Abstract
A digital camera has a 2D image sensor designed as a CCD or CMOS sensor that can be used to measure distances based on a runtime measurement in synchronization with a pulsed infrared source. The measured distances are used to carry out a 3D reconstruction of a detected object. The digital camera does not have to have an infrared cut-off filter; however, it can have an infrared cut-off filter that can be dynamically activated in full or in part or deactivated in relation to pixels of the image sensor. In the latter event, individual areas of the image sensor, for which the infrared cut-off filter is deactivated, are used for the 3D reconstruction or for images in the infrared range. The remaining areas of the sensor are used for images of high color quality in the visible light spectrum. In the event that no infrared cut-off filter is present, individual areas of the image sensor are used for the 3D reconstruction or for images in the infrared range. The remaining areas of the sensor are used for images in the visible light spectrum.
