The stereoscopic recording/analyzing system for the skin surface image has been developed. Two sets of video camera with a magnifying lens are installed in the probe for recording the right and left images (area of 2.9×2.2mm) synchronously. The stereoscopic images can be recorded by a 2-channel video cassette recorder. These images are synthesized on the screen and they are visible using a binocular stereo vision method. The system can replay the image of the skin surface with high fidelity, which is useful in cosmetic product tests for assisting researchers to evaluate the skin condition visually, The system can also measure topographic dimensions by an image processing method. The approximate diameters and depths of hair pores were obtained, in which the depth was calculated from the disparity between the right and left images with the use of trigonometry. The 3-D data were analyzed to grade the pore size and to categorize the skin for cosmetic counseling.
