Abstract: Disclosed are embodiments of a graphics scene detection technique that provides an adaptive scale factor dependent on an image quality, such that certain images may be downscaled prior to being displayed to preserve system resources without significantly affecting image quality for a user. The inventors recognized and appreciated that certain images may be presented at a lower resolution to a user without being perceived as lower image quality. Some aspects provide a scene detection module that determines a quality score from a graphic command output for an image. Depending on the quality score, the scene detection module may output a quality-aware scale factor that can be applied to reduce pixel resolution of an image before displaying the image to a user. Resultingly, the computing device may be improved by saving system resources including memory bandwidth, processing power for other apps or instances, without negatively affecting visual perception of the scene.
