This invention assembly also comprises a special software, as related 13 in the accompanying drawing 5, and the inductor 15 of the automatic range on or several width of cloth special eyeglasses 14, the digital camera main body 1.In accompanying drawing 3,18 be human body or the object that to take.
Here the simple explanation ultimate principle of three-dimensional imaging once, people's eyes are when watching attentively object, because the distance between left eye and the pupil of right eye, be approximately 5cm, left eye and right eye will produce the image of the identical viewpoint of different visual angles to an object (same viewpoint in other words conj.or perhaps), these two different visual image signals, the acceptance of process brain and processing have just formed the stereoscopic visual effect of a three-dimensional, just we the image of the actual object of seeing, so, form the effect of the image of a solid, will allow two eyes receive the image of the identical viewpoint of different visual angles of object simultaneously.The related ultimate principle of this invention also is like this, the camera lens of digital camera is to be divided into two complete parts, be exactly right lens assembly 2 and left lens assembly 3, two eyes that are equivalent to the people, two partly are approximately 5cm apart between the center, suitable with the distance between people's the pupil, the people is when seeing the object of different distance, and eyes can be done automatic adjustment, makes sight be focused at the centre of object, form a center viewpoint, when infinity, two sight is promptly near two parallel lines states, and under very near situation, will be converted into a mid point, such as the line etc. of under very near situation, threading a needle, the viewpoint of two eyes can be focused at very near a bit, so, angle between two eyes is constantly along with the distance between watching attentively object and the people changes, and this fundamemtal phenomena as shown in Figure 3.
The lens assembly design of this invention is just for corresponding this a kind of situation, in digital camera body 1, be provided with the lens assembly of two independences and interlock, right lens assembly 2 and left lens assembly 3, in the time will taking object far away, the optical center axis is less with the angle of being watched attentively that directional ray became, when infinity, can ignore and see zero as, promptly two parallel, when taking nearer object, camera lens is bigger with the angle of being watched attentively that direction became, as the α angle in the accompanying drawing 2, if at this moment the center with two camera lenses and the shot object of being wanted respectively is the summit, can constitute a triangle by these 3 so, the drift angle of this triangle also is different so, as shown in Figure 3, β angle when taking distant objects must be the β angle when taking near objects, and the geometric relationship that β=2 α are arranged, like this, as long as the definite object point that will take, and the center line of camera lens is converged on this point, take, so captured image just is equivalent to people's a left side, the effect of the image that right eye is seen respectively, the method that the viewpoint of two camera lenses is assembled about making in the present invention is to be set in can certain limit in the horizontal direction two camera lenses rotatable, and be provided with a right analyzer 4 at the axle center of right lens assembly 2 upside and camera lens axis parallel, also be provided with a left analyzer 5 at the axle center of left lens assembly 3 upside with the camera lens axis parallel, right, left side analyzer 4,5 can launch visible coloured hot spot or other detectable signal, and project object surfaces, emission is red hot spot in the present embodiment, this hot spot line promptly is equivalent to the central axis of two lens assemblies, like this, when manually rotary handle 12 is regulated angle lens, photographer can clearly observe the convergence situation of two camera lenses, if an object is taken, be focused at just passable together at the body surface of place shooting as long as be adjusted to two hot spots.Certainly, if want to do further adjusting to obtaining different stereoeffects, proceed to oneself satisfied till.
Adjusting about visual angle and viewpoint, also can adopt automatic range to regulate, automatically calculate the angle that lens assembly should rotate, therefore, on digital camera main body 1, also has an inductor 15, and motor 16, processor 17, inductor 15 can be an infrared distance measurement, supersonic sounding and other distance measuring method, can obtain the parameter about the camera and the distance between the shot object of wanting of certain precision, when taking, can measure object distance by the inductor 15 of automatic range, and resulting parameter reached camera inner treater 17, processor 17 can draw distance parameter, and provides the angle parameters needed of the required rotation of camera lens, driving corresponding motor 16 rotations goes driving mechanism to finish the rotation of lens assembly, rotate to suitable angle and get final product, can finish the adjusting at visual angle automatically like this, its principle of work process flow diagram as shown in Figure 7.
