Description

  The present invention relates to a recording apparatus.

  2. Description of the Related Art Conventionally, there are imaging apparatuses that can capture images of different recording formats by switching between a plurality of recording modes such as an SD mode and an HD mode.

In the control of a plurality of shooting modes of a conventional imaging apparatus, the shooting mode of the main body used at the time of shooting is stored, and the mode is preferentially selected at the next shooting so that the shooting operation can be performed more. There is a technology for making it comfortable (see Patent Document 1).
Unexamined

  However, such a technique is only a technique related to setting of the imaging apparatus main body, and is not related to a storage medium used in the imaging apparatus.

  For this reason, for example, when shooting is performed with an imaging device having a plurality of recording modes as described above, formatting is performed on one recording medium without noticing the setting change from the previous time due to the carelessness of the photographer. There is a possibility that a different recording medium is captured and a recording medium in which images of a plurality of recording formats are mixed is created. Also, when shooting with such an imaging device, in order to find out what the format of the image recorded last on the recording medium later is, insert the recording medium into some kind of playback device, and the last image shot There are methods such as searching for and trying to play it, but it takes a lot of work.

  The present invention is for solving such a problem, and prevents the recording media from being mixed in the recording medium of a single imaging apparatus, unifying the recording formats, and photographing. An object of the present invention is to make it possible to easily determine the recording format of the last recorded data in a recorded recording medium.

  The present invention provides a recording means for recording information data on a recording medium, a detecting means for detecting which one of a plurality of recording formats is a recording format of the information data recorded on the recording medium, Control means for matching the recording format of the information data recorded by the recording means with the recording format detected by the detecting means.

  According to the present invention, it is possible to standardize the recording format by preventing information data of different recording formats from being mixed in one recording medium.

  As an effective embodiment of the present invention, it is conceivable to apply to a digital video camera capable of photographing in a plurality of recording formats by switching the recording mode.

  Here, the recording format of a digital video camera is a standard relating to image recording classified by the number of pixels, aspect ratio, image compression method, etc., and a conventional example of a recording mode of a digital video camera according to this standard For example, there are DV mode, SD mode, and HD mode. FIG. 1 shows a configuration diagram of a digital video camera apparatus 100 in an embodiment of the present invention. An image sensor 101 such as a CCD converts the captured image of the subject into an electrical signal and outputs the electrical signal to the signal processing circuit 102. The signal processing circuit 102 processes the input signal and outputs it to the recording / reproducing circuit 103. The recording / reproducing circuit 103 outputs the input signal to the recording medium 108.

  Control control of each block is performed by the control circuit 104. Reference numeral 105 denotes operation buttons including a recording button 105a, a playback button 105b, a camera / playback switch 105c, a recording mode switching switch 105d, and the like. The digital video camera apparatus 100 can perform recording by switching the camera / playback switch 105c to the camera side and pressing the recording button 105a. At that time, the digital video camera apparatus 100 performs recording in a recording format corresponding to the recording mode currently selected from a plurality of recording modes such as DV mode, SD mode, and HD mode. The recording mode can be selected by switching the recording mode changeover switch 105d.

  The image being recorded is displayed on the CVF 106 or LCD 107. The user can selectively use one of these to confirm the image.

  When the LCD 107 is closed, the LCD switch is pushed in. At this time, the power of the LCD 107 is OFF, and the image is confirmed using the CVF 106. When the LCD 107 is open, the power of the LCD 107 is on, and an image is displayed on the LCD 107. At this time, no image is displayed on the CVF 106.

  When playing back a recorded image, the camera / playback switch 105c is switched to the playback side, and the playback button 105b is pressed to display the image on the CVF 106 or LCD 107. Also at this time, the user can selectively use either the CVF 106 or the LCD 107 as the display screen.

  As a first embodiment, a case where a tape is selected as the recording medium will be described.

  FIG. 2 shows a flowchart of the present invention. Hereinafter, the present invention will be described in detail according to this flowchart.

