(First embodiment)
FIG. 1 is a block diagram showing a configuration of a recording apparatus 100 as an embodiment of the present invention. Note that the video camera 100 records a moving image in accordance with the AVCHD format.

  In FIG. 1, an imaging unit 101 captures a subject, generates and outputs a moving image signal indicating the subject. The imaging unit 101 includes an optical system such as a zoom lens and a focus lens, an image sensor such as a CCD, an iris, an AD converter that converts a captured moving image signal into a digital signal, a processing circuit that performs necessary processing on the captured moving image, and the like. including. The memory 102 stores moving image data output from the imaging unit 101 and other data.

  At the time of recording, the signal processing unit 103 performs encoding processing according to a known encoding method such as MPEG on the captured moving image data, and compresses the information amount. Further, at the time of reproduction, the signal processing unit 103 decodes the reproduced moving image data to expand the information amount. The display control unit 104 displays various types of information such as moving images and menu screens on the display unit 105 in accordance with instructions from the control unit 106. The display unit 105 includes a known display device such as a liquid crystal panel.

  The control unit 106 includes a microprocessor (CPU) and other necessary memory, and controls the operation of each unit of the recording apparatus 100 according to an instruction from the operation unit 108 in accordance with a program stored in the memory 102. The operation unit 107 includes various switches such as a power switch, a trigger switch for instructing start and stop of moving image shooting, a zoom switch, a playback switch, and a menu switch. The control unit 106 receives a user instruction from the operation unit 107. In this embodiment, the user operates a menu switch to display a menu screen on the display unit 105, and uses this menu screen to instruct setting of the relay recording mode.

  The recording / reproducing unit 108 records the moving image data, its additional information, and various other information on the recording medium A110 in accordance with an instruction from the control unit 106, and reproduces it from the recording medium A110. The recording / playback unit 109 records moving image data, its additional information, and various other information on the recording medium MB111 in accordance with an instruction from the control unit 106, and plays back from the recording medium B111. The recording medium A110 and the recording medium B111 are randomly accessible recording media such as a memory card and a hard disk (HDD). In the present embodiment, it is assumed that the recording media A110 and B111 are memory cards each incorporating a flash memory.

  In addition, the recording media A110 and B111 are configured so that the user can easily mount and eject the recording medium 100 with respect to the recording apparatus 100 by an unillustrated mounting and ejection mechanism, respectively. It is also possible to mount one of the recording media A110 and B111 and eject the other. The internal bus 112 is used for transferring various data and commands between the units of the recording apparatus 100.

  Next, basic recording processing and reproduction processing by the recording apparatus 100 will be described.

  In the recording apparatus 100, a moving image can be recorded on either the recording medium A110 or the recording medium B111. The user operates the operation unit 107 when the recording apparatus 100 is in the recording pause state, and selects one of these two recording media as a recording destination recording medium. The control unit 106 stores information indicating the selected recording medium in an internal nonvolatile memory.

  When the power of the recording apparatus 100 is turned on by the operation unit 107, the control unit 106 controls each unit to display a moving image of the subject corresponding to the moving image signal obtained by the imaging unit 101 on the display unit 105, and to record a pause. It becomes a state. In this state, when a recording medium as a recording destination is set and an instruction to start shooting is given by the operation unit 107, the control unit 106 controls each unit and starts recording a moving image. When receiving an instruction from the control unit 106, the imaging unit 101 outputs moving image data and temporarily stores it in the memory 102 via the bus 112. The signal processing unit 103 encodes the moving image data stored in the memory 102 and stores it again in the memory 102. When the recording medium A110 is selected as the recording destination, the control unit 106 instructs the recording / reproducing unit 108 to read the moving image data from the memory 102 and record it in the recording medium A110. In addition, when the recording medium B111 is selected as the recording destination, the control unit 106 similarly instructs to read the moving image data from the memory 102 and record it in the recording medium B111.

