Techniques described herein provide a method for improved image and video stabilization using inertial sensors. Gyroscopes, accelerometers and magnetometers are examples of such inertial sensors. The movement of the camera causes shifts in the image captured. Image processing techniques may be used to track the shift in the image on a frame-by-frame basis. The movement of the camera may be tracked using inertial sensors. By calculating the degree of similarity between the image shift as predicted by image processing techniques with shift of the device estimated using one or more inertial sensor, the device may estimate the portions of the image that are stationary and those that are moving. Stationary portions of the image may be used to transform and align the images. For video stabilization, the realigned images may be combined to generate the video. For image stabilization, the realigned images may be either added or averaged to generate the de-blurred image.
