REPRODUCTION DEVICE, REPRODUCTION METHOD, AND RECORDING MEDIUM
Abstract:
The present technology relates to a reproduction device, a reproduction method, and a recording medium capable of displaying graphics with a broader dynamic range of luminance and appropriate brightness.An optical disc records tone_mapping_info including HDR information indicating a luminance feature of HDR graphics which are graphics with a second luminance range different from and broader than a first luminance range, tone_mapping_info which is tone mapping definition information used when luminance conversion from the HDR graphics to STD graphics which are graphics with the first luminance range is performed, and a graphics stream including data of the HDR graphics. The present technology is applicable to a recording medium recording graphics.
