Description

  The present invention relates to a recording apparatus provided with recording / reproducing means for recording / reproducing information data to / from a first recording medium and a second recording medium, a control method therefor, and a program for causing a computer to execute the control method. And a computer-readable storage medium storing the program.

  2. Description of the Related Art Conventionally, there has been known a video camera capable of photographing a subject and recording a subject video signal on an optical disc and a semiconductor memory card (see, for example, Patent Document 1). In such a video camera, an optical disc has a higher recording rate than a semiconductor memory card, and in particular, a DVD or a Blu-ray disc has a larger recording capacity than a semiconductor memory card. It is common to record still images on a semiconductor memory card.

  It has also been proposed to copy (copy) or move and record (save) still image data recorded on a semiconductor memory card onto an optical disk.

  Here, there are several standards for optical discs used for recording, but the rewritable type such as DVD-RW that can rewrite the recorded information and the information recorded once such as DVD-R cannot be rewritten. In order to make it possible to reproduce data recorded on a recording medium in a recording mode (format) by a reproducing apparatus, a write end process called finalization (hereinafter referred to as “finalize”) is performed. Necessary. When this finalization is performed, recording information can no longer be recorded regardless of the remaining capacity of the optical disk. The write-once type is generally handled as a storage disk because finalization cannot be canceled.

  According to the present invention, the recording area for recording the information data (still image data) recorded on the first recording medium on the second recording medium is set, and the second recording is performed based on the recording area. Since the recording operation of the information data on the medium is controlled, a recording area for the still image data can be secured in the second recording medium, and the user can check the free space of the second recording medium. It is possible to record the moving image data without making it. As a result, the second recording medium can be used not only as a moving image data recording medium but also as a recording medium for storing still image data.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.

The image data is controlled to be recorded, and the mounted optical disk 107 is controlled to record still image data and moving image data based on the image signal captured by the image sensor 102.

  In the operation unit 109, when moving or copying still image data recorded on the semiconductor memory card 106 to the optical disk 107 and recording it, a selection for setting a recording area for recording the still image data is performed. A selection unit 1091 is provided.

  The system controller 108 includes a copy / move control unit 1081, a capacity monitoring unit 1082, a recording area setting unit 1083, a recordable time setting unit 1084, a capacity excess warning unit 1085, and a display / output control unit 1086. Is provided.

  The copy / move control unit 1081 controls the recording / reproduction control unit 105 to read (reproduce) still image data from the semiconductor memory card 106 and perform control when copying or moving the still image data to the optical disc 107. . In addition, when moving still image data from the semiconductor memory card 106 to the optical disc 107, the copy / move control unit 1081 reads the still image data from the semiconductor memory card 106 and erases the still image data. When copying still image data from 106 to the optical disc 107, the semiconductor memory card 106 is automatically initialized after copying the still image data to the optical disc 107.

  The capacity monitoring unit 1082 controls the recording / playback control unit 105 to detect the free capacity (additional recordable capacity) of the optical disc 107 that needs to be finalized, the storage capacity of the semiconductor memory card 106, or the free capacity of the optical disc 107. The capacity of the recording medium is monitored such as comparison with a recording area set by a recording area setting unit 1083 described later.

  The recording area setting unit 1083 sets a recording area when moving or copying still image data recorded on the semiconductor memory card 106 to the optical disk 107 for recording. Specifically, the recording area setting unit 1083 determines the storage capacity of the semiconductor memory card 106 detected by the capacity monitoring unit 1082 when the selection unit 1091 selects the setting for automatically setting the recording area. When the recording area is set in the optical disc 107 and a setting for arbitrarily setting the recording area by the user is selected by the selection unit 1091, the input value input via the operation unit 109 is recorded. The area is set in the optical disc 107.

Control when displaying and outputting to the unit 110 is performed.

  FIG. 2 shows a control method for setting processing of a recording area for recording (copying, moving) still image data recorded on the memory card 106 on the optical disk 107 in the image recording / reproducing apparatus according to the embodiment of the present invention. It is a flowchart. The processing in FIG. 2 is executed when the user instructs the recording area setting processing by operating the operation unit 109. FIG. 4 is a diagram showing a user interface for setting a recording area when recording still image data recorded on the semiconductor memory card 106 on the optical disc 107. Here, FIG. 2 shows a process when “automatically set” the recording area is selected as indicated by an arrow in the user interface of FIG. Note that the selection processing at this time is performed by the selection unit 1091.

