Abstract

A method of operating a surgical microscope includes receiving an instruction to move the camera relative to the object, operating a zoom lens to zoom out and displaying images obtained by processing images recorded by the camera such that centers of the displayed images correspond to a target position within the recorded images and such that the magnification of the object displayed in the images is the initial magnification, wherein the target position is displaced within the recorded images relative to the first position, and operating actuators to move the camera.
