In general, the components related to audio output are configured separately.

  The image / audio input unit 105 includes an image input unit configured by a digital camera including a lens, a CCD, and the like, and an audio input unit configured by a microphone or the like. Then, the image / sound input unit 105 generates moving image data, still image data, and sound data corresponding to the captured image and the recorded sound. The synchronization system 104 synchronizes the moving image data generated by the image / audio input unit 105 and the audio data.

  The memory 103 temporarily stores these data when processing the moving image data and the sound data generated by the image / sound input unit 105.

  The video codec 112, the audio codec 113, and the still image codec 114 perform encoding / decoding processing of moving image data, audio data, and still image data generated by the image / audio input unit 105, respectively.

  The demultiplexer 110 and the multiplexer 111 respectively separate and multiplex the encoded AV data (moving image data and audio data).

  The recording / reading unit 107 reads / writes information from / to the disk 106 that is a randomly accessible recording medium. The disk 106 is, for example, a magnetic disk such as a flexible disk / hard disk or an optical disk such as MO / MD / DVD / CD-R. Instead of the disk 106, a card such as an IC card / optical card can be used.

  The system controller 108 performs processing such as moving image shooting and still image shooting, for example, by controlling the entire recording / reproducing apparatus 100. In FIG. 1, only the moving image shooting processing unit 31 and the still image shooting processing unit 32 are illustrated as the configuration of the system controller 108, but the characteristic configuration of the system controller 108 is based on FIG. 5 described later. Will be described in detail.

  The operation unit 109 includes various buttons such as a moving image shooting button and a still image shooting button, and a user interface such as a switch. Therefore, the user of the recording / reproducing apparatus 100 operates various operations and processes of the recording / reproducing apparatus 100 by operating the operation unit 109.

  Note that various data and signals in the recording / reproducing apparatus 100, exchange of commands between the respective units, and the like are performed via the bus 115.

2. Recording Process Next, an image or audio recording process in the recording / reproducing apparatus 100 will be described.

2-1. Movie shooting process First, a movie shooting process for shooting and recording a movie will be described. In the present embodiment, “moving image shooting” means moving image shooting with recording of audio unless otherwise specified.

  The moving image shooting is started when the user of the recording / reproducing apparatus 100 presses the moving image shooting button of the operation unit 109 and instructs the recording / reproducing apparatus 100 to start moving image shooting. When moving image shooting is started, the moving image shooting processing unit 31 of the system controller 108 performs the following moving image shooting processing by operating each unit.

  First, the moving image shooting processing unit 31 starts the generation of the moving image data and the audio data by starting the operation of the image / audio input unit 105. Then, the moving image shooting processing unit 31 temporarily writes the generated moving image data and audio data in the memory 103.

  Then, the moving image shooting processing unit 31 transfers the moving image data and audio data written in the memory 103 to the video codec 112 and the audio codec 113, respectively. The video codec 112 and the audio codec 113 compress and code moving image data and audio data, respectively, and write them again in the memory 103. In the present embodiment, MPEG-2 is used as a compression encoding method for moving image data and audio data, but other compression encoding methods may be used.

  Then, the moving image shooting processing unit 31 transfers the compressed and encoded moving image data and audio data to the multiplexer 111. The multiplexer 111 generates AV data by AV multiplexing the moving image data and the audio data, and writes the AV data in the memory 103 again.

  Then, the moving image shooting processing unit 31 adds an error correction code to the AV data in an error correction circuit (not shown), and then records the AV data on the disk 106 via the recording / reading unit 107.

  In order to record the AV data on the disc 106, the moving image shooting processing unit 31 creates an AV file for storing the AV data on the disc 106 in advance.

  In addition, after the moving image shooting is completed and the recording of the AV data is completed, the moving image shooting processing unit 31 generates management information of the AV data and records it on the disc 106. The management information is information including AV file creation date and time, codec used, data size, recording position on the disc, total playback time length, playback time length in GOP units, data size, and the like. This management information may be added to the AV data as a header or footer, or the management information may be recorded as a separate file. In this embodiment, the management information is added to the AV data as a header. To do.

  The moving image shooting processing unit 31 generates representative still image data of the AV file after the moving image shooting is completed and the recording of the AV data is completed. The AV file representative still image data is data indicating a representative still image of the AV file. The representative still image of the AV file is a still image designated as representative of the AV file, and is a still image used when the file is displayed as a thumbnail. The generation of the representative still image data is performed by selecting a still image constituting one frame of the moving image data included in the AV data as the representative still image and appropriately performing data processing such as image reduction. Then, the moving image shooting processing unit 31 stores the generated representative still image data in the corresponding AV file.

  Also, one management file (hereinafter referred to as “index file”) for managing a plurality of files in the disk 106 is created and recorded on the disk 106. In the index file, a file name, a representative still image recording position, various attribute information, and the like related to each file in the disk 106 are registered (see FIG. 3 described later). Each time an AV file is recorded, the index file is updated by the moving image shooting processing unit 31 by adding new information corresponding to the AV file.

