1. A surgical microscope system comprising:
a microscope configured to image an operative site of a patient, and output an image signal; and
a support configured to support the microscope at a distal end, wherein
the support includes a first arm, a first joint, a second arm, and a second joint, the second arm supporting a proximal end of the first arm at the first joint rotatably around a first rotation axis of the first joint orthogonal to a vertical direction and the second arm being supported at the second joint rotatably around a second rotation axis of the second joint orthogonal to the vertical direction,
wherein the support is configured such that 200 (mm)<V(1−cos(r2max)), where a length of the second arm is represented as V and a maximum value of a rotation angle of the second arm away from the vertical direction is represented as r2max, and
the support includes a rotary shaft at the second joint, the rotary shaft supporting the second arm rotatably around a rotation axis parallel to an extending direction of the second arm.
