Abstract

The invention discloses a license plate photographic device and an adjusting method of image exposure of the license plate photographic device. The license plate photographic device shoots a scene, and the license plate photographic device comprises an image sensing module, an identifying module and a processing module. The image sensing module carries out sensing on the scene to generate an image. The identifying module identifies at least one vehicle object from the image. The processing module carries out exposure adjustment on all vehicle objects to respectively generate an exposure adjustment vehicle object, the identifying module identifies a license plate object from the exposure adjustment vehicle objects, and the processing module carries out exposure adjustment on all the license plate objects.

Description

technical field [0001] The present invention relates to a license plate camera device and its image exposure adjustment method, in particular to a license plate camera device and its image exposure adjustment method for separately adjusting the exposure of individual license plate images. Background technique [0002] With the growing popularity of scientific case handling, many vehicle accidents that occurred in big cities can be cleared through the video recording of the intersection monitor. However, the density of monitors is limited after all, and in some cases it may not be possible to clearly record images of the accident scene. In addition, once the vehicle enters the suburbs or scenic areas, the setting of monitors is even rarer. In case of an accident, the responsibility for the accident can only be clarified through on-site investigation by forensic personnel. Therefore, more and more people choose to install a driving recorder in the car to protect their legal r...
