During the preview image of photographed scene, Moving Objects detection is carried out to photographed scene, testing result is obtained.
In actual applications, because every two field picture can characterize the state of object at a time in photographed scene respectively,
Therefore, if object is moved in photographed scene, two adjacent frame preview images will have differences, adjacent by comparing
Two frame preview images, just can realize the detection to Moving Objects in photographed scene, and then obtain testing result.
If specifically, the motion amplitude of object is larger in photographed scene, the difference of adjacent two frame preview images will be compared with
Greatly, when carrying out dynamic range adjustment, if such two frames preview image is directly synthesized, ghost image will easily occur, influence is clapped
According to effect.It therefore, it can the difference degree according to adjacent two frames preview image, determine in photographed scene with the presence or absence of motion pair
As.If the difference of adjacent two frames preview image is more than predetermined threshold value, it is determined that there are Moving Objects in the photographed scene, if adjacent
The difference of two frame preview images is less than predetermined threshold value, it is determined that Moving Objects are not present in photographed scene.
Step 102, if receiving photographing instruction, according to testing result, dynamic range adjustment mode is determined.
In actual applications, the preview graph that photographed scene is gathered in camera can be transferred after photographing instruction is received
The testing result obtained as during, and according to the testing result, it is determined that being adapted to the dynamic range adjustment side of present filming scene

In summary, in the embodiment of the present invention, by during the preview image that camera gathers photographed scene, to clapping
Take the photograph scene and carry out Moving Objects detection, obtain testing result.If receiving photographing instruction, according to the testing result, it is determined that dynamic
State scope adjustment mode, and according to the dynamic range adjustment mode, dynamic range parameters are adjusted, export photo.So that
Can be using suitable dynamic range adjustment mode under all kinds of photographed scenes, and then be prevented effectively from during dynamic range enhancing
The negative effect of initiation, lifts picture quality.
Reference picture 2, shows the flow chart of another photographic method of the embodiment of the present invention.The side that the present embodiment is provided
Method can be performed by mobile terminal, and photographic method includes：
Step 201, during the preview image that camera gathers photographed scene, Moving Objects inspection is carried out to photographed scene
Survey, judge to whether there is Moving Objects in photographed scene.
When user prepares to take pictures to a certain photographed scene, shooting can be passed through before photographing instruction is received
First-class image capture device is found a view photographed scene in advance, to obtain at least two frame preview images of the photographed scene.And
The preview image obtained when finding a view is prestored into memory, device for processing carries out preview image processing.
Because when there are Moving Objects in photographed scene, generally two adjacent frame preview images can have notable difference.
It therefore, it can, by analyzing the difference between two frame preview images, determine to whether there is Moving Objects in photographed scene.
Specifically, can contrast find a view during difference between two frame preview images adjacent in the preview image that obtains
It is different.If difference is more than predetermined threshold value, it is determined that there are Moving Objects in photographed scene, can perform step 202 and determine dynamic model
Enclose the mode of adjustment；If difference is less than predetermined threshold value, it is determined that Moving Objects are not present in photographed scene, step can be performed
203 determine the mode of dynamic range adjustment.
Step 202, if there are Moving Objects in photographed scene, it is determined that carried out by the way of being exposed single frames spatial domain more
Dynamic range is adjusted.
In order to shoot the reference object that dynamic range is larger, the HDR technologies generally used in the prior art are that enclosed is more
Expose photosynthetic mode., it is necessary to which shooting at least three frame preview images carries out image when carrying out dynamic range enhancing using which
Synthesis.At least three frame preview images are generally made up of the preview image of three kinds of different depth of exposures, wherein, a kind of preview image
For under exposed preview image, another preview image is the preview image of normal exposure, and another preview image is overexposure
Preview image.Highlighted details is retained by under exposed preview image, dark place details is lifted using the preview image of overexposure,
The details of intermediate luminance is ensured by the preview image of normal exposure again, so as to retain the details of the brightness of each in photographed scene.
However, because this mode needs the synthesis of multiframe preview image to realize, when there are Moving Objects in photographed scene, shooting
The multiframe preview image got off occurs in different preview images between the inconsistent phenomenon of Moving Objects form, i.e. preview image
Differ greatly.In this case, when the preview image that multiframe difference is more than predetermined threshold value is synthesized, easily there is ghost image,
Cause image degradation.
