Abstract: Disclosed are aspects of a camera assembly, including a sensor for sampling image data in a sampling step. A lens is provided for focussing light onto the sensor. A window is supported in front of the lens. The window includes a transparency changing material for varying the transmittance of light through the window in response to an input signal. The camera assembly is configured to thereby increase the transmittance of light through the window during the sampling step of the sensor.

Abstract: The system for in-vehicle video conferencing (200) includes: an acquisition module (201) for acquiring data of facial characteristic points of a user (A) in the vehicle (100) during a video conference call in which said user (A) participates; a video synthesizer (202A) for producing an artificial video of the face of the user in the vehicle (100) from the acquired data of facial characteristic points, a communication device (203) for transmitting the artificial video of the face of the user through a communication network (300) in the video conference call.
