Abstract

A device for capturing prints of areas of skin of human autopodia or parts thereof supplied with blood, including: a contact surface for placing on an area of skin; a composite containing a sensor layer with light-sensitive sensor elements arranged in a first pixel grid; and light-emitting elements. The light-emitting elements are arranged to form a second pixel grid. They emit light in a frequency range for which the sensor layer is at least partially transparent, with the result that light emitted from the contact surface in the direction of an area of skin can be coupled into it. The light-emitting elements can be actuated individually or in groups and thus switched on and off, with the result that these light-emitting elements can be actuated for the representation of visual information in dependence on intensity values determined by the light-sensitive sensor elements for display on the contact surface.
