Abstract

The method involves arranging a light-diminishing filter (9) in a path of rays of a flashgun (5) that illuminates a vehicle. The light of the flashgun is diminished by the filter, where the light impinges on a strongly reflecting number plate of the vehicle. Light permeability of a translucent component e.g. liquid crystal display (LCD) surface, is electronically steered in an area that illuminates the number plate. An independent claim is also included for a device for monitoring of road traffic.
