If Apple's patent filing with the United States Patent & Trademark Office (USPTO) is anything to go by, future iOS devices could appeal further to iPhoneography fans by allowing them to take very detailed snaps using a fancily named 'super-resolution' imaging.
According to the filing, this could be achieved by using optical image stabilization - a feature that must be implemented in the camera hardware itself - to capture multiple images in a burst, each at a slightly offset angle.
The software would take it from there and stitch individual image data together to form a single super-resolution image, bypassing the need for more megapixels...
