Abstract
Angular speed sensors and acceleration sensors are built into the casing of a video-type stereoscopic microscope. The angle of rotation of the stereoscopic microscope detected by the angular speed sensors and the amount of shift of the stereoscopic microscope detected by the acceleration sensors are input to a microscope control unit. This microscope control unit controls a vibration compensator based on the result of the detection. The vibration compensator shifts a lens within a plane orthogonal to its the optical axis so that object light from a field is deflected to a direction parallel to the optical axes of individual zoom optical systems. The vertical width A.sub.V of the field and the working distance L of this video microscope satisfy the following inequality: 1/A.sub.V >1/(11.46+0.011.times.L).
