Abstract: A video display system includes: a tone mapping processor; a display; and a metadata processor that generates first dynamic metadata that indicates a maximum luminance that is constant over a plurality of time intervals by using static metadata. The video display system switches between: a first operation of (i) generating the first dynamic metadata by using the static metadata, performed by the metadata processor and (ii) performing the tone mapping process by using the first dynamic metadata, performed by the tone mapping processor; and a second operation of performing the tone mapping process by using second dynamic metadata in which the maximum luminance varies over the plurality of time intervals, performed by the tone mapping processor.

Abstract: A video display device includes: a video receiver that obtains 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.

Abstract: A video display apparatus includes: a tone mapping processor that performs a tone mapping process of converting a luminance of a video by using conversion characteristics according to a maximum luminance of the video; and a display that displays the video that has undergone the tone mapping process. The tone mapping processor switches between a first tone mapping process of dynamically changing the conversion characteristics according to a time-dependent change in the maximum luminance of the video and a second tone mapping process that is performed using constant conversion characteristics irrespective of the time-dependent change in the maximum luminance of the video.
