  However, in Patent Document 1, newly captured moving image data is directly connected to moving image data of an existing moving image file. However, for example, if the battery is removed or the memory card is removed while performing linked shooting, an error occurs. In this case, the video data of the existing video file that was being connected may become unreadable. Or, video data that was being recorded may be automatically linked. For example, when a user tries to generate a moving image file in which a plurality of moving image data having a predetermined time length is collected, moving image data other than the predetermined time length is mixed into the moving image file due to an error. In this case, for example, when the video file is set to fast-forward and rewind (previous jump, backward jump) in units of a predetermined time length during playback, the desired operation cannot be performed and the operation becomes inconvenient. It will end up.

  In the present invention, when generating a moving image file in which a plurality of moving image data for a predetermined time is generated, the recording state of the moving image is set when a recording time different from the recording time of the moving image data recorded in the existing moving image file is set. It is an object of the present invention to provide a moving picture recording apparatus that can automatically change the setting so that the user's playback operation is not inconvenient.

  In order to achieve such an object, the recording apparatus of the present invention includes an acquisition unit that acquires moving image data, and a recording time of the moving image data that is recorded by a single recording instruction in a predetermined recording mode. A setting means for setting any one of the recording times; a recording means for recording the moving image data of the recording time set by the setting means on a recording medium in response to the recording instruction in the predetermined recording mode; The moving image data recorded in response to the recording instruction in a predetermined recording mode is added to a predetermined moving image file that is already recorded on the recording medium and includes the moving image data recorded in the predetermined recording mode. Control means for controlling whether the recording time set by the setting means is included in the predetermined moving image file. It is determined whether or not the recording time is the same as the first recording time that is the recording time by one recording instruction, and it is determined that the recording time set by the setting means is the same as the first recording time In this case, the recording unit is controlled to add the moving image data recorded in the predetermined recording mode and having the recording time set by the setting unit to the predetermined moving image file, so that the predetermined moving image file is , Each including a plurality of moving image data of the first recording time recorded by one recording instruction, and determining that the recording time set by the setting means is not the same as the first recording time In this case, the recording data recorded in the predetermined recording mode and having the recording time set by the setting unit is not added to the predetermined moving image file. And controlling means, the predetermined moving image file to be free of moving picture data recording time other than the video data of said first recording time.

  In the present invention, when generating a moving image file in which a plurality of moving image data for a predetermined time is generated, the recording state of the moving image is set when a recording time different from the recording time of the moving image data recorded in the existing moving image file is set. Can be automatically changed so that the user's playback operation is not inconvenient.

  Hereinafter, examples of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments.

  In this embodiment, an imaging apparatus capable of shooting a moving image will be described. In the normal moving image shooting mode (first mode), the image pickup apparatus of the present embodiment can record moving image data shot from the start to the end of one moving image shooting as a single file on a recording medium. it can. In the continuous movie shooting mode (second mode), a movie file in which newly recorded movie data (new movie data) is added to a movie file (existing movie file) already recorded on the recording medium. (Additional video file) can be recorded on a recording medium. That is, in the continuous moving image shooting mode, a new file is not recorded on the recording medium every time recording is performed because additional recording is performed on the existing moving image file. Incidentally, in the continuous moving image shooting mode, under a specific condition, it can be recorded on the recording medium as a new moving image file (new moving image file) without adding to the existing moving image file.

In particular, in the continuous moving image shooting mode, the image pickup apparatus according to the present embodiment can display a moving image on the display screen after shooting to allow the user to confirm the image. At this time, the moving image data (existing moving image data) of the existing moving image file and the new moving image data can be seamlessly reproduced and displayed. Then, the video that the user has played continuously is confirmed, and the displayed selection screen (also referred to as an operation screen or user interface)
It is possible to select and execute processing such as recording an additional recording moving image file, recording new moving image data as a separate file, and deleting new moving image data. Further, a physical switch for selecting these processes may be provided.

  At this time, if a plurality of moving image files cannot be reproduced in parallel, the above-described additional moving image file is recorded in advance on a recording medium, and the moving image data of the additional moving image file is sequentially reproduced and displayed. Then, the state of the moving image file is changed according to the selected process. In other words, when the additional video file is recorded, the additional video file is recorded on the recording medium.

  In addition, when recording new video data as a separate file without appending, the new video data is separated from the append video file and header information is added to form a new video file. New video file) on the recording medium. Then, in order to make the moving image file composed of the existing moving image data remaining in the additional recording moving image file into one moving image file, the header information of the additional recording moving image file is changed and recorded on the recording medium. That is, editing is performed to return to the state of the existing moving image file.

  In addition, when deleting new moving image data, the newly captured moving image data is separated from the additional recording moving image file, and the moving image data is deleted from the recording medium. Further, in order to make a moving image file composed of existing moving image data remaining in the additional recording moving image file into one moving image file, the header information of the additional recording moving image file is changed and recorded on the recording medium. That is, editing is performed to return to the state of the existing moving image file.

  In this embodiment, a recording medium having a format corresponding to a file system for recording using a file allocation table (in this embodiment, FAT32 or the like is taken as an example of the file system) is used. The file allocation table (FAT) is edited when the above-described additional video file is generated or when the additional video file is separated. Therefore, it is possible to easily add and separate moving images.

  According to the imaging apparatus of the present embodiment, even if the imaging apparatus does not seamlessly reproduce a plurality of files of moving image data, the existing moving image data and the new moving image data are seamlessly reproduced immediately after a new moving image is captured. Can be displayed. Then, according to the process selected by the user at this time, it is possible to record the additionally recorded moving image file, record the new moving image data as another file, or delete the new moving image data. Therefore, the imaging apparatus of the present embodiment can improve usability for the user while avoiding an increase in cost.

  Hereinafter, such an imaging apparatus will be described.

  In this embodiment, first, the overall configuration of the imaging apparatus will be described with reference to FIG. The file format of the moving image file recorded on the recording medium will be described with reference to FIG. The control operation of the imaging apparatus in the normal moving image shooting mode will be described with reference to FIG. A data area and a FAT area of the moving image file recorded on the recording medium will be described with reference to FIG. Further, the control operation of the imaging apparatus in the continuous moving image shooting mode will be described with reference to FIG. Further, with reference to FIG. 6, the addition of a moving image file on a recording medium in the continuous moving image shooting mode will be described. A confirmation screen after shooting in the continuous moving image shooting mode will be described with reference to FIG. Further, the separation of the moving image file on the recording medium will be described with reference to FIG. Further, with reference to FIG. 9, a partial deletion of a moving image file on a recording medium will be described. In addition, with reference to FIG. 10, the state of the additionally-recorded moving image file when the recording of the moving image is stopped during the recording of the new moving image data in the continuous moving image shooting mode and the recording state of the moving image file in the subsequent shooting will be described.

