Image fusion method and endoscope equipment

The invention provides an image fusion method and endoscope equipment. Comprising the steps that based on a white light image of human tissue, color photosensitive characteristic parameters of the white light image are determined, and the white light image is an image obtained after the human tissue is irradiated by light emitted by a white light source; performing pseudo-color conversion on the black-and-white image by using the pixel value of each pixel point in the black-and-white image of the human tissue and the color photosensitive characteristic parameter of the white light image to obtain a fluorescent image, the black-and-white image being an image obtained after the human tissue is irradiated by light emitted by a fluorescent light source; and carrying out image fusion on the fluorescence image and the white light image to obtain a fluorescence image after color restoration. Therefore, according to the invention, the color photosensitive characteristic parameter of the white light image is taken as
