DISPLAY DEVICE, VIDEO SIGNAL PROCESSING METHOD, AND PROGRAM

摘要

A display device includes a display unit formed by pixels arranged in a matrix. Each of the pixels has a light emitting element which emits light in accordance with a current amount and a pixel circuit which controls the current to be applied to the light emitting element according to a voltage signal. The display device includes: an average luminance calculation unit (200) which calculates an average of luminance of inputted video signals during a predetermined period; and a light emission time setting unit (202) which sets a real duty for defining the light emission time for causing the light emission elements to emit light for each frame in accordance with the average luminance calculated by the average luminance calculation unit (200). The light emission time setting unit (202) sets the real duty so that the light emission amount defined by a preset reference duty and a maximum luminance of the video signal is identical to the light emission amount defined by the set real duty and the average luminance.