  First, the overall configuration of the imaging apparatus 100 of the present embodiment will be described with reference to FIG.

  In FIG. 1, the control unit 101 includes, for example, a CPU (MPU), a memory (DRAM, SRAM), and the like, and executes various processes (programs) in response to an operation signal from the operation unit 102 that receives an operation from a user. Thus, each block of the imaging apparatus 100 is controlled, and data transfer between the blocks is controlled. The control unit 101 may be a microcomputer including a CPU and a memory.

  The operation unit 102 includes switches for inputting various operations related to shooting such as a power button, a recording start button, a zoom adjustment button, and an autofocus button. Further, a menu display button, a determination button, other cursor keys, a pointing device, a touch panel, and the like are provided, and an operation signal is transmitted to the control unit 101 when these keys and buttons are operated by the user.

  The bus 103 is a general-purpose bus for sending various data, control signals, instruction signals, and the like to each block of the imaging apparatus 100.

  The imaging unit 110 controls the light amount of the optical image of the subject captured by the lens using an aperture, converts the optical image into an image signal using an imaging element such as a CCD sensor or a CMOS sensor, performs analog-digital conversion, and performs an image processing unit. 111.

  The image processing unit 111 executes processing necessary for image recording / playback, and is a microcomputer equipped with a program for executing the following processing. Further, the following processing may be executed as a partial function of the control unit 101. The image processing unit 111 temporarily stores a digital image signal acquired from the imaging unit 110 in a memory (not illustrated), and determines white balance, color, brightness, and the like from setting values set by the user and image characteristics. An image quality adjustment process for adjusting based on the set value is performed. In addition, processing for generating moving image data from image signals of a plurality of frames subjected to image quality adjustment processing is performed. Here, the image processing unit 111 according to the present embodiment may generate moving image data that is compression-coded by intra-frame encoding each frame of the moving image data. Moreover, you may produce | generate the moving image data compression-coded using the difference between several flame | frames of moving image data, a motion estimation, etc. For example, Motion JPEG, MPEG, H.264. H.264 (MPEG4-Part10 AVC) and other known compression and encoding video data can be generated. In general, intra-frame-coded frame image data is referred to as an I picture, and inter-frame encoded image data using a difference from the front frame is referred to as a P picture, and the difference between the front and rear frames is used. The inter-frame encoded image data is called a B picture. These compression methods use well-known methods and are not related to the features of the present invention, so the description is omitted.

  The moving image data processed by the image processing unit 111 is transmitted to the memory 104 by the control unit 101.

  Next, the voice input unit 120 collects (collects) sounds around the imaging device 100 using, for example, a built-in omnidirectional microphone or an external microphone connected via a voice input terminal. The acquired analog audio signal is converted into a digital signal and transmitted to the audio processing unit 121.

  The sound processing unit 121 executes a process necessary for recording and reproducing sound, and is a microcomputer equipped with a program for executing the following process. Further, the following processing may be executed as a partial function of the control unit 101. The audio processing unit 121 temporarily stores the digital audio signal transmitted from the audio input unit 120 in a memory (not shown), and performs processing such as level optimization processing and noise reduction processing. Moreover, the process which compresses an audio | voice signal is performed as needed. The audio data processed by the audio processing unit 121 is stored in the memory 104 by the control unit 101.

  The display control unit 131 is a microcomputer that performs display control for displaying an image on the display unit 130. The display control unit 131 reads a digital image signal temporarily stored in the image processing unit 111 and displays the digital image signal on the display unit 130. Let The display unit 130 may be, for example, a liquid crystal panel or an organic EL panel mounted on the imaging device 100, or a display device (for example, a television, a monitor, or a projector) different from the imaging device 100.

  The memory 104 temporarily stores moving image data, audio data, and the like obtained by the image processing unit 111 and the audio processing unit 121.

  Then, for example, the control unit 101 reads moving image data, audio data, and the like from the memory 104 and transfers them to the recording / reproducing unit 140, and the recording / reproducing unit 140 records the transferred moving image data, audio data on the recording medium 141. . The recording / playback unit 140 records the moving image data and the audio data on the recording medium 141 as one moving image file. At this time, the control unit 101 may generate various data indicating camera settings at the time of shooting, detection data, and the like, and may record the data together with the moving image data and audio data on the recording medium 141. Here, the recording medium 141 may be a recording medium built in the imaging apparatus or a removable recording medium. For example, the recording medium includes all types of recording media such as a hard disk, an optical disk, a magneto-optical disk, a CD-R, a DVD-R, a magnetic tape, a nonvolatile semiconductor memory, and a flash memory.

  The recording / playback unit 140 reads (plays back) a moving image file or the like recorded on the recording medium 141. Then, the control unit 101 reads, for example, header information of a moving image included in the read moving image file, and based on the header information, the recording / reproducing unit 140 reads the moving image data and audio data to be reproduced from the recording medium 141. Control. The recording / reproducing unit 140 transfers the read moving image data to the image processing unit 111 and the reproduced audio data to the audio processing unit 121. The image processing unit 111 sequentially stores one frame image of the reproduced moving image data in a memory (not shown). Then, the display control unit 131 sequentially reads out one frame image stored in a memory (not shown) and displays it on the display unit 130. On the other hand, the audio processing unit 121 decodes a digital audio signal from the reproduced audio data, converts it into an analog signal, and outputs the analog audio signal to an audio output unit (speaker, earphone terminal, audio output terminal, etc.) not shown. .

  As described above, the imaging apparatus 100 according to the present embodiment has the normal moving image shooting mode (first mode) and the continuous moving image shooting mode second mode. In the normal moving image shooting mode (first mode), moving image data shot from the start to the end of one moving image shooting is recorded on a recording medium as one file. Further, in the continuous moving image shooting mode (second mode), an additional recording moving image file in which new moving image data is added to an existing moving image file can be recorded on a recording medium.

  Here, the file format of the moving image file recorded on the recording medium 141 by the imaging apparatus 100 of the present embodiment will be described. In this embodiment, the MOV file format is used as the general-purpose format.

  As shown in FIG. 2A, the MOV file recorded in the MOV file format is composed of “mdat atom” of stream data of moving image data and “moov atom” of information related to stream data of moving image data. Has been.

  The “mdat atom” is further composed of a plurality of chunks (chunk cN) as shown in FIG. 2 (b), and each chunk is composed of a plurality of samples (samplesM) as shown in FIG. 2 (d). Is done. Each sample corresponds to each frame of the encoded moving image data of I0, B-2, B-1, P3,..., For example, as shown in FIG. . Here, I 0, I 1, I 2,..., In are frame image data (I picture) subjected to intra coding (intra-frame coding). B 0, B 1, B 2,..., Bn are frame image data (B picture) that is encoded (inter-frame encoding) with reference from both directions. P 0, P 1, P 2,..., Pn are frame image data (P picture) that is encoded (inter-frame encoded) with reference from one direction (forward direction). In the present embodiment, an example in which interframe coding is used has been described. However, frame image data (I picture) that is all intraframe coded may be used.

