WRINKLE STATE-ANALYZING METHOD, AND WRINKLE STATE-ANALYSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a technology for precisely quantifying a wrinkle state of a skin based on a skin image.SOLUTION: A wrinkle state-analyzing method includes: an image acquiring step S21 for acquiring a skin brightness image at a target analysis portion; a line detection step S22 which, from the skin brightness image acquired in the image acquiring step, extracts a linear texture image at each of a plurality of predetermined angles; an intensity extracting step S23 which, from each linear texture image extracted in the line detection step, extracts a line component intensity at each of predetermined angles; and an information generation step S24 which, by using each line component intensity extracted in the intensity extracting step, generates wrinkle state information of the skin at the target analysis portion.
