It is configured to switch off in the event of a failure.

  The control unit 101 of the imaging apparatus 1 determines the on / off state of the switch SW at timing such as when the power is turned on. When it is determined that the switch SW is on, the control unit 101 determines that the mounting tool 2 for the vehicle is attached to the imaging device 1, and the imaging method and recording method for the drive recorder (hereinafter referred to as drive recorder mode). Select).

  On the other hand, if it is determined that the switch SW is off, the control unit 101 is mounted with another fixture that does not switch the switch SW on (for example, the fixture 3 that can be attached to the human body), or It is determined that the fixtures 2 to 4 are not attached to the imaging apparatus 1, and an imaging method and a recording method (hereinafter referred to as action cam mode) for the action cam are selected.

FIG. 6 is an explanatory diagram for explaining an example of an imaging method and a recording method that are selected in accordance with ON / OFF of the switch SW. When the switch SW is turned on (that is, when the drive recorder mode is selected), the control unit 101 has a frame rate of about 24 Hz to 29 Hz and a rate of about 4 Mbps in order to take measures for long-time recording, LED signal color fading, and the like. An imaging method is selected in which the bit rate, full HD (1920 × 1080) resolution, electronic image stabilization is turned off, and the angle of view is set to 130 degrees or more. In addition, as a recording method when the switch SW is on, the control unit 101 uses the timing when the power of the imaging device 1 is turned on as the recording start timing, and is protected when the capacity of the recording unit 107 becomes full. A recording method is selected in which overwrite recording is performed sequentially from an old file that does not exist, and the file is automatically divided at regular recording time intervals (for example, in units of several minutes).
It is assumed that setting information related to these imaging method and recording method is stored in the storage unit 102 in advance.

  In the present embodiment, the frame rate in the drive recorder mode is set to about 24 Hz to 29 Hz, but this is set to 25 Hz or 30 Hz synchronized with the power supply frequency 50 Hz or 60 Hz as a countermeasure against the color fading problem of the LED traffic light. It is because it is not preferable to do. In the present embodiment, when the drive recorder mode is selected, the frame rate is set to 24 Hz, for example, and when outputting, HDMI is output from the output unit 110 and video is displayed on the display device, and 3: 2 pull-down is performed. To 30 Hz or 60 Hz. In this embodiment, since the frame rate is set low, it is possible to contribute to the reduction of the bit rate.

On the other hand, when the switch SW is off (that is, when the action cam mode is selected), a frame rate of 60 Hz or higher, a bit rate of 15 Mbps or higher, a full HD resolution, and an electronic camera shake to cope with a fast movement of the subject. An imaging method is selected in which correction is turned on and the angle of view is set to about 100 degrees. In addition, as a recording method when the switch SW is OFF, the timing designated by the user is set as the recording start timing, the recording is automatically stopped when the capacity of the recording unit 107 becomes full, and the file is divided. Select a recording method that does not perform recording.
It is assumed that setting information related to these imaging method and recording method is stored in the storage unit 102 in advance.

  In this embodiment, the angle of view is changed according to the drive recorder mode or the action cam mode, but it has a wide-angle lens of 130 degrees or more, an effective imaging range of full HD or more, and can be read at high speed. When the imaging unit 103 includes an image sensor, it is possible to deal with the angle of view of both modes by software processing without preparing a hardware platform corresponding to each angle of view. In the case where the imaging unit 103 includes a zoom lens, the angle of view may be changed by changing the focal length of the zoom lens.

  FIG. 7 is a flowchart for explaining the operation procedure of the imaging apparatus 1. After the power of the imaging device 1 is turned on and the control unit 101 is reset, the control unit 101 determines whether or not the switch SW is on (step S101). The control unit 101 can determine on / off of the switch SW by a known method. For example, the control unit 101 may make a determination based on a signal input through GPIO. Alternatively, the controller 101 and the switch SW may be connected via a strap pin, and the on / off state of the switch SW may be determined by determining the pull-up and pull-up of the strap pin.

  If it is determined that the switch SW is on (S101: YES), the control unit 101 selects the drive recorder mode (step S102), and starts recording using the imaging method and recording method specified in the drive recorder mode. (Step S103). After starting the recording, the control unit 101 controls the recording / reproducing unit 106 so that the video data output from the imaging unit 103 and the sound data output from the signal processing unit 105 are recorded in a preset recording time. Recording is performed in the recording unit 107 at intervals.

  Next, the control unit 101 determines whether an operation for turning off the power of the imaging apparatus 1 is received through the power button provided in the operation unit 109 (step S104). When the operation to turn off the power is not accepted (S104: NO), the imaging device 1 continues recording.

  When an operation to turn off the power is accepted (S104: YES), the control unit 101 performs control to stop the recording (step S105), and the process according to this flowchart ends.

  If it is determined in step S101 that the switch is not on (S101: NO), the control unit 101 selects the action cam mode (step S106) and determines whether or not an operation for starting recording is accepted through the operation unit 109. (Step S107).

When the operation for starting the recording is not received (S107: NO), the control unit 101 stands by until the operation for starting the recording is received.
If it is determined that an operation to start recording is accepted (S107: YES), the control unit 101 starts recording using the imaging method and recording method specified in the action cam mode (step S108). After starting the recording, the control unit 101 controls the recording / reproducing unit 106 to cause the recording unit 107 to record the video data output from the imaging unit 103 and the sound data output from the signal processing unit 105.

  Next, the control unit 101 determines whether an operation for stopping recording is accepted through the operation unit 109 (step S109). When it is determined that the operation for stopping the recording is not accepted (S109: NO), the control unit 101 determines whether or not the capacity of the recording unit 107 is full (step S110).

  When the capacity of the recording unit 107 is not full (S110: NO), the control unit 101 performs control to continue recording. On the other hand, when it is determined in step S109 that an operation for stopping recording is accepted (S109: YES), or when it is determined in step S110 that the capacity of the recording unit 107 is full (S110: YES), the control unit 101 Control to stop the recording is performed (step S111), and the processing according to this flowchart ends.