  As shown in FIG. 2C, the “moov atom” is a “trak” that stores information about the stream data of the moving image data stored in the “mvhd atom” and the “mdat atom” including header information in which the creation date and time is recorded. "Atom". That is, “moov atom” records management information of moving image data. As information stored in the “trak atom”, as shown in FIG. 2 (h), “stco atom (also referred to as stco box)” that stores information on the offset value for each chunk of the “mdat atom”, As shown in FIG. 2G, “stsc atom (also referred to as stsc box)” for storing information on the number of samples in each chunk, and for storing information on the size of each sample as shown in FIG. stsz atom (also called stsz box) ". Therefore, the amount of data stored in the “stco atom”, “stsc atom”, and “stsz atom” increases with the amount of recorded image data, that is, the recording time. For example, when an image of 30 frames per second is recorded as a MOV file so that it is stored in one chunk every 15 frames, the data becomes about 1 megabyte in 2 hours, and a moov atom having a capacity of 1 megabyte is required. Become. When recording in the MOV file format, the moving image stream data increases with time and its size is very large. Therefore, it is necessary to write out the moving image stream data as a file to the external memory 407 even during recording. However, as described above, since the size of the moov atom increases according to the recording time, the size of the MOV header is unknown until the recording is completed. Can not. Therefore, in general, by using the flexibility of the MOV file format, “mdat atom” is placed at the beginning of the file, and “moov atom” is placed after “mdat atom” at the end of recording. The above problem can be addressed.

  However, when playing back an MOV file, the “moov atom” of the MOV file is read from the recording medium, and the above “stco atom”, “stsc atom”, and “stsz atom” are analyzed from the “moov atom”. , Each chunk in the “mdat atom” can be accessed. Therefore, it is faster to access the “mdat atom” when the “moov atom” is arranged at the head of the “MOV file” as shown in FIG. 2 than when the “moov atom” is arranged behind the “mdat atom”. .

  Therefore, the imaging apparatus 100 according to the present exemplary embodiment can generate a moving image file in which “moov atom” is arranged at the head of the “MOV file” as illustrated in FIG. 2 by performing processing according to the procedure illustrated in FIG. I am doing so.

  In this embodiment, the file management system of the recording medium 141 will be described as using a FAT file system generally used in embedded devices. Since the technology of the FAT file system itself is widely known, only the characteristic operation of this embodiment will be described. Incidentally, for example, a flash memory of the recording medium 141 manages a physical memory area in the recording medium 141 by a built-in microcomputer. For the access from the recording / reproducing unit 140 of the imaging apparatus 100, it is shown that data is logically stored in the FAT file system.

<Normal movie shooting mode>
Here, the operation for generating a moving image file in which “moov atom” is arranged at the head of “MOV file” as shown in FIG. 2 will be described with reference to FIGS. FIG. 3 is a flowchart for explaining the operation of the imaging apparatus 100 when moving image shooting is performed in the normal moving image shooting mode (first mode) of the present embodiment. These operations are basically controlled by the control unit 101 of the imaging apparatus 100. FIG. 4 shows data written in each logical cluster of the recording medium 141 and FAT (file allocation table) when moving image shooting is performed in the normal moving image shooting mode (first mode) of the present embodiment. It shows the state.

  First, when a shooting start instruction is input from the operation unit 102 in a state where the normal moving image shooting mode is selected from the operation unit 102 of the imaging device 100, the control unit 101 sends a shooting start instruction to each of the imaging devices. Transmit to the block to start moving image shooting (Yes in S301).

  Then, the imaging unit 110 acquires a digital image signal, and the image processing unit 111 performs predetermined image processing on the digital image signal, and generates moving image data from a plurality of frames of image signals. Then, the control unit 101 temporarily stores the moving image data generated by the image processing unit 111 in the memory 104. On the other hand, the audio input unit 120 acquires a digital audio signal, and the audio processing unit 121 performs predetermined processing on the digital audio signal to generate audio data. Then, the control unit 101 temporarily stores the audio data generated by the audio processing unit 121 in the memory 104. Then, the control unit 101 transmits the moving image data and audio data stored in the memory 104 at a predetermined timing to the recording / reproducing unit 140 as stream data (moving image data stream). The recording / playback unit 140 writes the moving image data stream to the recording medium 141 (S302). This moving image data stream is the data of the mdat portion of the MOV file described with reference to FIG. 2, and the moving image data stream is sequentially added at a predetermined timing (S305 described later).

  Next, the control unit 101 performs a process of creating a new moov atom and temporarily storing it in the memory 104. This moov atom is the data that becomes the moov atom of the MOV file described with reference to FIG. 2, and the stco atom, stsc atom, stsz atom, and other necessary information corresponding to the moving image stream data recorded in S302 are stored. Included (S303).

  Then, the control unit 101 receives a shooting end instruction from the operation unit 102, and determines whether or not to shift to the shooting end state (S304). Then, if an instruction to end shooting is not input (No in S304), the recording / reproducing unit 140 is controlled to record a further moving image data stream on the recording medium 141 (S305). In S305, the control unit 101 transmits the moving image data and audio data sequentially stored in the memory 104 to the recording / reproducing unit 140 as stream data (moving image data stream) at a predetermined timing. The recording / playback unit 140 adds a new moving image data stream immediately after the moving image data stream already recorded in the recording 141 in the recording medium in S302 or the like.

  Next, the control unit 101 stores stco atom, stsc atom, stsz atom, and other necessary information in the moov atom created in S303 so as to correspond to the moving image data stream further recorded in S305. It is updated (S306).

  Thereafter, as long as shooting is not stopped, the control unit 101 performs control so as to execute the processing from S304 to S306.

  Next, when an instruction to stop shooting is input from the operation unit 102 (Yes in S304), the control unit 101 converts all moving image data and audio data remaining in the memory 104 as stream data (moving image data stream). And transmitted to the recording / reproducing unit 140. The recording / reproducing unit 140 appends the last moving image data stream immediately after the moving image data stream recorded in the recording 141 on the recording medium in S302, S305, etc. (S307).

  Next, the control unit 101 updates stco atom, stsc atom, stsz atom, and other necessary information in the moov atom created in S303 so as to correspond to the moving image data stream added in S307 ( S308). The processing from S302 to S308 is referred to as photographing processing S320.

  Due to the current shooting operation, only the moving image data stream has been recorded on the recording medium 141 so far. FIG. 4A shows the state of the FAT and data area of the recording medium 141 at this time. As shown in FIG. 4A, the moving image data stream is recorded across the areas of cluster numbers 1 and 2 in the data recording area by the current photographing operation. The FAT is set so as to read the area of cluster number 2 next to the area of cluster number 1, and is set to indicate that the file is the end in the area of cluster number 2. That is, “2” is set in the FAT area corresponding to cluster number 1 and “FF” is set in the FAT area corresponding to cluster number 2.

