Abstract
A color sensor comprising a plurality of detecting units. One of the detecting units may inspect the color of an object to be examined, and the other may inspect the color of the reference object simultaneously and independently. The reflected light of the object to be examined is corrected by the reflected light of the reference object. The lights reflected from the object to be examined and the reference object are derived from the same light source.
