Classification: CPC G  H | IPC G  H

Claim 0:
1. A method for automatically locating at least one target marker, comprising:
emission of radiation by the target marker, wherein by means of modulation, the radiation recurrently has a characteristic signature;
recording a first image sequence with a first frame rate;
statistically evaluating the first image sequence by reference to the signature with determination of a quality function, wherein the value of the quality function specifies a probability that target marker radiation is detected in a respective pixel;
identifying pixels with which target marker radiation is likely detected, based on the associated value of the quality function;
recording a second image sequence with a second frame rate, different from the first frame rate;
evaluating intensity signals of the second image sequence for said identified pixels; and
identifying the target marker radiation using the intensity signals on the basis of the signature.
