Abstract

PURPOSE:To preclude the possibility of mis-recognition of rear left and right sides by changing the direction of a video camera in interlocking with a speed changer of an automobile to facilitate the grasp of the rear part of the automobile approaching an obstacle at the back drive. CONSTITUTION:The video camera 11 is installed backward at the rear part of the automobile. A picture signal obtained by the video camera 11 is converted a picture signal whose left/right image is inverted by a picture left/right inverting circuit 12 and displayed on a display panel of a display device 13 provided near a driver's seat. The video camera 11 is directed as shown by an alternate long and short dash line in the normal state, and the speed changer 14 is pronght to the backward position R, a camera directing variable mechanism 15 is operated and the video camera 11 is directed as shown by an alternate long and two short dashes line. Since the video camera is directed toward the ground close to the rear part of the automobile at the backward drive, the grasp of the rear part of the automobile approaching an obstacle is facilitated.

れがあり極めて危険である。It is necessary to point the video camera at the ground near the exit of the car. On the other hand, if you drive the car forward at high speed in this state, only the ground near the rear of the car will be displayed.
It is difficult to grasp the driving conditions of the vehicle, especially those behind the vehicle. Furthermore, if the image signal obtained by the video camera is displayed directly on a display device, unlike the rear view shown in a normal rearview mirror, a left-right reversed image will be obtained, causing the driver to misunderstand the left and right conditions. This is extremely dangerous.

It is. The gear (2) of the video camera α is fixed and rotates about the shaft (c) in the opposite direction to the rotational direction of the camera.A worm gear (c) is engaged with the gear G!4, and the motor (To) rotates this worm gear (C). The gear Q4) rotates in a range between a position 82 on the upper side and a position 83 on the lower side.

後方を撮影する状態となっている。The gear (to) rotates counterclockwise, and the lower side becomes 83. In this state, only the switch (SW3) is turned on, so the two-man power of the NAND circuit C33 becomes H and L, and H and H, that is, no driving voltage is applied to the motor (M).
Rotation of gear Q4 is stopped. The video camera αυ is in the state of photographing a distant rear view.

Since the NAND circuit c (3) is 2 manual beams, L or HI, the output of this NAND circuit 0 is H. Therefore, a driving voltage opposite to that in the case of forward movement described above is applied to the motor (M). It is.

。The worm gear (C) rotates in the opposite direction to the arrow (E), and the gear (2) rotates clockwise. When the top side of the gear (2) reaches the state (S2), the switch (8W2) turns on. , the output of the NAND circuit (to) becomes H, and the rotation of the motor (80) and therefore the rotation of the gear (2) are stopped.In this way, the video camera αυ is moved from when moving forward, as shown in ■ in Figure @2. Also, you will be photographing the ground near the rear of the car.

ある。In the present invention, when the vehicle is not in reverse, the video camera can monitor the distant area behind the vehicle, and since the image signals obtained by the video camera are reversed left and right and displayed on the display device, conventional rearview mirrors cannot be used. You can see exactly the same way you look behind you. Therefore, there is no danger of misidentifying left and right as opposite while driving (safe driving is possible).
