The invention is directed to generic spectral modeling techniques applicable to a variety of imaging devices. A generic spectral model may include a general channel model capable of modeling spectral characteristics of imaging devices and a look-up table (LUT) capable of compensating for cross-channel interaction and possibly other characteristics that are difficult to model, such as non-linear characteristics of imaging devices. In this way, the generic spectral model includes aspects of both a conventional physical model and a conventional brute force model. Digital values, i.e., pixel counts, of each channel of an imaging device are adjusted by the LUT of the generic spectral model to include cross-channel interaction. The channel model then accurately predicts spectral emissions for each channel of the imaging device based on the adjusted digital values. The generic spectral model converts the predicted spectral emissions to a device-independent color space. |
