Abstract: The present application discloses method for real-time processing image data based on a rendering engine. The method includes sampling a first set of data in a first pixel arrangement to be displayed as an image in a display screen with pixels in a second pixel arrangement. The method further includes creating a first model mapped with the first set of data to generate a second set of data and a second model mapped with the first set of data to generate a third set of data. Additionally, the method further includes rendering the second set of data using a first shader to output a fourth set of data and rendering the third set of data using a second shader to output a fifth set of data. Furthermore, the method includes superimposing the fourth set of data over the fifth set of data to display a sixth set of data.

Abstract: A method for processing an image in a virtual reality display device comprises determining a gaze area and a non-gaze area in a display area of the virtual reality display device, performing, at a first time instant, a rendering process in the gaze area and the non-gaze area to generate a first image, performing a time warping process on the first image to generate a second image, based on attitude information of the virtual reality display device at a second time instant, and modifying the second image based on the movement information and attribute information of a motion object in the gaze area. The method can avoid problems caused by the time warping process, reduce delays, and avoid smearing or ghosting, and thus obtain a good display effect.
