Abstract
A TOF camera apparatus for transmitting light signals and recording the light that is scattered back at an object and also for determining the distance of the TOF camera apparatus from the object is proposed, wherein the TOF camera apparatus comprises: a transmitter for transmitting light signals, a receiver for detecting the light scattered back at the object, embodied in the form of a pixel matrix having at least one pixel, a modulation device for producing a modulation signal in order to modulate light signals that are to be transmitted by the transmitter, an evaluation device for evaluating the light detected by the receiver, which evaluation device is connected to the modulation device to obtain the modulation signal for evaluating and determining the distance. In order to make possible particularly reliable error detection, a check apparatus for error detection in at least one of the pixels is provided.
