ABSTRACT:
In a color input scanner for deriving digital signals from a full-color original image, a sensor bar having three parallel arrays of photosensors, each array being sensitive to a different primary color, is moved relative to the original image in a scan direction. With each scan cycle, the exposure of the photosensors in each array is precisely timed so that the optical "center of gravity" for each exposed area in the original image is superimposed for all of the primary color photosensors.
