METHODS AND APPARATUS FOR SUPPORTING ZOOM OPERATIONS

摘要

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.

主权项

1. A method of capturing at least one image, the method comprising;
moving a first light redirection device, said first light redirection device being one or 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; and 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.
