Abstract
An integrated radiation sensor for color matching functions comprises a plurality of color matching channels, each color matching channel comprising a radiation sensing element and an associated optical filter defining a spectral sensitivity profile corresponding to a color matching function. The sensors comprise a plurality of compensation channels, each compensation channel comprising a radiation sensing element and an associated optical filter defining a spectral sensitivity profile for use in compensating a color sensed by the color matching channels. The spectral sensitivity profile of each compensation channel substantially corresponds to a mean of an upper deviation spectra and a lower deviation spectra, wherein the upper deviation spectra corresponds to a spectral sensitivity profile of a typical color matching channel increased by a fixed deviation in wavelength and the lower deviation spectra corresponds to the spectral sensitivity profile of the typical color matching channel decreased by the fixed deviation in wavelength.
