Description

  The present invention relates to a playback apparatus, a playback apparatus control method, a program, and a storage medium, and more particularly to a technique suitable for use in playback of image data from a recording medium on which a plurality of scenes are recorded.

  Conventionally, a digital video camera, a digital camera, a mobile phone, and the like can shoot a subject, record it as moving image data or still image data on a disk-shaped medium, a hard disk, a flash memory, and the like and reproduce it. In such an apparatus, the moving image data recorded during the recording start operation and the recording stop operation can be recorded as one scene.

FIG. 3A is a diagram showing a state in which three scenes are recorded in order from the first scene on the recording medium.
As shown in FIG. 3A, when reproducing image data recorded on a recording medium, scene 1 to scene 2 and scene 3 are reproduced in the order of recording. At this time, the joints from scene 1 to scene 2 and from scene 2 to scene 3 are seamlessly reproduced, and the process immediately transitions to reproduction to a scene with a different recording date and time.

  For example, even if the viewer wants to see the scene he was watching at the end of the scene 2, the viewer may have shifted to the playback of the scene 3. In that case, it is necessary to perform a pause operation to enter a pause state and search for a desired image by reverse playback or reverse search. Alternatively, a playback stop operation must be performed, and as shown in FIG. 7, an image indicating the recorded index of each scene is displayed, and the scene 2 must be selected and played back. In this way, a predetermined operation is required to view a desired image.

  In particular, as shown in FIG. 3B, when many scenes with a short recording time of several seconds are recorded, each scene is switched and reproduced seamlessly within a few seconds. Therefore, even if the viewer finds a desired image, several scenes may have already been reproduced at the stage of operation. When searching from the index screen, a desired scene is not always displayed on the switched index screen. Therefore, it is necessary to search for a desired image by performing screen feed, scene selection, reproduction, search, etc., and the operation becomes further complicated.

  In order to solve such a problem, for example, in Patent Document 1, in order to view a climax scene from a DVD on which a movie is recorded, when searching by fast-forward playback (search), the title is reached when it comes to the end of the title. There has been proposed a technique for pausing without ending. According to this technique, since a pause is made at the end of the title, the viewer can then easily search for a desired scene by performing reverse playback and reverse search, and can play back and view it.

JP 2005-150871 A

  However, in the technique described in Patent Document 1, only fast-forward playback (search) is performed and paused at the end of the title, that is, a scene that is sequentially played back from the recording medium is paused at the last played scene. To do. On the other hand, when it is composed of a plurality of scenes such as a video photographed by a video camera, it cannot be grasped when a desired scene is reproduced. If fast-forward playback is performed in such a case, a desired scene may be passed.

  Therefore, when the viewer wants to repeatedly reproduce a desired scene, or when he / she wants to reproduce from the beginning of a scene shot on the same date, he / she has to perform reverse reproduction and reverse search to find and reproduce the beginning of the scene. In this way, many operations are required because the scene must be searched, and the waiting time cannot be shortened sufficiently.

  In addition, when it is desired to immediately edit the reproduced scene, it is necessary to search for the target scene after pausing and switch to the edit mode by performing menu display or the like. Thus, there is a problem that many operations are required.

  An object of the present invention is to make it possible to easily search for a desired scene from a recording medium on which a plurality of scenes are recorded.

  The playback apparatus according to the present invention includes a playback unit that plays back a first scene from a first recording medium on which a plurality of scenes are recorded, and a display control that displays the first scene played back by the playback unit on the display unit. Means for acquiring management information relating to the first scene reproduced by the reproducing means, and based on the management information acquired by the acquiring means, the reproducing means follows the first scene. Control means for controlling the display control means to display the first scene and the second scene on the same display screen of the display means when starting the reproduction of the second scene to be reproduced. It is characterized by comprising.

  According to the present invention, the viewer can easily confirm the break of the scene. Thereby, a viewer can easily search for a desired scene.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration example of a recording / reproducing apparatus 10 according to the present embodiment.
In FIG. 1, a recording / reproducing apparatus 10 includes an imaging unit 100 including an imaging element such as a CCD, a camera signal processing circuit 101 that performs camera signal processing, and an encoding circuit that encodes moving image data and reduces the amount of information. 102. Furthermore, a recording circuit 103 for recording moving image data or the like on the recording medium 104, a management information generating circuit 105 for generating management information of a scene to be recorded on the recording medium 104, and a memory 106 shared by each block are provided. Furthermore, a reproduction circuit 107 that reproduces a signal from the recording medium 104, a decoding circuit 108 that decodes the reproduced encoded data, a display circuit 109 that processes data for display, and a display device 110 such as an LCD are provided. Further, a management information acquisition circuit 111 that acquires management information of a scene recorded in the recording medium 104, a command from the operation switch 113 can be input, a control circuit 112 that controls each block, an operation switch 113, and a mode A setting circuit 114 is provided. These blocks are connected via a bus 115.

