Abstract

The 3D image display method for 2D image frames is a new image display method. The method processes one frame of 2D image frame into multiple image frames with differences. Using synthetical function of central nervous system of human brain, and eye storage characteristic of human eyes, the method forms 3D image capable of reflecting site scene with deepness from 2D image frames. Thus, the method can simulate ordinary 2D image frames obtained by using producing, playing and receiving devices into 3D image display with deepness.

Description

Simulated three-dimensional image display method with two-dimensional frames

The present invention relates to a kind of display packing that the common plane image simulation can be become have degree of depth three-dimensional picture.

Along with the progress of society, image propagates is accepted knowledge to become the mankind, information, the indispensable means of amusement.But existing various image propagates production method of reseptance and instrument such as film, TV, computer ... all can only show the plane of the subject image of producing, i.e. the height and width of the object of producing be can't see the degree of depth of object.These two-dimensional pictures that lack the degree of depth are stiff, not lively, can't form the distinctive on-the-spot sense of reality of stereoscopic vision.In order to address this problem, people have taked the whole bag of tricks, but produce little effect.Can find out that a kind of can to utilize existing production, broadcast, receiving equipment to carry out the demonstration that two-dimensional image has the degree of depth be world today's culture and media industry urgent problem.

The purpose of two-dimensional picture three-dimensional image display method of the present invention provides a kind of new method for displaying image, can utilize existing production, broadcast, receiving equipment that the stereo-picture that common two-dimensional picture stimulated one-tenth has the degree of depth is shown.

The main cause that well-known stereoscopic vision forms is the relation of binocular parallax.The picture that just same object forms on two eyes retinas is inequality.Right eye sees that toward right-hand the right flank of object is more, and left eye sees that toward left the left surface of object is more, and the different information of two width of cloth pictures enter in the human brain simultaneously by optic nerve, and are comprehensive through the mesencephalic centre nervous system, form lively three-dimensional on-the-spot outdoor scene vision.In other words the on-the-spot outdoor scene visual impression of stereoscopic picture plane is to produce through central nervous system is comprehensive after two discrepant image informations enter human brain.Around this principle people have invented two and have had on three-dimensional film, the TV that left and right different polarization light microscopic sheet is watched respectively.When this three-dimensional film, television projection, need two projectors to work simultaneously, different polarised light eyeglasses makes two can only see wherein mute information that film, television projector are play separately respectively.Such two what see separately is two different films, and television projector is play discrepant movie or television picture.After these discrepant films, television image information enter human brain by optic nerve, comprehensive through the maincenter cerebral nervous system, form on-site tridimensional outdoor scene visual impression.But wear the three-dimensional film TV that left and right different polarization light microscopic sheet watches with eyes and implement very trouble, inconvenience can't be popularized.Simulated three-dimensional image display method with two-dimensional frames of the present invention is after two discrepant image informations enter human brain simultaneously according to three-dimensional outdoor scene vision exactly, principle by the comprehensive back generation of human brain central nervous system, the eye storage characteristic that utilizes human eye to have, same width of cloth two-dimensional picture is processed into several are variant, incomplete same two-dimensional picture allows these variant incomplete same two-dimensional picture information successively enter human brain by eyes then.Reason owing to the human eye vision persistence characteristic, the information of last width of cloth picture does not also disappear in human brain, the information of back one width of cloth picture has arrived, variant so incomplete same image frame information is overlapping in human brain, by be formed with behind central nervous system comprehensive the degree of depth can the on-the-spot outdoor scene of real embodiment 3-D view.

Simulated three-dimensional image display method with two-dimensional frames of the present invention has solved the requirement of common plane image stereo display fully.Can be used on existing various image propagates, production, the receiving tool, as film, TV, computer ... simple and convenient.

