Claim One:
1. A display device comprising: an average picture level (APL) calculator configured to calculate an APL of an input image and output the APL of the input image and an APL curve data; a luminance adjuster including at least two luminance adjusting units, which are enabled in response to a user input through a user interface, the luminance adjuster adjusting the APL curve data; a data modulator configured to modulate data of the input image using a luminance defined in the APL curve data adjusted by the luminance adjuster; and a display panel driving circuit configured to write data from the data modulator on a display panel and reproduce the input image on the display panel, wherein the luminance adjuster includes: a first luminance adjusting unit configured to generate a first weight value, which is set based on an input luminance input through a user interface; a first multiplier configured to multiply the APL curve data by the first weight value; a second luminance adjusting unit configured to decide a motion of the input image and generate a second weight value, which reduces a maximum luminance of the display image as a motion of the input image increases; and a second multiplier configured to multiply the APL curve data received from the first multiplier by the second weight value.
