ABSTRACT:
A film video player for sensing a color negative film image to produce color positive video signals includes a single frame charge coupled device (CCD) image sensor having an integral color filter array for producing color negative video signals when illuminated with a negative color image. The single frame CCD image sensor is flash illuminated with an image from the color negative film during the vertical retrace intervals of the video signals. Signal processing circuitry inverts and color corrects the signals produced by the sensor to produce color positive video signals. To reduce readout clock frequencies, the single frame image sensor is provided with a pair of parallel output registers. Even numbered columns of the array are read out via one of the registers, and odd numbered columns the other. Odd numbered columns are overlayed with green filter stripes and even numbered columns are overlayed with alternate red and blue stripes. The signals from the output register serving the odd numbered columns are demultiplexed by switching back and forth between two identical output amplifiers.
