Image fusion method and mobile equipment

The invention discloses an image fusion method. The method is used for processing a first image and a second image shot from the same object simultaneously, wherein the first image has brightness information, and the second image has color information. The method comprises: for each pixel in the first image, searching whether a pixel having the same content exists from the second image; if existing, endowing the corresponding pixels in the first image with the color information of the found pixels in the second image; performing super-pixel partition on the first image according to the brightness information, and in each super-pixel area, screening the color information according to a predetermined condition to obtain a third image; filling the pixels having no color information in the third image with colors according to a predetermined sampling method, so that all pixels have color information; and fusing the color information of the corresponding pixels with the brightness information of the third image to
