ABSTRACT:
The image processing apparatus extracts edge pixels of an input image, connects the edge pixels so as to extract a segment, extracts an inclination angle of the image based on the segment, corrects an inclination of the image based on the angle, determines that correction has ended when the corrected inclination is equal to or less than a predetermined threshold value, and repeats inclination extraction, inclination correction and end determination using an output image obtained after the inclination correction as a new input image until it is determined that correction has ended.
