Abstract

There is disclosed an image processing apparatus capable of smoothing the image in obtaining a binary image, by eliminating notches through comparison of the input image data with certain notch image patterns stored in the apparatus in advance. In order to maintain an effect of smoothing even when the resolution of the input image data is increased, the image patterns employed for the above-mentioned comparison are varied according to the resolution of the input image data.
