Fig. 2 is a kind of flow chart of image capturing method according to another exemplary embodiment, as shown in Fig. 2 should
Image capturing method is used in above-mentioned terminal, i.e., the terminal is configured with the first camera assembly and the second camera assembly, and this first is taken the photograph
As the high resolution of component is in the resolution ratio of second camera assembly, and the pixel size of first camera assembly be less than this
The pixel size of two camera assemblies.The image capturing method can realize step including following：
In step 201, under background blurring pattern, determine that the terminal is currently located the light intensity value of environment.
In practical application scene, the terminal can be provided with background blurring option, and the background blurring option can be thing
Manage button, or virtual key.When user needs to be shot using background blurring pattern, background void can be clicked on
Change option, to trigger background blurring instruction.Correspondingly, after terminal receives the background blurring instruction, the background blurring mould is started
Formula, in this way, user can be shot under the background blurring pattern.
Certainly, only it is to be carried out by the terminal exemplified by the background blurring pattern is started after receiving background blurring instruction here
Illustrate, in practical application scene, the terminal, which can also be given tacit consent to, starts the background blurring pattern, that is to say, the terminal is being opened
After screening-mode, the automatic start background blurring pattern, the embodiment of the present disclosure is not limited this.
As it was noted above, during due to being shot under background blurring pattern, may if the light of external environment is stronger
Due to not high etc. enough reason of camera assembly resolution ratio, easily cause the image sharpness of shooting inadequate, if conversely, external environment
Light is weaker, then may easily cause the picture brightness shot inadequate, noise is more due to light intensity is inadequate.
In order to be adapted to the light intensity of external environment, the embodiment of the present disclosure determines that the terminal is currently located the luminous intensity of environment
Value.
In the specific implementation, determining that the terminal is currently located the specific implementation of the light intensity value of environment and can included：Pass through
The CMOS detection luminous intensity of terminal configuration, and determined by the sensor devices corresponding to detected luminous intensity
Light intensity value.
In step 202, when receiving shooting instruction, object to be shot is clapped by first camera assembly
Take the photograph, obtain the first shooting image, and the object to be shot is shot by second camera assembly, obtain the second shooting
Image.
Wherein, shooting instruction can be triggered by user, and the user can be triggered by assigned operation, and the assigned operation can
So that including clicking operation, slide etc., the embodiment of the present disclosure is not construed as limiting to this.
For example, being provided with shooting option in the terminal, the shooting option can be physical button, or virtually press
Key.When user wants to shoot object to be shot, the shooting option can be clicked on, is instructed with triggering above-mentioned shooting.
When terminal receives shooting instruction, it may be determined that user will shoot to object to be shot.Herein, it is
Lifting shooting effect, the terminal is shot by two camera assemblies configured to the object to be shot respectively, to deserved
To first shooting image and second shooting image.For example, obtained first shooting image and second shooting image point
Other A and B.
In step 203, based on the light intensity value, the selection target from first shooting image and second shooting image
Shooting image, the target shooting image refer to the image for treating virtualization processing.
In practical implementations, due to finally to export a shooting image, therefore, terminal passes through above-mentioned two camera assembly
Shot to obtain after the first shooting image and the second shooting image, it is necessary to from first shooting image and second shooting image
In select as the main shooting image of main output, obtained most in order to subsequently carry out virtualization process to the main shooting image
Whole output image, i.e. terminal select to treat the target shooting figure of virtualization processing from first shooting image and second shooting image
Picture.
In the specific implementation, above-mentioned be based on the light intensity value, selected from first shooting image and second shooting image
The following two kinds situation can be included by selecting the specific implementation of target shooting image：
The first situation：When the light intensity value is more than preset strength, first shooting image is defined as the target and clapped
Take the photograph image.
Wherein, the preset strength can also be given tacit consent to and be set by user's self-defined setting according to the actual requirements by the terminal
Put, the embodiment of the present disclosure is not limited this.
When the light intensity value is more than the preset strength, illustrate the terminal be presently in environment light it is stronger, such as above
It is described, because the size of the pixel of camera assembly may decide that the brightness of shooting image, therefore, if now that resolution ratio is relative
, may when the second shooting image determination that the second camera assembly relatively low, that pixel is of a relatively high shoots to obtain is main shooting image
Due to not high etc. enough reason of camera assembly resolution ratio, cause the definition of second shooting image relatively low, it is final defeated so as to cause
The definition for going out image is relatively low.
