Abstract

The invention relates to a display mode of stereotome, known as virtual image stereotome. Which differs from the traditional stereotome display mode is that it locates left view and right view overlapped at the same position or locates them adjacent side-to-side in traditional mode, while virtual image stereotome locates the right view and left view of the stertotome adjacent up and down.

Description

Virtual image stereo-picture

The present invention relates to a kind of display mode of stereo-picture.The demonstration of so-called stereo-picture, promptly be the effect of emulation binocular vision, make two of the people to see two images taking from different perspectives respectively, the image that we see left eye abbreviates left figure as, the image that right eye is seen abbreviates right figure as and since about the difference of figure make the people produce stereoscopic vision.

Figure of description is described as follows:

The adjacent stereo-picture observational technique in Fig. 1 left and right sides.Figure 1A, intersection observation, Figure 1B, parallel observations method.

Fig. 2 virtual image stereo-picture display mode.Figure 1A, the display mode when screen or paper longitudinal direction length are big, Figure 1B, the display mode when screen or paper transverse direction length are big.

The observational technique of Fig. 3 virtual image stereo-picture.

The implementation of stereo-picture is a lot, and its relative merits are respectively arranged, such as redness figure and green figure are superimposed, and re-uses red green color filter sheet and watches, and the image making of this mode is simple and easy to do, and its shortcoming is a color distortion.Perhaps use polarized light projection equipment projection stereo-picture, watch by the polarized light color filter film, its shortcoming is that the projection equipment cost is higher.Be quick Alternation Display left and right sides image on display screen in addition, watch that its shortcoming is that screen flicker easily causes eye fatigue, and this kind mode can't be printed on stereotome on the paper by the glasses that liquid crystal shutter is installed.In addition, also have a kind of special three-dimensional display, stereoeffect is better, but its price is very high.The fan of some stereotome, through training, can not wear and scheme the stereo-picture of placed adjacent side by side about anaglyph spectacles is watched, as shown in Figure 1, its method is to change the human visual custom, adopts parallel observations method or intersection observation, and promptly observer's left eye is observed a figure, right eye is observed another figure, thereby produces stereoeffect.This method does not have specific (special) requirements to the demonstration of image, need not to use anaglyph spectacles yet, but this method easily causes visual fatigue.

The objective of the invention is to design a kind of new stereo-picture display mode, aspect cost, make it not rely on expensive polarized light projection equipment or special-purpose three-dimensional display, on regular display or TV, can directly show, perhaps be printed on the common printed thing; Aspect image quality, can make the people see the clear picture of colour, flicker free; Watching on the complexity, need not training, can directly see stereo-picture.

The display mode of inventing based on above purpose is called virtual image stereo-picture, it is characterized in that: as shown in Figure 2, left figure and right figure are placed on diverse location, and neighbouring, and non-traditional overlapping same position or the left and right sides placed adjacent of being placed on.

Specifically, when projection on televisor during three-dimensional video disc,, then can be two zones up and down with screen divider if the horizontal vertical ratio of film is 2.35: 1, the left figure of last zone demonstration, the right figure of lower area demonstration; If the horizontal vertical ratio of program 4: 3,3: 2 or 16: 9 then can vertically be placed screen, screen is divided into two zones up and down, last zone shows left figure, lower area shows right figure.

Watch this stereo-picture need use special anaglyph spectacles, the pattern of anaglyph spectacles is a lot, and we are only for be used for explanation with an example.As shown in Figure 3, be that trapezoidal eyeglass is made anaglyph spectacles with two longitudinal sections, the end that an eyeglass is thin makes progress, and the end that another eyeglass is thin is downward.When left eye sees through the last figure that eyeglass is observed neighbouring placement image, when right eye saw through eyeglass observation figure below, owing to refraction action, two what in fact see was the two figure virtual images that coincide with the centre position, owing to the difference of two images produces stereoscopic vision.

So far, we have illustrated the mode and the principle of virtual image stereo-picture, and the present invention also has an advantage, promptly also can see the picture rich in detail of no ghost image under the situation of not wearing anaglyph spectacles.Because the present invention need not special projecting device, can be applicable to fields such as three-dimensional television, three-dimensional video disc, 3d gaming and three-dimensional books.

Claims

A kind of display mode of stereo-picture.It is characterized in that: when showing stereo-picture, the image that image that left eye should be seen and right eye should be seen is placed on diverse location, and is neighbouring, and non-traditional overlappingly is placed on same position or the left and right sides is adjacent.
