  • Microscopy system and recording method for visualizing fluorescence
    Patent number: 7369073
    Abstract: An image sensor and a circuitry associated with the image sensor is used for recording a series of fluorescence images. The image sensor comprises a plurality of pixels for accumulating charges generated by incident radiation, and the circuitry converts the charges accumulated in the pixels into binary numbers. A gain of the circuitry is adjustable. The gain is set to a suitable maximum value at the beginning of a recording procedure. The gain is reduced if it is determined during the recording procedure that one or more brightness values of the recorded image exceed a suitably chosen maximum brightness value.
    Type: Grant
