Patent ID: 7321446

Claim:
A color image processing device comprising: n line sensors which are arranged with a prescribed interval L between one another; an image signal output unit which outputs image signals under a prescribed cycle from the line sensors; a line memory which stores the image signals for a plurality of lines and outputs the image signals with a delay; and a control unit which controls to input one of the image signals of a certain cycle into the line memory, and to output an image signal from the line memory by delaying a certain number of lines, in accordance with a prescribed rate of magnification N, wherein when P is a pixel pitch in a sub scanning direction during a scanning operation under 100% magnification, the control unit calculates a number of pixels which increases and decreases by the rate of magnification from N·L/P, determines which cycle is to be selected in accordance with a decimal part d of the calculated number, and determines the number of delayed lines in accordance with an integral part D.
