Abstract
An autofocus method includes receiving a left image having a first blurriness value and a right image having a second blurriness value, filtering the left image so that the first blurriness value becomes the same as the second blurriness value, and generating a control signal for controlling the lens module based on a difference between a third blurriness value of a filtered left image and the second blurriness value.
