ABSTRACT:
A method for automatic focus for an image capture device comprising a lens, the method comprising, for a first lens position, processing image data generated at a plurality of local focus positions of the lens in order to generate first metric data representing a focus measure for the first lens position, adjusting the lens position on the basis of the first metric data, and generating corresponding second metric data for at least one local focus position at the new lens position, and determining an estimated point of true focus for the lens on the basis of the first and second metric data.
