Abstract
A display device includes a set period setting unit for setting, as a set time, a time for which a set period elapses from a time at which a first area included in an input image is detected as a still area, and a gain generator for gradually decreasing an initial level of a gain value down to a saturation level having a lowest value of the gain value from the set time. The set period setting unit differently sets the saturation level of the gain value and a final level of the gain value, corresponding to grayscale values of the first area and a load value of the input image. The load value is an average value of grayscale values of an entirety of an area of the input image.
