Abstract
The respective quadrature of film, video recording or the television image that obtains with twin camera (or double TV television camera tube) alternating camera as eyes is done the projection that links up for connecting (film, video recording or TV) image, that alternating image is because of the overlapping generation stereo visual effect of persistance of human vision, when this three-dimensional visual image per second is no less than 16 frames, produce continuous movable image, when the clear condition of looking satisfies, onlooker and obtain clear unique stereo visual effect.In view of the above, new three-dimensional film, three-dimensional video and the design of stereoscopic TV structure have further been provided.
Description
The present invention belongs to the method that physiological optics, radioelectronics are applied to make three-dimensional film, three-dimensional video, stereoscopic TV.
The prior art data is by retrieval: 1, the three-dimensional film of existing band polarised light glasses.Once did the three-dimensional film experiment with left and right sides image frame alternative method in one's early years both at home and abroad.2, United States Patent (USP) 4309074,4399456, PCT patent 8301-719, People's Daily's report day the present invention's on March 12nd, 1985 the stereoscopic TV without glasses.3, do not do all retrievals, other situations are not quite clear.
Purpose of the present invention obtains to have the method for the live image of unique stereo visual effect clearly for providing a kind of: the new method of making three-dimensional film, three-dimensional video, stereoscopic TV.
Three-dimensional film and three-dimensional video:
Two camera lens are just like eyes, (black and white or colour) shooting for consecutive image is that two video cameras hocket, between shooting f(〉=0), each video camera branch is taken the photograph and is obtained blank spaces △+2f, continue the interrupted image of △, taking the photograph film or video recording are correspondingly alternately coupled together by f uniformly-spaced do the projection that links up.Referring to figure (1).
The moment of supposing onlooker's eye nethike embrane video signal that reception is reflected is t, is t from the eye nethike embrane to optic chiasma top video intersection neurotransmission signal time, the persistence of vision time is e(≈ 1/16 second), so, following lasting interval will intermittently be received in video intersection
……
Signal, when △≤e, every frame image continues:
(t+d, t+ △+d+e) the first frame image duration
(t+d+ △+f, t+d+2 △+e+f) the second frame image duration
……
Therefore, when △≤e, onlooker's video intersection will intermittently alternately obtain the signal from two (camera lens) eye, and at this moment, f-e is exactly the video blanking time of onlooker's video intersection, thereby, if f=e is nonseptate between the then adjacent two frame images, if f=0, then adjacent two frame images were the overlapping e time, as △≤1/2 e(≈ 1/32 second) and f
0 o'clock, because persistance of human vision, adjacent two frame image overlaps formed stereo visual effect, and again because of persistance of human vision, video is a continuously active, and this is then as the normal activity film.Note, watch gained visual sense image just to coincide together for same frame plane video simultaneously with simple eye watching with eyes, but the visual sense brightness under two kinds of situations may and usually different (for narration convenient, this phenomenon of perusal experiment confirm be called for short true P).So, above-mentioned adjacent two frames from the image of two video cameras because of persistence of vision (in onlooker's video intersection) take place overlapping, though all being onlooker's eyes, its every frame receives simultaneously, but with its every frame of the simple eye reception of onlooker again (because of persistence of vision takes place) thus overlapping-obtain stereo visual effect, and be unique stereo visual effect-the visual sense effect just the same.Details are as follows can only to obtain the reason of unique stereo visual effect, as figure (2):
From adjacent two frame image a, the b of two video cameras forms onlooker's visual sense for onlooker's eyes receive, (image frame a and b be only promising onlooker's left eye C respectively for total nine kinds of different situations of I-IX
1, right eye C
2Look respectively and see and C
1C