  When the operator operates the operation switch 113 to give a shooting instruction, information on the shooting instruction is input from the operation switch 113 to the control circuit 112, and the control circuit 112 sets each block to the recording mode.

  The imaging unit 100 photoelectrically converts image information input from a lens (not shown) and sends it to the camera signal processing circuit 101. The camera signal processing circuit 101 performs AD conversion on the photoelectrically converted image information, performs luminance / color difference extraction, WB, γ correction, contour correction, and the like, and stores camera signal processed moving image data in the memory 106.

  The encoding circuit 102 reads out the moving image data subjected to the camera signal processing by the camera signal processing circuit 101 from the memory 106, for example, MPEG-2 system, H.264, etc. The compression process is performed by the H.264 method or the like. Then, the encoding circuit 102 stores the encoded moving image data in the memory 106.

  The recording circuit 103 reads out the moving image data encoded by the encoding circuit 102 from the memory 106, adds an error correction code for recording on the recording medium 104, performs modulation for recording, and records the recording medium 104. To record.

  When the management information generation circuit 105 receives a shooting instruction from the control circuit 112, the scene number of the currently recorded scene, the date and time information of shooting start, and the size information of the moving image to be recorded as shown in FIG. Is stored in the memory 106 as management information A. Further, as shown in FIG. 9B, the management information generation circuit 105 creates offset address information from the head of the recording medium 104 of each frame of the recorded moving image data, and stores it in the memory 106 as management information B. Remember.

  In the present embodiment, a series of moving image data recorded between the recording (shooting) start instruction and the recording stop instruction by the operator is managed as one scene, and the moving image data of one scene is also managed. Record as one video file.

  When the operator operates the operation switch 113 to give an instruction to stop shooting, information on the shooting stop instruction is input from the operation switch 113 to the control circuit 112, and the control circuit 112 sets each block to the recording stop mode. Then, the recording circuit 103 stops the recording of the moving image data on the recording medium 104 in response to the shooting stop instruction. Then, the recording circuit 103 records the management information A as shown in FIG. 9A stored in the memory 106 as the management file A on the recording medium 104. Further, the recording circuit 103 records the management information B as shown in FIG. 9B stored in the memory 106 in association with the recorded scene as a management file (B-1).

  As described above, a plurality of scenes and management information of each scene are recorded on the recording medium 104 as shown in FIG. In this embodiment, it is assumed that scenes 1 to N are recorded.

  In the present embodiment, when the moving image data of a scene is reproduced from the recording medium 104, when shifting to the reproduction of the next scene, the current scene and the next scene are displayed on the same display screen (hereinafter referred to as a review reproduction mode). And normal playback mode (hereinafter referred to as seamless playback mode). The operator can switch and set the playback mode to any mode by operating the operation switch 113. For example, when the review playback mode is set, the mode setting circuit 114 sets the playback mode to the review playback mode in which the current scene and the next scene are displayed on the same display screen based on an input signal from the operation switch 113.

Next, the operation in the playback mode will be described.
When reproduction instruction information is input from the operation switch 113 to the control circuit 112, the control circuit 112 sets each block to the reproduction mode. At this time, the playback mode set by the mode setting circuit 114 is selected from among the playback modes described above.

  The reproduction circuit 107 reads the management file A recorded on the recording medium 104, and the management information acquisition circuit 111 stores it as management information A in the memory 106. Then, based on the management information A stored in the memory 106, the playback circuit 107 reads representative image data of a predetermined number of scenes from the last photographed scene N from the recording medium 104 and stores them in the memory 106. Here, the representative image data is generated by reproducing the first frame in the scene. When the representative image data in the scene is recorded in advance on the recording medium 104, the representative image data is read out.

  Next, the decoding circuit 108 decodes the representative image data of each scene stored in the memory 106 and stores the decoded representative image data in the memory 106. The display circuit 109 functions as a display unit, reads the decoded representative image data stored in the memory 106, converts it into a display size, and as a representative image of each scene as shown in FIG. It is displayed on the display device 110. In this embodiment, as shown in FIG. 10A, representative image data of six scenes (scene N to scene (N-5)) including the last photographed scene are displayed on the display device 110. .

