Zusammenfassung:	A method and an apparatus for focusing are disclosed. The apparatus includes: a determining module, configured to determine that an imaging mode switches from a first imaging mode to a second imaging mode; an image position estimating module, configured to estimate a position of an image of a target object on a picture taking device in the second imaging mode according to a position of an image of the target object on a picture taking device in the first imaging mode and a principle of epipolar geometry; and a searching module, configured to search for the image of the target object in the second imaging mode according to the estimated position of the image of the target object on the picture taking device in the second imaging mode.
