Abstract
Described is an apparatus, including computer program products, for adjusting the focus of an image capturing device. An apparatus for capturing a focused digital image of a scene includes a lens having an optical surface including a deformation that is asymmetric with respect to an optical axis of the lens, and an aperture component configured to adjust a position of the aperture stop of the lens on a plane that is substantially perpendicular to the optical axis of the lens. The apparatus includes an image sensor configured to capture a digital image of an optical image formed by the lens, the digital image being defocused based on the position of the aperture stop. The apparatus includes a digital image processor configured to generate a focused digital image based on the digital image captured by the image sensor.
