Other portable devices of words, laptop computer or tablet computer etc.It is to be further understood that in some embodiments
In, the equipment is not portable communication device, but with camera and touch sensitive surface (for example, touch-screen display
And/or touch tablet) desktop computer.
In discussion below, the terminal for including display, camera and touch sensitive surface is described.It however, should
When understanding, one or more of the other physical User that terminal can include such as physical keyboard, mouse and/or control-rod connects
Jaws equipment.
Terminal supports various application programs, such as one or more of following：Drawing application program, demonstration application journey
Sequence, word-processing application, website create application program, disk imprinting application program, spreadsheet applications, game application
Program, telephony application, videoconference application, email application, instant messaging applications, exercise

Gray scale or so-called object brightness rank are appreciated in order to be realized in different lighting conditions and scene, so as to
So that the video or image of shooting (capture) were both less dark or less bright, when terminal needs to adjust lens opening, exposure sensor
Between, sensor analog gain and sensor/picture signal processing (Image Signal Processing, ISP) digital gain,
This process is known as automatic exposure (Automatic Exposure).Specifically, the main three kinds of Exposure modes of automatic exposure：Entirely certainly
Traverse formula exposes, aperture priority exposure and ShutterPriority Auto exposure.Wherein, in full-automatic formula Exposure mode, user is not required to
Shutter speed and f-number are adjusted manually, it is only necessary to good focus in the image preview interface of terminal, press shutter release
Button just, according to the exposure value of the picture shot measured by the photometric systems such as light sensor according to producer can give birth to by terminal
Set shutter and aperture exposure combination, are automatically set shutter speed and f-number during production.In aperture priority Exposure mode
In, user needs to adjust f-number manually, and then terminal can be according to the picture shot measured by the photometric systems such as light sensor
The exposure value in face is automatically set shutter speed.Since aperture is smaller, the depth of field is longer, therefore this mode is relatively specific for needing
Determine the photographed scene (such as landscape shooting, portrait) of the depth of field.In ShutterPriority Auto Exposure mode, user needs to adjust manually
Shutter speed, then terminal can automatically be set according to the exposure value of the picture shot measured by the photometric systems such as light sensor
Iris setting value.
Although automatic exposure has provided very big facility to the user in the shooting process of terminal so that user can facilitate
Ground takes the suitable video of brightness or image.But for very bright place existing in scene, and there is the very dark place this
The very big scene of light and shade contrast, automatic exposure are just difficult to take into account each place in scene, are easy to cause partial exposure excessively (mistake
Expose) or it is under-exposed (owing to expose).For example, when the deeper user of the colour of skin is in self-timer on daytime, it is excessively bright to be susceptible to human face region
Situation；When more people are in step with, the individual that differs greatly if there is the colour of skin (such as Black people white man takes pictures together), it is also difficult to take into account each
People is susceptible to the excessive lightness or darkness situation of part human face region.
To solve the above-mentioned problems, an embodiment of the present invention provides a kind of image pickup method, face is added in shooting process
Detection, and according to the exposure parameter of face complexion bright-dark degree adjusting terminal, can so that face's brightness is more suitable.Specifically
Ground, terminal add face complexion identification in shooting process.When having detected that complex scene occurs, according to preset method
Judge concrete scene, for concrete scene, terminal is respectively adopted different exposure parameters and is shot to obtain multiple shooting images,
Then the multiple shooting images obtained to shooting carry out synthesis processing, obtain the image that exposure takes into account the different colours of skin, different scenes.
Further specifically, after the shooting function for opening terminal in user, terminal can export normally in screen
Preview screen, while it is being exposed parameter setting from the background.During parameter setting is exposed, terminal is first with interior
The light sensor put obtains the environment bright angle value (i.e. ambient light data) of current environment (environment i.e. to be captured).According to acquisition
The environment bright angle value arrived and preset environment classification rule, terminal can determine the environmental form described in current environment.Its
In, the environment category can include but is not limited to outside room on daytime, in daytime room, half-light (night) etc..