  When recording is instructed by the operation unit 107 after the recording is started, the control unit 106 moves the moving image to the recording / reproducing unit corresponding to the recording medium selected as the recording destination among the recording / reproducing units 108 and 109. To stop recording. In this embodiment, the recording / playback units 108 and 109 manage the moving image data recorded on the recording medium A110 and the recording medium B111 as moving image files according to a predetermined file system. In this embodiment, as described later, various types of additional information are recorded on the recording medium A110 and the recording medium B111 together with the moving image file. Further, the user can select any one of a plurality of types of recording modes having different data rates of moving image data to be recorded. In this embodiment, for example, two types of recording modes are prepared: a normal image quality mode and a high image quality mode. In the high image quality mode, encoding is performed so that the target rate of the encoded moving image data is 24 megabits / second (Mbps), and in the normal image quality mode, encoding is performed so as to be 15 Mbps. The control unit 106 instructs the signal processing unit 103 to change the data rate of the moving image data according to the recording mode set by the user. The signal processing unit 103 adjusts the code amount of the moving image data according to the designated recording mode, and controls the data rate.

  Next, the reproduction process will be described.

  When the playback unit is instructed by the operation unit 108, the control unit 106 detects a recording medium selected as a recording destination from among the recording medium A110 and the recording medium B111. Then, the recording / reproducing units 108 and 109 are controlled so as to reproduce the head portion of the moving image data included in the moving image file recorded on the selected recording medium. Then, the head portion of the reproduced moving image data is decoded by the signal processing unit 103 and sent to the display control unit 104. The display control unit 104 reduces the size of the decoded top screen, generates a representative image, and displays the representative image on the display unit 105. The user operates the operation unit 107 to select a desired representative image to be reproduced from the representative images of each moving image file displayed on the display unit 105 and instruct to reproduce the image.

  When the reproduction is instructed, the control unit 106 controls the recording / reproducing units 108 and 109 corresponding to the selected recording medium so as to reproduce the moving image file corresponding to the selected representative image. The recording / reproducing units 108 and 109 reproduce the designated moving image file from the recording medium and store it in the memory 102. The signal processing unit 103 reads and decodes the moving image data from the memory 102 and stores it in the memory 102 again. The display control unit 104 reads the moving image data from the memory 102 and displays the reproduced moving image on the display unit 105. When there is an instruction to stop reproduction, the control unit 106 stops reproduction of the moving image file and displays the representative image on the display unit 105 again.

  Next, relay recording will be described.

  In this embodiment, during recording of a moving image on one of the two recording media, when there is no recordable free space (recording remaining amount) on the recording medium and recording becomes impossible, the recording destination is switched to the other recording medium. Has a relay recording function. According to this relay recording, for example, when the recording medium A runs out of free space during recording of a moving image on the recording medium A110, the recording destination is switched from the recording medium A110 to the recording medium B111. Then, the moving image recording is continued on the recording medium B111. As described above, according to relay recording, a moving image is recorded across two recording media between a recording start instruction and a recording stop instruction.

  In the present embodiment, a plurality of additional information is recorded together with the moving image. FIG. 4 is a diagram showing relay recording information as the first additional information. The relay recording information is information for identifying that moving image data is recorded across two recording media. As shown in FIG. 4, the relay record information 401 has three states. When the value of the relay recording information 401 is 0 × 30 (first value), it indicates that the moving image is not recorded by relay recording. When the value of the relay recording information 401 is 0 × 031 (second value), it indicates moving image data recorded by relay recording and indicates the first half scene. When the value of the relay recording information 401 is 0 × 032 (third value), it indicates moving image data recorded by relay recording and indicates a second half scene.

  FIG. 5 is a diagram showing additional information. As shown in FIG. 5A, the additional information 501 includes a plurality of items. The second additional information 501 includes information on a file number, a recording mode, a device ID that is identification information of the recording device, a recording unit for moving image data, and recording start and end time codes of moving image data stored in the moving image file. Including. The file number is information on a file number added to each moving image file. The recording mode is information regarding the data rate of the recorded moving image data. The recording date indicates the date when the recording of the moving image starts. The start time code and the end time code respectively indicate the time code of the first frame and the last frame of the moving image data stored in the moving image file. In this embodiment, time code information indicating an elapsed time (frame) from the start of recording is generated and recorded for each frame of the recorded moving image data. When the user instructs to start recording, the time code value is set to 00:00:00 (hour: minute: second: frame). In this embodiment, since the frame rate of the moving image to be recorded is 30 frames / second, the value of the frame in the time code is 0-29.

  The control unit 106 generates the relay recording information 401 and the additional information 501 and stores them in the memory 102. Then, the control unit 106 controls the recording / reproducing unit to record the relay recording information 401 and the additional information 501 in association with the moving image file. In the present embodiment, the relay recording information 401 and the second additional information 501 are stored and recorded in the moving image file. However, the additional information may be recorded as a file different from the moving image file.

