1. A method comprising: receiving first and second images depicting a scene and having substantially the same field of view, the first and second images comprising visible light (VL) image information and infrared (IR) image information, respectively; determining a transition area for an enhanced combined image based on a selection rule, wherein the transition area at least partly overlaps corresponding first and second sets of pixel coordinates of the first and second images, wherein the transition area is less than an entirety of the enhanced combined image; and generating the enhanced combined image by: assigning pixel values to the transition area based on a temperature-dependent mixing rule applied to pixel values of the corresponding pixel coordinates of the first and second images to provide an enhanced transition between the VL and IR image information of the scene, and assigning pixel values to pixel coordinates of the enhanced combined image bordering first and second sides of the transition area based on pixel values of the corresponding first or second set of pixel coordinates of the first image or the second image, respectively.