Further, terminal can obtain the face complexion data in preview screen.According to the face complexion number got
According to this and preset skin color classification rule and colour of skin partition of the level rule, terminal can determine each face in preview screen
Colour of skin type and colour of skin rank.Wherein, the colour of skin type can include but is not limited to white, yellow, black etc..At one
In specific embodiment, the colour of skin rank can for example include 1 to 15 grades.Wherein, the 1st grade to the 5th grade of colour of skin rank pair
The colour of skin type answered is white, and the 6th grade to the 10th grade of the corresponding colour of skin type of colour of skin rank is yellow, the 11st grade to the 15th grade
The corresponding colour of skin type of colour of skin rank be black.
Further, current shooting may determine that according to the environmental form, colour of skin type and colour of skin rank, terminal that get
Whether scene is complex scene.It should be noted that photographed scene can distinguish simple scenario and complex scene.Wherein, for
Simple scenario does not have the king-sized place of light and shade difference in scene, is not in office when terminal is shot by automatic exposure
Portion's overexposure owes the situation exposed.For complex scene, existing very bright place in scene, and have very dark place, terminal passes through
It is easy to appear local overexposure or the deficient situations exposed when automatic exposure is shot.Specifically, when most skin lightening color in preview screen
When the colour of skin data difference of the most dark colour of skin reaches default value, terminal may determine that present filming scene is complex scene.
For example, if existing white man has Black people again in preview screen, then terminal may determine that present filming scene is complex scene.
Alternatively, when environmental form and colour of skin type meet the first preset relation, terminal may determine that present filming scene for complexity
Scene.Wherein, when environmental form is daytime, colour of skin type is black, alternatively, environmental form is half-light, colour of skin type is white
When, terminal can determine that environmental form and colour of skin type meet the first preset relation.
Further, when it is complex scene to judge present filming scene, terminal can be that present filming scene is set
Multigroup (at least two groups) exposure parameter.Specifically, terminal can be that the object with different colour of skin ranks sets different exposures
Parameter.For example, when there are one colour of skin type being the object of yellow and when a colour of skin type is the object of black in preview screen,
Terminal can be that two objects set two groups of different exposure parameters.Wherein, the exposure parameter can include but is not limited to expose
Between light time, f-number, shutter speed etc..Further, terminal can also be that current environment sets exposure parameter.Specifically,
When environmental form and colour of skin type meet the second preset relation, terminal can be that one group of exposure ginseng is separately provided in current environment
Number, this group of exposure parameter are different from any group of exposure parameter for object setting.Wherein, when environmental form be daytime, object
Colour of skin type be black, alternatively, when environmental form be half-light, when the colour of skin type of object is white, terminal can be true
Determine environmental form and colour of skin type meets the second preset relation.Specifically, when environmental form and colour of skin type are unsatisfactory for second in advance
If during relationship, terminal can be that current environment sets one group of exposure parameter, this group of exposure parameter and terminal are its of object setting
In one group of exposure parameter it is identical.For example, working as environmental form for daytime, there are two pairs that colour of skin type is yellow in preview screen
As, and during the colour of skin rank difference of described two objects, terminal can be colour of skin rank in current environment and described two objects
Higher object sets identical exposure parameter.
Further, under every group of exposure parameter of setting, terminal can quickly be shot respectively, obtain multiple shootings
Image.
Further, terminal can will shoot obtained multiple shooting images one image of synthesis.Specifically, according to object
Detection process, terminal can obtain background area and subject area (one or more) in shooting image, according to exposure parameter
With the relationship of object and environment, terminal can determine the interpolation weight in background area and each object region in each shooting image
Weight, and processing is overlapped to multiple shooting images according to the interpolation weights determined, obtain final target image.It is optional
Ground, terminal can also export in screen and store the target image.Below in conjunction with Fig. 1 to Fig. 5 to the embodiment of the present invention
The image pickup method and terminal of offer are specifically described respectively.
