Abstract: An auto focus method for an image capturing device with a PD image sensor, comprising: (a) receiving pixel values of a sensing image sensed by the PD image sensor; (b) dividing the sensing image into a plurality of image blocks; (c) computing first cost values of each of the image blocks; (d) determining disparities of each of the image blocks according to the first cost values with in a specific range of each of the image blocks; (e) finding at least one object in the sensing image according to the disparities; and (f) setting a focus location of the image capturing device according at least one object location of the object.
