ABSTRACT:
An input scanner for converting original hard-copy images into digital signals is adapted for efficient scanning of simple "business color" documents. Three linear arrays of photosensors, each linear array corresponding to one primary color, are moved relative to the original image. One linear array of photosensors operates on a full cycle and converts every single scan line of the original image into digital signals. Simultaneously, the other primary-color-sensitive linear arrays operate on half cycles and record only signals corresponding to an evenly-distributed subset of small areas of the original image.