  FIG. 2 is a flowchart showing processing at the time of relay recording. The process of FIG. 2 is executed by the control unit 106 controlling each unit. In the present embodiment, relay recording is performed when it is detected that the two recording media A110 and B111 are both mounted, and relay recording is performed when only one of the recording media is mounted. Absent. In addition, after switching from one recording medium to the other, the recording of the moving image is continued, and then the recording is stopped when the recording capacity of the other recording medium is exhausted. In addition, when both recording media are mounted, the user may be configured not to perform relay recording.

  When the user gives an instruction to start recording in the recording pause state, the processing in FIG. 2 is started. First, the control unit 106 designates a recording medium selected as a recording destination by the user among the two recording media as a recording strategy (S201). Then, the control unit 106 instructs the recording / reproducing unit 108 or 109 corresponding to the recording medium designated as the recording destination to start recording a moving image. The recording / reproducing unit 108 or 109 records the moving image data on the recording medium as described above (S202). After the start of recording, when the recording is instructed by the user (S203), the control unit 106 instructs the recording / reproducing unit 108 or 109 that is recording the moving image to stop recording the moving image. The recording / reproducing unit 108 or 109 stops recording the moving image data (S204), and records the relay recording information 401 and the additional information 501 corresponding to the moving image (S205). When recording is completed, the recording pause state is established.

  On the other hand, when there is no instruction to stop recording in S203, the control unit 106 detects the remaining recording capacity of the recording medium being recorded (S206). The recording / reproducing unit 108 or 109 repeatedly detects the remaining recording capacity of the recording medium during moving image recording, and sends information on the remaining recording capacity to the control unit 106. If the remaining recording capacity remains, recording of the moving image is continued as it is. If it is determined that the remaining recording capacity is low, the control unit 106 determines whether the other recording medium other than the recording medium on which the moving image is recorded is loaded (S207). When the other recording medium is not loaded, the remaining recording capacity is exhausted, so the control unit 106 instructs the recording / reproducing unit 108 or 109 that is recording a moving image. The recording / reproducing unit 108 or 109 stops recording the moving image data (S204), and records the relay recording information 401 and the additional information 501 corresponding to the moving image (S205).

  If the other recording medium is loaded, the control unit 106 instructs the recording / reproducing unit 108 or 109 to stop recording on the recording medium that is recording the moving image. The recording / reproducing unit 108 or 109 stops recording the moving image data (S208), and records the relay recording information 401 and the additional information 501 corresponding to the moving image (S209). Next, the control unit 106 changes the recording destination to the other recording medium and instructs the recording / reproducing unit 108 or 109 corresponding to the recording medium of the recording destination to continue recording the moving image, and continues the recording. (S210).

  FIG. 3 is a diagram illustrating a moving image file recorded by the recording apparatus 100. FIG. 3A shows a moving image file recorded when relay recording is not performed. With the recording medium A110 selected, a moving image file 301 with a file name 00001 is recorded by a recording start / stop instruction. Thereafter, the recording destination is changed to the recording medium B111 by the user. In this state, a moving image file 302 having a file name of 00002 is recorded by a recording start / stop instruction.

  On the other hand, FIG. 3B shows a moving image file recorded when relay recording is performed. With the recording medium A110 selected, the moving image file 303 with the file name 00003 is recorded by a recording start instruction. If the recording medium A110 runs out during recording of the moving image file 303, the recording of the moving image file 303 is stopped, the recording destination is changed to the recording medium B111, and the moving image file 304 with the file name 00004 is stored in the recording medium B111. To be recorded. Thereafter, the recording of the moving image file 303 is stopped by an instruction to stop recording.

  As shown in FIG. 3A, the value of the relay recording information 401 recorded together with the moving image files 301 and 302 recorded when the relay recording is not performed is 0 × 30. When relay recording is performed as shown in FIG. 3B, the value of the relay recording information 401 of the moving image file 303 is 0 × 31, and the value of the relay recording information 401 of the moving image file 304 is 0 × 32. .

