Abstract:
The present invention provides an image stabilization method and device applied to a mobile device. The method comprises: acquiring images captured by a pan/tilt camera of a mobile device at different times with respect to the same target; extracting image feature information from each of the acquired images; for each piece of image feature information, determining a first target image and a second target image, from among all of the acquired images, associated with the given image feature information, a capturing time of the first target image being prior to a capturing time of the second target image; and correcting, for each determined second target image, positions of pixels in a given second target image according to position information of the image feature information in the first target image and position information of the image feature information in the second target image. A trajectory of each piece of image feature information is acquired on the basis of a visual algorithm, and then positions of corresponding image pixels are corrected according to the trajectory of each piece of image feature information, so as to complete stabilization processing of an image.
