A medical observation system (2, 3) is provided with: a light source (223) for illuminating an affected part of a body; a separation optical system (213) for splitting light from the affected part of the body into a plurality of polarized light beams, the polarization directions of the polarized light beams are different from each other; a detection unit (313), which detects a plurality of polarized light beams individually; a calculation unit (305), which individually calculates the speckle contrast based on the detection results of the plurality of polarized light beams; and a processing unit (303), which is based on the At least any one of the calculation results of the speckle contrast corresponding to the polarized light beams is performed, and the process of observing the affected part of the body is performed. |
