Abstract
The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable content having a wide dynamic range of brightness to be displayed with an appropriate brightness. A recording medium, on which the reproduction device of one aspect of the present technology performs reproduction, records coded data of an extended video that is a video having a second brightness range that is wider than a first brightness range, brightness characteristic information that represents a brightness characteristic of the extended video, and brightness conversion definition information used when performing a brightness conversion of the extended video to a standard video that is a video having the first brightness range. The reproduction device decodes the coded data and converts the extended video obtained by decoding the coded data to the standard video on the basis of the brightness conversion definition information.
