Arrangement for the optical recording of live skin areas of human autopodia and of documents

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 below the sensor layer, wherein the sensor layer comprises transparent regions so that proportions of at least 10% of light of the at least one display can pass through the sensor layer;
• the layer body supplemented under the sensor layer by the area light source formed as a light-emitting layer comprising two layer-shaped light sources, wherein:
• a first layer-shaped light source 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, and
• a second layer-shaped light source is configured to emit light in a second angle range such that portions of light illuminate the document placed on the placement surface through the placement surface;
• the second layer-shaped light source being formed by the at least one display for displaying user guidance and being further used for the light emission in said second angle range by exploiting emission of diffuse backlight for illuminating the documents placed on the placement surface;
• the image capture device having an electronic controlling and data processing unit for controlling the light emission of the first and the second layer-shaped light sources, for image read out, preprocessing, and for 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, quality assessment and data management.
