Abstract

A display device includes an image processing unit that performs image processing on image data input from the outside, and performs display output corresponding to the image data on which image processing is performed by the image processing unit. The image processing unit includes a first processing circuit that simply replaces colors of an image to limit the number of colors used for the image to a predetermined number equal to or smaller than 16, a second processing circuit that performs image processing including arithmetic processing for improving luminance of a plurality of pixels constituting the image displayed on the display device corresponding to the image data; and a switching unit that causes the second processing circuit to perform image processing, and causes the first processing circuit to perform image processing when performing the image processing while saving more power than the second processing circuit.
