ABSTRACT:
The disclosed a number of methods for scanning and individually detecting a number of images on a scanner platen. In one method, the scanner scans the platen one scanline after another and performs the following steps for each scanline. The method first detects and groups together one or more consecutive pixels of a current scanline having substantially similar colors (804,808,806). The method then determines (826) those said groups of pixels of a current scanline which likely belong to images and those which likely belong to background of the scanner. The method then copies (708) the determined groups of pixels belonging to images of a current scanline to their respective images.
