Video display apparatus and video display method

A video display apparatus, comprising:

• 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, wherein,
• when the video does not contain graphics, the tone mapping processor performs, on all pixels of an entire screen, a first tone mapping process of dynamically changing the conversion characteristics according to a time-dependent change in the maximum luminance of the video,
• when the video contains graphics, the tone mapping processor performs, on all the pixels of the entire screen, a second tone mapping process using constant conversion characteristics irrespective of the change in the maximum luminance of the video, and
• the tone mapping processor determines which of the first tone mapping process and the second tone mapping process is to be performed on all the pixels of the entire screen according to a first flag that indicates, for each frame unit, which of the first tone mapping process and the second tone mapping process is to be performed.
