Claim 17:
18. A method for color calibration over time, the method comprising:
providing the arrangement of claim 11, wherein the at least one light source display includes a plurality of light-emitting elements (LEEs), and said at least one camera comprising a shutter having a shutter opening time;
performing a color measurement of the plurality of LEEs of said display;
determining color space values for the color measurement of said plurality of LEEs;
defining for said plurality of LEEs a first set of target colors in color space values;
defining for said plurality of LEEs a second set of target colors in color space values;
calculating a first calibration matrix based on the measured colors and on the first set of target colors, for during said shutter opening time;
calculating a second calibration matrix based on the measured colors and on the second set of target colors, for out of said shutter opening time;
defining a matrix factor, being selectively chosen in relation to said shutter opening time, as a number;
calculating a final calibration matrix, defined by said first and second calibration matrix, each being weighed based on said matrix factor.
