Abstract
An electronic imaging device that is focused by capturing data samples from a region of at least one photodetector while changing focus settings and analyzing the data samples to identify an optimum focus setting. The size of the regions from which the data samples are captured is reduced during focusing to reduce the amount of data to be processed.
