Abstract
A color signal processing device for generating image data to be displayed on a display device which represents a color by using at least four primary colors, includes an obtainer that obtains a color signal regarding three primary colors for image data composed of a plurality of pixels, a changer that changes a value of the obtained color signal regarding the three primary colors, and a converter that converts the changed color signal regarding the three primary colors into a color signal regarding four primary colors. When a predetermined region contains a color saturated pixel, the changer makes the value of the color signal of at least one color of the three primary colors smaller, for pixels contained in the predetermined region.
