Abstract
A display device that can adjust brightness of each of a plurality of regions of an image by performing local dimming executes local dimming in a case of displaying a multi-color image (color image), and does not execute local dimming in a case of displaying a grayscale image. Moreover, in a case of displaying a mixed image of a multi-color image and a grayscale image, the display device does not execute local dimming in regions including a grayscale image among a plurality of regions of an image. Displaying a multi-color image at high contrast and displaying a grayscale image at high tone reproduction are both achieved.
