The present invention provides a method and an apparatus for focusing, applied in image processing field, which includes determining that imaging mode switches from a first imaging mode to a second imaging mode, making luminance adjustment to a first feature template of target object in the first imaging mode to obtain a second feature template, searching for an image of the target object according to the second feature template in the second imaging mode. The method enables a terminal in an automatic focusing process to realize a function of constant automatic focusing, and to make user interaction decreases and focus on the target object in time, accurately and efficiently to output constant satisfactory images or videos.
