Software-based acceleration color correction filtering system

摘要

A color correction filtering system filters color video data by compensating for non-linearities and color characteristics specific to a color monitor. Color video data is received by the system, for example through a web browser, and in an accelerated manner passed through a pre-calculated gamut-shifting array. The color correction filtering system gamma decompensates incoming color video data referenced to a non-linear color space through use of a linearization filter. The gamut-shifting array may contain pre-calculated compensation values stored in a plurality of look-up tables. A non-linearization filter is applied to the gamut-shifted color video data to produce color video data compensated for non-linearities specific to the color monitor.
