Defogging processing method and display device for video stream images

The embodiment of the invention discloses a defogging processing method and a display device for video stream images, relates to the field of image processing, and provides a method synchronously performing defogging processing at the display screen end in real time based on an average filtering algorithm. The defogging processing method comprises the steps of obtaining a to-be-processed image frame; determining the environmental light intensity of all pixels in the to-be-processed image frame according to all the pixels in the to-be-process image frame and the distribution of the adjacent pixels of all the pixels on a color space, and determining global atmospheric light of the to-be-processed image frame according to the distribution of all pixels in a last image frame of the to-be-processed image frame in a color space and the distribution of all pixels of the last image frame after defogging processing is performed in a color space; performing defogging processing on all the pixels in the to-be-processed image frame according to the environmental light intensity and the global atmospheric light to obtain image frame data of the to-be-processed image frame after defogging processing is performed; accordingly, the above functions are achieved.
