    Abstract: An image processing method is applied to an image display device, the image display device includes a lens having distortion coefficients and a display screen. The image processing method includes: dividing a display region of the display screen into image regions according to the distortion coefficients of the lens, an outer boundary line of each image region enclosing a polygon, a geometric center of the polygon enclosed by the outer boundary line of the image region coinciding with a geometric center of the lens, and distortion coefficients of positions of the lens on which vertexes of the polygon enclosed by the outer boundary line of the image region are mapped being the same; and performing anti-distortion processing on coordinates of vertexes of the image region according to a distortion coefficient corresponding to the vertexes of the image region to obtain texture coordinates of the vertexes of the image region.

    Abstract: Embodiments of the present disclosure provide a method for driving a display device to display an image sequence and a display device therefor. The display device includes a backlight module having a plurality of backlight partitions. The image sequence includes at least a first frame image and a second frame image. The method includes determining a first region in the first frame image and a second region in the second frame image that correspond to an overlapping portion of the first frame image and second frame image as overlapping regions; obtaining, based at least partially on a first backlight value of a first backlight partition(s) corresponding to the first region, a second backlight value of a second backlight partition corresponding to the second region; and controlling a backlight brightness of the second backlight partition based on the second backlight value when the display device displays the second frame image.
