Embodiment
Exemplary embodiment of the present is described in detail now, its example is illustrated in the accompanying drawings, wherein, identical
Label represents same parts all the time.Below with reference to the accompanying drawings embodiment is described to explain the present invention.
Fig. 1 is the flow chart for the method for showing control image working sensor according to an exemplary embodiment of the present invention.
As shown in figure 1, in step S101, controlling the first imaging sensor shooting image.
In step s 102, the image that the first imaging sensor of detection is shot whether there is light and dark band.

Band the step of can be：The image that described first image sensor is shot is divided into multiple regions；Detecting each region is
It is no to there is light and dark band；When the ratio that the region that there is light and dark band accounts for Zone Full reaches predetermined threshold
When, it is determined that there is light and dark band in the image that described first image sensor is shot.
For example, the size for the image that can be shot according to the first imaging sensor, the image that the first imaging sensor is shot
Multiple regions (for example, described image can be divided into 7 × 6 42 regions) are divided into, then detect whether each region deposits
In light and dark band, when the ratio that the region that there is light and dark band accounts for Zone Full reaches predetermined threshold, then

The multi-frequency of correspondence alternating current has a variety of set of frequency for being used to eliminate Hz noise (for example, for eliminating 50 hertz of works
The set of frequency of frequency interference and the set of frequency for eliminating 60 hertz of Hz noises).When being shot under illumination light indoors
When, the frequency for being used to eliminate the power supply of the set of frequency and interior lighting system of Hz noise of only imaging sensor keeps one
Cause, then the image exported does not just have light and dark band (Flicker phenomenons).Therefore, exemplary embodiment of the present
Control image working sensor method be exactly to imaging sensor be used for eliminate 50 hertz of Hz noises set of frequency and
Set of frequency for eliminating 60 hertz of Hz noises is switched over, so that light and dark band is not present in the image of output.
In one example, the set of frequency for being used to eliminate Hz noise of described first image sensor can exist to be advance
The set of frequency for being used to eliminate Hz noise set in first imaging sensor.For example, user will can be used to eliminate 50 hertz
The set of frequency of Hz noise eliminates the set of frequency of Hz noise as being used for of being set in advance in the first imaging sensor,
When controlling the first imaging sensor shooting image under the set of frequency for eliminating 50 hertz of Hz noises, first is detected
When the image that the image and the second imaging sensor that imaging sensor is shot are shot all has light and dark band, then by first
The set of frequency for being used to eliminate Hz noise of imaging sensor is switched to another set of frequency (example for being used to eliminate Hz noise
Such as, the setting of 60 hertz of Hz noise frequencies is eliminated), and control the first imaging sensor to be used to eliminate Hz noise another
Shooting image under set of frequency, then export is used to eliminate the first imaging sensor under the set of frequency of Hz noise another
The image of shooting.But the invention is not restricted to this, set in advance in the first imaging sensor be used for eliminate Hz noise
Set of frequency can also be the set of frequency for eliminating 60 hertz of Hz noises.
In another example, the set of frequency for being used to eliminate Hz noise of described first image sensor can be second
The currently stored set of frequency for being used to eliminate Hz noise of imaging sensor.Now, the first imaging sensor and the second image
Sensor may be arranged in same electronic equipment, and the first imaging sensor is master image sensor (for example, rearmounted image sensing
Device), the second imaging sensor is sub-picture sensor (for example, preposition imaging sensor).For example, the second figure can used every time
When being shot as sensor, what the second imaging sensor of storage was used is applied to eliminate the set of frequency of current Hz noise.
