An image processing apparatus includes a memory storing one or more instructions, and a processor executing the one or more instructions stored in the memory, wherein the processor uses one or more deep neural networks to generate first feature maps from a first image, generate second feature maps for each of subpixels based on the first feature maps and position information of each of the subpixels arranged in a display, and determine result values for each of the subpixels based on the second feature maps.
