Claim:
1. 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; wherein in a power saving mode the time-of-flight sensor is operated for motion detection with a control signal, wherein each of the at least two integration nodes are triggered by means of the control signal and wherein the frequency of the control signal 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 at least two integration nodes.
