An optical viewing system () for viewing an object region has a display unit () which has a plurality of controllable display segments which make available color pulse sequences in order to generate a display image which is built up of a plurality of image points. The optical viewing system () includes a superposition unit () which superposes an image, which is made available by the display unit (), onto the image of an object region (). The optical viewing system has a camera unit () to which the superposed image of display unit () and object region () is supplied. The camera unit () has image sensors () whose light sensitivity is adjustable as a function of time. The light sensitivity of the image sensors () is matched to the color pulse sequence in such a manner that the image sensor () can detect at least two light pulses of different color from the color pulse sequence from a display segment.

Optical viewing system and method for operating the same

A surgical microscope () includes a viewing unit () for viewing an object () and an image projection module () for inputting image data () into the viewing unit (). The image projection module () includes a plano-convex lens and a plano-concave lens. The image projection module () includes an image display unit ().

In a process for the display of three-dimensional video images, in which at least two associated stereoscopic left-hand and right-hand partial images are electro-optically sensed at a given read-in frequency and the partial images are then sequentially reproduced on a display, the sensing of the two partial images takes place with a constant delay time with respect to each other, so that a delay which remains constant is ensured between the image formation in the camera and the reproduction of the partial image.
