Graphical texture mapping
By employing an improved anisotropic filtering method in the graphics processing system, combining different numbers of samples at detailed and non-detailed mipmap levels, the texture mapping error problem under oblique viewpoints is solved, image quality is improved and artifacts are reduced.

Abstract
The invention is entitled "Graphics Texture Mapping". When sampling a pair of mipmaps, anisotropic filtering is performed when sampling a texture to provide output sampled texture values used when rendering output in a graphics processing system, more positions 60 along the anisotropic direction 61 are sampled in a more detailed mipmap level 62 compared to a less detailed mipmap level 63.
