Abstract:
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.
