In order to simply and easily implement an elimination of a color deviation and a color adjustment for a color correction to a favorable color in an arbitrary portion of a color region in a color reproduction range, a video processing circuit 2 corrects a luminance, a saturation and a hue of a color by the correction quantity corresponding to a reference correction coefficient with regard to a signal value of an input video signal indicating a color within a designated color region defined by a designated range of the luminance, the saturation and the hue when the color indicated by the signal value is a color in the center of the designated color region or at a core for occupying a predetermined range around the center. Otherwise, the video processing circuit 2 corrects the luminance, the saturation and the hue of the color of the signal value by the correction quantity gradually smaller as a position in a color space of the color indicated by the signal value approaches a boundary position of the designated color region.
