Abstract: A display device according to an embodiment may include a controller and a display unit. The controller may perform tone mapping for adjusting luminance of input image data, and the display unit may display an image according to output image data whose luminance is adjusted by the tone mapping. The controller may generate a base mapping curve for an entire region from the input image data, extract information for each local region of the entire region, and generate a local mapping curve reflecting the information for each local region with respect to each local region to perform tone mapping.
