Description

  The present invention relates to a vehicle periphery imaging apparatus that monitors the periphery of a vehicle with wirelessly transmitted video data.

  2. Description of the Related Art Conventionally, various vehicle periphery imaging devices that install an imaging camera in a vehicle and monitor the periphery of the vehicle have been proposed. For example, Patent Document 1 and Patent Document 2 disclose this. The vehicle periphery imaging device disclosed in Patent Document 2 uses an imaging camera that is detachable with a magnet, and is configured to wirelessly transmit video data captured by the imaging camera. There is no need for a cable for transmitting the image, and the imaging camera can be easily installed.

Japanese Patent No. 2901112 JP 2001-301538 A

However, since the imaging camera is detachable, the imaging camera may be stolen. That is, since the imaging camera installed in the vehicle can be removed without using any tools, there is a problem that the probability of being stolen is high.
The present invention has been made in view of this problem, and provides a vehicle periphery imaging device that can be easily attached and detached and has a function of suppressing theft.

  In order to solve the above-mentioned problem, the present invention captures the periphery of a vehicle in response to vibration and outputs image data, and image transmission for wirelessly transmitting the image data output from the image capturing unit 11 Means 13; video receiving means 21 for receiving the video data transmitted from the video transmitting means 13; video recording means 22 for recording the video data received by the video receiving means 21; Display switching means 24 for switching display between the video data from the means 21 and the video data from the video recording means 22.

  The present invention further includes vehicle operation determination means 23 for causing the video recording unit 22 to record the video data received by the video reception means 21 in accordance with the operating state of the vehicle.

  Theft can be suppressed by providing a function of transmitting imaging data by the imaging means according to vibrations expected at the time of theft and recording the imaging data.

The block diagram which shows embodiment of this invention. The flowchart which shows embodiment same as the above.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

The in-vehicle wireless camera 10 includes an imaging unit (imaging unit) 11, an operation detection unit 12, and a video transmission unit (video transmission unit) 13. The imaging unit 11 is a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide).
An image pickup device such as a semiconductor) is used to pick up an image of the periphery of the vehicle and output video data to the video transmitter 13. The motion detection unit 12 includes, for example, an acceleration sensor, and detects the vibration of the in-vehicle wireless camera 10. The video transmission unit 13 includes a wireless LAN and wirelessly transmits the video data output from the imaging unit 11.

  The receiving device 20 includes a video receiving unit (video receiving unit) 21, a video recording unit (video recording unit) 22, a vehicle operation determining unit (vehicle operation determining unit) 23, a display switching unit (display switching unit) 24, And a display unit 25. The video reception unit 21 receives the video data transmitted from the video transmission unit 13 and outputs the video data to the video recording unit 22 and the display switching unit 24. The video recording unit 22 includes a flash ROM, an HDD, or the like, and records the video data output from the video receiving unit 21.

  The vehicle operation determination unit 23 determines whether or not the vehicle is operating. The display switching unit 24 includes a switching switch such as a toggle switch or a push switch, or a software switch that switches display depending on the presence / absence of video recording that is not displayed on the video recording unit 22. The display unit 25 is made of, for example, a TFT liquid crystal display, and is installed at a position where the driver can see from the driver's seat.

  FIG. 2 is a flowchart from the start of operation of the in-vehicle wireless camera 10 to display of an image. First, when the motion detection unit 12 of the in-vehicle wireless camera 10 obtains a trigger for starting its own operation by vibration, the imaging unit 11 of the in-vehicle wireless camera 10 starts imaging (steps S1 and S2). Next, the video transmission unit 13 of the in-vehicle wireless camera 10 transmits the previously captured video data to the receiving device 20 (step S3).

  The video data transmitted by the video transmission unit 13 of the in-vehicle wireless camera 10 is received by the video reception unit 21 of the receiving device 20 (step S4). Next, it is determined by the vehicle operation determination unit 23 whether the vehicle is operating or not operating (step S5). If the vehicle is operating, the driver or passenger is present in or near the vehicle and records video data. Since it is not necessary, video data is not recorded. When the vehicle is not operating, there is a high possibility that no driver or passenger is present in the vehicle or in the vicinity of the vehicle. Therefore, when video data is transmitted from the in-vehicle wireless camera 10, the video recording unit 22 Data is recorded (step S6).

  The display switching state implemented in the display switching unit 24 is determined by a software operation such as a driver operation or a video recording state (step S7), and received from the in-vehicle wireless camera 10 in the received video display state. The video data is output to the display unit 25 and the received video is displayed (step S8). If the display switching unit 24 is in the recorded video display state, the video data recorded in the video recording unit 22 is output to the display unit 25 to display the recorded video (step S9).

  According to the present embodiment, the in-vehicle wireless camera 10 can determine the operation state by detecting its own operation, transmit video data, and the receiving device 20 can perform recording and display by performing vehicle operation determination. Thus, it is possible to identify a theft by adding a function for suppressing theft and recording video data at the time of theft.
