3 results about "Exposure control" patented technology

The invention discloses an automatic exposure control method and device for imaging equipment. Each exposure parameter is divided into a plurality of sections, each section is called as a sub exposure line, and the sub exposure lines are sequenced and then combined to form a main exposure line of the imaging equipment. After the imaging equipment is turned on, the deviation between a current screen brightness and a target screen brightness is judged, the exposure parameters are adjusted according to the main exposure line of the imaging equipment if the deviation exists, and the exposure parameters are not adjusted if the current screen brightness is within the range of the target screen brightness. The automatic exposure control device for the imaging equipment comprises a control module, a brightness evaluation module and an exposure parameter adjusting module. The method and the device are universal, the exposure parameters can be adjusted into reasonable values under a normal lighting condition, imaging effects are optimized, the exposure parameters can be adjusted into maximum values under an extreme lighting condition, the imaging effects cannot be worse than those of a traditional scheme, and overexposure can be effectively suppressed.
