IMAGE PROCESSING APPARATUS WHICH PERFORMS ANTI-ALIASING ON INPUT IMAGE DATA AND IMAGE PROCESSING METHOD THEREOF

摘要

Disclosed in an image processing apparatus for performing anti-aliasing on input image data including a viewing window setting section which sets a viewing window of a predetermined size which includes a focused pixel, a difference determination section which extracts a plurality of combinations of two predetermined adjacent pixels in the viewing window and determines a difference between input pixel values of the two extracted pixels for each combination, a determination information obtaining section which obtains combination determination information based on a combination of determination results, and a pixel value calculation section which obtains an output pixel value of the focused pixel by carrying out a weighted addition of an input pixel value of the focused pixel and an input pixel value of a predetermined neighboring pixel which is adjacent to the focused pixel based on the combination determination information.
