Abstract

The method involves recording optical information of right image and left image tanken of a subject changing an optic angle in e.g. a picture in a frame of a film without a simultaneous overlap of the left and right 3-dimensional optical information, so that they can be alternately arranged. This is followed by revival into a 3-dimensional image. Collimated optical information is passed through a multiple slit grating to resolve it into two components. A group of inventions are claimed including producing a 3-dimensional image on a photograph, a movie and a TV image.

The present invention relates to a three-dimensional image, and to produce a three-dimensional image for the purpose of realizing a screen that represents a three-dimensional image, not as a screen for displaying a planar image in a photograph, movie, OHP, television and video screen, etc. It relates to a method, an apparatus and various devices. Conventionally, in order to realize a stereoscopic image, the projector is projected using two projectors equipped with a polarizing filter for passing only light polarized vertically or horizontally, and then wearing the glasses with the polarizing filter again and viewing the stereoscopic image. Holography using laser light is a method of realizing an image. However, holography is a technique of photographing using the coherence of light having a single color and a single wavelength, and recording and reproducing stereoscopic images of a stationary object is difficult. It is possible, however, to observe a stereoscopic image only in a limited optical path range through which an object wave, an interference light, passes, and it is impossible to photograph a moving object. Also, even if the object is stationary, the picture can be taken only under ideal conditions without vibration. As another conventional stereoscopic image implementation method, as shown in FIG. 1, a stereo camera or a stereo camera equipped with a stereo photo adapter having two light incidences at intervals of about 6 cm to 7 cm is used. There is a method of constructing a stereoscopic image by viewing a stereo picture composed of two screens taken through a stereo view. Conventional techniques include Japanese Patent Laid-Open Nos. 64-72690, 64-47192, 59-95789, 60-85489, 60-102086, 1-281892, 1-205120, US Pat. No. 4017166, and the like. All of them use the optical properties of polarized light, and must see and wear glasses that require polarizing filters to see stereoscopic images.

In addition, Japanese Patent Laid-Open Nos. 昭 64-41392, 昭 64-31273, 平 1-321568, 平 2-39690, etc., are composed of complex mechanical and electro-electronic techniques to reproduce stereoscopic images, and also realize their practicality. Japanese Patent Laid-Open No. Hei 2-162893 is a method of imaging an image to be observed in a loss including imaging fluorescent particles using a laser light source. Korean Patent Laid-Open No. 2-250591 uses a holography method using coherent laser light, which is artificial light, in which case a laser beam, which is a special light source, is used. It is necessary, and it is almost impossible to photograph a wide landscape such as the outdoors and moving objects with the current technology trend, and even for indoor photography, a high-power laser beam is required. Same person If you are shooting it is also to follow the retina (網膜) the risk of hurt (危險 性) lose sight (視力) of the human eye. U.S. Patent-4125849 discloses a photo having stereoscopic optical information on a film behind the lenticular screen by passing optical information of a collimated subject through an optical system through a lenticular screen composed of cylindrical lenses. It is about how to take pictures.

In the case where the lenticular screen is used as described above, it is difficult to obtain a clear and clear three-dimensional image in reality due to the lack of optical information in the image formed on the film. However, in the present invention, by using the properties of the optical basic principle of light, it is possible to record or reproduce clean stereoscopic images simply and efficiently without using a laser light or a polarizing filter.

The present invention is composed of a group of inventions for making stereoscopic images, but the concepts are roughly divided into three forms as follows.

First, the optical information of the upper right (r) and the upper left (1) of photographing the subject at different wide angles are alternately shifted without overlapping left and right stereoscopic optical information in one screen in one frame of the film. A method of recording and reproducing stereoscopic images, which are recorded so that they are recorded in a frame and then reproduced again as a stereoscopic image through the film. Second, the upper right image of a subject photographed by dividing left and right in a frame of film at different wide angles. r) and projecting independent images of the upper left image (l) onto one screen and recreating them into stereoscopic images; and third, four or more even-numbered TV cameras centering on the subject. Two left images (1 ₂ , 1 ₁ ) and two right images (r ₁ , r ₂ ) or images of four subjects taken at a certain distance from left to right Each independent image can be classified into a method of projecting the same image on a single screen and recreating it into a stereoscopic image. In this case, when looking at a film on which stereoscopic optical information is recorded for reproducing a stereoscopic image, in the first case, images of the upper right image (r) and the left image (1) have been recorded simultaneously in one screen. However, in the second case, the right image (r) and the left image (1) are divided into two independent images, and in the third case, there are four or more even-numbered televisions with a certain distance left to right with respect to the subject. Since a camera is installed to capture an image of a subject, independent images of as many television cameras can be obtained by dividing the subject from left to right around the subject. As in the three cases described above, when the projection is performed on the stereoscopic image reproduction screen in order to reproduce the stereoscopic optical information recorded in the stereoscopic image again, all three cases are reproduced as stereoscopic images, The left eye recognizes the information on the left and the viewer can see the stereoscopic image.

In detail, first, in the case of a three-dimensional photograph, light information emitted by a subject is collimated through a camera lens, and the collimated light information is again converted into a lens. Equally spaced multiple slits with the same width of opaque parts and the width of opaque parts installed behind them, with the lattice arrangement perpendicular to the ground The three-dimensional optical information decomposed into two (r, 1) components is decomposed while passing through the grating, and the three-dimensional optical information decomposed into these two components has the same width as that of the transparent part and the width of the opaque part. Stereoscopic optical information on a negative film located at an upper surface spaced at regular intervals behind an equally spaced multiple slits lattice arranged perpendicular to the ground. Deficiency and overlapping These are arranged in turn to form a stereoscopic optical information on the negative film. When the stereoscopic photo information formed on the film is printed, the photo having stereoscopic optical information ( I)

