  Hereinafter, processing for recording image data on the disk 113 and processing for erasing the recorded image data executed in the video camera 100 will be described.

  FIG. 2 is a time chart showing an outline of the process of recording image data on the disk 113 and the process of erasing the recorded image data executed in the video camera 100.

  As shown in FIG. 2, when the user presses the START / STOP switch 116 during imaging, an image data recording process for recording image data on the disk 113 is executed in the recording / reproduction data processing circuit 103 under the control of the system controller 111. Is done.

  Specifically, when the START / STOP switch 116 is pressed, first, input image data, which is image data input from the image signal processing circuit 102, is sequentially transferred to each predetermined data capacity (CMB). The data are alternately stored in the buffer 114 and the buffer 115 of the memory 109. On the other hand, when a predetermined amount of image data is stored in the buffers 114 and 115, the stored image data is alternately read from the buffers 114 and 115 sequentially and recorded on the disk 113 at a predetermined speed (n-times speed).

  That is, as shown in FIG. 2, when the START / STOP switch 116 is pressed, the image data A for the first predetermined capacity among the input image data from the image signal processing circuit 102 is stored in the buffer 114. When the accumulation of the image data A in the buffer 114 is completed, a predetermined amount of image data B following the inner image data A of the input image data is accumulated in the buffer 115, and the image data A accumulated in the buffer 114 is n times faster. To record on the disk 113.

  Next, when the accumulation of the image data B in the buffer 115 is completed, the predetermined amount of image data C following the inner image data B of the input image data is accumulated in the buffer 114, and the image data B accumulated in the buffer 115 is stored. Recording on the disk 113 at n-times speed. When the accumulation of the image data C in the buffer 114 is completed, the image data D for a predetermined capacity following the inner image data C of the input image data is accumulated in the buffer 115, and the image data C accumulated in the buffer 114 is n times faster. To record on the disk 113.

  As described above, in the image data recording process, the input image data is alternately accumulated in the buffers 114 and 115 for each predetermined capacity, and the image data is alternately outputted from the buffers 114 and 115 every time the accumulation in the buffers 114 and 115 is completed. Is read and recorded on the disk 113, and this process is repeated. As a result, the input image data is recorded on the disk 113.

  If the START / STOP switch 116 is pressed again during the above-described image data recording process, the image data recording process of the image data on the disk 113 is stopped.

  As described above, since the recording of the image data on the disk 113 is performed at the n-times speed, the time tr during which the predetermined amount of image data stored in the buffers 114 and 115 is recorded on the disk 113 is included in the input image data. The predetermined amount of image data (image data A, B, C, etc.) is 1 / n time (tr = ts / n) of the time tssec stored in the buffers 114 and 115. Accordingly, in the image data recording process on the disk 113, the actual recording time tr on the disk 113 for each predetermined amount of image data stored in the buffers 114 and 115 is ts / nsec, and the remaining time (ts (1 -1 / n) sec) is the recording standby time.

  For example, the image data recording process of the image data A accumulated in the buffer 114 is performed at ts / nsec after the accumulation of the image data A in the buffer 114 is completed, and the image data recording process of the image data B is performed as the image data B Is stored in the buffer 115, that is, after tssec. As described above, a recording standby time of ts (1-1 / n) sec occurs after the image data A is recorded on the disk 113 until the image data B is recorded on the disk 113.

  Further, in the video camera 100, the user can erase the image data after the start of the image data recording process already recorded on the disk 113 by pressing the recording cancel switch 117 during the image data recording process. . Specifically, when the user depresses the recording cancel switch 117 during the image data recording process, the system controller 111 displays images from when the START / STOP switch 116 is already recorded on the disk 113 to when the recording cancel switch 117 is depressed. Content erasure processing for erasing recorded content that is data is instructed, and content erasure processing is executed in the recording / reproduction data processing circuit 103. This content erasing process is executed using the recording standby time over the above-described ts (1-1 / n) sec. For this reason, the image data recording process is executed even if the content erasing process is executed.

  The content erasing process will be specifically described below.

  As shown in FIG. 2, for example, when the recording cancel switch 117 is pressed while the image data D is stored in the buffer 115, the storage of the image data D in the buffer 115 is stopped halfway, and the recording cancel switch 117. The above-described image data recording process is executed on input image data after a recording cancel instruction when is pressed. Then, during the recording standby time during the storage of the first predetermined amount of image data D ′ in the buffer 114 among the input image data after the recording cancel instruction, the recording cancel instruction is issued after the start of the image data recording process. The recorded content recorded immediately before, that is, the image data A to C recorded on the disc 113 from when the START / STOP switch 116 is pressed to when the recording cancel switch 117 is pressed is erased from the disc 113. Then, after the recording standby time has elapsed, the image data D ′ accumulated in the buffer 114 is recorded on the disk 113, and thereafter normal image data recording processing is executed.

  Hereinafter, content erasure processing executed in the video camera 100 will be described.

