A method for measuring the sulcus cutis or the depth of folds as well as an apparatus for carrying out the method

摘要

the invention concerns a procedure for the measurement of the cutis or the depth of wrinkles on the skin surface using a video camera (1) and a device to implement the procedure.using a video camera (1), the surface of the skin by a factor of 10 to 100 is enlarged and the enlarged image is an image with two helligkeitswerten (2wertiges picture) implemented over a bildmustersensor (9) on an exclusively for 2wertige images for f ernsehbildschirm (8) projecting.then, a handknopf to determine the threshold is controlled and the difference between the value to a control unit (11) in which the darkest point on the television screen (8) to white, and the value in the control unit (11), in which the brightest part gets dark, as oh, the difference in brightness.by multiplying the difference in the brightness of the conversion factor to the difference in the brightness and the depth of the depth of the wrinkles can be calculated.
