Video display apparatus and video display method for luminance conversion
A video display apparatus includes: a video receiver that acquires video data including a main video; a generator that generates first characteristics information that indicates first dynamic luminance characteristics by using the video data when a luminance dynamic range format of the main video indicated by the video data is different from a display format that indicates a luminance dynamic range format displayable by the video display apparatus, the first dynamic luminance characteristics being dynamic luminance characteristics indicating a time-dependent change in luminance characteristics of the main video and correspond to the display format; a tone mapping processor that performs a tone mapping process of converting a luminance of the main video based on conversion characteristics according to the first dynamic luminance characteristics indicated by the first characteristics information generated by the generator; and a display that displays the main video that has undergone the tone mapping process.