Therefore, when the light intensity value is more than the preset strength, i.e., terminal be presently in environment light it is stronger when, can will
The the first shooting image selection for shooting to obtain by first camera assembly is main shooting image, will pass through the first shooting group
The first shooting image that part shoots to obtain is defined as target shooting image, for example, now determining that target shooting image is A.Also
It is to say, now, using first camera assembly as main camera assembly, the second camera assembly is as second camera component.
Second of situation：When the light intensity value is less than or equal to the preset strength, second shooting image is defined as
The target shooting image.
When the light intensity value is less than or equal to the preset strength, illustrate the terminal be presently in environment illumination it is weaker,
As it was noted above, because the size of the pixel of camera assembly determines the brightness of shooting image, therefore, if now by resolution ratio phase
, can when the first shooting image determination that first camera assembly relatively low to higher, pixel shoots to obtain is main shooting image
It due to luminance shortage, can cause that the noise of first shooting image is more, brightness is low, so as to cause final output image
Brightness it is relatively low.
Therefore, when the light intensity value is less than or equal to the preset strength, i.e., terminal be presently in environment light it is weaker when,
Can be main shooting image by the second shooting image selection for shooting to obtain by second camera assembly, will by this second
The second shooting image that camera assembly shoots to obtain is defined as target shooting image, for example, now determining that target shooting image is
B.That is, now, using second camera assembly as main camera assembly, the first camera assembly is as second camera component.
It should be noted that it is above-mentioned be only by by the light intensity value compared between preset strength exemplified by, in reality
, can also be by judging the scope residing for the light intensity value come from first shooting image and second shooting image in realization
Selection target shooting image.
For example, when the light intensity value is in the first preset range, first shooting image is defined as target shooting
Image, when the light intensity value is in the second preset range, second shooting image is defined as the target shooting image.Its
In, the lower limit of first preset range can be more than the upper limit of second preset range, also, first preset range and this
Two preset ranges can be by user's self-defined setting according to the actual requirements, can also be real by the terminal default setting, the disclosure
Example is applied not limit this.
In step 204, based on first shooting image and second shooting image, the depth of field is determined.
For the ease of subsequently carrying out background blurring processing to the above-mentioned target shooting image selected, need exist for being based on being somebody's turn to do
First shooting image and second shooting image determine the depth of field, will first shooting image and second shooting image compared
Compared with to determine the depth of field.It that is to say, it is another after first shooting image and second shooting image determine target shooting image
Open shooting image and actually here function as auxiliary calculating effect.Such as, however, it is determined that first shooting image is target shooting figure
Picture, then second shooting image is actually to be used to aid in calculating the depth of field, or, however, it is determined that second shooting image is that target is clapped
Image is taken the photograph, then first shooting image is actually used to aid in calculating the depth of field.
Further, in practical implementations, it is above-mentioned that the depth of field is determined based on first shooting image and second shooting image
Specific implementation can include：Based on first shooting image and second shooting image, by binocular stereo vision algorithm, really
The fixed depth of field.
It should be noted that based on first shooting image and second shooting image, pass through binocular stereo vision algorithm
Determine that the specific implementation of the depth of field may refer to correlation technique, the embodiment of the present disclosure is not described in detail herein.
In step 205, based on the depth of field, virtualization processing is carried out to the target shooting image, obtains the final output figure
Picture, to realize image taking.
When it is determined that after the depth of field, carrying out Fuzzy Processing to the background of determined main shooting image based on the depth of field, that is, be based on
The depth of field carries out virtualization processing to the target shooting image, so as to obtain final output image.
If for example, the light intensity value that the terminal is currently located environment is more than above-mentioned preset strength, i.e. the terminal is presently in
The light of environment is stronger, then the target shooting image that can determine to select by above-mentioned implementation procedure is A, here, the terminal
Based on the depth of field, virtualization processing is carried out to the target shooting image, obtains final output image.
In this way, light intensity of the terminal according to external environment, based on first camera assembly and the second camera assembly, automatically
Switch main camera assembly, solve under background blurring pattern, due to camera assembly resolution ratio when the light of external environment is stronger
It is not high enough, cause the image sharpness of shooting poor, or, the picture brightness shot is caused because the light of external environment is weaker
Not enough, the problem of noise is more, background blurring effect is improved.
It should be noted that the embodiment of the present disclosure is realized based on the luminous intensity by above-mentioned steps 203 to step 205
Value, first shooting image and second shooting image, the step of determining final output image.
Further, after obtaining the final output image, the final output image can be locally stored in the terminal, namely
It is, for a user, after it is determined that terminal-pair object to be shot has performed shooting operation, in the shooting that can locally inquire
Image is the final output image, that is to say, that above-mentioned first shooting image and above-mentioned second shooting image are for user
It is non.
