Abstract
An image display system, in which a display image of a monitor of the first scanning system is taken by a TV camera of the second scanning system to pick up video signals to be displayed on a monitor of the second scanning system. The output of the TV camera of the second scanning system is multiplied by a factor.alpha. (.alpha. is any real number satisfying 0<.alpha.<1) in a first multiplier. This multiplication result is added together with another input value in an adder. The output of the adder is stored in a frame memory. One frame of video signals read out of the adder is multiplied by another factor (1-.alpha.) in the second multiplier. The first and second multiplication results are added together in the adder, and the addition result is returned to the frame memory as feedback. As a result, the video signals output from the TV camera are averaged to prevent an offensive image to the eye of the display.
