ABSTRACT:
An image processing apparatus includes a contour extraction unit and a contour correcting unit. The contour extraction unit ascertains intensity difference between each of the pixels in the original image data and pixels around the pixel, and evaluates sharpness of a contour to determine intensity of a pixel in the contour image data based on gradient of intensity of the pixel. The contour correcting unit shifts a contour of the pixel in a predetermined direction based on a direction of a slant of the gradient of intensity when an absolute value of the gradient of intensity is larger than threshold.
