Description

  The present invention relates to an imaging / recording device, an imaging / recording method, a program storage medium, and a program, and in particular, when an instruction to start recording is input immediately after the recording medium is mounted, the imaging / recording process is started without a problem. The present invention relates to an imaging and recording apparatus, an imaging and recording method, a program storage medium, and a program.

  When video data and audio data are acquired (captured) using a video camera, there is a technique that uses a disk-shaped recording medium as a recording medium for recording the acquired video data and audio data (for example, Patent Document 1). .

JP-A-10-143777

  When recording of information on a disk-shaped recording medium such as a new magnetic disk, optical disk, or magneto-optical disk is started, formatting processing is executed prior to recording of information. The format process includes a physical format that is a process that physically sets the status so that data can be written to the recording medium, a table that manages the usage status of the disk area for the disk that has been physically formatted, and a hierarchy. There is a logical format (also called initialization) that prepares a directory portion representing a structure. Information cannot be written to a disc-shaped recording medium that has not been initialized.

  The format differs depending on the device used even when the same disc-shaped recording medium is used.

  Further, when the disc-shaped recording medium in which information is written is initialized, the recorded information cannot be read. Therefore, in an information processing apparatus (for example, a personal computer) in which a disk-shaped recording medium is mounted, the formatting process is not performed on all the disk-shaped recording media mounted, but based on a user operation input. , Display an operation window that can input an operation for instructing the start of the formatting process, notify the user of a message for confirming whether or not to format, and the user enters the operation window On the other hand, when an operation input for instructing execution of the formatting process is performed, the formatting process of the loaded disc-shaped recording medium is executed.

  For example, when an imaging recording device such as a video camera capable of recording information on a disk-shaped recording medium is used for coverage of news reports or sports broadcasting, it is desired to start imaging at the moment the cameraman holds the imaging recording device. There is a request.

  However, when the imaging recording apparatus is used for coverage of news reports or sports broadcasting, the disk-shaped recording medium used is often in a new state before formatting. Therefore, when the cameraman installs a disk-shaped recording device before formatting in the imaging recording device at the imaging site, a message for confirming whether or not to perform formatting is notified to the cameraman who is the user, and the cameraman displays the operation window On the other hand, when an operation input for instructing execution of the formatting process is performed, the formatting process of the loaded disc-shaped recording medium is executed. For this reason, it takes time until the imaging starts after the cameraman holds the imaging recording apparatus.

  On the other hand, if all the disk-shaped recording media loaded in the imaging recording apparatus are subjected to the formatting process, the disk-shaped recording medium on which information is recorded is erroneously loaded in the imaging recording apparatus. When this happens, the recorded information cannot be read.

  The present invention has been made in view of such a situation, and a recording medium before formatting is mounted on an imaging recording apparatus without erroneously performing formatting processing on a recording medium on which information has already been recorded.

It is possible to have a data capacity capable of storing a total of audio data to be stored.

  Based on whether the information is recorded in the information recording area of the recording medium, the information is recorded in the area where the information is recorded when the formatting process is performed on the recording medium by the format processing means. It is possible to determine whether or not the recording medium loaded in the recording apparatus has been formatted.

  According to the determination means, the recording medium mounted on the imaging recording apparatus is formatted based on whether information is recorded in an area where information of the defect management system of the recording medium is recorded. It can be made to determine whether or not

  The recording medium can be an optical disk.

Control Data 3 is a 32-cluster area for recording control information. DMA 3 is an area of 32 clusters used for the defect management system. Buffer 4 is an area of 32 clusters in which no information is recorded.

  Next, FIG. 9 is a diagram for explaining an example of the data structure of DMA1 to DMA4 in FIGS.

  In the recording film layer L1 and the recording film layer L0, DMA1 is a total area of 64 clusters, DMA2 is a total area of 64 clusters, DMA3 is a total area of 64 clusters, and DMA4 is In total, this is an area of 64 clusters.

