Abstract

PURPOSE: To smoothly display animation pictures without rewriting graphic display data written in an overlay frame buffer.
CONSTITUTION: By making the capacity of an overlay frame buffer 3 larger than a display area of a one-screen portion, and also, changing a position of a display area 8 in the overlay frame buffer 3 by an overlay scan address generating circuit 6 independently of a main frame buffer 2, graphic display data written in the overlay frame buffer 5 can be moved smoothly by a scan timing on a screen of a CRT 1.
