Description

DETAILED DESCRIPTION OF THE INVENTION Another aspect of the invention relates to a stereoscopic television transmission and reception system capable of producing a pair of stereoscopic signals that are separately perceived by the viewer's eyes without the use of image separating glasses.

[Background technology]

The possibility of creating a stereoscopic or three-dimensional image in a television receiver has not been considered as a practical method, since if a double image were to be transmitted by the transmitter and seen by the viewer. If the viewer is to be received by a receiver, the viewer must of course use the same glass shape conventionally used in connection with the stereoscopic motion surface, and the viewer must use Apart from disconformity, other factors prevent the system from fully accepting, because when glasses are not used, the overlap of the two images that must be manipulated to create a three-dimensional perception is more visible. This is because it becomes impossible for the viewer to see a well-defined image. On the other hand, the mere fact that the transmission and reception of the signal is by scanning the screen by the electron beam itself makes it impossible to practically obtain the transmission of a double image, so that in the prior art the operator could We have made every effort to develop a complete system for transmitting stereoscopic television signals that can be viewed from above.

In view of the above-mentioned obvious difficulties, workers in the television field do not consider that it is possible to convey stereoscopic or three-dimensional images for viewing by viewers with or without glasses. Since then, the field of stereoscopic television has been completely lacking, as no developments or innovations have been made in this field by those working in this technology.

[Purpose and structure of the invention]

The present invention provides a stereoscopic television system that enables stereoscopic or three-dimensional images in a television receiver, the system focusing both convergent and depth optical means to produce two stereoscopic images. 1 rice 2
a stereoscopic television camera having two separate optical means and a servo control; a light-sensitive means coupled to each of the optical means for converting the stereoscopic image into a corresponding video signal; one video camera produced from said light-sensitive means; fast switching means for the alternating passage of signals; television signal transmission means for transmitting alternating video signals passing through said switching means; television signal transmission means for receiving the transmitted television signals and for receiving the transmitted television signals; one television signal receiving means for converting it into a video signal through polarizing coil means, and one exocratic ink screen placed on the image receiving screen of the picture tube, said exocratic ink screen being visible to the viewer's eyes. alternating signals received in opposite angular directions to create the perception of a three-dimensional image by refracting one of the stereoscopic video signals in one of the stereoscopic video signals and the other of the stereoscopic video signal in the other eye of the viewer. The invention comprises a plurality of vertical semi-cylindrical lenses for receiving signals switched on. Best understood from the description.

(Hereinafter in the margin) According to the present invention, a novel system is provided for transmitting and receiving stereo video signals.
Attempts are made to modify both the transmission and reception of TV signals. This is because the observer has the sensation of seeing a three-dimensional image. Similarly, we are trying to make certain modifications to TV cameras, switchers, and receiving devices. All of this is built according to one of several standards shared throughout the world. For example, NTSC.

These include PAL and SECAM. this is,
Providing a breakthrough in the television industry. This is because, for the first time, the device makes it possible to see a three-dimensional image rather than a two-dimensional image as in the case of prior art stems.

It is noted that when using the eyes, ie, using binocular vision, the human brain can sense the signals conveyed by the eyes in three dimensions. The reason is that the positions of the points in the field of view are different, and they are different in the observation of nearby objects in relation to objects that are far away.
induce a certain slight difference. In this way, the human brain receives two different images and merges them to form one three-dimensional image.
).

The average distance between the human eyes is approximately 60 mm, as the eyes are placed in the center of the face and in a vertical plane, which is the distance of the inner canthus of humans. . As mentioned above, the different images received by the pair of hibernations are interpreted by the brain by merging them into a single three-dimensional image, a three-dimensional image. A stereo image, or three-dimensional image, includes height, width, and depth.

The camera used in the Tv/stem according to the invention
, which mimics the human eye and includes two optical assemblies 12 and 13, as shown in FIG. 3 and described below. Instead of one single optical assembly of TV cameras commonly used in prior art systems. This is to obtain a double image, as occurs in the human brain, rather than the reception of a single image in three dimensions. The horizontal separation between the optical assemblies described above should be the same as an anthropomorphic measurement of approximately 60+u.

