  • Publication number: 20210056719
    Abstract: A method for processing an image in a virtual reality display device and a related virtual reality display device are provided. A gaze area and a non-gaze area are determined in a display area of a virtual reality display device. At a first time instant, a rendering process is performed in the gaze area and the non-gaze area to generate a first image. Based on attitude information of the virtual reality display device at a second time instant, a time warping process is performed on the first image to generate a second image. Based on the movement information and attribute information of the motion object in the gaze area, the second image is modified. With the modifying the second image, problems caused by the time warping process can be avoided, delays can be reduce, and smearing or ghosting can be avoided, thus a good display effect can be obtained.
