Abstract:
1. A method of capturing images, the method comprising: implementing a zoom in operation in response to user control, said zoom in operation including adjusting a direction of a first light redirection device of a first optical chain of a camera device, said first light redirection device being one of a substantially plane mirror or a prism, said adjusting increasing an overlap in scene areas captured by the first optical chain of said camera device and a second optical chain of said camera device and adjusting a direction of a second light redirection device of said second optical chain, said second light redirection device being a second mirror or a second prism, said adjusting of said second light redirection device increasing the overlap in scene areas captured by the first and second optical chain; wherein said first and second optical chains have the same focal length f1, and wherein said zoom in operation corresponds to a zoom focal length setting in the range of f2 to f1, said range including f2 and f1, capturing an image of a scene area using the first optical chain; capturing an image of the scene area using the second optical chain; capturing an image of the scene area using a third optical chain of said camera having a focal length f2, where f2 is smaller than f1; and generating a composite image, in accordance with a zoom focal length setting, from images captured by said first, second and third optical chains, wherein generating the composite image includes performing a crop operation on the image captured by the third optical chain when said zoom focal length setting is greater than f2.
