ABSTRACT:
An image processing apparatus first forms an edge image of an input image using, for example, SOBEL operator, and performs a smoothing process on the formed edge image by using an average filter. Thereafter, the image processing apparatus calculates a difference between the edge image and the edge smoothed image, and binarizes the edge image based on the difference.
