Abstract
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.
