Independent Claim
129 words
In apparatus to permit viewing of traffic or other conditions to the rear and side of a motor vehicle having opposite sides, and including a) video camera means mounted to the vehicle and directed sidewardly relative to the vehicle, and CRT means operatively connected to the camera means to display the camera means output on CRT screen means, to be viewed by the driver, the improvement, in combination with said apparatus, comprising: b) means for effecting swiveling of said camera means, and c) enhancement means associated with said video camera means to enhance viewing thereof to the rear and side of the vehicle, said enhancement means including i) dwell circuitry connected with said swiveling means to automatically effect stopping of said camera means swiveling during a predetermined dwell interval.
Claim 2
Dependent Claim
129 words
In apparatus to permit viewing of traffic or other conditions to the rear and side of a motor vehicle having opposite sides, and including a) video camera means mounted to the vehicle and directed sidewardly relative to the vehicle, and CRT means operatively connected to the camera means to display the camera means output on CRT screen means, to be viewed by the driver, the improvement, in combination with said apparatus, comprising: b) means for effecting swiveling of said camera means, and c) enhancement means associated with said video camera means to enhance viewing thereof to the rear and side of the vehicle, said enhancement means including i) dwell circuitry connected with said swiveling means to automatically effect stopping of said camera means swiveling during a predetermined dwell interval.
Claim 3
Dependent Claim
89 words
The combination of claim 1 wherein said video camera means includes a first video camera at one side of the vehicle and operatively connected with a first screen portion of said CRT means, and said enhancement means comprising a second video camera means at said one side of the vehicle, and operatively connected with a second screen portion of said CRT means, said first and second video cameras directed to view different zones at the side and rear of the vehicle relative to said one side of the vehicle.
Claim 4
Dependent Claim
56 words
