Abstract
An image processing apparatus including a selection section which, by selecting an electricity consumption minimum value where electricity consumption of a display section, which performs a display based on a value out of a plurality of values which are present within a predetermined distance from a pixel value of an image in a uniform color space, is a minimum as a pixel value of the image after color conversion, generates an image after the color conversion.
