1. A method to stabilize image capture for a camera device, comprising:
capturing, at an auxiliary frame rate and using an auxiliary imaging element rigidly coupled with the camera device, a plurality of auxiliary images of a light source attached to an object, wherein the auxiliary frame rate exceeds a camera frame rate of the image capture;
detecting each of a plurality of locations of the light source in a corresponding one of the plurality of auxiliary images;
analyzing, by a hardware processor, the plurality of locations to generate a measure of uncontrolled movement; and
adjusting, based at least on the measure of uncontrolled movement, the camera device during the image capture of the object by the camera device at the camera frame rate.
