Abstract
A surgical microscope system includes a camera 9 that is turnable around an optical axis K of the camera 9 to optionally select a photographing orientation. The camera 9 is able to pick up an electronic image of an affected part T in an orientation in which a main doctor sees the affected part T, or in an orientation in which an assistant, who is present at a different position from the main doctor, sees the affected part T, or in any other orientation. The electronic image picked up by the camera 9 in a selected orientation is stereoscopically observable with an electronic image display unit 2.
