1. A method comprising: determining a scene to be captured at a first resolution, wherein the scene to be captured is within a field of view of an image sensor; causing capture by the image sensor of a plurality of sub-images using off-center optical zooming and cropping at a respective second resolution, the second resolution being less than the first resolution, wherein the plurality of sub-images depicts a portion of the scene to be captured; and using the plurality of sub-images to generate an output image depicting the scene to be captured at the first resolution; wherein the image sensor is capable of capturing an image at the first resolution, but an output resolution of the image sensor is constrained by hardware limitations to a third resolution that is less than the first resolution, and wherein the second resolution comprises a resolution less than or equal to the third resolution.