Second, in the case of a stereoscopic movie, the optical information emitted by a subject is collimated through a camera lens, and this is again equal to the multiple of equal intervals in which the width of the transparent part and the width of the opaque part are the same and the lattice arrangement is arranged perpendicular to the ground. When the slits grating is separated into two pieces of stereoscopic optical information, the three-dimensional optical information without missing or overlapping optical information is separated on the positive film placed on the upper surface at regular intervals from the grating. The image of the subject you have is recorded. In this way, the image of the subject having stereoscopic optical information without optical information missing or overlapping is recorded. In this way, when a positive film on which stereoscopic optical information is recorded is projected on a stereoscopic image reproduction screen of the present invention by a projector, a stereoscopic movie appears. At this time, in the case of the first three-dimensional photograph or the second three-dimensional movie, if the negative film or the positive film or the photo with the stereoscopic information is visually seen, it looks like the film or the photo with the conventional planar information, but the stereoscopic optical information is actually It is included. When a positive film having stereoscopic optical information is projected onto a stereoscopic image reproduction screen of the present invention or when a conventional lenticular screen is placed on a photograph having stereoscopic optical information, a stereoscopic image is found.

According to another embodiment of the present invention, the stereoscopic movie of the present invention separates and projects optical information on a positive film in which a right image (r) and a left image (1) divided into left and right are independently projected in a frame of the film so as to conform to a stereoscopic image reproduction screen. There is a projection that reproduces a three-dimensional movie. Third, in the case of realizing stereoscopic projection through a stereoscopic television receiver, the width of the transparent portion and the width of the opaque portion of the face plate are taken from the image pickup surface of the conventional tele distribution camera or video carrera consisting of a face plate, a transparent conductive film, and an optical conductive film. This same, lattice arrangement is replaced by an equally spaced multiple slits lattice arranged perpendicular to the ground, or between the transparent plate and the face plate of the imaging plane in a conventional imaging tube. The width of the opaque parts is the same and the lattice arrangement is replaced by an equally spaced multiple slits lattice arranged perpendicular to the ground or transparent between the face plate and the transparent conductive film of the imaging plane on a conventional imaging plane. The width of the part and the width of the opaque part are the same, and the lattice arrangement is perpendicular to the ground. When a multi-level grid is installed, the light information emitted by the subject is converted into an electric strength signal capable of representing a stereoscopic image, and the three-dimensional image signal of the electric strength is converted into a stereoscopic image on a stereoscopic television receiver again. It can be converted into a stereoscopic television image.

Another type of stereoscopic television receiver is to separately separate today's image (r) and left image (l), and project and match the two separate images on a stereoscopic image reproduction screen to reproduce stereoscopic images. The equally spaced multiple slits lattice in which the width of the transparent part and the width of the opaque part are the same and the lattice arrangement is arranged perpendicular to the ground have the same width of the transparent part and the width of the opaque part. The function can also be performed by an equally spaced multiple photographic plate grid arranged vertically with respect to the ground. Another type of stereoscopic television receiver is a two-left image (l ₂ , an image of four subjects photographed by four or more even-numbered television cameras installed at a certain distance from left to right with respect to a subject). l ₁ ) and two independent images (r ₁ , r ₂ ) or more independent images are projected to match the stereoscopic image reproduction screen to reproduce stereoscopic images.

In this case, the structure of the grid formed on the stereoscopic image reproduction screen is the same as that of the transparent portion and the width of the opaque portion. Unlike the equally spaced multiple photo plate grids in which the width of the portion and the width of the opacity are the same and the lattice arrangement is arranged vertically with respect to the ground, the width of the transparent portion is narrower than the width of the opacity at a constant ratio The reason for this is that the image of many subjects of more than four (ℓ ₂ , ℓ ₁ , r ₁ , r ₂ ) photographed from as many directions as possible is narrowed at a constant ratio compared to the width of the opaque portion. This is to image an image decomposed into three-dimensional optical information by passing through a lattice, and to form an image on a screen in the absence of optical information. Only two images divided into upper right (r) and left upper (ℓ) are displayed on this stereoscopic image reproduction screen, which is composed of a lattice whose width is narrower than the width of the opaque part at a constant ratio. Projection results in missing portions of optical information in the image formed through the lattice. The arrangement of the lattice is perpendicular to the ground means that an equally spaced multiple slits grating or an equally spaced multiple photographic plate grating or transparent with the same width of the transparent portion and the width of the opaque portion Negative spacing multiple slits lattice in which the width of the part is narrowly formed at a constant ratio compared to the width of the opaque part are the same. In addition, various apparatuses and methods not yet mentioned in the present invention and stereoscopic cameras, stereoscopic television cameras and stereoscopic video cameras, stereoscopic television receivers, stereoscopic image reproduction screens, and the like, which are used in the present invention to implement stereoscopic images, will be described later. It will be described in detail based on the embodiment.

Thereafter, for convenience, the width of the transparent portion and the width of the opacity portion are the same, and the evenly spaced multiple slits lattice in which the lattice arrangement is arranged perpendicular to the ground are vertical multi slits lattice, and the width and opacity of the transparent portion. An equally spaced multiple photographic plate lattice in which the widths of the parts are the same and the lattice arrangement is arranged perpendicular to the ground will also be referred to as a vertical multiple photographic plate lattice.

Herein, the contents of the present invention will be described in detail with reference to the accompanying drawings.

1 is a stereo photo adapter 2, which is an accessory that enables stereo photography in front of a photographing lens of a photo camera that is generally used. This stereo photograph adapter uses four mirrors (3, 4, 5, 6) to separate the light information incident on the lens from side to side, so that the two images are divided into left and right images as shown in FIG. It is a device to take a stereo picture (Q).

In addition, two photographic lenses are usually placed side by side with a space of about 6cm to 7cm, so that a stereo camera can be made by a stereo camera, a special camera that allows you to take two photos from side to side when you press the shutter. When the stereo photograph thus produced is put into a conventional stereo view 7 as shown in Fig. 3, the screen is three-dimensional. However, it is possible to make a three-dimensional image by the conventional method as described above. However, in this case, not only the two left and right photographs are required, but also the disadvantage that the image of the subject in which three-dimensional optical information is recorded in one frame of the film cannot be taken continuously. Will be.

