An image-information obtaining unit obtains image information. An image-component separating unit separates the image information into luminance information and color information. An edge extracting unit extracts edge information from the luminance information. A luminance-noise removing unit removes noise from the luminance information. A color-noise removing unit removes noise from the color information. An image-information synthesizing unit synthesizes image information based on the edge information, the luminance information form which the noise is removed, and the color information from which the noise is removed.
