Method and device for controlling a red light camera
First Claim
1. A method for controlling a red-light camera at a traffic light by detecting vehicles which pass through the traffic light and making at least one recording when a vehicle passes during a period in which the red light of the traffic light is activated, is comprising detecting which part of the activation period the red light is on, and generating at least one record that is made in precisely that part of the activation period.

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.

- 6. Device for controlling a red-light camera at a traffic light, comprising a vehicle detector for detecting vehicles passing through a traffic light, an activation detector for determining a period in which the red light of the traffic light is activated, a signal generator connected to said vehicle detector and said red light detector wherein said signal generator produces a recording signal when a vehicle passes during an activation period, a red light detector for determining during which part of the activation period the red light is actually on, timing controller to generate a signal at the moment in time at which the generated recording signal is transmitted to the red-light camera.