In every the first imaging sensor of secondary control shooting image, call the second imaging sensor is currently stored to be done for eliminating power frequency
The set of frequency disturbed, allows users to enter optimal shooting state faster.For example, entering pedestrian using the second imaging sensor
When outlook is other or recognizes the operations such as eyeball rolling, the second imaging sensor can photograph the environmental information of surrounding simultaneously, at this moment,
Second imaging sensor can be stored in the set of frequency for being applied to eliminate the Hz noise of current environment used during current shooting,
So, when needing the first imaging sensor shooting image of control, the first imaging sensor can directly invoke the second image sensing
The set of frequency for being used to eliminate Hz noise of device last time storage.Because the region at user is generally in a period of time
Do not have larger variation inside, therefore the frequency of the power supply of the interior lighting system used in the region will not also change,
Therefore it can be used family in the initial image with regard to that can obtain in the absence of light and dark band of shooting using the method for this example, make
User obtains optimal usage experience in the very first time.
The method of control image working sensor according to an exemplary embodiment of the present invention, according to the second imaging sensor
The testing result of the image of shooting switches the set of frequency for being used to eliminate Hz noise of the first imaging sensor.
Alternatively, when the image that the second imaging sensor is shot has light and dark band, step S105 is performed：Will
The set of frequency for eliminating Hz noise of first imaging sensor is switched to another frequency for being used to eliminate Hz noise and set
Put, and control the first imaging sensor it is another for eliminate Hz noise set of frequency under shooting image.When the second image
When light and dark band is not present in the image that sensor is shot, step S104 is performed：The use of the first imaging sensor is not switched
In the set of frequency for eliminating Hz noise.
Specifically, it is in the first imaging sensor and the second imaging sensor under identical lighting environment, when first
When the image that the image and the second imaging sensor that imaging sensor is shot are shot all has light and dark band, illustrate first
The frequency of the power supply for being currently used in the set of frequency and interior lighting system that eliminate Hz noise of imaging sensor is inconsistent, needs
The set of frequency for being used to eliminate Hz noise of first imaging sensor is switched to another frequency for being used to eliminate Hz noise
Set to eliminate band light and dark present in image.
In one example, when the image that the second imaging sensor is shot has light and dark band, by the first figure
As sensor be used for eliminate Hz noise set of frequency automatically switch to it is another be used to eliminate the set of frequency of Hz noise,
And control the first imaging sensor it is another for eliminate Hz noise set of frequency under shooting image.In this example, when
When all there is light and dark band in the image that the image and the second imaging sensor that the first imaging sensor is shot are shot, without
It is artificial to participate in, the set of frequency for eliminating Hz noise of the first imaging sensor can be switched to automatically another for eliminating
The set of frequency of Hz noise carrys out shooting image.For example, under the set of frequency for eliminating 50 hertz of Hz noises, when first
When all there is light and dark band in the image that the image and the second imaging sensor that imaging sensor is shot are shot, can automatically by
The set of frequency for being used to eliminate 50 hertz of Hz noises of first imaging sensor is switched to for eliminating 60 hertz of Hz noises
Set of frequency, and control the first imaging sensor for eliminate 60 hertz of Hz noises set of frequency under shooting image,
But the invention is not restricted to this.
In another example, when the image that the second imaging sensor is shot has light and dark band, to user
Display switching is used for the prompting for eliminating the set of frequency of Hz noise.In this example, when the figure that the first imaging sensor is shot
When the image that picture and the second imaging sensor are shot all has light and dark band, being shown to user now needs switching to be used for
The prompting of the set of frequency of Hz noise is eliminated, asks the user whether that switching is used for the set of frequency for eliminating Hz noise, user
It can be selected as needed.
The method of control image working sensor according to an exemplary embodiment of the present invention can also include step S106, export
The image that first imaging sensor is shot.Specifically, when the image of the first imaging sensor shooting is in the absence of light and dark
During band, the image that the first imaging sensor of output is shot in the case where being currently used in the set of frequency for eliminating Hz noise；When second
When light and dark band is not present in the image that imaging sensor is shot, the first imaging sensor of output is being currently used in elimination work
The image shot under the set of frequency of frequency interference；When there is light and dark band in the image that the second imaging sensor is shot,
Export the first imaging sensor it is another for eliminate Hz noise set of frequency under the image that shoots.
According to an exemplary embodiment of the present, the image of output is the image that the first imaging sensor is shot, second all the time
