A color signal processing circuit comprising an amplification circuit having three gains for amplifying a color signal of red, green and blue color signals and amplifying the red, green and blue color signals, the red, green and blue color signals being generated from an image signal taken by a solid-state imaging device by a color separation; a pull-in determination circuit for judging whether or not the color signal in a two dimensional coordinates for defining the color is positioned within a first pull-in limit region showing a color adjustment region and a second pull-in limit region defined in the first pull-in limit region and contained an origin of the two dimensional coordinates, and determinating the pull-in of a color shown by the color signal into a white color defined as the origin of the two dimensional coordinates; and a gain adjustment circuit for adjusting the gain of the amplification circuit, to thereby pull-in the color shown by the color signal determined the pull-in into the origin of the two dimensional coordinates.
