1. An image fusion device,
a graphic processor configured to:
convert a superimposed image into a feature image after a plurality of images of a same scene are captured respectively under different colored light beams and then aligned with each other to form the superimposed image;
read and identify colors of a plurality of pixel points in a plurality of pixel regions of the feature image;
compare color depths of the plurality of pixel points in each of the plurality of pixel regions of the feature image with each other;
determine a largest one of the color depths of the plurality of pixel points that are classified in a same one of a plurality of color tones in each of the plurality of pixel regions, as a maximum color depth of the same one of the plurality of color tones in each of the plurality of pixel regions of the feature image;
analyze a relationship between the color depth of each of the plurality of pixel points and the maximum color depth that are classified in the same one of the plurality of color tones in each of the plurality of pixel regions of the feature image; and
determine whether or not to adjust the color depth of each of the plurality of pixel points of the feature image, according to the relationship between the color depth of each of the plurality of pixel points and the maximum color depth that are classified in the same one of the plurality of color tones in each of the plurality of pixel regions of the feature image;
wherein, when the relationship between the color depth of any one of the plurality of pixel points and the maximum color depth that are classified in the same one of the plurality of color tones in a same one of the plurality of pixel regions of the feature image does not meet a preset relationship, the graphic processor adjusts the color depth of the one of the plurality of pixel points according to the maximum color depth, and graphic processor generates the fusion image according to the feature image on which all of the plurality of pixel regions are adjusted.
