Description

A kind of stereoscopic image processing device that is used for the high score three-dimensional display

[technical field]

The utility model belongs to the stereo display technique field, more particularly, relates to the 2D view data is converted to the stereoscopic image processing device of 3D rendering data.

[background technology]

Traditional image is a kind of two-dimensional information carrier, and it can only show the content of scenery and ignore the far and near position even depth information of object, is incomplete therefore.Stereo display technique can reappear the scene of objective world truly, shows depth perception, stereovision and the authenticity of scene, becomes the important directions of current Display Technique development.The stereo display mode of image is generally left and right two Eye imagings of two camera anthropomorphic dummies about image generation end is used, produce a pair of anaglyph signal or directly directly obtain the anaglyph signal with binocular camera, earlier this anaglyph signal is handled afterwards, be encoded into a row the first from left and be listed as right alternate images signal, just stereo-picture is handled, on display screen, alternately show at last, the grating switch control of right and left eyes sight line before being installed at liquid crystal display screen, make two of the people to see the right image that replaces of row the first from left row respectively, thereby obtain third dimension.

In the existing three-dimensional display, the resolution of three-dimensional display is subject to the stereo-picture image source, the physical resolution intrinsic with display, the resolution of the image that it represented has only half of the intrinsic physical resolution of three-dimensional display, can cause very big influence to the stereoeffect of image than low image resolution, development along with video display and technique for taking, the stereo format parallax video source of high definition is more and more, it is also convenient further to obtain, adopt more high-resolution liquid crystal display screen to be applied to three-dimensional display, thereby increase the display resolution of video image, improve the stereoeffect of image, become a kind of trend and common recognition.
