ABSTRACT:
An image processor (10) for use with an image sensor (12) is provided. The image sensor includes two output channels (14, 16) for producing video signals in the form of a clock signal carrier which is amplitude modulated by picture element signal levels sensed by the image sensor (12). A first filter (22) is connected to the image sensor (12) for removing the clock signal from the video signals produced by the image sensor which are produced on the first channel (14). A second filter (26) is connected to the image sensor (12) for receiving video signals from the second channel (16) for removing the clock signal from the video signals produced by the image sensor (12) produced on the second channel (16). The filtered video signals are combined in a multiplexer (40) to produce a single video signal.
