Abstract
The present invention relates to a categorical color perception system which automatically judges a categorical color and aims to judge a categorical color name correctly under various ambient lights. Test color measured at an experiment is inputted to an input layer portion corresponding to test color components 101, illumination light components at the experiment are inputted to an input layer portion corresponding to illumination light components 102, and connection weights are obtained by learning with backpropagation method so as to output a categorical color judged by an examinee. Although a structure between the input layer portion corresponding to test color components 101 and the input-side hidden layer portion corresponding to test color components 103 and a structure between the input layer portion corresponding to illumination light components 102 and the input-side hidden layer portion corresponding to illumination light components 104 are independent, weights of structurally corresponding connections are made the same.
