Abstract

Systems, apparatuses, and methods for performing color channel correlation detection are disclosed. A compression engine performs a color channel transform on an original set of pixel data to generate a channel transformed set of pixel data. An analysis unit determines whether to compress the channel transformed set of pixel data or the original set of pixel data based on performing a comparison of the two sets of pixel data. In one scenario, the channel transformed set of pixel data is generated by calculating the difference between a first pixel component and a second pixel component for each pixel of the set of pixel data. The difference is then compared to the original first pixel component for each pixel. If the difference is less than or equal to the original for a threshold number of pixels, then the analysis unit decides to apply the color channel transform prior to compression.
