Document Type and Number:
Japanese Patent JP7117626
Kind Code:
B2
Abstract:
A video display apparatus (102) includes: a tone mapping processor (123) 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 (124) that displays the video that has undergone the tone mapping process. The tone mapping processor (123) 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.
