1. An imaging apparatus housed at least partially within a mobile device housing, and configured for multiple image acquisition modes, the imaging apparatus comprising: an image sensor comprising an imaging surface; a first optical assembly positioned over a first image capture region of the imaging surface, and defining a first field of view, wherein the first optical assembly images onto the first image capture region, any object plane within the first field of view; and a second optical assembly positioned over a second image capture region of the imaging surface, and defining a second field of view, wherein the second optical assembly images onto the second image capture region, any object plane within the second field of view; a controller configured to: process image data from pixels within the first image capture region responsive to triggering of a first image capture mode; and process image data from pixels within the second image capture region responsive to triggering of a second image capture mode.