  In addition, when after-recording audio is recorded with respect to the already recorded AV file stream, an after-recording data file is created. Then, the management information regarding the after-recording data such as the file name of the after-recording data file, the codec used, and the reproduction time is added to the management information of the corresponding AV file. Note that “after-recording” is Japanese English based on “after recording”, and means that audio is recorded later on the previously recorded moving image.

2-2. Still Image Shooting Processing Next, still image shooting processing for capturing and recording still images will be described. Similarly, still image shooting is executed when the user of the recording / reproducing apparatus 100 presses the still image shooting button of the operation unit 109 and instructs the recording / reproducing apparatus 100 to perform still image shooting. When still image shooting is instructed, the still image shooting processing unit 32 of the system controller 108 performs the following still image shooting processing by operating each unit.

  First, the still image shooting processing unit 32 operates the image / sound input unit 105 to generate still image data. Then, the still image shooting processing unit 32 temporarily writes the generated still image data in the memory 103.

  Then, the still image shooting processing unit 32 transfers the still image data written in the memory 103 to the still image codec 114. The still image codec 114 compresses and encodes the still image data and writes it again into the memory 103. In this embodiment, the JPEG Exif method is used as the compression encoding method for still image data, but other compression encoding methods may be used.

  The still image shooting processing unit 32 adds an error correction code to the still image data after compression encoding in an error correction circuit (not shown), and then records it on the disk 106 via the recording / reading unit 107. .

  The still image shooting processing unit 32 creates a still image file for storing the still image data in the disk 106 in advance in order to record the still image data on the disk 106.

  Further, after the recording of the still image data is completed, the still image shooting processing unit 32 generates management information for the still image data and records it on the disk 106. The management information is information including the creation date / time of the still image file, the codec used, the data size, the recording position on the disc, and the like. This management information may be added to the still image data as a header or footer, or the management information may be recorded as a separate file. In this embodiment, the management information is added to the still image data as a header. Shall.

  The still image shooting processing unit 32 generates representative still image data of the still image file after the recording of the still image data is completed. The representative still image data of the still image file is data indicating a representative still image of the still image file. The representative still image of a still image file is a still image used when displaying a thumbnail of the file. The representative still image data is generated by appropriately performing data processing such as image reduction on the still image data. Then, the still image shooting processing unit 32 stores the generated representative still image data in the corresponding still image file.

  In addition, after the recording of the still image file is completed, the still image shooting processing unit 32 updates the index file recorded on the disk 106 by adding new information corresponding to the still image file.

2-3. Next, a still image shooting process during moving image shooting in which a still image is shot during moving image shooting will be described. In this case, as shown in FIG. 2, by starting moving image shooting, two still image shootings are performed during a period in which AV data is recorded in the AV file “VABC0001.mpg”, and each still image file “SABC0002” is recorded. A case where still image data is recorded in “.jpg” and “SABC0003.jpg” will be described.

  When the moving image shooting button is pressed, the moving image shooting processing unit 31 executes the moving image shooting process, and an AV file “VABC0001.mpg” is created on the disk 106 and AV data is recorded. At this time, a management information creation table for generating management information of AV data being recorded is created in the memory 103.

  Here, when the still image shooting button is pressed at the time t1 elapsed from the start of moving image shooting, the still image shooting processing unit 32 executes the above-described still image shooting processing, and the still image shooting processing unit 32 In addition to the moving image data obtained by moving image shooting, the audio input unit 105 generates still image data obtained by still image shooting with higher image quality, and the still image codec 114 compresses and encodes the still image data. Then, a still image file “SABC0002.jpg” is created on the disk 106, and the still image data after compression encoding is recorded.

  At this time, the AV file “VABC0001.mpg” and the still image file “SABC0002.jpg” are associated with each other. More specifically, the still image data of the still image file “SABC0002.jpg” is stored in a portion (specific portion) corresponding to the elapsed time t1 of the AV data recorded in the AV file “VABC0001.mpg”. Associated.

  Therefore, the management information recorded on the disc 106 together with the still image data in the still image file “SABC0002.jpg” includes the specific portion data indicating the specific portion and the file of the related file by the still image shooting processing unit 32. Related file name data indicating the name. The specific part data indicates the specific part by the elapsed time t1, and the related file name data indicates the file name “VABC0001.mpg” of the AV file being recorded.

  In the management information creation table in the memory 103, the moving image shooting processing unit 31 uses the file name of the related file for the AV file being recorded, that is, the related file name indicating the file name “SABC0002.jpg” of the still image file. Data and specific part data indicating the specific part are stored.

  Similarly, when the still image shooting button is pressed at the elapsed time t2 from the start of moving image shooting, a still image file “SABC0003.jpg” is created, specific partial data indicating the elapsed time t2, and the AV being recorded. Related file name data indicating the file name “VABC0001.mpg” of the file is included. The management information creation table in the memory 103 stores related file name data indicating the file name “SABC0003.jpg” of the still image file and specific partial data indicating the elapsed time t2.

