ABSTRACT:
Methods, circuits, and apparatus for handling gamma-corrected texels stored in a graphics memory. On-the-fly gamma-to-linear and linear-to-gamma conversions are performed such that gamma-corrected texels are provided to circuits that are able to process them, while linear valued texels are supplied where needed. In various embodiments, these conversions are done by lookup tables, software instructions, or dedicated hardware. Gamma-corrected texels may be tracked by a shader program, pipeline states, or driver instructions, and may be identified by header or flag information, or by part of a texture descriptor.