  In each of DMA1 to DMA4, DMS (Defect Management Structure) is recorded. As shown in FIG. 9, the DMS includes a DDS (Disc Definition Structure) indicating defect structure information of the optical disc 123 and a DFL (Defect List) which is a defect list. DDS is recorded in the first four clusters of DMA1 to DMA4. Among the information described in the DDS, the information other than the information (First PSN of Defect List) indicating the first PSN (Physical Sector Number) of the DFL is the same in any of the DMA1 to DMA4. . The next four clusters of DMA1 to DMA4 are reserved areas, and the DFL is recorded first in the next eight clusters. However, as the information recording process proceeds (for example, the number of data rewrites increases, etc.), the reliability is gradually lost only with the 8-cluster DFL. The recording position is recorded in the DDS.

  In the case where the recording layer of the optical disk 123 is only one layer, for example, DMA1 to DMA4 are each an area of 32 clusters, and the first four clusters of DMA1 to DMA4 are DDS, followed by 4 Seven DFL areas are provided for each cluster. Therefore, when there is only one recording layer of the optical disc 123, the DFL is first described in the fifth to eighth clusters of DMA1 to DMA4. Then, since the reliability is gradually lost with only the four-cluster DFL recorded first, a valid DFL is recorded in the next four clusters, and the recording position is indicated in the DDS.

  The format determination unit 125 controls the pickup unit 122 to irradiate a predetermined area in the recording area of the optical disc 123 where information is recorded at the time of formatting, and receives a signal corresponding to the amount of reflected light received. To do. When the information is not described in the predetermined area, the format determination unit 125 cannot receive the RF signal. As a result, the format determination unit 125 can detect whether or not information is described in a predetermined area, and therefore determines whether or not the mounted optical disk 123 has been formatted based on the detection result. To do.

  The format determination unit 125 described with reference to FIG. 1 determines whether information is recorded in the DMA1 to DMA4 of the optical disk 123, in other words, the pickup unit 122 is in a recording area corresponding to the DMA1 to DMA4 of the optical disk 123. Whether or not the optical disk 123 has been formatted is determined based on whether or not an RF signal is supplied when the laser beam is irradiated.

  Further, even when the recording layer of the optical disc 123 is only one layer, the format determination unit 125 described with reference to FIG. 1 similarly determines whether information is recorded in the areas corresponding to DMA1 to DMA4. In other words, the optical disk 123 has been formatted based on whether or not an RF signal is supplied when the pickup unit 122 irradiates a laser beam to an area corresponding to DMA1 to DMA4 of the optical disk 123. It can be determined whether or not.

  Next, with reference to the flowchart of FIG. 10, processing that is executed when the imaging recording apparatus 11 has the optical disk 123 mounted and receives an imaging start command will be described.

  In step S1, the main control unit 101 determines whether or not a disk is loaded in the drive based on a signal supplied from a sensor provided in a drive (not shown). If it is determined in step S1 that a disk is not loaded, the process of step S1 is repeated until it is determined that a disk is loaded.

  If it is determined in step S1 that a disc has been loaded, the main control unit 101 enters a recording start instruction standby state in step S2, and if a recording start instruction is input from the input unit 104, each unit of the imaging unit 22 is set. Control is performed to cause each unit of the imaging unit 22 to start imaging and acquiring audio, and the captured video data and acquired audio data are temporarily stored in the buffer memory 117.

  Note that since the recording start instruction standby state is set in step S2, the imaging start instruction is input when the imaging start instruction is input during any of steps S3 to S7 described later, unlike the timing of step S2. At the same time, imaging processing is started by the imaging unit 22 controlled by the main control unit 101, and accumulation of captured video data and acquired audio data in the buffer memory 117 is started.

  Here, the storage capacity of the buffer memory 117 is determined at least in step S <b> 1 that the optical disk 123 is loaded, the loading motor is driven by a drive (not shown), and the optical disk 123 writes or reads data by the pickup unit 122. The amount of video data to be captured and the amount of audio data to be recorded is greater than or equal to the amount of video data to be recorded during the time from the loading to the position where the physical format and logical format are completed by the processing in step S7 described later. That is, the storage capacity that can be buffered in the buffer memory 117 is, for example, the loading time of the optical disc, the processing time of steps S3 to S7 described later, the resolution of the video data to be captured and the audio data to be recorded, and the captured image. It is determined by the compression method of the video data to be recorded and the audio data to be recorded.

