Summary:1. Field of the Invention An image block is detected by raster scanning an input image and chasing surrounding black pixels around a detected black pixel as the start point in sequence. Further, by judging the feature of the detected image block, the attribute of the image block can be judged. Also, by comparing the detected image block with a predetermined window, it is possible to determine whether or not the image block is noise, whereby image processing of higher accuracy can be effected.
