1. A non-transitory program storage device, readable by a processor and comprising instructions stored thereon to cause the processor to: obtain a first image from an image capture device at a first time, the first image having a first motion data from a motion sensor of the image capture device; obtain a second image from the image capture device at a second time, the second image having a second motion data from the motion sensor and a focal length; determine a rotation metric indicative of the rotation of the image capture device between the first time and the second time based on the first motion data and the second motion data; determine a translation measure for the second image, relative to the first image, based on the rotation metric and the focal length; and align at least a portion of the second image with at least a portion of the first image in a memory based on the translation measure without performing an image registration that uses image processing operations on the first image and the second image.
