1. An image processing method comprising:
generating a second image by applying noise to a first image, as a first process; and
generating a third image by upsampling the second image through a neural network, as a second process,
wherein the second image is generated by applying noise to the first image expressed in a second bit depth higher than a first bit depth of the first image and then restoring the bit depth to the first bit depth.
