Abstract
A scene is recorded simultaneously by two optical channels having different fields of view and different magnifications, whereby a picture detail from the narrow field of view is mixed into the image of the overall scene and the mixed image is portrayed on a single image portrayal device. The picture detail can follow the relative motion of an object on the basis of a tracking event. Higher detail recognition is provided for one person operation at a higher range without loss of the overall portrayal.
