Abstract
A camera device acquires optical properties in two or more different wavelength ranges as well as spatial structure properties of an object. The device includes a beam splitter for splitting light coming from an object into the two or more different wavelength ranges. A first image sensor generates a first sensor signal related to a first predetermined wavelength range. A first signal processing device generates a first intensity image signal and a distance image signal using information about the temporal modulation of illumination light (M) and the first sensor signal. At least one second image sensor generates a second intensity image signal for a second predetermined wavelength range. A second signal processing device generates a color image signal from the first intensity image signal and the second intensity image signal.
