Abstract
An image processing apparatus for performing image processes corresponding to input signals of multiple types, includes a luminance correcting unit that performs correction process on an input signal so as to correct for display luminance, a luminance decreasing unit that multiplies the input signal with a gain smaller than '1', and a gamma correcting unit that performs gamma correction with a gamma value smaller than '1' on the input signal. The luminance decreasing unit and the gamma correcting unit are combined together to execute a first correction process that decreases a luminance of a highlight portion of an image while maintaining or increasing the luminance of a halftoned portion of the image, and the luminance decreasing unit executes a second correction process that decreases the luminance for substantially overall tone levels of the image.
