Neural supersampling method and device

A supersampling method, comprising:

• generating a current rendered image frame by performing jittered sampling on a three-dimensional (3D) scene, based on sub-pixels of low-resolution pixels for the current rendered image frame;
• generating a current warped image frame by warping a previous output image frame, based on a motion vector map corresponding to a difference between the current rendered image frame and a previous rendered image frame;
• generating a current shifted image frame by shifting pixels of the current warped image frame, based on a change in sampling positions based on the jittered sampling;
• and
• generating a current output image frame, based on the current rendered image frame and the current shifted image frame by:
• alternately selecting corresponding sub-pixels of each of the low-resolution pixels for the current rendered image frame, based on a first period;
• and
• alternately sampling sampling points of the 3D scene corresponding to corresponding secondary sub-pixels of each of the selected corresponding sub-pixels, based on a second period.

An electronic device, comprising:

• a memory storing instructions;
• and
• a processor communicatively coupled to the memory, wherein the processor is configured to execute the instructions to:
• generate a current rendered image frame by performing jittered sampling on a three-dimensional (3D) scene, based on sub-pixels of low-resolution pixels for the current rendered image frame;
• generate a current warped image frame by warping a previous output image frame, based on a motion vector map corresponding to a difference between the current rendered image frame and a previous rendered image frame;
• generate a current shifted image frame by shifting pixels of the current warped image frame, based on a change in sampling positions based on the jittered sampling;
• and
• generate a current output image frame, based on the current rendered image frame and the current shifted image frame;
• select target pixels in the current shifted image frame based on the sampling positions of the jittered sampling;
• and
• replace the target pixels with pixels of the current rendered image frame;
• and
• an output device configured to display the previous output image frame and the current output image frame.