  After that, when the moving image shooting button is pressed again to finish moving image shooting, the recording of AV data is stopped, and the table information stored in the management information creation table in the memory 103, that is, the still image shot during moving image shooting. The related file name data indicating the still image file name of the image and the specific partial data indicating the time when the still image was captured are recorded on the disc 106 as management information of the AV file “VABC0001.mpg”. Thereafter, the index file is updated based on the table information stored in the management information creation table in the memory 103.

  As shown in FIG. 3, the index file stores a table including an index, a file name, a representative still image recording position, attribute information, and the like. In FIG. 3, it is assumed that the still image file “SABC001.jpg” has already been recorded on the disk 106 before the creation of the AV file “VABC0001.mpg”, and there are four entries in the index file. Existing. Here, the representative still image recording position is a recording position on the disk 106 of the representative still image data of the file.

  In the present embodiment, presence / absence of a related file is included as one of the attribute information registered in the index file. The presence / absence of a related file is identification data indicating whether or not related file name data indicating a file name related to the file is included in the management information of each file. That is, “1” is recorded when the related file exists, and “0” is recorded when it does not exist. Therefore, the AV file “VABC0001.mpg” and the still image files “SABC0002.jpg” and “SABC0003.jpg” are related to each other. “1” is recorded, and the still image file “SABC0001.jpg” has no related file, so “0” is recorded in the presence / absence of the related file in the attribute information.

  In this way, by including identification data indicating the presence or absence of related files for each file in the index file, when performing a list display of each file, the index file is simply read to represent the representative still image of each file. It becomes possible to quickly display the presence or absence of related files.

  FIG. 4 shows the directory structure of the file system when each file is recorded as described above. An index file “AVIF0000.mov”, a still image folder “still”, and a movie folder “movie” exist on the disk 106, and still image files “SABC0001.jpg”, “SABC0002” exist in the still image folder. .jpg "and" SABC0003.jpg "are recorded. The movie folder further includes a group folder “100VABC”, and an AV file “VABC0001.mpg” is recorded in the group folder.

3. Details of System Controller Configuration Next, the configuration of the system controller 108 for performing the arbitrary association processing and playback processing described below will be described in more detail based on the block diagram of FIG. In FIG. 5, illustration of the moving image shooting processing unit 31, the still image shooting processing unit 32, the bus 115, and the like is omitted. In FIG. 5, the flow of information read from the disk 106 and the flow of information written to the disk 106 are illustrated by solid lines, and the flow of other signals is not illustrated or illustrated by broken lines.

  As shown in FIG. 5, the system controller 108 includes a control unit 108a and a storage unit 108b. Note that part or all of the information to be stored in the storage unit 108 b may be stored in the memory 103.

In FIG. 5, the flow of operation signals inside the control unit 108a is not shown.

  The recording / reading control unit 15 sends control signals from the management information changing unit 16, the management information acquiring unit 17, and the reproducing unit 18 to the recording / reading unit 107. This control signal is recorded / read when the management information change unit 16, the management information acquisition unit 17, and the playback unit 18 read data recorded on the disk 106 or write data to the disk 106. This is a signal for controlling operations such as access to a predetermined address of the disk 106 in the unit 107. In FIG. 5, the flow of the control signal inside the control unit 108a is also not shown.

  The reproduction unit 18 extracts data necessary for reproduction from the read signal input by the read signal input unit 13, temporarily stores it as reproduction data in the storage unit 108b, and appropriately reads the reproduction data from the storage unit 108b and reproduces it. By sending the signal to the signal output unit 12, the output unit 102 causes the output unit 102 to perform output based on the reproduction data, that is, display or audio output via the output control unit 101. Further, the reproducing unit 18 extracts information recorded in the index file from the read signal input by the read signal input unit 13, stores the information in the storage unit 108b as index information, and based on the index information, Acquire representative still image data of a file.

  The management information acquisition unit 17 extracts management information of a file to be reproduced from the read signal input by the read signal input unit 13, and stores it in the storage unit 108b as management information.

  The management information changing unit 16 rewrites the management information stored in the storage unit 108b according to the operation signal from the operation signal input unit 14, and records / reads the rewritten management information by the recording signal output unit 11. The corresponding management information recorded on the disk 106 is overwritten. That is, the management information changing unit 16 has a function of changing the management information recorded on the disk 106 in accordance with a user operation.

  The reproduction range designation unit 19 rewrites the reproduction range information stored in the storage unit 108b in accordance with the operation signal from the operation signal input unit 14. As will be described later, the playback range information is, for example, a range of a moving image to be extracted and played back when a part of a moving image associated with the still image is extracted and played simultaneously with the playback of the still image. This information is referred to by the playback unit 18 for determination.

