Abstract

The invention provides a three-dimensional film shooting device, which simulates an actual situation of a scene seen by two eyes of a person, and adds shooting lenses on common film shooting equipment and television shooting equipment so as to record image information of field scene. As positions of two shooting lenses are different, and are not on the same point, after the field scene is shot, the results of images are not same, and have differences. The two lenses are controlled by an electronic shutter during shooting, so that the two lenses alternately work in vision retentivity characteristic time of eyes, and images of film and television with differences are alternately recorded in storage equipment (film, hard-disk and the like) of the three-dimensional film shooting device. During broadcasting, the images of film and television with differences recorded in the storage equipment of the three-dimensional film shooting device are synchronized with the shooting time to be alternately shown on screens of film and television. Because of the characteristics of vision retentivity of eyes, information of the previous image does not disappear from visual cortex of a brain, and information of the next image comes, so that different kinds of information of images are overlapped in the visual cortex of the brain to form three-dimensional vision.

Description

Stereo movie shooting apparatus

The present invention relates to a kind of three-dimensional stereoscopic visual TV, film shooting device, film source that it is taken and existing various film, the hardware compatibility of televising allow existing various film, the device plays of televising go out to have 3-D view TV, the mute of stereoscopic vision.

Film, TV have become indispensable instrument in human lives, amusement, the information propagation at present.Because when film, television image show, can only reflect the wide and high of object in the image, can't see the degree of depth of object.Plane, no level, picture that promptly can only represented object be stiff, lack on-the-spot authenticity, can not form stereoscopic vision.So since film, TV came out, people just constantly make great efforts to explore development can truly show the three-dimensional three-dimensional film of nature, televise device, development can make the beholder obtain film, the television equipment of sense of stereoscopic vision effect.Up to now, many enforcement three-dimensional films, TV scheme are proposed.But these schemes all can not be with existing film, television projection device compatibility.Utilization trouble, the problem that cost is high fail to solve so far.It can be the unsolved so far great difficult problem of the industry with existing film, television equipment compatibility, three-dimensional film, televise device easy to use, with low cost that film source after a kind of take is provided.

The purpose of stereo movie shooting apparatus of the present invention provide a kind of can with existing film, the hardware compatibility of televising, easy to use, make full use of the filming apparatus of existing film, TV tech, facility, demonstration three-dimensional film, television image.

The principle of stereo movie shooting apparatus of the present invention is to be based upon on the basis of human-eye stereoscopic vision and human eye vision persistence characteristic mechanism.Human eye has eye storage characteristic as you know, one side with a fan is drawn bird, another side draws cage, the rotation fan can see that bird is in cage after alternately meeting one's eyes by the two sides of fan, in other words on the fan on picture of bird and the fan picture of cage formed the new picture of a width of cloth because the effect of eye storage characteristic has been merged in human brain by human eye.If it is independently most of identical with two width of cloth, the discrepant picture of part is replaced above-mentioned fan two sides drawn bird and cage, after repeating above-mentioned action rotation fan, at this moment under the effect of human eye vision persistence characteristic, see must be two width of cloth parts discrepant be drawn in the human brain merge after, a width of cloth that forms on fan independently is different from the new picture that original two width of cloth are drawn.If before two width of cloth picture respectively appeared at human eye when fan rotated once is a display cycle.So because in a display cycle, information identical in the picture that two width of cloth are drawn was because of occurring twice, so cause twice of nerve impulse after exciting nerve.Difference image information in two width of cloth images was because only occurred once, and exciting nerve causes that nerve impulse respectively once.The caused nerve impulse of image information that can draw same section on the independent discrepant image of two width of cloth thus is better than the conclusion of the nerve impulse that difference part image information causes on the image.The image that these exist simultaneously in cerebral cortex and have strong, the weak different nerve impulse of distinguishing is not common plane can cause.Behind their fusions through the visual cortex of brain, forming one according to the degree of nerve impulse power is not the vision imaging that the plastic relief sense is arranged on plane.If in like manner allow two discrepant image frames of film, TV replace the discrepant picture in fan two sides, Alternation Display in the time of human eye vision persistence characteristic effect, the discrepant independent film of two width of cloth pictures, the caused nerve impulse of television image are sent to the visual cortex of brain, by too can (same section of picture occurs twice according to above-mentioned reason behind the fusion of cortex, with deep impression, so nerve impulse is strong; The part of difference occurs once in the picture, and impression is flat, so nerve impulse is weak) the strong and weak different nerve impulse of generation in the brain visual cortex simultaneously.Forming one after merging in people's brain visual cortex is not the visual pattern that the plane has the plastic relief sense.The enforcement of stereo movie shooting apparatus of the present invention is to form principle of stereoscopic vision soon after two discrepant image informations successively enter human brain according to above-mentioned people two, merges the result that the back produces by the human brain central nervous system.During enforcement with a plurality of taking lenss by they in the human eye vision persistence characteristic time alternation therefore because a plurality of taking lenss will not obtain several variant, incomplete same two dimensional surface pictures on the same point when taking same scenery.Allow these variant incomplete same two dimensional surface image informations utilize film, TV screen in the human eye vision persistence characteristic time, successively to enter human brain then, be sent to the visual cortex of brain by eyes.Reason owing to the human eye vision persistence characteristic, the information of last width of cloth picture does not also disappear in the visual cortex of brain, the information of back one width of cloth picture has arrived, variant so incomplete same image frame information is overlapping in the visual cortex of people's brain, just produced when watching a width of cloth plane picture strong, the weak different nerve impulse effect that can not cause.These strong, weak different nerve impulses are by the visual cortex fusion generation stereoscopic vision of brain.

