摘要

An image processing apparatus comprises: a histogram calculation unit for calculating a histogram that is consonant with an input image; a binary threshold value calculation unit for calculating a binary threshold value, based on the histogram, with which a predetermined area in the input image is blurred; a binarizing unit for binarizing the input image using the binary threshold value; and a calculation unit for calculating the color of the predetermined area of the input image based on the results obtained by the binarizing unit.
