The image encoder is configured to output data specifying the color mapping (Fi(MP_DH)). Further, the image encoder includes an automatic grading unit configured to derive a second low dynamic range image (GT_IDR) by applying an automatic color mapping algorithm to one of the high dynamic range input image (M_HDR) and the low dynamic range image (Im_LDR)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"HDR image encoding and decoding methods and devices","description":"An image encoder includes an input for a high dynamic range input image (M_HDR); an image grading unit arranged to allow a human color grader to specify a color mapping from a representation (HDR_REP)","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9699482","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.
