The invention discloses an adaptive global dark channel prior dehazing method for a bright area. The method comprises the following steps; 1, a global dark channel value of a haze image I(x) is solved; 2, a fuzzy logic controller is built to obtain a tolerance parameter and a transmittance adjustment factor; 3, the tolerance parameter is used for dividing the haze image into a bright area and a non-bright area; 4, the atmospheric light intensity A is solved; 5; the transmittance is solved; and 6, the tolerance parameter, the transmittance and the atmospheric light intensity are used to obtain a restored image. Problems of block effects, Halo phenomena, color distortion and the like caused by bright area distortion and block processing can be effectively solved, good dehazing effects can be acquired in a condition of not increasing exposure treatment, objective evaluation results for three aspects of the image contrast ratio, the information entropy and the average gradient are obviously better than those of other comparison algorithms, and the operation efficiency is greatly enhanced.
