摘要： 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.

摘要： A video display system 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-depend 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-depend change in the maximum luminance of the video. When the tone mapping process used is switched from the second tone mapping process to the first tone mapping process, the conversion characteristics used is changed gradually or stepwise from the constant conversion characteristics to dynamically changing conversion characteristics over a plurality of frames.
