Abstract
Systems and methods of presenting an image of a portion of a surgical scene on a display device associated with an endoscope include receiving, from the endoscope, a source image representing a view of the surgical scene as captured using the endoscope. The systems and methods further include devices configured to, by one or more processing devices, apply a distortion correction to at least a portion of the source image to generate a modified image, wherein the modified image includes a central region, and a peripheral region surrounding the central region, wherein a first degree of distortion correction in the central region is higher than a second degree of distortion correction in the peripheral region. The systems and methods further include devices configured to present the modified image on the display device associated with the endoscope.
