Embodiment Construction

[0064] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0065]The focus method, device and electronic equipment according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0066] Since the detection angle of the laser focus detection module is mostly fixed, the detectable area of ​​the laser focus detection module is also fixed. distance and cannot focus accurately. Moreover, when the detection angle of the laser focusing module changes, the distance returned by the object on the same focal plane will also change, and the accur...

Abstract

The present invention proposes a focusing method, device, and electronic equipment, wherein the focusing method includes the following steps: when receiving a focusing instruction, judging whether the focusing target is located outside the current detection area of ​​the laser focusing module; if so, controlling The laser focus module rotates so that the detection area of ​​the laser focus module covers the focus target; determine the rotation angle of the laser focus module, and obtain the distance between the focus target and the laser focus module through the laser focus module; determine the focus distance according to the rotation angle and distance , and focus according to the focusing distance. The embodiment of the present invention realizes the detection and focusing of the target outside the detection area, overcomes the defects of the current center focusing, can greatly expand the focus range, improve the clarity of the captured image, meet the different needs of users, and improve User shooting experience.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a focusing method, device and electronic equipment. Background technique [0002] With the rapid development of electronic technology and image processing technology, the camera function of terminals is becoming more and more powerful. During the shooting process, in order to take better and clearer photos, it is necessary to focus, that is, to adjust the position of the lens according to the current scene to obtain the highest definition photos. At present, in practical applications, the laser focus in the terminal can only satisfy the function of center focus, that is, it can only detect and focus on the focus distance corresponding to the object within the center range directly facing the laser focus module. However, if the depth of field of objects outside the center range is different from that in the center range, the above focus distance is not suitable for o...
