Beschreibung
Zusammenfassung:	A hand-held measurement device for appearance analysis comprises a measurement array (MA) which includes a plurality of illumination means (21-27) for applying illumination light to a measurement field in at least three illumination directions and a plurality of pick-up means (31-33) for capturing measurement light in at least one observation direction. The illumination directions and the observation directions lie in a common system plane (SP). At least one pick-up means (332) is embodied to spectrally gauge the measurement light in a locally integral way, and at least one imaging pick-up means (33) is embodied to gauge the measurement light in a locally resolved way. The spectral pick-up means (32) and the locally resolving pick-up means (33) are arranged so as to receive the measurement light reflected by the measurement field under the same observation conditions and in particular from the same observation direction.
