Abstract
A method for generating virtual reality images and used in a light field near-eye display includes steps of: calculating a compensation mask according to a simulated image and superimposing the compensation mask on a target image to generate a superimposed target image, wherein brightness distributions of the simulated image and the compensation mask are opposite to each other; and shifting a display image according to a change vector of a plurality of eye movement parameters, wherein the display image is converted from the superimposed target image. The light field near-eye display is also provided. In this way, the light field near-eye display for generating virtual reality images and the method thereof can achieve the purpose of improving the uniformity of the image and expanding the eye box size.
