PHOTOSENSOR ARCHITECTURE FOR A COLOR RASTER INPUT SCANNER

In an image sensor array, as would be used in an input scanner such as in a digital copier, an original image is moved relative to a linear array of photosites. Each photosite includes at least two wide photosensors, each of which extends substantially across the photosite along the array direction, and at least two narrow photosensors, which are arranged next to each other along the array direction. In one embodiment, the wide photosensors include primary-color filters and the narrow photosensors are clear-filtered.
