Abstract

The present invention relates to a 3D time-of-flight camera for acquiring information about a scene, in particular for acquiring depth images of a scene, information about phase shifts of a scene or environmental information about the scene. The proposed camera particularly compensates motion artifacts by real-time identification of affected pixels and, preferably, corrects its data before actually calculating the desired scene-related information values from the raw data values obtained from radiation reflected by the scene.
