METHOD FOR GENERATING VIDEO SIGNAL FOR AUTOMATIC VEHICLE NUMBER IDENTIFYING SYSTEM |
摘要 |
FIELD: automation and computer engineering. SUBSTANCE: more flexible adjustment of video equipment depending on illumination of field of vision is attained due to the fact that cyclic exposure is effected in video camera by four adjustable exposure times and digital video signal is additionally divided into signals corresponding to superlow and superhigh exposure, each of four generated video signals being subjected to adaptive amplification and gamma correction; one of them is used for controlling lens diaphragm. EFFECT: enhanced probability of vehicle number identification. 1 cl, 1 dwg
