<First Embodiment>
A first embodiment of the present invention will be described.
First, the recording operation in the recording / reproducing apparatus 100 of this embodiment will be described with reference to FIG. FIG. 2 is a flowchart for explaining identification information creation processing for creating identification information of a moving image file, representative image creation processing for creating a representative image of a moving image file, and the like. ing. In the present embodiment, a recording apparatus capable of recording one content on three recording media is used. The recording medium selected by the user as the recording destination is defined as the first recording medium (built-in memory 108). The recording medium selected as the first relay recording destination is the second recording medium (first external recording medium 113), and the recording medium selected as the second relay recording destination is the third recording medium (second recording medium). External recording medium 114).

  First, when the start of recording is instructed by a user operation, the main control unit 101 starts recording a relay moving image in the built-in memory 108 (S201). At this time, the main control unit 101 performs relay record information creation processing (S202). The created relay recording information (relay recording ID, relay recording number, relay recording order number, recording medium ID, file number, representative image) is recorded in the recording medium (nonvolatile memory 103). Details of the relay recording information will be described later with reference to FIG.

  Then, while recording in the built-in memory 108, it is determined whether the remaining recordable time based on the current free space in the built-in memory 108 and the image quality setting of the relay moving image being recorded is greater than or equal to a predetermined threshold (S203). ). If it is greater than or equal to the threshold value, it is determined whether or not recording stop is instructed by a user operation (S204). If an instruction to stop recording is given, the recording is stopped (S205), and the control according to this flowchart is stopped.

  If the remaining recordable time in the built-in memory 108 is less than the predetermined threshold, recording in the built-in memory 108 is stopped and the process proceeds to S206. In S206, it is determined whether or not the first external recording medium 113, which is the second recording medium, is mounted on the first recording medium mounting unit 109. If it is mounted, the process proceeds to S207 to start recording on the first external recording medium 113. This stops recording on the recording medium in which the relay moving image has been recorded until now, and starts recording on another recording medium. Hereinafter, this operation is referred to as relay recording control. At this time, the main control unit 101, as a continuation of the relay recording information of the relay recording ID recorded in S202, information on the relay file to be recorded on the first external recording medium 113 (relay recording order number, recording medium ID, file Number, representative image). Then, it is recorded in the nonvolatile memory 103 (S208). Also, 1 is added to the relay recording number.

  Thereafter, as in S203, S204, S207, and S208, whether or not the remaining recordable time of the first external recording medium 113 is equal to or greater than a predetermined threshold while performing recording on the first external recording medium 113. Determine (S209). If it is greater than or equal to the threshold value, it is determined whether or not recording stop is instructed by a user operation (S210). If an instruction to stop recording is given, the recording is stopped (S205), and the control according to this flowchart is stopped. In the determination of S209, if the remaining recordable time of the first external recording medium 113 is less than a predetermined threshold, a relay-recordable recording medium, in this case, the second external recording medium 114 is loaded. It is determined whether or not there is (S206).

  If it is mounted, recording on the first external recording medium 113 is stopped, and recording on the second external recording medium 114 is started (S207). At this time, the main control unit 101, as a continuation of the relay recording information of the relay recording ID of the currently recorded relay video, information on the relay file to be recorded on the second external recording medium 114 (relay recording order number, recording (Media ID, file number, representative image). Then, it is recorded in the nonvolatile memory 103 (S208). Also, 1 is added to the relay recording number.

  Thus, one content (relay moving image) is continuously recorded on a plurality of recording media. If it is determined in S209 that the remaining recordable time of the second external recording medium 114 is less than the predetermined threshold value, or if it is determined in S210 that recording stop is instructed by a user operation, the second external recording medium 114 The recording to is stopped, and the control according to this flowchart is stopped. Here, the relay record information is created at the start of recording or at the time of relay recording. For example, when the relay recording is not performed, the relay record ID is changed. You may make it.

Here, the relay recording information created in S202 and S208 will be described with reference to FIG.
FIG. 3 is a diagram illustrating an example of the relay recording information recorded on the relay recording information medium (nonvolatile memory 103). As a whole configuration, for each relay recording ID (301), one relay recording number (302), relay recording order number (303), recording medium ID (304), file number (305), the number of relay recordings, It consists of a set of representative images (306).