  Next, returning to FIG. When the update of the moov atom is completed, the control unit 101 checks whether the moov atom stored in the memory 104 has a data amount that is an integral multiple of the cluster size of the recording medium 141 (S309). In the FAT file system, the recording medium 141 can set the size of one cluster to 32 kilobytes, 16 kilobytes, 8 kilobytes, or the like. In S309, it is checked whether the moov atom is an integral multiple of these sizes. That is, if the size of one cluster is 32 kilobytes, it is checked whether it is 64 kilobytes, 704 kilobytes, or the like. If the moov atom stored in the memory 104 is not an integral multiple of the cluster size of the recording medium 141 (No in S309), for example, blank data ( free atom) is added after the moov atom. For example, if the moov atom is 17 kilobytes and the cluster size is 32 kilobytes, a 15 kilobyte free atom is generated and stored after the moov atom in the memory 104. Then, the size of the area (referred to as moov data) combining the moov atom and the free atom can be made an integral multiple of the cluster size (S310).

  Next, the control unit 101 transmits the moov atom or moov data including the moov atom stored in the memory 104 to the recording / playback unit 140 and records the data on the recording medium 141 as a file (moov file). Control. At this time, the control unit 101 assigns the file name, for example, MVI_0001. A moov file is recorded as the name of a moving image file such as MOV (S311).

  So far, the moving image data stream and the moov file are recorded on the recording medium 141. FIG. 4B shows the state of the FAT and data area of the recording medium 141 at this time. As shown in FIG. 4B, a moov file is recorded in cluster number 3. In the FAT, “FF” is set to indicate that there is a file recorded only in the area of the cluster number 3.

  Finally, the control unit 101 performs processing for combining the moving image data stream recorded on the recording medium and the moov file to complete the moving image file. In this embodiment, a process of rewriting only the FAT area is performed in order to combine the moving image data stream that has been separately recorded and the moov file. That is, the moov atom included in the moov file is read first, and then the moving image data stream is read (S312). FIG. 4C shows this changed state. In this embodiment, the location corresponding to the FAT cluster number 3 is changed from “FF” indicating the end of the file to “1” so that the cluster number 1 is read after the cluster number 3.

  By doing so, the data of the cluster number 3 comes first as the moving image data, and a moving image file in which “moov atom” is arranged at the head of the “MOV file” as shown in FIG. 2 is generated. Will be able to.

  When the processes from S301 to S312 are finished, the process returns to the standby state, and the recording process is finished. The processing from S309 to S312 is referred to as post-shooting processing AS330. In the normal moving image shooting mode, the imaging apparatus 100 according to the present embodiment generates a moving image file (“MOV file”) by performing the processing from S301 to S312.

  In the description of this embodiment, the directory entry is not mentioned, but the head cluster of the finally completed “MOV file” and the file name MVI — 0001. Information indicating the MOV is written in the directory entry. However, the file (cluster number 1 to 2) of the moving image data stream generated halfway does not have to be written in the directory entry. For the “moov file” (cluster number 3), the file name and the information of the first cluster are written in the directory entry for recording with a file name. In this embodiment, the file name of “moov file” is the same as the file name of “MOV file” to be finally completed, and the first cluster of “MOV file” is the head of “moov file”. Same as cluster. Therefore, when the “MOV file” is generated, the file can be completed by rewriting only the FAT area.

  Note that the file of the moving image data stream of this embodiment is recorded on the recording medium 141 with the file name “MVI — 0001.DAT”. Therefore, after the file is completed, the information indicating “MVI — 0001.DAT” written in the directory entry is deleted.

  Also, the moov atom information recorded in the memory 104 may be sequentially copied to a non-illustrated nonvolatile memory. By doing this, even when the power is suddenly turned off during movie shooting, the movie file of movie data that was in the process of being recorded is recorded using the moov atom information recorded in the nonvolatile memory when the imaging device is restarted. Can be completed.

<Continuous video shooting mode>
Next, the operation of the imaging apparatus 100 when performing moving image shooting in the continuous moving image shooting mode (second mode) of the present embodiment will be described with reference to FIGS. 5 to 11.

  FIG. 5 is a flowchart for explaining the operation of the imaging apparatus 100 when moving image shooting is performed in the continuous moving image shooting mode (second mode) of the present embodiment. These operations are basically controlled by the control unit 101 of the imaging apparatus 100. FIGS. 6, 7, and 8 show data written in each logical cluster of the recording medium 141 when the moving image is shot in the continuous moving image shooting mode (second mode) of this embodiment, and FAT. It shows the state of (file allocation table). In particular, FIG. 6 is a diagram for explaining the generation of the additionally-recorded moving image file in which newly captured moving image data (new moving image data) is added to the moving image file already recorded on the recording medium 141 (existing moving image file). . FIG. 7 is a diagram showing a confirmation screen after moving image shooting. FIG. 8 is a diagram for explaining the separation of new video data from the additional video file, generation of a video file only of video data (existing video data) of an existing video file, and generation of a new video file consisting of only new video data. FIG. FIG. 9 is a diagram for explaining separation of new moving image data, generation of a moving image file of only moving image data (existing moving image data) of the existing moving image file, and deletion of new moving image data from the additional moving image file.

  The continuous moving image shooting mode of the present embodiment will be described on the assumption that one shooting time is set in advance and “shooting time setting” is set for shooting. For example, the time length of the moving image data that can be set is 2 seconds, 4 seconds, 6 seconds, 8 seconds, etc., but may be any number of seconds. In addition, the present invention is not limited to shooting only for a length of time for which the shooting time is set, and the shooting time may be extended by instructing to extend shooting during shooting. It is not necessary to set.

  First, when the continuous moving image shooting mode is selected from the operation unit 102 of the imaging apparatus 100, the control unit 101 determines whether or not new moving image data to be shot can be added to the existing moving image data recorded on the recording medium 141. (S501). In this process, for example, whether or not additional recording is performed depending on whether or not the recording medium 141 is detached, whether or not the existing moving image file is protected, whether or not the moving image recording setting is the same as that of the existing moving image file, and the like. judge. Also, it is determined whether or not the sound recording setting associated with the moving image recording is the same as that of the existing moving image file, and whether or not the shooting time setting in the current continuous moving image shooting mode is the same as the shooting time setting of the existing moving image file. . Therefore, the control unit 101 refers to the path of the moving image file recorded in advance on the recording medium 141 when the imaging apparatus 100 is started up, and the moving image file captured last in the moving image file captured in the continuous moving image capturing mode. Is temporarily stored in a memory (not shown). And the control part 101 memorize | stores a write-once determination result in memory. Here, the conditions when it is not determined that “additional writing is possible” are organized.

