Abstract
A video signal composing circuit and method for aligning scanned CCD's in an optical reading device in which plural scanned CCD's are arranged in a line parallel to a reading surface. Clock pulses are counted which correspond to the scanning of the CCD's and compared with values set by plural switch groups. The outputs of the comparison circuits are coupled through a logic circuit which combines and gates the individual video output signals from the CCD's to produce a composite video signal which is free of overlap in video signals between adjacent CCD's.