It is a kind of schematic flow diagram of image pickup method provided in an embodiment of the present invention referring firstly to Fig. 1.Specific implementation
In, each step that this method includes can be performed by terminal.Image pickup method as shown in Figure 1 can include：
S11, the ambient light data and object color data for obtaining environment to be captured.
In a specific embodiment, terminal can obtain the environment of environment to be captured by built-in light sensor
Light data.Wherein, the ambient light data for example can be ambient brightness value.
It should be noted that the described object of the embodiment of the present invention refers specifically to human body.In a specific implementation
In example, the object color data can be specially object colour of skin data.In the specific implementation, it can be shown in terminal screen described
The preview screen of environment to be captured.Specifically, terminal can carry out recognition of face processing to the preview screen, determine described
Human face region in preview screen.Further, terminal can be determined according to the color data of the pixel of the human face region
The face complexion data of the human face region.
Optionally, it (is in embodiments of the present invention people that terminal can also carry out object detection processing to the preview screen
Body detection process), determine the subject area (human region) in the preview screen.Further, terminal can also be by institute
Face complexion data are stated as object colour of skin data.
S12, according to the ambient light data and/or the object color data, determine present filming scene.
Specifically, when the object color data are object colour of skin data, terminal performs described according to the ambient light
Data and/or the object color data, determine that present filming scene can specifically include：According to the ambient light data, really
The environmental form of the fixed environment to be captured；According to the object colour of skin data, each object in the environment to be captured is determined
Colour of skin attribute；According to the environmental form and the colour of skin attribute, present filming scene is determined.
Wherein, the environment category can include but is not limited to outside room on daytime, in daytime room, half-light (night) etc..Institute
It states colour of skin attribute and includes colour of skin type and/or colour of skin rank.Wherein, the colour of skin type can include but is not limited to white, Huang
Color, black etc..Colour of skin rank can be used for characterizing the bright-dark degree of the colour of skin.It is understood that different colour of skin types has
Different colour of skin ranks.Since same colour of skin type is also divided into colour of skin light and shade, each colour of skin type has corresponding
Colour of skin rank.In a specific embodiment, the colour of skin rank can for example include 1 to 15 grades.Wherein, the 1st grade to the 5th
The corresponding colour of skin type of colour of skin rank of grade is white, and the 6th grade to the 10th grade of the corresponding colour of skin type of colour of skin rank is yellow,
11st grade to the 15th grade of the corresponding colour of skin type of colour of skin rank is black.It should be noted that colour of skin rank is higher, show skin
Color is brighter.
It should be noted that photographed scene can distinguish simple scenario and complex scene.Wherein, for simple scenario, field
There is no the king-sized place of light and shade difference in scape, when terminal is shot by automatic exposure be not in local overexposure or owe exposure
Situation.For complex scene, existing very bright place in scene, and have very dark place, terminal is carried out by automatic exposure
It is easy to appear local overexposure or the deficient situations exposed during shooting.
In a specific embodiment, when there is the object with different colour of skin ranks in the environment to be captured,
Terminal may determine that present filming scene is complex scene.If for example, in the environment to be captured existing white man have again it is black
People, then terminal may determine that present filming scene is complex scene.In another example if there are two in the environment to be captured
When colour of skin rank is respectively the 6th grade and the 10th grade of yellow, then terminal may determine that present filming scene is complicated field
Scape.
In a specific embodiment, when environmental form and colour of skin type meet the first preset relation, terminal can be with
It is complex scene to judge present filming scene.Wherein, when the brightness value of the environment to be captured and the skin of one of object
When colour brightness light and shade is widely different, terminal can determine that environmental form meets the first preset relation with colour of skin type.For example, work as ring
Border type is daytime, there are the object that colour of skin type is black in the environment to be captured, alternatively, when environmental form is half-light,
There are during the object that colour of skin type is white in the environment to be captured, terminal can determine that environmental form and colour of skin type meet
First preset relation.
