Description
The present invention relates to the improvement of a kind of color solid video taking aid and stereoscopic glasses.
The general exploded view (as three-dimensional film etc.) of taking all is that two positions of apery eye take out two different width of cloth videos of both sides respectively, put on special glasses then, make right and left eyes can only see one of them video respectively, reach brain by optic nerve, coincide and just produced stereoscopic sensation together, its shortcoming is to produce out the video that two width of cloth separate, and can only see black and white or monochromatic video.Put down in writing according to China CN86100845A application for a patent for invention prospectus: the double-colored branch of a kind of single-lens monochromatic light roadbed complementary color of Soviet Union Leningrad telecommunications engineering institute design in 1974 resembles the three-dimensional colour television broadcast system, and weak effect is not seen practicality.The color seperation that adopts Moscow State University realizes the scheme of color solid TV, and the huge difficulty or ease of the complicated loaded down with trivial details equipment of its color seperation realize; Nineteen eighty-three, " 10 years from now on televisors " book of Britain issuing was said, not having in 10 years at least from now on can be for practical three-dimensional colour television machine appearance.
CN86100845A application for a patent for invention prospectus has proposed a kind of shooting and display device of stereo colour image, but also has following problems:
1. as shown in Figure 1, two incident light axis directions of this stereoscopic shooting device are parallel, can not change with the adjusting of camera system lens focus, therefore, two optical axis alignments be two points on the scenery of being taken, rather than see thing as people's eyes, the eyeball optical axis direction is arbitrarily adjustable, watch the center attentively and always synchronously aiming at same point on the scenery, that so two light beams of this device for shooting are become in camera system as if dislocation overlaps, do not resemble eyes and overlap well when seeing thing, thereby the influence effect of taking and watching exploded view, when taking nearby scenery, this shortcoming is particularly evident.
2. as shown in Figure 2, in two light paths of this stereoscopic shooting device, the spectral combination of two color filters is segmentation before and after the spectrum, and color filter sees through is λ
0-λ
1Visible light, be bordering on certain coloured light (as blue light), another color filter see through for λ
1-λ
2Visible light, then be another kind of coloured light (as gold-tinted), two-way light beam overlapping imaging on same plane, but because of the shape of two elephants all not identical, two positions that resemble on image plane are also inequality, they can not all overlap, and are example with yellow two color filters of indigo plant therefore, the video that is become behind the light transmission color filter of scenery, intersection a lateral edges do not occur for blue, the opposite side edge then is yellow, thereby makes the exploded view color distortion of taking and watching, and the look limit of similar ghost image occurs.
3. because two imaging light paths of this device for shooting, one is the camera lens of directly injecting camera system, and another is gone into through two secondary reflections are laggard, thereby two light paths have an optical path difference, difference is the distance between back one light path midplane lens and catoptron, i.e. O ' O among Fig. 1 " length.For the same focal length of same camera lens, the object lens of two corresponding light paths should equate that apart from (referring to actual light path) therefore, what camera system was noted simultaneously is not the video of scenery on the same plane on the same imaging surface.Though when taking distant view, difference can be unobvious, (because object lens are apart from the optical path difference much larger than two light paths), but when taking close shot, two videos just have evident difference (significant difference being arranged because the position of two object planes being shot is subjected to the influence of optical path difference), thereby influence into the quality of stereoscopic image.
The objective of the invention is for solving above-mentioned existing problems, carry out new design, a kind of color solid video taking aid and stereoscopic glasses are provided, taking aid is contained in common camera system (as camera, video camera, gamma camera etc.) camera lens front end, just can shoot the potential video of Well-recovered color solid, after showing through common display system (as photo, film, TV etc.), put on special color solid glasses, just can see the color solid video with true shadow thing indifference.
Now the present invention is specified as follows:
(1) structure of color solid video taking aid and principle of work.
1. Fig. 3 is the structural representation of color solid video taking aid.Because common camera system just can be taken the color solid video under this device that adds is assisted, so be called color solid video taking aid (abbreviation taking aid), it mainly is made up of color filter (4) (6), catoptron (2) (3) (7), semi-permeable and semi-reflecting mirror (5), housing (8), Connection Block (9) and catoptron corner governor motion etc., and taking aid links to each other with camera system by Connection Block.
2. Fig. 5 is the taking aid optical schematic diagram.Taking aid has a cover double light path reflection-type BUOY CAMERA SYSTEM, light on the subject A is divided into two bundles, light beam 1 behind color filter (4) and planar lens (5), sees through the camera lens L of camera system through the reflection of catoptron (2) (3) again, resemble flat on imaging A ', light beam 2 is through the reflection of catoptron (7), sees through color filter (6), again through the reflection of semi-permeable and semi-reflecting mirror (5), see through the camera lens L of camera system then, imaging A on image plane ".Because the equal in length of two light paths in the taking aid, thereby can guarantee that two light paths are to the equally clearly imaging of same object plane.
3. the catoptron in the taking aid (2) (7) can rotate around the central shaft of crossing the mirror plane, adjusts the level crossing rotational angle theta
1, θ
2, the intersection point of optical axis of two-beam and the optical axis of object lens L are met at a bit, and thing light enter that the optical axis and the objective lens optical axis of two-beam overlaps behind the object lens, therefore, the central point of two videos overlaps on imaging surface.Link to each other a kind of the be made up of with the lens focus adjusting ring tooth bar, sector gear of level crossing corner governor motion, and (as shown in Figure 4) can make angle θ
1θ
2Adjusting and the adjusting of lens focus carry out synchronously.These characteristics have guaranteed that the video that double light path is taken just overlaps when imaging, the effect when its effect and people's eyes are seen scenery is consistent, thereby has strengthened the stereoscopic sensation of video.
