Abstract

A logical framebuffer may identify pixels areas or blocks of an image that have changed between successive frames. The pixel values of these identified areas may be copied and/or scaled from more recent frames and merged into older frames stored in scanout buffers of an image display system to update older buffers. The logical framebuffer may compare image data at a resolution that is greater than or equal to the resolution of the scanout buffers. Scaling may be used to downscale changed pixel areas frames stored at the higher resolution of logical framebuffer that are to be copied into older frames at the lower resolution of the scanout buffers to update the older frames. Changed pixel areas may also be copied from a newer frame buffered at the lower resolution after the older frame. Latency may be reduced. Image processors, display systems, and methods are provided.
