Abstract: The present disclosure is related to an image processing method of virtual reality. The image processing method may include obtaining position information of a gaze point; performing a compression process on an original image to obtain a compressed image based on the position information of the gaze point; performing a compression process on a distorted image of the original image in an lens to obtain a compressed distorted image based on the position information of the gaze point; and performing an anti-distortion process on the compressed image to obtain an anti-distortion image based on a relationship between the compressed image and the compressed distorted image. The position information of the gaze point may be position information of a gaze point of a user's eye on an original image.
