Abstract
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.
Claims11
A method for focusing, comprising:
- determining that imaging mode switched from a first imaging mode to a second imaging mode, wherein the first imaging mode and the second imaging mode have different exposures;
- making illumination adjustment to a first feature template of a target object in the first imaging mode according to first illumination information of the target object in the first imaging mode and second illumination information of the target object in the second imaging mode to obtain a second feature template;
- searching for the target object according to the second feature template in the second imaging mode.
