ABSTRACT:
An image sensing element in a solid state imaging device is provided with a plurality of superposed channels disposed at respective distances from a light receiving surface of the device, each of such channels having a different characteristic spectral response due to the differential absorption of light by a semiconductor. By so disposing the channels, the device becomes a color imaging sensor having optimized resolution. The top channel, i.e. the channel nearest the surface of the device, may be either a "surface" channel or a "buried" channel, the lower channel(s) being buried channels. Depending upon the design of the element, either electrons or holes may be accumulated as photocharges in respective superposed channels. The color photocharges generated in respective channels of such an image sensing element are simultaneously moved in a plurality of superposed channels by a multiple superposed channel signal handling device such as a multiple channel charge coupled device (CCD), thus the solid state imaging device does not require special timing networks to correct for phase differences between color signals which result from a common point within an image.
