Abstract:
A scanner system for reading a color original image, comprising:a scanner having only two linear sensors, the scanner including:only two linear sensors, each linear sensor including a plurality of solid state image sensing devices arranged to sense the color original image with a bidirectional sub-scanning operation in two opposite directions, and to output an image signal,control means for outputting a control signal for defining a respective predetermined sensing condition of each of said linear sensors, anda resolution selection device which selectively switches a read resolution of said scanner; andan information processing unit having color misregistration correction means for correcting, on the basis of the control signal output from said control means, a color misregistration between image signals sensed by said plurality of solid state image sensing devices of said two linear sensors;wherein the control signal output from said control means comprises a signal containing information of a sub-scanning direction of each of said two linear sensors and a signal representing a resolution set by said resolution selection device; andwherein said control means is made of a RISC (Reduced Instruction Set Computer).
