Abstract
A luminance cumulative integrating method in image processes comprises the steps of: storing the positions of all of the unit regions constituting at least one block region to be detected as position information into a plurality of memory areas whose readout order has been predetermined in one direction; storing the luminances at the respective positions of an optical image as luminance information corresponding to the position information; sequentially outputting the position information from the plurality of memory areas; taking out the luminance information corresponding to the position information from the luminance information stored; adding the luminance information; and thereby obtaining the block luminance of at least one block region.