The complete system according to the invention as shown in FIG. , converting the optical images into video electronic signals, which are sent via appropriate lines 25, 26 to a converting device 2, which comprises a high-frequency switcher 2, which will be described below.

in order to switch the passage of the two above-mentioned video signals arriving via lines 25, 26, thus only one of the above-mentioned signals being allowed to pass at a predetermined time and for conversion. Through the device, this is arranged,
The two video signals are accurately and exactly matched, ie, the left and right signals are mixed, as will be explained later. The video signals to be crossed are connected to the appropriate line 27.
via the transmitter 3, which transmits the above-mentioned signals in a well-known prior art manner. For example, via a suitable antenna, cable pull, carrier or in the form of an electromagnetic wave 28, which
V receiver 4 is received by a corresponding antenna or cable, which in addition to the usual image screen consisting of a picture tube has an additional Xogr
aphtc) screen, which screen includes a plurality of vertically aligned semi-cylindrical aspheric lenses, as described below. The image tube of the TV receiver 4 includes a conventional deflection coil, which may or may not be modified according to the embodiments of the invention described below.

(Hereinafter in the margin) As already mentioned, the embodiment of the invention shown in FIG. have These assemblies are arranged in parallel to focus on very distant objects, ie objects at virtually infinite distance. It is similar to how the human eye is arranged so that the lines of sight are approximately parallel to each other in order to focus on distant objects. This assembly is controlled by suitable servomechanisms (well known and not shown) and a remote device to move the assemblies 12, 13 closer together so that the angle of sight becomes larger when the object is closer. Can focus on objects. This is similar to how the human eye forms a larger visual angle when an object is close to the eye due to the action of the eye muscles.

A television camera according to the invention generally has a housing. A pair of optical elements or lenses 12, 13 are arranged in this housing 1, and on the same axis there are arranged light sensitive elements, such as image analysis tubes 16, 17, 18 shown in FIG. This video analysis tube consists of two assemblies 14 and 15.
and each of the assemblies forms a corresponding optical assembly 12
．． 13 are arranged coaxially with each other. When the transmitted signal is black or white, it may have a single video analysis tube. A camera according to an embodiment of the invention includes an optical assembly 12.1
It also has two conventional eyepieces/lenses so that the camera operator can see the same thing through three. Having thus received different images through each of the eyepieces 10.112), this operator can also determine the manner in which the images are produced by the camera in order to correctly manipulate the operation of the camera. The eyepiece described above may be replaced by a small receiver or monitor provided in the same manner as described for receiver 4 below. Lenover 4 is placed behind camera 12) to provide a stereo video signal to the operator.

Without departing from the spirit and true scope of the invention, the light-sensitive elements 14, 15□ of the camera according to the invention may be selected from a number of different known elements, such as image analysis tubes, charge-coupled devices, etc. should be mentioned. (Left below) Finally, the camera of the present invention has a servo mechanism that controls the remote and angular focusing of the optical assembly 12, 13 and the light sensitive or image analysis assembly 14, 15. This focusing is automatic for remote and stereoscopic images, as is known. This servomechanism may be operated manually or by ultrasonic waves, and is known as described above. The servomechanism is only needed to perform the operations necessary for the camera of the present invention. Said servomechanism thus has the appropriate function of moving the optical assembly 12.13 and the image analysis assembly 14.15 through different solid angles, and at the same time remotely controlling the focusing of each of the optical assemblies 12.13. It is not intended to be limited to a given servomechanism, as long as it is sufficient for.

In order for the TV camera of the present invention to provide special effects, the second
As shown in the figure, this camera has an excessive stereoscopic screen (hyp
er -5tereoscopicity) or an undersized stereoscopic screen (hypo-5tereoscopicity)
Additional equipment may be provided for providing icity). For this purpose, it is necessary to position the optical assembly 12.13 of the camera at a distance greater or less than the distance between the human eyes, indicated by reference numeral 7 in FIG.

For this purpose, in conjunction with the above-mentioned focusing servomechanism,
A further mechanism is provided for moving the two optical assemblies 12, 13 in the direction of arrow 8 to provide an over-stereoscopic view, or in the direction of arrow 9 to provide an under-stereoscopic view.

As is well known, the human eye detects an object f at a distance greater than ′.
When fixed at iI-, the three-dimensional effect is reduced because the physical distance between the eyes is very small (approximately 6 crn).

Therefore, in the camera of the present invention, the three-dimensional effect is two-dimensional.
This can be increased considerably by increasing the separation distance between the two optical assemblies 12,13.

This assembly is moved together with the image analysis assembly.

Therefore, the effect called excessive stereoscopic display can be achieved by the will of the operator from a manual control vessel.
It can also be arranged in automatic correlation with the remote servomechanism described above.

On the other hand, when the human eye is fixed on an object at a very close distance, the binocular distance of about 60 mm often requires the said optical device to reduce the excessive stereoscopic effect and provide a comfortable stereoscopic effect without exaggeration. A mechanism for separating the optical devices 12 and 13 may be provided in addition to the function of moving the optical devices 12 and 13 one position from each other.