  FIG. 6 is a diagram showing the frames recorded in the moving image files 303 and 304 and the time code of each frame when relay recording is performed as shown in FIG. When the recording medium A110 is selected and a recording start instruction is issued in 601, the time code value 00:00:00 is added to the first frame, and recording is started. Thereafter, when the recording medium A110 is changed to the recording medium B111 in 602, the time code value 0: 00: 10: 15 is added to the last frame of the moving image file 303 recorded on the recording medium A110. A time code value of 00: 00: 10: 16 is added to the first frame of the moving image file 304 recorded on the recording medium B111. Thus, at the time of relay recording, the time code value added to the last frame of the moving image file 303 and the first frame of the moving image file 304 is continuous. Therefore, when the value obtained by adding one frame from the time code of the last frame of one video file is set as the time code of the first frame of the other video file, these two video files are recorded continuously by relay recording. It can be seen that Thereafter, when there is a recording stop instruction in 603, recording of the moving image file 304 is stopped.

  FIG. 5B shows additional information of the moving image files 303 and 304 recorded by relay recording as shown in FIG. Here, it is assumed that the high image quality mode (data rate is 24 Mbps) is selected as the recording mode. As shown in FIG. 5B, the additional information 502 of the moving image file 303 stores 00: 00: 00: 00 as the start time code value and 00: 00: 10: 15 as the end time code value. Is done. On the other hand, in the additional information 503 of the moving image file 304, 00: 00: 10: 16 is stored as the start time code value, and 00: 0: 30 is stored as the end time code value.

  Next, an image processing apparatus that combines two moving image files recorded by relay recording will be described. FIG. 7 shows the configuration of the image processing apparatus 700 in this embodiment. The image processing apparatus 700 can be realized by a general personal computer (PC) or the like.

  In the image processing apparatus 700, the CPU 701 controls each unit in accordance with application software stored in the storage unit 703. The memory 702 functions as a software cache memory stored in the storage unit 703 and a work memory of the CPU 701. The storage unit 703 includes a large-capacity nonvolatile memory such as a hard disk (HDD) or a flash memory drive (SSD). The storage unit 703 stores software. The storage unit 703 stores a moving image file read from the recording media A110 and B111, a combined moving image file, and the like, as will be described later. A display unit 704 displays information such as a user operation screen. The operation unit 705 includes a keyboard, a mouse, and other switches that can be operated by the user. The recording medium interface (IF) 706 includes a mounting unit to which a recording medium can be mounted, reads a moving image file and various data from the mounted recording medium, and writes a moving image file and the like to the recording medium. The recording medium IF 706 includes two mounting portions to which the recording medium A 110 and the recording medium B 111 in FIG. 1 are mounted. Therefore, the recording medium A110 and the recording medium B111 can be simultaneously mounted on the image processing apparatus 700. A bus 707 transmits and receives data and the like between the units.

  FIG. 8 and FIG. 9 are flowcharts showing moving image file combining processing by the image processing apparatus 700. The processing of FIGS. 8 and 9 is executed by the CPU 701. When the combining process is started, first, the CPU 701 displays a screen for instructing the user to mount the two recording media on the recording medium IF 706 on the display unit 704 and waits for the two recording media to be mounted. (S801). When it is detected that two recording media, here recording medium A110 and recording medium B111, are installed in recording medium IF 706 (S802), CPU 701 continuously records the moving images recorded on the two recording media by relay recording. A file is detected (S803).

  FIG. 9 is a flowchart showing the detection process in S803. In FIG. 9, the CPU 701 reads out the relay recording information of all moving image files from the two recording media A110 and B111 using the recording medium IF 706 and stores them in the storage unit 703. Then, based on the value of the relay recording information, the moving image files of the first half scene are detected from the moving image files recorded on the two recording media, and the number N1 is detected (S902). Here, as described above, when the value of the relay recording information is 0 × 31, it indicates a moving image file of the first half scene. Next, the CPU 701 detects the moving image file of the second half scene from the moving image files recorded on the two recording media, and detects the number N2 (S903). Here, when the value of the relay recording information is 0 × 32, it indicates a moving image file of the latter half scene.

  Then, the CPU 701 determines whether the detected N1 and N2 are each greater than 0 (S904). That is, here, it is determined whether or not at least one moving image file of the first half scene and moving image file of the second half scene are recorded on the two recording media. As a result of the determination, if at least one of the moving image file of the first half scene and the moving image file of the second half scene is not recorded, the process is terminated.

