         2 . The medical observation device according to  claim 1 , wherein
 the control unit decides a vibration mode of the observation unit according to a state of the support unit, and conducts the image shake correction based additionally on the decided vibration mode.   
     
     
         3 . The medical observation device according to  claim 2 , further comprising:
 an operating unit configured to change an operating mode of the support unit, wherein   the vibration mode is decided according to a user operation on the operating unit.   
     
     
         4 . The medical observation device according to  claim 2 , wherein
 the vibration mode is decided as a mode of vibration including a vibration characteristic of at least one from among a footstep vibration produced by a person walking inside an operating room, an observation unit movement vibration produced by the observation unit moving, and an observation unit locking vibration produced by the observation unit being locked at a position after moving.   
     
     
         5 . The medical observation device according to  claim 1 , wherein
 the observation unit includes an imaging unit that generates an image by sensing observation light with an image sensor, and   the image shake correction is conducted in accordance with an electronic correction method that corrects a shake in an image by correcting a capture position of observation light for each pixel in the image sensor.   
     
     
         6 . The medical observation device according to  claim 1 , wherein
 the image shake correction is conducted in accordance with an optical correction method with a lens shift technique that corrects a shake in an image by moving a position of an optical system that guides observation light in the observation unit.   
     
     
         7 . The medical observation device according to  claim 1 , wherein
 the observation unit includes an imaging unit that generates an image by sensing observation light with an image sensor, and   the image shake correction is conducted in accordance with an optical correction method with an imager shift technique that corrects a shake in an image by moving a position of the image sensor.   
     
     
         8 . The medical observation device according to  claim 1 , wherein
 on a housing of the observation unit, a grip unit gripped by a user when moving the observation unit is provided.   
     
     
         9 . The medical observation device according to  claim 1 , wherein
 the support unit includes rotation axis units, and   each of the rotation axis units is provided with a vibration suppression mechanism that suppresses vibration in the rotation axis unit.   
     
     
         10 . The medical observation device according to  claim 1 , wherein
 the observation unit includes an endoscope, and a camera head connected to a base end of the endoscope and provided with an imaging unit that generates an image by sensing observation light internally with an image sensor, and   the medical observation device is an endoscopic device in which the camera head is supported by the support unit.   
     
     
         11 . A medical observation system, comprising:
 a medical observation device including an imaging unit that captures an image of a surgical site, a vibration sensor that detects a vibration of the imaging unit, a support unit that supports the imaging unit, and a control unit that conducts an image shake correction that corrects a shake in an image captured by the imaging unit, based on a detection value from the vibration sensor; and   a display device that displays an image subjected to the image shake correction by the medical observation device.   
     
     
         12 . An image shake correction method conducted in a medical observation device that includes an observation unit configured to perform magnified observation of a surgical site, a vibration sensor that detects a vibration of the observation unit, and a support unit that supports the observation unit, the image shake correction method comprising:
