摘要： A controller (442) for a video processing system (400). The controller (442) is configured to receive acquired images; recognise a looking-stimulus by determining that an acquired image shows a user to be looking towards the camera or a display screen; and/or recognise a present-stimulus by determining that a user is visible in an acquired image an acquired image shows a user that is not looking towards the camera or the display screen. The controller (442) can then generate a video stream based on the acquired images, and set a characteristic of the video stream based on the recognised looking-stimulus or the present-stimulus.
