Color sensing device |
摘要 |
A color sensing device comprising four photo-electric transducers formed on a semiconductor substrate, an interference filter provided on the light receiving face of each transducer, a colored filter for selecting a specified transmission band of the interference filter, and three electrodes for delivering electric signals from the transducers individually, one of the electrodes being provided for two of the transducers in common. The transducers each have the area of its light receiving face so determined as to exhibit spectral sensitivity characteristics matching the color matching function of the CIE (Commission Internationale de l'Eclairage) XYZ colorimetric system.
