Methods and systems for accelerated image rendering with motion compensation

A method, comprising:

• determining motion between a preceding image frame and a target image frame;
• responsive to the determined motion indicating a scene change or complex motion, rendering the target image frame at a target resolution;
• and
• otherwise rendering a small image based on the determined motion, the small image having a lower resolution than the target resolution, and generating the target image frame based on the small image and a motion-compensated reference image frame of the target resolution.

A system, comprising:

• an image processor configured with instructions in non-transitory memory that when executed cause the image processor to:
• calculate motion between a preceding image frame of a sequence of image frames and a target image frame to be rendered;
• render a small image with a size smaller than a target size of the target image frame based on the calculated motion;
• and
• generate the target image frame at the target size based on the small image, the calculated motion, and a stored preceding reference image frame of the sequence of image frames, the stored preceding reference image frame being of the target size.
