1. A color correction system for improving a performance of a light source display having a plurality of distinct light sources of a plurality of different colors, the color correction system comprising:
a spectral analysis system including a computing device, the spectral analysis system being configured to
receive image data obtained from light emitted by the light source display, the image data including performance information relating to a visual performance of the plurality of distinct light sources of the plurality of different colors of the light source display,
generate comparison information by comparing the performance information of the distinct light sources of the plurality of different colors of the light source display with a reference, and
determine color correction data taking into account the comparison information; and
a light source controller configured to
receive the color correction data, and
adjust the performance of the light source display by outputting a light source control signal to the light source display, the light source control signal including operating parameters for the plurality of distinct light sources of the plurality of different colors of the light source display, said operating parameters including one or more color correction factors taking into account the color correction data determined by the spectral analysis system,
wherein the color correction data is determined by the spectral analysis system further by taking into account a color sensitivity of a camera that captures an image of the light source display.
