ABSTRACT:
A line sensor with photosites accurately located for color scanning. The sensor includes a plurality of photosites arranged in a two-dimensional, staggered pattern which is repeated across the length of the sensor. Only one photosite is located for every direction perpendicular to the axis of the line image. Individual color filters extend over all the photosites located at the same perpendicular distance from the line image axis. In one embodiment, the filters are disposed on separate transparent members which are aligned and assembled over the photosites.
