Abstract
According to one embodiment, there is provided an image processing apparatus including: first circuitry and second circuitry. The first circuitry sets for first color information in a first color gamut a correction quantity of a brightness defined depending on a lightness and a chroma of the first color information on a basis of a difference between a target brightness and the brightness of the first color information. The second circuitry corrects at least one of the lightness and the chroma of the first color information such that the brightness of the first color information is corrected by the correction quantity to obtain corrected color information in the first color gamut.
