Result data indicating distribution of a biological metabolite concentration of a subject are generated by using biophotonic measurement data obtained with a biophotonic measurement device, whether the result data satisfy an arbitrary extraction condition concerning biophotonic measurement data set beforehand or not is judged, the result data are distinguishably displayed according to the results of the judgment, and thereby failure of extraction of measurement data of characteristic channels from result data obtained from as many as several tens of channels is prevented without depending on subjectivity of measurement operator.