  The mode switching unit 20 switches modes according to the operation signal from the operation signal input unit 14. The recording / playback apparatus 100 can switch between a playback mode with audio and a normal playback mode for still image playback, and can switch between a movie slide show mode and a normal slide show mode for a still image slide show. . Each mode will be described later, but the mode switching unit 20 switches between these modes. When switching the mode, the mode switching unit 20 instructs the playback unit 18 to switch the mode and rewrites the mode information stored in the storage unit 108b. The mode information is information indicating the currently set mode.

  The storage unit 108b stores the above-described index information, management information, reproduction data, reproduction range information, mode information, and the like. Here, with respect to management information and reproduction data, a plurality of types can be stored separately according to processing performed by each unit such as the management information changing unit 16, the management information acquiring unit 17, and the reproducing unit 18. It is like that.

  The above-described control unit 108a and each functional block thereof may be configured by hardware. However, by configuring the control unit 108a by a computer, and reading and executing a program (reproduction program) on the computer, the above-described each unit You may make it implement | achieve a functional block.

  The program can be supplied to the computer from a recording medium on which the program is recorded. The recording medium for recording the program may be configured to be separable from the computer, or may be incorporated in the computer. Even if this recording medium is mounted on a computer so that the recorded program code can be directly read by the computer, it can be read via a program reading device connected to the computer as an external storage device. It may be attached to.

  Examples of the recording medium include tape systems such as magnetic tape and cassette tape, disk systems including magnetic disks such as flexible disks / hard disks, and optical disks such as CD-ROM / MO / MD / DVD / CD-R, and IC cards. (Including memory card) / card system such as optical card, or semiconductor memory system such as mask ROM / EPROM (Erasable Programmable Read Only Memory) / EEPROM (Electrically Erasable Programmable Read Only Memory) / flash ROM .

  The recording / reproducing apparatus 100 may be configured to be connectable to a communication network, and the program code may be supplied via the communication network. The communication network is not particularly limited and can be selected as appropriate. Further, the transmission medium constituting this communication network is not particularly limited and can be selected as appropriate. Furthermore, the present invention can be realized in the form of a carrier wave or a data signal sequence in which the program code is embodied by electronic transmission.

4). Arbitrary Association Processing Next, arbitrary association processing in the recording / reproducing apparatus 100 will be described. The recording / reproducing apparatus 100 can arbitrarily associate an AV file and a still image file recorded separately. Thereby, the association according to the user's intention becomes possible. Specific processing contents will be described below.

  First, the playback unit 18 reads an index file and stores it as index information in the storage unit 108b. Further, the reproduction unit 18 recognizes the representative still image recording position of each still image file based on the read index information, reads the representative still image data corresponding to each still image file, and stores it as reproduction data in the storage unit 108b. Let Then, the playback unit 18 causes the output unit 102 to display a list display screen (thumbnail display screen) of representative still images via the output control unit 101 based on the read representative still image data.

  In this state, when the user selects a still image file to be associated by operating the operation unit 109, the management information acquisition unit 17 recognizes the selected still image file based on the selection operation, and manages the management information. Is stored as management information in the storage unit 108b.

  Next, the playback unit 18 and the management information acquisition unit 17 also display a list of representative still images, selection of the AV file by the user, and the selected AV file for the AV file in the same manner as the still image file selection process. Read management information.

  Next, the management information change part 16 will be in the state which receives the input of the designated time by a user. This designated time is for designating a time point at which still image data is associated with AV data, and is indicated by an elapsed time from the start of photographing in the AV data. In this state, when the user operates the operation unit 109 to input a designated time, the management information changing unit 16 uses the time indicated by the designated time signal as a still image file and an AV file stored in the storage unit 108b. Write as specific partial data in each management information.

  Further, the management information changing unit 16 writes the designated AV file name as related file name data to the management information of the still image file stored in the storage unit 108b. Similarly, the management information changing unit 16 writes the designated still image file name as related file name data in the AV file management information stored in the storage unit 108b.

  Further, the management information changing unit 16 rewrites the presence / absence (see FIG. 3) of the related files of the still image file and the AV file associated as described above to “1” in the index information stored in the control unit 108a. .

  Then, the management information changing unit 16 passes through the recording / reading unit 107 the related information of the still image file and the AV file in which the specific partial data and the related file name data are written, and the index information whose contents are rewritten. To overwrite the disk 106.

  If the user performs an end operation without inputting the specified time in a state where the input of the specified time by the user is received, the management information changing unit 16 specifies the specific part of the management information for each of the still image file and the AV file. As the data, “00: 00: 00: 00” indicating the shooting start time is written.

  Moreover, although the case where the user directly inputs the specified time has been described above, the present invention is not limited to this, and the specified time may be input as follows. That is, when the user performs an operation of designating the point when the user wants to associate the still image while the AV data is reproduced by the reproducing unit 18 and the user confirms the reproduced moving image, the management information changing unit 16 may calculate the elapsed time from the start of photographing at that time and write it as the specific partial data.

