Abstract: An image capturing device includes a lens, a lens driver configured to change a focus position by moving the lens, an image sensor configured to detect light passed through the lens, and a focus controller configured to control, based on an image generated by the image sensor, the lens driver to adjust the focus position. The focus controller is further configured to: monitor a feature change of a saturated object having an intensity greater than or equal to a threshold value, in each of a plurality of regions of an image, by adjusting the focus position; and adjust the focus position based on a trend of the feature change of the saturated object while the focus position is changed in a direction.
