1. An image processing apparatus for generating a high-resolution moving image, the image processing apparatus comprising:
a memory storing one or more instructions; and
a processor configured to execute the one or more instructions stored in the memory,
wherein the processor is configured to:
extract feature information regarding a low-resolution image of a current frame by using a first convolutional neural network (CNN),
generate, based on the feature information, a first high-resolution image of the current frame,
remove flickering of the first high-resolution image to generate a second high-resolution image of the current frame, by using a flickering-removed high-resolution image of a previous frame, whereby the second high-resolution image is a flickering-removed high-resolution image of the current frame, and
remove flickering of a high-resolution image of a next frame generated from a low-resolution image of the next frame, by using the second high-resolution image of the current frame.
