Abstract
A sensor system includes an array of optical sensors on an integrated circuit and a plurality of sets of optical filters atop at least a portion of the array. Each set of optical filters is associated with a set of optical sensors of the array, with a set of optical filters including a plurality of optical filters, with each optical filter being configured to pass light in a different wavelength range. A first interface is configured to interface with the optical sensors and first processing circuitry that is configured to execute operational instructions for receiving an output signal representative of received light from the optical sensors and determining a spectral response for each set of optical sensors. A second interface is configured to interface with the first processing circuitry with second processing circuitry that is configured for determining, based on the spectral response for each set of optical sensors, an illuminant spectrum for each spectral response and then substantially remove the illuminant spectrum from the spectral response.
