Abstract
A video display device includes: a video receiver that receives video data including a video and dynamic luminance characteristics indicating a time-dependent change in luminance characteristics of the video; a tone mapping processor that, in the case where a luminance region having a luminance less than or equal to a first luminance is defined as a low luminance region, and a luminance region having a luminance exceeding the first luminance is defined as a high luminance region, (i) performs first tone mapping using first conversion characteristics when first luminance characteristics exceed a predetermined threshold value, and (ii) performs second tone mapping using second conversion characteristics when the first luminance characteristics are less than or equal to the predetermined threshold value.
