摘要
Cameras for capturing an image of an object include a CCD, an optical filter for removing energy of a portion of the spectrum wavelengths, and a ND filter for variable light attenuation. Methods for generating 4-band image data involve obtaining four spectral channels of data using a single CCD and generating 4-band image data. Methods for generating a 4×4 (or a 3×3) color correction matrix involve obtaining four (or three) spectral channels of data with a single CCD and generating the 4×4 (or 3×3) color correction matrix based on these four (or three) spectral channels of data.
