PROBLEM TO BE SOLVED: To determine types and discrimination conditions of feature quantities used in discrimination processing of discriminating whether subject data are data of specific content or not, in dependence on a desired balance between discrimination precision and a computational complexity burden in the discrimination processing. SOLUTION: A discriminator creation part 16 of a device 10 for determining types and discrimination conditions of feature quantities creates discriminators corresponding to a plurality of feature quantities usable in discrimination processing, according to a sample data group. For each created discriminator, a discrimination precision specification part 18 and a computational complexity specification part 20 specify a discrimination precision index value and a computational complexity index value respectively. A discriminator selection part 22 derives comprehensive evaluation values from the index values to select desirable discriminators. According to the selected discriminators, a discrimination condition determination part 24 determines types and discrimination conditions of feature quantities used in discrimination processing.
