Method and apparatus for supersampling

A non-transitory computer-readable storage medium storing instructions executable by a processor, to perform:

• generating a current image frame at a first resolution by performing jittered sampling on a first-resolution pixel area of a three-dimensional (3D) scene,
• generating a warped image frame at a second resolution higher than the first resolution, by warping a feedback image frame based on a motion vector corresponding to a difference between the current image frame and a previous image frame,
• obtaining a position-adjusted warped image by adjusting a position of the warped image frame based on a sampling position change corresponding to the jittered sampling, and
• generating a current output image frame by processing the current image frame and the position-adjusted warped image frame through a neural network model.

An electronic device comprising:

• a processor configured to:
• generate a current image frame at a first resolution by performing jittered sampling on a first-resolution pixel area of a three-dimensional (3D) scene based on a first jitter offset,
• generate a warped image frame at a second resolution higher than the first resolution, by warping a feedback image frame based on a motion vector corresponding to a difference between the current image frame and a previous image frame,
• obtain a position-adjusted warped image by adjusting a position of the warped image frame based on a sampling position change corresponding to the jittered sampling, and
• generate an output image frame by processing the jittered sample image frame and the position-adjusted warped image frame through a neural network model;
• and
• a display configured to display the current output image frame.
