Abstract: The present application discloses method for generating a panorama image based on a rendering engine associated with a display apparatus. The method includes determining a display model configured to be a polygon prism for a rendering engine corresponding to a panorama view of a scene. Additionally, the method includes using multiple sampling cameras associated with the rendering engine to capture multiple sample sub-images of the panorama view in respective directions towards multiple sub-planes of the polygon prism. The method further includes attaching the multiple sample sub-images to respective multiple sub-planes to form a constructed display model. Furthermore, the method includes rendering the constructed display model by the rendering engine to reconstruct a panorama image and displaying the panorama image on the display apparatus.

IPC: G09G3/3275
Abstract: A display apparatus includes a data driver and a light valve controller. The data driver is configured to continuously provide K display signals, all of which include a same set of image data, to a display panel. K is an integer greater than or equal to 2. The light valve controller is configured to provide a turn-off signal to a light valve whenever the data driver provides one of first T or odd-numbered display signals in the K display signals, and provide a turn-on signal to the light valve whenever the data driver provides one of last (K−T) or even-numbered display signals in the K display signals. T is an integer greater than 0 and less than K, and (K−T) refers to a difference between K and T.
