Document Type and Number:
Japanese Patent JP2657010
Kind Code:
B2
Abstract:
PURPOSE:To perform the drawing and multi-window processing of a three- dimensional image at a high speed by providing a two-dimensional frame memory between a three-dimensional frame memory and a display. CONSTITUTION:A drawing information generation part 1 generates three- dimensional drawing information, etc., and the output of this drawing information generation part 1 is supplied to the threedimensional frame memory part 2 and the two-dimensional frame memory part 5 as a display frame memory part. The three-dimensional frame memory part 2 outputs drawing data stored in plural frame memories 2b-1-2b-4 to the two-dimensional frame memory part 5 by a transfer control part 2c. The two-dimensional frame memory part 5 expands the two-dimensional drawing information from the drawing information generation part 1 on a two-dimensional frame memory 5b and also stores the three-dimensional drawing data from the three-dimensional frame memory 2 on the two-dimensional frame memory 5b. A display control part 5c supplies the data stored on the two-dimensional frame memory 5b to a display 6 in the form a color video.
