Abstract
Methods and apparatus for processing images captured by a camera device including multiple optical chains, e.g., camera modules, are described. Three, 4, 5 or more optical chains maybe used. Different optical chains capture different images due to different perspectives. Multiple images, e.g., corresponding to different perspectives, are captured during a time period and are combined to generate a composite image. In some embodiments one of the captured images or a synthesized image is used as a reference image during composite image generation. The image used as the reference image is selected to keep the perspective of sequentially generated composite images consistent despite unintentional came movement and/or in accordance with an expected path of travel. Thus, which camera module provides the reference image may vary over time taking into consideration unintended camera movement. Composite image generation may be performed external to the camera device or in the camera device.
