Original Abstract Submitted
Stabilizing camera preview frames involves obtaining preview frames and associated camera motion signals, smoothing out the trajectory of these frames to correct for camera movement, and then displaying the corrected frames. The process includes comparing current and prior preview frames and their motion signals to calculate smoothed trajectories and apply appropriate rotation and translation corrections. The specifics of trajectory smoothing take into account factors such as motion state, lighting, or capture mode, which can influence the strength of the smoothing parameter. Transform matrices are utilized based on correction rotation to adjust sample points within images, and special considerations like camera sag are factored into the image corrections.
