Image processing apparatus having a gradation conversion unit that executes gradation conversion processing, and image processing method for the same

摘要

An image processing apparatus includes: a gradation conversion unit that executes gradation conversion processing based upon gradation conversion features assuming a slope that changes at a predetermined brightness level, on a component representing a brightness of an image in a color space expressed with the component representing the brightness and a component representing a color depth; and a modulation unit that executes modulation processing on the component representing the color depth by multiplying the component representing the color depth by modulation features, wherein: the modulation features are set so as to assume values equal to or less than 1 over at least part of a brightness range above the predetermined brightness level.
