<p>A video display device comprises: panels (16a, 16b, 16c) including a plurality of pixels that change light transmittances according to video levels; a detector (12) for detecting, from video signals indicating the video levels of respective pixels, the video levels of the respective pixels included in one frame of each of the panels (16a, 16b, 16c); and a processor (18) for, when a value corresponding to brightness based on the video levels of one frame detected by the detector (12) is greater than a predetermined threshold value, determining the offset amount of a black level and notifying a black level adjuster (13) of the offset amount of the black level for each color. By shifting a video level of black reproduction to the white reproduction side by a predetermined amount, the light transmittances of the pixels are adjusted so that the whole image becomes brighter.</p> |