4 and 5 illustrate a cross-sectional view of an equally spaced grating arranged perpendicularly to the ground, which is important for use in the present invention as a stereoscopic optical information decomposing means. Grid 20 ', which is a structure in which the slits are completely transparent and the slit and the slits are completely opaque and have an equal interval structure having the transparent portions 100 and the opaque portions 200 having the same width. Equally spaced multiple photographic plate grids (20 "') arranged vertically with respect to the ground created in the process of being settled and settled on the photographic plate, when changing from transparent to opaque, the change of transparency occurs continuously and does not occur suddenly. The intensity of light is continuously changed from the minimum value to the maximum value. As a result, the amplitude of light 400 changes like a sine curve. In the first and first diffraction waves, more light is collected than the higher diffraction waves.

However, the amplitude of light 300 in the multiple slit grating 20 'of FIG. 4 changes rapidly from above the slit to have a constant amplitude value.

When the vertical equally spaced multiple slit gratings 20 'or vertical equally spaced multiple photo plate gratings 20 "are positioned at a predetermined distance in front of the top surface of the camera, the subject collimated through the optical system of the camera The optical information of the object can be decomposed into stereoscopic light, so that the stereoscopic optical information of the subject can be clearly recorded on the film located on the upper surface. In general, the physico-optical diffraction of a light beam 11 shows that the distance between the slits 9 is generally close when the light beam 8 passes through a narrow transparent part called the slit 9 of the grating. Although the luminous flux 11 can be observed as much as the width of the slit 9, the luminous flux passing through the slit 9 spreads farther away from the slit 9 so that the bright part 15 of the center part can be observed. And darker areas (15 ', 15 ", 15"') It can be expressed as an amplitude (16), which is the intensity of an optical wavelength, in which the light beam spreads wider as the light beam passing through the slit 9 moves away from the slit 9 to correspond to the amplitude 16. It means a diffraction pattern.

This is called the Fraunhofer diffraction pattern (14) and the physico-optical formula associated with the appearance of this Fraunhofer diffraction pattern (14) is This formula means that the light beam 8 passes through the slit 9 and is then diffracted to show the width (x °) of the light beam. Becomes When this is solved and explained, the width (x) of the light beam passing through the slit 9 is proportional to the distance D between the slit 9 and the screen 13 with the observer, and the width of the slit 9 It is inversely proportional to (d), which means that it is proportional to the wavelength λ of the light beam passing through the slit 9. In the laboratory, a light ray passing through the slit 9 mainly uses a plane wave of monochromatic light to clearly observe the Fraunhofer diffraction pattern 14. The distance from the slit 9 at which the Fraunhofer diffraction 14 starts to appear becomes 2D ² / λ.

The brightest part of the center of the Fraunhofer diffraction pattern 14 generated on the screen 13 by the light beam 8 passing through the slit 9 is called the zero order wave 15 and the amplitude The intensity of 16 is maximum. As it spreads to the periphery, it is divided into waves of 1st order (15 '), 2nd order (15 "), 3rd order (15'"), and the intensity of brightness and amplitude (16) decreases little by little. (15 ") and 3rd order (15 '") diffraction waves are called high order diffraction waves. In addition, as shown in FIG. 6, a Fresnel region in which the light beams passing through the slit 9 hardly spread and a beam 11 corresponding to the width of the slit 9 can be obtained. 12) The above-described high-order diffraction waves do not appear in the Fresnel region, and the speeding in these regions is collimated. Outside this Fresnel region 12, Fraunhofer diffraction patterns 14 with higher order diffraction waves 15 ', 15 ", 15'" begin to appear. 7 shows light information r and L of a subject 17 collimated through an optical system 18 of a camera whose center portion is shielded by a light shielding film 18 'positioned perpendicular to the ground. It is decomposed into three-dimensional optical information through a vertically spaced multiple slit grating 20 'or an equally spaced photographic plate grid 20 " positioned at a predetermined distance 19' in front of the upper surface 19. An image of the subject 17 having stereoscopic optical information r, l in a state in which there is no deficiency and overlap of optical information 20 '"on the film 23 positioned in 19). It is sectional drawing which shows the state in which (L'↔R ') is clearly recorded.

This is because the image (L'↔R ') of the subject 17 having the stereoscopic optical information (l, r) in the state (20' ") without the lack and overlap of the optical information as shown in the object of the present invention Recorded on the film 23 located at

To achieve this, you must use an equally spaced multiple slit grating 20 'that is arranged perpendicular to the ground or an equally spaced multiple photographic dry plate grating 20 "that is arranged perpendicular to the ground. And the distance 19 'from the upper surface 19 on which the film 23 is located must always remain constant in the Fresnel region, since as shown in FIG. Only within the close range within the Fresnel region, it is possible to obtain clear collimated stereoscopic optical information as much as the width d of the slit 9 without high-order diffraction waves, as well as FIGS. 4 and 5. Vertical equally spaced slit gratings 20 'or widths as shown in FIG. 7 must be equally spaced and equally spaced, as shown in FIG. Equal interval Only then, the image (L'↔R ') of the subject 17 having stereoscopic optical information (l, r) without missing or overlapping optical information on the film located on the gating top surface 19 as shown in FIG. Can be recorded.

In addition, the lattice arrangement of the vertically spaced multiple slit gratings 20 'or the vertically spaced multiple photographic gratings 20 "must be arranged perpendicular to the ground, and the center portion of the optical system 18 of the camera The light shielding film 18 ', which is shielded from light, should also be positioned perpendicular to the ground so that it can be adapted and adapted to the human binoculars located about 6.3 cm to 6.5 cm apart. The transverse three-dimensional optical information which can reproduce the parallax effect and the three-dimensional effect can be decomposed, and the width of the light shielding film 18 'which shields the center part of the camera optical system 18 is eliminated. (18 ") should be about 6.3cm ~ 6.5cm to obtain lateral stereoscopic optical information that can be adapted and adapted to the human binoculars located about 6.3cm ~ 6.5cm laterally. 6.3cm to 6.5c in most cases in camera lens diameter Since it cannot be more than m, the stereo photo adapter 29 of the present invention described in FIG. 11 should be mounted in front of the optical system 18 of the camera. In this case, the light shielding film 18 'is unnecessary.

