Abstract:
1. 1 A display device comprising: a brightness histogram information producing unit that produces brightness histogram information on the basis of an image signal; a highest class determining unit that determines a highest class, which is a class with a highest brightness, on the basis of the brightness histogram information; and a white peak value determining unit that determines a white peak value of a current frame by adding a predetermined value to a white peak value of a previous frame when a highest class difference absolute value, which is an absolute value of a difference value between a highest class of the previous frame and a highest class of the current frame, is less than a threshold value and that determines a white peak value of the current frame by performing a predetermined operation regardless of a white peak value of the previous frame when the highest class difference absolute value is equal to or larger than the threshold value.
