ABSTRACT:
A method and apparatus for automatic lateral alignment of front and rear images in a two sided scanning system. A line store is used for each camera to capture image data from a calibration target. A control processor then uses this image data to compute offset values which get stored for future use. The offset is then loaded into a hardware cropping circuit to correct the camera alignment in real time. Difficult manual alignment procedures are thus eliminated.
