Abstract: Digital image stabilization (DIS) may be implemented in image capture devices to address some or all above problems of local stabilization and in-frame distortions alone or in combination with electronic image stabilization (EIS) to reduce artifacts, shake leftovers, and other problems resulting from insufficient global stabilization. DIS may use image sensor motion data derived from image-based information, such as motion vectors between frames, to modify captured image data to generate corrected image frames having improved global stabilization and reduced distortion artifacts and shake leftovers resulting from camera motion. The image sensor motion data may be used in combination with non-image sensor motion data, such as data from a gyroscope an optical image stabilization (OIS) device, a magnetometer, an accelerometer, and/or auto-focus (AF) feedback to perform image stabilization. Image sensor motion data may be used to determine a translation (e.g., a three-dimensional displacement) motion of the image capture device.
