Color Camera Characterization with an Application to Detection under Daylight

A technique for measuring the spectral sensitivity curves of color cameras is described. Details on the difficulties that might be encountered in such measurements are discussed. These are mostly related to the non-ideal behavior of cameras, and the properties of the quasi-monochromatic light that must be presented to the camera. The usefulness of these curves is illustrated on a specific example: that of detecting colored objects of known spectral reflectances under daylight illumination conditions.
