Abstract: An exemplary image stabilizer includes a shaking sensor, a control module, a driving module, an image module, and a data adjusting module. The shaking sensor detects a shake of a lens associated with the image stabilizer. The control module stores a shake correcting setting having one or more error ranges. The driving module is controlled by the control module to move the lens according to the shake correcting setting. The image module captures an image through the corrected lens. The data adjusting module adjusts the shake correcting setting within one or more of the error ranges when a resolution value of the captured image is lower than a preset reference value.
