摘要： 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.

摘要： A method of operating a surgical microscope includes detecting a position of a user, and setting a rotation angle of a camera about its main axis such that it is between a first angle and a second angle. The first angle is the rotation angle required to display a first straight object as a vertical line, and the second angle is the rotation angle required to display a second straight object as a horizontal line. The first object extends along a first line arranged in a vertical plane containing a line connecting the position of the user with the field of view. The first line is horizontal and traverses the field of view. The second object extends along a second line traversing the field of view. The second line is horizontal and perpendicular to the first line.

摘要： 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.

摘要： A method of operating a surgical microscope includes detecting a direction of gaze of a user and detecting an amount of a movement of a head of the user. The movement of the head of the user is of a translatory movement type and a rotatory movement type. Amounts of movements or rotations of the camera or changes in the magnification are performed based on the detected amount of a movement of the head of the user.
