Abstract

A wrinkle detection method comprises the steps of obtaining face data of a subject; setting one or more analytical regions on the obtained face data; producing plural pieces of wrinkle component extracted data by extracting wrinkle components extending in one direction or in plural directions at different angles from each other in an angle range in which wrinkles tend to extend and which is set in advance for the set one or more analytical regions; producing plural pieces of wrinkle component emphasized data corresponding to the pieces of wrinkle component extracted data, respectively, by emphasizing the wrinkle components; producing composite data by combining the pieces of wrinkle component emphasized data; and detecting a wrinkle component having an intensity equal to or greater than a predetermined threshold value from the composite data as a wrinkle of the subject.
