Abstract
A graphic processor including a rendering control circuit which carries out weighted averaging on pieces of pixel data of source image information arranged to form a pixel-data matrix corresponding to a pixel matrix with columns of the pixel-data matrix being oriented perpendicularly to a scanning direction in order to compute a weighted average of pieces of pixel data on rows of the pixel-data matrix adjacent to each other and on a column of the pixel-data matrix perpendicular to the scanning direction in so-called blend processing. The rendering control circuit reads out pieces of pixel data from the pixel-data matrix sequentially in a direction perpendicular to the scanning direction and computes a weighted average of the pieces of data. Image data subjected to blend processing is displayed by adopting an interlace scanning technique thereby eliminating undesired flicker.
