Texture filtering method for e.g. graphical card of mobile telephone, involves performing interpolation by utilizing four points belonging to version of texture or eight points belonging to two consecutive versions of texture

摘要

The method involves determining a set of three co-ordinates of each pixel of image to be constructed, where two of the co-ordinates represent a position of the pixel in the image and the other co-ordinate represents a zoom factor. The zoom factor is compared with respect to a predetermined threshold. An interpolation is performed with respect to the comparison by utilizing four points belonging to a version of a texture or eight points belonging to two consecutive versions of the texture. Independent claims are also included for the following: (1) a graphical circuit for filtering texture (2) a mobile telephone comprising a graphical circuit.