Fresnel in front of the top surface of all ordinary handheld cameras, cinematographers, television cameras and video cameras, either vertically spaced multiple slit grating 20 'or vertically spaced multiple photo plate grid 20'. When positioned at a certain distance within the area, it must be positioned perpendicular to the ground. [0049] FIG. 8 shows that the width 21 " of the opaque portion provided between the optical system 18 and the image surface 19 is the width of the transparent portion ( A cross-sectional view showing the function of the unevenly spaced multiple slit gratings 21 wider than 21 ", resulting in missing portions 21 'of the optical information formed on the film 23 located on the upper surface 19. The reason is that the opaque portion 21 '"blocks the optical information excessively because the width of the opaque portion 21'" of the unequal interval multiple slit grating 21 is wider than the width of the transparent portion 21 ". . In this case, if there is no missing portion 21 'of the optical information in the image (L'↔R') formed on the upper surface 19, the distance between the upper surface 19 and the inequality grating is shown in FIG. It must be installed farther than a certain distance 19 'between the upper surface 19 and the vertically spaced slit grating 20'. In this case, the light beam passing through the slit by diffraction, a unique function of the slit grating, Image on the upper surface 19 due to the appearance of higher-order diffraction waves such as Fraunhofer diffraction diffracted in different directions according to different light wavelengths included in Confusion arises in the color tone of the image which is to be taken, and thus no clear image is formed.

FIG. 9 is a state diagram when an unevenly spaced multiple slit grating 22 having a wider width than the width of the opaque portion 22 '″ is used, and an image L formed on the upper surface 19 is formed. The overlapped portion 22 'is decomposed into three-dimensional optical information due to the overlapped portion 22' of the optical information, and consequently the overlapped portion 22 'of the optical information appears. This results in the same result as a normal two-dimensional plan view. This phenomenon occurs because the width of the opaque portion 22 "'of the unequal interval multiple slit grating 22 is smaller than the width of the transparent portion 22", and it is impossible to reproduce a stereoscopic image using such a film. FIG. 10 shows the structure of a three-dimensional camera, which is an embodiment of the present invention. An optical system 18 and a light shielding film 18 'mounted on a central portion of the lens when the diameter of the camera lens is about 6.3 cm to 6.5 cm or more. ), A stereoscopic optical information decomposing means 20 for realizing a stereoscopic image, and a film 23 on the upper surface 19 having a predetermined distance behind the stereoscopic optical information decomposing means 20.

When the photograph is taken by the stereoscopic camera configured as described above, the optical information r and l of the subject 17 collimated through the optical system 18 as described above with reference to FIG. 7 is the stereoscopic optical information decomposing means 20. Films located on the upper surface 19 after being decomposed into two-dimensional collimated optical information (r, l) of two slit widths collimated by the slit width through an equally spaced multiple slit grating 20 'arranged perpendicular to the ground ( Since the image is formed in Fig. 23), it is possible to obtain a film in which stereoscopic optical information is recorded with only one screen. At this time, by shooting continuously with a positive film and projecting on the stereoscopic image reproduction screens 61, 62, 68 of the present invention shown in FIG. 22 or 23 or 24 using an existing projector. We can see a phenomenal phenomenon, which is caused by the vertically spaced multiple slit gratings 20 'as shown in FIGS. The function of the vertically spaced multiple slit gratings 20 'will be described with reference to Fig. 10. Fig. 10 shows the light information emitted by the subject 17 (r, ℓ). ) Is passed through the optical system 18 and then collimated and then through the vertically spaced, multiple-slit grating 20 ', which is a kind of the stereoscopic optical information decomposing means 20, right and left. The number of stereoscopic optical information (r, ℓ) decomposed into two types The film 23 is located on the upper surface 19 spaced apart by a certain distance 19 'behind the equally spaced multiple slit gratings 20', which clearly shows the state of being alternately recorded without deficiencies and overlapping of optical information. The fact that stereoscopic optical information of two components, right (r) and left (ℓ), which can reproduce parallax effect and stereoscopic effect, is alternately arranged without overlapping and without missing parts has an important meaning.

That is, when stereoscopic optical information (r, l) without defects and overlapping are arranged alternately, the positive film having this state is reproduced in the stereoscopic image of the present invention shown in FIGS. 22, 23 and 24. Projection to the screens 61, 62, 68, etc., produces a stereoscopic image without missing optical information. However, as shown in FIGS. If there is a portion 22 ', the image overlaps in the overlapping portion 22', and a clean stereoscopic image is not obtained due to the missing portion 21 'of the optical information. In particular, when the image is enlarged to a large screen such as a movie, a poor stereoscopic image is reproduced. In the case of the vertically spaced multiple slits grating 20 'and the vertically spaced multiple photo grating 20', the two-dimensional stereoscopic optical information r and ℓ are alternately arranged without overlapping and without defects. This is because the opaque portions of the vertical equal interval multiple slit gratings 20 'prevent the overlap and the transparent portions and the opaque portions of the same width prevent the deficiency of optical information.

The two humans can distinguish the three-dimensional object because the two eyes are located about 6.3cm ~ 6.5cm apart in the lateral direction, so the parallax effect can be felt in the lateral direction. In the case of a stereoscopic camera of the present invention for realizing a stereoscopic image, if the diameter of the lens is 7 cm or more, an optical system provided with a light shielding film having a width of about 6 cm at the center of the lens or the stereo photo adapter of the present invention shown in FIG. When the stereoscopic image produced by the stereoscopic camera 29 'of the present invention with the 29) is reflected on the eyes again, we can see the stereoscopic image that is adapted to the human eye structure.

