Abstract
The invention relates to a method for avoiding blind zones in an optical grating three-dimensional display screen, which uses a sensor to identity the positions of human eyes, adjusting the relative position of an optical grating and an image when the human eyes are in a blind zone to actively avoid the lateral inversion of parallax images and solve the blind zone problem, thereby reducing increased multi-parallax images resulted form taking account of blind zones, making the display screen with limited pixels display images more finely, and preventing the blind zones from influencing the market acceptance of optical grating three-dimensional display products due to blind zones.
Description
Technical field
The present invention relates to a kind of grating stereo display, especially a kind of method of avoiding blind zones in optical grating three-dimensional display screen.
Background technology
Raster stereoscopic picture can realize that three-dimensional bore hole watches, and is a kind of mode of well watching of stereo-picture, and people are applied in it on the display screen again in recent years, make it obtain better development.But raster image has the blind area, and the image horizontal parallax of seeing in the blind area is put upside down, and seems very uncomfortable (referring to accompanying drawing).In order to enlarge the visual angle, reduce the blind area, raster image often needs several anaglyph sequences, widens effective vision area with this.But the parallax sequence image that contains on the display screen is many more, and image is just thick more, realizes that video image is also difficult more.See that stereopsis only needs two width of cloth parallax images, other parallax image information is all prepared for other angle, increase the parallax image for increasing the visual angle, this can make image more more coarse concerning the limited display screen of pixel, makes the practical value that realizes stereo display be subjected to very big influence.
Summary of the invention
For optical grating three-dimensional display screen is carried out, allow optical grating three-dimensional display screen be accepted by market, the present invention adopts transducer to discern position of human eye, when human eye is in the position, blind area, display is adjusted grating and image relative position, initiatively avoid anaglyph situation reversed left to right with such method, solve blind zone problem.
Technical scheme of the present invention is: on display screen, adorns a transducer, detects the human eye viewing location, and when detecting human eye and be in the position, blind area, the display unit movable image, perhaps mobile grating, the stereopsis of seeing that horizontal parallax is put upside down is avoided in the blind area of staggering.
The invention has the beneficial effects as follows, by the method for this avoiding blind zones in optical grating three-dimensional display screen, removed the worry of blind area, thereby can reduce the image pixel that loses because enlarge the visual angle as far as possible, it is meticulous again not because of there being the blind area to influence the acceptance in market making image.
Description of drawings
Fig. 1 is a schematic diagram of raster image blind area, on the position, blind area, what left eye was seen is right image, what right eye was seen is left image, the horizontal parallax image that right and left eyes is seen is just put upside down, if at this time mobile half-space grating or mobile row (pixel) image, situation about putting upside down just can obtain correcting.
Embodiment
1. adorn a transducer in the middle of the frame above or below display screen, detect the human eye viewing location, the camera lens of transducer can be concave-sphere, post mirror or pin hole, slit, and the camera lens back is the quick or light-sensitive element of a heat extraction, the heat of temperature-sensitive something or somebody to fall back on; Photosensitive is at the other infrared light that sends of camera lens, face or eye reflections by the people, received by transducer, transducer electrical signal intensity quick to a heat extraction or light-sensitive element compares, if the electrical signal intensity of aiming at the senser of position, blind area exceeds the light-sensitive element of other position, then transducer sends signal, and the notice display unit is done respective handling.
2. working as transducer has signal to send, and then software for display utilizes DIRECTX technology or OPENGL technology, the control video card, cast out the 1st columns certificate on the video memory, promptly cast out the 1st row pixel of image, just image can be moved to the left a pixel, as long as move some images, the blind area is just not blind.
3. there is signal to send when transducer, if not mobile image, also can mobile grating, mobile grating can draw lenticular lenses the right and left with electromagnet, makes lenticular lenses do small physical location and moves, and it is just passable to move half grating space.If show grating by liquid crystal board, then on liquid crystal board, be covered with grating fringe, realize the change in grating slit with display packing.
Claims (4)
1. the method for an avoiding blind zones in optical grating three-dimensional display screen, on display screen, adorn a transducer, follow the human eye viewing location and regulate stop position, it is characterized in that: transducer only detects the position, blind area, when human eye was in the position, blind area, then display unit moved the image of demonstration, perhaps mobile half-space grating, the stereopsis of seeing that horizontal parallax is put upside down is avoided in the blind area of staggering.
2. according to the method for the described avoiding blind zones in optical grating three-dimensional display screen of claim 1, it is characterized in that described transducer is photosensitive or heat-sensitive sensor, the camera lens of transducer can be concave-sphere, post mirror or pin hole, slit, the camera lens back is the quick or light-sensitive element of a heat extraction, the heat of temperature-sensitive something or somebody to fall back on, photosensitive is to send infrared light on the camera lens side, by people's face or eye reflections; Transducer is measured the element that this heat extraction is quick or the light-sensitive element induction is the strongest, if the element signal of aligning position, blind area is the strongest, then this transducer sends signal, makes display unit do respective handling.
3. according to the method for the described avoiding blind zones in optical grating three-dimensional display screen of claim 1, it is characterized in that described when detecting human eye and be in the position, blind area, display unit movable image then; During software for display detects that transducer sends blind area signal, the software control video card shows the position that moves right to the left or to the right by image, staggers with this and watches the blind area.
4. according to the method for the described avoiding blind zones in optical grating three-dimensional display screen of claim 1, it is characterized in that described when detecting human eye and be in the position, blind area, then mobile grating, mobile grating can be with two electromagnet pulling lenticular lenses the right and lefts, make lenticular lenses move the half-space position; If show grating by liquid crystal board, also can on liquid crystal board, be covered with the demonstration striped, realize the change of grating gap position with display packing.
