Abstract:
In a video display device of the present invention, a main control unit is equipped with a user interface for varying correction values set to a range correction unit and controls a range correction unit by acquiring the corresponding correction values from a storage unit in accordance with correction level information input by the user interface. The storage unit stores range correction values for the video display unit in correspondence with each piece of the correction level information input by the user interface. Thus, it is possible to correct luminance ranges to suit the user's preference without causing a large luminance reduction.
