1. A tangible, non-transitory, computer-readable medium storing instructions executable by a processor of an endoscope, wherein the instructions comprises instructions to: instruct, using the processor, an imager in the endoscope to capture a first plurality of images at a first brightness level while a live video based at least in part on the first plurality of images is displayed; generate, using the processor, a baseline image by averaging or summing the first plurality of images to reduce a likelihood of a visual artifact caused by noise in one or more of the first plurality of images being present in the baseline image; instruct, using the processor, the imager to capture a second plurality of images at a plurality of brightness levels, wherein the plurality of brightness levels are different from the first brightness level; and generate, using the processor, a first high dynamic range image by modifying the baseline image based at least in part on the second plurality of images, wherein the first high dynamic range image comprises more unsaturated pixels than the baseline image.
