Graphics processing system for deleting one of overlapping line and graphics images

摘要

A graphics processing system arranged to display on a display screen of a display unit a line image produced on the basis of image data stored in a storage and graphics produced on the basis of vector data stored in the storage in an overlapping manner contains a line image delete processing unit for implementing delete processing of the line image in a segment in which a pixel displaying the graphics is displayed so as to overlap with a pixel displaying the line image, wherein the line image delete processing unit is arranged so as to leave only the pixel displaying the graphics undeleted yet to delete the pixel displaying the line image within a range from a range which is broader than a predetermined line width of a distorted line to a line width of the line image.
