METHOD AND SYSTEM FOR IMAGE STABILIZATION

摘要

In a method for image stabilization a number of operations are performed to stabilize an image and to output a focal length value. The steps include capturing video by means of a video camera with unknown focal length running an image stabilization process operating on an input from a hardware detector detecting the displacement of the camera and on an adjustable focal length value. Inter-image displacement is corrected based on the input from the hardware detector and the adjustable focal length value. By evaluating the displacement and adjusting the focal length value until a satisfactory image stabilization is achieved a value of the focal length may be output.