  The relay recording ID (301) guarantees the relationship between image data when one relay moving image is recorded on a plurality of recording media. One relay record ID (301) is used until recording is started by user operation and recording is stopped. When one relay moving image is recorded on one recording medium, an invalid relay recording ID (301) such as “0” may be assigned.

The relay recording number (302) is a number indicating the number of recording media in which one relay moving image is recorded.
The relay recording order number (303) is information indicating the number of the entire relay-recorded file (each moving image file constituting the relay moving image) recorded on the recording medium.

  The recording medium ID (304) is information given so as to be unique for each recording medium. In the case of a removable recording medium such as a memory card, the information is determined by the main control unit when it is first inserted into the recording medium or formatted. When individual IDs are written in all of the standards, or when an identification means such as a wireless ID tag is provided, it may be used.

The file number (305) is a number indicating the relay file recorded on the recording medium among the relay files recorded in the relay.
The representative image (306) is an image representing a relay moving image to be recorded on the recording medium at the start of recording and at the time of relay recording. The first frame may be a representative image, or a characteristic frame may be a representative image.

  Based on these relay recording information, how many relay movies are relay-recorded, how many relay media are recorded in one relay movie, and in what order in which recording media You can manage what has been done.

  As described so far, by controlling the flowchart of FIG. 2, it is possible to manage how many relay moving images are relay-recorded. In addition, it is possible to manage how many recording media the one relay moving image is recorded on, and in what order and on which recording medium.

Next, the operation at the time of reproduction in the recording / reproducing apparatus 100 of the present embodiment will be described with reference to FIG.
FIG. 4 is a flowchart for explaining the operation during reproduction. In the present embodiment, it is assumed that one content (one relay moving image) is recorded on three recording media. When the relay recording is performed, the first recording medium is the internal memory 108 (first recording medium), the next recording medium is the first external recording medium 113 (second recording medium), and then The recorded recording medium is a second external recording medium 114 (third recording medium). Furthermore, a case will be described in which one recording medium is selected from a plurality of recording media and a representative image of a moving image file recorded on the selected recording medium is displayed on the same screen.

First, the main control unit 101 acquires a file number and a representative image of an image file (moving image or still image) to be displayed from the selected recording medium (S401).
Next, it is determined whether or not the acquired image file is a moving image file (relay file) recorded by relay (S402).

  If it is a relay-recorded moving image file, information on the relay file included in the same relay record ID is acquired from the relay record information recorded in the nonvolatile memory 103 (S403). Then, the representative image of each acquired relay file is displayed (S404).

If the result of determination in S402 is not a relay-recorded moving image file, a representative image of the moving image file acquired from the selected recording medium is displayed (S405).
After the process of S404 or S405, it is determined whether or not the display for one page is finished in S406. If it is not the end, the process returns to S401 and the above-described operation is repeated. In the case of the end, the process of FIG. 4 is terminated.

Next, the process performed in S402 for determining whether the image file is a moving image file recorded by relay will be described in detail.
First, it is obtained by referring to the recording medium ID of the recording medium and the file number of the moving image file on the recording medium. Then, it is searched whether the recording medium ID of the relay recording information and the set of the file number match. This is determined for all combinations of a plurality of recording medium IDs and file numbers managed by one relay recording ID.

  Relay recording is performed a plurality of times, and when there are a plurality of relay recording IDs, determination is made for each relay ID. As a result, when the combination of the recording medium ID and the file number matches, it can be determined that the moving image file is a relay recorded moving image file. Conversely, if they do not match, it can be determined that the video file is not a relay-recorded video file. At this time, the relay recording ID including the recording medium ID and the file number that match is acquired.

Next, the process of displaying representative images in the order of relay recording performed in S404 will be described in detail.
The representative images recorded in the moving image file acquired in S401 are displayed for the number of relay recordings in order from the lowest relay recording order number.

  In S405, a representative image created in advance may be displayed, or a representative image may be created and displayed from a moving image file.

