Abstract
In an image processing apparatus, first peak density pixels of one dimension each having a peak density in one-dimension direction larger than a predetermined density are detected from image data located in a predetermined image area of a document image, and second peak density pixels of two dimensions each having peak densities in two-dimension directions larger than the predetermined density are detected from the image data. Further, there are counted a number of the detected first peak density pixels of one dimension and a number of the detected second peak density pixels of two dimensions, and then, it is judged whether or not the image data located in the predetermined image area are image data of a dot photograph image, a photograph image or a character image based on the counted numbers.
