- 4 are please referred to Fig.1, the sampling method of embodiment of the present invention can be applied to imaging device 200, and imaging device 200 is used
In shooting to obtain preview image 210.The sampling method of embodiment of the present invention may include following steps：
S1 extracts preview image 210 using as sample image 230 with sample interval；
S2, judges whether the diversity factor between front and back two frame sample images 230 is greater than or equal to predetermined difference degree；
S3 shortens sample interval when diversity factor is spent more than or equal to predetermined difference and return to step 1 and step 2 is straight
It is less than predetermined difference degree to diversity factor；And
S4 obtains current sample time interval and as reference time.
Referring to Fig. 2, the sampling method of embodiment of the present invention can be real by the sampler 110 of embodiment of the present invention
It is existing.Sampler 110 includes sampling module 111, judgment module 113, shortens module 115 and the first acquisition module 117.Sampling side
Method can be applied to the control method of embodiment of the present invention, and correspondingly, sampler 110 can be applied to embodiment of the present invention
Control device 100 and electronic device 1000.Control device 100 may include that control module 130, control module 130 can be according to references
Time obtains the time for exposure to control the exposure of imaging device 200.
The sampler 110 or control device 100 of embodiment of the present invention can be integrated in electronic device 1000, can also
It is to be external in 1000 main body of electronic device as independent equipment.It is integrated in electronic device 1000, makes 1000 structure of electronic device
Compact, function is more rich, and user uses more convenient.As external equipment, can flexibly be taken from different electronic devices 1000
Match, to promote the shooting performance of different electronic devices 1000.
Wherein, step S1 can be realized by sampling module 111, and step S2 can be realized that step S3 can be by contracting by judgment module 113
Short module 115 realizes that step S4 can be realized by the first acquisition module 117.
That is, sampling module 111 can be used for extracting preview image 210 using as sample image with sample interval
230；Judgment module 113 can be used for for judging it is pre- whether the diversity factor between front and back two frames sample image 230 is greater than or equal to
Determine diversity factor；Shorten module 115 and can be used for shortening when diversity factor is spent more than or equal to predetermined difference sample interval with weight
New sample drawn image 230 is until diversity factor is less than predetermined difference degree；First acquisition module 117 can be used for obtaining diversity factor and be less than
The sample interval of predetermined difference degree and as reference time.
Reference time can be used to reference to the suitable time for exposure is arranged.Reference time has certain positive with the time for exposure
Pass relationship, alternatively, reference time is the time for exposure in some embodiments.
Referring to Fig. 3, preview image 210 can be the preview that imaging device 200 is obtained by internal imaging sensor
Image 210, preview image 210 generally obtain at predetermined intervals.It in embodiments of the present invention, can be between this time
Every the sample interval of integral multiple extract preview image 210 and as sample image 230.Such as preview image 210
Time interval is 0.05 second, i.e., frame per second is 20Hz, if sample interval is 0.25 second, i.e. frame per second is 4Hz, that is, every 5
Preview image 210 extracts 1 preview image 210 and is used as sample image 230.
Then it can determine whether the diversity factor between front and back two frames sample image 230 is greater than or equal to predetermined difference degree, such as
Judge the diversity factor being separated by between 0.25 second adjacent two frames sample image 230.Sample drawn image 230 and when obtaining its sampling
Between the purpose that is spaced can be that the suitable time for exposure is obtained according to sample interval.If diversity factor is greater than or equal to predetermined
Diversity factor, if illustrating, the image taken using this sample interval as the time for exposure is had moving state tracks and seems fuzzy,
It is exactly that image meeting " flower " is fallen, therefore should shorten sample interval and be attempted again.
