Abstract:
An apparatus for compensating an auto-focus of an image capture device by utilizing a red-eye eliminating function, comprising:an image sensor for capturing an image of an object so as to determine a focal length evaluation value of the object; a focal length adjuster for adjusting a focal length of the image capture device; a red-eye eliminating device capable of flashing for providing a red-eye eliminating function; and an auto-focus module for preliminarily determining a distance from the object to the image capture device based on the focal length evaluation value of the object captured by the image sensor to drive the focal length adjuster for performing a rough adjustment of the focal length of the image capture device, and when the red-eye eliminating device flashes for eliminating a red-eye effect, further determining the distance from the object to the image capture device based on the focal length evaluation value of the object captured by the image sensor to drive the focal length adjuster, thereby performing a fine adjustment of the focal length of the image capture device, wherein the red-eye device flashes a plurality of times, and whenever the red-eye device flashes said plurality of times, the auto-focus module drives the focal length adjuster to perform a fine adjustment of the focal length of the image capture device for each flash.
