Abstract: An autofocus method determines that a ranging device of a digital camera has failed in an attempt to provide a distance estimation. The ranging device provides one or more parameters indicating conditions related to the failure of the ranging device to provide the distance estimation. An autofocus sequence based on the one or more parameters is then performed.

Abstract: A method of adjusting a lens may include adjusting the lens at a first focus position, and acquiring a first image of a scene through the lens. The method may further include adjusting the lens at a second focus position, and acquiring a second image of the same scene through the lens. In addition, the method may include producing respective power spectra of the first and second images, and producing a criterion representing the ratio of the power spectra to estimate a focus error of the lens.
