  • Method for analyzing skin surface and apparatus therefor
    Patent number: 5991433
    Abstract: A method and apparatus for analyzing skin surface conditions which includes transferring horny cells from a skin surface of a subject onto an adhesive face of a base sheet. In addition, a learning-type image measurement system equipped with autocorrelation mask patterns is executed on a morphology of the horny cells in the image, thus judging at least one of a degree of overlapping, a degree of ellipticity and a degree of area of the horny cells. Further, the skin surface conditions are analyzed using this information.
