1. An image processing apparatus comprising:
a first image processor configured to up-sample an original low-resolution image on the basis of deep learning-based learning data to generate a first high-resolution image;
a second image processor configured to interpolate the original low-resolution image to generate a second high-resolution image;
a third image processor configured to generate a difference image between the first high-resolution image and the second high-resolution image, extract a high frequency component from the difference image, and amplify the extracted high frequency component; and
a fourth image processor configured to add the amplified high frequency component to the first high-resolution image to generate a target high-resolution image.