The camera of the invention has two telemeters.

That is, each of the optical assemblies 12.13 always maintains an equal focal length, and the telemeter is connected to the two optical assemblies 12.1.
The focal lengths of the three lenses are sufficiently synchronized so that they remain equally varied and maintained at the same time. This synchronized focusing is achieved by the servomechanism described above, which drives both optical devices simultaneously and synchronizes their movements. Eyepiece 1
0.11 is binocular so that the operator can observe the stereoscopic screen.

In fact, the camera of the present invention is composed of two cameras,
One camera is for the left photogram, the other for the right photogram. However, this camera is included in the same case or device designated by reference numeral 1.

The angular adjustment of the two optical assemblies 12.13 is controlled by said servomechanism operating at a remote distance indicated by an automatic or manual telemeter mounted on each assembly; this control is as described above. Also, in a manner similar to strabismus in the human eye, changes in focal length due to the depth of focus of the field of view and angles that adapt the direction of the line of sight of two optical assemblies to a point regardless of the distance at which they are placed. Synchronize everything, including both position changes.

Each optical assembly perceives an object, and if the camera is for a color television, the light beam reaches three color filters, passes through an image analysis tube 14.15 and a frequency filter O.
It then reaches the device designated by number 2 in FIG. Of course, when the camera is for black and white video, only one video analysis tube is used for each optical assembly, but the operation is exactly the same as for color television. In the receiver, these switched-on image signals are intercepted on the image tube by a mosaic of alternating vertical straps, all of the same width and extremely narrow; alternately left strap, right strap, left strap, etc., as indicated by reference numerals 18 and 19 in FIG. 5 of the drawings.
Form... FIG. 5 shows a representative example of an image screen 16 on which the vertical straps are fed by transmitters, as described below in connection with system electronics. It is given by the following image signal.

The audio of Sostem may be monaural or stereo, but in this application, a stereo system is used. This is because this method increases the degree of three-dimensional discrimination with the naked eye,
This is because adding stereo audio to stereo vision creates an overall three-dimensional effect.0 The stereoscopic image formed by alternating vertical struts, by itself, gives the viewer the perception of a three-dimensional image. It is not possible. This is shown in FIG. 5 of the drawings in conjunction with an image screen 16 which includes vertical straps 18 and 19 for the Ishikawa signal.
The series of alternating stereo straps on the image screen 16 are viewed binocularly. In order to perceive three-dimensional signals, it is essential that the right eye only sees what corresponds to the Ishikawa image and not what corresponds to the pressure image, and vice versa. It is. In other words, each human eye must only perceive its respective image strap 18 or 19 and not the opposite image.

The image signal sent by Transmitsuku Yuuko is 2
These are divided into two stereo images numbered 18 and 1.
It is divided to form alternating narrow vertical straps forming an alternating zeta mosaic pattern on the image screen 16 as shown at 9. These alternating straps may be separated by a transparent EXOGRAPH™ screen 17 as shown in the fifth column.

The exograph screen must be placed in front of the imaging electron tube. Furthermore, the image electron tube may be for three colors, that is, for color television, or may be for monochrome, that is, for black and white television.

This exograph screen is made up of semi-cylindrical lenses arranged in a continuous array in the vertical direction, and has the same width as a pair of strumps of the imaging electron tube. As shown in Fig. 3, it is concentrated sufficiently to span the pair of struts.

Given the relative spacing of human eyes, each viewer's eye looks through the cylindrical lens from a different angle. Therefore, depending on the relative positions of the semi-cylindrical lenses, the right eye sees the Ishikawa image and the left eye sees the pressure image. This means that the light is refracted by each of the semi-cylindrical lenses,
This is because the light is emitted from the optical axis 1, as indicated by numbers 23 and 24 in FIG. 6 of the drawings. 6th
In the figure, a pressure image 18 and an Ishikawa image 19 pattern appear on each of the straps 18 and 19, respectively, and each of the straps 18 and 19 is surrounded by a single semi-cylindrical lens 20 of the screen 17. Therefore, the semi-cylindrical lens is Ishikawa's image strap 1.
The ray coming from 9 is numbered 24 in Figure 5 of the drawing.
bend it to the right as shown in . On the other hand, the semi-cylindrical lens 20 refracts the light beam from the pressure strap 18 in the angular direction indicated by 23 in the drawing. In this way, two different images are formed, namely light beams 23 and 24, which can be perceived separately by both eyes, the left eye receiving and admitting light ray 23, the right eye receiving and admitting light ray 24, and Each of the light rays presents a different stereoscopic image to the viewer's eyes.

