Description

[Detailed description of the invention]

The present invention relates to an image capturing, transmitting, and reproducing device that can display clear images on a large screen. For example, when inspecting an object or conducting an IN festival at a distance, it is possible to take an image of the object and display it! i! A technology that converts signals into signals and transmits them to a receiver to play back video is widely talked about. When the object is large, the reproduced image 12 is displayed in a large size because it is impossible to distinguish minute parts if it is small, but currently known cathode ray tubes, liquid crystal panels, and Not only is there a limit to the size of the display screen of luminescent and cathode ray tube receivers that have image playback functions, but large receivers also make the images unclear, making it difficult to conduct accurate inspections and in-depth observations. . Therefore, as shown in FIG. 4V), images WBt, Bz are taken by the TV camera facing the object A. B3. A plurality of B4 units are arranged at appropriate intervals, each image a part of the object A, and the transmitter C adds a synchronization signal to each video signal and sends it to the receiver, where the imaging tube B1 and
...Multiple receivers El arranged corresponding to B4
, E2, E3, and E4, a portion of the image is displayed on each display screen as a whole, and the image of the object A is reproduced. Problems to be Solved by the Invention In the technique shown in FIG.
By increasing the white sand of the image receivers E1...E4, even a large object A can be displayed as a large and clear image. However, the work of adjusting the focus of each image pickup tube B1...B4 is extremely troublesome, and it is necessary to image each image pickup tube by increasing the number of M times each other to avoid blank areas. Therefore, as shown in FIG. ...The display surface of E4 each forms a pixel, and these form a single image 3 as a whole, but the display surface of E4, such as a cathode ray tube, etc.
・E4 has a frame that structurally surrounds the display surface. Further, the display surface has a functionally effective surface and an ineffective surface around which no image is displayed. Therefore. FIG. 4 (As shown in C1, each effective surface F1...
It is unavoidable that there is a blank area G consisting of a frame and an invalid surface between F4, and when one image is displayed as a whole, this will be divided by the blank area G, which will hinder inspection and observation. Therefore, the present invention solves these problems. The object of the present invention is to provide a photographing, transmitting, and reproducing device that can reproduce and display an object as a whole into one complete and clear image. The present invention provides reduced il! (iii) optical means for converting the bundle into a plurality of optical fibers, a plurality of optical fiber ends whose end faces are arranged substantially without gaps to form a single incident surface of the image, and each of the other end faces of the optical fiber bundle; a plurality of image pickup devices whose image pickup surfaces face each other; a transmission means for transmitting a video signal generated by each of the image pickup devices to the corresponding plurality of image receivers; and one end surface facing each display surface of the image receivers. The above-mentioned problem is solved by providing a configuration in which a plurality of optical fiber bundles are arranged, and the other end faces of the optical fiber bundles are arranged side by side with almost no gaps so that the image is displayed on one screen. I used it as a last resort to solve the problem. When images reduced by optical means are incident on a plurality of optical fiber bundles forming a single input surface, a portion of each of the two images optically passes through the bundle and reaches an image pickup device. The images captured on each imaging surface are sent as video signals to the corresponding multiple receivers, and are displayed as images on their display surfaces. These images are further passed through an optical fiber bundle and displayed on one screen as a complete image with no blank areas. According to the present invention, even a large or distant object can be imaged clearly and unbroken on the entrance plane of an optical fiber bundle by optical means.

In addition, since the image is divided into parts and sent by another set of optical fiber bundles and displayed on a single screen, the image is faithfully reproduced in a perfect state with no blank areas. is obtained. In addition, since multiple optical fiber bundles were used, by increasing the number of optical fiber bundles used, Osugi's object could not only be clearly displayed on a large image. The image pickup device and the image receiver are compact and have high definition, and the end surfaces of the optical fiber bundles are opposed to their effective surfaces so that each portion of the image can be transmitted and reproduced in its entirety. Furthermore, according to the present invention, the camera and the camera can be installed at any location without being adjacent to each other, and since video signals are transmitted between them, the spatial relationship between the object and the screen can be changed. It can be freely set, and can be easily inserted into means such as image processing by a computer, image recording by a recording machine, and aerial transmission by a communication system to increase its utility value.Example 1 is shown in Figure 1. This shows an embodiment of the present invention, in which an optical means 1 consisting of a lens system is disposed facing an object A to be inspected so as to be movable in the axial direction, and a plurality of optical fiber bundles 2 are arranged. A single entrance surface 3 formed side by side with almost no gaps on one end plane is arranged behind the optical means l.The entrance surface 3 is either fixed or aligned along the same axis as the preemptive means 1. It is said to be movable in the direction,
The object A enters the entrance surface 3 as an image reduced by the optical means 1. and a plurality of imaging devices 4 each consisting of a television camera. An amplification/processing circuit 5 of a double-view stand that processes the video signals obtained from these, and a collective circuit 6 that converts each video signal into one video signal are installed, and the imaging surface 4a of the imaging device 4 is effectively surface. That is, the other end surfaces of the respective fiber bundles 2 are arranged so as to face the photocathode so as to be substantially in contact with each other. Therefore,
The image incident on the entrance surface 3 is divided into parts and passes through each of the optical fiber bundles 2, and reaches the imaging surface 4m, where the image captured there is converted into a video signal by the imaging device 4.
Furthermore, each video signal passes through an amplification/processing circuit 5 and is transmitted as a single video signal to which a synchronization signal is added in a collective circuit 6. A distribution circuit 8 to which the video signal transmitted from the collective circuit 6 is sent, and a receiver 10 consisting of a number of television receivers corresponding to each image pickup device 4 are installed, and an amplification/processing circuit 5. Collective circuit 61 distribution circuit 8. A cable 7 connecting these constitutes a transmission means 9 for transmitting a video signal from the imaging @4 to the receiver 10. The distribution circuit 8 divides the video signal generated by each of the image pickup devices 4 again as it is and distributes it to the corresponding receiver 10. One end of an optical fiber bundle 11 is disposed in substantially contact with the display surface 10a of the cathode ray tube of the image receiver 10, facing the effective surface thereof. The other end face of the plurality of optical fiber bundles arranged corresponding to each display surface 10m is arranged on one plane with almost no gaps to form a single screen 12. The image displayed on the display screen l(1&) will pass through each optical fiber bundle 11 and be displayed on the screen 12 as a single completed image. A magnetic wave transmitter 15 is installed to perform image processing, two-image recording, and aerial transmission. Fig. 2 shows a different embodiment of the present invention, using the same receiver as described above. A single screen 16 is formed by arranging the other end surfaces of a plurality of optical fiber bundles 11 with one end facing each of the 10 display surfaces 10a on a concave surface with almost no gaps.

A single screen 17 is formed by arranging them almost without any gaps. In the embodiment shown in FIG. 2.3, the screens 16 and 17 are cylindrical, but the eight screens may also be spherical. It is necessary to perform spherical processing.Also, when the object is not a flat surface but a curved surface, the screens 12, 16 and 17 should be made into corresponding curved surfaces, so that clear and faithful reproduction can be achieved over the entire surface. Furthermore, the transmission means 9 may be configured as desired, such as by connecting the corresponding imaging 1a 4 and image receiving (pulling 10) with separate cables, or by converting the video signal into radio waves and transmitting them in the air. Furthermore, the display surface 10& of the receiver 10 can be constructed of a liquid crystal panel, a liquid crystal panel, a cathode tube, or the like having an image reproduction function.
