CIE XYZ sensor
This sensor uses the CIE 1931 2° Standard Observer response functions, and generates three channels X, Y and Z. It is used for most image renderings, as well as for photometry applications (as the Y channel corresponds to the standard luminance).
- Generates a single Y luminous channel instead of XYZ color space