If S13, the present filming scene are preset photographed scene, according to the ambient light data and described right
As color data sets at least two groups of exposure parameters, and the environment to be captured is shot according to the exposure parameter of setting.
Wherein, the preset photographed scene is above-mentioned complex scene.It is understood that only in present filming scene
During for complex scene, terminal just needs to set multigroup (at least two groups) exposure parameter.
Specifically, terminal can be that the object with different colour of skin ranks sets different exposure parameters.For example, when described
When in environment to be captured there are two colour of skin types being respectively the object of yellow and black, terminal can be that described two objects be set
Put two groups of different exposure parameters.Wherein, the exposure parameter can include but is not limited to time for exposure, f-number, shutter speed
Degree etc..
Further, terminal can also be that the environment to be captured sets exposure parameter.Specifically, when environmental form and skin
When color type meets the second preset relation, terminal can be that one group of exposure parameter is separately provided in the environment to be captured, which exposes
Optical parameter is different from any group of exposure parameter for object setting.Wherein, when the brightness of the environment to be captured with it is all right
When the skin brightness light and shade difference of elephant is very big, terminal can determine that environmental form and colour of skin type meet the second preset relation.
For example, working as environmental form for daytime, the colour of skin type of all objects is black in the environment to be captured, alternatively, working as environment
Type is half-light, and when the colour of skin type of all objects is white in the environment to be captured, terminal can determine environmental form
Meet the second preset relation with colour of skin type.Specifically, when environmental form and colour of skin type are unsatisfactory for the second preset relation, eventually
End can be that current environment sets one group of exposure parameter, this group of exposure parameter is joined with one of which exposure of the terminal for object setting
Number is identical.For example, when environmental form is daytime, had altogether in the environment to be captured there are two the object that colour of skin type is yellow,
And during the colour of skin rank difference of described two objects, terminal can be colour of skin rank higher in current environment and described two objects
Object identical exposure parameter is set.
Further, under every group of exposure parameter of setting, terminal can quickly be shot respectively, obtain multiple shootings
Image.Optionally, terminal can also store multiple shooting images that shooting obtains.
S14, the image obtained to shooting carry out synthesis processing, obtain target image.
Specifically, terminal performs the image that described pair of shooting obtains and carries out synthesis processing, and obtaining target image can be specific
Including：Object detection is carried out to the shooting image that shooting obtains to handle to obtain background area and at least one subject area；It determines
Shoot the background area in obtained each shooting image and the interpolation weights of each subject area；According to the interpolation weight determined
Weight is overlapped processing to the obtained each shooting image that shoots, obtains target image.Further, terminal can be with
It is exported in screen and stores the target image.
Wherein, the object detection processing for example can be human testing processing.
It is understood that each shooting image has corresponded to unique one group of exposure parameter.It should be noted that Mr. Yu
A shooting image, exposure parameter can be that the exposure parameter of only targeted object region setting (is an object or more
A colour of skin rank it is identical object setting exposure parameter) or only background area setting exposure parameter (be
The exposure parameter of the environment setting to be captured), it can also be the exposure ginseng for targeted object region and background area setting
Number.So as to which for each shooting image, exposure parameter has all corresponded to subject area and/or background area.
Specifically, for some shooting image, terminal can be by the corresponding region of its exposure parameter (including subject area
And/or background area) interpolation weights be set as the first weighted value, the interpolation weight in other regions in the shooting image is reseted
It is set to the second weighted value.For example, when the environment to be captured includes the first object and second two objects of object, wherein,
The colour of skin rank of first object and the second object is identical, and the light and shade of the environment to be captured and two objects is widely different.
