A camera system includes a sensor having a plurality of pixels sensitive to electromagnetic radiation; and an evaluator. The sensor is arranged behind a semi-transparent layer. The evaluator is configured to suppress an interference pattern occurring on the sensor by a pixel-by-pixel correction.

Camera system with interference pattern suppression

The disclosure relates to a time-of-flight camera comprising: a time-of-flight sensor having several time-of-flight pixels for determining a phase shift of emitted and captured light, distance values being determined in accordance with the detected phase shifts, characterised in that the time-of-flight camera has a memory in which parameters of a point spread function, which characterise the time-of-flight camera and the time-of-flight sensor, are stored; an evaluation unit which is designed to deploy a detected complex-valued image in Fourier space, in accordance with the stored point-spread function, and a complex-valued image corrected by diffused light is determined and the phase shifts or distance values are determined using the corrected complex-valued image.
