APPARATUS AND METHOD FOR NEAR-EYE DISPLAY BASED ON HUMAN VISUAL CHARACTERISTICS

摘要

The present disclosure discloses near-eye display method and apparatus based on human visual characteristics, and the method includes: dividing a near-eye display screen into n display subregions; acquiring critical spatial frequencies corresponding to the n display subregions respectively; creating and rendering corresponding video image data of n layers for the n display subregions from an input video image according to the critical spatial frequencies corresponding to the n display subregions respectively; transmitting the video image data of the n layers to the near-eye display; and finally, performing reconstruction on and stitching the video image data of the n layers to generate an image which accords with a human gaze effect, and displaying the image in the display screen. The control method of the near-eye display according to the present disclosure may greatly decrease an amount of data transmitted from an image generating source to the near-eye display, reduce a transmission bandwidth, support higher display resolution and refresh rate, reduce power consumption, accord with spatial distribution characteristics of human eyes and meanwhile alleviate a dizzy phenomenon.
