Abstract
An image forming apparatus includes a control section extracting a color composition of each color ranging from a first to an ncolor from input image data, on the color composition of an mcolor, the m being 1 to n−1, performing a first and a second gamma corrections correcting a gradation of the color composition respectively based on a gamma curve for the mcolor to obtain a first corrected gradation value, and based on a gamma curve for an (m+1)color to obtain a second corrected gradation value, and interpolating the first and the second corrected gradation values to determine an output value for the color composition, on the color composition of the ncolor, correcting a gradation of the color composition based on a gamma curve for the ncolor to obtain an output value for the color composition.
