Abstract: We present a new approach to 2D-imaging colorimetry yielding significantly improved measurement accuracy for virtually all sample sources. This approach combines two important innovations. The first is to use a camera equipped with six optical filters instead of the often used three or four channels. This clearly improves the fitting to the three human eye¡¯s color matching functions. However, simply extending the number of filters, i.e. the number of data acquisition channels is only one step to improve the measurement accuracy. Here it is presented how the performance of a six filter?imaging camera can be further improved by the usage of an advanced matrix optimization based on a set of training sources. This combination guarantees a significantly better overall performance that is especially advantageous when it comes to measuring typical LEDs.