Etagraph screens formed in accordance with the present application may be made of a rigid or elastic material so as to be spaced to accommodate the width of the vertical straps 18 and 19.
Ru. Then, when the incoming signal is not a stereoscopic image, the exograph screen must be removed by folding it into a rolled or stretched state. It is done using electrical pulses carried within an arbitrary width of the bandwidth of the image signal from the transmissor. (Hereinafter, blank space) The stereoscopic screen television according to the present invention is, for example, NTSC.

The circuit is arranged in accordance with international standards for signal transmission and conduction, such as the PAL and SECAM systems, and the signal is transmitted by air, cable, carrier wave, Sent via satellite, etc.

In order to have a clearer understanding of the basic power and reservation arrangement of the system of the present invention, reference will be made to Figures 7.8.9 and 10. According to the above figures, particularly FIG. 7, when the camera 12) optical assembly perceives different images, namely right and left images, these images are converted into video signals 25 and 26. These video signals 25 and 26 are switched by a high speed analog switch 2 and are passed alternately at divided time intervals. These video signals 25 and 26 also contain the equivalent of right and left information. The switching system described above actually operates at a frequency twice the horizontal scanning frequency currently in use, for example 3,500 (2X 15,750) H in the NTSC system.
It has a digital clock operating at z, a flip-flop 30 which alternately transmits logic 1 to output terminals 34 and 35 at the same frequency as the horizontal deflection (15750 Hz) in the NTSC system, and electronic contacts 36 and 37. Thus, the receiver consists of two pairs of analog switches 2 which are normally open when the input control signal is a logic zero. As shown in FIG. 7, the left video signal 26 and the right video signal 25 are connected to each flip-flop 3
It is controlled by control signals sent out via output terminals 34 and 35 of 0. The operation of the above video signal is shown below.

The first left video signal 26 appears at the output terminal 39 of the analog switch 2 with a waveform as shown by the left graph Vo in FIG. 8(B). That is, the left control signal 3
5 is a logic one, while the cloth control signal 34 is a logic zero, so the wavefront 42 of the above waveform appears. This means that the electronic contact 37 of the analog switch is in its closed position, whereas the electronic contact 37 of the analog switch is in its closed position.
By keeping 6 open, the right video signal 25
This will definitely block the . At the same time, the right video signal 25 does not appear at the output terminal 39 of the switch 2, as shown by the right graph Vo in FIG. 8(C). This is because the signal simultaneously exhibits the troughs of the waveform.

Contrary to the above, the right control signal 34 is
0, the left control signal 35 will be a logic zero;
The electronic contacts 36 of the switch 2 are in their closed position and the electronic contacts 37 of the switch 2 are in their open position. Due to this, the eighth (

pass through.

Since the output terminals of either one of the contacts of the electronic switch 2 are connected together to one signal output terminal 39, as shown at 40 and 41, as a result,
The switched video signal is shown in graph V of FIG. 8(D). This is obtained as a line 39 as shown in .

Clock 29 is connected to flip-flop block 30 via line 33.
is connected directly to the input terminal 33 of the flip-flop 30, so that a constant period control pulse alternately switched between the signals 35 and 34 is sent to the flip-flop 30 by the clock 29. It is obtained when one cycle of the wave is passed. However, the condition is that the input terminals 32 and 31 of the flip-flop are maintained in a logic 1 state. (Margins below) Figure 8 (A) (

The above meaning is, for example, the time t1 of the left control signal shown as reference Nn42 in Figure 8(B).
is a logic number 1, and on the other hand, the time t of the right control signal indicated by 44 in FIG. 8(C) is a logic number 0, and these form a pair. That is, the left control signal 43 is O, whereas the right control signal 4
5 is 1, and from this, the time t of the left video signal 46 is obtained as shown in Figure 8 (b), and the time t2 of the right video signal 47 corresponding thereto is obtained.

The television transmission station converts the stereo program signal into a video signal and transmits it by air, wire, carrier, or similar methods well known in the art.

If the camera 1 of the system of the present invention is used as a transmission program without stereo images, the signal is used as a receiver of one of the two optical systems including the camera 1. Then, the bypass switch 2 of the present invention as shown at 38 in FIG.
The video signal would be sent for direct modulation of the transmission system. In this particular instance, clock 30 is prohibited.

If the above electrical circuits associated with Figures 7 and 8 are used with the proviso that an effective conversion is required for both the camera and the television receiver, the NT
SC: Considering the system, the scanning of the beam of the stereo camera scans 525 lines, and conversely, when using a system without stereo images, it is shown as 49 in Figure 9 above the video screen 48 of the receiver. At the horizontal line instead of the vertical arrow in the drawing, the frequency is 15,570 Hz for vertical stereo scanning, compared to 60 Hz for stereo horizontal scanning.