  Further, identification data (simultaneous recording identification data) indicating whether the related file is recorded at the same time or associated after being recorded separately is stored in the management information of each of the still image file and the AV file. It may be recorded. By doing so, for files associated later rather than simultaneously recording, related files can be easily searched when displaying a list, but moving images are not played instead of still images at the time of playback. Processing can be performed automatically.

  As described above, the recording / reproducing apparatus 100 as the recording apparatus according to the present invention manages information (related information) for associating still image data (second data) with a specific portion of AV data (first data). The management information changing unit 16 (related information generating unit) for generating the management information and the recording / reading unit 107 (recording unit) for recording the management information generated by the management information changing unit 16 on the disk 106 are provided. Thereby, the association between the AV data and the still image data can be realized.

  In addition, the recording / reproducing apparatus 100 includes an operation unit 109 that receives an input for associating still image data with a specific portion of AV data. Then, the management information changing unit 16 generates management information for AV data and still image data recorded in advance on the disc 106 based on the input received by the operation unit 109. Thereby, the AV data already recorded on the disc 106 and the still image data can be associated according to the user's intention.

  In the recording / reproducing apparatus 100, when the management information changing unit 16 generates the management information for the first data and the second data recorded in advance on the disc 106, the association is performed after the recording of each data. May be included in the management information. Thereby, when performing reproduction using the management information, it is possible to distinguish whether the data related to each other is related later or is recorded at the time of recording each data, The playback method and the like can be changed based on the distinction.

5. Reproduction process 5-1. Still Image Playback Processing Next, playback processing in the recording / playback apparatus 100 will be described. First, a reproduction process when reproducing one still image will be described.

  As shown in FIG. 6, in the recording / reproducing apparatus 100, the still image data of the still image file “SABC0002.jpg” is reproduced to display the still image, and the AV file “VABC0001. Part of audio data in the mpg AV data is extracted and played. The portion to be extracted is a portion corresponding to a predetermined time range including the time point t1 when the still image shooting is performed. Thereby, the sound near the time when the still image is shot can be played like BGM. Specific processing contents will be described below.

  First, the playback unit 18 reads an index file and stores it as index information in the storage unit 108b. Further, the reproduction unit 18 recognizes the representative still image recording position of each still image file based on the read index information, reads the representative still image data corresponding to each still image file, and stores it as reproduction data in the storage unit 108b. Let Then, the playback unit 18 causes the output unit 102 to display a list display screen (thumbnail display screen) of representative still images via the output control unit 101 based on the read representative still image data.

  At this time, for the still image file whose identification data of the presence / absence of the related file of the attribute information included in the index information (see FIG. 3) is “1”, there is an AV file associated with the representative still image. Or a button for reproducing related AV data may be displayed.

  With the representative still image list display screen displayed as described above, the flow of processing when a representative still image corresponding to a certain still image file is selected and a playback instruction is given by a user operation. This will be described based on the flowchart of FIG.

  First, the reproducing unit 18 determines the current mode based on the mode information stored in the storage unit 108b (S1). The mode to be identified here is a mode related to still image playback, and is a mode in which playback with audio for reproducing audio of AV data associated with the still image as well as playback of the still image is permitted (playback mode with audio). ) And a prohibited mode (normal playback mode). This mode is set in advance by the mode switching unit 20 based on a user operation and stored as mode information in the storage unit 108b.

  If it is determined in step S1 that the playback mode with sound is selected, the playback unit 18 reads the still image file of the selected still image, and stores the still image data recorded in the still image file in the storage unit 108b. While being stored as reproduction data, a still image is displayed on the output unit 102 via the output control unit 101 based on the stored still image data (S2).

  Also, the management information acquisition unit 17 acquires management information from the still image file of the selected still image, and stores it as management information in the storage unit 108b (S3). Then, the playback unit 18 determines whether there is an AV file related to the still image file of the selected still image based on the management information (S4). This determination can be made based on whether the management information includes related file name data. If there is no related AV file, the process proceeds to step S9.

  When there is a related AV file, the reproducing unit 18 reads out the related AV file based on the related file name data included in the management information. Then, based on the specific part data included in the management information, the playback unit 18 recognizes a part (specific part) associated with the still image in the AV data recorded in the AV file. Then, based on the reproduction range information stored in the storage unit 108b, the reproduction unit 18 stores the AV data portion (extraction portion) corresponding to the predetermined time range including the associated portion in the storage unit 108b. Store as playback data.

  AV data is data in which moving image data and audio data are multiplexed, but only audio data is stored as reproduction data here. Further, the AV data extraction part is stored separately from the still image data previously stored as reproduction data in the storage unit 108b.

  Here, the reproduction range information stored in the storage unit 108b is information for determining an extraction portion of AV data to be reproduced in relation to still image data, and includes, for example, a time point indicated by the specific partial data. Information specifying a time range. Specific examples of this designation are “5 seconds from the time corresponding to the specific portion”, “10 seconds from 3 seconds before the time corresponding to the specific portion”, and the like.

