The invention relates to an automatic white balance detection system which adopts unique composition. Characteristics of a camera and characteristics of a black body curve are combined, and an operation of finding out white/gray point-achromatic regions is adopted to replace an existing region algorithm, weight algorithm and the like. Two regions of a warm color light source and a cold color light source are adopted according to light source characteristics; information of R/G and B/G, which is calculated in a changing mode by a variable image partitioning technology, is used as decision elements; a non-closed adjustable mode is adopted for a region of reference points, and a variable maximum and minimum approximate curve mode is determined. According to a detection color temperature range/detector color temperature accuracy, each region is subjected to color temperature calculation; colored regions in color temperature regions are removed and colored regions in brightness are removed, the number of white/gray regions obtained after the colored regions are removed is finally determined, and R and B gains and color temperatures of the determined white/gray achromatic regions are calculated. According to the automatic white balance detection system disclosed by the invention, the problem of influence of light source spectrum characteristics and characteristics of an image sensor, characteristics of an IRCF (Infrared Ray Cut Filter) and characteristics of a lens in a camera module of the image sensor is well solved, and accuracy of white balance is improved.