2Look simultaneously and see three kinds of possibilities, so add up to the different possibilities of 3 * 3=9 kind), the situation I obtains stereo visual effect.Suppose that the situation II obtains differing from the non-stereoacuity of I, so, it has just violated true P, because according to true P, the I II should obtain same visual sense (stereo visual effect or non-), and just both have the difference of visual sense brightness aspect.In like manner, suppose that the situation III obtains differing from the non-stereoacuity of II, so, it has just violated true P, because according to true P, the II III should obtain same visual sense (stereo visual effect or non-), and just both have the difference of visual sense brightness.In like manner, suppose that the situation III obtains differing from the non-stereoacuity of II, so, it has just violated true P, because according to true P, the II III should obtain same visual sense (stereo visual effect or non-), just both have the difference of visual sense brightness, therefore, situation I II III must obtain same stereo visual effect, and just they may each have difference aspect the visual sense brightness.In like manner, suppose that situation IV-IX obtains differing from the non-stereoacuity of I or II or III, so, it has just violated true P, because according to true P, I or II or III and IV (or V or VI or VII or VIII or IX) should obtain same visual sense (stereo visual effect or non-), and just they may each have difference aspect the visual sense brightness.Therefore, I II III IV V VI VII VIII IX must obtain same stereo visual effect, and just they may each have difference aspect the visual sense brightness.The method of above-mentioned acquisition three-dimensional moving image is called left and right sides image frame alternative method.(as above state, it is) △≤1/2 e(≈ 1/32 second) and f the condition that left and right sides image frame alternative method can obtain clear unique stereo visual effect is: one, about the condition of the specific over-over mode of image frame:
0, at this moment, because of persistance of human vision, the video that is no less than 32 frames in the per second is to occur continuously, and every adjacent two frame image overlaps
E ≈ 1/16 second, promptly adjacent two frame image overlaps together, alternately each unique stereo visual effect image occurs once being overlapped into from images of two video cameras for this, and when being no less than 16 frames in so coherent stereo visual effect image per second, formation continuously active image.Only besides aspect condition is about specific shooting situation and specific condition two of reflecting the situation of drilling: require to satisfy the clear condition of looking, please see Figure (3).Scenery is taken by left and right cameras and is obtained image frame a and b respectively, when if they alternately are connected in same coherent film, image frame a and b are d in the distance of left and right directions, drill when being shown in screen through reflecting, image frame a and b are D in the distance of left and right directions on the screen, D is with specifically reflecting the situation of drilling (for three-dimensional film, reflecting the situation of drilling comprises: employed projector, the distance h of d and projector and screen, for three-dimensional video, reflecting the situation of drilling comprises: employed videoplaver and picture tube thereof, d and picture tube beam source and fluoroscopic distance h) and different.The image frame distance is R on onlooker's eyes and the screen, and the distance of taking main scenery and left and right cameras optical center line is r, then just thinks to satisfy
The onlooker could and must obtain clearly (unique) stereo visual effect in reflecting when drilling, just can take the photograph corresponding to the image of left and right sides eyes observation because the distance that is equivalent to the left and right cameras camera lens space of eyes must equal the average distance of human eyes (this average distance grow up people be 60-65mm), (1) median of the distance of left and right cameras optical center is l in, make l=62.5mm, then because of (l-p, l+p)=(60,65)=(62.5-p, 62.5+p) mm, get p=2.5mm, (1) (γ-q in, γ+r) be that (the two video camera depth of field are taken as identical for the depth of field of shooting function shooting clear image frame, this then is obvious convenient shooting, reflect the latent condition of drilling of establishing, unless special necessity is not done bright stating usually.So), relational expression
The angle that provides
Two video cameras must be taken the angle α scope of image frame a and b clearly that obtains about (≤180 °, 〉=0 °) had indicated.When reflecting when drilling, the image frame a of left and right sides interval D and b look for onlooker's eyes and see and mirror in the brain that onlooker's eyes are to watch at the R place apart from them on the screen, and the sight angle that left eye is opened left and right sides image frame a, b distance D at interval is β
1, the visual angle that right eye is opened left and right sides image frame a, b distance D at interval is β
2, because common R〉〉 D, so, common β
1≈ β
2, and
We know that already when the shooting situation, left side photography picture frame a and right photography picture frame b are with respect to the angle of scenery
