Method and apparatus with tile-based image rendering

An electronic apparatus, comprising:

• a control processor;
• and
• a graphics processing unit (GPU) configured to perform image rendering based on control of the control processor,
• wherein the GPU comprises:
• processors configured to execute instructions;
• and
• a memory storing the instructions, wherein execution of the instructions configures the processors to:
• determine first color values of a first portion of pixels, the first portion of pixels being pixels of plural pixels in a tile frame corresponding to a partial region of an input frame, the tile frame including an edge region and a non-edge region, by performing shading on the first portion of pixels;
• and
• determine second color values of second pixels of the non-edge region, the second portion of pixels being pixels of the plural pixels not included in the first portion, by performing neural network-based super-sampling processing on the second portion of pixels;
• and
• a graphics memory configured to store a rendered tile frame comprising the first color values of the first portion of pixels and the second color values of the second portion of pixels,
• wherein the determining of the first color values comprises determining edge color values of pixels in the edge region by performing shading on the pixels in the edge region of the tile frame, and
• wherein the super-sampling processing for determining the second color values is performed without using color values of pixels included in other tile frames located around the tile frame.
