Abstract: 3D time-of-flight camera and a corresponding method for acquiring information about a scene. To increase the frame rate, the proposed camera comprises a radiation source, a radiation detector comprising one or more pixels, wherein a pixel comprises two or more detection units each detecting samples of a sample set of two or more samples and an evaluation unit that evaluates said sample sets of said two or more detection units and generates scene-related information from said sample sets. Said evaluation unit comprises a rectification unit that rectifies a subset of samples of said sample sets by use of a predetermined rectification operator defining a correlation between samples detected by two different detection units of a particular pixel, and an information value calculator that determines an information value of said scene-related information from said subset of rectified samples and the remaining samples of the sample sets.

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.
