The present invention provides a simple, low-cost color classification apparatus having a high resistance to mechanical vibrations and capable of properly performing color classification even if a light source is not specified and its spectrum changes. A color classification apparatus of the present invention is further including an image pickup means for picking up a spectrum of light reflected by a target object, a plurality of bandpass filters having different bands and arranged between the target object and the image pickup means, and a classifying means for calculating a classification spectrum for classification using a statistic technique from a spectrum of light reflected by the target object and picked up by the image pickup means, and classifying the target object using the classification spectrum.
