Arrangement for the Optical Recording of Live Skin Areas of Human Autopodia and of Documents
First Claim
1. An arrangement for optical recording of live skin areas of human autopodia and of a document, comprising:
- a layer body with a sensor layer comprising light-sensitive elements arranged in a two-dimensional regular pixel raster;
a transparent protective layer above the two-dimensional pixel raster of light-sensitive elements of the sensor layer, the protective layer having an outer surface of the layer body parallel to and at a defined distance from the light-sensitive elements, the outer surface providing a placement surface for the live skin areas of the human autopodia or for the document to be recorded;
an area light source from which portions of light propagating from a direction of the sensor layer through the protective layer and the placement surface can be coupled into the skin areas or onto the document located on the placement surface, wherein all layers of the layer body located between the area light source and the placement surface transmit at least portions of light of a required wavelength range;
wherein the layer body is integrated in a mobile image capture device comprising;
at least one display for displaying user guidance for a user, the display being formed as a layer of the layer body;
an internal power supply for powering the mobile image capture device for a desired period of use without an external power feed;
the layer body supplemented under the sensor layer by the area light source as a light-emitting layer, wherein the light-emitting layer is configured to emit;
light in a first angle range such that portions of light in the protective layer are internally reflected at the placement surface to record skin areas placed on the placement surface using the principle of frustrated total internal reflection, andlight in a second angle range such that portions of light illuminate the document placed on the placement surface through the placement surface;
the image capture device having an electronic controlling and data processing unit for controlling the light-emitting layer, for image read out, preprocessing captured image data, and for reducing the captured image data for wirelessly sending the captured image data to a further electronic device; and
the mobile image capture device being coupled to the further electronic device for image data processing via an interface for wireless data transmission and communication.

Abstract
An arrangement and method for optical recording of live skin areas of human autopodia and documents has a layer body comprising sensor layer with light-sensitive elements in regular pixel rasters, transparent protective layer above the sensor layer as placement surface for skin areas or documents is integrated in a mobile image capture device having at least one display for user guidance and an internal power supply. The layer body has an area light-emitting layer under the sensor layer to emit light in a first angle range for frustrated total internal reflection at the placement surface when autopodia are placed thereon and to emit in a second angle range to illuminate documents on the placement surface. A controlling and data processing unit handles preprocessing and reducing captured image data and an electronic interface for wireless coupling of the image capture device with a further electronic device for image data processing.