(≤180 °, 〉=0 °) time image frame a, b just just all be clearly, according to the reversible reason of light, if this clearly image frame a, b(in that to reflect the situation of drilling be image frame a, b on the screen) directive onlooker eyes (according to aforementioned left and right sides image frame alternative method) are in order to do obtaining clearly (unique) stereo visual effect conversely, just think that then this image frame a, b(are in that to reflect the situation of drilling be image frame a, b on the screen) visual angle that forms with onlooker's eyes
The time, onlooker's eyes just just can obtain clearly (unique) stereo visual effect, because at this time from image frame a, b(clearly in that to reflect the situation of drilling be image frame a, b on the screen) oppositely penetrate the light that comes and just just in time form just like the clear solid image that sends at the beginning of the scenery at onlooker's eyes, this clear solid image is watched for onlooker's eyes must form clearly (unique) stereo visual effect.Left and right sides image frame onlooker's video intersection overlapping (can) to obtain stereo visual effect also relevant with the individual character of looking association with onlooker's visual experience, two same frames replace left and right sides image and may form stereo visual effect some onlooker, then can't form stereo visual effect other onlookers, but, this is very little by onlooker's visual experience with the difference that the individual character of looking association causes, can ignore in present approximate calculation (R〉〉 D situation) lining.As R〉〉 during D, condition
Can transcription become (1) promptly
Formula (2) or its reformulations (1) (3) are called the clear condition of looking.Under the situation that condition one satisfies, when the clear condition of looking satisfied again, the onlooker watched reflecting and drills alternately left and right sides image frame a, the b ability on the screen and must obtain clearly (unique) three-dimensional visual image.
Example: with mm is long measure, works as l
± p=(60,65), r=∞, q=4000, γ=5000, D=65 then by (3), satisfies the clear condition of looking
R=(65 (5000-4000,5000+ ∞))/((60,65))=(1000, ∞)
This speech, only distance was reflected and was drilled screen and be not less than 1 meter onlooker and can and must look and see clearly (unique) three-dimensional visual image this moment.
For general projector and videoplaver, D all is respectively monotonic increase relation or proportional relation about d, h, because h is limited to usually to reflect and is drilled the place size, and must fix in drilling in reflecting because of projector and screen (for three-dimensional video, h is limited to the picture tube size of videoplaver), l again
± p=(60,65) mm, so, according to (3), regulate d, make D adapt to concrete the concrete of main scape situation of taking
And change, reflect the R that drills the onlooker on all seats in the place and all meet the clear condition of looking thereby make, be that we make when linking up film and should accomplish.We can reach this requirement with the specific synthesis step of right photography picture frame on a coherent film by the left side picture frame of photographing, but preferably rely on the servo-actuated of congenerous
And regulate d, make D, R meet the clear two-tube shooting special plane of looking condition and make so coherent film.
Drill on the screen image frame size hour when reflecting, D is very little, because the r relevant with the left and right cameras depth of field is very big usually, so, by (3), the lower limit of R is less, and the upper limit is then very big, therefore, the little TV of picture display screen size, according to left and right sides image frame alternative method, we are easy to see clearly (unique) three-dimensional visual image in vast R scope, and this is the at first reason of application success on stereoscopic TV is made of left and right sides image frame alternative method.But left and right sides image frame alternative method is used for the research of three-dimensional film to begin more early, at that time, owing to do not recognize that clearly (unique) stereo visual effect can only occur clear looking under the condition, do not know what the clear condition of looking is yet, the film of being tested reflects the situation of the drilling h of (at the cinema), D is all excessive, make that all meeting the clear R that looks condition for the onlooker on all seats is difficult to realize under this at the cinema place, this is the main cause that former people abandon making with the left and right sides image frame alternative method three-dimensional film, now through tight calculating, derive and the embodiment design, we have confirmed this method again.In fact, the stereoscopic TV of large-screen or three-dimensional video all exist as three-dimensional film make must meet clear problem of looking condition running into.
