ABSTRACT:
When generating output image data represented by a reduced number of gray levels from gray level image data, an image processing apparatus subtracts a pixel value of a selected pixel from a pixel value of adjacent pixel, amplifies the reduced value obtained by the subtraction, adds the amplified value to a numerical value in a numerical matrix, and finds a pixel value in the output image data represented by a reduced number of gray levels of pixel values, based on a value obtained by further adding a value obtained by adding the amplified value to the numerical value in the numerical matrix to a predetermined value.
