Abstract

A 3D-camera (10) is provided, having at least one image sensor (14a-b) and at least one illumination unit (100) which comprises a light source and which is configured for generating an irregular illumination pattern (20) in an illumination area (12) of the 3D-camera (10). The light source comprises a semiconductor array (104) having a plurality of individual emitter elements (106) in an irregular arrangement, and a respective individual emitter element (106) generates a pattern element (112) of the irregular illumination pattern (20).