Therefore, a stereoscopic camera is inserted by inserting a vertical equally spaced multiple slit grating 20 'or a vertical equally spaced multiple photo plate grating 20 " at a predetermined distance in front of an upper surface of a conventional camera having a diameter of a lens such as a movie camera of 7 cm or more. In the case of remodeling, it is possible to obtain stereoscopic optical information that can smoothly implement stereoscopic images, but in general cameras, since the diameter of the lens is usually 7 cm or less, in order to obtain stereoscopic images that conform to the functions of the human eye, FIG. An improved stereo photographic adapter 29 as shown in Fig. 2 should be used, which makes the two mirrors 24, 25 facing the subject 28 approximately 6 cm to 6.5 cm apart from each other. Make the mirrors 26, 27 at a constant angle α, but the rays reflected from the two mirrors 24, 25 facing the angle 28 are two mirrors 26, 2 inside the die. The optical information of the subject 28, which is reflected back at 7 and reflected by the two mirrors 26 and 27, is collimated by the lens optical system 18 to reach the upper surface, so that the two optical paths are defined to coincide on the upper surface. Angle.

The stereo photograph adapter 29 according to the present invention is installed in a general camera having a diameter of 7 cm or less, and the vertical equal interval which is a kind of the stereoscopic optical information decomposing means 20 in front of a predetermined distance of the upper surface of the camera. When the multiple slits grating 20 'is installed, it becomes a stereoscopic camera. In a general camera equipped with such an improved stereo photography adapter 29, when the grating is installed in front of a certain distance on the upper surface, the light information emitted by the subject is collimated by the lens through the stereo photography adapter 29, and again, An image having stereoscopic optical information on the film 23 positioned on the upper surface by being stereoscopic optical information decomposed into two components through a vertical equally spaced multiple slit grating 20 ', which is a kind of decomposition means 20. (像) is recorded, and in this case, the person who has stereoscopic light information becomes a person's eye adaptation.

In addition, the vertically spaced multiple slits grating 20 ', which is a kind of stereoscopic optical information decomposition means 20, located in front of the upper surface of the stereoscopic camera capable of recording an image having stereoscopic optical information. Without moving the above on the optical path and mounting the above-described improved stereo photographic adapter 29 of the present invention, the function of the conventional camera capable of recording a conventional planar image is maintained as it is. Referring now to FIG. 12, a stereoscopic image 32 by a camera of the present invention capable of recording stereoscopic optical information emitted by a subject and two photographs 30 by a conventional stereo camera for obtaining stereoscopic effects Comparing 31), it can be seen that conventionally, two screens 30 and 31 are required to express a stereoscopic image, whereas a stereoscopic photo according to the present invention is possible with only one screen 32.

FIG. 12 is an enlarged view of both of them in order to show the characteristics thereof. Especially, the photograph 32 decomposed into stereoscopic optical information is recorded so that the interval at which stereoscopic optical information of two images is recorded is actually only a few tens of micrometers. It is not unreasonable to be represented on the screen. Since two types of stereoscopic optical information are recorded on one screen 32 without being alternately superimposed, they are continuously photographed with the positive film 33 according to the present invention as shown in FIG. If the projection is performed on the stereoscopic image reproduction screens 61, 62, 68 of the present invention shown in Fig. 24 or Fig. 24, it is possible to conveniently realize the stereoscopic image by using the conventional projector 34 as it is. Based on FIG. 14, the structure of a stereoscopic television camera or a stereoscopic video camera, which is one of the present inventions, will be described.

It is surprising that in the structure of a conventional television camera or a video camera, if only a part of the imaging tube is changed, it becomes a stereoscopic camera capable of recording stereoscopic optical information. The imaging surface of a conventional imaging tube is composed of a face plate 36, a transparent conductive film 37, and an optical conductive film 38, but in the stereoscopic television camera or stereoscopic video camera of the present invention, The imaging surface 35 is composed of a vertically spaced multiple slits grating 20 ', a kind of three-dimensional optical information decomposing means 20, a transparent conductive film 37, and an optical conductive film 38, and is an imaging surface of a conventional imaging tube. It is equivalent to replacing face plate 36 with vertical equally spaced multiple slit gratings 20 'in the structure. In this case, when the vertically spaced multiple slits grating 20 'are thin, the face plate 36 may be positioned in front of the vertically spaced multiple slits grating 20'.

There is, of course, no significant change in function using the vertically spaced multiple photographic plate gratings 20 "instead of the vertically spaced multiple slits grating 20 '. FIG. 11 before the lens optics of a television camera in which the imaging surface is thus configured If the stereo photograph adapter 29 of the present invention described above or the lens is large, photographing a subject without mounting it causes light condensation from an image such as a landscaped person having stereoscopic light information formed on the imaging surface 35. In order to reproduce an electrical signal having stereoscopic image information back to a stereoscopic image, a stereoscopic television receiver is required, and a stereoscopic television receiver, which is an embodiment of the present invention, is now described. But these too change a conventional TV receiver The fact that it can be converted to the stereoscopic television receiver of the present invention has a significant meaning in reality.

In FIG. 15, the structure of the stereoscopic television receiver of the trinescopy type is shown, which is red (R) 43, green (G) 41, and blue (B) through dichroic mirrors 39 and 40. FIG. (42) In a well-known Trineskov television receiver that optically synthesizes color signals from three CRT tubes, optically synthesized stereoscopic information is again enlarged through the optical system 44, and enlarged. The image is configured to be viewed in three dimensions through the stereoscopic image reproduction screens 61, 62, and 68 of the present invention shown in FIGS. 22, 23, and 24, and the effect thereof is the stereoscopic television camera of the present invention or An electrical signal transmitted through a stereoscopic video camera and having stereoscopic image information is converted into a stereoscopic image for viewing. FIG. 16 shows the structure of a stereoscopic rear reflection type telerevision receiver, which receives three electrical signals having stereoscopic image information transmitted from a stereoscopic television camera or stereoscopic video camera of the present invention. ), And the red, green, and blue three-dimensional image information enlarged through the optical system is reflected from the mirror 48, and the image on the front of the mirror 48 is reflected. The enlarged stereoscopic image is matched and imaged on the stereoscopic image reproducing screens 61, 62, and 68 of the present invention shown in FIGS. 22, 23, and 24. FIG. When viewed through the stereoscopic image screens 61, 62, and 68 of the present invention shown in FIGS. 23 and 24, stereoscopic images can be viewed.

