Description

A kind of dynamic stereo picture appts

The invention belongs to optics display technique field, relate to a kind of device of energy direct viewing dynamic stereo picture.

Chinese patent CN2054928U and CN2094781U disclose the device of several demonstration dynamic images, can be used for showing dynamic landscape picture, and the dynamic landscape mural painting that occurs on the market is exactly wherein a kind of.This picture is made up of picture and the innervation displaying lamp box of being close to thereafter, and along with innervation is showed moving of lamp box window Moire fringe, still frame demonstrates dynamic effect true to nature.Dynamically the picture of landscape painting mostly is the strong scenes of sense of movement such as waterfall, fountain, wave, coloured flag.

A pair of stereo image from the one section short-range observation point picked-up of being separated by, by proper arrangement, each image is only seen by spectators' eyes, then can produce the three-dimensional illusion with depth perception, most three-dimensional films, stereotelevision, stereotome all utilize this principle to make.Watch this class stereo image that two kinds of approach are arranged: a kind of need are worn the branch optical glasses, as polaroid filter, color optical filtering, liquid crystal shutter glasses, deviation prism; The another kind of beam splitter that relies on is sent into left and right sides eyes to stereo image respectively, by the bore hole Direct observation, beam splitter has column mirror grating plate, fly lens plate, slit baffle plate, large-scale curved reflective mirror etc., utilize beam splitter can not only watch stereo image, can also watch from the panoramic image of a plurality of observation point picked-ups.

Chinese patent CN87106723 provides a kind of display means for stereoscopic images, and this device adjusts element by a plurality of light sources discrete and that can independently control and one or more light and control circuit forms according to fixing relation configuration, but the show events stereoscopic image.This device is actually a kind of three-dimensional display, and complexity is very high.

The present invention fully utilizes dynamic display technology and stereo display technique, and purpose provides a kind of easy making, strong sense of reality, and the dynamic stereo picture appts of energy direct viewing.

Dynamic stereo picture appts is by forming with the lower part: beam splitter (1) and transmission-type sampling picture (2) are matched to stereoscopic image, be fixed on the impression window (21) of dynamic displaying lamp box (3), the variation of impression window (21) shadow makes stereoscopic image have dynamic sense.

Beam splitter (1) can be column mirror grating plate, slit baffle plate and other folk prescription of making easily to selecting element, also can select integral photographic elements such as fly lens plate for use.For simplicity, only narrate to the selection element below with folk prescription.

Transmission-type sampling picture (2) is called for short " sampling picture ", be to reconfigure the new image that forms after taking a sample by batten by stereo image or panoramic image, folk prescription is resembled by many faciola shapes to the sampling picture to be formed, new image comprises dynamic scenic spot and static scenic spot, also can all be formed by dynamic scenic spot.The sampling picture can take following several method to make: emulsion directly is coated in the beam splitter back side, and stereo image or panoramic image are exposed to beam splitter by projector, makes developing fixing then and handles; Sensitized paper is close to the beam splitter back side, and stereo image or panoramic image are exposed to beam splitter by projector, takes off sensitized paper then and does the developing fixing processing; Obtain stereo image or panoramic image from scanner, video camera and some video source, by the synthetic sampling of computing machine picture.In back two kinds of methods, beam splitter (1) has certain difficulty with the coupling of sampling picture (2).

The dynamic lamp box (3) of showing utilizes the motion of Moire fringe to make picture produce continuously dynamically sense.The transparent grating band of motion is installed in the lamp box, daylight lamp or other light source are housed in the grating band, the grating band can be done circlewise or drum, is driven by main drive shaft by slowspeed machine, the dynamic scenic spot simulation of sampling picture is flowed, multiple dynamic effects such as rotation, transmission, injection.Dynamic displaying lamp box has three kinds of composing methods: first kind, quiet grating, moving grating, drive unit, light source form by the front and back arranged in order; Second kind, arranged in order forms before and after moving grating, drive unit, the light source; The third is made up of light source and control circuit, and under drives, the brightness of lamp box window selection area changes by certain rule.In the second approach, do not use quiet grating, the dynamic scenic spot of sampling picture must attach the grid line structure when making.

Make dynamic stereo picture appts, at first relate to the design of stereoscopic picture plane, picture can adopt lucid and lively, the dynamic strong scene of color, as waterfall, brook flowing water, ripple, the automobile that goes at express speed etc.Secondly, stereoscopic picture plane is made transmission-type, picture produces flickering during beholder's head move left and right, this is very disadvantageous, can place the position of out of focus a little to post mirror front surface when making the sampling picture with the cylindrieal lens plate exposure, when making the sampling picture with other method, can not keep tangible blank batten between the sampling batten, scintillation can be suppressed preferably; The 3rd, do not overlap fully by dynamic scenic spot stereoscopic or the sampling picture that panoramic image is formed, certain transverse parallaxes dislocation is arranged, the different depth of field, corresponding to different transversion malposition amounts, when designing quiet grating or making dynamic scenic spot grid line structure, must allow the brightness of respectively organizing dynamic scenic spot image corresponding point change synchronously, by this requirement, the grid line of optical grating construction horizontal structure preferably on quiet grating or the picture, simultaneously, because also there is the vertical gate line structure in sampling picture itself, the angle of moving grating grid line and horizontal direction can not be excessive, the sampling picture, quiet grating, moving grating planar requires parallel and close, when the depth of field at the dynamic scenic spot of sampling picture was in the particular design position, the grid line of quiet grating no longer required in the horizontal direction; At last, beam splitter, sampling picture, dynamic displaying lamp box firmly fit together by relation shown in Figure 1, form dynamic stereo picture.

The display means for stereoscopic images that patent CN87106723 provides is to form picture with the controllable light source that drives as pixel, and movable stereoscopic picture plane can be provided, but is difficult for forming true color, high-resolution image, and cost of manufacture and complicacy are all very high.This device has overcome various dynamic menus and has not had the not deficiency of the dynamic sense of tool of stereoscopic sensation, stereogram, the dynamic stereo picture that provides has stereotome and the true lively advantage of dynamic mural painting concurrently, be equipped with the in-site modeling sound that sends by loudspeaker again, build reality environment.The dynamic stereo picture of large format hangs in room, hotel or the exhibition room, but both simulating natural environment has the sensation that increases the space again, and this has realistic meaning for the living environment of improving Modern Family.
