Abstract
A method for operating a time-of-flight camera including a time-of-flight sensor comprising an array of time-of-flight pixels with at least two integration nodes, wherein in a 3D mode the time-of-flight sensor and an illumination means are operated by means of a modulation signal and on the basis of the charges accumulated at the integration nodes distance values are determined, characterized in that in a power saving mode the time-of-flight sensor is operated with a control signal for motion detection, the frequency of which is lower than a lowest frequency of the modulation signal for a distance determination in the 3D mode, wherein an object motion is determined based on a differential value at the integration nodes is provided.