Next, FIG. 5 shows an example of a display screen of the recording medium when the control described in the flowchart of FIG. 4 is performed.
In FIG. 5, an icon 501 indicates that a moving image file has been relay-recorded. An icon 502 indicates that the moving image file is relay-recorded and recorded in the built-in memory 108. The icon 503 indicates that the moving image file is relay-recorded and recorded on the first external recording medium 113. The icon 504 indicates that the moving image file is relay-recorded and recorded on the second external recording medium 114.

The representative image 505 and the representative image 509 are not relay-recorded moving image files but indicate moving image files that are recorded completely on the recording medium.
Since the representative image 506 displays the icon 501 and the icon 502, it can be seen that the representative image 506 is a part of the moving image file that is relay-recorded and is recorded in the built-in memory 108. Further, it can be seen from the display position of the representative image 507 and the representative image 508 that the first portion of the image data recorded separately on the three recording media.

  Since the representative image 507 displays the icon 501 and the icon 503, it can be seen that the representative image 507 is a part of the moving image file that has been relay-recorded and is recorded on the first external recording medium 113. Furthermore, it can be seen from the display positions of the representative image 506 and the representative image 508 that the second portion of the image data recorded separately on the three recording media.

  Since the icon 501 and the icon 504 are displayed on the representative image 508, it can be seen that the representative image 508 is a part of the moving image file that is relay-recorded and is recorded on the second external recording medium 114. Further, it can be seen from the display positions of the representative image 506 and the representative image 507 that the third portion of the moving image files recorded on three recording media is recorded.

As described so far, it is possible to recognize how many movie files are relay-recorded by controlling the flowchart of FIG. In addition, it is possible to easily recognize how many recording media are recorded on one relay-recorded moving image file, and in what order and on which recording medium.
In the embodiment described above, relay recording on three recording media has been described. However, the number of recording media is not limited as long as it is two or more.

<Second Embodiment>
A second embodiment of the present invention will be described.
Since the recording operation in this apparatus is the same as the recording operation in the first embodiment, a detailed description thereof will be omitted.
The operation during reproduction in this apparatus will be described with reference to FIG. FIG. 6 is a flowchart for explaining the operation at the time of reproduction, and has a processing procedure from S601 to S612.

  In the present embodiment, a description will be given assuming that one content (one relay moving image) is recorded on three recording media. When the relay recording is performed, the first recording medium is the internal memory 108 (first recording medium), the next recording medium is the first external recording medium 113 (second recording medium), and then the recording is performed. The recorded recording medium is set as a second external recording medium 114 (third recording medium). Further, a case will be described in which one recording medium is selected from a plurality of recording media and a representative image of image data recorded on the selected recording medium is displayed on the same screen.

First, the main control unit 101 acquires a file number and a representative image of an image file (moving image or still image) to be displayed from the selected recording medium (S601).
Then, it is determined whether or not the acquired image file is a moving image file recorded by relay (S602).
If it is a relay-recorded moving image file, a process of setting the relay recording order number n to an initial value (n = 1) is performed (S603).

  Next, from the relay record information recorded in the nonvolatile memory 103, information on the relay file included in the same relay record ID and having the relay record order number n is acquired (S604).

  Next, it is determined whether or not the recording medium with the recording medium ID is accessible. At this time, the determination is made based on signals from the first mounting detection unit 111 and the second mounting detection unit 112 (S605). If the access is impossible, an icon indicating that is displayed and a representative image acquired from the relay record information is displayed (S606). If the recording medium is accessible, it is determined whether the relay file body recorded on the recording medium is accessible (S607). If access is not possible, a message indicating that access is not possible is displayed, and a representative image acquired from the relay record information is displayed (S608).

If the relay file recorded on the recording medium is accessible, the representative image created in association with the recording medium ID acquired from the relay recording information is displayed (S609).
Next, it is determined whether all the representative images of the relay file included in the same recording ID have been displayed (S610). If all the representative images are not displayed, the relay recording order number n is incremented by 1 (S611), and the process returns to S604. If it is determined in step S602 that the image file is not relay-recorded, the representative image acquired from the selected recording medium is displayed, and then the process proceeds to step S613 (S612). The representative image may be displayed as a representative image created in advance.
It is determined whether the display of one page has been completed (S613). Until it is determined that the display process is completed, the processes from S601 to S613 are performed several times, and the control according to this flowchart is stopped when the display process is completed. .

