1. A method of operating an image processing apparatus, the method comprising:
generating a first feature map by performing a convolution operation between a first image and a first kernel group;
generating a second feature map by performing a convolution operation between the first image and a second kernel group;
generating a combination map by summing the first feature map and the second feature map;
generating a second image based on the first feature map and the combination map; and
generating a reconstructed image of the first image, based on the second image and the first image, and generating a high-resolution image of the first image by inputting the reconstructed image to an upscaling model,
wherein a size of at least one kernel included in the first kernel group and a size of at least one kernel included in the second kernel group are equal to each other,
wherein a dilation rate of the second kernel group is greater than a dilation rate of the first kernel group, and
wherein a number of kernels included in the first kernel group is equal to a number of kernels included in the second kernel group.
