Abstract
A photomicroscope includes a port for a still camera (11) and an additional video camera (14). The video image of the video camera (14) serves both for the operation of a passive autofocusing system (23, 24) and for the determination of the exposure time for the still camera (11). The image areas that are used for exposure metering can be selected via a control panel (27). The integration time of the video camera (14) can be varied up to the range of minutes. The selected image areas are superimposed on the object image.
