[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for processing an image photographed by a television camera, for example, by photographing an optical fiber connected by an optical fiber fusion splicer by the television camera and monitoring the television monitor.

2. Description of the Related Art When an optical fiber fusion splicing device is used to splice two optical fibers by abutting ends thereof, the two optical fibers are photographed by a television camera, and the images are processed by an image processing device. The optical axis of each optical fiber is detected, and one or both optical fibers are moved based on a signal from the image processing apparatus to automatically position the optical axes of the two optical fibers. There is. One example is an optical fiber fusion splicer shown in FIG. As shown in the figure, this apparatus has positioning pedestals C and D for separately setting two optical fibers A and B, and a television for photographing the optical fibers A and B set on the positioning pedestals C and D. A camera E, and an image processing device F for processing an image from the television camera E, and the positioning pedestal C,
One of the pedestals C is automatically controlled and moved based on a signal from the image processing apparatus F, and the image processing apparatus F observes the captured images of the optical fibers A and B. The optical fibers A and B can be observed on the television monitor G by connecting a television monitor G for performing the operation. 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 across the positioning pedestals C and D, and two optical fibers A are provided at the tip of the television camera E. , B are mounted with a microscope J for enlarging and photographing the butted portion.

In the optical fiber fusion splicing apparatus shown in FIG. 15, the resolution of the optical fibers A and B in the direction of the axis shift is increased.
In order to enable high-accuracy axis alignment, as shown in FIG.
The television camera E is set so that the scanning line direction is perpendicular to the optical axes of the optical fibers A and B, and the images of the optical fibers A and B projected on the television monitor G are made coincident with the photographed images, thereby causing visual confusion. In order to avoid this, the television monitor G is also set by rotating it 90 degrees (in an upright position) as shown in FIG.

However, the optical fiber fusion splicer shown in FIG. 15 has the following problems. 1) Television monitor G rotated 90 degrees to portrait orientation
Is inconsistent with human vision, causing a sense of incongruity to workers,
May cause fatigue. 2) As for the text and graphics information that can be displayed on the TV monitor G, when the TV monitor G is rotated by 90 degrees, the display area in the horizontal direction becomes narrower, so the number of displayed characters per line decreases, and the same sentence can be displayed. The large number makes it difficult to read. 3) As is well known, the television monitor G of the aperture grille tube has a flat surface in the vertical direction even if the screen is curved in the horizontal direction. However, if it is used by rotating it 90 degrees, its advantage is lost. 4) In the latest display devices typified by liquid crystal displays and plasma displays, the physical characteristics of the elements and the viewing angle range are given in a direction to match the visual field by an externally provided non-reflection filter or coating layer. The advantage is lost when rotated by 90 degrees. 5) The above problems also cause a reduction in work efficiency and also lead to delays in optical fiber network construction, which often plays a key role in a communication network.