  Then, the playback unit 18 causes the output unit 102 to output audio via the output control unit 101 based on the AV data extraction portion stored in the storage unit 108b (S5). Thereby, the output unit 102 can output a sound associated with the still image, such as a sound recorded when the still image is captured, while displaying the still image.

  At this time, the mode switching unit 20 causes the output unit 102 to display a voice stop button via the output control unit 101 (S6). As shown in FIG. 8A, the voice stop button is a button displayed on a part of the screen displayed by the output unit 102. When this button is clicked by the operation of the operation unit 109 by the user, the mode is displayed. The switching unit 20 determines that the playback mode has been switched (S7), rewrites the mode information stored in the storage unit 108b to the normal playback mode, and stops playback of the audio data being played back. (S8), the process proceeds to step S12 to shift to the normal reproduction mode.

  If the audio stop button has not been clicked, the playback unit 18 determines whether or not the end of playback has been instructed by the user's operation of the operation unit 109 (S9). Repeat the process. Thus, the audio output based on the AV data extraction part is repeated until the audio stop button is clicked or the reproduction end instruction is given (repeat reproduction).

  On the other hand, when it is determined in step S1 that the playback mode is not the playback mode with sound but the normal playback mode, the playback unit 18 first reads out the still image file of the selected still image as in step S2, and Still image data recorded in the still image file is stored as reproduction data in the storage unit 108b, and a still image is displayed on the output unit 102 via the output control unit 101 based on the stored still image data (S10). ).

  Also, the management information acquisition unit 17 acquires management information from the still image file of the selected still image, and stores it as management information in the storage unit 108b (S11). Then, the playback unit 18 determines whether there is an AV file related to the still image file of the selected still image based on the management information (S12). If there is no related AV file, the process proceeds to step S15.

  If there is an associated AV file, the mode switching unit 20 causes the output unit 102 to display an audio playback button via the output control unit 101. As shown in FIG. 8B, the audio playback button is a button displayed on a part of the screen displayed by the output unit 102. When this button is clicked by the operation of the operation unit 109 by the user, the mode is displayed. The switching unit 20 determines that the playback mode has been switched (S14), rewrites the mode information stored in the storage unit 108b to the playback mode with sound, and moves to the playback mode with sound in step S5. Migrate to

  If the audio playback button has not been clicked, the playback unit 18 determines whether or not the end of playback has been instructed by the user's operation of the operation unit 109 (S15). Repeat the process.

  Here, based on the reproduction range information stored in the storage unit 108b, “5 seconds from the time corresponding to the specific portion”, “10 seconds from 3 seconds before the time corresponding to the specific portion”, etc. Although the data extraction portion has been defined, the reproduction range information can be changed by the user operating the operation unit 109 and the reproduction range designation unit 19 rewriting the content of the reproduction range information based on the operation. .

  Further, instead of based on the predetermined reproduction range information, the reproduction range designation unit 19 detects a change in the audio level based on the audio data before and after the specific portion, and determines the range of the extraction portion based on the detection result. May be. For example, a portion having a relatively high audio level in the vicinity of a specific portion may be cut out and the range may be used as the extraction portion.

  In addition, here, the extraction portion is described as being repeatedly reproduced. However, the extraction is not necessarily repeated, and may be performed only once.

  Further, here, it has been described that the playback unit 18 plays back the audio data of the AV file associated with the still image along with the playback of the still image. However, instead of playing back the audio data or playing back the audio data In addition, the reproduction unit 18 may reproduce the moving image data. In this case, on the screen displayed on the output unit 102, an area for displaying a still image and an area for displaying a moving image may be displayed separately. Further, the playback unit 18 may switch playback of a still image to playback of a related moving image in accordance with a user operation.

  In addition, when there is an AV file associated with the still image file to be reproduced and there is an after-record data file corresponding to the AV file, the after-record data file is replaced with the main audio data included in the AV file. The included post-record data may be reproduced. In this case, instead of reproducing the audio data of the AV file in step S5, the after-recording data of the after-recording data file is reproduced. For that purpose, the file name of the after-recording data file is recorded as the related file name in the management information of the still image file, and whether the main audio data or the after-recording data is reproduced in the management information. Alternatively, identification data indicating whether to perform mix reproduction may be included. Then, it is only necessary to select data to be reproduced according to the identification data during reproduction.

  As described above, the recording / reproducing apparatus 100 as the reproducing apparatus according to the present invention includes AV data (first data) and still image data (first data) associated with a predetermined shooting time point (specific part) of the AV data. 2 data) and a disc 106 as an information recording medium in which management information (related information) indicating a specific part of AV data associated with still image data is recorded.

  The recording / reproducing apparatus 100 reproduces the management information acquisition unit 17 (related information acquisition unit) that acquires the management information recorded on the disc 106, the still image data recorded on the disc 106, and the management information acquisition unit. A playback unit 18 (playback means) is provided for playing back the extracted portion extracted from the AV data recorded on the disc 106 based on the management information acquired in 17.

