Embodiment Construction

[0026] A resolution-adjustable sub-pixel arrangement algorithm suitable for lenticular stereoscopic display, wherein the lenticular stereoscopic display is a stereoscopic display with 8 viewpoints whose grating tilt angle is θ, comprising the following steps:

[0027] (1) Convert the stereoscopic image with adjustable resolution: For the case where the original stereoscopic image is converted from a stereoscopic image of 8 viewpoints to a stereoscopic image of k viewpoints, where k is a natural number less than 8, first decompose the original stereoscopic image, and then extract 8 disparity maps, select k disparity images among them and expand the selected k disparity images into 8 new disparity maps, and finally synthesize the new 8 disparity maps into a stereoscopic image;

[0028] For the situation that the original stereoscopic image is a k-viewpoint stereoscopic image to be displayed on an 8-viewpoint stereoscopic display, the original image is decomposed first, then k dis...

Abstract

The invention discloses a resolution-tunable pixel arrangement algorithm suitable for cylindrical mirror type stereoscopic display, which comprises the following steps: firstly converting stereoscopic images with tunable resolution and then carrying out non-integer error pixel compensation on the converted stereoscopic images. The resolution-tunable pixel arrangement algorithm has the advantages that the display of the same stereoscopic image with different resolutions on the same cylindrical mirror type stereoscopic display can be realized, and further, the proposes of combining the display resolution and displaying the stereoscopic images with 8, 4 and 2 viewpoints in a combined manner are achieved.

Description

technical field [0001] The invention relates to the field of sub-pixel arrangement algorithms for stereoscopic display images, in particular to a resolution-adjustable sub-pixel arrangement algorithm suitable for lenticular stereoscopic display. Background technique [0002] At present, the mainstream representative of forming a stereoscopic image by using the parallax method is cylindrical lens grating imaging, which is relatively simple and widely used. The lenticular three-dimensional display technology was first proposed by Sanyo, and later Philips put a lot of effort into research. This technology is to add a lenticular lens grating plate on the LCD screen. The lenticular lens is precisely aligned with the pixels of the LCD screen. The pixel plane is located on the focal plane of the lenticular lens, so that different pixels covered by the lenticular lens are projected in different directions. By controlling the display of the pixels of the LCD screen, the visual image...
