ABSTRACT:
The invention intends to provide a display control apparatus which can perform the flickerless display at a high precision without changing a construction of the electrodes or the like of a display apparatus even when a display speed in the high precision display of a liquid crystal display apparatus is insufficient for the flickerless display in the non-interlace drawing. The display control apparatus 50 has a VRAM and a partial rewrite display control section. Since a WS (host computer) 1 prevents a flicker of the display in the animation image display, for an object which is drawn at a high speed, when image data stored in the VRAM is partially rewritten by the non-interlace, the partial rewrite display control section adds data indicative of the display position of the portion rewritten by the WS 1 to the image data and sync signal of such a rewritten portion and, after that, supplies the image data to a liquid crystal display apparatus 3 at the timing synchronized with the display to the CRT.