  Therefore, the recording / reproducing apparatus 100 can also reproduce a part of AV data associated with the still image data by reproducing the still image data. As described above, the recording / playback apparatus 100 can play back information by effectively utilizing the association between AV data and still image data.

  Here, the playback unit 18 plays back the audio based on the AV data extraction portion while playing back the still image based on the still image data. Accordingly, it is possible to output a sound related to the still image while displaying the still image. When the still image data is taken during recording of audio data, it is possible to output the sound near the time when the still image was taken, along with the still image display. Therefore, it is possible to obtain an effect of enhancing the sense of presence in reproducing a still image. Alternatively, the audio data may be recorded after recording a still image. In this case, along with the reproduction of the still image, it is possible to output sound according to the user's intention such as acoustic effects and BGM.

  In addition, the playback unit 18 plays back a moving image based on an AV data extraction portion while playing back a still image based on still image data. Thereby, it is possible to reproduce a moving image related to the still image while displaying the still image. When the still image data is taken during shooting of moving image data, the moving image near the time when the still image was shot can be reproduced together with the still image display. Therefore, in the reproduction of a still image, it is possible to present the state before and after the still image was taken.

  Note that the playback unit 18 may play back audio and moving images based on the AV data extraction portion while playing back still images based on still image data.

  In addition, the recording / reproducing apparatus 100 further allows the reproducing unit 18 to reproduce the AV data extraction portion that is performed together with the reproduction of the still image data (reproduction mode with sound) and prohibit mode (normal reproduction mode). May be provided with a mode switching unit 20 (switching means). The mode switching unit 20 performs the switching according to a user operation. As a result, when reproducing the still image data, whether to reproduce the extracted portion of the AV data can be determined according to the user's intention.

5-2. Next, a playback process when a slide show of still images is performed in the recording / playback apparatus 100 will be described. The recording / reproducing apparatus 100 has two modes for a slide show in which a plurality of still images are switched and reproduced at predetermined time intervals. One of them is a mode (movie slide show mode) for reproducing the extracted portion of the associated AV data instead of still image reproduction for a plurality of still images having an associated AV file. The other one is a mode for reproducing a still image as usual (normal slide show mode).

  9 and 10 show the concept of playback in the normal slide show mode and the concept of playback in the movie slide show mode, respectively. Here, the still image files “SABC0001.jpg”, “SABC0002.jpg”, “SABC0003.jpg”, “SABC0004.jpg”, and “SABC0005.jpg” included in the predetermined folder are played back in this order, Each still image is displayed for a preset Δts seconds. The still image files “SABC0001.jpg” and “SABC0002.jpg” are associated with the AV file “VABC0001.mpg”, and the still image files “SABC0004.jpg” and “SABC0005.jpg” It is assumed that the AV file is not associated with the still image file “SABC0003.jpg”.

  In this case, in the normal slide show mode, each still image is sequentially played back, whereas in the movie slide show mode, for the still image associated with the AV file, instead of playing the still image, the associated AV file is reproduced. From AV data, an extraction portion corresponding to a time width Δts seconds is reproduced with a specific portion (portion corresponding to t1, t2, t3, t4) as a center.

  The movie slide show mode will be described more specifically. Instead of playing the still image file “SABC0001.jpg”, AV data near the elapsed time t1 of the associated movie file “VABC0001.mpg” is played for Δts seconds, Instead of playing the still image file “SABC0002.jpg”, AV data near the elapsed time t2 of the associated moving image file “VABC0001.mpg” is played for Δts seconds. For the still image file “SABC0003.jpg”, since there is no associated AV file, the still image data included in the still image file “SABC0003.jpg” is reproduced for Δts seconds. Also, instead of playing the still image file “SABC0004.jpg”, this time, AV data near the elapsed time t3 of the moving image file “VABC0002.mpg” is played for Δts seconds, and the still image file “SABC0005.jpg” is played. Instead, the vicinity of the elapsed time t4 of the moving image file “VABC0002.mpg” is reproduced for Δts seconds.

  This makes it possible to reproduce a moving image as if it were a digest version of the moving image, which can be effectively used when it is desired to check the content of the moving image in a short period of time, or when it is desired to reproduce the moving image by extracting only the still image shooting points. Specific processing contents will be described below.

  First, the playback unit 18 reads an index file and stores it as index information in the storage unit 108b. Then, based on the read index information, the playback unit 18 reads still image data of each still image file included in a folder to be a slide show, and stores it as playback data in the storage unit 108b. Then, a slide show is executed in accordance with the flowchart shown in FIG.

  First, the playback unit 18 determines whether or not the current mode is the movie slide show mode based on the mode information stored in the storage unit 108b (S21). In the mode information of the storage unit 108b, a distinction between the normal slide show mode and the movie slide show mode is stored as the current mode, and this distinction is switched by the mode switching unit 20 according to the operation of the operation unit 109 by the user. Can do.

