Abstract: A time-of-flight, ToF, camera for measuring distance information for objects of a scene includes a light source for emitting modulated light signals for illuminating the objects, an image sensor for capturing reflected light signals, and shutters for opening and closing the exposure of the image sensor. A pulse generator generates first pulses for switching the light source and second pulses for switching the shutters. A first driver amplifies the first pulses and outputs the same to the light source, and a second driver amplifies the second pulses and outputs the same to the shutters. A time measurement unit measures the propagation time of the pulses through the drivers and/or the pulse duration of the pulses output from the drivers. A processing unit generates a distance measurement image based on the captured reflected light signals to reduce the influence of phase errors on the distance measurement image.

Abstract: A camera housing/lens system comprises a camera housing for a camera and a lens. The camera housing/lens system further comprises a lock for locking the lens in position. The lock includes a stop member joined to the lens or the lens mount, and an elastic element arranged between the stop member and the lens mount or between the stop member and the lens, wherein the elastic element is compressed between the stop member and the lens mount or between the stop member and the lens to lock the lens in position. A gap remains between the stop member and the lens mount or between the stop member and the lens. This “elastic compression” allows the position of the lens to be finely adjusted in relation to the lens mount, without having to release the compression in order to do so.