Stereo movie shooting apparatus of the present invention has solved three-dimensional film, TV and existing film, the hardware compatibility of televising, a difficult problem easy to use, with low cost fully.

Stereo movie shooting apparatus of the present invention is to finish by following method: well-known, have only a taking lens in existing film, the TV production equipment, the picture of on-the-spot scenery records in the image information storage facilities (film, hard disk ...) of film, TV by this taking lens.Stereo movie shooting apparatus anthropomorphic dummy two of the present invention is the actual conditions of scenery soon, increase a production camera lens on common film, TV production equipment, write down on-the-spot scenery image information.Because the position difference of these two production camera lenses is not on same point, therefore also different, variant to the picture result after the on-the-spot scene shot.With two camera lenses of electronic shutter control, make their alternations in the human eye vision persistence characteristic time during shooting, so being recorded in the stereo movie shooting apparatus storage facilities (film, hard disk ...) of being replaced of discrepant film, television image.When broadcasting, discrepant film, the television image that is write down by the stereo movie shooting apparatus storage facilities is synchronized with appearing on film, the TV screen that shooting time replaces.Because human eye vision persistence characteristic, the information of last width of cloth picture also do not disappear in the visual cortex of brain, the information of a back width of cloth picture has arrived, and variant so incomplete same image frame information is overlapping in the visual cortex of people's brain.In the time of human eye vision persistence characteristic effect, in institute's movie, the telefilm, same section information can occur twice in two adjacent width of cloth films, the television image, therefore causes that nerve impulse is stronger; The partial information of difference only occurs once in the picture, therefore a little less than the nerve impulse that causes.These strong, weak different optic nerves impulsions, the visual cortex of brain produced when watching the plane picture strong, the weak different nerve impulse effect that can not cause.Visual cortex by brain merges generation stereoscopic vision.

When stereo movie shooting apparatus of the present invention is worked, two production camera lens alternations continuously always, because their parameter, position are different, the tv screen after the shooting is difference just, difference occurs.Synchronous with the process of taking movie and television film when playing movie and television film, the projection equipment that passes through that discrepant different pictures information record replaces equally broadcasts.People's eyes have eye storage characteristic, and human is observed when seeing an object, if this object suddenly disappears, the information that this object stays in human eye will could disappear every a period of time.In the time of human eye vision persistence characteristic effect, discrepant two width of cloth independence video images show that successively human brain continued to receive second width of cloth image frame information before last width of cloth image frame information disappears.The independently variant video image picture of two width of cloth inequality is overlapping in human brain, produces the three-dimensional on-the-spot outdoor scene visual impression that the degree of depth is arranged through in the human brain nervous centralis and back.Because the tv screen information of stereo movie shooting apparatus record does not have other specific (special) requirements and common kinematograph, television camera just the same when playing, therefore can make full use of existing various film, the equipment of televising.Compatible fully with existing film, television equipment.
