IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM, CAPABLE OF VIRTUAL REPRODUCTION OF MAKEUP APPLICATION STATE

An image processing device generates a make-up image when a make-up coating material is applied to a part of a subject appearing in a source image by processing the source image. A color range of pixels forming a coating material application layer is obtained by expanding a color range of pixels composing the part of the subject by a ratio of a color representing pixels composing the subject to a color of the make-up coating material. Values of pixels of the coating material application layer are obtained by mapping values of pixels of the source image to the color range of the coating material application layer.
