Abstract
A method and apparatus for calibrating a position of an image sensor, and a method of detecting the position of an image sensor are provided. The method of calibrating the position of an image sensor includes: obtaining first image information corresponding to a first position of the image sensor and obtaining second image information corresponding to a second position of the image sensor, calculating cross-correlation values between the obtained first image information and second image information; determining whether or not the calculated cross-correlation values are symmetrical; setting a driving power value of the image sensor for moving the image sensor the distance between the first position to the second position as a reference driving power value for moving the image sensor one-pixel distance, if it is determined that the cross-correlation values are not symmetrical; and calibrating the position of the image sensor by using the set driving power value.