When there is no additional recording target file A moving image shot in the continuous moving image shooting mode is added with an identifier of VSN called “VSN — 000X.MOV” and a 4-digit serial number as a file name. However, when the image capturing apparatus 100 is started up, if the name of the moving image file that was shot last among the moving image files shot in the continuous moving image shooting mode is not detected, additional recording is impossible.

When there is an insertion / extraction history of the recording medium 141 When the imaging apparatus 100 is activated, the control unit 101 records the history of the insertion / extraction of the recording medium 141 in the non-illustrated nonvolatile memory after the last shooting in the continuous moving image shooting mode. If it remains, appending is impossible. This is to reduce the possibility that “VSN — 000X.MOV” recorded on the recording medium 141 is edited by a computer or the like, the image size or the like is changed, and the moving image file itself is broken due to additional writing. For that purpose, the moov data of “VSN — 000X.MOV” to be added is read, and the shooting date / time information recorded in the moov atom is compared with the time information of the insertion / removal history remaining in the nonvolatile memory. The appending moving image file “VSN — 000X.MOV” is configured to record the first shooting time information in the moov atom among moving image data of a plurality of scenes recorded in the moving image.

When the existing video file to be added is protected When the “VSN_000X.MOV” to be added recorded on the recording medium 141 is protected, the file may not be modified by the user. Due to its high nature, no additional writing is possible.

When the file size exceeds a predetermined size due to additional recording The recording medium 141 is managed by, for example, the FAT file system as described above. In that case, for example, in FAT32, when it becomes 4 GB or more per file, it cannot be read. For this reason, if the “additional video file” exceeds 4 GB in the next shooting, the additional recording is impossible.

When the video playback time exceeds a predetermined time due to additional recording, the imaging device takes into account the case where it is not desired to take a video that exceeds a predetermined time (for example, 30 minutes). When the reproduction time of the moving image data of the “additional moving image file” exceeds 30 minutes, the additional writing is impossible. For this purpose, for example, if the playback time of the “additional video file” described in the moov atom is read out and 29 minutes 58 seconds or the like, the additional recording is impossible.

-When the video recording settings are not the same as the existing video file of the append source When adding new video data to the existing video file as in this embodiment, the frame rate, image size, GOP configuration, If the moving image encoding method is changed, there is a possibility that seamless playback cannot be performed. For this reason, when the moving image data of the existing moving image file and the moving image recording setting of the new moving image data are not the same, additional recording is impossible. Information such as a frame rate, an image size, a GOP configuration, and a moving image encoding method is recorded in a moov atom or a file header of an existing moving image file.

-When the audio recording settings are not the same as the existing video file of the original recording source When adding new video data to the existing video file as in this example, the audio sampling rate or audio encoding is performed in the middle of the video. If the method or the like is changed, reproduction may not be possible. Therefore, when the moving image data of the existing moving image file and the audio recording setting of the new moving image data file are not the same, additional recording is impossible. Information such as an audio sampling rate and an audio encoding method is recorded in a moov atom or a file header of an existing moving image file.

When the “shooting time setting” is not the same as the existing moving image file of the appending source As described above, the image pickup apparatus of the present embodiment captures moving image data shot for a fixed time of 2 seconds, 4 seconds, 6 seconds, 8 seconds, etc. The method of appending is taken. As will be described later, for this reason, an additional recording moving image file in which only moving image data of 4 seconds is added is generated, and fast forwarding and rewinding of the file are performed by fast forwarding and rewinding every 4 seconds. For this reason, when the set “shooting time setting” is not the same as the existing moving image file of the additional recording source, the additional recording is impossible. Information regarding this “shooting time setting” is also described in a moov atom, a file header, or the like.

  The above is the condition that makes additional writing impossible.

  Next, when a shooting start instruction is input from the operation unit 102 (Yes in S502), the control unit 101 transmits a shooting start instruction to each block of the imaging apparatus to start moving image shooting. Then, the process of S320 in FIG. 3 is continued until an instruction to end photographing is given. That is, the control unit 101 sequentially records a moving image data stream on the recording medium 141, generates a moov atom corresponding to the moving image data stream, and stores it in the memory 104 until a shooting end instruction is input. To do. When an instruction to end shooting is input, the last shot moving image data and audio data are further recorded on the recording medium 141 as a moving image data stream. Then, the moov atom corresponding to the moving image data stream stored in the memory 104 is updated.

  When the shooting process S320 ends, the control unit 101 next reads out the result of the additional recording determination process determined in S501 before shooting from the memory of the control unit 101. If additional writing is possible, the control unit 101 moves the process to S510 (addition in S503). On the other hand, if additional recording is not possible, the process moves to post-shooting processing AS330 as new shooting (new in S503). The description of S330 is the same as the description of FIG. A file name “VSN — 000X.MOV” is assigned to a moving image file shot in the continuous moving image shooting mode.

  Next, a case where additional writing is possible (addition in S503) will be described. When additional recording is possible, the control unit 101 records a stream of new video data in an empty cluster where the existing video file “VSN — 000X.MOV” to be additionally recorded is not recorded, as shown in FIG. In this manner, the recording / reproducing unit 140 is controlled. In the present embodiment, an example in which data is recorded in the data area of cluster number 4 on the recording medium 141 is shown, but any cluster may be used as long as it is a free area. At this time, a file name obtained by incrementing the 4-digit serial number of the file name of “existing moving image file”, “VSN — 000X + 1.DAT”, is used for the file of the new moving image data stream.

  When the additional recording is possible, the control unit 101 controls the recording / reproducing unit 140 to read the moov data of the existing moving image file to be added from the recording medium 141 and stores the moov atom of the existing moving image file in the memory 104 ( S510). Then, the process of combining the new moving image data stored in the memory 104 with the moov atom is performed by the current photographing process S320 (S511). As described with reference to FIG. 2, the moov atom stores the creation date and time of the moving image and offset information to the chunk indicating the frame of each moving image. Therefore, the control unit 101 generates a moov atom that is combined using two moov atoms so that the next chunk after the last chunk of the existing moving image data becomes the first chunk of the new moving image data. Specifically, processing such as adding the offset value of “stco atom” of the existing moving image data to the offset value of “stco atom” of the new moving image data is performed. By doing so, it is possible to generate a moov atom necessary for reproducing a moving image file in which new moving image data is added to an existing moving image file. At this time, the time of moving image shooting can be recorded in the newly generated moov atom, but the shooting time information of the moving image data of the existing moving image file is recorded in the moov atom of the added moving image. Will be.

  Next, the control unit 101 creates moov data including a moov atom by the same processing as S309 to S310 in FIG.

