A method and an apparatus for focusing are provided. The method includes: determining that imaging mode switches from a third imaging mode to a fourth imaging mode, wherein the third imaging mode comprises a mode in which a non-depth camera is used to take a picture, and the fourth imaging mode comprises a mode in which a depth camera is used to take a picture; creating a third feature template, wherein the third feature template is used to record depth information of a target object; and searching for an image of the target object according to the third feature template in the fourth imaging mode.

Method and apparatus having a function of constant automatic focusing when exposure changes

A method and an apparatus for focusing are disclosed. The method includes: determining a switch of imaging mode from a first imaging mode to a second imaging mode, wherein a position of an image of a target object in the first imaging mode is different from a position of an image of the target object in the second imaging mode; estimating the position of the image of the target object in the second imaging mode according to a resolution in the first imaging mode, a resolution in the second imaging mode, a field of view in the first imaging mode, a field of view in the second imaging mode and the position of the image of the target object in the first imaging mode; and searching for the image of the target object in the second imaging mode according to the estimated position.

Method and apparatus for focusing

A method and an apparatus for focusing are provided. The method includes: determining a switch 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; and searching for the target object according to the second feature template in the second imaging mode.

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.

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.

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.
