Abstract

An exposure control system for the photographic recording of a microscope image comprises a two dimensional photographic receiver arrangement for detecting the image brightness of the microscope image. The receiver arrangement is a component part of a camera system which is attachable to a standard camera part of a microscope. The receiver arrangement has an interface for transmitting image information of a microscopic object detected by the receiver arrangement to a viewing unit. A first input device is included to which the viewing unit is coupled for manual selection of at least one optical image region on the receiver arrangement. The intensity value of the image region forming a control signal for the exposure time of the photographic recording.
