Abstract: A method begins by generating a received light spectrum at time T1 for a scene using a spectral imager that includes a plurality of spectral sensors, where a spectral sensor includes a spectral filter overlaying one or more first optical sensors and the sensing range for the plurality of spectral sensors together include a spectrum of wavelength and outputting information representative of a spectral image for the scene at T1 to a processing module. The method continues by using an image sensor to image the scene at time T2, where the image sensor includes a plurality of second optical sensors, and outputting information representative of an image of the scene at T2 to the processing module where the image of the scene has a spatial resolution that is higher than the spatial resolution of the spectral image. The method continues by producing a combined spectral image based on the information representative of a spectral image for the scene at T1 and the information representative of the image at T2 and correcting, based on the combined spectral image, an illuminant for one or more spatial areas of the scene to produce a corrected spectral image.