  First, when a tape is inserted into the digital video camera (S201), and the camera / playback switch of the main body is switched to the camera side (S202), the control circuit 104 records immediately before viewing from the current stop position of the tape 108. The recording format information of the current image is read (S203), and it is determined whether or not additional information relating to the recording format exists in the tape (S204). In general, with a digital video camera, when the camera / playback switch is switched to the camera side, the tape rewinds slightly from the end of the previous recording, and once the tape is in the playback state, the positional relationship of the tape is accurately determined. After starting up to a steady value, it stops just before the end of the recorded tape, and enters a standby state waiting for the recording button to be pressed. Reading of the recording format information is performed in the above-described playback state. If additional information relating to the recording format cannot be found at the time of detection, the recording mode of the digital video camera body becomes the mode currently selected by the recording mode changeover switch 105d (S209, FIG. 4). At this time, a message is displayed on the CVF 106 or LCD 107, “There is no format information .... Record in mode” (S210, FIG. 8).

  In addition, when the tape 108 is stopped near the joint between different images and a plurality of recording format information is detected at the time of detection, the recording format detected first is determined as the immediately preceding recording format. (FIG. 5).

  If there is additional information on the recording format in the tape 108 and the recording format in the current recording mode of the digital video camera body is different from the recording format of the tape 108 detected above, the recording circuit is switched from the control circuit 104. An electrical signal is sent to the switch 105d, and the recording mode changeover switch 105d is switched so that the recording mode of the main unit matches the detected recording format (S208). For example, if you insert a tape in which the previous image is recorded in the SD format into a digital video camera whose recording mode switch 105d is set to the HD mode, set the camera / playback switch on the digital video camera body. When set to the camera side, the recording mode changeover switch 105d of the main body is automatically switched from the HD mode to the SD mode side (FIG. 6). If the recording format of the digital video camera main body and the recording format of the tape 108 detected above are the same, the recording mode switch 105d is not switched (S209).

  The recording mode information at this time is displayed on the CVF 106 or LCD 107 with a message “Current recording mode is mode” (S210, FIG. 9). As a result, even if the user forgets the recording mode in which the user has forgotten the tape 108, the user inserts it into the digital video camera having the function of the present invention, and performs camera / playback. Just by setting the switch to the camera side, the recording format of the image immediately before the tape 108 can be known.

  After the message is displayed, recording can be performed by pressing the recording button 105a. At that time, additional information regarding the recording format is written on the tape 108 together with the image (S211).

  As a second embodiment, a case where a disk is selected as the recording medium will be described.

  Since the configuration diagram is the same as that of the first embodiment, a description thereof will be omitted. FIG. 3 shows a flowchart. Hereinafter, the present invention will be described in detail according to this flowchart.

  First, when a disc is inserted into the digital video camera body (301), the control circuit 104 reads the recording format information from the latest file on the disc (S302), and whether additional information relating to the recording format exists in the disc. It is determined whether or not (S303).

  Generally, when the recording medium of a digital video camera is a disc, the digital video camera body reads various information such as the remaining disc capacity and disc type when the disc is inserted.

  At this time, the recording format information is also read. If there is no recording format information in the disc, the recording mode of the digital video camera main body becomes the mode currently selected by the recording mode changeover switch 105d (S306). At this time, a message is displayed on the CVF 106 or LCD 107 "There is no format information .... Record in mode" (S307, Fig. 8).

  If the recording format information in the disc can be detected and the recording format in the current recording mode of the digital video camera is different from the recording format of the latest file in the disc, an electrical signal is sent from the control circuit 104 to the recording mode switch 105d. Is sent and the recording mode changeover switch 105d is switched so that the recording mode of the main unit matches the detected recording format (S305). For example, if you insert a disc in which the latest image file is recorded in DV format into a digital video camera whose recording mode switch 105d is in the HD mode side, the recording mode switch 105d on the main unit will Switch from HD mode to DV mode (Figure 7). If the recording format in the current recording mode of the digital video camera main body is the same as the recording format detected above, the recording mode changeover switch 105d is not automatically switched (S306).

  The recording mode information at this time is displayed on the CVF 106 or LCD 107 with the message “Current recording mode is mode” as in the first embodiment (S307, FIG. 9).

  After the message is displayed, recording can be performed by pressing the recording button 105a. At that time, additional information regarding the recording format is written on the disk 108 together with the image (S308).

  Compared with Example 1, Example 2 does not have to worry about problems such as tape joints, overwriting, and BLANK area, so the present invention can be applied more effectively.

  Further, the recording mode automatic switching function according to the present invention can be turned off from a menu or the like regardless of the first and second embodiments. Switching of the recording mode by the photographer at that time is performed by manually moving the recording mode switching switch 105d.