  Then, the control unit 101 transmits the combined moov atom or moov data including the combined moov atom stored in the memory 104 to the recording / playback unit 140, and stores the file (moov file) in the recording medium 141. (S512). At this time, the control unit 101 controls the recording / reproducing unit 140 so that the recording medium 141 overwrites the moov data of the already recorded moving image file. Alternatively, the moov data of the existing moving image file may be deleted, and new moov data may be recorded in another cluster.

  So far, the moving image data stream and the moov file are recorded on the recording medium 141. FIG. 6B shows the state of the FAT and data area of the recording medium 141 at this time. Incidentally, FIG. 6A shows the state of the data area of the existing moving image file already recorded on the recording medium 141 and the state of the FAT area. In FIG. 6A, the existing moving image file “VSN — 000X.MOV” is recorded in the data area of cluster numbers 1 to 3. The FAT is set to read the files in the order of cluster number 3> 1> 2.

  In FIG. 6B, from the state of FIG. 6A, first, a newly captured new video data stream is recorded in the areas of cluster numbers 4 and 5, and FAT is stored in the area of cluster number 4. Subsequently, it is set so that the area of cluster number 5 is read. The file name of this new moving image data stream is a file name obtained by incrementing the 4-digit serial number of the file name of “existing moving image file”, “VSN — 000X + 1.DAT” as described above. Further, the moov atom area is larger than that shown in FIG.

  Next, the control unit 101 combines the existing moving image data stream recorded on the recording medium, the new moving image data stream, and the moov file, and completes the moving image file (S513). In this embodiment, a process of rewriting only the FAT area is performed in order to combine the newly recorded new moving image data stream file and the existing moving image data of the existing moving image file. That is, a change is made so that the stream of the new moving image data can be read after the stream of the existing moving image data of the existing moving image file. FIG. 6C shows this changed state. In the present embodiment, after the cluster number 2 which is the end of the existing moving image data stream, the location corresponding to the FAT cluster number 2 is indicated at the end of the file so that the cluster number 4 which is the first of the new moving image data stream is read. “FF” is changed to “4”. Then, the “additional video file” is read in the order of 3> 1> 2> 4> 5 according to the FAT. The file name “VSN — 000X.MOV” is used for the “additional video file” in the same manner as the “existing video file”.

  By doing in this way, the imaging apparatus 100 of a present Example can produce | generate the moving image (additional moving image file) added to the existing moving image file by rewriting FAT after recording of new moving image data is completed. . By creating such an additional video file, even an imaging device that cannot seamlessly reproduce multiple files of video data can seamlessly combine the video data of an existing video file and the video data obtained by new shooting. Can be played.

  When generating these moving image files, the imaging apparatus 100 according to the present embodiment records time information of “shooting time setting” that is initially set as a moov atom or moov data. That is, for example, by confirming the moov atom of the additionally recorded moving image file, it can be detected that the moving image file has been additionally recorded every 4 seconds of moving image data images. Similarly, 2 seconds, 6 seconds, and 8 seconds can also be detected.

  Next, the control unit 101 displays the moving image data of the additional recording moving image file recorded on the recording medium 141 on the display unit 130 (S520). For this purpose, the control unit 101 controls the recording / reproducing unit 140 so as to read the additionally-recorded moving image file recorded on the recording medium 141 from the recording medium 141. The control unit 101 reads a moov atom or the like of the read additional movie file. Then, the control unit 101 uses the offset value when the moov atom is combined in S511 to identify the chunk corresponding to the first frame of the new moving image data that was captured last, and the image processing unit determines the image signal of that frame. 111 to decrypt. Then, the image processing unit 111 stores the image signal of the first frame of the decoded new moving image data in a memory (not shown), and the control unit 101 controls the display control unit 131 to read out the image signal from the memory, and the display control unit 131 displays an image on the display unit 130 (S520).

  This confirmation screen is shown in FIG. In this screen, the control unit 101 displays items of “play”, “save”, “new”, and “delete” on the display unit 130 so that the user can operate while viewing this screen. In this way, the display control unit 131 is controlled. When the user operates the operation unit 102 to select “play”, the combined video image file can be played by the processing up to S513. When “playback” is selected, the control unit 101 controls the display control unit 131 to display a display as shown in FIG. 7B on the display unit 130. In this screen, on the display screen, the playback of the portion of the “additional video file” that corresponds to the newly captured new video data stream is started. For this purpose, the control unit 101 refers to the moov atom, specifies the offset of the chunk of the frame image to be sequentially read, and controls the recording / reproducing unit 140 to read the chunk from the recording medium 141. Here, when “previous skip” and “post skip” displayed on the screen are selected, the control unit 101 stores the video data corresponding to the time of “shooting time setting” recorded in the moov atom of the additional video file. To skip before or after. That is, when the “shooting time setting” is 4 seconds and the moving image data of the additional recording moving image file is composed of moving image data of 4 seconds, the moving image data can be skipped every 4 seconds. Further, when the “shooting time setting” is 2 seconds and the moving image data of the additional recording moving image file is composed of moving image data of 2 seconds, the moving image data can be skipped every 2 seconds. For example, it is an “additional video file” in which 5 scenes of 4 seconds are joined together, and a 2-second scene (the scene at the time of 18 seconds in the entire video) of the newly captured new video data is played back. When “Skip Previous” is operated, the following operations are performed. That is, as shown in FIG. 7C, the control unit 101 skips the “additional video file” being played back by 4 seconds before, and displays the scene at the time of 14 seconds. FIG. 7C is not the latest moving image data photographed last, but the moving image data photographed one time before that. That is, instead of moving to the first frame of each scene, skipping can be performed in units of seconds of each scene set before shooting on the moving image data of the additional recording moving image file. At this time, the control unit 101 analyzes the moov atom, specifies the recording position of the chunk of the frame image at the time of 14 seconds, and performs control so that the moving image is reproduced from that position.

  Returning to FIG. 7A, the description will be continued. When “save” is selected (save in step S530), the control unit 101 keeps the “additional video file” recorded on the recording medium 141 in the process up to step S513, and erases the display of FIG. The display control unit 131 is controlled (S540). And it controls to return each part of the imaging device 100 to a standby state again.

  Further, when “new” is selected (new in S530), the control unit 101 performs a process of separating the “additional video file” recorded on the recording medium 141 in the processes up to S513 into two (S550). . For this purpose, first, the control unit 101 uses the offset value when the moov atom developed in the memory 104 is combined to specify the recording position of the chunk corresponding to the first frame of the newly captured video data. (S551). That is, the position (cluster number 4, 5) corresponding to the new moving image data stream of the “additional moving image file” recorded on the recording medium 141 in the state shown in FIG.