Next, the process performed in S602 for determining whether the moving image file has been relay-recorded will be described in detail.
First, the recording medium ID of the recording medium and the file number of the moving image file on the recording medium are acquired. Then, a search is made as to whether or not the set of the recording medium ID and file number of the relay recording information matches. This is determined for all combinations of a plurality of recording medium IDs and file numbers managed by one relay recording ID.

  Relay recording is performed a plurality of times, and when there are a plurality of relay recording IDs, determination is made for each relay ID. As a result, when the combination of the recording medium ID and the file number matches, it can be determined that the moving image file is a relay recorded moving image file. On the other hand, if they do not match, it can be determined that the video file is not relay-recorded. At this time, the relay recording ID including the recording medium ID and the file number that match is acquired.

Next, the process for determining whether or not the recording medium is accessible in S605 will be described in detail.
First, the number of times of processing for the relay recording ID acquired in S604 is obtained, and the relay recording order number of the relay recording information is searched using the number of times as a key. Then, the recording medium ID recorded in the array in which the number of processings and the relay recording order number match is acquired. It is determined whether or not the recording medium indicated by the acquired recording medium ID is accessible.

  Here, when the recording medium is not mounted or when the recording medium is mounted but not electrically connected, it is determined that the recording medium is inaccessible when some sort of failure occurs. At this time, the retrieved relay recording order number is acquired.

Next, a detailed description will be given of the display processing performed in S606 to the effect that the recording medium cannot be accessed.
First, a representative image associated with each relay file is displayed, and an icon is displayed as a display process indicating that the recording medium cannot be accessed. Instead of the icon, display processing such as making the representative image black, displaying gray, or not displaying the representative image may be performed.

Next, the process performed in S607 for determining whether or not the relay file main body can be accessed will be described in detail.
First, the file number associated with the relay recording order number acquired in S604 is acquired. It is determined whether or not the moving image file indicated by the acquired file number is accessible. Here, it is determined that access is not possible, for example, if the moving image file has been deleted or has been set so that it cannot be read.

Next, the display process performed in S608 to the effect that the relay file cannot be accessed will be described in detail.
First, an indication that the relay file cannot be accessed is displayed. Next, the representative image acquired from the relay record information is displayed, and an icon is displayed as a display process indicating that the relay file cannot be accessed. Instead of the icon, display processing such as making the representative image black, displaying gray, or not displaying the representative image may be performed.

Next, the process performed in S610 for determining whether all the representative images of the relay file included in the same recording ID have been displayed will be described in detail.
The number of relay records in the relay record ID acquired in S604 is compared with the relay record order number acquired in S601. If the relay recording number is larger than the relay recording order number, it is determined that all the relay files are not displayed, and the process proceeds to S604. On the other hand, if the number of relay recordings is the same as or smaller than the relay recording order number, it is determined that all relay files have been displayed.

Next, FIG. 7 shows an example of the display screen of the recording medium when the control of the flowchart of FIG. 6 is performed.
In FIG. 7, an icon 701 indicates that a moving image file has been relay-recorded. An icon 702 indicates that the moving image file is relay-recorded and recorded in the built-in memory 108. An icon 703 indicates that the moving image file is relay-recorded and recorded on the first external recording medium 113. An icon 704 indicates that the moving image file is relay-recorded and recorded on the second external recording medium 114. An icon 705 indicates that the recording medium cannot be accessed. An icon 706 indicates that the moving image file cannot be accessed.

The representative image 707 and the representative image 711 are not relay-recorded moving image files but indicate moving image files that are recorded completely on the recording medium.
Since the icon 701 and the icon 702 are displayed on the representative image 708, it can be seen that the representative image 708 is a part of the relay-recorded moving image file and is recorded in the built-in memory 108 as the recording medium. Furthermore, it can be seen from the display positions of the representative image 709 and the representative image 708 that the first portion of the moving image files recorded on three recording media is recorded.

  Since the representative image 709 displays the icon 701, the icon 703, and the icon 705, the representative image 709 is a part of the moving image file that is relay-recorded, and is recorded on the first external recording medium 113 instead of the built-in memory 108. Indicates. It can also be seen that access is not possible because the first external recording medium 113 is not loaded. Furthermore, it can be seen from the display positions of the representative image 708 and the representative image 710 that the second portion of the moving image file is recorded separately on the three recording media.

