Abstract
A display device includes: a light emission amount detecting section which inputs video signals having linear property and detects an amount of light emission from the video signals; a light emitting time calculating section which calculates light emitting time of the light emitting elements based on the amount of light emission detected by the light emission amount detecting section; a light emitting time recording section which records the calculated light emitting time; a luminance acquiring section which, acquires luminance information of the light emitting elements using the light emitting time recorded in the light emitting time recording section; a coefficient calculating section which calculates coefficients by which the video signals are multiplied based on the luminance information acquired by the luminance acquiring section; and a coefficient multiplying section which multiplies the video signals by the coefficients calculated by the coefficient calculating section.
