Method and apparatus for compensating stray light caused by an object in a scene that is sensed by a time-of-flight camera

Abstract

A method for compensating stray light caused by an object in a scene that is sensed by a time-of-flight camera is provided. The method includes receiving an image of the scene from the time-of-flight camera. Further, the method includes controlling the time-of-flight camera to capture a reference image of the scene using a code modulated signal for illumination such that a measurement range of the time-of-flight camera is limited to a distance range around the object. The method additionally includes modifying the image of the scene or an image derived therefrom using the reference image to obtain a compensated image of the scene. The method includes outputting the compensated image.
