Description

A kind of the focusing triggering method and system of intelligent selection focal modes
Technical field
The present invention relates to focusing technical fields, the focusing triggering method of especially a kind of intelligent selection focal modes and its answer With the system of this method.
Background technology
Due to the convenience of mobile phone, the Main way that mobile phone shooting solves is that simple and quick effectively obtain clearly is schemed Picture can not be set up due to the frivolous design of mobile terminal as professional half mm professional camera special manually controlling motor Mechanical Moving is focused Device.What the focusing overwhelming majority in mobile device used is all automated manner, and the microdevices such as focusing motor are in image procossing Complete focusing under the control of device, the focusing triggered manually be also finally inside machine completed by this mechanism, and for For family, without really going adjustment focus point manually, and before image processor processing focusing, need that there are a variety of triggerings Mechanism and software and hardware testing mechanism ensure that the focusing motor executed automatically can accurately move focusing position, also more and more at present Novel focusing mode appears in mobile terminal and completes focus operation faster more accurately to help user to screen, but focal modes Between be mutual exclusion, execute next time focus when need first to cancel before focusing, if these focal modes are concurrently focused, meeting So that the appearance for the problems such as focusing triggering is frequent and focusing is inaccurate, the intelligence for needing a set of perfect management focal modes to switch It can administrative mechanism.
Invention content
The present invention to solve the above problems, provide a kind of the focusing triggering method and system of intelligent selection focal modes, By the way that the weight between different focus pattern is arranged, intelligent selection focal modes are realized to trigger focusing.
To achieve the above object, the technical solution adopted by the present invention is:
A kind of focusing triggering method of intelligent selection focal modes, which is characterized in that include the following steps:
A. the weight and the corresponding focusing detection machine of each focal modes of each focal modes of setting camera terminal System;
B. focusing detection is executed respectively according to the corresponding focusing testing mechanism of each focal modes;
C. judge whether to need to trigger corresponding focal modes respectively according to the testing result of each focusing testing mechanism, if It is that focusing is submitted to apply, focusing is not otherwise submitted to apply;
D. the focusing application of submission is audited according to the weight of each focal modes, it is highest right with weight Coke applies for current focal modes and executes focusing, and stops focusing application of the weight less than the current focal modes and focusing inspection It surveys;
It e., will if there is focal modes more higher than the weight of current focal modes to propose focusing application in focus process The higher focal modes of the weight execute focusing as new current focal modes, and stop weight less than the new current focusing The focusing application and focusing detection of pattern;
F. after the completion of focusing, the focusing detection of the focal modes lower than the weight of current focal modes is reawaked, and is returned Return step b.
Preferably, the focal modes include it is below two or more:Contrast focusing, phase focusing, laser Focusing, ultrasonic wave focusing, and the contrast focusing further comprises manual focus, face auto-focusing, continuous auto-focusing.
Preferably, in the focus process of current focal modes, weight is higher than other focal modes roots of current focal modes Focusing detection is continued to execute according to respective focusing testing mechanism if testing result is to need to trigger corresponding focal modes to stop The only focusing of current focal modes, and enter weight and focused again higher than other focal modes of current focal modes.
In addition, the present invention also provides a kind of focusings of intelligent selection focal modes to trigger system, which is characterized in that it is wrapped It includes:
Weight setting module, the weight and each focal modes pair of each focal modes for camera terminal to be arranged The focusing testing mechanism answered;
Focusing detection module, for executing focusing inspection respectively according to the corresponding focusing testing mechanism of each focal modes It surveys;
Focusing judgment module, for judging whether to need triggering pair respectively according to the testing result of each focusing testing mechanism Otherwise the focal modes answered do not submit focusing to apply if focusing is then submitted to apply;
Weight judgment module, for being examined the focusing application of submission according to the weight of each focal modes Core applies for current focal modes with the highest focusing of weight and executes focusing, and stops weight and be less than the current focal modes Focusing application and focusing detection;
Focusing execution module, for executing focusing;
Wherein, in focus process, if there is focal modes more higher than the weight of current focal modes to propose focusing application, Then executes focusing using the higher focal modes of the weight as new current focal modes, and stops weight and be less than newly current The focusing application and focusing detection of focal modes, and after the completion of focusing, reawake lower than the weight of current focal modes The focusing of focal modes detects.
The beneficial effects of the invention are as follows:
The focusing triggering method and system of a kind of intelligent selection focal modes of the present invention, by the way that camera terminal is arranged The weight of each focal modes and the corresponding focusing testing mechanism of each focal modes, then respectively according to each focal modes Corresponding focusing testing mechanism execute respectively focusing detection, and according to it is each focusing testing mechanism testing result judge respectively be It is no to need to trigger corresponding focal modes, if focusing is then submitted to apply, focusing is not otherwise submitted to apply, according to described each The weight of focal modes audits the focusing application of submission, applies for current focal modes with the highest focusing of weight and holds Row focusing, and stop focusing application of the weight less than the current focal modes and focusing detection, in focus process, if having than current The higher focal modes of weight of focal modes propose focusing application, then using the higher focal modes of the weight as newly current Focal modes execute focusing, and stop focusing application of the weight less than the new current focal modes and focusing detection, finally, right After the completion of coke, the focusing detection of the focal modes lower than the weight of current focal modes is reawaked;So according to different focus The weight order of pattern carries out triggering focusing, realizes intelligence orderly selection focusing, to reach the variation or bat that adapt to shooting condition The variation for taking the photograph object prevents autofocus mode diversification and generates interference mutually, keeps focusing more stable, and in focus process Stop focusing application of the weight less than the current focal modes and focusing detection, to save system resource.