So as to which, terminal can be that first object and the second object set the first exposure parameter, for the environment setting to be captured the
Two exposure parameters, and according to the first exposure parameter and the second exposure parameter the environment to be captured is shot respectively to obtain
One shooting image and the second shooting image.So, terminal carries out pair to the described first shooting image and/or the second shooting image
As background area, the first subject area and the second subject area can be obtained after detection process.Image is shot for described first,
Its first acquisition parameters has corresponded to first subject area and the second subject area, so as to which terminal can be by described first pair
As the interpolation weights in region and the second subject area are set as first weighted value, the interpolation weight of the background area is reseted
It is set to second weighted value.For the described second shooting image, the second acquisition parameters have corresponded to the background area, from
And the interpolation weights of the background area can be set as first weighted value by terminal, by first subject area and
The interpolation weights of second subject area are set as second weighted value.
In a specific embodiment, first weighted value is 1, and second weighted value is 0.
In embodiments of the present invention, terminal is detecting that present filming scene is light and shade difference of the different objects in the colour of skin
The very big or light and shade of environment and the object colour of skin is widely different when complex scenes, according to specific ambient light data and the object colour of skin
Data set multigroup exposure parameter, and are shot according to the exposure parameter of setting to obtain multiple shooting images, then to shooting
Obtained multiple shooting images carry out synthesis processing, so as to obtain the target area that exposure takes into account varying environment, the different colours of skin
The more suitable target image of the brightness of domain and background area.
Fig. 2 is referred to, is the schematic flow diagram of another image pickup method provided in an embodiment of the present invention.In the specific implementation,
Each step that this method includes can be performed by terminal.Image pickup method as shown in Figure 2 can include：
S21, the ambient light data and object color data for obtaining environment to be captured.
Wherein, the ambient light data for example can be ambient brightness value, and the object color data can be specially pair
As colour of skin data.
It should be noted that the particular technique details of step S21 can refer to the phase of the application step S11 shown in FIG. 1
It closes part to describe, details are not described herein.
S22, according to the ambient light data and/or the object color data, determine present filming scene.
Wherein, photographed scene can distinguish simple scenario and complex scene.For simple scenario, there is no the light and shade poor in scene
Different king-sized place is not in local overexposure or owes the situation exposed when terminal is shot by automatic exposure.For multiple
Miscellaneous scene, existing very bright place in scene, and have very dark place, terminal is easy to out when being shot by automatic exposure
Current situation portion overexposure owes the situation exposed.
It should be noted that the particular technique details of step S22 can refer to the phase of the application step S12 shown in FIG. 1
It closes part to describe, details are not described herein.
If S23, the present filming scene are preset photographed scene, set for the object in the environment to be captured
Put the first exposure parameter set.
Wherein, the preset photographed scene is above-mentioned complex scene.
Wherein, the number of exposure parameter is determined according to the colour of skin rank in the first exposure parameter set.Specifically,
Terminal can be that the object with different colour of skin ranks sets different exposure parameters.For example, it is deposited when in the environment to be captured
When two colour of skin types are respectively the object of yellow and black, terminal can be that described two objects set two groups of different exposures
Optical parameter.Wherein, the exposure parameter can include but is not limited to time for exposure, f-number, shutter speed etc..
S24, judge whether the environmental form meets the second preset relation with the colour of skin type.
Wherein, when the skin brightness light and shade difference of the brightness of the environment to be captured and all objects is very big, terminal
It can determine that environmental form and colour of skin type meet the second preset relation, otherwise can determine that environmental form and colour of skin type are discontented with
The second preset relation of foot.For example, working as environmental form for daytime, the colour of skin type of all objects is black in the environment to be captured
Color, alternatively, working as environmental form for half-light, when the colour of skin type of all objects is white in the environment to be captured, terminal can
To determine that environmental form and colour of skin type meet the second preset relation.
When environmental form and colour of skin type meet the second preset relation, terminal can perform step S25；Work as environmental form
