Abstract
The present invention relates to a polarized light parallax type stereo display. The present invention is suitable for a manufacturing method of realizing stereo display by a plane display screen and is particularly applied to a television display system. The present invention is characterized in that left image signals and right image signals are alternatively crossed together to form a path of video signals; simultaneously, orthogonal polarizing filters of polarized light are correspondingly connected to the surface of a screen; corresponding polarized light eyeglasses are worn to separate left image pictures and right image pictures, and parallax type stereo display is completed. The present invention has the advantages of low cost, favorable stereo display effect and easy realization. The present invention can be completely compatible with the existing two-dimensional television system.
Description
A kind of polarized-light parallactic formula stereo display method is about on plane picture, finishes the manufacture method of stereo-picture display effect, especially is applied in television display system.
As far back as the fifties, a kind of aperture plate parallax-barrier formula stereo display method has just appearred in the U.S., and it is that the people is on certain viewing location, by slit light barrier fixing before the screen, finish images of left and right eyes and watch different image scene, the fusion of process human brain obtains stereoscopic visual effect.This method is simple, need not wear glasses, but the image information loss amount is bigger.Meanwhile, multiple 3 D image display method occurred, and had relative merits separately, wherein, main is the compatibility of failing to resolve stereo image display system and plane image display system, makes the application of stereo display technique be very restricted.
Fundamental purpose of the present invention realizes that exactly stereo image display system and plane picture display system are compatible fully.
In order to obtain all images information of true scenery, with two video cameras, the left eye and the right eye that are equivalent to the people, absorb a scene simultaneously, obtain a pair of left and right vision signal,, take different left and right image-based chrominance signals respectively through after the synchronous processing, coding is synthetic, obtains containing the composite video signal of left and right image information.Corresponding, as to form by left and right image pixel display frame, on image pixel, bonding one deck polaroid, from left and right image pixel, the direction of polarized light difference that obtains by polaroid.Wear corresponding polariscope, make left eye see the image frame of left side video camera, right eye is seen the image frame of the right video camera, utilizes the not high characteristics of resolution of eye, synthesizes the color solid image.
In the reality,, the orthogonal polaroid of polarized light is bonded on the left and right image pixel in order to reach the best spectrophotometric result of polarized light.
Obtain fine and smooth stereo-picture picture, screen surface is divided into discrete pixel, on the pixel of left and right image, bonding polaroid obtains by the synthetic polarized light image information of left and right image pixel.
When bonding polaroid, being critical is connected on the image pixel, the polarized light by polaroid on the pixel, the just locational error of no one's eye.Therefore, in kinescope, polaroid is bonded between fluorescent powder and the glass bulb.
The stereoscopic sensation that this stereo-picture shows is strong, contain left and right image information composite video signal can with the television transmission system compatibility, finish the color solid image and show.And, do not influence quality and effect that plane picture shows.
Embodiment:
In left and right image display frame, by odd-numbered line and even number line left and right image information is separated, add the polarized light film that iodine makes with polyvinyl alcohol, separate left and right image polarized light.On display surface, the bonding horizon light polarization film of odd-numbered line, the bonding vertical light polarization of even number line film, alternate combination constitutes a complete image frame in the plane.
Claims (5)
1. a polarized-light parallactic formula stereo display method is formed display frame by left and right image pixel, it is characterized in that on image pixel, and bonding one deck polaroid, from left and right image pixel, the direction of polarized light difference that obtains by polaroid.
2. according to the stereo display method of claim 1, it is characterized in that the orthogonal polaroid of polarized light is bonded on the left and right image pixel.
3. according to the stereo display method of claim 1 or 2, it is characterized in that on the pixel of left and right image bonding polaroid.
4. according to the stereo display method of claim 1 or 2, it is characterized in that in kinescope, polaroid is bonded between fluorescent powder and the glass bulb.
5. according to the stereo display method of claim 1, it is characterized in that on display surface the bonding horizon light polarization film of odd-numbered line, the bonding vertical light polarization of even number line film.
