Camera characterization for color research

Kobus Barnard and Brian Funt, "Camera characterization for color research," Color Research and Application, Vol. 27, No. 3, pp. 153-164, 2002. [ Full text (pdf) ]


We introduce a new method for estimating camera sensitivity functions from spectral power input and camera response data. We also show how the procedure can be extended to deal with camera non-linearities. Linearization is an important part of camera characterization and we argue that it is best to jointly fit the linearization and the sensor response functions. We compare our method with a number of others, both on synthetic data and for the characterization of a real camera. All data used in this study is available on-line at http://www.cs.sfu.ca/~colour/data.

Keywords: color, colour, color constancy, camera calibration, camera spectral characterization
