Abstract

The invention relates to a method of acquiring an image of a non-dermatoglyphic zone of the skin or the hair by means of acquisition apparatus comprising a non-optical sensor.

Claims

1. An assembly comprising:

image acquisition apparatus for acquiring an image of at least one of a non-dermatoglyphic zone of the skin and a zone of the hair in order to determine certain parameters of said zone and/or perform a diagnosis, said acquisition apparatus including a portable non-optical sensor arranged to be brought into contact with at least one of a non-dermatoglyphic zone of the skin and a zone of the hair; and

a computer tool enabling information to be extracted from signals delivered by the non-optical sensor concerning microrelief of said zone, said information relating to a state of one of the skin and the hair,

wherein the non-optical sensor includes an active surface that is sensitive to capacitance.

2. The assembly according to claim 1, wherein said non-optical sensor includes an active surface that is sensitive to one of an electrical property, temperature and pressure.

3. The assembly according to claim 1, wherein the non-optical sensor includes a plurality of juxtaposed rows of detection cells that are sensitive to capacitance.

4. An assembly comprising:

image acquisition apparatus for acquiring an image of a non-dermatoglyphic zone of the skin in order to determine certain parameters of said zone and/or perform a diagnosis, said acquisition apparatus including a portable non-optical sensor arranged to be brought into contact with said non-dermatoglyphic zone of the skin; and

a computer tool enabling information to be extracted from signals delivered by the non-optical sensor concerning microrelief of said zone, said information relating to a state of the skin,

wherein the non-optical sensor includes an active surface that is sensitive to capacitance.
