摘要

Process and device for measuring the recessed parts (sulcus cutis) of human skin. / p & & p & the image of the surface of the skin is an enlarged scale of 10 to 100 times with the aid of a video camera 1, the video image are assigned a larger scale, two types of values and the image treated is projected on a screen of the television 8 intended for monitoring the video image treated by means of a video sensor 9 of the pattern. Then, a button 10 for adjusting the threshold is actuated in order to measure the difference between the value posted on an indicator 11 when the part, the darker appearing on the station 8 becomes clear and the value of the indicator 11 when the part, the more clear from the station 8 becomes dark (difference of brightness). The depth of the grooves of the skin may be calculated by multiplying the difference of brightness by a factor of conversion of the difference of brightness and depth.
