CONTENT MAPPING USING EXTENDED COLOR RANGE |
摘要 |
In high-dynamic range (HDR) coding, content mapping translates an HDR signal to a signal of lower dynamic range. Coding and prediction in layered coding of HDR signals is improved if content mapping utilizes signal color ranges beyond those defined by a traditional electro-optical transfer function (EOTF) or its inverse (IEOTF or OETF). Extended EOTF and IEOTF functions are derived based on their mirror points. Examples of extended EOTFs are given for ITU BT. 1886 and SMPTE ST 2084. |