Simulated three-dimensional image display method with two-dimensional frames of the present invention is to implement to finish by following way: we know existing various image propagates, production, receiving tool such as film, in the picture of the consecutive image that TV is shown, difference between adjacent two width of cloth pictures is very little, carefully just can't not differentiate, visually can regard the same painting face as fully.When various image propagates, production, receiving tool such as film, when the picture of adjacent two width of cloth images has had the variation at brightness, colourity, contrast, picture center in their shown continuous pictures of TV, just produced the effect that same width of cloth two-dimensional picture is processed into two variant incomplete same two-dimensional pictures.On existing various image propagates, production, receiving tool, load onto electronic switch like this, allow the switch operating rate of this electronic switch simultaneously less than time of human eye vision persistence characteristic.The variation at the brightness of display frame, colourity, contrast, picture center on electronic switch control image propagates, production, the receiving tool.Electronic switch is constantly closed, open-minded in less than the time of human eye vision persistence characteristic during work.Brightness on the picture of image production that electronic switch controls, propagation, receiving tool, colourity, contrast, picture center are changed.The image production, the variation at brightness on the picture of propagation receiving tool, colourity, contrast, picture center causes the difference on their shown image frame information.Because the time of electronic switch closes is less than the time of human eye vision persistence characteristic.In the shown consecutive image of this sampled images production, propagation, receiving tool, adjacent two variant incomplete same image informations constantly successively enter human brain by optic nerve, last width of cloth impression does not also disappear, back one width of cloth has come again, overlapping image information is comprehensive through the human brain central nervous system, is modeled to the outdoor scene three-dimensional picture that truly has on-the-spot sensation.Forming three-dimensional outdoor scene vision is after two discrepant image informations enter human brain simultaneously, by the effect same that the refreshing system synthesis of people's mesencephalic centre produces, has reached the purpose that two-dimensional picture stimulated three-dimensional image shows.

Embodiment: stereo-vision television machine.The television set industry has been a very maturation now, the disclosed industry of technology.Technical staff in field of television work knows that television set is mainly by tuner (tuner), intermediate-frequency channel (video detection, sound demodulation circuit), audio signal processing circuit, video processing circuit (brightness, chrominance circuit), the partly composition such as field deflection circuit, horizontal equilibrium flyback transformer, system, control circuit and switching circuit of going.Wherein the function of video processing circuit is that composite video signal with 0～6M is separated into luminance signal, carrier chrominance signal, row field sync signal and is sent to interlock circuit respectively, brightness, colourity, the center of the display frame of control TV.So make TV picture displayed generation brightness, colourity, center change the parameter that only needs to change components and parts in the video processing circuit, isolated luminance signal, carrier chrominance signal, row field sync signal data variation are got final product, because after the luminance signal of data variation, carrier chrominance signal, row field sync signal were sent to interlock circuit, corresponding variation also can take place in the brightness of TV display frame, colourity, center simultaneously.Allow it work in the time less than the human eye vision persistence characteristic with electronic switch (common sequential oscillating circuit), the component parameter of control of video signal processing circuit changes, and its isolated brightness, colourity, row field sync signal are changed simultaneously.These brightness that change, colourity, row field signal impel the brightness of television set picture displayed, colourity, center corresponding the variation to occur.Because the operating frequency of electronic switch (common sequential oscillating circuit) is less than the time of human eye vision persistence characteristic.The variation of television set display frame is also less than time of human eye vision persistence characteristic, last width of cloth image information does not also disappear from human brain when showing like this, second width of cloth has just come, and multi-picture information overlaps in human brain, the 3-D effect of the on-the-spot outdoor scene that the generation human eye is seen.Specific practice is to increase a video processing circuit in TV set circuit, the component parameter of two video processing circuits is different in the television set, because the component parameter of two video processing circuits is different, composite video signal is different fully by the data that two different video processing circuits separate back brightness, colourity, row field sync signal.After different brightness, colourity, row field sync signal data alternately were sent to interlock circuit, television set showed that brightness, colourity, the center of television image is different, occurs changing.Power connection, disconnection with two video processing circuits of electronic switch (common sequential oscillating circuit) control, allow their alternate turns work in less than the time of human eye vision persistence characteristic, the television image of demonstration was changed in the time of human eye vision persistence characteristic.
