Document Type and Number:
Japanese Patent JP7108880
Kind Code:
B2
Abstract:
A video display apparatus (102B) includes: a tone mapping processor (134) that converts, by using dynamic metadata indicating a maximum luminance of a video in each of a plurality of time intervals included in a predetermined period, a luminance of the video in each time interval based on conversion characteristics according to the maximum luminance of the video in the time interval; and a display (135). The tone mapping processor (134) switches between: a first operation of performing the tone mapping process by using first dynamic metadata that indicates the maximum luminance that is constant over the plurality of time intervals, the first dynamic metadata being generated by using static metadata that indicates a maximum luminance of the video in the predetermined period; 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.
