Description

  The present invention relates to a recording apparatus.

  2. Description of the Related Art Conventionally, a disc video camera that captures an image and records it on an optical disc such as a DVD is known. In a disc video camera, portability is emphasized, and it is proposed to use a small disc having a diameter of 8 cm instead of a general DVD having a diameter of 12 cm.

  By using a small disc, the size of the video camera can be reduced, and portability can be improved. However, a small disc has a smaller recordable capacity than a normal size disc. Therefore, for example, when traveling, shooting is performed on several discs.

  In this way, when an image recorded over a plurality of discs is reproduced, it is necessary to exchange and reproduce the disc each time.

In view of this, a system has been considered in which images taken on a plurality of disks with a video camera are copied and viewed on a home disk recorder equipped with a PC or a large-capacity HDD (for example, see Patent Document 1).

Reference numeral 105 denotes an input / output unit that inputs / outputs image signals to / from devices outside the apparatus, 106 denotes a control unit that controls each unit, 107 denotes an operation unit including various switches, keys, and the like, and 108 denotes group management information described later. Is a memory for storing. A recording / reproducing unit 109 records and reproduces data by irradiating the disk D with a laser beam, and 110 is a data bus. In this embodiment, an optical disk such as a DVD is used as the disk D.

  In FIG. 1, during normal shooting, moving image data obtained by the imaging unit 101 is sent to the encoding / decoding unit 102 and encoded according to the MPEG2 system. The encoded image data is sent to the recording / reproducing unit 109, and the recording / reproducing unit 109 records the encoded image data on the disk D. At the time of shooting, the display control unit 103 multiplexes various information in addition to the moving image obtained by the imaging unit 101 and displays the information on the display unit 104.

  At the time of reproduction, the image data recorded on the disk D is reproduced by the recording / reproducing unit 109 and sent to the encoding / decoding unit 102. The encoding / decoding unit 102 decodes the reproduced image data and sends the decoded image data to the display control unit 103. The display control unit 103 displays the decoded image on the display unit 104.

  The video camera 100 of this embodiment can manage a plurality of disks D as one group.

  In the following, the group management operation associated with the loading of a disk by the control unit 106 will be described with reference to the flowchart of FIG.

  When the disk D is newly installed, the flow of FIG. 2 starts. The flow in FIG. 2 is performed subsequent to the management information reading accompanying the loading of the disk D and the recording laser power adjustment processing.

  First, the management information is reproduced from the loaded disk D by the recording / reproducing unit 109 and stored in the memory 108. Here, the management information is information including information such as the content and recording position of data recorded on each disc, the file name, the remaining capacity of the disc, and the ID unique to the disc. In this embodiment, management information is reproduced and stored in the memory 108 when the disc is loaded, and the contents of the management information are updated according to the recording / reproducing operation for the disc D. Then, management information is recorded on a predetermined track on the disc when the disc is ejected.

  When the management information is read, the disk-specific ID included in the management information is detected (S202). Then, the disk ID is compared with the disk ID registered in the group information stored in the memory 108.

  In the present embodiment, group information for managing a plurality of disks classified into groups is generated and stored in the memory 108. This group information includes information such as the group name, the number of registered disks and the disk ID of each disk, and the total recording time of the group. The group information stored in the memory 108 is retained even when the video camera 100 is turned off.

  Here, the disk ID registered in each group is compared with the disk ID detected in S202, and it is determined whether or not to register in the group (S203).

  If registered, the process advances to step S208 to display the registered group information on the display unit 104. An example of the screen displayed in S208 is shown as 303 in FIG. Here, the registered group name and the number of disks in the group are displayed.

  On the other hand, if it is not registered in any group in S203, information for inquiring whether or not to register this disk in the group is displayed on the display unit 104 (S204). An example of the display screen at this time is shown at 301 in FIG.

  The user can select whether or not to register by moving the cursor 301A by operating the operation unit 107 (S205).

  If NO is selected here, the process proceeds to S209 to enter a recording standby state.

  When registration is selected, a screen indicated by 302 in FIG. 3 is displayed on the display unit 104, and the selection of a group to be registered is awaited. The user can select the group to be registered by moving the cursor 302A by operating the operation unit 107. 302 indicates that two groups with group names of group 1 and group 2 have already been registered. If the user wants to register as a new group different from any group, the user selects a new group (S206).

  When a new group is selected, group information relating to this new group is generated and stored in the memory 108. At this time, a default group name may be added to the group name, or a screen for inputting the group name may be displayed on the display unit 104, and the user may input the group name using the operation unit 107.

  When an existing group is selected, the ID of this disk is registered in the group information of the selected group among the group information stored in the memory 108 (S207). Then, the process proceeds to S208 to display the registered group information, and then enters a recording standby state (S209).

An example of the display screen of the display unit 104 in the recording standby state and the recording state is shown in FIG.
In FIG. 4, reference numeral 402 denotes the current recording time of the disc. Reference numeral 403 indicates the total recording time, group name, and disk number in the group in which the disk is registered.

  The control unit 106 displays information 03 based on the group information recorded in the memory 108.

  Thus, by displaying the total recording time of the group in which the current disk is registered, the total recording time of a plurality of disks registered in the same group can be easily recognized.

  For this reason, when the contents of the plurality of discs are collectively copied to one disc, time management is facilitated.

  In addition, on the screen 302 of FIG. 3, not only the group name but also the information of the total recording time of each group may be displayed together. Alternatively, the first scene image recorded on the first disk of each group may be reduced, stored in the memory 108 together with the group management information as representative image data representing the group, and displayed on the screen 302.

Some disc video cameras are configured so that a plurality of data rates of image data to be recorded can be set, and the user can arbitrarily switch the data rate.
In this case, the data amount is different even in the same recording time.

  Therefore, as the group information, in addition to the total recording time, the total data amount may be recorded, and the information on the total data amount may be displayed during shooting standby or during shooting.

An example of the display screen at this time is shown in FIG.
In FIG. 5, 501 is a display screen, 502 is information on the amount of data recorded on the currently loaded disc, and 503 is information on the total recorded data amount of this group of discs.