After regulating viewpoint and visual angle, just can take, because two lens assemblies are interlocks, and be same shutter, so can take down two width of cloth images of the identical viewpoint different visual angles of synchronization, this is two width of cloth images by the identical viewpoint synchronization of different visual angles that is obtained respectively by right lens assembly 2 and left lens assembly 3, directly two width of cloth images by the same object that digital camera obtained also are not to observe directly three-dimensional image, also to can obtain stereo-picture true to nature through handling, also preserve through transferring to computer by the image that above-mentioned digital camera obtained, as JPG, BMP, GIF or other picture format, see that stereo-picture also will observe through the processing of software and with special glasses, here software is done an explanation, the software supporting with this digital camera is a kind of image processing software, be to be used for handling the image that the present invention obtains specially, we know, the image of the identical viewpoint of different visual angles of the same object that is obtained in front, also must send into corresponding right and left eyes respectively and not disturb the reproduction that just can realize stereo-picture mutually, in other words, to send into left eye to the image that left lens assembly 3 is obtained, the image that right lens assembly 2 is obtained is sent into right eye, and left eye and right eye mutual interference and keep separately image mutually, so just can realize the reproduction of stereo-picture, in the present invention, realization is sent into the image of left and right sides respectively in the eyes of the left and right sides and is gone, two kinds of methods can have been adopted respectively, a kind of is the complementary color method, another kind is mutual method, the ultimate principle of complementary color method is, by software the image that is obtained being added colour filter handles, respectively in addition different Transparent color, and two Transparent color are complementary color each other, for example on the image in the left side that left lens assembly 3 is obtained, add red Transparent color, on the image right that right lens assembly 2 is obtained, add the green transparent look, so, when the observer goes to observe image with the transparent glasses of corresponding color respectively again, just can see different effects, such as go to observe with red transparent glasses, just be merely able to see the picture signal in left side substantially, if when going to observe with the glasses of green transparent, just be merely able to see the picture signal on right side basically, if we added two width of cloth image overlay of crossing colour filter above being incited somebody to action by software, initial point correspondence during stack, and with corresponding left side is red transparent, and the right side is the coloured spectacles of green transparent when going to observe, because left eye is only to see the image of the object that left lens assembly 3 is obtained, right eye is the image to see that right lens assembly 2 is obtained only, here just formed the sensation of a stereo-picture, feeling that just color is abundant inadequately, is can lose some color generation because cross goggles with color filter here.Here related eyes are special both sides glasses of complementary color each other.
Except above-mentioned complementary color method and coloured spectacles, can also realize with another method, can make effect more true to nature.We know, people's eyes have a characteristic, be exactly " persistence of vision ", for the visual signal of being seen, even blackout, in people's eyes, also can retain the time of about 1/12nd to ten sixth second, if the image of taking was continuously play with the proper speed time, promptly can form the continuous effect of picture, film is just based on this principle, we can utilize this characteristics fully, if the image that is obtained the same viewpoint of same object different visual angles by digital camera is shown, the image that shows a side wherein earlier, deliver in the eyes of a corresponding side, and shelter from the eyes of an other side, in the time that does not also have to disappear in visual persistence effect, time was less than one of 16 seconds, closing this width of cloth image shows, and then the image that shows opposite side, current only to allow the eyes of opposite side see this width of cloth image, allowing the eyes of a side noted earlier be blocked becomes and can not see, this has in fact accomplished to allow the eyes of homonymy not see the image at respective side visual angle, so just can form the sensation of stereo-picture, for example, that is to say, can be in a time cycle, can on display screen, show image earlier by the right lens assembly 2 same viewpoint in visual angle, right side of obtaining, the demonstration time can be set at about demonstration sixtieth second, a refresh cycle that just is equivalent to general computer monitor, in this time period, left eye is blocked, only allow observer's right eye see the image that this shows, second sixtieth second, the image that demonstration is obtained by left lens assembly 3, it also is the preceding piece image same position that is presented on the screen, the length of demonstration time is the same with the last width of cloth, it also is sixtieth second, in this time period, observer's right eye is blocked, only to allow observer's left eye see the image that this shows, because the effect of persistence of vision, though in fact observer's right eye does not see any image in this time period, but still can feel to have the signal of image to exist, and left eye also can be observed the picture signal of being obtained by left lens assembly 3 that shows on screen, spent this time period, promptly enter the 3rd sixtieth of next cycle second, the image that shows the right side again, close the glasses in left side, promptly repeat above-mentioned process again repeatedly, observer's left eye will be blocked, but because the effect of persistence of vision, still can feel picture signal, so continuous repetition, so what observer's right and left eyes was accepted respectively is the picture signal of the same viewpoint in corresponding visual angle, do not produce mutually yet and disturb, be continuous on visual sense feeling, formed the 3-D view of lively solid, when software carries out the image transitions demonstration, can produce a synchronizing signal simultaneously, this provide to supporting be used for specially observe the glasses of image.