  Since the icon 701, icon 704, and icon 706 are displayed, the representative image 710 is a part of the relay-recorded moving image file and is recorded in the second external recording medium 114 instead of the built-in memory 108. I understand. Furthermore, it can be seen that access is not possible due to reasons such as the deletion of the moving image file in the second external recording medium 114. Furthermore, it can be seen from the display positions of the representative image 708 and the representative image 709 that this is the third part of the moving image file recorded separately on the three recording media.

Next, another example of the display screen of the recording medium when the control of the flowchart of FIG. 6 is performed is shown in FIG.
A display area 805 is an example of a screen that displays a list of representative images of a moving image file for each date, for example. The representative images 806, the representative image 807, the representative image 808, and the representative image 809 are recorded in the order of the representative images.

  For the representative image 807, the representative image 808, and the representative image 809, the display area overlaps with the previous representative image. Here, for the purpose of explanation, the representative image 807a is described as an overall image of the representative image 807, the representative image 808a is described as the entire image of the representative image 808, and the representative image 809a is described separately as the entire image of the representative image 809.

  An icon 801 indicates that the moving image file has been relay-recorded. An icon 802 indicates that the moving image file is relay-recorded and recorded in the built-in memory 108. An icon 803 indicates that the moving image file is relay-recorded and recorded on the first external recording medium 113. An icon 804 indicates that the moving image file is relay-recorded and recorded on the second external recording medium 114.

The representative image 806 is not a moving image file recorded by relay, but a moving image file recorded completely on the recording medium.
Since the icon 801 and the icon 802 are displayed on the representative image 807a, it can be seen that the representative image 807a is a part of the moving image file that is relay-recorded and is recorded in the built-in memory 108 that is the recording medium. Furthermore, it can be seen from the display positions of the representative image 808 and the representative image 809 that it is the first part of the moving image file recorded separately on the three recording media.

  The representative image 808a is displayed with an icon 801, an icon 803, and an overall light gray. For this reason, it is a part of a moving image file recorded by relay, is recorded on the first external recording medium 113 instead of the recording medium, and is not accessible because the first external recording medium 113 is not mounted. It turns out that it is. Furthermore, it can be seen from the display position of the representative image 807 and the representative image 809 that it is the second part of the moving image file recorded separately on the three recording media.

  The representative image 809a is displayed with an icon 801, an icon 804, and a dark gray as a whole. For this reason, it is a part of the moving image file recorded by the relay, recorded in the second external recording medium 114 instead of the recording medium, and the moving image file is deleted in the second external recording medium 114. It turns out that it is inaccessible for a reason. Furthermore, it can be seen from the display positions of the representative image 807 and the representative image 808 that the third portion of the moving image files recorded on three recording media is recorded.

  By controlling the flowchart of FIG. 6 described so far, it is recognized how many moving image files are relay-recorded and how many recording media are recorded on one relay-recorded moving image file. It is possible. In addition, it is possible to easily recognize in which order the recording media are recorded and whether each recording medium or moving image file is accessible. Furthermore, it can also be displayed so that it can be identified whether or not it is currently in a reproducible state.

In the embodiment described above, relay recording on three recording media has been described. However, the number of recording media is not limited as long as it is two or more.
Note that the relay recording information may be recorded on all recording media for recording moving image data. As a way, do not use up the entire capacity for each recording medium, leave a predetermined capacity for the relay recording information, and record the relay recording to the next recording medium, complete the relay recording information when recording of the video is stopped, Record on all recording media. In this way, even when the playback is performed by another device during playback, the information of the relay moving image composed of a plurality of moving image files recorded on any other recording medium can be found by looking at only one recording medium.

For example, the information regarding the moving image file recorded on the recording medium that is not loaded at the time of reproduction is acquired by referring to the relay recording information recorded on the recording medium. Then, it is possible to display on the same screen as described above so that the order in which the moving image file of the relay moving image recorded on the recording medium other than the recording medium currently read by the reproducing unit is recorded can be understood. It becomes possible.
The above-described flowcharts of FIGS. 4 and 6 describe the display procedure for one page (one screen) of multi-display. However, if the page is switched, the process is performed again.