  In FIG. 10A, a scene selection frame 1000 is displayed on the representative image of the scene N, but the operator operates the operation switch 113 to move the selection frame 1000 to select a scene to be reproduced. be able to. Further, by moving the selection frame 1000, the page of the representative image list screen can be changed as shown in FIG. When the page of the list screen is updated, the control circuit 112 controls each circuit to reproduce and display the representative image data for the next six scenes based on the management information A.

  Next, an example in which the operation switch 113 is operated by the operator and the scene K is selected in the state shown in FIG. 10B will be described. The control circuit 112 receives an input signal from the operation switch 113, and the reproduction circuit 107 reads the management file (BK) of the selected scene K from the recording medium 104 and stores it in the memory 106. Then, the reproduction circuit 107 sequentially reads the moving image data of the scene K from the recording medium 104 and stores it in the memory 106.

  The decoding circuit 108 reads the moving image data of the scene K stored in the memory 106, performs decoding processing according to the encoding format, and stores the decoded moving image data in the memory 106. The display circuit 109 reads out the moving image data decoded by the decoding circuit 108 from the memory 106, changes the size of the screen (reduces), and sends it to the display device 110. The display device 110 displays the moving image of the scene K. To do.

  Here, when the seamless playback mode is selected, when playback is performed to the end of the scene K, the moving image data of the next photographed scene K + 1 is subsequently played back from the recording medium 104, decoded, and displayed.

Next, the review playback mode process will be described. FIG. 4 is a flowchart illustrating an example of a processing procedure in the review reproduction mode. In the present embodiment, a case where the scene K is reproduced as the first scene will be described as an example. 4 is performed under the control of the control circuit 112.
If there is an instruction to start review reproduction by the user, it is determined whether there is another instruction such as a stop instruction (S401). If there is another instruction as a result of this determination, the review reproduction process is terminated. On the other hand, if there is no other instruction, it is determined whether or not the last frame of the scene K has been reproduced and decoded from the recording medium 104 and stored in the memory 106 (S402). If the result of this determination is that decoding has not been completed up to the last frame, playback of the scene K is continued as it is, and processing returns to S401.

  On the other hand, as a result of the determination in S402, when the decoding is completed up to the last frame and stored in the memory 106, the reproduction circuit 107 uses the moving image data of the next scene (K + 1) as the second scene as the recording medium 104. Play from. Then, the decoding circuit 108 decodes the reproduced moving image data and stores it in the memory 106 (S403). Thereafter, the reproduction of the moving image data from the recording medium 104 is temporarily stopped. In this embodiment, when the first frame of the scene (K + 1) is decoded and stored in the memory 106, playback is paused.

  Next, the display circuit 109 determines whether or not the last frame (K-last) of the scene K has been displayed (S404). If the result of this determination is that it has not been displayed yet, the display of the scene K stored in the memory 106 is continued as it is. On the other hand, as shown in FIG. 11A, when the last frame (K-last) of the scene K is displayed, the display circuit 109 stores the first frame (K + 1-first) of the next scene (K + 1) in the memory. Read from 106. And it displays on the same screen as the last frame (K-last) of the scene K. At this time, as shown in FIG. 11B, for example, the frame (K-last) of the scene K is scrolled (wiped) to the left over a predetermined time, and the first frame (K + 1−) of the next scene (K + 1) is obtained. first) is displayed (S405).

  When scroll display is started in this way, the elapsed time from the start of display is measured, and it is determined whether or not a predetermined time has elapsed (S406). When the processing time elapses after the scroll display is started and the scroll display is finished, the display by the display circuit 109 is started from the first frame of the next scene K + 1. Further, the reproduction circuit 107 resumes the reproduction of the moving image data of the scene (K + 1) that has been paused from the recording medium 104 (S412), and returns to S401.

  If the scroll display has not ended, it is determined whether or not normal reproduction instruction information is input to the control circuit 112 from the operation switch 113 (S407). If the result of this determination is that there is a normal playback instruction, the display circuit 109 starts display from the first frame (K + 1-first) of the next scene (K + 1). Then, the reproduction circuit 107 resumes the reproduction of the moving image data of the scene (K + 1) that has been paused from the recording medium 104 (S412). The same process is repeated for the scene (K + 1). If there is no normal reproduction instruction, it is determined whether or not a repetitive reproduction instruction is input from the operation switch 113 to the control circuit 112 (S408). As a result of this determination, when there is an instruction for repeated playback, the playback circuit 107 returns to the first frame (K-first) of the scene K, and starts playback again from the first frame of the scene K (S413). Return to S401.