  Then, the control unit 101 controls the recording / reproducing unit 140 to rewrite the FAT area of the recording medium 141 so as to separate the data area corresponding to the new moving image data stream from the “additional moving image file” (S552). The file name of the separated new moving image data stream is assumed to be “VSN — 000X + 1.DAT”. This situation will be described with reference to FIG. 8. In the state shown in FIG. 8A, the “additional video file” recorded on the recording medium 141 corresponds to the new video data stream after the cluster number 2. The cluster number 4 to be read is read. Here, by the processing in S552, as shown in FIG. 8B, the table corresponding to the cluster number 2 in the FAT area is rewritten from “4” to “FF” in order to set the cluster number 2 to the end of the file.

  Then, the control unit 101 regenerates the moov atom corresponding to the existing moving image data stream originally recorded on the recording medium 141, adjusts the size as in S309 and S310, and records the moov data on the recording medium 141. . At this time, after the moov data of the “additional video file” is deleted, the moov data including the moov atom corresponding to the recreated existing video data stream is recorded on the recording medium 141 (S553). In this embodiment, the data is recorded in the data area of cluster number 3 as shown in FIG. The file name “VSN — 000X.MOV” is used as the moov data file. In this way, preparation is made for generating a moving image file that is substantially the same as the “existing moving image file” originally recorded on the recording medium 141.

  In addition, the control unit 101 regenerates a moov atom corresponding to the separated new moving image data, adjusts the size of the generated moov atom as in S309 and S310, and creates moov data in a new data area of the recording medium 141. Recording is performed (S554). In this embodiment, the data is recorded in the data area of cluster number 6 as shown in FIG. The file name of the moov data is assumed to be “VSN — 000X + 1.MOV”. In this way, preparations for generating a moving image file of “new moving image file” are made.

  FIG. 8B shows the state of the recording medium 141 at this time. In FIG. 8B, the existing moving image data stream is recorded across the areas of cluster numbers 1 and 2 in the data recording area. The FAT is set to read in the order of cluster number 1> 2, and is set to indicate that the file is the end in the area of cluster number 2. That is, “2” is set in the FAT area corresponding to cluster number 1 and “FF” is set in the FAT area corresponding to cluster number 2. Further, the new moving image data stream is recorded across the areas of cluster numbers 4 and 5 in the data recording area. The FAT is set to read in the order of cluster number 4> 5, and is set to indicate that the file is the end in the area of cluster number 5. That is, “5” is set in the FAT area corresponding to the cluster number 4, and “FF” is set in the FAT area corresponding to the cluster number 5. The moov atom corresponding to the existing moving image data stream is recorded in the data area of cluster number 3, and the moov atom corresponding to the new moving image data stream is recorded in the data area of cluster number 6.

  Next, a process of completing the “existing moving image file” and the “new moving image data file” is performed (S555) (S556). For this purpose, the control unit 101 rewrites the FAT area of the recording medium 141 by controlling the recording / reproducing unit 140 as in S312 and S513. FIG. 8C shows this changed state. In this embodiment, the location corresponding to the FAT cluster number 3 is changed from “FF” indicating the end of the file to “1” so that the cluster number 1 is read after the cluster number 3. As a result, the “existing moving image file” is read in the order of cluster number 3> 1> 2. Further, the location corresponding to the FAT cluster number 6 is changed from “FF” indicating the end of the file to “4” so that the cluster number 4 is read after the cluster number 6. As a result, the “new moving image file” is read in the order of cluster number 6> 4> 5.

  As described above, the control unit 101 can read the moov atom of the moving image file recorded on the recording medium 141, change and newly create it, write it again on the recording medium 141, and rewrite the data in the FAT area. As a result, a “new movie file” (VSN_000X + 1.MOV) is generated from the “additional movie file” (VSN_000X.MOV), and is substantially the same as the “existing movie file” (VSN_000X.MOV) originally recorded on the recording medium 141. The same movie file can be generated.

  In addition, when “delete” is selected (deleted in S530), the control unit 101 separates the “additional video file” recorded in the recording medium 141 in the process up to S513 into two, and deletes the new video data A process of (invalid) is performed (S560). For this purpose, first, the control unit 101 performs the processing from S551 to S553.

  Next, the control unit 101 performs processing for deleting a file of the new moving image data stream (S561). Therefore, in order to invalidate the moving image data stream corresponding to the separated new moving image data, the control unit 101 has no file recorded in the FAT corresponding to the cluster numbers 4 and 5 in the data area of the recording medium 141. Set the information indicating that. As a result, the new moving image data stream file is handled as deleted in the FAT.

  FIG. 9B shows the state of the recording medium 141 at this time. In FIG. 9B, the existing moving image data stream is recorded across the areas of cluster numbers 1 and 2 in the data recording area. The FAT is set so as to read the area of cluster number 2 next to the area of cluster number 1, and is set to indicate that the file is the end in the area of cluster number 2. That is, “2” is set in the FAT area corresponding to cluster number 1 and “FF” is set in the FAT area corresponding to cluster number 2. In addition, the new moving image data stream is recorded over the areas of cluster numbers 4 and 5 in the data recording area, but is invalid. Therefore, FAT is set to indicate that no data image is recorded in the areas of cluster numbers 4 and 5. That is, “0” is set in the FAT area corresponding to the cluster numbers 4 and 5. The moov atom corresponding to the existing moving image data stream is recorded in the data area of cluster number 3.

  Next, the process S555 for completing the “existing video file” is performed. FIG. 8C shows this state. In this embodiment, the location corresponding to the FAT cluster number 3 is changed from “FF” indicating the end of the file to “1” so that the cluster number 1 is read after the cluster number 3. As a result, the “existing moving image file” is read in the order of cluster number 3> 1> 2.

  As described above, the control unit 101 can read the moov atom of the moving image file recorded on the recording medium 141, change it, write it again on the recording medium 141, and rewrite the data in the FAT area. As a result, it is possible to generate substantially the same moving image file as the “existing moving image file” (VSN_000X.MOV) originally recorded on the recording medium 141 from the “additional moving image file” (VSN_000X.MOV).

  When the processes from S550 to S556 and S560 to S555 are completed, the control unit 101 moves the process to S540 and controls the display control unit 131 to turn off the display of FIG. 7 (S540). And it controls to return each part of the imaging device 100 to a standby state again.

  As described above, according to the imaging apparatus of the present embodiment, in the normal moving image shooting mode (first mode), moving image data shot from the start to the end of one moving image shooting is used as one file. It can be recorded on a recording medium. In the continuous movie shooting mode (second mode), a movie file in which newly recorded movie data (new movie data) is added to a movie file (existing movie file) already recorded on the recording medium. (Additional video file) can be recorded on a recording medium. In particular, in the continuous moving image shooting mode, the image pickup apparatus according to the present embodiment can display a moving image on the display screen after shooting to allow the user to confirm the image. At this time, the imaging apparatus of the present embodiment can seamlessly reproduce and display the moving image data (existing moving image data) of the existing moving image file and the new moving image data. Then, after confirming the video continuously played by the user, it is possible to select a process such as recording the additional video file, recording the new video data as another file, or deleting the new video data.

