Abstract

FIELD: optics, generation of volumetric image when reviewing black-and-white and color images reconstructed by typical movie and TV installations. SUBSTANCE: image reconstructed in screen is reviewed with the aid of glasses through which one eye of viewer perceives total luminous flux of screen and the other eye is shut by opaque plate with hole having diameter 1.0 mm located opposite to pupil. EFFECT: improved clearness of images. 7 cl, 4 dwg

Description

 The invention relates to the reproduction of visual information in three-dimensional form, in particular, to the field of television, cinema, computer technology.

 Known methods for obtaining three-dimensional images by transmitting video signals corresponding to two images of the object and separate viewing by the left and right eyes of images of the reproduced stereo pair on the screen of the receiver of the stereo television device / 1 /.

 There is a method of obtaining a volumetric color image, which consists in a small (0.7 μs) delay in the color "red" signal, as a result of which the contours of the red leaving color image are shifted relative to the contours of the combined blue and green components on the color TV screen. Viewing such an image is carried out through glasses with appropriate color filters for each eye / 2 /.

 The disadvantage of this system is the inability to obtain a black and white surround image in this way.

 A device for obtaining a clear three-dimensional image containing a spectacle frame with a plate placed opposite only one eye, made of a material partially transmitting the light flux, while the second eye of the consumer perceives the full light flux / 3 /.

 Glasses are known having instead of glasses a diaphragm, the diameter and position of which can be adjusted. These glasses increase the clarity and relief of images when watching them, for example on a television screen / 4 /.

 However, in none of the indicated technical solutions does the possibility of simultaneous exposure of the retina of one of the human eyes to the natural one, and to the part of the retina of the other eye by the light flux changed in intensity, be realized.

 The technical result of the invention is the provision of the possibility of obtaining a black-and-white and color three-dimensional image using simple, affordable means while improving the convenience during their operation.

 To achieve the specified technical result, it is proposed in a method for obtaining a three-dimensional image, including simultaneous exposure to the retina of one of the human eyes with a natural one, and to the retina of the other eye, the intensity of the light flux changed by the intensity of the light flux affects the part of the retina, the area of which is determined by the area of the hole passing this light stream. Moreover, the device for obtaining a three-dimensional image can be performed with one opaque plate with a hole ⌀ 1 mm opposite the pupil of the eye, in addition, the plate can be placed with the ability to move from one eye to another, or the device may additionally contain a second plate made identically the first and placed opposite the other eye, while both plates are mounted on the frame with the possibility of alternately lifting, or a lightproof plate with a hole can be stationary It is fixed in a frame either opposite the left or opposite the right eye. Also, the device for obtaining a three-dimensional image can be made in the form of a contact lens made of opaque material with a round hole in the center.

 In figures 1 to 3 depict options for glasses that can be used to obtain a three-dimensional image on the screen.

 The figure 1 shows glasses consisting of a frame with arches 1 and a lightproof plate 2 with a hole with a diameter of 1 mm opposite the pupil. The groove 3 in the mandrel allows you to move the plate 2 along it, which makes it possible to install the plate either opposite the right eye or opposite the left.

 The figure 2 shows glasses for the right eye and for the left.

 The figure 3 shows glasses in which the plates are mounted on hinges 4 so that each plate can be lifted.

 The figure 4 shows a opaque flexible contact lens having a hole 5 with a diameter of 0.5 mm, located opposite the pupil, which is installed directly on the iris of the eye.

 The hole diameter of 1 mm in a lightproof plate inserted into the glasses and the hole diameter of 0.5 mm in the contact lens were selected empirically, which is consistent with the data / 3 /. Looking at a color or black-and-white image on a TV screen, display, or on a movie screen through the glasses or contact lens offered, the viewer sees a three-dimensional image of the picture on the screen. g.
