WebThe camera predictions are made by computing the resulting RGB values for the given camera’s sensitivity functions and then mapping them to the corresponding XYZ values based on a best linear fit of the camera sensitivity function to the CIE 1931 2°-observer x ¯, y ¯, z ¯ color matching functions. They measured the sensor sensitivity ... WebThe three curves are called functions of color matching or correspondence CIE (CIE color-matching functions) and define a specific standard observer, called the CIE 1931 …
WebThe CIE originally defined the standard observer in 1931 using a 2 field of view, hence the name 2 Standard Observer.
