ABSTRACT:
A color imaging device is comprised of means for sensing radiation comprising a planar array of charge-handling semiconductor photosensors, preferably at least one of the photosensors having a radiation sensing area with at least one dimension less than about 100 microns, and superimposed thereon, filter means for controlling access of radiation to the sensing means. The filter means is in micro-registration with the array of photosensors and comprises a transparent mordant layer with a plurality of radiation intercepting means defining a planar array of filter elements. The filter area of each intercepting means contains at least one mordantable dye which absorbs radiation in at least one portion of the spectrum and transmits radiation in at least one other portion of the spectrum. The color imaging device comprises an interlaid pattern having at least two sets of intercepting means, the first set having a different radiation absorption and transmission characteristic from that of the second set.