  First, in step S201, the recording / reproduction control unit 105 determines whether or not the optical disc 107 is mounted on the image recording / reproducing apparatus 100. If it is determined that the optical disk 107 is not loaded as a result of this determination, the process waits in step S201 until it is determined that the optical disk 107 is loaded. On the other hand, if it is determined in step S201 that the optical disc 107 is loaded, the process proceeds to step S202.

  In step S202, the capacity monitoring unit 1082 detects the free capacity of the optical disk 107 (additional recordable capacity in the case of an optical disk that requires finalization).

  In step S203, the recording / reproduction control unit 105 determines whether or not the semiconductor memory card 106 is attached to the image recording / reproducing apparatus 100. As a result of this determination, if it is determined that the semiconductor memory card 106 is not attached, the process waits in step S203 until it is determined that the semiconductor memory card 106 is attached. On the other hand, if it is determined in step S203 that the semiconductor memory card 106 is attached, the process proceeds to step S204.

  In step S204, the capacity monitoring unit 1082 detects the storage capacity of the semiconductor memory card 106.

  Subsequently, in step S205, the recording area setting unit 1083 automatically sets the recording area of the optical disc 107 according to the setting mode selected by the selection unit 1091 (in the setting screen of FIG. It is determined whether the mode is “Yes” mode. As a result of the determination, if it is determined that the mode is to automatically set the recording area of the optical disc 107, the process proceeds to step S206. On the other hand, if it is determined in step S205 that the mode is not a mode for automatically setting the recording area of the optical disc 107, the processing in the flowchart is terminated.

  In step S206, the recording area setting unit 1083 sets the storage capacity of the semiconductor memory card 106 detected in step S204 as a recording area to be secured in the optical disc 107.

  Subsequently, in step S207, the capacity monitoring unit 1082 detects the free space of the optical disc 107 detected in step S202 and the recording area set in the recording area setting unit 1083 (in this example, the semiconductor memory card 106 detected in step S204). The storage capacity is compared, and it is determined whether or not the free capacity of the optical disk 107 is larger than the recording area set by the recording area setting unit 1083. That is, in this step S207, it is determined whether or not the recording area set in step S206 can be secured in the optical disc 107.

  When it is determined in step S207 that the free space of the optical disk 107 is larger than the recording area set by the recording area setting unit 1083, that is, the recording area set in step S206 can be secured in the optical disk 107. Subsequently, in step S208, the recordable time setting unit 1084 calculates the recordable capacity of the moving image data by subtracting the capacity of the recording area set in step S206 from the free capacity of the optical disc optical disk 107 detected in step S202. Then, the recordable time of the moving image data in the recordable capacity is set. Here, FIG. 7 shows the display of “moving image recordable time” 701 as the recordable time of moving image data on the optical disc 107 when the camera screen is normally displayed after the setting of the recording area in the optical disc 107 is completed. 6 is a diagram showing a display example of a “still image recording area” 702 as a recordable area of still image data stored in a semiconductor memory card. FIG. After the processing in step S208 is completed, the display / output control unit 1086 causes the display / output unit 110 to display “moving image recording time” 701 and “still image recording area” 702 on the optical disc 107 as shown in FIG. After the output is displayed, the process in the flowchart ends.

  As a result of the determination in step S207, it is determined that the free space of the optical disk 107 is smaller than the recording area set by the recording area setting unit 1083, that is, the recording area set in step S206 cannot be secured in the optical disk 107. Subsequently, in step S209, the capacity excess warning unit 1085 outputs a message to that effect to the display / output unit 110 via the display / output control unit 1086 to warn the user. Thereafter, the processing in the flowchart is terminated.

  Thus, after securing a recording area for the memory card 106 on the optical disk 107, the system controller 108 monitors the recordable capacity of the optical disk 107 excluding the secured recording area during recording of moving image data on the optical disk 107. When the remaining recordable amount runs out, recording is stopped.

  FIG. 3 is a flowchart showing a control method of the image recording / reproducing apparatus according to the embodiment of the present invention. Here, FIG. 3 shows processing when “set to an arbitrary capacity” is selected for the recording area in the user interface of FIG. 4. Note that the selection processing at this time is performed by the selection unit 1091.

  First, in step S301, the recording / reproduction control unit 105 determines whether or not the optical disc 107 is mounted on the image recording / reproducing apparatus 100. As a result of this determination, if it is determined that the optical disc 107 is not loaded, the process waits in step S301 until it is determined that the optical disc 107 is loaded. On the other hand, if it is determined in step S301 that the optical disc 107 is loaded, the process proceeds to step S302.

