Abstract
A method comprising: applying a respective value of a first plurality of values of a first control parameter to each light source of a projector system, wherein each of the first plurality of values of the first control parameter determines an output luminance of a corresponding light source; measuring a first luminance and first colour space coordinates of a light pattern displayed based on the first plurality of values; converting the first luminance and first colour space coordinates to corresponding tristimulus values; calculating therefrom a respective colour luminance value corresponding to each light source; calculating a linear relationship between the first control parameter and each colour luminance value; determining a second plurality of values of the first control parameter based on the linear relationships and a target colour luminance value for each light source; and controlling the plurality of light sources using the second plurality of values.
