Abstract
A device and method that inhibits the ability of photographic equipment from obtaining a recognizable picture upon its recording media, of areas of a vehicle equipped with this invention. The leading edge or beginning of the photographic equipment's photoflash is detected by the photoflash detector cicuit group (50). A xenon reply flash (30) is immediately output towards the photographic equipment's general location, for the remainder of the photographs exposure time, rendering sections of the photograph unrecognizable.
