Vehicle monitoring apparatus with broadly and reliably rearward viewing
First Claim
1. A vehicle monitoring apparatus comprising:
- a car (1) having a rear video camera (CCD1) mounted on a rear portion (11) of the car (1), a right video camera (CCD2) mounted in a right-sideview mirror (13) of the car (1), and a left video camera (CCD3) mounted in a left-sideview mirror (14) of the car (1);
a television receiver (3) including an audio and video receiving circuit (30), a deflection circuit (31) and a sounding circuit (32) for receiving video signals from said video cameras (CCD1, CCD2, CCD3) and for receiving audio signals from a sound-signal sensor (5) mounted on the car (1);
a display means (7) having a cathode ray tube (CRT) therein and mounted in the car (1);
a mirror-effect circuit (4) connected to the deflection circuit (31) of the television receiver (3) for inverting two poles (H1, H2) of a pair of horizontal deflection coils (Hc) of the deflection circuit (31) for changing a left to right scanning direction to a right to left scanning direction for reproducing a picture on the cathode ray tube (CRT) of the display means (7) in response to a true subject positioned at a rear side of the car (1), thereby reversing a right-and-left picture orientation from the left-to-right scanning direction to have right-and-left orientation of the picture shown on the display means (7) to be same as that of the true subject at the rear side of the car (1) for safely driving the car (1) when backing or turning the car (1); and
a system control circuit (6) for controlling the actuation of the cameras (CCD1, CCD2, CCD3), the mirror-effect circuit (4) and the sound-signal sensor (5).

Abstract
A vehicle monitoring apparatus includes a rear video camera mounted on a rear portion of a vehicle, a right video camera mounted on a right sideview mirror, a left video camera mounted on a left-sideview mirror, a mirror-effect circuit connected across two poles of a pair of horizontal deflection coils of a horizontal deflection add oscillation circuit of a television receiver electrically connected to the video cameras for inverting an image or picture orientation to be the same as an orientation of the real subject positioned at a rear side of the vehicle, whereby upon a backing, a rightward turning or a leftward turning of the vehicle a corresponding video camera will be initiated to transmit a "picture" of the subject positioned at the rear side of the vehicle to display a picture on a television placed in the vehicle having a same orientation of the picture as that of the true subject for preventing an accidental collision due to falsely backing or turning of the vehicle for driving safety.