  In the movie slide show mode, the management information acquisition unit 17 acquires management information from the still image file to be played back and stores it as management information in the storage unit 108b (S22). Then, the playback unit 18 determines whether there is an AV file related to the still image file of the selected still image based on the management information (S23). This determination can be made based on whether the management information includes related file name data. If there is no related AV file, the process proceeds to step S27.

  When there is a related AV file, the reproducing unit 18 reads out the related AV file based on the related file name data included in the management information. Then, based on the specific part data included in the management information, the playback unit 18 recognizes a part (specific part) associated with the still image in the AV data recorded in the AV file. Then, based on the playback range information stored in the storage unit 108b, the playback unit 18 stores the AV data portion (extracted portion) corresponding to Δts seconds centered on the associated portion, as the storage unit 108b. Is stored as reproduction data.

  Then, the reproducing unit 18 reproduces the extracted portion of the AV data stored in the storage unit 108b, and causes the output unit 102 to output moving images and audio via the output control unit 101 (S24). Thereby, it can replace with the still picture used as reproduction object, and can output the animation and sound linked | related with the still picture.

  When the reproduction of the extracted portion is completed, the reproducing unit 18 determines whether there is a still image to be reproduced next (S25), and if there is, changes the reproduction target to the next still image (S26). The process from step S21 is repeated.

  If it is determined in step S21 that it is not the movie slide show mode, or if it is determined in step S23 that there is no associated AV file, the still image to be played is played back for Δts seconds (S27, S28). ), The process proceeds to step S25.

  In the above processing, since it is necessary to read the associated AV file while performing a slide show, it is desirable that the disk 106 be randomly accessible.

  Here, the playback time of the moving image and sound (time width of the extraction portion) and the playback time of the still image are fixed to Δts seconds, but the playback time may be determined for each still image to be played back. As for the video, as described above, the playback time may be determined based on the audio level, or the scene change is detected by examining the motion vector of the video data, and from the vicinity of the specific part to the scene change. This section may be reproduced.

  In addition, as shown in FIG. 12, during playback of a moving image or a still image, the playback range designating unit 19 displays a playback time bar indicating a range that can be set as the playback time on the screen, and the inside of the playback time bar. When the playback time length change controller is displayed and the user operates the operation unit 109 to move the playback time length change controller to the left or right, the playback range specification unit 19 displays the playback time bar of the playback time length change controller. It is also possible to set a reproduction time corresponding to the position in the memory and store it as reproduction range information in the storage unit 108b. As a result, the playback time can be freely changed during playback. It should be noted that such a playback time setting can also be applied to the above-described audio playback time setting when audio playback is performed along with still image playback.

  In addition, here, the explanation is made on the assumption that a moving image is reproduced instead of the reproduction of the still image. It may be. Further, instead of playing a moving image instead of playing a still image, only the audio data of the AV file associated with the still image being played back may be played simultaneously while performing a slide show with the still image.

  Also, here, the description has been made assuming that still image files included in a predetermined folder are targets of a slide show, but still image files to be target of a slide show are determined in advance and registered as playlist files. Also good. In the management information of the playlist file, the playback time of the moving image and the type of sound to be played back (whether to play back main sound data or after-record data) may be specified.

  Further, as shown in FIG. 13, the simultaneous recording identification data included in the management information of the still image file, that is, whether the related file is recorded at the same time or is recorded separately and associated later. Whether or not to reproduce AV data instead of still image data may be determined based on the identification data shown. For example, when the still image file whose simultaneous recording identification data is “0”, that is, the related file is a file associated later, the AV data is not reproduced instead of the still image data. The image data may be reproduced. Alternatively, AV data may be reproduced after still image data is displayed for several seconds. Accordingly, when a still image associated later is often a symbolic image explaining a related moving image, priority can be given to still image display. FIG. 13 shows a case where the still image file “SABC0005.jpg” is associated later. In this case, the still image is “SABC0005.jpg” in the time zone for reproducing the still image file “SABC0005.jpg”. Is displayed.

  As described above, the recording / reproducing apparatus 100 as the reproducing apparatus according to the present invention includes AV data (first data) and still image data (first data) associated with a predetermined shooting time point (specific part) of the AV data. 2 data) and a disc 106 as an information recording medium in which management information (related information) indicating a specific part of AV data associated with still image data is recorded.

  The recording / reproducing apparatus 100 includes a management information acquisition unit 17 (related information acquisition unit) that acquires management information recorded on the disc 106, reproduction of still image data recorded on the disc 106, and reproduction of still image data. Instead of the above, based on the management information acquired by the management information acquisition unit 17, a playback unit 18 (playback means) that can switch and execute playback of the extracted portion extracted from the AV data recorded on the disc 106 is provided. Yes.

  Therefore, the recording / reproducing apparatus 100 can switch between reproducing still image data and reproducing a part of AV data associated with the still image data. As described above, the recording / playback apparatus 100 can play back information by effectively utilizing the association between AV data and still image data.
