The reproduction device reads a Tone_map stream and a graphics stream of an extended graphics from a recording device, wherein the recording device records the Tone_map stream including HDR information indicating a luminance feature of the extended graphics which are first graphics with a first luminance range different from and broader than a second luminance range, and a luminance conversion definition information used in luminance conversion from the extended graphics to standard graphics. The standard graphics are graphics with the second luminance range. The reproduction device converts the extended graphics into the standard graphics based on the luminance conversion definition information of the extended graphics included in the Tone map stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reproduction device, reproduction method, and recording medium that display graphics based on tone mapping","description":"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 brightne","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832440","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
