Drive current variations are small or constant, to lock focusing, improve the clarity of human face region shooting, solve existing skill
The problem that the portrait photographs that art is shot in personage's movement or camera shake are smudgy.The embodiment of the present invention also provides
Corresponding device, which will be described in detail below.
Fig. 1 shows the implementation process of the method for focusing provided in an embodiment of the present invention of taking pictures.
In embodiments of the present invention, the method for the focusing of taking pictures be applied to smart machine, the smart machine include but
It is not limited to smart phone, tablet computer, learning machine, digital camera/video camera etc..The smart machine have camera function and
Face datection function.
Refering to fig. 1, the method for the focusing of taking pictures includes:
In step s101, setting human face region is in the ratio in the preview window and the corresponding pass between motor drive current
System.
Herein, ratio of the human face region in the preview window refers to the face that human face region occupies in the preview window
Product ratio.
The size of the motor drive current determines the mobile target position of camera lens.In embodiments of the present invention,
The motor drive current is the current value of the human face region shape library under corresponding ratio, i.e., under the motor drive current
The position that camera lens are moved to is the position of human face region shape library.Further, camera lens are driven according to motor
Characteristic, in the corresponding relationship, ratio of the human face region in the preview window is bigger, i.e., human face region is close shot, and motor drives
Streaming current is smaller；Ratio of the human face region in the preview window is smaller, i.e., human face region is distant view, and motor drive current is bigger.
The corresponding relationship can be stored by way of mapping table or corresponding relation database, herein with no restriction.
In step s 102, during taking pictures, obtain the preview window in human face region and its in the preview window
Ratio.
In step s 103, corresponding motor drive current is obtained according to the ratio, inputs the motor to motor and drives
Streaming current, to complete the focusing to human face region.
Illustratively, the area ratio can be indicated by pixel ratio, i.e., the human face region number of pixels that includes with
The ratio of total number of pixels in the preview window.When the ratio is the area ratio calculated based on pixel, the step
S102 can be with are as follows: smart machine is after starting camera, human face region in real-time detection the preview window, and obtains the face area
The number of pixels that domain includes；Then the total number of pixels of described the preview window is obtained；Calculate the number of pixels of the human face region
Ratio between the total number of pixels of the preview window obtains ratio of the human face region in the preview window.The ratio
Reflect the depth of view information of human face region.According to the ratio, lookup and institute from step S101 pre-set corresponding relationship
The corresponding motor drive current of ratio is stated, and with the motor drive current drive motor, to drive camera lens to be moved to target position
It sets, realizes the focusing to human face region.When personage is mobile or camera shake, if ratio of the human face region in the preview window
Change small, motor drive current variation is small or constant, to lock focusing, improve human face region shoot it is clear
Clear degree, the portrait photographs for solving the problems, such as that the prior art is shot in personage's movement or camera shake are smudgy.
As another preferred embodiment of the invention, the embodiment of the present invention, can be according to experiment when corresponding relationship is arranged
It counts obtained preset threshold and proportional region of the human face region in the preview window is divided into several segments, be then arranged each
The corresponding motor drive current of section.Fig. 2 shows another embodiment of the present invention provides focusing of taking pictures method implementation process.
Referring to Fig.2, the described method includes:
In step s 201, proportional region of the human face region in the preview window is divided into according to preset threshold several
Section.
In step S202, the corresponding motor drive current of each section of proportional region of setting.
When carrying out correspondence setting, the embodiment of the present invention counts ratio model of the human face region in the preview window first
It encloses.Illustratively, when human face region is not present in the preview window, the ratio is minimum value a；When human face region occupies entirely
When the preview window, the ratio is maximum value b.At this point, proportional region of the human face region in the preview window can be set
For [a, b].The number of the preset threshold can be arranged according to actual demand.Illustratively, when including two preset thresholds
When, i.e. the first preset threshold and the second preset threshold, first preset threshold are greater than second preset threshold, then step walks
Proportional region of the human face region in the preview window is divided into several segments according to preset threshold by rapid S201 specifically:
Proportional region of the human face region in the preview window is drawn according to first preset threshold and the second preset threshold
It is divided into three sections, wherein ratio maximum value of the human face region in the preview window to first preset threshold is the first ratio model
It encloses, first preset threshold to second preset threshold is the second proportional region, second preset threshold to the people
Ratio minimum value of the face region in the preview window is third proportional region.
Then corresponding motor drive current is arranged according to each section of proportional region.The motor drive current is for correspondence
Each ratio value in proportional region is applicable in, so that when personage's movement or camera shake generate micro-displacement,
The motor drive current variation remains unchanged, and then locks focusing, improves the clarity of human face region shooting, solves existing
The problem that the portrait photographs for having technology to shoot in personage's movement or camera shake are smudgy.
In step S203, during taking pictures, obtain the preview window in human face region and its in the preview window
Ratio.
In step S204, corresponding motor drive current is obtained according to the ratio, the motor is inputted to motor and drives
Streaming current, to complete the focusing to human face region.
Herein, described step S203, S204 are identical as Fig. 1 step S102, S103 as described in the examples, please specifically join
See the narration of above-described embodiment, details are not described herein again.
In conclusion ratio and motor drive current of the embodiment of the present invention by setting human face region in the preview window
Between corresponding relationship；During taking pictures, then by the human face region in acquisition the preview window and its in the preview window
Ratio, obtains motor drive current corresponding with the ratio, the motor drive current is input to motor, with drive motor
It drives camera lens mobile, completes the focusing to human face region.The motor drive current is that the ratio human face region is clear
The motor drive current of focusing.When personage is mobile or camera shake, if ratio variation of the human face region in the preview window
Small, the motor drive current variation is small or constant, to lock focusing, improves the clear of human face region shooting
Degree, the portrait photographs for solving the problems, such as that the prior art is shot in personage's movement or camera shake are smudgy.
