Patent ID: 8212835

Claim:
A system for performing a texture filtering operation, the system comprising: a memory configured to store a MIP map that includes a first image map that is a highest resolution image map within the MIP map; and a shader unit coupled to the memory and configured to: perform a first texture filtering operation using the first image map to compute a first sample value, perform a second texture filtering operation using the first image map to compute a second sample value, wherein the second texture filtering operation magnifies a texel within the first image map to cover multiple pixels and is a different type of texture filtering operation than the first texture filtering operation, determine that a level of detail (LOD) value indicates the first image map is associated with a minified LOD and the first image map is also associated with a magnified LOD, and blend the first sample value and the second sample value to produce a final sample value, wherein a first weight is assigned to the first sample value and a second weight is assigned to the second sample value based on the LOD value.
