ABSTRACT:
An image sensor is disclosed which is adapted to sense a color image and comprises three channels, one for each of the primary colors. Each channel is identical except for the color of the filter associated therewith. In order to provide the optimum exposure time for each of the colors, the integration time for each of the channels is controlled independently. The line readout time for each of the channels is maintained the same, however, so that the three channels can be read out in parallel.
