Abstract: Real-time performance in image recognition is improved, and a deterioration in robustness is inhibited. A medical observation system according to an embodiment includes: a first imaging unit (11) that includes a plurality of pixels (110) each of which detects a change in luminance of incident light as an event and that acquires an image of an environment in an abdominal cavity of a living body; a polarizing filter (15) disposed on an optical path of the incident light incident on the first imaging unit; and an adjustment unit (20) that adjusts luminance of the incident light incident on the first imaging unit by adjusting luminance of light transmitted through the polarizing filter based on the image acquired by the first imaging unit.

Abstract: The present disclosure relates to a medical observation system, an image processing method, and a program capable of providing image display more helpful for a surgeon. A correction processing unit performs correction processing on a wide-angle image which is a captured image of a medical treatment target, a clipping processing unit moves a clipping area for a display image clipped from the wide-angle image, and a correction control unit controls the correction processing according to a relative state of the clipping area to the wide-angle image. The present disclosure can be applied to, for example, an endoscopic surgery system.
