Abstract
A display device is provided, including circuitry configured to calculate a table representing a relationship between an average brightness and a gain of a video signal; revise the table in order to reduce a change amount of a gain of each frame in the table; calculate an average brightness of a video signal input for each frame; calculate a gain of a video signal from the table based on the calculated average brightness; adjust a video signal using the calculated gain; and a display panel that includes a plurality of pixels that emit light in response to a video signal and displays a video based on the adjusted video signal. A brightness adjustment device, a backlight device, and a method of adjusting brightness, each including the circuitry, are also provided.
