Abstract
In some embodiments, a plurality of images is captured through an image sensor of a camera during a period of time. The plurality of images is registered to calculate an image-sensor-based measure of movement of the camera during the period of time. The image-sensor-based measure of movement is compared to a motion-sensor-based measure of movement of the camera during the period of time, and a systematic offset between the motion-sensor-based measure of movement and the image-sensor-based measure of movement is calculated.