  If there is no repeated reproduction instruction, it is determined whether or not a reverse reproduction instruction has been issued (S409). If the result of this determination is that reverse playback has been instructed, the playback circuit 107 starts reverse playback from the last frame (K-last) of the scene K (S414). Then, the process proceeds to the reverse reproduction process (S416).

  On the other hand, if there is no reverse playback instruction, it is determined whether or not a reverse search instruction is given (S410). As a result of this determination, if there is an instruction for reverse search, reverse search reproduction is started from the last frame (K-last) of the scene K (S415), and the process proceeds to reverse reproduction processing (S416).

  If there is no reverse search reproduction instruction, it is determined whether there is another instruction (S411). If there is another instruction, the review reproduction process is terminated. If there is no other instruction, the process returns to S405.

Next, the reverse review reproduction process in S416 will be described.
FIG. 12 is a flowchart illustrating an example of the reverse review reproduction processing procedure of S416. The process of FIG. 12 is also executed under the control of the control circuit 112.
When the reverse review reproduction process is started, it is determined whether there is another instruction such as a stop instruction (S1201). If there is another instruction as a result of this determination, the reverse review reproduction process is terminated. On the other hand, if there is no other instruction, it is determined whether or not the first frame of the scene K is reversely reproduced from the recording medium 104 and decoded and stored in the memory 106 (S1202). If the result of this determination is that decoding has not been completed up to the first frame, reverse playback of the scene K is continued as it is, and the flow returns to step S1201.

  On the other hand, when the decoding is completed up to the first frame and stored in the memory 106, the reproduction circuit 107 reversely reproduces the moving image data of the previous scene (K-1) from the recording medium 104 as the second scene. . Then, the decoding circuit 108 decodes the reversely reproduced moving image data and stores it in the memory 106 (S1203). Thereafter, reverse playback of moving image data from the recording medium 104 is temporarily stopped. In this embodiment, when the data of the first frame of the previous scene K-1 is stored in the memory 106, the reproduction is paused.

  Next, it is determined whether or not the first frame of the scene K is displayed by the display circuit 109 (S1204). If the result of this determination is that it has not been displayed yet, the display of the scene K stored in the memory 106 is continued as it is. On the other hand, when the first frame of the scene K is displayed, the display circuit 109 reads the last frame of the previous scene (K-1) from the memory 106. Then, it is displayed on the same screen as the first frame of the scene K. At this time, similarly to S405, the first frame of the scene K is scrolled (wiped) to the left over a predetermined time to display the last frame of the previous scene (K-1) (S1205). When scroll display is started in this way, the elapsed time from the start of display is measured, and it is determined whether or not a predetermined time has elapsed (S1206). When the processing time elapses after the scroll display is started and the scroll display is finished, the display by the display circuit 109 is started from the last frame of the previous scene K-1. Further, the reproduction circuit 107 resumes the reverse reproduction of the moving image data of the scene K-1 that has been paused from the recording medium 104 (S1210).

  If the scroll display has not ended, it is determined whether or not a reverse reproduction instruction has been input from the operation switch 113 to the control circuit 112 (S1207). When there is an instruction for reverse playback, the display circuit 109 starts display from the last frame of the previous scene (K-1). Then, the reproduction circuit 107 resumes reverse reproduction of the moving image data of the scene (K-1) that has been paused from the recording medium 104 (S1210). In the case of the scene (K-1), the same process is repeated. If there is no reverse reproduction instruction, it is determined whether or not a normal reproduction instruction is input from the operation switch 113 to the control circuit 112 (S1208). When there is a normal playback instruction, the display circuit 109 starts display from the first frame of the current scene K and also starts playback of moving image data of the scene K from the recording medium 104 (S1211). Then, the process proceeds to the normal reproduction process of FIG. 4 (S1212).

  If there is no normal reproduction instruction, it is determined whether there is another instruction (S1209). If there is another instruction, the reverse review reproduction process is terminated. If there is no other instruction, the process returns to S1205.

  In this embodiment, an instruction is sent from the operation switch 113, but a command button may be displayed on the display screen of the display device 110 using a touch sensor.