It is related here that what be used for blocking right and left eyes respectively is a kind of glasses, what adopted in the present embodiment is the liquid crystal light valve glasses, its two eyeglasses are independently, can carry out opening and closing respectively in the different time, when the liquid crystal light valve eyes are opened, present transparent state, when the liquid crystal light valve eyes are closed, what present is dark state, and when the left side eyeglass open and the time, the eyeglass on right side is closed, equally, when the right side eyeglass is opened, the left side eyeglass is closed, like this, in software in the image transitions, or in the specific time, can provide a switching signal by software, reach this glasses by connecting line or wireless signal without any other additional integrated circuit board, here connecting line can be USB, standard interfaces such as PS/2, connecting line, also can the audio output signal line, the wireless signal mode can be an infrared mode, also can be the RF mode, finish corresponding automatic switching, promptly when display screen show be the picture signal of the same viewpoint in visual angle, left side the time, open the eyeglass in left side simultaneously, and the eyeglass on right side closed, when display screen show be the picture signal of the same viewpoint in visual angle, right side the time, open the eyeglass on right side, and the eyeglass in left side is closed simultaneously, so constantly repeat, just can form complete sum continuous images signal, because eye storage characteristic, the observer just can observe vividly really stereo-picture, and without any color lose.
The workflow of this invention as shown in Figure 6, at first choose the object 18 that to take, the manual adjustment right side, left side lens assembly 2, analyzer 4 on 3,5, the hot spot that they are sent converges at a bit, it is the surface of object 18, like this, the viewpoint of two camera lenses is just assembled in a bit, perhaps measure object distance by the inductor 15 of automatic range, and calculate the angle of distance and the required rotation of camera lens by the camera inner treater, press the shutter of digital camera then, the image of the same viewpoint of picked-up object left and right sides different visual angles, two width of cloth images with the same viewpoint of different visual angles of the same object that obtained are transferred to computer then, in computer, can select the different modes of watching in the software interface of special use, a kind of is interactive, a kind of is the complementary color formula, wherein interactive mode is that the cycle shows in turn fast on screen for the image of the identical viewpoint of two width of cloth different visual angles that will be obtained, when showing conversion, can produce a synchronizing signal, be transferred to corresponding liquid crystal glasses, the eyeglass of glasses is under the effect of synchronizing signal, the corresponding shown image of left and right sides eyeglass takes turns opening and closing, like this, when display screen show be the image of the same viewpoint in visual angle, left side the time, observer's left eye just can be seen the image of the same viewpoint in object visual angle, left side, and right eye has been blocked, when display screen show be the image of the same viewpoint in visual angle, right side the time, observer's the image that can just can see the same viewpoint in visual angle, object right side, and simultaneously left eye is blocked and has leant on, this is the quick conversion of carrying out in the effective time of persistence of vision, in observer's sensation, promptly formed the sensation of stereo-picture, shown in right side flow process among the figure.The another kind of mode that obtains stereo-picture is the complementary color formula, obtain the image of the same viewpoint of same object different visual angles at computer after, the special software important plan looks like to add colour filter to be handled, promptly two width of cloth images to the same viewpoint of different visual angles increase the Transparent color processing, the left and right sides is added different Transparent color respectively, and complementary color each other, again on the computer screen that two width of cloth image overlay are got up to show, the observer wears the glasses with add complementary color corresponding color, the image that comes observation post to show, because two eyeglasses are complementary color each other, observer's left eye and right eye are merely able to see a corresponding left side respectively, the image on right side be can't see the image of opposite side substantially, watches the sensation that promptly can form stereo-picture like this, just color is incomplete, and the user can select different view modes and glasses to observe stereo-picture.
Above-mentioned method can make ordinary consumer easily obtain and watch three-dimensional image true to nature, and equipment is simple, and is easy to operate, and stereoeffect is strong.
