摘要

PROBLEM TO BE SOLVED: To provide the method for applying aliasing elimination to a segment of an image in a system that processes a document image including both a text/line drawing area and an image area. SOLUTION: The method includes a step where a document image is received, a step where an aliasing elimination filter 100 is applied to a text/line drawing area in the image so as to correct the image by a method of suppressing an action of aliasing, a step where pixels corrected by the aliasing elimination filter 100 are identified at the same time, and a step where the identified pixels are displayed in a way that this display is detected by succeeding processing operations.
