    amplifying means for amplifying said one input image signal so as to provide identical first and second image signals and amplifying at least one of the first and second image signals in conformity with a difference in brightness between a relatively bright area and a relatively dark area of an image represented by the one input image signal;

    discriminating means for discriminating a boundary between the relatively bright area and the relatively dark area of the image; and

    synthesizing means for producing a composite image signal using the first image signal obtained from said amplifying means with regard to the relatively bright area and the second image signal obtained from said amplifying means with regard to the relatively dark area, said relatively bright and dark areas being demarcated by the boundary discriminated by said discriminating means.
