A communication light detecting device interconnecting light transmission paths and collocated therebetween, comprises: an optical coupling body including a core portion for photo coupling with the light transmission paths, and a light extracting portion for extracting a part of the communication light as a leakage light; and a light detecting portion having a light receiving member for receiving the leakage light. The light extracting portion is preferable to possess a lower refractive index than that of the core portion. Besides, the light extracting portion is preferable to include a light detecting use groove with a groove width of 50 μm or more and 140 μm or less formed by cutting and separating the core portion. Besides, the light extracting portion is preferable to be the optical coupling body in which outer diameter of the core portion is different from the outer diameter of a core of the light transmission path.

A video signal processing device displaying both image and process information includes multiplexing circuitry for multiplexing a second video signal with a first video signal. Control circuitry is provided for controlling a multiplexing ratio of the first and second video signals in the multiplexing circuitry. A display is provided for simultaneously displaying at least a part of a video image which corresponds to the first video signal, and also for displaying a state of the multiplexing operation being performed by the multiplexing circuitry under the control of the control circuitry. Preferably, only a peripheral portion of the image is faded in the view finder. Alternatively, a bar graph on the side of the image in the view finder indicates the degree of fading the image is subjected to.
