FIELD: physics, photography.
SUBSTANCE: invention relates to predictive autofocusing. Provided is a method for autofocusing in an imaging device having an objective lens and a stage for holding a sample to be imaged. The method includes determining a measured focal distance corresponding to at least a first of a plurality of logical image segments. The method also includes imaging the first logical image segment using the measured focal distance. The method also includes determining a predicted focal distance for a second of the plurality of logical image segments using the measured focal distance and a stored focal distance variation parameter. In addition, the method includes imaging the second logical image segment using the predicted focal distance.
EFFECT: faster scanning, high image quality and simple sequence of clinical operations when scanning.
