ABSTRACT:
An image processing method and system in which an original image is read line by line by means of a plurality of image sensors to produce image data segments corresponding to respective segments of a line read by each of the image sensors. The image data segments produced by the image sensors are processed to produce a second plurality of image data segments, which are subsequently subjected to a predetermined image processing operation. The second plurality of image data segments are combined, either before or after being subjected to image processing, into a line of image data for each original image line. The optical processing performed on the second plurality of image segments is typically magnification or minification, and is performed by storing the second plurality of image segments in a memory and controlling the clock and the address of the memory by means of selective magnification data stored in another memory, wherein the magnification data are selected in accordance with the desired magnification or minification.
