Methods and apparatus for supporting zoom operations
First Claim
1. A method of using a camera device, the method comprising;
- moving a first light redirection device, said first light redirection device being one of a substantially plane mirror or a prism, of a first optical chain of the camera device to a first position in accordance with an indicated zoom setting;
capturing a first image of a first portion of a scene area of interest using said first optical chain while said first light redirection device is at said first position; and
capturing, using a second optical chain of said camera device, a second image of a second portion of a scene area of interest, said second image being captured while said first light redirection device is at said first position, said first and second optical chains having different focal lengths.

Abstract
Methods and apparatus for performing a zoom operation are described using multiple optical chains in a camera device. At least one optical chain in the camera device includes a moveable light redirection device, said light redirection device being one of a substantially plane mirror or a prism. The moveable light redirection device is moved to a position in accordance with a zoom setting, and a portion of a scene area of interest in captured. Different discrete zoom setting values correspond to different positions of the moveable light redirection device resulting in different capture areas. In some embodiments, multiple optical chains with moveable light redirection devices are used to capture different portions of a scene of interest. A composite image is generated from a plurality of captured images corresponding to different optical chains. A higher zoom setting corresponds to more overlap between captured images of different optical chains.

16. A non-transitory machine readable medium including machine executable instructions which when executed by a processor of a camera device control said camera device to:
-
move a first light redirection device, said first light redirection device being one of a substantially plane mirror or a prism, of a first optical chain of a camera device to a first position in accordance with an indicated zoom setting; capture a first image of a first portion of a scene area of interest using said first optical chain while said first light redirection device is at said first position; and capture, using a second optical chain of said camera device, a second image of a second portion of a scene area of interest, said second image being captured while said first light redirection device is at said first position, said first and second optical chains having different focal lengths.