  FIG. 3 is a flowchart of key interrupt processing executed by the system controller 111, and FIG. 4 is a flowchart of recording standby processing executed by the system controller 111. The key interruption process and the recording standby process constitute a content erasing process.

  In the key interrupt process, as shown in FIG. 3, first, it is determined whether or not the recording cancel switch 117 is pressed (step S1). If the recording cancel switch 117 is not pressed, this process ends. On the other hand, if the recording cancel switch 117 is pressed, the recording cancel flag is set to the ON state (step S2), and this process is terminated.

  On the other hand, in the recording standby process, as shown in FIG. 4, first, it is determined whether or not the recording cancel flag is in an ON state (step S11). If the recording cancel flag is not in an ON state, this process is terminated. On the other hand, if the recording cancel flag is in the ON state, the erasing process routine is called to execute the erasing process (step S12), the recording cancel flag is set to the OFF state (step S13), and this process is terminated.

  In the erasing process in step S12, the immediately previous recorded content is read from the disc 113 during the recording standby time immediately after it is determined in step S11 that the recording cancel flag is in the ON state (at the time of recording cancel instruction) as described above. to erase. At this time, the currently executed image data recording process is stopped, and an instruction to start the image data recording process after the recording cancel instruction is given.

  As described above, when the recording cancel switch 117 is pressed during the image data recording process and a recording cancel instruction is issued (Yes in step S11), the erasing process is performed during the recording standby time immediately after the recording cancel instruction. The recorded content from the start of the image data recording process to the time of the recording cancel instruction is erased from the disc 113 (step S12), while the image data recording process is performed on the input image data after the recording cancel instruction. Therefore, the input image data after the recording cancel instruction is recorded on the disk 113.

  As described above, according to the video camera 100 according to the present embodiment, when the recording cancel switch 117 is pressed during the image data recording process and a recording cancel instruction is given, the content erasing process is executed, and the recording cancel instruction During the recording standby time immediately after the recording, the recorded content from the start of the image data recording process to the recording cancel instruction is erased from the disk 113, and the input image data after the recording cancel instruction is recorded on the disk 113. Therefore, the user can erase the image data recorded on the disk 113 by just pressing the recording cancel switch 117 while continuing the image data recording process.

  Therefore, even when the recording capacity of the disk 113 is reduced during shooting, the user depresses the recording cancel switch 117 and erases the image data recorded on the disk 113 until just before that, so that the disk 113 is removed. Recording capacity can be secured without replacement. Thereby, the user can continue shooting without missing a shooting opportunity, and can perform comfortable shooting.

  The image recording / reproducing apparatus according to the second embodiment of the present invention will be described below. The image recording / reproducing apparatus according to the present embodiment differs from the image recording / reproducing apparatus according to the first embodiment described above only in the content erasing process, and the configuration and the like are the same. In the following, the same components as those in the image recording / reproducing apparatus according to the first embodiment are denoted by the same reference numerals, and redundant description will be omitted, and only different parts will be described.

  Hereinafter, the content erasing process executed in the video camera 100 as the image recording / reproducing apparatus according to the present embodiment will be described.

  FIG. 5 is a time chart showing an outline of the process of recording image data on the disk 113 and the process of erasing the recorded image data executed in the video camera 100.

  Since the video camera 100 executes the same image data recording process as that of the video camera 100 according to the first embodiment described above, the description of the image data recording process is omitted. For convenience of the following description, in the image data recording process, a process of storing a predetermined amount of input image data in one of the buffer 114 and the buffer 115 and recording the stored predetermined amount of image data on the disk 113 is performed. This is called one recording cycle.

  Hereinafter, the content erasing process in the present embodiment will be described.

  In the video camera 100, every time the user depresses the recording cancel switch 117 once during the image data recording process, the recorded / reproduced data processing circuit 103 is already recorded on the disk 113 under the control of the system controller 111. A content erasing process is executed in which only the image data recorded in the immediately preceding recording cycle is erased. This content erasing process is executed using the above-described recording standby time of ts (1-1 / n) sec. For this reason, the image data recording process is executed even if the content erasing process is executed.

  Hereinafter, the content erasing process in the present embodiment will be specifically described.

  As shown in FIG. 5, for example, when the recording cancel switch 117 is pressed once while the image data D is stored in the buffer 115, the storage of the image data D in the buffer 115 is interrupted, and the recording cancel switch 117 is pressed. The above-described image data recording process is continued for input image data after the recording cancel instruction when is pressed. Then, during the first recording standby time which is the recording standby time in the recording cycle for the image data D ′ having the first predetermined capacity among the input image data after the recording cancel instruction, the latest one time before the recording cancel instruction. The first most recently recorded image data, that is, image data C, which is the image data recorded on the disk 113 in the first most recent recording cycle, is erased from the disk 113, and is stored in the buffer 114 after the first recording standby time has elapsed. The stored image data D ′ is recorded on the disk 113, and thereafter normal image data recording processing is executed.

