Claim 9:
10. A system, comprising:
an image processor configured with instructions in non-transitory memory that when executed cause the image processor to:
determine a motion between a preceding image frame of a sequence of image frames to be rendered and a reference image frame;
rendering a small image for the preceding image frame, the rendered image having a resolution lower than the reference image frame;
upscaling the rendered image to a target resolution of the reference image frame;
detect one or more areas of the rendered image to be blended;
adjusting brightness of the pixels of a motion-compensated stored reference image frame based on a brightness of the pixels of the rendered image; and
generate an output image frame at a target size based on both the rendered image and the motion-compensated stored reference image frame corresponding with a preceding output image frame,
wherein, within the one or more areas of the rendered image to be blended, pixels of the output image frame are the corresponding pixels of the rendered image blended with the corresponding pixels of the motion-compensated stored reference image frame; and
wherein, outside of the one or more areas of the rendered image to be blended, pixels of the output image frame are the corresponding pixels of the rendered image or the reference image frame.
