Medical visualisation system and method for video stabilisation in such a system

A method for video stabilization in a medical visualization system, in particular a surgical microscope, comprising an image sensor, wherein the method includes the following steps:

• a) providing the medical visualization system and a movement detecting device that detects a movement of the image sensor and generates corresponding sensor movement data,
• b) capturing an object field and generating video data of the object field by means of the image sensor and generating image movement data by evaluating the video data, and
• c) correcting the video data, comprising
• c1) calculating displacement vector data that only or to a proportion of at least 60% reproduce a movement of the image sensor, but do not, or only to a proportion of at most 40%, reproduce a movement within the object field, with the combined use of the sensor movement data and the image movement data, wherein the image movement data which reproduce movement changes in the object field are weighted and/or filtered on the basis of the sensor movement data, and
• c2) correcting the video data by means of the displacement vector data,
• wherein a movement vector range is defined on the basis of the sensor movement data and only image movement data which lie within this range are used for the calculation of the displacement vector data.
