VIDEO BASED MICROSCOPE ADJUSTMENT

The present disclosure relates to an optical observation device which is controlled in a sterility preserving manner, and to a corresponding controlling program and/or program storage medium. The optical observation device includes a main structure having at least one optical camera, a support structure adapted to variably position the main structure, and a control unit that receives a sequence of images from the at least one optical camera, searches a current image from the sequence of images for a trackable object, tracks the trackable object shown in the sequence of images subsequent to the current image; and controls adjustable properties of AR-content superimposed with the sequence of images in accordance with a motion of the trackable object, wherein the adjustable properties of the AR-content include a location, orientation, and/or size of the AR-content with respect to the sequence of images.
