Abstract
Methods, software, and apparatus for focusing an image in biological instrument are disclosed. Focusing elements are moved to various focus positions within a focus element travel range, and sample images are captured at the various focus positions. The sample images are resolved into subregions and an optimal focus position is determined based on the image intensity statistical dispersions within the identified subregions.