  According to the imaging apparatus of the present embodiment, even if the imaging apparatus cannot seamlessly reproduce a plurality of files of moving image data, the existing moving image data and the new moving image data are seamlessly added immediately after a new moving image is captured. Can be played and displayed. Then, according to the process selected by the user at this time, it is possible to record the additionally recorded moving image file, record the new moving image data as another file, or delete the new moving image data. Therefore, the imaging apparatus of the present embodiment can improve usability for the user while avoiding an increase in cost.

  Here, when adding new movie data to the “existing movie file” in the continuous movie shooting mode, an irregular error occurs, and the processing for the case where the shooting for the time of one scene set before shooting cannot be performed ( “Error handling”) will be described.

  The time of one scene here is the shooting time of one scene set in the above-mentioned “shooting time setting”, and as described above, for example, 2, 4, 6, 8 seconds or the like can be set. is there.

  In the continuous moving image shooting mode, the imaging apparatus 100 according to the present embodiment can reproduce and display an “additional moving image file” in which newly captured new moving image data is added to an existing moving image file at the end of shooting (FIG. 5). S520, FIG. 7). At this time, as described above, the moving image data is skipped forward or backward by the amount of “shooting time setting” stored in the moov atom of the “additional moving image file”. That is, when the “shooting time setting” is 4 seconds and the moving image data of the additional recording moving image file is composed of moving image data of 4 seconds, the moving image data is 4 seconds (for each preset time length). You can skip.

  If a scene with a length other than “Shooting time setting” is included in the middle despite such skipping, even if you want to check only the first image of each scene with the skip operation, It will end up. If it does so, operation will become inconvenient for a user.

  Therefore, the imaging apparatus 100 according to the present exemplary embodiment can perform shooting so that a scene having a length other than “shooting time setting” is not included in at least a halfway scene of one “additional video file”. ing. Here, the reason for the intermediate scene is that, for example, the last scene of the “additional video file” may have a length other than “shooting time setting”. This is because there is no problem in confirming only the top image of each scene by the skip operation immediately after the last shooting.

  In addition, when an error occurs here, for example, when a cover of the storage unit of the recording medium 141 is opened or a shooting stop switch is pressed during moving image shooting. The “error process” described here is a process in the case where an error occurs during the shooting process of S320 in FIG. FIG. 10 shows the state of a moving image generated by each error process, and each block corresponds to a moving image of one scene. The shaded blocks indicate moving images that have been shot due to irregular errors.

  Since a plurality of processes can be considered for “error processing”, each will be described, but any type of “error processing” may be used.

In the case where “error processing A” additional recording processing is executed Here, as in the processing from S502 to S513 in FIG. File ". However, unlike FIG. 5, the confirmation screen as shown in FIG. 7A is not displayed. Therefore, as shown in FIG. 10A, new movie data is added to the “existing movie file” to generate an “additional movie file” (VSN — 000X.MOV).

  However, if you add the movie data of the scene to be shot after that, a scene with a length other than the “shooting time setting” will be included in the middle as described above, and only the first image of each scene will be included. Even if you want to confirm by skip operation, it will be shifted. Therefore, in order to avoid such a situation in the error processing A, the control unit 101 does not add the video data to be photographed next to (VSN_000X.MOV) as a new video file as a recording medium. 141 is recorded.

In the case where “error processing B” separation processing is executed Here, processing for recording new moving image data on a recording medium is performed in the same manner as the processing from S502 to S320 in FIG. However, the “new movie file” is created without adding the new movie data whose shooting has been stopped midway to the “existing movie file”. That is, when the photographing stops due to an irregular error, the control unit 101 performs the process of S330 following S320 of FIG. Also at this time, the confirmation screen as shown in FIG. Therefore, as shown in FIG. 10B, the “existing moving image file” (VSN_000X.MOV) and the “new moving image file” (VSN_000X + 1.MOV) are recorded on the recording medium 141.

  However, if you add the movie data of the scene to be shot after that, a scene with a length other than the “shooting time setting” will be included in the middle as described above, and only the first image of each scene will be included. Even if you want to confirm by skip operation, it will be shifted. Therefore, in order to avoid such a situation in the error processing B, the control unit 101 does not add the video data to be captured next to (VSN — 000X + 1.MOV) as a new video file as a recording medium. 141 is recorded.

  In another case, the moving image data to be photographed next may be added to the original “existing moving image file” (VSN — 000X.MOV).

  In another case, if it is possible to include a scene of a length other than “shooting time setting” at the beginning, the movie data (VSN — 000X + 1.MOV) created this time is used for the movie data to be shot next. ) May be added.

In the case where the “error process B” deletion process is executed Here, the process of recording the new moving image data on the recording medium is performed as in the processes from S502 to S320 of FIG. However, the new moving image data is deleted without adding the new moving image data whose shooting has been stopped halfway to the “existing moving image file”. That is, when the shooting is stopped due to an irregular error, the control unit 101 performs the same processing as S561 etc. following S320 in FIG. 5, and uses the FAT area information to create new moving image data. A process of deleting the recorded moving image data of the cluster area is executed.

  Also at this time, the confirmation screen as shown in FIG. Therefore, as shown in FIG. 10B, the “existing moving image file” (VSN — 000X.MOV) remains on the recording medium 141, and the file relating to the new moving image data is not recorded.

  In this case, even if the moving image data of a scene to be captured later is added to the “existing moving image file” (VSN — 000X.MOV), a scene having a length other than “shooting time setting” is not included in the middle. Therefore, the moving image data to be photographed next is added to the “existing moving image file” (VSN_000X.MOV).

  In another case, the control unit 101 may record the moving image data to be photographed next on the recording medium 141 as a new moving image file (VSN_000X + 1.MOV).

  The above is the description of “error processing”.

  In addition, when the moving image data to be photographed next is recorded as a new moving image file by “error processing”, it is determined in the processing of S501 in FIG. 5 that it is impossible to add to the header such as a moov atom of moving image data. It is sufficient to record the flag to be used.

  As described above, in the continuous movie shooting mode, when a scene is repeatedly shot for a predetermined time and then appended, it is not possible to shoot for the time of one scene set before shooting due to an irregular error. If it does, error processing is performed. By this error processing, it is possible to prevent a scene that is less than the predetermined time from being included in the “additional video file” composed of a plurality of scenes. That is, it is possible not to include a scene that is less than the predetermined time in the “additional video file”. Alternatively, even if the “additional video file” includes a scene that is less than the predetermined time, it can be the first scene or the last scene.

  According to such error processing, the user can perform a skip operation with a little uncomfortable feeling when performing a skip search for the “additional video file” composed of a plurality of scenes of a predetermined time.
