Popis: | The transition to High Dynamic Range (HDR) requires new standards for video. Existing standards for SDR have tacitly assumed the CRT's native response characteristics for the Electro-Optical Transfer Function or EOTF, often referred to as ‘gamma’. Since the EOTF was universal and fixed by the physics of the CRT, SDR standards have been typically expressed in terms of the complementary Opto-Electrical Transfer Function or OETF. Unfortunately, viewing the video pipeline solely in terms of the OETF (e.g., BT.709) and EOTF (e.g., BT.1886) is somewhat ambiguous. The resolution of this ambiguity requires the inclusion of the Opto-Optical Transfer Function or OOTF. This paper explains this ambiguity and why it is important for HDR. It closes with a description of an OOTF for HDR that is compatible with the OOTF of existing SDR standards. |
