In order to evaluate aging of skin texture objectively

a kind of automatic measuring system based on image sensor is introduced. Firstly

under the condition of light

skin images collection is realized by CMOS image sensor through the photoelectric conversion. Then

the collected images are processed by using image processing technology. Finally

each measurement index

such as mean areas and number of skin ridges

depth of skin channel

and so on are calculated quantitatively with software

and with the help of statistics methods

characteristics of each measurement index are analyzed. The whole system integrates acquisition and processing with calculation

which has advantages such as low power consumption

high stability

wide applicability

simple operation

etc.
