Abstract
A system and method for adjusting pictures minimizes the impact on graphics processing performance of a discrete processor. A hybrid system configuration includes the discrete processor and an integrated processor, where the discrete processor typically consumes more power and provides greater processing performance compared with the integrated processor. A picture is produced by a video or graphics engine of a discrete processor within a hybrid system. Each picture is then transferred to a back buffer in the host processing memory. The picture is analyzed to produce picture analysis results that are used to generate adjustment settings. The back buffer is swapped to become the front buffer and the adjustment settings are applied to the picture by an integrated processor to display an adjusted picture. The adjustment may be used in conjunction with power saving techniques to maintain the image quality when display backlighting is reduced.
