Beschreibung
Zusammenfassung:	The present invention provides a method and an apparatus for focusing, applied in image processing field, enabling a terminal in an automatic focusing process not to suspend automatic focus function. The method includes: determining an imaging mode switched from a first picture taking device in a first imaging mode to the first picture taking device or a second picture taking device in a second imaging mode, estimating a second position of the target object in the second imaging mode according to a first position of a target object in the first imaging mode and a principle of epipolar geometry, and searching for the target object in the second imaging mode according to the estimated second position of the target object in the second imaging mode.
