Description

This invention relates to a vehicle video recording device, etc. Dashcams, which record vehicle status information before and after an accident (forward-facing video, vehicle speed, sudden acceleration/deceleration, etc.), provide valuable information for investigating accidents such as collisions. Therefore, their installation is becoming widespread, particularly in transport vehicles like trucks, and commercial vehicles like taxis and buses, and is also being installed in general vehicles. This dashcam is configured to record forward-facing video footage and driving data (braking, turn signal operation, driving route, etc.) for a certain period before and after an accident or sudden braking. To briefly explain the video data storage configuration, a CCD camera or similar device constantly captures images of the vehicle and its surroundings from the driver's viewpoint (field of view), and stores the captured images in a temporary memory such as a ring buffer. The images stored in this temporary memory are continuously updated with the latest images, and past video data is retained for a set period of time. On the other hand, a dashcam is equipped with sensors such as acceleration sensors that detect impacts occurring during accidents, sudden braking, or sudden steering. When the output value of these sensors exceeds a threshold, it reads video footage from a certain period prior to the threshold exceedance (impact detection) from temporary memory and stores it in non-volatile memory (such as an SD memory card). Furthermore, after the threshold is exceeded, it stores video footage captured by a CCD camera, etc., either directly into the non-volatile memory or via temporary memory. Thus, it has the function of saving video footage and driving data for a predetermined period before and after the impact, along with the aforementioned data, to the non-volatile memory (SD card). Furthermore, in the event of an accident, the system makes it possible to clearly prove the driver's innocence based on vehicle status information (such as video footage) stored in non-volatile memory. This type of drive recorder is disclosed, for example, in Patent Document 1. Japanese Patent Publication No. 2006-321423 This is a block diagram showing the configuration of a drive recorder, which is a preferred embodiment of the present invention.This diagram shows the connection relationship between the main unit and various parts of the dashcam.This is a perspective view showing the front and back of the main unit of the dashcam.This diagram shows how to insert a memory card into the main unit and an example of how to install the main unit in a vehicle.This diagram shows the installation of the front view camera on the vehicle.This diagram shows an example of installing an additional camera and the camera configuration.This diagram shows the mounting status of the rearview camera on the vehicle and its field of view.This diagram shows the method of supplying power to the rearview camera.This diagram shows an example of the remote control configuration and its mounting location on the vehicle.This figure shows an example of what is displayed on a display device when the camera's image is shown.This figure shows an example of what is displayed on the display device during playback.This is an example of the playback screen display. Figures 1 to 9 show the configuration of a drive recorder as a vehicle video recording device, representing a preferred embodiment of the present invention. Figure 1 is a functional block diagram, and Figure 2 is a device configuration diagram. As shown in Figures 1 and 2, the system comprises a main unit 1 (hereinafter also referred to as the main body) equipped with a control unit 10, and a remote control 11, GPS unit 12, rear-view camera 13, additional camera 14, front-view camera 15, display device 16, built-in microphone 17, external microphone 18, memory card slot 19, acceleration sensor 20, and speaker 21 connected to the control unit 10 of the main unit 1. As shown in Figures 2 and 3(a), the front of the main unit 1 is equipped with an AV output terminal 16b for outputting video and audio signals to the display device 16, a microphone terminal 18b for inputting audio signals from an external microphone 18, an SD card slot 19b (corresponding to the memory card slot 19 in Figure 1), and a slide lever 19c for locking and securing the SD card 2 (see Figure 4(a)) when it is inserted into the SD card slot 19b. The slide lever 19c is for locking the SD card 2 when it is inserted. As shown in Figure 4(a), the slide lever 19c is moved to the left to insert the SD card 2 into the SD card slot 19b. When the slide lever 19c is released, it returns to its original position (Figure 4(a)), locking the SD card 2 in place. As shown in Figure 3(b), the rear surface of the main unit 1 (the surface facing the front) is equipped with a vehicle signal connection terminal 40b, a remote control connection terminal 11b, a GPS u
