Patent ID: 7369073

Claim:
A microscopy system for visualizing a fluorescence, wherein the microscopy system comprises: an image sensor having a plurality of pixels for accumulating charges generated by incident radiation; microscopy optics having a first beam path for imaging an object region onto the pixels of the image sensor; circuitry for converting a charge amount accumulated in a group of pixels into binary numbers, wherein at least one gain of the conversion is adjustable such that each binary number represents a charge amount from within a range of charge amounts less than a charge amount limit dependent on the at least one gain; and a controller which is configured to adjusting the at least one gain such that the charge amount limit is a small first charge amount; and then repeatedly receiving binary numbers representing an image detected by the image sensor from the circuitry and adjusting the at least one gain such that the charge amount limit is greater than in the preceding adjusting of the at least one gain if at least one of the binary numbers representing the detected image represents a charge amount greater than the maximum value.
