Description
Technical field
The present invention relates to display packing and device, particularly a kind of method for displaying image and device that meets vision physiological.
Background technology
Along with social development, the electronic equipments such as computing machine become an indispensable part in people's work and life.But, long-term in-plant with eye, easily make eyes produce visual fatigue, thereby cause the eye diseases such as visual impairment.
In addition, follow the extension at full speed of internet, three-dimensional digital technology based on computing machine and internet, make people no matter on virtual network or in real life, from greatly to aircraft, steamer, automobile, power station, mansion, building, bridge, little each slight industrial products in life, can see digitized 3D model, animation and the emulation of computer photograph everywhere; And due to the development of 3D technology, the 3D TV let us arising is in recent years in and just can be experienced the fresh of 3D film with dynamic.
Above-mentioned allly all need close eye and/or eye for high strength, easily cause that eyes produce visual impairment, eyeball is dry and astringent, swelling is congested, photophobia is shed tears, dizzy, the livid ring around eye of having a headache, the asthenopic phenomenons such as dim eyesight of even having a sleepless night.
We know, the FOV (Field of View) of human eye be from infinitely as far as limited near, near point is generally at 10-30 centimetre.When eyes are seen when near, the optical axis of two eyes will rotate to an angle, converge on target object, the angle of two optical axis is called set, set=1/L, and unit is " rice angle ", L is the distance of object and eyes, simultaneously for imaging accurately drops on retina, lens surface curvature becomes large (thickening change garden) Here it is the adjusting of eye, and adjusting=1/L unit is " diopter ".People is by the set of two and distance and the position of the different judgment objects of adjusting.When eyes see that time far away, two optical axis are tending towards parallel, L=infinity, set=0, crystalline lens loosens, and regulates=0.
After people's birth, progressively set up basic visual performance by watching and touching, that is: eyes close picture.It similarly is the permeate process (as shown in Figure 1) of an image of image that human eye is seen respectively by right and left eyes that eyes close.
In conjunction with Fig. 2, shown in figure 3, Fig. 3 is taking according to Fig. 2 method the left and right apple picture P obtaining
land P
rbe arranged on optional position identical on the optical axis of two eyes as sighting target, by dividing plate 3-1, two an eye line are kept apart, brain all can form and melt picture, the position of melting the sighting target imaging after picture is on the point of crossing of two optical axis, be consistent with the actual apple imaging of watching optical axis point of crossing, the eyes of Here it is human eye close picture function.
Sighting target P is set beyond the point of crossing of binocular visual axis
land P
rstill can form brain and melt picture, melt picture after target still on optical axis point of crossing.This sighting target setting makes the position of closing picture between sighting target and eyes, namely close image position than sighting target from eyes more close to, therefore, cause two optical axis angles to increase, that is: set increases, and corresponding adjusting is less than set, so visual sense feeling uncomfortable (as shown in Figure 4).What present stereotelevision display packing adopted is arranged on sighting target (display screen) 5-1 position beyond two optical axis point of crossing exactly, imaging 5-2 is presented between eyes and sighting target, so beholder's visual sense feeling is very uncomfortable, what 3D display technique adopted is exactly this mode (as shown in Figure 5).
Along with popularizing of computing machine, people in the face of time of display also more and more longer, but, generally graphoscope is all placed on the front 0.4 meter of left and right of human eye, and it is zero that the picture that display shows differs, and a difference is also zero, now, adjusting=set=2.5 of human eye 6-1, work long hours and can cause visual fatigue, visual impairment (as shown in Figure 6).
Stereotelevision production is synchronously to take with two video cameras, the camera lens spacing of two video cameras is in 70 millimeter, the method that post-production will show according to reduction is carried out necessary parallax adjustment to left and right picture, present signal transmission is the transmission of left-right frames crossing sequence mode, two picture Alternation Display about when demonstration, reappear stereoscopic picture plane by synchronous light valve spectacles.In order to build visual effect on the spot in person, current stereotelevision is taked the overlapping demonstration of left and right picture position, and all close shot pixels all can imaging between screen and eyes.Therefore, make human eye easily produce visual fatigue, the phenomenon such as have a dizzy spell.
Can understand by above-mentioned, in the time that the display frame on display screen causes set to be greater than adjusting, the visual sense feeling of eyes is very uncomfortable, and fatiguability easily causes that dizzy vomiting waits bad reaction; The sensation that set is less than eyes while adjusting is not clearly, and bad reaction is very light, and set equals to regulate while being greater than 1D, and eyes do not have bad reaction substantially.
