Claim 4:
5. The device according to claim 1, wherein at least one spectral band of interest is defined, the first spectral band is a spectral band of interest and the second spectral band is a reference spectral band, each spectral band of interest being centered on a wavelength of interest, each reference spectral band being selected from the group consisting of:
a spectral band centered on a different wavelength from the or each wavelength of interest,
a spectral band disjoint from the or each spectral band of interest, and
a spectral band in which at least one spectral band of interest is strictly included,
the first pixel comprising a filter suitable for transmitting only the first spectral band, the second pixel comprising a filter suitable for transmitting only the second spectral band.