In addition, the stereoscopic liquid crystal television receiver which is one of the present inventions is formed by installing a lenticular screen on the front of a known liquid crystal television receiver. The stereoscopic liquid crystal television receiver configured as described above can decompose light information emitted by a subject into stereoscopic optical information of left and right components. Through the image pickup tube having a means capable of reproducing, it is possible to reproduce what has been transmitted as an electrical signal having a stereoscopic image signal back to a stereoscopic image. A stereoscopic television receiver, which is one of the present inventions capable of reproducing stereoscopic images using a color television receiver, which is currently widely used, will be described with reference to FIGS. 17 and 18. Referring to FIGS. 17 and 18, the stereoscopic television set of the present invention is replaced with a lenticular screen 50 formed with the same curvature as the panel glass 49 formed with the conventional constant curvature. In the present invention, the ancestors of the three color cells of red, green, and blue are formed in the vertical direction to form one pixel 51. In the present invention, the ancestors of the three color cells are constituted in the horizontal direction so that one pixel ( 52). The stereoscopic television receiver configured as described above can receive a signal from the stereoscopic television camera or stereoscopic video camera of the present invention and reproduce the continuous stereoscopic image again. As described above, the stereoscopic image reproduction screen for reproducing the stereoscopic image will be described with reference to the drawings. 19 illustrates a known lenticular screen, in which a plurality of fine cylindrical cylinders L having only a constant curvature in a transverse direction made of a medium having a refractive index n 'are arranged vertically and such a cylindrical lens L Are arranged vertically, such a cylindrical lens (L) is arranged vertically, such a cylindrical lens (L) is arranged vertically, and the thickness as much as the focal length (f ') of the physical lens (L). It consists of a hyperplane (P) having. In addition, the hyperplane P of such a known lenticular screen is not opaque but transparent.

In order to understand the optical function of such a cylindrical lens (L), the geometrical optical characteristics of the single-hole lens shown in FIG. 20 will be described as follows. One light spot located on the focal point F in the first medium M ₁ having the refractive index n present on the left side of the single spherical lens L composed of the second medium M ₂ having the refractive index n '. When the light beam 1 ₁ diverges toward the single spherical lens L in the light beam, the light beam parallel to the main axis Zx in the second medium M ₂ after refracting in the single spherical lens L 1 ₂ As a result, the image of the cold spot in the first medium M ₁ is formed at infinity (∞). FIG. 21 shows that in a first medium M ₁ having a refractive index n, a light ray 13 parallel to the main axis A _X enters a single spherical lens L composed of a second medium M ₂ having a refractive index n '. The lower surface is refracted by the single spherical lens L, and the refracted light l ₄ is collected at the focal point F ′ in the second medium M ₂ . In FIG. 21, if there is a light spot on the focal point F ′ in the second medium M ₂ , and if the principle of light reverse is applied thereto, the light beam is composed of the second medium M ₂ . Refraction in the single-spherical lens L results in a light beam parallel to the main axis A _X in the first medium M ₁ having the refractive index n and thus on the focal point F ′ in the second medium M ₂ . As long as there is a light spot, the image is formed at infinity (∞).

In this case, the important fact is that the second focal length f 'toward the second medium M ₂ of the single spherical lens L, which is composed of the second medium M ₂ having the n' and the curvature radius r, is maintained. And the first focal length f on the side of the first medium M ₁ having a refractive index n is not equal. The stereoscopic image reproducing screen 61 used in the present invention does not use the optical information transmission medium as the second medium M ₂ having a refractive index of n ', but the air toward the first medium M ₁ having a refractive index of n is 1. ), The transverse plane (P) is semi-transparent, and the cylindrical lens is always positioned so that it is perpendicular to the ground. Referring to FIG. 22, the configuration of the stereoscopic image reproduction screen 61 of the first aspect of the present invention will be described.

On the opposite side of the observer H, there is an antireflective coating layer 56, and on the inner side there is a first screen 55 having a translucent portion 54 and a translucent portion of the first screen 55 ( The second screen 60, which is a lenticular screen composed of a plurality of fine cylindrical lenses 59 having only a constant curvature in the transverse direction facing the 54, and an air layer having a refractive index n = 1 between them. 57). And the flat surface of the second screen 60 is directed towards the viewer H.

In this case, the distance of the air layer 57 is a distance between the apex 58 of the cylindrical lens 59 constituting the second screen 60 and the translucent portion 54 of the first screen 55. This object distance S is referred to as the distance s and is equal to the focal length of the cylindrical lens 59 constituting the second screen 60. Therefore, the subject of the cylindrical lens 59 in which the stereoscopic image optical information formed on the translucent portion 54 of the first screen 55 constitutes the second screen 60. ) Will act as. Therefore, the three-dimensional image formed on the translucent portion 54 of the first screen 55 forms an image at an infinite circle (∞), thereby forming parallel light beams having respective optical paths. When we observe the parallel light beams having each of these optical paths, we can feel the parallax effect and the three-dimensional effect in the lateral direction.