  In step S302, the capacity monitoring unit 1082 detects the free capacity of the optical disk 107 (additional recordable capacity in the case of an optical disk that requires finalization).

  Subsequently, in step S303, the recording / reproduction control unit 105 determines whether or not the semiconductor memory card 106 is attached to the image recording / reproducing apparatus 100. As a result of this determination, if it is determined that the semiconductor memory card 106 is not attached, the process waits in step S303 until it is determined that the semiconductor memory card 106 is attached. On the other hand, if it is determined in step S303 that the semiconductor memory card 106 is attached, the process proceeds to step S304.

  Subsequently, in step S304, the capacity monitoring unit 1082 detects the storage capacity of the semiconductor memory card 106.

  Subsequently, in step S305, in the recording area setting unit 1083, the setting mode selected by the selection unit 1091 is a mode in which the user arbitrarily sets the recording area of the optical disc 107 (in the setting screen of FIG. It is determined whether or not the “mode” is set. As a result of the determination, if it is determined that the user arbitrarily sets the recording area of the optical disc 107, the process proceeds to step S306. On the other hand, as a result of the determination in step S305, when it is determined that the recording area of the optical disc 107 is not in a mode in which the user arbitrarily sets, the processing in the flowchart ends.

  In step S306, the recording area setting unit 1083 detects an input value related to the recording area input by the user, and sets the input value as a recording area to be secured in the optical disc 107. Here, FIG. 5 and FIG. 6 are diagrams showing an input screen by the user for setting the recording area. 6 shows that the user operates the “▲” key (increase) in the figure to increase the recording area to be secured in the optical disc 107 from the input value 10 MB to the input value 11 MB. Shows the case. The “▲” key (increase) and the “▼” key (decrease) are controlled by the operation unit 109.

  Subsequently, in step S307, the capacity monitoring unit 1082 detects the free space of the optical disc 107 detected in step S302 and the recording area set in the recording area setting unit 1083 (in this example, the user input value detected in step S306). And whether or not the free space of the optical disc 107 is larger than the recording area set by the recording area setting unit 1083 is determined. That is, in this step S307, it is determined whether or not the recording area set in step S306 can be secured in the optical disc 107.

  As a result of the determination in step S307, it is determined that the free space of the optical disk 107 is larger than the recording area set by the recording area setting unit 1083, that is, the recording area set in step S306 can be secured in the optical disk 107. Subsequently, in step S308, the recordable time setting unit 1084 calculates the recordable capacity of the moving image data by subtracting the capacity of the recording area set in step S306 from the free capacity of the optical disc optical disk 107 detected in step S302. Then, the recordable time of the moving image data in the recordable capacity is set. Thereafter, as shown in FIG. 7, the display / output control unit 1086 can record “moving image recordable time” 701 as the recordable time of moving image data on the optical disc 107 and still image data stored in the semiconductor memory card. After the “still image recording area” 702 is output and displayed on the display / output unit 110 as a special area, the processing in the flowchart ends.

  As a result of the determination in step S307, it is determined that the free space of the optical disk 107 is smaller than the recording area set by the recording area setting unit 1083, that is, the recording area set in step S306 cannot be secured in the optical disk 107. Subsequently, in step S309, the capacity excess warning unit 1085 outputs a message to that effect to the display / output unit 110 via the display / output control unit 1086 to warn the user. Thereafter, the processing in the flowchart is terminated.

  According to the present embodiment, the capacity monitoring unit 1082 detects the free capacity of the optical disc (second recording medium) 107 for recording / reproducing still image data and moving image data (steps S202 and S302), and a semiconductor memory card. (Recording area setting unit 1083 sets a recording area when moving or copying still image data recorded on (first recording medium) 106 to optical disk 107 and records it (steps S206 and S306), and sets a recordable time. The unit 1084 sets the recordable time of the moving image data on the optical disc 107 based on the free capacity of the optical disc 107 detected by the capacity monitoring unit 1082 and the recording area set by the recording area setting unit 1083 ( Steps S208 and S308), a still image data recording area is secured in the optical disc 107. Preparative it is, the user can perform recording of moving image data without having to worry about the free capacity of the optical disc 107. As a result, the optical disk 107 can be used not only as a recording medium for moving image data but also as a recording medium for storing still image data.

  In this embodiment, the case of recording and reproducing moving image data and still image data with respect to an optical disc and a semiconductor memory card has been described. However, instead of other optical discs and memory cards, other recording media are used. It is also possible to record / reproduce other information data in place of moving image data and still image data.
