Abstract

PURPOSE: To shorten the processing time and take countermeasures against jaggedness by performing compression into the luminance level and luminance variation information on representative pixels and writing them, and reproducing the information and conducting luminance modulation. CONSTITUTION: Segment pixel data 10 after being compressed by a data compression part 2 are written in a frame memory 3. Namely, the data are compressed into the luminance levels of only the representative pixels and the number of pixels on an X including the representative pixels and information on luminance variation on the axis are generated so as to perform complete reproduction; and they are stored as compressed segment data 11 in the frame memory 3. Therefore, the amount of data stored in the frame memory 3 is made much less than that when the luminance levels of all pixels are stored. Consequently, the processing time is greatly shortened and reproduced segment data 14 similar to the original segment pixel data 10 can be restored by a data reproduction part 4 as a following stage, so an easy-to-see image after jaggedness countermeasures are taken can be displayed.
