The specific embodiment
Embodiment of this utility model as shown in Figure 1, in this wear-type vision enhancing system, the support 4 that comprises a spectacle, the leg of spectacles part of not drawing among the figure, can in Fig. 1, load onto the leg of spectacles that stretches out along this place's direction of arrow in the position of label 4 indications during concrete enforcement, can form the spectacle support, corresponding shell structure also can further be set certainly corresponding parts all are contained in inside, constitute the structure of a spectacle.
In the support of this spectacle, two micro-display chips 1 about being equipped with, about two big angle of visual field optical prisms 2 and a stereo-picture control circuit 3.Micro-display chip 1 wherein is an active illuminating, and big 2 light that micro-display chip 1 is sent of angle of visual field optical prism carry out the camber reflection processing and are sent to human eye along right side arrow direction among Fig. 1 again.
Fig. 2 shows the light trend between micro display chip and the optical prism, after the chief ray that is sent by micro-display chip 1 enters optical prism 2, needs just enter human eye 5 through two secondary reflections.Big angle of visual field optical prism 2 wherein has three faces, and first 21 is transmission plane, and it and micro-display chip 1 are faced; Second 22 of big angle of visual field optical prism 2 can reflect the light that imports through first 21, form the 3rd 23 of first reflection and directive; The 3rd 23 is minute surfaces of a plated film, and light forms reflection for the second time again at this, gets back to second 22 again, and penetrates the retina that is sent to human eye 5.
During concrete enforcement, three faces of big angle of visual field optical prism 2 preferably all are curved surfaces, and the designed distance between first 21 of the light-emitting area of micro-display chip 1 and big angle of visual field optical prism 2 can be the 2-3 millimeter, and inclination angle between the two is between the 28-36 degree; The refractive index Nd of big angle of visual field optical prism 2 material therefors is between 1-1.6.
Wherein, the radius of curvature R 3 of second 22 2 to the three 23 of radius of curvature R is big in the big angle of visual field optical prism 2, and for example desirable R2 is 140~180mm, and R3 is 60~80mm.The tangent line angle of 2 surface intersection points is 24 °-45 °, adjusts this angle and can adjust prism thickness and object view size.Adjust the ratio of R3/R2, but the amplification of coarse adjustment image produces the more visual effect of giant-screen.
Preferably use 1, two identical optical prism 2 of two identical micro-display chips.Corresponding schematic block circuit diagram as shown in Figure 3, comprising the stereo-picture control circuit and about two micro-display chips.At the micro-display chip internal row, column depositor and row, column driver are arranged, be used to drive the RGB lattice array; The micro-display chip internal is integrated RGB reservoir, RGB sequential control circuit and control logic circuit.Comprise MCU image control circuit, VGA/AV interface etc. in the stereo-picture control circuit.The stereo-picture control circuit provides the logic control signal of various needs for the micro-display chip, for example, frame synchronization, row synchronously, pixel effectively, brilliance control, interrupt signal, enable signal, colour saturation control and scan mode, picture position, the three-dimensional frame gating signal of 3D or the like.Also can set up the sound input interface in the stereo-picture control circuit, and play sound by miniature loudspeaker.
During concrete enforcement, except that using above-mentioned VGA/AV video input interface, also can on support, install the memorizer that is used for the storing stereoscopic video data, and the mini-broadcast device that is used for the stereo video data of memorizer is play and is sent to the stereo-picture control circuit.
Utilize above-mentioned wear-type vision to strengthen system, can perform physical exercise to human eye, correlation technique may further comprise the steps:
(S1) play stereo video data and stereo video signals is sent to control circuit;
(S2) stereo-picture control circuit stereoscopic video signal handle and decompose left and right sides two-path video signal repeated transmission and deliver to about two micro-display chips;
(S3) two micro-display chips show that respectively left and right sides two-path video signal constitutes stereo-picture about, with the attention that demonstrates the bootable person of wearing make its optic centre do distance, about, up and down, the stereo-picture of aggregate motion such as circumference.
Among the embodiment of the present utility model, as shown in Figure 4, the stereo video data in the step (S1) is left eye 320 * 480 color image datas, right eye 320 * 480 color image datas; In step (S2), generate the left and right sides two-path video signal of left eye 640 * 480 color image datas, right eye 640 * 480 color image datas by the interpolation conversion process by the stereo-picture control circuit.Again as shown in Figure 3, and two micro-display chips about delivering to respectively, small image on the micro-display chip respectively by about two big angle of visual field optical prisms amplify, and imaging on the virtual focusing plane makes and wears vision and strengthen system person and can see stereo-picture by prism.
Wherein, stereo video data in the step (S1) can be produced generation to same true or virtual image by two true or virtual video cameras, wherein both by changing two true or the spacing of virtual video camera and the separating degrees that angle is adjusted stereo-picture, realize the continuous variation of vertical distance of stereo-picture again by the continuous variation of angle, two true or virtual video cameras by about synchronously, up and down, aggregate motion such as circumference realizes the variation of optic centre.As shown in Figure 7, can and then change shooting focal length L by the angle theta that changes two video cameras 51,52, thereby change virtual vision center 53; By changing the interval S of two video cameras, can satisfy and the different human needs of undergoing training of adaptation interpupillary distance; Simultaneously, S and θ change the separating degree that also can change stereo-picture.
In this utility model,, also can realize the variation of optic centre by the motion of moving object in the background image for the stereo video data of step (S1).
Among another embodiment of the present utility model, as shown in Figure 5, the stereo video data in the step (S1) is left eye 640 * 480 color image datas, right eye 640 * 480 color image datas; In rapid (S2), handle the left and right sides two-path video signal that generates left eye 640 * 480 color image datas, right eye 640 * 480 color image datas by componentwise by the stereo-picture control circuit.
Among another embodiment of the present utility model, as shown in Figure 6, the stereo video data in the step (S1) is left eye 800 * 640 color image datas, right eye 800 * 640 color image datas; In step (S2), handle the left and right sides two-path video signal that generates left eye 800 * 640 color image datas, right eye 800 * 640 color image datas by componentwise by the stereo-picture control circuit.
The bootable person's of wearing of above-mentioned stereoscopic image data attention, make its optic centre do distance, about, up and down, aggregate motion such as circumference, reach exercise, vision correction and the function of health care of eye muscle.
Except the above-mentioned function that human eye is performed physical exercise, wear-type vision of the present utility model strengthens system and also can be used for: the physics and the psychotherapy of (1) myopia, amblyopia and other ophthalmic; (2) individual common three-dimensional film is play; (3) head mounted display of medical Minimally Invasive Surgery; (4) head mounted display of virtual reality.
