Claims15
A device for acquiring a characteristic image of a body, comprising:
- an image sensor comprising a plurality of photo-sensitive cells;
- and
- a layer of a material having its color varying due to the variations of a physical parameter characteristic of said body, coating a surface of the sensor,
- wherein the sensor comprises a substrate having the photo-sensitive cells arranged inside and/or on top of it,
- and wherein the layer is arranged on the side of the surface of the substrate opposite to the photosensitive cells.
A device for acquiring a characteristic image of a body, comprising:
- an image sensor comprising a plurality of photo-sensitive cells;
- and
- a layer of a material having its color varying due to the variations of a physical parameter characteristic of said body, coating a surface of the sensor;
- wherein the layer is discontinuous and is located only opposite the photosensitive cells of the sensor.
A method of using a device for acquiring a characteristic image of a body, the device comprising an image sensor comprising a plurality of photosensitive cells, and a layer of a material having its color varying due to the variations of a physical parameter characteristic of said body, coating a surface of the sensor, the method comprising the successive steps of:
- placing the body for which an image is desired to be acquired in contact or almost in contact with the layer;
- removing the body from the layer;
- and
- acquiring an image of the layer by means of the sensor.
