Backup camera

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.

Abstract: Apparatus permits viewing of traffic or other conditions to the rear and side of a motor vehicle having opposite sides, and includes video camera structure mounted to the vehicle and directed sidewardly relative to the vehicle, and CRT structure operatively connected to the camera structure to display the camera output on a CRT screen zone or zones, to be viewed by the driver, and enhancement means is associated with the video camera structure to enhance viewing or scanning thereof, to the rear and side of the vehicle.

Abstract: A vehicular imaging and display system (10) includes a rear backup camera (12) at a rear portion of a vehicle (14), a video processor (18) for processing image data captured by the rear camera, and a video display screen (16) responsive to the video processor to display video images. During a reversing maneuver of the equipped vehicle, the video display screen displays video images captured by the rear camera. During forward travel of the equipped vehicle, the video display screen is operable to display images representative of a portion of the field of view of the rear camera to display images representative of an area sideward of the equipped vehicle responsive to at least one of (a) actuation of a turn signal indicator of the vehicle, (b) detection of a vehicle in a side lane adjacent to the equipped vehicle and (c) a lane departure warning system of the vehicle.

Abstract: An undistorted view of regions rearward of a vehicle such as a tractor-trailer is provided by a closed circuit television system wherein a television camera having a wide angle viewing capability is positioned at the rear of the vehicle at an effective viewing elevation between about 20% and 70% of the total height of the vehicle. The camera is protected against debilitating factors by a protective enclosure which occupies minimal space and affords secure attachment to said vehicle by virtue of a mounting wherein the axis of said camera lens is horizontally disposed in a plane perpendicular to the longitudinal axis of said vehicle. A mirror associated with said camera lens at a 45 degree angle thereto serves the two-fold purpose of permitting the desired mode of mounting of said enclosure, and reversing the image presented to said camera. The camera is connected by means of electrical wires to a television receiver positioned within easy view of the driver of the vehicle.
