Systems and methods for compensating for temperature induced spectral emission variations in LED based color parameter measuring devices

A color parameter value determination system, comprising:

• a plurality of illuminants;
• at least one photodetector that detects light originating from the plurality of illuminants and reflected by a target;
• and
• a controller that:
• processes the plurality of illuminant sensor outputs obtained from at least one photodetector at an operating temperature, each illuminant sensor output indicating a color value obtained from a target;
• obtains a measurement of the operating temperature;
• retrieves model information from the reference database based on the operating temperature and the sensor outputs, the reference database containing different model information for different temperatures;
• determines a model for the operating temperature and the sensor outputs based on the retrieved model information;
• and
• determines a color parameter value based on the determined model.
