Abstract
An image processor for processing image signals corresponding to an original image including a character image region, a halftone image region, and a continuous tone image region. The image processor includes a generator of a first kind of image signals corresponding to the character image region, and of a second kind of image signals corresponding to the halftone image region and the continuous tone image region, according to the image signals; a processor of the first image signals; and a processor of the second image signals. The generator includes a converter to convert the image signals into binarized image signals, which express the image with a black pixel and a white pixel, according to the density level of respective pixels of the image; a recognition circuit that recognizes partial image regions, each of which has a predetermined number of pixels in the image, as black regions when more than a predetermined number of the black pixels exist in each of the partial image regions, so that the original image comprises at least one of the group of the black regions and the group of a non-black regions; and an estimation circuit of a continuous length of the black regions.
