Methods, apparatus, and systems for mapping extended tones of wide dynamic range (HDR) for HDR HDR

摘要

Methods, apparatus,And systems for mapping extended tones of wide dynamic range (HDR) HDR HDR to aspects of these principles relate to methods and apparatus for mapping of the tones of aImage of a wide dynamic range.The apparatus includes a processor for executing the following steps.Moreover, the method comprises the following steps: obtaining a luminance component of the image of wide dynamic range; determining a mapping of the tone curve of the HDR to a trackHDR less; determining a color image compressed by applying the mapping of the tone curve of the HDR HDR to a range lower than the luminance component of the image of a wide range dinu00e2Mica; and the mapping of the tone curve of band to band HDR HDR comprises a first part for levels of midtones, and dark, and a second part for enhancements.