  As described above, according to the present embodiment, when the scene K is played back, when the last frame of the scene K is displayed, the first frame of the next scene (K + 1) is displayed on the same screen. Thereby, the break of the scene becomes easy for the viewer to understand, and the viewer can easily find the desired scene. Furthermore, when the scene K and the scene (K + 1) are displayed, commands such as repeated playback, reverse playback, and reverse search are accepted for the scene K, so that the viewer can quickly reconfirm the desired scene. Can be done.

  Further, since the playback command shifts to the playback of the next scene, if the currently played scene is not the desired scene, the playback of the next scene can be started immediately.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described.
FIG. 2 is a block diagram illustrating a configuration example of the recording / reproducing apparatus 20 according to the present embodiment. The recording / reproducing apparatus 20 according to this embodiment includes two recording circuits and two reproducing circuits. The first recording circuit 103 and the first reproduction circuit 107 record and reproduce a moving image signal (moving image data) and other data on the first recording medium 104. The second recording circuit 201 and the second reproduction circuit 202 record and reproduce a moving image signal and other data on the second recording medium 203. Each of these two recording media 104 and 203 can be freely attached to and ejected from the recording / reproducing apparatus 20 by an unillustrated attachment / ejection mechanism.

  In the present embodiment, the user operates the operation switch 113 to select one of these two recording media 104 and 203 and record a moving image signal on the selected recording medium. Also at the time of reproduction, the moving image signal recorded on the selected recording medium is reproduced.

  In the present embodiment, an editing circuit 200 is further provided to edit the playlist file and management information. In addition, about the thing of the same structure as FIG. 1 demonstrated in 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. Here, the playlist is data indicating the playback order of moving image signals recorded on the recording media 104 and 203. The user can designate the reproduction order of the moving image signals recorded on the recording media 104 and 203 by operating the operation switch 113. The editing circuit 200 generates a playlist file for reproducing moving image signals in a designated order in accordance with an instruction from the user. The generated playlist file is recorded on the recording media 104 and 203. The control circuit 112 reproduces the playlist file recorded on the recording media 104 and 203, and when the reproduction of the playlist is instructed, the control circuit 112 reproduces the moving image signal in the order specified by the playlist file. The reproduction circuits 107 and 202 are controlled.

  FIG. 5 is a flowchart showing an example of a processing procedure in the review / playback mode in the recording / playback apparatus 20 according to the present embodiment. In addition, about the process which overlaps with FIG. 4, the same code | symbol as FIG. 4 is attached | subjected and description is abbreviate | omitted. Only different points will be described below. Here, it is assumed that the first recording medium 104 is selected and a moving image signal is reproduced from the first recording medium 104.

  When the scene K is reproduced and the last frame (K-last) is displayed, the first frame (K + 1-first) of the scene (K + 1) is further displayed as shown in FIG. The process proceeds to S406.

  If the scroll display has not ended in S406, it is determined whether or not the information input from the operation switch 113 is an editing instruction (S501). If it is not an editing instruction, the process proceeds to S408, and the same processing as in the first embodiment is performed. On the other hand, if it is an editing instruction, it is determined whether or not the editing instruction is an instruction to add to the playlist (S502). If the result of this determination is an instruction to add to the playlist, the editing circuit 200 reads the playlist file. Here, when the playlist file is recorded on the first recording medium 104, the first reproduction circuit 107 reads the playlist file into the memory 106 when the first recording medium 104 is loaded. If there is no playlist file on the first recording medium 104, the editing circuit 200 creates a new playlist file.

  Then, the editing circuit 200 adds the scene K to the playlist file and stores the playlist file in the memory 106 (S506). Then, the process returns to S406. Thereafter, the first recording circuit 103 records the playlist file stored in the memory 106 on the first recording medium 104.

  On the other hand, if it is not an instruction to add to the playlist, it is determined whether or not the editing instruction is a copy instruction (S503). If it is a copy instruction, copy processing is performed (S507).

FIG. 6 is a flowchart illustrating an example of a copy processing procedure in S507. Each process shown in FIG. 6 is performed under the control of the control circuit 112.
In S601 of FIG. 6, when the processing of S507 is started, the second reproduction circuit 202 is loaded with a second recording medium 203 as a copy destination recording medium, and data is transferred to the second recording medium 203. It is checked whether or not recording is possible (S602). If it is not in a recordable state, the display circuit 109 displays a warning that the second recording medium 203 is not loaded on the display device 110 to prompt the operator to load the recording medium.