  Further, as shown in FIG. 5, for example, when the recording cancel switch 117 is pressed twice while the image data D is stored in the buffer 115, first, as described above, the first recording cancel switch 117 is pressed. In response to the recording cancel instruction, the first most recent image recording data (image data C) is erased from the disk 113 during the first recording standby time, and the image data stored in the buffer 114 after the first recording standby time has elapsed. D ′ is recorded on the disk 113.

  Similarly, during the second recording standby time, which is the recording standby time in the recording cycle for the predetermined amount of image data E following the internal image data D ′ of the input image data, the first most recent recording is performed before the recording cancel instruction. The second most recently recorded image data, that is, the image data B, which is the image data recorded on the disk 113 in the second most recent recording cycle, which is the most recent recording cycle before the cycle, is erased from the disk 113, and after the second recording standby time has elapsed. Records the image data E stored in the buffer 114 on the disk 113, and thereafter executes a normal image data recording process.

  As described above, in the content erasing process, the first recording standby time, the second recording standby time,... The recorded image data such as the latest recorded image data, the second recorded image data,.

  In this content erasing process, the number of the latest recorded image data corresponding to the number of times the recording cancel switch 117 is pressed may be deleted during the recording standby time in the recording cycle in which the recording cancel switch 117 is pressed. . Specifically, as shown in FIG. 5, in the first recording cycle immediately after the recording cancel instruction, when the recording cancel switch 117 is pressed twice, the first and second recordings are performed during the first recording standby time. The most recently recorded image data may be erased from the disk 113.

  Hereinafter, content erasure processing executed in the video camera 100 will be described.

  FIG. 6 is a flowchart of key interrupt processing executed by the system controller 111, and FIG. 7 is a flowchart of recording standby processing executed by the system controller 111. The key interruption process and the recording standby process constitute a content erasing process.

  In the key interruption process, as shown in FIG. 6, it is first determined whether or not the recording cancel switch 117 has been pressed (step S21). If the recording cancel switch 117 has not been pressed, this process ends. On the other hand, if the recording cancel switch 117 is pressed, the count value of a recording cancel counter (not shown) included in the system controller 111 that counts the number of times the recording cancel switch 117 is pressed is incremented by 1 (step S22), and this process is terminated. To do.

  On the other hand, the recording standby process is executed every recording cycle. As shown in FIG. 7, first, it is determined whether or not the count value of the recording cancel counter is 0 (step S31). If it is 0, this process is terminated. On the other hand, if the count value is not 0, the erasing process routine is called to execute the erasing process (step S32), the count value of the recording cancel counter is decremented by 1 (step S33), and this process is terminated.

  In the erasing process in step S32, the first recording cancel instruction by pressing the first recording cancel switch 117 from the image data recorded on the disk 113 during the recording standby time of the recording cycle currently being executed. The image data recorded in the previous recording cycle before the time is erased. The time when the first recording cancel switch 117 is pressed is, for example, the time when it is determined that the count value is not 0 for the first time after the count value is determined to be 0 in step S31.

  When the erasing process in step S32 is performed in response to the first recording cancel instruction, the image data recording process being executed is stopped and an instruction to start the image data recording process after the cancel instruction is given.

  As described above, when the recording cancel switch 117 is pressed during the image data recording process and a recording cancel instruction is issued by the content erasing process as described above (step S21), the erasing process is performed every recording cycle, and the recording standby time is reached. The image data recorded in the previous recording cycle before the first recording cancel instruction is erased from the image data recorded on the disk 113 (step S32). On the other hand, image data recording processing is performed on input image data after the recording cancel instruction.

  Accordingly, the image data recorded on the disk 113 from the start of the image data recording process to the time of the first recording cancel instruction is the recording cycle before and the latest recording cycle before the first recording cancel instruction. Thus, the image data recorded in the same number of recording cycles as the number of times the recording cancel switch 117 is pressed is erased, and then the input image data after the first recording cancel instruction is recorded. .

  As described above, according to the video camera 100 of the present embodiment, when the recording cancel switch 117 is pressed during the image data recording process and a cancel instruction is given, the content erasing process is executed, and the first cancel instruction At each recording cycle immediately after the recording time, during the recording standby time, the image data recorded in the recording cycle before and immediately before the first recording cancel instruction is erased from the recording image data on the disk 113 and the first time Since the input image data after the cancel instruction is continuously recorded on the disk 113, the user presses the recording cancel switch 117, and the image data recording process is continued, and the disk is immediately before that according to the number of times of pressing. 113 deletes a predetermined amount of image data recorded in the image data. Can.

  Therefore, even when the recording capacity of the disk 113 decreases during shooting, the user adjusts the number of times the recording cancel switch 117 is pressed to adjust the desired capacity of the image data recorded on the disk 113 until just before that. By erasing the image data, the recording capacity can be secured without exchanging the disk 113. As a result, the user can continue shooting without missing a shooting opportunity, and can perform comfortable shooting.
