1. An image processing method implemented by an image processing apparatus, the method comprising: obtaining, an initial high-resolution image from a low-resolution image through image magnification processing; selecting, a central similar block from the initial high-resolution image, wherein the central similar block is associated with a pixel selected from the low-resolution image; determining a direction of a texture of a neighborhood range of the pixel in the low-resolution image; upon the determination, selecting, a search block from the low-resolution image associated with the pixel based on the determined direction; wherein the central similar block and the search block have a same block size; and determining, by the image processing apparatus, a pixel value of the pixel according to the central similar block and the search block.
