1. A color classifying apparatus comprising:

  • imaging means for imaging reflected light from an object;

    optical means for forcing said reflected light from the object to form multispectral images each having a different band on said imaging means; and

    classifying means for computing a classification spectrum for classification using a statistical approach based on multispectral image data relating to the multispectral images formed by said imaging means, and for classifying said object into a plurality of classes using the computed classification spectrum, wherein said classifying means includes;

    (i) a plurality of classification judging sections that make a classification judgment on said plurality of classes using a plurality of different classification judgment methods; and

    (ii) a judgment result judging section that comprehensively judges the classification judgments of one or more of said plurality of classification judging sections, and wherein said judgment result judging section of said classifying means judges the classification judgment of a first one of said plurality of classification judging sections and then judges whether to cause a second one of said plurality of classification judging sections to make a classification judgment based on a judgment result of the classification judgment of the first one of said classification judging sections.
