Abstract

PURPOSE:To enable a stereoscopic vision of a two dimensional animation image by providing a light beam opening and closing device on right and left eye light receiving sections, and alternatively opening and closing this device and alternatively observing the images or TV image which are fed by one frame. CONSTITUTION:Liquid crystals are used for a right eye device 1 and a left eye device 2 to which a driving power is applied or not applied by a light beam opening and closing control section 3 so that the light beam transmission characteristics of the liquid crystal perform the opening and closing operations. When the opening and closing time interval is synchronized with the frame feed of the images, the animation video, which is frame fed, is alternatively received by the right and the left eye receiving sections. In this case, these exists a slight difference among the frame fed animation videos. Since these frames are alternatively introduced into the right and left eyes and the persistence of vision effect of a brain works, a difference in vision required to obtain a three dimensional stereoscopic vision is approximately constructed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to stereoscopic spectacles for producing a three-dimensional stereoscopic dynamic screen image which gives a realistic sensation when worn by a viewer while retaining the normal two-dimensional dynamic screen image of a television or movie. Regarding

[0002]

2. Description of the Related Art A person generally obtains a stereoscopic effect by synthesizing and judging in the brain that the shapes and the viewing angles of the right eye and the left eye, which are located slightly apart from each other on the face, are different. Is considered to be due to Therefore, conventionally, in order to stereoscopically view an image, it has been necessary to sense different right-eye images and left-eye images simultaneously and separately for the right and left eyes. The screen for the right eye and the screen for the left eye are separated from each other by viewing them through eyeglasses each having a different color filter, and projecting each through a polarizing lens and having a corresponding deflection glass. By viewing through glasses, each screen was placed near each eye 2
By receiving images on each of the receivers of the stand and seeing them, or by providing a lenticular lens on the screen and viewing the corresponding images with a limited field of view of the rays that are optically emitted separately to the right and left, etc. was there.

[0003]

The above-mentioned conventional technique is
The original video screen required two types for the right eye and the left eye, and a special device for stereoscopic reproduction was also indispensable. For this reason, it is expensive and complicated, and it is difficult to popularize it except for special applications. According to the present invention, the original image screen may be a normal two-dimensional moving screen such as a television or a movie, and a substantially three-dimensional stereoscopic sensation can be obtained by simply wearing or using glasses having a simple device. A moving image screen having In principle, the original image screen is frame-fed at a constant speed or cycle to form a moving screen, but this and the above-mentioned glasses do not need to be particularly connected and are independent, and the structure and handling are simple.

[0004]

SUMMARY OF THE INVENTION The present invention is mainly directed to a right-eye light receiving portion and a light beam opening / closing device portion, a left eye light receiving portion and a light beam opening / closing device portion, a light beam opening / closing device control portion, and an eyeglass main body including them. It is composed of

[0005]

With this structure, the light beam opening / closing device for the right-eye light receiving unit and the light beam opening / closing device for the left eye light receiving unit are alternately opened and closed by the light beam opening / closing device control unit. Now, the number of times per unit time including "open" and "closed" of one of the light receiving parts for the right eye or the left eye is equal to the number of frame advance per unit time of the target moving image to be viewed, The "closed" state and the "closed" state are maintained for a time period in which approximately one frame of the target image is sent per state. Further, at the same time, one of the light-receiving portions for the right eye and the light-receiving portion for the left eye are in the "closed" state when the other is "open". Here, the "open" state means that the light receiving section is in a light receiving state through the light of the screen,
On the contrary, "closed" means a non-light receiving state. As a result, the target moving screen image is sequentially received by the right-eye light receiving unit, then the left-eye light receiving unit, and by repeating the same every frame. Therefore, the target moving picture image received in this manner is viewed by the right eye, then the left eye, and the repetition thereof for each frame advance. At this time, in principle, there is a slight difference in the moving screen image for each frame advance. That is, generally, the near view causes a larger movement within the screen per frame than the distant view. If this is taken separately for the right eye and the left eye as described above, and if it is performed quickly enough to cause the afterimage effect in the brain, the difference in shape and viewing angle required to obtain the above-mentioned three-dimensional stereoscopic sensation can be approximated. To configure. As a result, in the case of a moving screen in which the near view moves to the left and right relative to the distant view, in particular, even though the original screen is a two-dimensional image, it is substantially 3
It can be seen as a three-dimensional image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention shown in FIG. 1 will be described below. In the figure, (1) is a right-eye light receiving part and a light beam opening / closing device part (hereinafter right eye device part), (2) is a left eye light receiving part and light beam opening / closing device part (hereinafter left eye device part), and (3) is A light beam opening / closing device control unit, and (4) show the spectacle body.

As an example, liquid crystal is used for the right-eye device section (1) and the left-eye apparatus section (2), and a driving power is applied or not applied to the liquid crystal, and the liquid crystal light beam passage is achieved. By setting the performance to be substantially present or absent, the light from the image cannot substantially pass through the respective light receiving portions, that is, the light is received so as to be "open" or "closed". This operation is (3)
The light beam switching device control unit appropriately controls the application and non-application strength and speed of the driving power and the switching between the right eye and the left eye so as to obtain the effect that matches the initial purpose as described above. . In FIG. 1, the state of the eyeglasses at a certain time is (2) indicated by diagonal lines that only the left eye device unit is “closed”, and thus the other (1) right eye device unit is in the “open” state. Indicates that. In addition, such opening and closing operations for light reception can be performed by a mechanical device, for example, by sliding or rotating a plate (light-shielding plate) of a size that blocks light reception by one eye alternately by one frame at a time. It is possible (not shown). Further, the present principle can be used not only as eyeglasses to be worn on the face but also as separately installed eyeglasses in which a person looks a little away from the eyes.

FIG. 1 shows a block diagram of the device of the present invention.

[0009]

As described above, according to the present invention, the ordinary two-dimensional moving picture is not processed at all, and the viewer can wear or use the glasses according to the principle of the present invention. It can be enjoyed as a practical three-dimensional stereoscopic moving image easily and freely. For this reason, it is expected that the game machine, televisions, movies, and the like, which require a sense of presence, will be greatly expanded into fields that have been relatively restricted due to time and cost.
