Abstract
A video reproduction device (100) reproduces expanded video data (DV1) whose brightness dynamic range is wider than a standard video. The video reproduction device (100) includes a brightness information adjustment unit (150). The brightness information adjustment unit (150) changes first output brightness levels of the expanded video data (DV1) to second output brightness levels. When the expanded video data (DV1) is reproduced at a second reproduction speed faster than a first reproduction speed which is a normal speed, the brightness information adjustment unit (150) reduces the first output brightness levels to the second output brightness levels.