In order to avoid difference exceed threshold value multiframe preview image synthesis cause ghost image, when in photographed scene exist motion pair
As when, the embodiment of the present application carries out dynamic range adjustment more by the way of being exposed single frames spatial domain.Being exposed the single frames spatial domain more
The mode of light refers to, by being exposed at least twice in single frames spatial domain to realize the enhanced mode of dynamic range, specifically
Including the mode such as zigzag HDR and adaptive dynamic range correction.Because the mode exposed single frames spatial domain need not more
Image synthesis processing is carried out to multiframe preview image, so that when effectively prevent shooting Moving Objects, between multiframe preview image
Difference cause synthesis when there is ghost image.
Wherein, zigzag HDR refers to by controlling the pixel in COMS sensor, first to single frames preview image
Interior different zones are exposed according to different exposure time, then by the image co-registration of different zones, to reach enhancing dynamic range
Purpose.
Wherein, adaptive dynamic range correction refers to, according to single-frame images data, be made whether as group each pixel
The judgement of information point is knitted, the value that will represent the point of organizational information is averaged and obtains organizational information average.It is equal further according to organizational information
Value adjusts the position of the point of rotation, it is ensured that the organizational information brightness of image is held essentially constant before and after dynamic range is adjusted, and
Weak signal and strong signal are compressed or stretched as required, so as to realize the enhanced purpose of dynamic range.
Step 203, if Moving Objects are not present in photographed scene, according to the first exposure area and second in preview image
Corresponding exposure value is distinguished in exposure area, determines dynamic range adjustment mode.
Specifically, a frame preview image of camera collection can be obtained, and determine the first exposure in the preview image
Behind region and the second exposure area, the first exposure value of the first exposure area and the second exposure value of the second exposure area are obtained.
If testing result indicates that Moving Objects are not present in photographed scene, exposed according to first of the first exposure area in the preview image
Light value and the second exposure value of the second exposure area, it may be determined that the exposure ratio of the first exposure area and the second exposure area,
According to the exposure ratio, it may be determined that be adapted to the dynamic range adjustment mode of the photographed scene.In actual applications, photographed scene
It is interior generally to there is the higher region of brightness and the relatively low region of brightness, the corresponding different exposure value in region of different brightness, brightness
Higher region needs relatively low exposure value, i.e. the time for exposure is shorter；The relatively low region of brightness needs higher exposure value, that is, exposes
It is longer between light time.Different zones luminance difference is bigger, then dynamic range is bigger., can in order to determine the dynamic range of photographed scene
To obtain during the corresponding preview image of photographed scene, every frame preview image is divided into brightness is relatively low to need the of time exposure
One exposure area, and higher the second exposure area for needing the short time to expose of brightness, and pass through first exposure area and second
The ratio of exposure area correspondence exposure value, determines the dynamic range of the photographed scene.
If specifically, the dynamic range that exposure ratio is less than the first proportion threshold value, i.e. photographed scene is relatively low, then can determine
Dynamic range adjustment mode is zigzag HDR adjustment mode.If for example, the first proportion threshold value is 2:1, when exposure ratio
Example is less than 2:When 1, the luminance difference in photographed scene between different zones is smaller, and Mobile state is entered using zigzag HDR
Scope adjustment just can effectively lift preview image quality.
If the ratio of exposure is more than or equal to the first proportion threshold value and less than or equal to the second proportion threshold value, i.e. photographed scene
Dynamic range is moderate, it may be determined that dynamic range adjustment mode be enclosed more expose photosynthetic mode.If for example, the first ratio
Threshold value is 2:1, the second proportion threshold value is 4:1, when exposure ratio is more than or equal to 2:1 and less than or equal to 4:When 1, it can use
Expose photosynthetic mode more enclosed, shoot at least three frame preview images and carry out image synthesis.At least three frame preview images lead to
The preview image of Chang Yousan kinds difference depth of exposure is constituted, wherein, a kind of preview image is under exposed preview image, another
Preview image is the preview image of normal exposure, and another preview image is the preview image of overexposure.By under exposed pre-
Image of looking at retains highlighted details, and dark place details, then the preview image for passing through normal exposure are lifted using the preview image of overexposure
Ensure the details of intermediate luminance, so as to retain the details of the brightness of each in photographed scene.
