Abstract
Methods and apparatus relating to image capture of image portions using optical chains with different focal lengths are described. In some embodiments different portions of a scene area of interest captured by different optical chains operating in parallel are combined. The combining in some embodiments is performed using depth information generated from two images captured by two different optical chains which capture at least some common overlapping portions of the scene area of interest. The depth information maybe generated using an image of the entire scene and one or more other images of the scene or portions of the scene area of interest. The use of multiple optical chains in parallel facilitates generation of an image with a higher overall pixel count than would be possible using a single sensor of one of the optical chains and/or with more light capture than would be captured using a single optical chain.
