Abstract
An apparatus, method, and computer readable medium related to autofocusing a camera lens system. An initial image is captured at a first lens position and focus information is extracted with respect to a first plurality of focus windows. A second image is captured at a second lens position and focus information is extracted for a second plurality of focus windows that correspond to the first plurality of focus windows in the initial image. The focus information for corresponding windows is compared to determine whether the focus status in each window is improving or degrading; this determination reveals whether the lens is positioned in a desirable position with respect to the data revealed by the data extracted from the focus windows.
