Abstract
The invention relates to a method for controlling a red-light camera at a traffic light, the lights of which are formed by an array of intermittently operated LEDs. Vehicles which pass through the traffic light are detected and a recording is made when a vehicle passes during a period in which the red light of the traffic light is activated. There is herein detected for which part of the activation period the LEDs of the red light are actually on, and the recording is made in precisely that part of the activation period. The moment of the recording can further be corrected for a response time of the red-light camera. The invention further relates to a device for performing this method.