When one or more of the first half-scene moving image file and the second half-scene moving image file are recorded, the CPU 701 first selects one of the detected first-half scene moving image files (S905). Then, based on the additional information of each moving image file, the moving image file of the latter half scene continuous to the selected moving image file of the first half scene is detected (S906). That is, the CPU 701 confirms whether or not the additional information satisfies the following conditions 1-4 based on the selected additional information 501 of the first half scene and the additional information 502 of the moving image files of all the second half scenes. To do.
Condition 1: Recording mode is the same Condition 2: Recording device is the same Condition 3: The recording date of the moving image file of the first half scene and the recording date of the moving image file of the second half scene is within one day Condition 4: The moving image file of the first half scene The value obtained by advancing the end time code value by one frame coincides with the start time code of the moving image file of the latter half scene. When the CPU 701 satisfies all of these conditions 1-4, the two moving image files are continuously recorded by relay recording. It is determined that As described above, when there is a moving image file continuously recorded by relay recording (S907), the CPU 701 stores information on the file name of the moving image file of the first half scene and the file name of the moving image file of the second half scene. (S908). On the other hand, if there is no continuous second half-scene moving image file, the process proceeds to S909.

  In step S909, the CPU 701 confirms whether there is a moving image file of the remaining first half scene, and ends the process if there is no moving image file of the remaining first half scene. If there is a moving image file of the remaining first half scene, the CPU 701 selects a moving image file of the next first half scene (S910), returns to S906, and continues the processing.

  Returning to the processing of FIG. 8, the CPU 701 determines whether there is a moving image file continuously recorded on the two recording media A110 and B111 by the relay recording as a result of the processing of S803 (S804). If there are continuously recorded moving image files, the CPU 701 instructs the recording medium IF 706 to read out the moving image file having the file name stored in S908 (S805). The recording medium IF 706 reads the moving image file designated by the CPU 701 from the recording media A 110 and B 111 and stores it in the storage unit 703. The CPU 701 combines the moving image file of the first half scene and the moving image file of the second half scene stored in the storage unit 703, generates a combined moving image file, and stores the combined moving image file in the storage unit 703. At this time, the moving image file of the second half scene is combined after the moving image file of the first half scene. The moving image file combining process here may be simple combining at the binary level.

  On the other hand, as a result of the processing in S803, if there is no moving image file continuously recorded on the two recording media A110 and B111 by relay recording, the CPU 701 displays on the display unit 704 that a file that can be combined is not found (S807). ).

  As described above, in this embodiment, two moving image files continuously recorded across two recording media are detected and combined based on the additional information. Therefore, the user can obtain a moving image file in which a series of moving images divided and recorded on a plurality of recording media are combined into one with a simple configuration.

  In the present embodiment, the recording medium IF 706 includes two mounting portions, and the recording medium is mounted on these mounting portions. However, other configurations are possible. For example, the image processing apparatus 700 includes a known USB communication unit. A memory card reader or the like may be connected by USB, and the recording media A110 and B111 may be attached to the card reader. Alternatively, the recording apparatus 100 in FIG. 1 may be configured to include a USB communication unit. Then, the recording apparatus 100 and the image processing apparatus 700 are connected by USB in a state where the two recording media A110 and B111 are mounted on the recording apparatus 100, and the image processing apparatus 700 controls the recording apparatus 100, and FIG. The process 9 may be performed.

  In addition, the recording apparatus 100 and the image processing apparatus 700 are configured separately, but may be configured to include the other function in one. For example, the recording apparatus 100 may be configured to include the configuration of the image processing apparatus 700. Further, in addition to the time code, information whose value increases by a predetermined number for each frame, for example, information indicating the number of frames from the head, may be recorded as an item of the additional information 501. As condition 4, information on the number of frames may be used instead of the time code value.

  Next, a second embodiment will be described. Also in the second embodiment, the recording process of moving image files and additional information for the two recording media A110 and B111 is the same as that of the first embodiment. The configuration of the image processing apparatus 700 is the same as that of the first embodiment, but in the second embodiment, processing when a recording medium is attached to the recording medium IF 706 one by one and a moving image file is combined. Will be explained.

