2. Description of the Related Art For example, in a speeding control system for monitoring the speed of a vehicle and photographing a speeding vehicle, the speed of a vehicle traveling on an installed route is measured, and the speed exceeds a preset speed threshold value. When it is determined that the vehicle is present, the front surface, the rear surface, or both the front and rear surfaces of the vehicle are photographed. License plate information is automatically generated by image processing from the license plate imprinted on the captured image and is integrated with the image. The enforcement personnel in charge of enforcement of traffic laws read the accumulated images and license plate information, for example, every few days, search and identify the owner from the vehicle registration information based on the license plate information, and include it in the image. The driver's appearance is used to identify the driver during overspeed driving.
