Claim 18:
19. 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 including multiple camera system having multiple cameras recording images from said display, said multiple cameras comprising each a shutter with 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 at least 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 the shutter opening time of one of said multiple cameras;
calculating at least a second calibration matrix based on the measured colors and on at least second set of target colors, for during the shutter opening time of another of said multiple cameras;
defining a matrix factor, being selectively chosen in relation to the shutter opening time of each of said multiple cameras, as a number;
calculating a final calibration matrix, defined by said first and at least second calibration matrix, each being weighed based on said matrix factor.
