What is this BS EN 61966-2-2 - Colour measurement and management about?
BS EN 61966-2-2 discusses multimedia systems and equipment and colour measurement and management with a focus on colour management and extended RGB colour space and scRGB. BS EN 61966-2-2 is the second part of the multi-series on BS EN 61966 multimedia systems and equipment that 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.
Primaries and white point values of the colour space defined in BS EN 61966-2-2 are identical to CIE chromaticities for ITU-R BT.709-5 reference primaries and CIE standard illuminant D65 as its white point. The scRGB colour space is an extension of sRGB and it is considered compatible with sRGB. Additional transformations, such as white point adaptation methods, are beyond the scope of BS EN 61966-2-2. The appropriate CIE recommendations should be referred to for guidelines in this area.
Note: BS EN 61966-2-2 does not specify limiting values for various parameters.
Who is BS EN 61966-2-2 - Colour measurement and management for?
BS EN 61966-2-2 on colour measurement and management is useful for:
- Television manufacturers
- HDR technology developers
- Research and development personnel
- Design engineers
Why should you use BS EN 61966-2-2 - Colour measurement and management?
BS EN 61966-2-2 are a series of methods and parameters for colour measurements and management for use in multimedia systems and equipment applicable to the assessment of colour reproduction.
The method of digitization in BS EN 61966-2-2 is designed to provide high bit precision, large colour gamut and extended dynamic range that is linear with respect to scene radiance. Based on IEC 61966-2-1 (sRGB), this colour space is well suited to meet the needs of the multimedia, gaming and computer graphics applications.
BS EN 61966-2-2 provides a robust solution to these needs. The white point and colour primaries of the scRGB solution are directly inherited from the IEC 61966-2-1 (sRGB) standard. The encoding transformations provide all of the necessary information to encode an image.
