal to or less than the ending remaining amount, or when an instruction is given by the user, the data (file) is divided into a plurality of parts, so that the external recording device connected to the digital video camera takes the initiative. Thus, the divided data (file) can be transferred to the external recording device. Furthermore, since the user intentionally divides the recording, data can be recorded under the initiative of the user.

Further, since the data (file) is automatically divided when the remaining amount reaches a predetermined amount, the user can concentrate on recording with peace of mind. Further, since the warning is given when the remaining recording amount falls below a certain amount, the user can concentrate on recording. Further, since the user can set the remaining amount for displaying the warning, the warning according to the photographing condition can be performed.
Since the HDD 6 is used as a medium for recording captured images in the digital video camera, the recording medium in the digital video camera is reduced in size, power consumption, large capacity, high access speed, and random accessibility are ensured. be able to.

  In this embodiment, a plurality of virtual disks are created in advance, and a storage destination virtual disk is selected from the created virtual disks at the time of program recording (including scheduled recording). A new virtual disk may be created when the capacity of one virtual disk becomes full.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the first embodiment described above, data (file) is divided when recording inside the digital video camera. On the other hand, in this embodiment, data (file) division information is recorded in a division management file, and the data (file) is divided when the data (file) is transferred by connecting to an external recording device. ing. That is, in the first embodiment, data (file) is divided at the time of recording inside the digital video camera, but in this embodiment, data (file) is divided at the time of recording data dubbing. Thus, the present embodiment and the first embodiment described above differ only in part of the method for dividing data (file). Therefore, in the following description, the same parts as those in the first embodiment described above are denoted by the same reference numerals as those in FIGS.

<System configuration>
FIG. 8 is a block diagram showing an example of the configuration of the recording apparatus of the present embodiment.
In FIG. 8, the recording apparatus of the present embodiment includes a system controller 81, a camera 2, a recording unit 7, an operation key 4, a display device 5, an HDD 6, and the like. The system controller 1 of the recording apparatus shown in FIG. 1 has a file dividing unit 13, but the system controller 81 of the recording apparatus of this embodiment has a division information creating unit 15.

The division information creation unit 15 records the division information of data (file) in the division management file. Then, after data recording is completed, when data is transferred to the external recording device, the data (file) is divided according to the created division management file, and the data is transferred to an external recording device (not shown). The transferred data is recorded on the external recording medium 8 by the external recording device.
The various virtual disk setting screens are the same as those shown in FIGS. 2 to 4, and the various virtual disk setting variables are the same as those shown in FIG. Omitted.

  An example of the operation of the system controller 1 (microcomputer) when recording a captured image will be described with reference to the flowchart of FIG. As in the first embodiment, it is assumed that one or more virtual disks are created in advance before recording a captured image. Further, steps S601 to S609 and S612 to S614 in FIG. 9 are the same processes as steps S401 to S409 and S411 to S413 in FIG.

When the user starts recording a captured image with the operation key 4, the control unit 12 uses a virtual disk selected by the user from among virtual disks created in advance as a virtual disk that is a recording destination of the captured image. Determine (step S601)
Next, the control unit 12 determines whether or not an instruction to stop recording of the captured image is given based on the operation of the operation key 4 by the user (step S602). When stop of recording of the recorded image is instructed, recording of the captured image is terminated.

  On the other hand, when the stop of recording of the captured image is not instructed, the recording amount measuring unit 11 calculates the recording time (step S603). Next, the control unit 12 calculates the difference between the recording capacity 10 and the recording time and obtains the remaining recording capacity (step S604). When the recording remaining amount becomes equal to or less than the ending remaining amount (step S605), the control unit 12 notifies the user of ending the current virtual disk recording (step S609).

Next, the division information creation unit 15 acquires the time code of the external recording medium 8 (step S609). Next, the division information creation unit 15 records the acquired time code as division information in the division management file (step S611).
Next, the control unit 12 determines whether or not a new virtual disk can be created (step S612). If the result of this determination is that a new virtual disk can be created, the controller 12 creates a new virtual disk (step S614). On the other hand, if a new virtual disk cannot be created, the control unit 12 notifies the user to that effect (step S613) and ends the recording of the captured image.

  If it is determined in step S605 that the remaining recording amount is greater than the ending remaining amount, the control unit 12 compares the ending remaining amount with the warning remaining amount 14 (step S606). If the end remaining amount is larger than the warning remaining amount 14, the process returns to the determination in step S601. If it is determined in step S605 that the remaining remaining amount is equal to or less than the warning remaining amount, the control unit 12 displays a warning display on the display device 5 that the recordable remaining amount has reached the set amount (step S607). ). Then, the control unit 12 determines whether division of data (file) has been instructed based on the operation of the operation key 4 by the user (step S608). If there is a data (file) division instruction by the user's operation, the process branches to step S610 described above. If there is no data (file) division instruction, the process returns to step S601.

  As described above, in the present embodiment, the division information creation unit 15 records the division information of the recording data in the division management file and transfers the data (file) according to the created division management file when transferring the data to the external recording device. Since the data is transferred to the external recording device, in addition to the effects of the first embodiment, it is possible to avoid having to have a large number of data divided according to the number of data divisions. The effect is that it can be managed more easily.

  It is to be noted that a method for recording division information as chapter information in an IFO file is widely known, and chapter information may be used as division information. In such a case, general chapter information and a disc are used. In order to clearly separate and manage the division information, it is preferable to manage the division information using a dedicated file set separately.