The first aspect of the stereoscopic image reproducing screen 61 of the present invention is characterized in that the optical information transfer medium between the translucent portion 54 of the first screen 55 and the second screen 60 is an air layer 57. Since the distance between the first screen 55 and the second screen 60 is the focal length of the cylindrical lens 59 constituting the second screen 60, the first distance 55 The thickness and the object distance s of the screen 55 and the second screen 60 can be freely adjusted. To explain this feature, we can apply Gauss's formula for single-life lenses. With reference to Fig. 22, Gauss's formula is applied. Becomes In this case, n denotes the refractive index of the air layer 57, n 'denotes the refractive index of the medium constituting the first screen 55 or the second screen 60, and r denotes the cylindrical constituting the second screen 60. It is the radius of curvature of the lenses 59. s and s' are the object distance and the object distance, respectively, and the object distance s is configured equal to the focal length of the second screen 59. If there is an image that has passed stereoscopic image information on the semi-transparent portion 54 of the first screen 55, as described in FIGS. 20 and 21, light rays emitted from such an image are transmitted to the second screen. After refracting through the cylindrical lenses 59 constituting 60, each optical path becomes a parallel beam so that the image on the translucent portion 54 of the first screen 55 is infinite. The image distance (s'), which is the distance from the cylindrical lenses 59 constituting the second screen 60 to the image formed on the infinity circle (∞) by forming an image at (∞), is infinite. )

Therefore, substituting this relationship into Gauss' formula Will also Becomes Becomes

Since the object distance s is equal to the focal length of the cylindrical lenses 59 constituting the second screen 60. silver Since the space of the object distance (s) in the present invention is air, the refractive index n of the air becomes 1, This is true.

In order to realize a stereoscopic image using a known lenticular screen, the thickness of the screen must be the same as the focal length of the cylindrical lens constituting the lenticular screen, but the first screen 55 forms a screen in the stereoscopic image reproducing screen of the present invention. Regardless of the thickness of the medium and the thickness of the medium forming the second screen 60, not only can the object distance s be reduced as desired, but the first screen 55 and the second screen can be reduced even when the object distance s is reduced. Since the thickness of (60) can be thickened, there is an advantage that a screen can be configured without warping even when the screen is made large.

In addition, an antireflective coating may be applied to the outer surface 56 of the first screen 55 in order to increase light transmittance. However, in the case of known lenticular screens such as the 19th degree, the thickness of the screen is large in order to make a large screen without warping because it is usually made to have a thickness corresponding to the focal length f 'of the cylindrical lens L. It should be thick and the focal length f 'should be long.

The thicker the lenticular screen is, the wider the range for accommodating the ambient light information other than the paraxial luminous characteristics received by each cylindrical lens L constituting the screen is obtained. It becomes difficult to reproduce. In addition, if the focal length f 'of the cylindrical lens L constituting the known lenticular screen is shortened to make a lenticular screen as thin as that, the screen may be warped. . 23 is a cross-sectional view of another stereoscopic image reproducing screen 62 of the present invention, wherein the first screen 64 and the viewer having a constant thickness having an anti-reflective coating film 63 on the surface opposite to the viewer H. Translucent so that images with stereoscopic optical information can be imaged on a hyperplane at the focal length f 'of the cylindrical lens 67 facing H). A stereoscopic image reproduction screen to which a second screen 66, which is a lenticular screen on which a portion 65 is formed, is attached. FIG. 24 is also a cross-sectional view of the third type stereoscopic image reproduction screen 68 according to the present invention. In the lenticular screen 68 having the same thickness as the focal point f ', the translucent portion 69 is formed on the hyperplane to form an image having stereoscopic optical information. One lenticular screen as possible. 25, 26, and 27 show stereoscopic image optical information as shown in FIGS. 13, 15, and 16 on three types of stereoscopic image reproduction screens 61, 62, and 68 of the present invention. In this case, cross-sectional views illustrating stereoscopic image reproducing functions of the stereoscopic image reproducing screens 61, 62, and 68 of the present invention are shown.

The functions of the stereoscopic image reproduction screens 61, 62, and 68 according to the present invention will be described below. On the translucent portions 54, 65, and 69 of the stereoscopic image reproducing screens 61, 62, and 68 of the present invention, the light information is decomposed into right (r) and left (l) and alternately without missing or overlapping optical information. The optical information of the arranged stereoscopic image is taken through the independent optical paths of the right (Er) and the left (E ₁ ) through the cylindrical lens constituting the lenticular screen, respectively, and reaches the observer H's eyes. The same image with different wide angles is formed on the retinas of the right and left eyes of the eye. ) Will be recognized. Hereinafter, a description will be given of an embodiment in which two images of independent left and right images in a film taken from different directions at different left and right sides of a subject are imaged on a single screen and reproduced as multi-dimensional stereoscopic images. would.

FIG. 28 is an exploded view of the reproduction screen 81 of the fourth form, in which an antireflective coating layer 74 is provided on the surface opposite to the viewer H, and the width of the transparent portion 75 'and the opaque portion 75 "are the same. A constant thickness (78 ') formed with a first screen (77) formed with a spaced multiple slit grating (75) or an evenly spaced photographic plate grating and a translucent portion (76) where an image on the viewer (H) side can be imaged. And a third screen (79) with a cylindrical lens (79 ') towards the viewer (H), which constitutes a third screen (79) thick of the third screen (79). The thickness of the cylindrical lenses 79 'is as large as the focal length f'. When these three types of screens 77, 78, and 79 are brought into close contact with each other, they are formed as shown in FIG. A four-dimensional stereoscopic image reproduction screen 81 is obtained.

30 is a partially enlarged view of FIG. 29. FIG. 31 is an explanatory diagram showing an enlarged three-dimensional image reproducing function of the fourth aspect stereoscopic image reproducing screen 81 of the present invention shown in FIG. 29. Use the two television cameras spaced a certain distance from the left to the right of the subject, or attach the conventional stereo photo adapter 2 shown in Fig. 1 to one television camera to capture the electrical signals of the right and outer images. Two independent video information received from a television receiver and two independent video information can be separated to reproduce two independent video images. The two independent video images are reproduced by Bran canals L and R in the television set. Four images of the present invention when the two enlarged and collimated images are inclined to conform to the fourth aspect stereoscopic image reproducing screen 81 of the present invention after passing through the respective optical systems Equally spaced multiple slit gratings 75 or equally spaced multiple photographic plate gratings arranged perpendicular to the ground formed on the first screen 77 of the reproduction screen 81 Through each of the two image information is decomposed into three-dimensional optical information (r, l) to form an image on the translucent portion 76 of the second screen 78 without overlapping and missing, such stereoscopic optical information formed on the second screen Through the lenticular screen where (r, l) is the third screen 79, it takes an independent light path in the left direction E ₁ and the right direction E _r to reach the eye of the observer H and to the left of the observer H. By forming the same image with different wide angles on the retina of the right eye and the right eye, the lateral parallax effect and the integrated three-dimensional effect are recognized in the optic nerve center of the observer (H). In addition, after installing a polarizing filter at an appropriate position of each optical system through which two independent images (r, l) pass, the observer (H) can also observe stereoscopic images by wearing polarized glasses.

