Classification: CPC H  G | IPC G  H

Claim 3:
4. The method as claimed in claim 3 wherein the spectrum of the flash illumination is represented by a flash illumination vector (E(λ)) of length m, where m represents a number of wavelength points defined by the spectrum; wherein a sensitivity of the multispectral sensor at the wavelength points for each wavelength channel is defined by a n×m sensitivity matrix (S(λ)); and wherein compensating the scene flash spectrum using the spectrum of the flash illumination comprises multiplying the scene flash spectrum vector (DTF) by a matrix (MTF) defined by a combination of the sensitivity matrix and the flash illumination vector to obtain a colour-compensated scene flash spectrum vector (RT(λ)) representing the colour-compensated scene flash spectrum.
