Abstract
An apparatus and method for scaling the power consumption of a video processor is provided. The apparatus includes a video processor having a plurality of video-processing modules for receiving a stream of image signals at an input and producing a processed image stream at an output, wherein the video processor is initially set to process each received pixel of the image stream according to a preset power-consumption level; an evaluator, coupled to the video processor, for determining an objective-quality metric of the pixel characteristics that are indicative of video quality in the image stream; and, a power-management module, coupled to the evaluator, for obtaining a new power-consumption level for the video processor from a predetermined table according to the objective-quality metric determined by the evaluator, wherein the predetermined table contains a number of different arrangements of the video-processing modules to generate a plurality of power-consumption level. Alternatively, the user may also set the new power-consumption level manually.
