  • Patent number: 8526689
    Abstract: On the methods of creating corneocyte specimen for providing useful information for appropriate selection of cosmetic products or assessment of the skin condition, it is intended to provide a method of indicating an unstained image of corneocytes or the like in an observable pseudocolor in a method of creating corneocyte specimen, without resorting to staining the corneocyte specimen. The state of corneocytes of skin is input into a computer as an enlarged image by using, for example, a digital microscope. Then, the RGB values of the individual pixels in the image are converted with the use of a conversion system such as a conversion formula, a conversion table or a conversion chart and an image is indicated in a pseudocolor by using the individual RGB values converted.
    Type: Grant
