Embodiment Construction

[0026] A typical embodiment of a method for generating a synthetic image for reducing pseudo-stereoscopic images according to the present invention will be described in detail below, so as to further describe the present invention in detail.

[0027] The synthetic graph generation method of the present invention comprises the following steps:

[0028] Step 1: Choose a 46-inch monitor with a horizontal resolution of 1920 and a vertical resolution of 1080, and measure its length and width with a tape measure to 1018.08 mm 、572.67 mm , the calculated subpixel width is 0.17675 mm . Of course, in other embodiments, all expected autostereoscopic displays can be used, not limited to the types listed here, and the resolution can also be selected according to different requirements;

[0029] Step 2: In order to facilitate the understanding of the technical solution of the present invention, assuming the specific design parameters of the grating, the inclination angle is set to be...

Abstract

The invention provides a composite image generating method capable of weakening an auto-stereoscopic display counterfeit stereoscopic image. According to the method, N disparity images are utilized, and the N disparity image is processed to generate a composite image. In the visual area generated through display of the composite image, a correct stereo visual area is as wide as N-2 sub-visual-areas, a two-dimension visual area is as wide as one sub-visual-area, and a counterfeit stereo visual area is as wide as one sub-visual-area. By the adoption of the method, the width of the counterfeit stereo visual area can be reduced, incorrect parallax in the counterfeit stereo visual area can be reduced, so that asthenopia caused during auto-stereoscopic display watching is weakened, and then the comfort level for watching is increased.

Description

technical field [0001] The invention relates to a method for generating a composite image for autostereoscopic display, in particular to a method for generating a composite image for reducing pseudo-stereoscopic images. Background technique [0002] Autostereoscopic displays are composed of 2D display screens and gratings with spectroscopic effects. Viewers can perceive shocking stereoscopic effects without wearing auxiliary equipment. This is the mainstream direction of future TV development. against N viewpoint ( N Generally 4, 5, 8, 9) autostereoscopic displays, due to the characteristics of the grating itself, can produce repeated viewing areas. Each viewport has 1— N The sub-viewports generated by disparity maps are composed of sub-viewports, and most of the adjacent sub-viewports can provide the correct stereoscopic effect. However, the adjacent sub-viewports at the transition position of the two viewports will provide false stereoscopic effects. At this time, the ...
