Claim 4:
5. The method according to claim 1, wherein the fusing the first image and the second image according to the image fusion factor to obtain the dehazed image comprises:
mapping the first image from an RGB space to a YUV space, to obtain a mapped brightness value and a mapped chrominance value of each pixel;
calculating a first brightness result of each pixel based on the image fusion factor and the second pixel value of each pixel of the second image, and calculating a second brightness result of each pixel using the image fusion factor and the mapped brightness value;
superposing the first brightness result and the second brightness result, to obtain fused brightness information of each pixel; and
reversely mapping the fused brightness information and the mapped chrominance value from the YUV space to the RGB space, to obtain the dehazed image.
