ABSTRACT:
A method of the present invention relates to a method of blending a plurality of pixels on a texture map and to a plural pixel blending circuit and image processing device using this is disclosed. The method of blending a plurality of pixels on a texture map corresponding to the pixels constituting a polygon, thereby finding texture data to be pasted on to the pixels constituting the polygon, includes the steps of: determining whether or not there are transparent pixels in said plurality of pixels on the texture map; if there are no transparent pixels, blending said plurality of pixels on the texture map in accordance with the ratio with which a pixel constituting the polygon corresponds therewith; if some of the plurality of pixels on the texture map are transparent pixels, substituting the transparent pixels by other adjacent pixels which are not transparent; and if all of the plurality of pixels on the texture map are transparent pixels, ignoring the plurality of pixels on the texture map.
