An optical observation instrument according to the invention, in particular a surgical microscope or exoscope, comprises an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path for recording a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement. The instrument moreover comprises a retaining apparatus, on which the optics unit is mounted so as to be rotatable about a first axis of rotation, the latter at least approximately corresponding to an axis of the objective arrangement, wherein the optical observation instrument has a viewing direction that is angled in relation to the axis of the objective arrangement and comprises a deflection element, arranged on the object-side of the objective arrangement, for deflecting the first and the second beam path into the objective arrangement. The invention further relates to a method for generating a stereo image of an object field.

An observation device is provided with an image acquisition unit comprising at least one image sensor, an image display unit, that is arranged for displaying image data that is provided by the image acquisition unit, an image processing unit for image processing procedures, and a control unit comprising a multi-axis input module. The image acquisition unit is configured to provide recorded images having a predefined recording pixel quantity. The image display unit is configured to display display images having a predefined display pixel quantity, wherein the recording pixel quantity is equal to or greater than the display pixel quantity. Image pixels of the display pixel quantity are obtained from the recording pixel quantity. Subsets of the recording pixel quantity are selected to form the display pixel quantity. Image acquisition parameters and display parameters are controlled by the input module. The input module is arranged to be coupled with the image acquisition unit for controlling at least one image acquisition parameter.

Observation device comprising a control unit

An optical observation system () according to the invention comprises an optical observation apparatus, more particularly an endoscope or an exoscope (), comprising an imaging optical unit and an electronic image recorder, wherein the imaging optical unit is embodied to image an object field () on the electronic image recorder with an alterable imaging scale and the electronic image recorder is embodied to produce recorded image data of the object field (), an image display apparatus for presenting at least a section of the object field () and an image processing apparatus (), which is configured to produce display image data by scaling the recorded image data with an alterable scaling factor and to actuate the image display apparatus with the display image data. According to the invention, the imaging scale is alterable over a plurality of levels and the scaling factor is continuously alterable, wherein the scaling factor is coupled to the optical imaging scale in such a way that the scaling factor is changed in the opposite sense when the optical imaging scale is altered. The invention also relates to a method for operating an optical observation system ().
