The invention discloses a method and a device of automatically optimizing an orbital shooting effect, belonging to the field of digital imaging technique. The method comprises the following steps of: when orbital shooting is finished, determining pixel points of a shot orbital image in a non-orbital region; and carrying out darkening processing on the pixel points in the non-orbital region. By adopting the method and the device, when orbital shooting is finished, the non-orbital region in the shot orbital image is determined according to a preset optimization option, and then darkening processing is carried out on the determined non-orbital region, so that an orbit can be highlighted to a key point of the whole shot orbital image, thus the shot orbital image is more fantastical; furthermore, the whole optimization process does not need user participation, so that the time for a user to carry out post-processing on the orbital image is reduced, meanwhile, the optimization is directly finished at a shooting site, the user can timely discover whether the shooting effect is ideal and can timely reshoot when the shooting effect is not ideal, so that the user experience is improved.
