The invention relates to a surgical microscope (10) for producing an observation image of an object region (32) for an observing person. The surgical microscope (10) has an image-recording device (35) for recording an image of the object region (32), a display device (47), and an image-processing and control device (54), which is connected to the image-recording device (35) and to the display device (47) for the visualization of an image of the object region (32) recorded by means of the image-recording device (35). According to the invention, the surgical microscope (10) contains a computing unit (45) for providing object-region image data that are obtained in an imaging method and that can be fed to the display device (47) for display, which computing unit is connected to the image-processing and control device (54). In the surgical microscope (10), there is a switchable imaging optical unit (14), which feeds the observation image of the object region (32) to an eyepiece (22) by means of an optical observation beam path (28) in a first switching state, on which observation image of the object region the object-region image data displayed by means of the display device (47) can be superimposed in a positionally correct manner. In a further switching state different from the first switching state, the switchable imaging optical unit (14) interrupts the purely optical observation beam path (28) from the object region (32) to the eyepiece (22) in order to display in the eyepiece (22) an image of the object region (32) from the optical observation beam path (28), which image is recorded by means of the image-recording device (35) and displayed by means of the display device (47). |