More than research all supposition reflect and drill the required time k of screen reflection image frame
1(for reflecting curtain), or fluorescence residence time k
2(for phosphor screen) throws duration than that image frame and can ignore, this is the investigation and the calculating of obvious convenient theory then, and now actual reflecting of using drilled screen (as the phosphor screen of cloth curtain, aluminum screen, television set or video tape recorder) and also can both be closed this requirement of symbol under the situation of drilling really in common reflecting.
Obtain the three-dimensional film of the research and design making of three-dimensional active images according to above-mentioned left and right sides image frame alternative method, three-dimensional video is described below: one, the film image that obtains with the twin camera alternating camera as eyes is made respective quadrature for connection, make per second reflect drill g(〉=32) frame
(notes)Coherent film, with specific film-making step, make left side photography picture frame and right photography picture frame between left and right apart from the variation of the main scape situation of the corresponding shooting of d with reflect the situation of drilling and meet the clear condition of looking all the time, but or take main scape situation with the alternating camera servo-actuated and regulate d with reflecting the situation of drilling, the two-tube shooting special plane of congenerous that the clear condition of looking is satisfied is all the time produced this coherent film, in meeting the clear place of looking condition, on the cinematographic projector of per second projection g frame, show, promptly obtain the generation three-dimensional film image of unique stereo visual effect clearly.Two, as two outputs of the double TV television camera tube of eyes through one can the main scape situation of corresponding shooting variation regulate with reflecting the situation of drilling left side photography picture frame and right photography picture frame between left and right apart from d, make the clear kine bias moving device that condition satisfies all the time of looking, alternately open and close this two output g(〉=32 through a per second again) inferior
(notes)Electronic switch (or earlier through electronic switch, again through the kine bias moving device), and then import existing recording apparatus, the coherent video film that is write down reflects and drills in the place meeting the clear video recording of looking condition, speed projection with per second g frame image promptly obtains the unique clearly stereo visual effect of generation
(notes)The three-dimensional video image.Referring to figure (4).According to such three-dimensional video design, video film is that unified making the and dividing failed in each user's videoplaver if link up, so, just must according to the size of shown image frame (thereby, the size of d and the size of display screen) distinguish different (size) shelves and make the video film that links up, the user chooses corresponding (the clear condition of looking that meets its video shows) according to the shelves under the display screen size of own all videoplavers, and the video film input links up.The mechanism of the d of the coherent video film imported if videoplaver self extra gear changes so, also can use the unified standard video film that links up.By comparison, a kind of way in back is not as good as preceding a kind of easy, in addition existing video tape recorder thousands upon thousands, and it is easier said than done to reequip one by one, but new from now on video tape recorder design, produces and can consider to adopt the back and plant design.
The present invention and existing method relatively have following improvement:
(1) left and right sides image frame alternative method can obtain to have the active images of unique stereo visual effect clearly certainly, and provided and to have obtained the complete condition of the active images of unique stereo visual effect clearly, though the existing fact of this condition foundation obtains through derivation, complicated like this condition extremely difficulty directly obtains from the experimental data conclusion.
(2) further pointed out to make the new method of three-dimensional film and the method for making three-dimensional video in view of the above, the advantage of this method:
(ⅰ) needn't watch by wearing spectacles.
(ⅱ) screen that needn't be special (referring to United States Patent (USP) 4309074).
(ⅲ) can be used for the display screen of various sizes and the three-dimensional film and the three-dimensional video in place makes.
(ⅳ) manufacture method can be rated as easy.
(notes) according to the motion picture projection experience, per second 24 frames to reflect the play sense of continuity good, speed is not too high again, so get g=24 * 2=48 usually.
Stereoscopic TV
Two television camera tubes are just like eyes, (black and white or colour) shooting for consecutive image is that two pipes hocket, between shooting f(〉=0), each television camera tube branch is taken the photograph and is obtained blank spaces △+2f, continue the interrupted image of △, the signal of telecommunication process circuit of camera system will correspondingly alternately couple together by f uniformly-spaced from the picture intelligence of two television camera tubes and do the transmission and the reception that link up.Referring to figure (1).
