ABSTRACT:
A storage portion stores, in association with first pixel values, table values including either gamma-corrected values obtained by performing gamma correction on the first pixel values using a predetermined reflectance component or second pixel values calculated based both on the gamma-corrected values and on the first pixel values. A pixel-value generating portion includes an extracting portion and a determining portion. The extracting portion extracts at least one of the table values corresponding to a pixel value of a subject pixel. The determining portion determines a pixel value of an output image based on the at least one of the table values extracted by the extracting portion. The predetermined reflectance component is the reflectance component calculated by the reflectance-component calculating portion when the pixel value of the subject pixel is substantially identical with the average luminance of the peripheral pixels.
