Abstract: A system may access an image that is captured by an imaging device and that depicts an operational scene illuminated by close-range light. The system may also access a depth map of the operational scene that includes depth data corresponding to each pixel in the image. Based on the depth map, the system may determine a far-range lighting coefficient for each pixel in the image based on a relationship between the corresponding depth data included in the depth map for that respective pixel and a target distance to a virtual light source that is to be simulated to be illuminating the operational scene. Based on the image and these far-range lighting coefficients, the system may generate a processed image depicting the operational scene as being illuminated by the virtual light source and may provide the processed image for presentation on a display screen. Corresponding systems and methods are also disclosed.

Abstract: A lighting emulation system accesses an image that is captured by an imaging device and that depicts an operational scene illuminated by close-range light. The lighting emulation system accesses a depth map of the operational scene that includes depth data corresponding to each pixel in the image. Based on the depth map, the lighting emulation system determines a far-range lighting coefficient for each pixel in the image. Specifically, the far-range lighting coefficient for each respective pixel is determined based on the corresponding depth data included in the depth map for that respective pixel. Based on the image and the far-range lighting coefficient for each pixel in the image, the lighting emulation system generates a processed image depicting the operational scene as illuminated by far-range lighting, and provides the processed image for presentation on a display screen.
