1. A camera system, the camera system comprising:
a sensor having a plurality of pixels sensitive to electromagnetic radiation;
an evaluator; and
an illumination arranged behind a semi-transparent layer,
wherein the sensor is arranged behind the semi-transparent layer,
wherein the evaluator is configured to suppress an interference pattern occurring on the sensor by a pixel-by-pixel correction, and
wherein the interference pattern suppression or a correction matrix is configured to take into account distance-dependent interference patterns.
