オカメラを利用して測定する方法及び装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for measuring the depth of skin grooves and wrinkles on the skin surface using a video camera.

人間の皮膚の表面は、肉眼で観察した場合に平坦に見え

になっている皮溝あるいはしわなどによって細かな網目
状になっている。Although the surface of human skin may appear flat when observed with the naked eye, it actually has a fine network of raised mounds, low grooves, and wrinkles.

た不都合があった。In general, younger people have shallower skin, and with age, skin grooves tend to become deeper and wrinkles appear. Therefore,
Traditionally, for the purpose of medical diagnosis and determining the condition of the skin when applying makeup, methods have been used such as pressing silicone resin onto the skin and then measuring the depth of the skin grooves using a microscope after taking a mold of the skin. However, with these methods, it is not easy to use for reasons such as making a mold with silicone resin requires technical training, and measuring depth with a microscope requires advanced technology. had the disadvantage that it could not be measured.

There is a monitor TV that displays images, and a video pattern sensor that binarizes the image on the monitor TV and displays the binarized image on the binarization-only monitor TV. In addition to completing a device configured to allow the image of a dedicated monitor television to be set to an arbitrary threshold, he also invented a method for measuring the depth of skin grooves or wrinkles using that device. be. In other words, when the skin is exposed to light, the skin mounds appear brighter.1. Furthermore, the dermal groove system uses the fact that wrinkled areas appear dark to measure the depth of cutaneous grooves and the like based on the difference in brightness.

２に入力できるように構成されている。The invention will now be described in detail according to the illustrated embodiments. In the figure, 1 is a video camera for video analysis,
A C-mount lens 2 is attached to the video camera 1 to increase the magnification from 10 to 100 times. Furthermore, a rigid fiberscope 5 is attached to the tip of the C-mount lens 2, which uses a light source device 3 as a light source and has a built-in optical glass fiber 4 configured to illuminate the skin surface about 10 degrees away from the outer periphery of the tip. It is being The video camera 1 is connected to a video tape recorder 6, and the video tape recorder 6 is further connected to a monitor television 7 on which the video is displayed. Next, monitor TV 7
is connected to a video pattern sensor 9 that binarizes the video signal and displays a binarized image on a television 8 dedicated to binarization. This video pattern sensor 9 has a knob 10 that can set the brightness of the binarized image of the monitor television 8 to an arbitrary threshold, and an indicator 11 that displays the value of the knob IO. Roughly speaking, in this embodiment, the numerical value of the indicator 11 is changed to
It is configured so that it can be input to 2.

うち最も暗い部分とを決める。Measurement is performed as follows using the apparatus according to the present invention in the configuration as described above. A fiberscope 5 attached to a video camera 1 is applied to the surface of the skin, and while irradiating light with an optical glass fiber 4, the skin surface is magnified by the video camera 1 at a predetermined magnification (for example, 100 times) and displayed on a monitor television 7. Project. As shown in Photo 1, which was submitted as reference material, the projected image of the skin surface shows that the skin grooves are dark and the skin mounds are bright and dark. The video signal of this monitor television 7 is inputted to a video pattern sensor 9Vc, and the image is binarized and displayed on a monitor television 8 dedicated to binarization, as shown in photo 2 submitted as reference material. Next, the user looks at the monitor television 7 and determines the brightest part of the skin mound and the darkest part of the skin grooves surrounding the skin mound or the wrinkles close to the skin mound.

Also, read the value of the 10th knob indicator 11 when the predetermined brightest part becomes black on the binarization-only monitor television 8 (the value is taken as Lmax). These measured values, [, min, and LmaX, are each input into the computer 12, and the difference between LmaX and Lmin (brightness difference) is multiplied by a conversion coefficient K between brightness and depth calculated in advance to calculate the skin groove or Calculate the depth of the wrinkles.
