Abstract

PURPOSE:To transmit exactly an image by providing an arrangement storage means for storing in advance an arrangement position relation of an optical fiber in both end faces of an optical fiber bundle, and an image converting means for converting a position of each picture element of an image which has been emitted, based on the arrangement position relation of the optical fiber in both these end faces. CONSTITUTION:An optical fiber bundle 1 is a random collection type optical fiber bundle, many optical fibers are collected irregularly and an arrangement position relation of the optical fibers in both end faces is at random. As for an image which has been made incident on an incident end face, a position relation of each picture element appears at random in an emitting end face, and the image is brought to an image pickup by a TV camera 2 and stored temporarily in an image memory 3. On the other hand, an arrangement table for showing a relation of an incident end and an emitting end is stored in advance in an arrangement memory 4, a controller 5 rearranges a position of each picture element of an image which has been read out of the image memory 3, based on its arrangement table, and when the image whose arrangement has been converted by the controller 5 is displayed on a CRT display device 6, the image which has been made incident on the incident end of the optical fiber bundle 1 is reproduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to improvements in image transmission devices using optical fiber bundles.

Conventional technology When transmitting images using a bundle of optical fibers, conventionally, as shown in Fig. 3, a regular bundle type optical fiber, in which the optical fibers are arranged in the same manner on the input end face and the output end face, is used.
It is necessary to use bundle IO. This is because if an optical fiber bundle is made by randomly assembling optical fibers, the position of each pixel of the incident image will be completely random at the output end, making the image meaningless.

Problems to be Solved by the Invention However, it takes time and effort to assemble a large number of optical fibers so that the arrangement is the same at the input end and the output end to create a regular assembly type optical fiber bundle. There is a manufacturing problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image transmission device that can transmit images even using randomly assembled optical fibers.

Means for Solving the Problems An image transmission device according to the present invention includes an optical fiber handle in which the positions of the optical fibers on the input end face and the output end face are arranged randomly, and in this optical fiber handle, Array storage means for storing in advance the arrangement positional relationship of the optical fibers on both end faces, and image conversion means for converting the position of each pixel of the emitted image based on the arrangement positional relation of the optical fibers on both end faces. It is composed of:

Using an optical fiber bundle in which the optical fiber positions on the input end face and the output end face are randomly assembled, an image is input from one end of this optical fiber bundle and an image is output from the other end. In the output image, the position of each pixel is random. However, the arrangement positional relationship of the optical fibers on both end faces of this optical fiber bundle is stored in advance, and the output image is determined based on this arrangement positional relationship. The position of each pixel in the image is transformed, so
The original incident image is reproduced.

In FIG. 1, the optical fiber bundle l is a randomly assembled optical fiber bundle. That is, in this randomly assembled optical fiber bundle 1, a large number of optical fibers are irregularly assembled, and the arrangement positional relationship of the optical fibers on both end faces is random. Therefore,
An image incident from the input end face appears with random positional relationships among pixels at the output end face. This emitted image is captured by a television camera 2 and temporarily stored in an image memory 3.

On the other hand, the array memory 4 stores an array table showing the relationship between the array at the input end and the array at the output end. Once the randomly assembled optical fiber bundle l is created (a large number of optical fibers are fixed in a gathered state), the arrangement relationship at both ends becomes fixed. Therefore, the arrangement relationship at both ends specific to this optical fiber handle l is investigated in advance, and an arrangement table prepared based on this is stored. And the controller 5 is
The positions of each pixel of the image read from the image memory 3 are rearranged based on the above arrangement table. Therefore, if the image whose arrangement has been converted by the controller 6 is displayed on the CI'IT display device 6, the original image will be displayed. (incident at the input end of the optical fiber bundle l) will be reproduced.

FIG. 2 shows another embodiment. In the above embodiment, the image with random pixel positions is stored in the image memory 3.
However, in this embodiment, the random image emitted from the output end is directly converted into a regular array without storing it in the image memory. In FIG. 2, random images of the output end of optical fiber bundle l are taken by random scan camera 7. In FIG. This random scan camera 7 does not sequentially perform readout scanning for each horizontal scanning line like a normal television camera, but can arbitrarily (that is, randomly) determine the readout order for each pixel. , the scan is controlled by the scan controller 8 based on the array table stored in the array memory 4. That is, random scan camera 7
Then, each pixel of the captured random image is sequentially scanned based on the array table showing the array relationship at both ends of the optical fiber fist handle 1. As a result, the random scan camera 7 randomly scans each pixel. The video signal is output with the position of each pixel returned to its original normal position.

Therefore, the CRT display device 6 reproduces the original image incident on the input end of the optical fiber fist handle l.

Effects of the Invention According to the present invention, there is no need to use a regular assembly type optical fiber fist handle in which a large number of optical fibers are arranged and assembled so that the positions of each optical fiber are the same at both ends, and the alignment position at both ends can be adjusted. Even if the relationship is random, images can be transmitted correctly. Therefore, it is possible to use a randomly assembled optical fiber bundle in which a large number of optical fibers are appropriately assembled, which greatly simplifies manufacturing.