Referring to Fig. 4, diversity factor refers to the size of front and back two frames sample image, 230 difference, in general, if shot when shooting
Object 250 is moved with fast speed or imaging device 200 is shaken with faster speed, is easy to cause front and back two frames sample image 230
Diversity factor it is big, also just need to be imaged with shorter Time Exposure.The change in location size of identification object 250 can be passed through
To judge diversity factor, or the parameters such as brightness, colour temperature for comparing two frame sample images 230 change be turned to judge diversity factor according to
According to etc..Such as comparing the front and back two frames sample image 230 of Fig. 4, the displacement distance of 250 face of object therein is larger, if moving
Dynamic distance is more than certain threshold value, it is believed that diversity factor is more than predetermined difference degree.
It is sampled and judges by shortening sample interval repeatedly, finally obtaining makes front and back two frames sample image 230
Between diversity factor be just less than equal to predetermined difference degree sample interval, using this sample interval as when reference
Between.Subsequently can be set according to this reference time the time for exposure, to obtain more visible image.
In some embodiments, step S3 gradually shortens sample interval with predetermined ratio.That is, each
Predetermined ratio is multiplied by sample interval, exactly last sample interval.
So-called predetermined ratio can be the number more than 0 and less than 1 such as 1/2,1/5.The size of predetermined ratio, determines and takes
The convergent speed speed of sample time interval.If referring to Fig. 5, for example, initial sample interval be 1 second, preview image 210
Time interval be 0.05 second, i.e., every 20 preview images 210 extract 1 and are used as sampled images, if predetermined ratio is 1/2,
Sample interval next time is 1*1/2=0.5 seconds, i.e., every 10 preview images 210 extract one and are used as sampled picture, under
Next then be 0.5*1/2=0.25 second, i.e., every 5 preview images 210 extract one and are used as sampled picture ....
The diversity factor for judging front and back two frame sample images 230 behind shortening sample interval every time, until diversity factor is less than
No longer shorten sample interval when predetermined difference is spent.Such as when sample interval is 0.25 second, diversity factor satisfaction is less than
The condition of predetermined difference degree then stops shortening, and with 0.25 second for reference time.It it is sample time using the benefit for the mode of multiplying is passed
Interval convergence is very fast, therefore can relatively quickly find suitable reference time.
Certainly, not unlimitedly sample interval can be shortened.In some embodiments, step S3 is first
Shorten sample interval within the scope of time interval, the lower limit of wherein first time interval range includes adjacent two frames preview image
210 time interval.
For example, in the example of the above embodiment, the time interval of preview image 210 is 0.05 second, and between sample time
Every the time interval for being unable to preview image 210 certainly.Therefore when sample interval shortening 4 times, reach 1* (1/2)4=
At 0.0625 second, if diversity factor is still unsatisfactory for the condition less than or equal to predetermined difference degree, also no longer shorten.It is not due to 0.0625
0.05 multiple, can use 0.05 second is sample interval, i.e., each 210 extraction of preview image is used as sample image 230.
By the way that lower limit is arranged, can avoid ceaselessly carrying out operation and sampling.
In addition to sample interval to be gradually multiplied by a ratio value to shorten, in other certain embodiments, also may be used
By using in a manner of successively decreasing or the algorithm of other reductions.
What is inquired into embodiment of above is that gradually sample interval is contracted when initial sample interval is long
It is short also to obtain suitable reference time.Then, sometimes initial sample interval is too short, can also gradually prolong sample time
Length is to obtain suitable reference time.
Fig. 6-7 is please referred to, in some embodiments, sampling method includes the following steps upon step s 2：
S3a, when diversity factor is spent less than predetermined difference extend sample interval and return to step S1 and step S2 until
Diversity factor is greater than or equal to predetermined difference degree.
Step S3a can be realized by the extension module 116 of the sampler 110 of certain embodiments, that is to say, that extend mould
Block 116 be used to extend when diversity factor is spent less than predetermined difference sample interval and again sample drawn image 230 up to poor
Different degree is greater than or equal to predetermined difference degree.