From an electrical point of view, it is possible to use the same deformation coil as current cameras, and it is also possible to apply the horizontal deformation signal of the vertical coil and the vertical deformation signal of the horizontal coil. If the vertical distortion signal were applied directly onto the stereo system coil, an undesirable configuration (such as 4 units high and 3 units wide) would result. The configuration of the screen of the stereo television camera is the same as that of the television camera that has been used previously (width: 4 units and height: 3 units). To obtain the actual configuration of the screen, the horizontal deformation coil 50 shown in FIG.
The generated signal is received by and amplified by a linear amplifier 55 included in the circuit, and the signal reaches the contact 6o of the switch 54 and then passes through the deformation coil 50. At the same time, the vertical deformation coil 52 receives the output signal from the horizontal amplifier 51, which is reduced by the proportion of the pile, and achieves its purpose by reducing the voltage through the resistor 57 containing the corresponding output of the amplifier 512). The signal of the resistor 57 is connected to the contact 61 of the switch 56.
and from there is sent to the deformation coil 52.

When this device is used for non-stereo conversion, the camera operator must close contacts 5 of switches 54 and 56, respectively.
8 and 59, and then this operation is eliminated. (Left below) The receiving device is the first one for the camera.
The rectifier circuit for obtaining proper deflection is exactly the same as the rectifier circuit shown in Figure 0, and is tightly synchronized both in stereo and non-stereo programs, and this synchronization effect is independent of the bandwidth freedom of the emission. is obtained by electrical pulses within one of the following frequency ranges.

While the circuit described above provides the best resolution for image transmission, other embodiments of the invention also provide horizontal scanning, such as is currently used in conventional conventional TV transmission and reception systems. The circuit shown in FIG. 10 can be omitted by providing a camera and a receiver with a system that provides the following. That is, the scan shown in FIG.
Rather than a vertical scan forming line 49, it is a horizontal scan perpendicular to it.

In this particular case, the rectification system is formed by the same digital clock 29, except that said digital clock (see Figure 7) is twice the frequency of the subcarriers, for example 2X in the NTSC system.
3,579545 Mhz, i.e. 7,159'09
Flip-flop 30 is formed with the proviso that it operates at 0 Mhz.
．． 1 at each of outputs 34 and 35 at a frequency equal to the frequency of the subcarrier, which is 579,545 Mbz.
Two logic signals are sent out alternately. This is high speed switch 2
The rest of the circuit of Figure 7 is exactly the same, the only difference being that the circuit of Figure 10 is The deflection coil in the figure is omitted. However, the high speeds required for flip-flops, clocks, and switches make these goals somewhat more difficult to achieve, and the fineness and resolution of this system exceeds that of the first embodiment of the invention. Although the embodiment described above includes a modification/stem for the deflection coil, still both embodiments of the invention, as is clear from the above description, Scree.

Considering the semi-cylindrical lens placed between the surface of the object and the user's eye, it can be implemented in a highly efficient manner to obtain a stereo signal that can be perceived by the human eye in a three-dimensional pattern.

As is well known in the transmission of TV images, in some areas the reception is not completely accurate and therefore the adjustment pattern of the image on the screen of the image tube and the convergence of the image may be affected by the semi-cylindrical lens of the Kutugraph screen 17. It may happen that the accuracy is insufficient to match the position required for refraction of light. However, this problem does not occur in practice with the cable transmission of TV signals, but very frequently in areas where TV transmission is carried out via air carriers, satellites, etc., and is thereby subject to similar problems as automatic voltage regulators. It is always preferred to equip both the camera 1 and the receiver 4 of the system of the invention with automatic pattern and convergence adjustment controls, and also to divide the band containing the left-hand and right-hand images into a semi-cylindrical shape. It is further preferred to provide the receiver 4 of this system with an automatic or manual horizontal position control, preferably with a precision tuner, for alignment with the lens.

This ensures that the pattern received by the image tube is perfectly adjusted in length and width, and that the convergence of the image, especially the color image, is accurate, thereby providing the perception of a complete three-dimensional image by the user of the TV receiver. ensure that the goal of obtaining In addition, the adjustment control of the horizontal position of the image is
Adjusted by the user to precisely position the vertical band containing the left and right images in the position shown in Figure 6, in combination with the semi-cylindrical lens of the Kutsugraph screen to obtain maximum image resolution and stereophonic sound. can.