  Next, the control circuit 112 determines whether or not an instruction to cancel copying is issued from the operation switch 113 (S615). If an instruction to cancel copying is given, the copying process is terminated as it is (S609). On the other hand, if an instruction to cancel copying has not been given, the second reproduction circuit 202 determines whether or not the second recording medium 203 is loaded (S616). If the second recording medium 203 is not loaded, the process returns to S614.

  On the other hand, when the second recording medium 203 is loaded, the second reproduction circuit 202 performs a mount process on the second recording medium 203 (S617). Then, the second reproducing circuit 202 determines whether or not the mounting process for the second recording medium 203 is successful (S618). If the mount process fails, the display circuit 109 displays an error display indicating that a mount error has occurred on the display device 110 (S619), and ends the copy process (S609). On the other hand, if the mounting process is successful, the process proceeds to S603.

  On the other hand, as a result of the determination in S602, if it is in a recordable state, the management information acquisition circuit 111 checks whether the management information recorded on the second recording medium 203 has already been acquired ( S603). As a result of this check, if the management information has already been acquired, the process proceeds to S604, and if the management information has not been acquired, the process proceeds to S610. Here, the management information for determining whether or not it is acquired corresponds to the management information A shown in the first embodiment.

  Then, the second reproduction circuit 202 checks whether or not management information is recorded on the second recording medium 203 (S610). If management information is recorded on the second recording medium 203, the management information is acquired from the second recording medium 203 and stored as management information A in the work area of the memory 106 (S611). Then, the process proceeds to S604. On the other hand, if the management information is not recorded on the second recording medium 203, the management information generation circuit 105 newly creates the management information A and stores it in the work area of the memory 106 (S612). Then, the process proceeds to S604.

  Next, it is checked whether or not the second recording medium 203 has a free area enough to record the scene K and its management information (S604). If there is no free area, the display circuit 109 displays a warning that there is no free area as an error on the display device 110 (S619), and ends the copy process (S609).

  On the other hand, when there is an empty area, when copying the scene K to the second recording medium 203, it is checked whether or not the same file name has already been recorded (S605). If the same file name does not exist and it is not necessary to change the file name, the process proceeds to S606.

  On the other hand, if the file name needs to be changed because the same file name already exists, the control circuit 112 searches for a file name that does not overlap with the file name recorded on the second recording medium 203. Then, the file name of the moving image data and management information is changed to the file name (S613), and the process proceeds to S606.

  Next, the first reproduction circuit 107 reads the moving image data of the scene K recorded on the first recording medium 104, and the second recording circuit 201 reads the moving image data of the scene K read to the second recording medium. It records in 203 (S606). When the moving image data of the scene K is thus copied, the process proceeds to S607.

  Next, the editing circuit 200 adds the management information of the scene K to the management information A developed in the memory 106. Further, the first reproduction circuit 107 reads the scene K management file (BK) from the first recording medium 104 and stores it in the memory 106 as scene K management information B (S607).

  Next, the second recording circuit 201 records the management information A to which the management information of the scene K is added as the management file A on the second recording medium 203. Further, the management information B of the read scene K is recorded on the second recording medium 203 as a management file (BK) (S608). Then, the copy process ends (S609).

  Returning to the description of FIG. 5, if the result of determination in S503 is that the editing instruction is not a copying instruction, it is determined whether or not the editing instruction is a deletion instruction (S504). If the instruction is to delete, the first recording circuit 103 deletes the moving image data of the scene K from the first recording medium 104. Further, the editing circuit 200 deletes the management information of the scene K from the management information A read to the memory 106. Further, the first recording circuit 103 deletes the management file (BK) of the scene K from the first recording medium 104 (S508). Then, the first recording circuit 103 updates and records the management information A from which the management information of the scene K is deleted as the management file A on the first recording medium 104, and ends the review reproduction process. When the review reproduction process is completed, the index display mode as shown in FIG. 10C is entered, and the scene (K + 1) can be reproduced if necessary.

  On the other hand, if the editing instruction is not a deletion instruction, it is determined whether or not the editing instruction is a division instruction (S505). If the edit instruction is a split instruction, the control circuit 112 shifts to the split edit mode for the scene K (S509), and ends the review reproduction process. Thereby, the operator can perform a division operation on the scene K in the division editing mode.

  As described above, according to the present embodiment, when the first frame of the next scene is displayed at the same time, editing such as addition to a playlist, copying of a scene to another medium, deletion of a scene, and division of a scene is performed. Added support for the current scene. Thus, the viewer can immediately edit the desired scene.
