BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing device for processing an image taken by a television camera, for example, an optical fiber connected by an optical fiber fusion splicing device is photographed by the television camera and then a television monitor. In addition, when the information about the optical fiber is detected from the image, the optical fiber is moved based on the information, and the optical fiber is automatically aligned, the optical fiber displayed on the TV monitor is displayed.

2. Description of the Related Art When an optical fiber fusion splicing device is used to abut and splice the ends of two optical fibers, the two optical fibers are photographed by a television camera and the images are processed by an image processing device. Then, the optical axes of the respective optical fibers are detected, and one or both of the optical fibers are moved based on the signal from the image processing device to automatically position the optical axes of the two optical fibers. There is. As an example thereof, there is an optical fiber fusion splicing device shown in FIG. As shown in the figure, this device is a television for photographing the positioning pedestals C and D for separately setting the two optical fibers A and B and the optical fibers A and B set on the positioning pedestals C and D. The positioning base C is provided with a camera E and an image processing device F for processing an image from the television camera E.
One pedestal C of D is moved automatically controlled based on a signal from the image processing device F, and the image of the optical fibers A and B taken by the image processing device F is observed. A television monitor G for performing the operation is connected so that the optical fibers A and B can be observed on the television monitor G. As shown in the figure, a light source H for illuminating the optical fibers A and B is provided on the opposite side of the television camera E with the positioning pedestals C and D interposed therebetween, and two optical fibers A are provided at the tip of the television camera E. , B for enlarging and photographing the abutting portion of B, B.

In the optical fiber fusion splicing device shown in FIG. 15, the resolution of the optical fibers A and B in the axis shift direction is increased,
In order to enable highly accurate axis alignment, as shown in FIG. 16A, the direction in which the resolution of the television camera E is high, that is,
The television camera E is set so that the scanning line direction is orthogonal to the optical axes of the optical fibers A and B, and the images of the optical fibers A and B displayed on the television monitor G are matched with the photographed image to visually confuse. In order to avoid this, as shown in FIG. 16 (b), the television monitor G is also rotated by 90 degrees (in a vertical position) and set.

However, the optical fiber fusion splicer shown in FIG. 15 has the following problems. 1) A TV monitor G that is rotated 90 degrees to a portrait orientation
Does not match the field of view of human beings
It causes fatigue. 2) For text and graphics information that can be displayed on the TV monitor G, when the TV monitor G is rotated 90 degrees, the display area in the left-right direction becomes narrower, so the number of characters displayed per line decreases, and the same text can be displayed. The large number makes it hard to read. 3) As is well known, the television monitor G of the aperture grill tube has a flat surface in the vertical direction even if the screen is a curved surface in the horizontal direction, and in a normal arrangement, there is little reflection of a fluorescent lamp or the like and the screen is easy to see. However, if you use it by rotating it 90 degrees, its advantage disappears. 4) In the latest display devices typified by liquid crystal displays and plasma displays, the physical characteristics of the element and the external non-reflective filter and coating layer provide the viewing angle range in a direction to match the visual field. If it is rotated 90 degrees, its advantage disappears. 5) The above problems also cause a decrease in work efficiency and lead to delays in the construction of optical fiber networks, which often play a key role in communication networks.
