Description

[0001]
[Prior art]
Images of current television systems are transmitted in a predetermined frequency band from a central office or a television station by different known means such as, for example, cables, optical fibers or radiated electromagnetic waves. Depending on the transmission means, the television device receives the television channel signal and the frequency assigned thereto via a cable or electromagnetic waves.
[0002]
So far, to form a television program, a television camera is focused on a scene, the light is converted to an electronic video signal, this video signal is combined with an audio signal, and this composite signal is transmitted as described above. I do.
[0003]
Currently, a television camera has three basic parts: a single optical system that captures images, a collector device that converts the images into electronic video signals, and an encoder that encodes the signals for transmission. And
[0004]
The process of capturing, encoding, transmitting, receiving, decoding, and displaying an image in this manner has been performed first experimentally since 1925, and then practically used worldwide. As a result, black-and-white images were obtained in the 1940s, and a dramatic first step toward realizing color television was achieved in the 1950s.
[0005]
A method of transmitting a video signal and an audio signal (transmission by an electromagnetic signal, an artificial satellite, a microwave, or a cable) in this manner has been adopted in televisions to date. For this reason, television is a compound word of tele meaning remote and vision meaning vision. To date, this transmission scheme is the most used communication means worldwide.
[0006]
The image obtained in this way is a monoscopic scope image having only two planes. In other words, this image is viewed from only one direction since a single lens of the camera is obtained by sweeping the sensor area in the vertical and horizontal directions. This is the same as viewing a human with only one eye open, and thus forms a three-dimensional object, such as depth or the distance between one object and another in the same plane. Some of the features are lost. As a result, the observation object gives a flat impression.
[0007]
The Applicant has developed a series of new devices that are comparable to stereoscopic vision, one of the most prominent features of humans, as a way to dramatically change the way television signals are transmitted to date.
[0008]
The technology proposed by the applicant is completely different from all those developed to date. This is because the technique proposed by the present applicant does not use the illusion of the human eye and does not use a polarizing lens. The technique provides a three-dimensional television system that includes image capture, processing, encoding, transmission, reception, and decoding. Applicants desire to protect the technology through patent applications. Because to date, no one has proposed three-dimensional television transmission with this new technology, which will effectively change the way humans communicate with each other.
[0009]
[Description of the Invention]
At present, the video image capture system is performed by a monoscopic camera 1 of the type having only one lens. In a typical television system, each image is encoded, and the encoded signal is transmitted, received, and decoded. Thereby, the impression of the image becomes monoscopic. In other words, the depth of the object displayed in the image is recognized in two horizontal and vertical planes.
[0010]
According to the present invention and the novel technology proposed by the present applicant, three-dimensional television signals can be transmitted and decoded. The present invention is described below with reference to the drawings and block diagrams.
[0011]
The present invention has three basic parts. That is, the three-dimensional camera 2, the signal decoder / receiver 7, and the three-dimensional viewfinder 6. The present invention requires only a conventional television signal transmission system.
[0012]
The image is photographed by the stereoscopic camera 2, transmitted to a decoder / receiver (decoder receiver) 7 by any appropriate means, and displayed stereoscopically by the viewfinder 6. This displayed image gives a three-dimensional impression (FIG. 1).
[0013]
[Detailed functions]
Two video images taken simultaneously using a stereo camera 2 that simultaneously captures video images from two lenses and two collectors that are positioned at an interval equal to the average distance between human pupil centers, Obtain simultaneously for each collector (FIG. 5).
[0014]
These images are collected, processed, and encoded independently of each other for the left and right channels using known methods and techniques (FIG. 5).
[0015]
After both signals have been processed, they can be recorded by two cooperating recording systems of analog or digital type, or in real time on any channel by two conventional transmission systems or other suitable means available. Can transmit both signals (FIG. 6).
[0016]
For example, it is possible to execute processing in a stereoscopic camera based on an existing system such as an encoding, amplification, transmission and modulation system. Both signals can be transmitted separately but simultaneously, using two different frequency transmission systems, for example two conventional television channels such as channel 5 and channel 7 or channel 7 and channel 13.
[0017]
The dual decoder 7 has two built-in tuners, one for each visual channel (left and right). Each tuner receives a signal on one antenna transmission channel 10, such as channel 5 and channel 7, for example. Both signals are separately received and decoded as left and right signals 11, respectively, and transmitted to respective screens in the viewfinder (FIG. 9).
[0018]
The viewfinder 6 is formed by a liquid crystal screen or an active pixel having a magnification function. Both screens are connected to the left visualization channel 8 or the right visualization channel 9, respectively, and are arranged in the viewfinder. Thus, when the viewfinder is mounted, the image displayed on one liquid crystal screen or active pixel screen is located in front of each eye. These screens are similar to the screens currently used in compact video recorder cameras. Similarly, it has a stereotype audio system currently used in television and consumer electronics, and decodes audio signals with this system (FIG. 9).
[0019]
All circuits in the viewfinder and decoder are powered by long-lasting lithium ions (FIGS. 8 and 9).
[0020]
Once both signals are transmitted simultaneously in the stereo camera, received by the decoder (FIG. 9) and displayed in the viewfinder (FIG. 8), the user's brain can directly see what the user's eyes are several kilometers away. As in the case of FIG. 7, the right image 3 and the left image 4 are superimposed.
[0021]
Such a three-dimensional effect is obtained when the human brain decodes signals from two unrelated sources (each source is each eye). That is, in this case, by viewing a certain object from two different viewing angles, a human can recognize the depth and distance of the object being viewed. This stereoscopic vision 5 is obtained by the brain superimposing or combining the images received by each eye.
[0022]
The present invention is completely different from systems developed to date. This is because the existing three-dimensional transmission technology and the polarized images used to date require the use of mica or ordinary lenses instead of polarized lenses. Also, two unrelated cameras, each having a polarizing lens, can create an illusion in the human visualization process by transmitting images taken from two different angles at high speed, thereby causing discomfort, headache and fatigue. Cause. On the other hand, in the present invention, a continuous image can be obtained simultaneously in real time without causing an illusion to the brain. Therefore, no symptomatic symptoms occur.
[0023]
The present invention also differs from computer generated virtual reality digitized images. That is, such an image is, after all, a generated simulation and does not display real information of the image.
[0024]
The most important point of this new integrated technique is that not only can the effect corresponding to the observation be obtained, but also that the depth of the transmitted object can be recognized. As a result, even if the shooting site is a few kilometers away, the user can feel as if he is physically at the shooting site.
[0025]
The effect of making the user feel as if he / she is physically at the shooting site has not been obtained by any technique until now. The benefits and applications directly derived from this technology are enormous. Here are some examples. Remote surgery can be performed in three dimensions. Remote operation becomes possible. Watch soccer games from a distance. Live program transmission can be performed in three dimensions. Commercials can be recorded in three dimensions to obtain the exact features of the product, and these features can be transmitted by the techniques of the present invention. You can get the feeling as if you were accompanying a trip. You can hold a video conference. It is possible to recognize all the details of a three-dimensional object in a space.
[0026]
As mentioned above, three-dimensional video transmission is a revolutionary invention that has not heretofore been provided by any communication means or technology company, and the claimed claims are the sole property of the applicant Shall be.
