Abstract

The embodiment of the invention provides a naked-eye 3D display three-dimensional image coding method and a device. The method comprises the steps that viewpoint filling is performed on each sub-pixelaccording to the distance between the pixel center point of each sub-pixel and the optical axis of a unit cylindrical lens covering the sub-pixel; and correcting the pixel value of each segmented sub-pixel according to the areas of the two segmented regions of the segmented sub-pixel and the pixel values of the adjacent sub-pixels of the segmented sub-pixel. According to the naked-eye 3D displaythree-dimensional image coding method and the device, after viewpoint filling is performed on each sub-pixel, the pixel value of each segmented sub-pixel is corrected according to the area of the twosegmented regions of the segmented sub-pixel and the pixel value of the adjacent sub-pixel of the segmented sub-pixel, so that edge sawteeth in the display effect are reduced, the display effect of the stereoscopic display is improved, and the hardware cost can be greatly saved.

Description

technical field [0001] The present invention relates to the technical field of image coding, in particular to a three-dimensional image coding method and device for naked-eye 3D display. Background technique [0002] The grating display technology in the naked-eye stereoscopic display has also begun to be widely promoted and gradually matured. The LCD naked-eye stereoscopic display is composed of an LCD display panel and a lenticular lens grating. It has the advantages of large size, high brightness, seamless splicing, and large depth of field. The lenticular grating has the function of spatial light splitting. Through the spatial light modulation of the cylindrical convex lens, the light emitted by the pixels arranged in different spatial positions on the focal plane is emitted in the direction of the line connecting the optical centers. figure 1 It is a schematic diagram of the principle of the lenticular grating stereoscopic display in the prior art, such as figure 1 As...
