The invention reveals a license plate shooting device and an image white balance adjusting method. The license plate shooting device comprises an image sensing module, an identification module, a database and a processing module. The image sensing module senses a scene to generate an image. The identification module identifies at least one object in the image and license plate color characteristics included in the object so as to generate identification data. The database stores a plurality of sets of reference object data and corresponding reference license plate color characteristics thereof. The processing module searches for corresponding reference object data and reference license plate color characteristics in the database according to the identification data, substitutes the license plate color characteristics with the reference license plate color characteristics and further carries out white balance adjustment on the image.
Description
technical field [0001] The invention relates to a license plate camera device and its image white balance adjustment method, in particular to a license plate camera device and its image white balance adjustment method for adjusting the white balance of captured images by utilizing the color of the license plate.
