JPS59223079A - Transmitting device of picture image - Google Patents

Abstract

PURPOSE:To simultaneously take in plural pieces of video and to easily take images even into a narrow or complex place by utilizing the fineness and flexibility of an image guide, by connecting the image guide branched into plural parts at the image picking up side with a television camera after the image guide is tied up in a bundle at the image receiving side. CONSTITUTION:The picture image transmitting device of this invention is made by tying up optical fibers in one bundle for transmitting picture images and can be bent freely to a fair extent (with the bendable radius depending on the material) except both end parts. This system is an example of a system which simultaneously takes four pictures in one television camera. The image guide of this system is branched into four parts at the image picking up side and four pictures are respectively taken in the four image guides. The four image guides are tied in one bundle at the image receiving side and connected with the image receiving section of the television camera 3.

Description

[Detailed description of the invention] 〔Technical field〕 This invention relates to image transmission technology.

[Background technology]

An image guide is a bundle of thousands to tens of thousands of optical fibers and is used to transmit images. Image guides differ from light guides made of the same optical fibers in one way.
A single fiber is arranged regularly on the end surface, and the individual fibers are matched at both ends, so that the image reflected on one end is reflected exactly on the other end surface.

The advantage of this image guide is that the end surface is fixed, but
The other parts can be bent freely, which is useful in narrow or complicated places.

This has been used as a medical gastrocamera, and has recently begun to be used for industrial purposes as well, but it is still used only for viewing images, and is not used much for measurements or pattern recognition. It's not.

On the other hand, in cases where a TV camera cannot directly enter the measurement location, or where it is desired to separate the TV camera from the measurement location, ordinary lens systems have many limitations and are difficult to use. Ta. Furthermore, capturing multiple images simultaneously with a single television camera required a complex optical system.

[Purpose of the invention]

This invention aims to simultaneously transmit multiple images of areas that are difficult to bring into the television camera.

[Disclosure of the invention]

In order to solve the above problems, an image transmission device according to the present invention is characterized in that an image guide which can be branched into a plurality of parts on the naked image side is bundled into one on the image receiving side and connected to a television camera.

The present invention will be explained below based on illustrated examples.

An embodiment of the present invention is shown in FIGS. 1 to 5. FIG.

An outline of the image transmission device according to the present invention is shown in FIG.
As mentioned above, the image guide f11 transmits images by bundling optical fibers (2) as shown in Figure 2, and can be bent quite freely (the radius of bending is determined depending on the object) except for both ends. be able to.

This system is an example of a system that captures four images at the same time with one television camera, but the naked image side is branched into four image guides, and four images are captured by each of the four image guides. On the image receiving side, the four image guides (1) are bundled into one and the TV camera (
It is connected to the image receiving section of (b).

As shown in FIGS. 2 and 4, each image guide (1) is composed of optical fibers (1) bundled through a cladding (4) so as to form a substantially rectangular bare image surface. Each of the image guides (1) is bundled into a single fiber on the image receiving side as shown in FIG. 5, and the image receiving surface of the bundled optical fibers (1) is shaped like a square. Each field-shaped image receiving surface corresponds to each image guide (1).

The image (6) captured by the television camera on the image receiving surface of the image guide (1) is displayed on the monitor screen (5) in a square shape as shown in FIG.

In this way, the images (6) captured by each image guide (1) are displayed independently on the monitor screen (5).

〔Effect of the invention〕

As described above, according to the image transmission device according to the present invention, it is possible to capture a plurality of images at the same time, and by utilizing the thinness and flexibility of the image guide, the tip of the image guide can be used even in narrow or crowded places. By setting the , you can easily capture images. Furthermore, since it is a fiber, it can be set up away from the television camera, and even if the television camera is fixed, the observation position can be changed within the reach of the image guide.
