Abstract

PURPOSE:To reproduce a subject image correctly even when images at the incidence and projection end surfaces of an image transmission guide have dissident position relation by processing a video signal with relative position relation among respective element wires in the incidence and projection end surfaces. CONSTITUTION:A subject image 1 is formed on the incidence end surface of the image transmission guide 3 through a lens system 2. The image appearing on the projection end surface when said image is transmitted through the image guide 3 is formed on a telecamera 6 which is rotated by a rotating device 5 through a lens system 4. The information on the relative position relation among respective element wires in the incidence and projection end surfaces of the image transmission guide 3 which is measured previously is stored in the memory of a controller 7. Then, the video signal from the telecamera 6 and the output of the controller 7 are inputted to an interface 8 and the video signal is converted by a processor into an image signal for reproducing the subject image 1 correctly, which is sent out to a television monitor 9.

Description

[Detailed Description of the Invention] [Background and Objectives of the Invention] The present invention relates to an image fiber transmission system, and particularly to an image fiber transmission system that correctly reproduces a subject image even if the positional relationship of images at the input and output ends of an image transmission guide does not match. This invention relates to an image fiber transmission system suitable for.

Conventionally, in image transmission guides, there is a trade-off between increasing the number of pixels and flexibility. That is, there is a problem in that increasing the number of pixels increases the outer diameter and generally makes it difficult to bend.

Generally, in order to improve the flexibility of an image transmission guide, it is said that it is better to twist each strand of the image transmission guide, but in the case of many pixels of 10,000 to 30,000,
There is still an unresolved problem in the technique of making the arrangement of the strands the same at both ends of the image transmission guide when the strands are twisted together. Therefore, it has not been possible to use an image transmission guide in which individual wires are twisted together in an image fiber transmission system.

The present invention has been made in view of the above, and its object is to provide an image fiber that can correctly reproduce a subject image even if the positional relationship of the images at the input and output end faces of the image transmission guide does not match. The purpose is to provide a transmission system.

U Overview of the Invention The present invention is characterized by a first optical system that forms a subject image on the short incident surface of the image transmission guide, and a second optical system that forms the image transmitted by the image transmission guide on a television camera. an optical system, a controller that inputs the relative positional relationship information of each element wire on both input and output end faces of the image transmission guide measured in advance, and a video signal from the television camera that inputs the video signal and outputs from the controller. The present invention includes a processing device that processes the video signal, converts it into an image signal that accurately reproduces the subject image, and sends the signal to a television monitor.

[Example] The present invention will be described in detail below using an actual BFJ example shown in FIG.

Figure 1 shows the image fiber transmission system of the present invention in which = 1' Embodiment 8 Rev. 70 V 'j [iJT' 6. An image is formed on the incident end surface of the image transmission guide 3, which is bundled and polished. This image is transmitted as a light intensity signal on the core of each pixel of the image transmission guide 3 and appears at the output end. The image transmission guide 3 is made of wires twisted together to form a multi-pixel structure, but several units of about 1,000 pixels are arranged in advance so that the relative positional relationship at the input and output ends is equal. You may also use one twisted together.

In these cases, the output end is also bound with resin, but the arrangement of each pixel is different from that of the input end. The image appearing on the exit end face of the image transmission guide 3 is formed by a lens system 4 onto a television camera 6 which is rotatable by a rotation device 5 . 7
(Input the relative positional relationship information of each element wire t′3t on the input/output end face of the image transmission guide 3, which has been measured in advance.)
] This is Cocon Millot. There are several methods for measuring the above relative positional relationship information. For example, an optical fiber having a core approximately equal to one pixel is used as an excitation fiber, the input end of the image transmission guide 3 is scanned two-dimensionally, and the output end face is scanned two-dimensionally. Monitor the emission position with a camera,
There is a method of inserting -=-> at the position on the output end face corresponding to the position (i, j) on the input end face. In this case, the position F
l(!, j) and (i=, j-) are stored in the memory of the controller 7. 8 is a processing interface consisting of a microcomputer;
The video signal from the television camera 6 and the output of the controller 7 are inputted, and the video signal is converted into an image signal that correctly reproduces the subject image 1 by processing the video signal as the output of the controller 7 using the processing procedure described above. , this #J image signal is sent to the television monitor 9. That is, the controller 7 and the interface 8 electrically convert the position (i-, j-) of the image on the output QJ end surface of the image transmission guide 3 into (i, j) and display the original image on the TV monitor 9. to recreate.

According to the embodiment of the present invention described above, the subject image 1 can be reproduced as the original image on the television monitor 9 even if the positional relationship of the images on the input and output end faces of the image transmission guide 3 does not match. Therefore, as the image transmission guide 3, it is possible to use a material in which the individual wires are twisted together, and it is possible to use an image transmission guide with a large number of pixels and good flexibility.[Effects of the Invention] As described above, according to the present invention, it is possible to accurately reproduce a subject image even if the positional relationship of the images at the input and output end faces of the image transmission guide does not match, and each strand is twisted together as an image transmission guide. This has the advantage of being able to use materials with good flexibility.