This means that three-dimensional images can be viewed even with naked eyes, and that three-dimensional images can be viewed even if a polarizing filter and polarizing glasses using optical properties of polarized light are applied. 32 is an exploded view of yet another fifth aspect stereoscopic reproduction screen of the present invention. Referring to the technical configuration, the first screen 77 and the second screen 78 are formed of the first screen 77 and the second screen described with reference to FIG. Although it is the same as the structure of the 2 screen 78, what comprised the air layer 85 between the 2nd screen 78 and the 3rd screen 82 as the transmission medium of stereoscopic image information is different.

At this time, the air layer distance f between the apex 82 'of the cylindrical lens constituting the third screen 82 which is the lenticular screen and the translucent portion 76 of the second screen 78 is the third screen. It becomes equal to the focal length of the cylindrical lens constituting (82). The cylindrical lens constituting the third screen 82, which is a lenticular screen, faces the translucent portion 76 of the second screen 78. Due to the technical configuration having such a feature, the thickness of the medium constituting the third screen 82 can be freely thick, which allows the screen to maintain stable flatness. Since the size and focal length of the cylindrical lens can be made as small as possible, there is an advantage in that it is possible to reproduce delicate stereoscopic images. 33 is a cross-sectional view of a fifth form stereoscopic image reproduction screen 83 formed when the three types of screens 77, 78, and 82 described in FIG. 32 are brought into close contact with each other, and FIG. 34 is a partially enlarged view of FIG.

FIG. 35 is an explanatory diagram showing a stereoscopic image reproduction function of the fifth type stereoscopic image reproducing screen 83, and performs the same function as described in the description of FIG. 31 to integrate the parallax effect in the transverse direction of the optic nerve of the observer H. It is to recognize the three-dimensional feeling.

36 is an exploded view of the six-dimensional stereoscopic image reproduction screen 92, which has an antireflective coating layer 74 on the surface opposite to the viewer H, and has the same width of the transparent portion 75 'and the opaque portion 75 ". A flat surface in contact with the air layer 90 with the first screen 77 on which the equally spaced multiple slit gratings 75 or the equally spaced photographic plate gratings are formed and the air layer 90 having a constant distance 89 therebetween. The second screen 86 is a lenticular screen made of a translucent portion 87.

If the thickness of the first screen 86 is as thick as the focal length f 'of the cylindrical lenses 86' constituting the second screen 86, the cylindrical lens 86 'is also thick. Are facing towards the observer (H).

When the portion of the leg 88 of the second screen 86 having the same thickness as the distance between the first screen 77 and the air layer 90 is brought into close contact, the sixth shape stereoscopic image having the cross-sectional view as shown in FIG. The reproduction screen 92 is obtained.

The translucent portion 87 of the second screen 86 of the first screen 77 and the second screen 86 constituting the sixth type stereoscopic image reproduction screen 92 is located on the first screen 77. An image having stereoscopic image information decomposed through the grid is formed.

38 is a partially enlarged view of FIG. 37.

FIG. 39 is an explanatory diagram showing a stereoscopic image reproduction function of the sixth type stereoscopic image reproduction screen 92, and performs the same function as described with reference to FIG. It is to recognize the three-dimensional effect integrated with the effect. 40 is an exploded view of a seventh type stereoscopic image reproduction screen 97, which is another type of stereoscopic image reproduction screen, and has an antireflective coating layer 94 on the surface opposite to the viewer H, and is transparent to the transparent portion 93 '. The first screen 95 and the observer (1) where the multiple slit grating 93 or the unevenly spaced multiple photographic plate grating having a width ratio of the portion 93 "is 1: 3. Consisting of a second screen 78 having a constant thickness 78 'having a translucent portion 76 on which an image can be formed on the H), and a cylindrical lens 79' facing toward the viewer H. The third screen 79 is a lenticular screen, and the thickness of the third screen 79 is as much as the focal length f 'of the cylindrical lenses 79' constituting the third screen 79. When these three types of screens 95, 78, and 79 are brought into close contact with each other, the seventh type stereogram having a cross-sectional view as shown in FIG. An image reproduction screen 97. Fig. 42 is a partially enlarged view of Fig. 41. The first screen 77 and the fifth form of the screens constituting the above-described fourth aspect stereoscopic image reproduction screen 81. Figs. The transparent portion 75 'and the opaque portion formed on the first screen 77 and the first screen of the screens constituting the stereoscopic image reproduction screen 83 and the sixth form stereoscopic image reproduction screen 92 ( Unlike the equally spaced multi-slit grating 75 or the equally spaced photographic plate grating having the same width of 75 "), the grating formed on the first screen 95 of the screens constituting the seventh type stereoscopic image reproduction screen 97 Unequal multiple slit grating 93 or uneven spacing with a ratio of 1: 3 between the transparent portion 93 'and the opaque portion 93 ". The reason why the multiple photographic lattice was formed is as follows.

A light source having projections projected onto the fourth type stereoscopic image reproduction screen 81 or the fifth type stereoscopic image reproduction screen 83 or the sixth type stereoscopic image reproduction screen 92 is left. (1) and (1), each of which has a first and a right type of image information from each of the left and right light sources that constitute the fourth, fifth and sixth type stereoscopic image reproduction screens.