If diversity factor is less than predetermined difference degree, illustrate that exposure is can to obtain clearly using this diversity factor as the time for exposure
Image, but the time for exposure is too short, it is possible to cause the light-inletting quantity of imaging sensor insufficient and makes the brightness of image not enough or make an uproar
Point is more.Therefore sample interval can be appropriately extended to obtain meeting diversity factor less than predetermined difference degree condition while light-inletting quantity
The sufficient time for exposure.
Fig. 8-9 is please referred to, in some embodiments, sampling method includes after step S3a：
S4a obtains the sample interval before this step S3a as reference time.
Wherein step S4a can realize by the second acquisition module 118 of the sampler 110 of certain embodiments, i.e., second
Acquisition module 118 for obtain diversity factor be less than and closest to the corresponding sample interval of predetermined difference degree as reference when
Between.
That is, finally obtaining corresponding sample interval of the diversity factor more than or equal to predetermined difference degree as ginseng
It is inappropriate according to the time, if because diversity factor is greater than or equal to predetermined difference degree and means to expose meeting with this sample interval
Obtain fuzzy image.Therefore the corresponding diversity factor before selecting this sample interval to be extended is less than taking for predetermined difference degree
Sample time interval.
For example, the time interval of preview image 210 is 0.05 second, i.e., frame number is 20Hz, and initial sample time interval is
0.05 second, with 2 times of prearranged multiple extension sample intervals, i.e., obtain successively 0.1 second, 0.2 second, sampling in 0.4 second ... ... when
Between be spaced.If when sample interval is 0.4 second, the diversity factor of just front and back two frame sample images 230 is greater than or equal to
Predetermined difference degree should then take 0.2 second, that is, meet corresponding diversity factor less than between the longest sample time of predetermined difference degree
Every for reference time.
In the sampling method of certain embodiments, step S3a extends sample interval with prearranged multiple.
Sample interval is passed using predetermined total number as multiplier and is multiplied.Example as described above in embodiment in example 2
Extend sample interval as prearranged multiple again.By the way of passing and multiplying, sample interval amplification is very fast, therefore can be very fast
Suitable sample interval is found fastly as reference time.
If however, corresponding difference value always be less than predetermined difference value, also can not indefinite extension sample interval.
In certain embodiments, step S3a extends sample interval within the scope of the second time interval.Second time interval range
The upper limit includes system default time interval.
System default time interval can be sampler 110 or the preset time interval of 200 internal system of imaging device.
If such as sample interval reaches corresponding diversity factor when system default time interval and no longer prolongs still less than predetermined difference degree
Long sample interval, but directly using system default time interval as reference time to obtain the time for exposure.
Or the upper limit of the second time interval range of setting, that is, maximum sample time can also be inputted according to user
Interval.I.e. in some embodiments, sampling method may include：
S5 inputs the upper limit of the second time interval range of setting according to user.
Step S5 can be realized that is, (figure is not for setup module by the setup module of the sampler 110 in certain embodiments
Show) for inputting the upper limit that the second time interval range is arranged according to user.
In this way, the upper limit of the second time interval range can be independently arranged in user, it can thus adjust sampler 110 and obtain ginseng
According to the time length of time, user experience can be promoted.
To sum up, by the way that the upper limit of the second time interval range is arranged, make sampling method and sampler 110 will not be without limitation
Ground extends sample interval.
Also referring to Figure 10 and Fig. 2, the control method of embodiment of the present invention can be wrapped for controlling imaging device 200
Include the sampling method in the above embodiment；And
The time for exposure is arranged according to reference time to control the exposure of imaging device 200 in S6.
The control method of embodiment of the present invention is realized, control device by the control device 100 of embodiment of the present invention
100 include the sampler 110 of control module 130 and embodiment of the present invention.
Wherein, control module 130 is used to that the time for exposure to be arranged according to reference time to control the exposure of imaging device 200.
In this way, the suitable time for exposure can be obtained according to reference time, so that in exposure process, the dynamic that scene occurs becomes
Change negligible, the moving state tracks that can be obviously identified to make the image shot not have, and clarity is higher.
