Abstract

An optical observation apparatus has an optical image channel for viewing optical field-of-view images, a processing unit to generate a first electronic insertion image via a first electronic image channel, and a data insertion image projector for generating an optical insertion image from the first electronic insertion image and inserting that image into the optical field-of-view image. An acquisition device acquires the optical field-of-view image without the optical insertion image inserted by the data insertion image projector. A second electronic image channel has a superimposition module, that superimposes the electronic field-of-view image with an electronic insertion image and provides the superimposed images via the second electronic image channel. The processing unit generates a second electronic insertion image, provides available display data elements, and makes it possible to assemble the electronic insertion images and assign them to different electronic image channels.
