REPRODUCTION DEVICE, REPRODUCTION METHOD, AND RECORDING MEDIUM

摘要

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 a Tone_map stream including 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 and 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 of the HDR graphics. The present technology is applicable to a recording medium recording graphics.

主权项

1. A reproduction device comprising:
a reading unit configured to read a Tone_map stream and a graphics stream from a recording medium that records the Tone_map stream including HDR information indicating a luminance feature of extended graphics which are graphics with a second luminance range different from and broader than a first luminance range and luminance conversion definition information used when luminance conversion from the extended graphics to standard graphics which are graphics with the first luminance range is performed, and the graphics stream of the extended graphics; a conversion unit configured to convert the extended graphics into the standard graphics based on the luminance conversion definition information of the extended graphics included in the Tone_map stream; and an output unit configured to output the extended graphics and the HDR information of the extended graphics included in the Tone_map stream to a display device which is capable of displaying the extended graphics and output the standard graphics converted by the conversion unit to a display device which is not capable of displaying the extended graphics.