The moment of supposing onlooker's eye nethike embrane reception video signal of broadcasting is t, is d from the eye nethike embrane to optic chiasma top video intersection neurotransmission signal time, and the persistence of vision time is e(≈ 1/16 second), so, following lasting interval will intermittently be received in video intersection
Signal.When △≤e, every frame image continues:
(t+d, t+ △+d+e) the first frame image duration
(t+d+ △+f, t+d+2 △+e+f) the second frame video duration
……
Therefore, when △≤e, onlooker's video intersection will intermittently alternately obtain the signal from two (television camera tubes) eye, and at this moment, f-e is exactly the image blanking time of onlooker's video intersection, thereby, if f=e is nonseptate between the then adjacent two frame images, if f=0, then adjacent two frame images were the overlapping e time, as △ ≈ 1/2 e(≈ 1/32 second) and f
0 o'clock, because persistance of human vision, adjacent two frame image overlaps formed stereo visual effect, and again because of persistance of human vision, image is a continuously active, and this is then as the normal activity film.Note, watch gained visual sense image just to coincide together for same frame flat image simultaneously with simple eye watching with eyes, but the visual sense brightness under two kinds of situations may and usually different (for narration convenient, this the phenomenon of perusal experiment confirm be called for short true P), so, above-mentioned adjacent two frames from the image of two television camera tubes because of persistence of vision (in onlooker's video intersection) take place overlapping, though all being onlooker's eyes, its every frame receives simultaneously, but with its every frame of the simple eye reception of onlooker again (because of persistence of vision takes place) thus overlapping-obtain stereo visual effect, and be unique stereo visual effect-the visual sense effect just the same, details are as follows can only to obtain the reason of unique stereo visual effect, as figure (2), adjacent two frame image a from two television camera tubes, b forms onlooker's visual sense for onlooker's eyes receive, total nine kinds of different situations of I-IX (each only promising onlooker's left eye C of image frame a and b
1, right eye C
2Look respectively and see and C
1C
2Look simultaneously and see three kinds of possibilities, so add up to the different possibilities of 3 * 3=9 kind), the situation I obtains stereo visual effect, suppose that the situation II obtains differing from the non-stereoacuity of I, so, it has just violated true P, because according to true P, the I II should obtain same visual sense (stereo visual effect or non-), and just both have the difference of visual sense brightness aspect.In like manner, suppose that the situation III obtains differing from the non-stereoacuity of II, so, it has just violated true P, because according to true P, the II III should obtain same visual sense (stereo visual effect or non-), just both have the difference of visual sense brightness aspect, therefore, situation I II III must obtain same stereo visual effect, and just they may each have difference aspect the visual sense brightness ...In like manner, suppose that situation IV-IX obtains differing from the non-stereoacuity of I or II or III, so, it has just violated true P, because according to true P, I or II or III and IV (or V or VI or VII or VIII or IX) should obtain same visual sense (stereo visual effect or non-), and just they may each have difference aspect the visual sense brightness.Therefore, I II III IV V VI VII VIII IX must obtain same stereo visual effect, and just they may each have difference aspect the visual sense brightness.The method of the three-dimensional active images of above-mentioned acquisition is called left and right sides image frame alternative method.(as above state, it is) △≤1/2 e(≈ 1/32 second) and f the condition that left and right sides image frame alternative method can obtain clear unique stereo visual effect is: one, about the condition of the specific over-over mode of image frame:
0, at this moment, because of persistance of human vision, the image that is no less than 32 frames in the per second is to occur continuously, and every adjacent two frame image overlaps
