发明名称 Image processing method and apparatus
摘要 The present invention concerns an image processing method and apparatus especially having an intelligent function added to the image reading process to reduce the user's burden and extend significantly its utilization form, so that the processing efficiency or processing accuracy of image data can be enhanced. To this end, 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 its image block can be judged. Also, by comparing the detected image block with a predetermined window, it is possible to determine whether or not its image block is the noise, whereby the image processing of higher accuracy can be effected. <IMAGE>
