摘要

A light control system comprises a processing by, which light sources in a acquired image either as a self-luminous objects or different reflecting objects. Each pixel is obtained, which the obtained image is formed into a plurality of groups according to the brightness of each pixel, and it is a histogram is generated which the relationship of the brightness and the number of pixels in each group are specified. If the number of pixels corresponding to the lightest group consisting of lower than the number of pixels corresponding to the other groups, the presence of a self-luminous object in the acquired image is determined, and if the number of pixels corresponding to the lighter group consisting of greater than the number of pixels corresponding to the other groups, the presence of a reflecting object in the acquired image.