E ≈ 1/16 second, be adjacent two frame image overlaps together, unique stereo visual effect image alternately respectively appears once being overlapped in this image from two television camera tubes, and when being no less than 16 frames in so coherent stereo visual effect image per second, forms the continuously active image.Only besides aspect condition is about specific shooting situation and specific condition two of reflecting the situation of drilling: require to satisfy the clear condition of looking, please see Figure (3).Scenery is taken by left and right sides television camera tube and is obtained image frame a and b respectively, when if they alternately are connected in same coherent film, image frame a and b are d in the distance of left and right directions, drill when being shown in screen through reflecting, image frame a and b are D in the distance of left and right directions on the screen, D is different with specifically reflecting the situation of drilling (employed television set and picture tube thereof, d and picture tube beam source are to fluoroscopic distance h).The image frame distance is R on onlooker's eyes and the screen, and the distance of taking main scenery and television camera tube optical center, left and right sides line is r, then just thinks to satisfy
The onlooker could and must obtain clearly (unique) stereo visual effect in reflecting when drilling.Just can take the photograph corresponding to the image of left and right sides eyes observation because the television camera tube camera lens space, the left and right sides that is equivalent to eyes must equal the average distance of human eyes (this average distance grow up people be 60-65), (1) median of the distance of television camera tube optical center, the left and right sides is l in, make l=62.5mm, then because of (l-p, l+p)=(60,65)=(62.5-p, 62.5+p) mm gets p=2.5mm.(1) in (γ-q, γ+r) be television camera tube can shooting clear image frame the depth of field (the two television camera tube depth of field are taken as identical, this then for obvious convenient shooting, reflect the latent condition of drilling of establishing, unless special necessity is not done bright stating usually.), so, relational expression
The angle that provides
Two television camera tubes must be taken the angle α scope of image frame a and b clearly that obtains about (≤180 °, 〉=0 °) had indicated.When reflecting when drilling, the image frame a of left and right sides interval D and b look for onlooker's eyes and see and mirror in the brain on the screen, and onlooker's eyes are to watch apart from their R places, and the visual angle that left eye is opened left and right sides image frame a, b distance D at interval is β
1, the visual angle that right eye is opened left and right sides image frame a, b distance D at interval is β
2, because common R〉〉 D, so, common β
1≈ β
2, and
We know that already when the shooting situation, left side photography picture frame a and right photography picture frame b are with respect to the angle of scenery
(≤180 °, 〉=0 °) time, image frame a, b just just all are clearly, according to the reversible reason of light, if this clearly image frame a, b(in that to reflect the situation of drilling be image frame a, b on the screen) directive onlooker eyes (according to aforementioned left and right sides image frame alternative method) are in order to do obtaining clearly (unique) stereo visual effect conversely, just think that then this image frame a, b(are in that to reflect the situation of drilling be image frame a, b on the screen) and with looking that onlooker's eyes form
The time, onlooker's eyes just just can obtain clearly (unique) stereo visual effect, because at this time from image frame a, b(clearly in that to reflect the situation of drilling be image frame a, b on the screen) oppositely penetrate the light that comes and just just in time form just like the clear solid image that sends at the beginning of the scenery at onlooker's eyes, this clear solid image is watched for onlooker's eyes must form clearly (unique) stereo visual effect.Left and right sides image frame onlooker's image intersection overlapping (can) to obtain stereo visual effect also relevant with the individual character of looking association with onlooker's visual experience, two same frames replace left and right sides image and may form stereo visual effect some onlooker, then can't form stereo visual effect other onlookers, but, this is very little by onlooker's visual experience with the difference that the individual character of looking association causes, can ignore in present approximate calculation (R〉〉 D situation) lining, as R〉during D, condition
Formula (2) or its reformulations (1) (3) are called the clear condition of looking, under the situation that condition one satisfies, when the clear condition of looking satisfied again, the onlooker watched reflecting and drills alternately left and right sides image frame a, the b ability on the screen and must obtain clearly (unique) three-dimensional visual image.
Example: with mm is long measure, works as l
± p=(60,65), r=∞, q=4000, γ=5000, D=65 then by (3), satisfies the clear condition of looking
R=(65 (5000-4000,5000+ ∞))/((60,65))=(1000, ∞)
This speech, only distance was reflected and was drilled screen and be not less than 1 meter onlooker and can and must look and see clearly (unique) three-dimensional visual image this moment.