If the dynamic range that the ratio of exposure is more than the second proportion threshold value, i.e. photographed scene is higher, it may be determined that dynamic range
Adjustment mode be preview image and a frame after a frame is adjusted through zigzag HDR without dynamic range adjust it is pre-
Image of looking at carries out image synthesis.If for example, the second proportion threshold value is 4:1, when exposure ratio is more than 4:When 1, due to dynamic range
It is higher, after a frame preview image is adjusted through zigzag HDR, definition can be caused to reduce, and without dynamic range adjustment
Preview image definition it is higher.Therefore, in this case, the preview by the frame after the adjustment of zigzag HDR is passed through
Image is synthesized with a frame without the preview image that dynamic range is adjusted, and can effectively lift the definition of preview image, so as to keep away
Exempt from that individually a frame preview image is carried out to negatively affect caused by the adjustment of zigzag HDR is possible.
If the ratio of exposure is more than the second proportion threshold value, it is through zigzag by multiframe that can also determine dynamic range adjustment mode
Preview image after HDR adjustment carries out image synthesis, wherein, multiframe is pre- after the adjustment of zigzag HDR
Image of looking at has different exposure ratios respectively.
Specifically, in this case, dynamic range adjustment, overexposure are carried out according to photosynthetic mode is exposed enclosed more
Highlighted details is easily lost while dark place details is lifted, and under-exposure is easy to lose while highlighted details is lifted
Dark place details is lost, therefore characteristic point is difficult to find that in synthesis, so as to be difficult to effectively dynamic range adjustment.
By way of preview image synthesis in the embodiment of the present application after multiframe is adjusted through zigzag HDR
Dynamic range adjustment is carried out, the preview image after being adjusted due to each frame through zigzag HDR is by showing dark place details
The second exposure area synthesis of first exposure area and the highlighted details of performance, therefore, both will not be because of overexposure or under-exposure
Cause relevant details to be lost, can be strengthened dynamic range by the synthesis of multiframe preview image again, so as to effectively be lifted pre-
Look at picture quality.If for example, it is m that ratio is exposed under the photographed scene:1, then can be according to formula zzHDR (m:1)+zzHDR
((m-1):1)+zzHDR((m-2):1)+……+zzHDR(2:1) image synthesis, is carried out to preview image.I.e. by m:1、(m-
1):1、(m-2):1、2:The preview image after the adjustment of zigzag HDR of 1 grade exposure ratio carries out image synthesis, with
Realize that effectively dynamic range is adjusted.Wherein, zzHDR (m:1) it is m to refer to exposure ratio:1 through zigzag HDR adjust
Preview image after whole.
Step 204, according to the dynamic range adjustment mode, dynamic range parameters are adjusted, photo is exported.
According to testing result, the dynamic range of photographed scene, it is determined that being adapted to the dynamic range adjustment of present filming scene
After mode, just dynamic range parameters can be adjusted according to the dynamic range adjustment mode, photo be exported, so that more efficient keep away
Exempt from various HDR technologies issuable counter productive when carrying out dynamic range enhancing so that shooting all kinds of shootings
During scene, preferable dynamic range enhancing effect can be obtained, preferably reflects the visual effect in true environment.
In summary, in the embodiment of the present invention, by during the preview image that camera gathers photographed scene, to clapping
Take the photograph scene and carry out Moving Objects detection, judge to whether there is Moving Objects in photographed scene.If there is motion pair in photographed scene
As, it is determined that dynamic range adjustment is carried out by the way of being exposed single frames spatial domain more.If motion pair is not present in photographed scene
As then distinguishing corresponding exposure value according to the first exposure area in preview image and the second exposure area, determining that dynamic range is adjusted
Perfect square formula.According still further to the dynamic range adjustment mode, dynamic range parameters are adjusted, photo is exported.So that in all kinds of shootings
The dynamic range Adjustment effect obtained under scene, both can guarantee that the true reduction of dynamic range, the clear of preview image is can guarantee that again
Clear degree is not suffered a loss, and is prevented effectively from all kinds of negative effects that may trigger during dynamic range enhancing.
