1. An image processing device comprising: processing degree setting unit operable to set a target degree of color processing with regard to at least two properties of a plurality of properties of an image signal, as a single target processing degree; processing coefficient group creation unit operable to create a processing coefficient group for performing the color processing of the target processing degree, based on the target processing degree that is set by the processing degree setting unit and a plurality of base coefficient groups that perform the color processing to differing degrees; and color processing execution unit operable to perform the color processing with respect to the image signal using the processing coefficient group that is created by the processing coefficient group creation unit.
