Abstract: The present disclosure relates to an image rendering method for a computer product coupled to a display apparatus. The image rendering method may include rendering an entire display region of the display apparatus with a first rendering mode to generate a first rendering mode sample image, determining a target region in the entire display region, rendering the target region with a second rendering mode to generate a second rendering mode sample image, and transmitting data of the first rendering mode sample image and the second rendering mode sample image. The second rendering mode comprises at least a value of an image rendering feature that is higher than that of the first rendering mode.

Abstract: A method measuring a distortion parameter of a visual reality device includes: obtaining an anti-distortion grid image according to a first distortion coefficient; obtaining a grid image of the anti-distortion grid image at a preset viewpoint after the anti-distortion grid image passes through a to-be-measured optical component of the visual reality device; determining a distortion type of the grid image after passing through the to-be-measured optical component; adjusting the first distortion coefficient according to the distortion type of the grid image, thereby obtaining an adjusted first distortion coefficient and then reducing distortion of the grid image; repeating the above steps until the distortion of the grid image is less than or equal to a distortion threshold. The adjusted first distortion coefficient when the distortion of the grid image is less than or equal to the distortion threshold, is taken as a distortion coefficient of the to-be-measured optical component.

Abstract: Provided by the present disclosure are a display device and a display method therefor. By detecting the position of a viewer, the display angle of the scene in an image to be displayed is adjusted according to the position of the viewer so as to adapt to the viewing angle of the viewer. Therefore, the image viewed by the viewer can better conform to the real objective scene, and when the viewing angle changes, different angle pictures of an object can be viewed, thereby improving the display effect.

Abstract: A method of dynamically displaying a three-dimensional image object in a volumetric display apparatus is provided. The method includes rotating a display plate about an axis to display a volumetric three-dimensional image; displaying a first three-dimensional image of a first three-dimensional image object according to first coordinates in a first image coordinate system in the volumetric display region; sensing a position or a movement of an external real-world object within a sensing zone; and displaying a second three-dimensional image of a second three-dimensional image object according to second coordinates in a second image coordinate system in the volumetric display region. The second three-dimensional image object is obtained by reorienting the first three-dimensional image object from an initial orientation to a target orientation; and the reorientation is correlated with a position or the movement of the external real-world object.

Abstract: A control method for a head-mounted visual apparatus, a corresponding computing apparatus, a head-mounted visual apparatus and a computer-readable storage medium. The head-mounted visual apparatus has an infrared transceiver including an infrared light source array and an infrared detector. The control method comprises the steps of: driving each sub-light source to emit coherent infrared light to form an interference enhanced scanning light spot on a face of a user who wears the head-mounted visual apparatus; controlling each phase of the coherent infrared light emitted by each sub-light source respectively to make the scanning light spot move in the local area, including eyes, of the face of the user, to realize a scanning of the local area; and using the infrared detector to receive the infrared light reflected from the local area to generate scanning data.