For general television set and picture tube thereof, D all is respectively monotonic increase relation or proportional relation about d, h, because h is limited to the picture tube size of television set, l again
± p=(60,65) mm, so, according to (3), regulate d and make D adapt to concrete the concrete of main scape situation of taking
And change, reflect the R that drills the onlooker on all seats in the place and all meet the clear condition of looking thereby make, be that we make when stereoscopic TV links up film and should accomplish.
Drill on the screen image frame size hour when reflecting, D is very little, because the r relevant with the left and right sides television camera tube depth of field is very big usually, so by (3), the lower limit of R is less, the upper limit is then very big.Therefore, the little TV of picture display screen size, according to left and right sides image frame alternative method, we are easy to see clearly (unique) three-dimensional visual image in vast R scope, and this is the at first reason of application success on stereoscopic TV is made of left and right sides image frame alternative method.But left and right sides image frame alternative method is used for the research of three-dimensional film to begin more early, at that time, owing to do not recognize that clearly (unique) stereo visual effect can only occur clear looking under the condition.Do not know what the clear condition of looking is yet, it is all excessive (for three-dimensional film that the film of being tested reflects the situation of the drilling h of (at the cinema), D, h is meant the distance of projector and screen), make that all meeting the clear R that looks condition for the onlooker on all seats is difficult to realize under this at the cinema place, this is the main cause that the past people abandon making with the left and right sides image frame alternative method three-dimensional film.Through tight calculating, derivation and embodiment design, we have confirmed this method again now.In fact, the stereoscopic TV of large-screen or three-dimensional video all exist as three-dimensional film make must meet clear problem of looking condition running into.
More than research all supposition reflect the fluoroscopic fluorescence residence time k that drills screen-television set and can ignore than that image frame projection duration.This is the investigation and the calculating of obvious convenient theory then, and now the phosphor screen of television set also can both conform with this requirement really reflecting usually under the situation of drilling.
Obtaining the stereoscopic TV uncle that the research and design of three-dimensional active images makes according to above-mentioned left and right sides image frame alternative method is set forth in down: as two outputs of the double TV television camera tube of eyes through one can the main scape situation of corresponding shooting variation with reflect the situation of drilling regulate left side photography picture frame and right photography picture frame between left and right apart from d, make the clear satisfied all the time kine bias moving device of condition of looking.Alternately open and close this two output g(〉=32 through a per second again) inferior
(notes)Electronic switch (or earlier through electronic switch again through the kine bias moving device), and then import existing television playing device, the coherent telefilm of being play is that television set receives, and reflect and drill in the place meeting the clear TV of looking condition, speed projection with per second g frame image promptly obtains the unique clearly three-dimensional tv images of generation.Referring to figure (5).According to such stereoscopic TV design, coherent telefilm is that unified making the and dividing failed in each user's television set, therefore, must according to the size of the shown image frame of television set (thereby, the size of d and the size of display screen) distinguish different (size) shelves and make the telefilm that links up, the user chooses corresponding (the clear condition of looking that meets its television projection) telefilm that links up according to the shelves under the display screen size of own all television sets and watches.The mechanism of the d of the coherent telefilm that received if television set self extra gear changes so, also can only make and play the unified standard telefilm that links up.By comparison, a kind of way in back is not as preceding a kind of suitable now of (television set) situation, because present most users' television set is to be attributable to (9,26) very little one grade small screen TV machine (minitube, large-screen receiver and projection TV set are few for number), the coherent telefilm that TV station make to be fit to this grade size is play and just can be satisfied most users and watch and required, in addition existing television set thousands upon thousands, it is easier said than done to reequip one by one, also uneconomical, but new from now on television set designs, produces and should consider to adopt back kind design.
The present invention and existing method relatively have following improvement:
(1) certainly left and right sides image frame alternative method can obtain to have the active images of unique stereo visual effect clearly, and has provided and must obtain the complete condition of the active images of unique stereo visual effect clearly.Though the existing fact of this condition foundation obtains through derivation, complicated like this condition extremely difficulty directly obtains from the experimental data conclusion.
(2) further pointed out to make the new method of stereoscopic TV in view of the above, the advantage of this method is:
