Abstract: The embodiments of the present invention provide an image processing method and apparatus and electronic device. The image processing method includes: acquiring a visible image and an infrared image of a captured object; decomposing the visible image to generate a base image layer containing low frequency components; decomposing the infrared image to generate a detail image layer containing high frequency components; and combining the base image layer and the detail image layer, so as to generate a combined image of the captured object. In the embodiments of the present invention, a combined image with the surface of a captured object being smooth and important characteristic portions being kept without distortion can be obtained.
