<P>PROBLEM TO BE SOLVED: To sufficiently exhibit an effect of high-speed drawing by hardware drawing processing and the like without the occurrence of flicker due to a time difference of two kinds of the drawing processing by once performing the drawing processing for one field component or differential data component with a VRAM for drawing, and transferring the data to the VRAM for displaying which performs immediate reflection display to a monitor in the stage when the drawing processing is completed. <P>SOLUTION: The image display device 0200 has a VRAM 0201 for display which outputs the recorded drawing data in order to reflect the data immediately on the display screen, and a VRAM 0202 for drawing which creates the drawing data and transfers the data in a single field unit to the VRAM for display. Accordingly, the drawing processing for one field component by which the data etc., under drawing is not immediately reflected on the display screen is performed by the VRAM for drawing and the data can be transferred to the VRAM for display which performs immediate reflection display to the display screen in the stage when the drawing processing is completed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
