Abstract
Image reduction processing of a given original image is effected by determining the brightness of each picture element in a resultant reduced image in accordance with the numbers of black and white pixels in an intermediate matrix image obtained by quantizing the original image. When the black and white pixels in the quantized intermediate matrix image are equal, the aforesaid brightness is determined according to a prescribed criterion matrix pattern having a criterion point, thereby to obtain the reduced image on a display or the like with high fidelity to the original image.
