ABSTRACT:
An optical scanning device is disclosed that generates data representative of a color image of an object using only one linear photosensor array. Image data corresponding to two or more color components is collected by making multiple incremental, reciprocal displacements of a scanning head with a different filter or other color selection mechanism in place during different incremental displacements. By traversing the scanned object in a series of reciprocal movements, color component data corresponding to relatively small portions of the scanned object is sequentially collected in and then removed from dynamic memory. As this data from each path segment is removed from dynamic memory, it is processed to place it in a correlated form representative of a polychromatic image of that path segment and is then stored in an ordered array in another, typically longer term, memory device such as a hard disk.
