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.
