Abstract:
A method of processing image data from a photosensitive imaging apparatus, the apparatus including a plurality of chips, each chip having a linear array of photosensors thereon, the photosensors on each chip being spaced by a predetermined pitch, each photosensor adapted to output a value related to light incident thereon, the chips being mounted with the linear arrays thereon arranged to form a main linear array, each pair of chips in the plurality of chips defining a gap therebetween, comprising the step of:for a chip, interpolating the outputs of the photosensors therein to effect a spatial displacement of the outputs along the main linear array, the displacement being a product of a constant and an integer, the integer relating to a position of the chip along the main linear array wherein the constant is related to a maximum pitch error between a pair of chips in the apparatus, the maximum pitch error being the largest pitch error whereby any corresponding image defects will remain invisible in recorded images made with the a apparatus.
