Abstract
A method of operating a surgical microscope includes detecting an amount of movement of a body portion of a user, and performing movements of a camera and changes in a magnification based on the detected movements of the body portion. The amounts of these movements and changes decrease with increasing magnification provided by the surgical microscope, they decrease with decreasing distance of the body portion of the user from the display, and they decrease with decreasing distance of the cameras from the field of view of the cameras.