  In step S <b> 3, the main control unit 101 determines whether or not the loaded disc is the corresponding optical disc 123.

  If it is determined in step S3 that the loaded disc is not the corresponding optical disc 123, in step S4, the main control unit 101 controls the drive control unit 124 to move a loading motor of a drive (not shown) in the eject direction. The disk is rotated, the loaded disc is ejected, the recording start instruction standby state is canceled, and the process is terminated.

  If it is determined in step S3 that the loaded disc is the corresponding optical disc 123, the main control unit 101 controls the drive control unit 124 in step S5, and the pickup unit 122 controls the recording area of the optical disc 123. Among them, a laser beam for reading information is irradiated to a predetermined position (for example, the above-described DMA1 to DMA4) where information is recorded at the time of formatting. The pickup unit 122 irradiates information reading laser light to a predetermined position in the recording area of the optical disk 123 where information is recorded, receives the reflected light, and a signal corresponding to the amount of reflected light Is supplied to the format determination unit 125. The format determination unit 125 checks the RF signal of the reflected light at a predetermined position in the recording area of the optical disc 123 where information is recorded during formatting.

  In step S <b> 6, the format determination unit 125 determines whether or not an RF signal component is included in the reflected light at a predetermined position where information is recorded during formatting, that is, the recording area of the optical disk 123. Among them, it is determined whether or not information is recorded at a predetermined position where information is recorded at the time of formatting.

  If it is determined in step S6 that the reflected light at the predetermined position does not include the RF signal component, in step S7, the format determination unit 125 does not include the RF signal component in the reflected light at the predetermined position. To the main control unit 101. The main control unit 101 instructs the format processing unit 126 to start a physical format and a logical format for the optical disc 123. The format processing unit 126 controls the pickup unit 122 to apply a physical format and a logical format to the optical disc 123, and the process proceeds to step S9 described later.

  If it is determined in step S6 that the reflected light at the predetermined position includes the RF signal component, in step S8, the format determination unit 125 includes the RF signal component in the reflected light at the predetermined position. To the main control unit 101. The main control unit 101 instructs the format processing unit 126 to confirm the file system. The format processing unit 126 controls the pickup unit 122 to read out predetermined control information for confirming the file system, determines whether or not the file system of the optical disk 123 is normal, and determines the determination result. Supply to the control unit 101.

  After the process of step S7 is completed, or when it is determined in step S8 that the file system of the optical disc 123 is normal, the main control unit 101 controls each part of the imaging unit 22 and the recording unit 23 in step S9. Then, the process of reading the data from the buffer memory 117 and sequentially recording the data on the optical disk 123 is executed, and the process ends.

  If it is determined in step S8 that the file system of the optical disk 123 is not normal, the main control unit 101 controls the output unit 105 in step S10, and the loaded optical disk 123 is controlled by text data or audio output. An error message indicating that the file system is not normal is notified to the user, the recording start instruction standby state is canceled, and the process ends.

  By such processing, even if the optical disc 123 on which information has already been recorded is loaded in the imaging recording device 11, the optical disc 123 before formatting is inserted in the imaging recording device 11 while preventing the format processing from being erroneously performed. Even if it is attached and the start of imaging is instructed immediately, the information captured together with the imaging start command can be recorded on the optical disc 123. Therefore, the user of the imaging recording apparatus 11 holds the imaging recording apparatus 11 in hand. At that moment, imaging can be started and information can be recorded without missing the timing.

  The series of processes described above can be realized by hardware, but can also be realized by software. When a series of processing is realized by software, a program constituting the software is installed in a computer, and the program is executed by the computer, whereby the above-described disc recording / reproducing apparatus 11 is functionally realized.
