Multimedia systems and equipment - Colour measurement and management - Part 2-2: Colour management - Extended RGB colour space - scRGB

this standard is applicable to the encoding, editing and communication of relative scene radiance, wide dynamic range, extended colour gamut, and extended bit precision RGB colours as a colour space used in computer systems and similar applications by defining encoding transformations.

La CEI 61966-2-2:2003 s'applique au codage, à l'édition et à la communication des couleurs RVB de radiance de scènes relatives, large plage dynamique, gamme de couleurs étendue et précision en bits étendue, en tant qu'espace colorimétrique utilisé dans les systèmes informatiques et les applications similaires par définition des transformations de codage. Les valeurs des primaires et du point blanc de l'espace colorimétrique définies dans la présente norme sont identiques aux chromaticités CIE pour les primaires de référence UIT-R BT.709-5 et pour l'illuminant normalisé CIE D65 comme son point blanc. L'espace colorimétrique scRVB est une extension de sRVB et il est considéré comme compatible avec sRVB. La présente version bilingue (2013-02) correspond à la version anglaise monolingue publiée en 2003-01.

Overview

EN 61966-2-2:2003 (identical to IEC 61966-2-2:2003) specifies the scRGB extended RGB colour space and the encoding transformations needed to represent relative scene radiance, wide dynamic range, extended colour gamut, and extended bit precision RGB data in computer systems and similar applications. Published by CLC, this standard focuses on colour measurement and colour management for multimedia systems and equipment and defines how scRGB should be encoded, edited and communicated to support high-dynamic-range and high-precision workflows.

Key topics and requirements

• Scope of application: Encoding, editing and communication of relative scene radiance and extended-range RGB colours in computer systems.
• Encoding transformations: Specifies the transformations required to map scene-referred radiance and extended RGB data into the scRGB encoding for interoperable exchange (the standard defines how to encode/decode scRGB).
• Wide dynamic range support: Addresses representation of luminance values beyond conventional low dynamic range RGB spaces to enable HDR content handling.
• Extended gamut and precision: Enables representation of wider colour gamuts and higher bit depths (extended bit precision) for accurate colour editing and processing.
• Interoperability and colour management: Provides a standardized foundation for consistent colour handling across software, displays and imaging pipelines that adopt scRGB.

Applications

• Image and video editing software that requires HDR and high-precision colour processing.
• Graphics and rendering pipelines in computer graphics, visualization and CAD that operate on scene-referred radiance.
• Display manufacturers and video-system vendors implementing wide-gamut, high-dynamic-range workflows.
• Colour management systems and colour scientists integrating scRGB into profiles and conversion chains.
• Professional photography, film post-production and printing workflows that need extended gamut and precision for intermediate processing stages.

Who should use this standard

• Software developers building colour-managed imaging and rendering applications.
• Hardware vendors (displays, GPUs, capture devices) implementing scRGB-compatible pipelines.
• Colour management engineers, imaging professionals and system integrators seeking standardized HDR and wide-gamut colour handling.
• Standards bodies and test labs referencing a harmonized approach to scRGB encoding transformations.

Related standards

• EN/IEC 61966-2-1 (sRGB) - standard RGB colour space for conventional displays and web content.
• Other colour measurement and management documents (CIE and ICC specifications) used together with scRGB in colour-managed systems.