  FIG. 10 is a flowchart illustrating processing of the image processing apparatus 700 according to the second embodiment. When the combining process is started, first, the CPU 701 displays a screen for instructing the user to mount one recording medium on the recording medium IF 706 on the display unit 704, and waits for the recording medium to be mounted (S1001). ). When it is detected that the recording medium, here, the recording medium A110 is mounted on the recording medium IF 706 (S1002), the CPU 701 instructs the recording medium IF 706 to read the relay recording information of each moving image file. The recording medium IF 706 reads the relay recording information from the recording medium and stores it in the storage unit 703. The CPU 701 detects the moving image file recorded by the relay recording based on the read relay recording information (S1003), and instructs the recording medium IF 706 to read and store the detected moving image file. The recording medium IF 706 reads the moving image file designated by the CPU 701 from the recording medium and stores it in the storage unit 703 (S1004).

  Next, the CPU 701 displays a screen for inquiring whether there is another recording medium on which a moving image file is recorded by relay recording on the display unit 704. When the user instructs that there is another recording medium (S1005), the process returns to S1001, and a screen for instructing the user to mount one recording medium on the recording medium IF 706 is displayed on the display unit 704. .

  When the user instructs that there is no other recording medium (S1005), the processing shown in FIG. 9 is executed (S1006). Next, the CPU 701 determines whether there is a moving image file continuously recorded on the two recording media A110 and B111 by the relay recording as a result of the processing of S1006 (S1007). If there is a continuously recorded moving image file, the CPU 701 combines the moving image file of the first half scene and the moving image file of the second half scene detected in S906 from the moving image file stored in the storage unit 703. , Generate a combined video file. The moving image file combining process here may be simple combining at the binary level.

  On the other hand, as a result of the processing of S1007, when there is no moving image file continuously recorded on the two recording media A110 and B111 by relay recording, the CPU 701 displays on the display unit 704 that a file that can be combined is not found (S1009). ).

  Thus, also in the present embodiment, two moving image files continuously recorded across two recording media are detected and combined based on the additional information. Therefore, the user can obtain a moving image file in which a series of moving images divided and recorded on a plurality of recording media are combined into one with a simple configuration.

  Next, a third embodiment will be described. In the first embodiment, on the basis of the relay recording information, one recorded by relay recording is detected from the moving image file recorded on the recording medium, and further, the continuously recorded moving image file is detected. In this embodiment, when one moving image file is recorded on each of the two attached recording media, the value of the relay recording information is not checked, and the two moving image files are checked based on the additional information. Check continuity.

  FIG. 11 is a flowchart showing the processing of the CPU 701 in the third embodiment. When the combining process is started, first, the CPU 701 displays a screen for instructing the user to mount the two recording media on the recording medium IF 706 on the display unit 704 and waits for the two recording media to be mounted. (S1101). When it is detected that two recording media, here recording medium A110 and recording medium B111, are installed in the recording medium IF 706 (S1102), the CPU 701 determines whether one moving image file is recorded on each of the two recording media. It is determined whether or not (S1103). If two or more moving image files are recorded on at least one of the recording media, the process proceeds to S803 and subsequent steps in FIG.

On the other hand, when one moving image file is recorded on each recording medium, the CPU 701 determines whether or not these two moving image files are continuously recorded by relay recording (S1104). Here, the CPU 701 determines whether the two moving image files satisfy the following condition 5-8 based on the additional information 501 of each moving image file.
Condition 5: Same recording mode 6: Same recording device Condition 7: The difference between the recording date of one video file and the recording date of the other video file is within one day Condition 4: End time code of one video file The value advanced by one frame matches the start time code of the other moving image file. As a result, when two moving image files are recorded continuously by relay recording, the CPU 701 reads the recording medium IF 706. Instruct to read the moving image file from each recording medium. The recording medium IF 706 reads the moving image file designated by the CPU 701 from the recording media A 110 and B 111 and stores it in the storage unit 703. Then, the CPU 701 combines the moving image file of the latter half scene after the moving image file of the first half of the two moving image files stored in the storage unit 703, generates a combined moving image file, and stores the combined moving image file in the storage unit 703. By comparing the start time code and end time code of the additional information 501 of the two moving image files, it is possible to detect which of the two moving image files is the first half scene.

  Thus, also in the present embodiment, two moving image files continuously recorded across two recording media are detected and combined based on the additional information. Therefore, the user can obtain a moving image file in which a series of moving images divided and recorded on a plurality of recording media are combined into one with a simple configuration.
