American Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, abbreviation IEEE) 802.11p agreement, it is the communication protocol expanded by 802.11 standard of IEEE, is mainly used for Vehicle electronics wireless communication.
Shutter speed acquisition methods are described in detail with specifically embodiment below.These specific implementations below Example can be combined with each other, and the same or similar concept or process may be repeated no more in some embodiments.
Fig. 1 is a kind of flow chart of shutter speed acquisition methods shown according to an exemplary embodiment, the present embodiment with The shutter speed acquisition methods are applied to filming apparatus to illustrate.As shown in Figure 1, the shutter speed acquisition methods can wrap Include the following steps.
In a step 101, the relative moving speed of filming apparatus and object to be shot is obtained.
In the embodiments of the present disclosure, when filming apparatus lock object to be shot after, filming apparatus obtain automatically with wait clap Take the photograph the relative moving speed of object.
In one possible implementation, filming apparatus obtains the movement speed and object to be shot of filming apparatus respectively Movement speed, and calculate the relative moving speed obtained between filming apparatus and object to be shot.
As an example, filming apparatus obtains the movement speed of filming apparatus by velocity measuring device.
As another example, the information that filming apparatus is sent by receiving object to be shot, and waited for according to the acquisition of information Shoot the movement speed of object.
In alternatively possible implementation, filming apparatus by radar velocity measurement mode, obtain filming apparatus with wait clap The relative moving speed of object is taken the photograph, in this way, improving the acquisition efficiency of the relative moving speed of filming apparatus and object to be shot.
As an example, after filming apparatus locks shooting object, can trigger the radar velocity measurement module of filming apparatus to Object to be shot sends radar beam, when radar beam reaches the surface of object to be shot, can be reflected back toward radar velocity measurement mould Block, radar velocity measurement module obtain the Doppler frequency shift of the radar beam according to the radar beam being reflected back, and according to the Doppler Frequency displacement calculates the relative moving speed obtained between filming apparatus and object to be shot.
It should be noted that when filming apparatus remains static shooting object, then filming apparatus and object to be captured The relative moving speed of body is the movement speed of object to be shot, for example, user, which is still in roadside, holds filming apparatus shooting The vehicle travelled on road, then the relative moving speed of filming apparatus and object to be shot is the traveling speed of vehicle to be captured Degree.
When it is stationary state that filming apparatus, which is in moving condition and object to be shot, then filming apparatus and object to be shot Relative moving speed be filming apparatus movement speed, for example, user hold filming apparatus aboard shoot outside window Trees, then the relative moving speed of filming apparatus and object to be shot is the movement speed of the filming apparatus measured, wherein when When train and the filming apparatus are opposing stationary, the movement speed of filming apparatus is the movement speed of train.
When filming apparatus is in moving condition and object to be shot is also at moving condition, then filming apparatus with it is to be captured The relative moving speed of object is the absolute value of the difference of the movement speed of filming apparatus and the movement speed of object to be shot, For example, user holds filming apparatus with speed v1Mobile vehicle photographs are outside window with speed v2Mobile vehicle then shoots dress Set and be with the relative moving speed of object to be shot | v1-v2|。
In a step 102, the photosensitive coefficient of filming apparatus is determined according to ambient brightness.
In the embodiments of the present disclosure, after filming apparatus locks object to be shot, filming apparatus can detect object to be captured Ambient brightness locating for body, the photosensitive coefficient of adjust automatically filming apparatus.
It should be noted that then turn down photosensitive coefficient when detecting that ambient brightness is higher, when detecting ambient brightness When lower, then photosensitive coefficient is turned up.
In step 103, according to photosensitive coefficient and default image quality, initial shutter speed is obtained.
In the embodiments of the present disclosure, filming apparatus calculates according to photosensitive coefficient and default image quality and obtains initial shutter Speed.
When f-number is fixed, since the quality of picture depends primarily on shutter speed and photosensitive coefficient, and these are clapped Taking the photograph parameter has following influence to the quality of image.
In the case where photosensitive coefficient is constant, shutter speed is faster, and picture is darker, and it is weaker that dynamic blurs expressive force;Conversely, Shutter speed is slower, and picture is brighter, and dynamic process expression effect is better.
In the case where shutter speed is constant, photosensitive coefficient is higher, and picture is brighter, and noise is more;Conversely, photosensitive coefficient is got over Low, picture is darker, and noise is fewer.
It should be noted that photosensitive coefficient, default image quality and shutter speed are in certain relationship, when default picture matter When amount and photosensitive coefficient determine, the value of shutter speed can also determine accordingly.
At step 104, according to relative moving speed, initial shutter speed is adjusted, obtains target shutter speed.
In the embodiments of the present disclosure, filming apparatus adjusts initial shutter speed fast to target according to relative moving speed Door speed.
It should be noted that target shutter speed should be greater than initial shutter speed when relative moving speed is larger, this Sample is just avoided that the problem of subject image shot blurs.
In addition, it should be noted that, step 101 must execute before step 104, for example, step 101 can be in step It is executed before 102, can also be performed simultaneously, can also be executed after step 102 and before step 103 with step 102, It can be performed simultaneously, can also be executed after step 103 and before step 104 with step 103.
In conclusion shutter speed acquisition methods provided in this embodiment, by obtaining filming apparatus and object to be shot Relative moving speed, and the photosensitive coefficient of filming apparatus is determined according to ambient brightness, according to photosensitive coefficient and default picture matter Amount, obtains initial shutter speed, then, according to relative moving speed, is adjusted to initial shutter speed, obtains target shutter Speed can be improved the quality of the image of shooting using the target shutter speed, keep away to improve the precision of shutter speed Exempt from the image shot virtualization.

As an example, filming apparatus is by each relative moving speed being respectively adopted shooting when different shutter speeds Effect is tested, and finally obtains the corresponding optimal shutter speed adjusted value of each relative moving speed, and optimal fast according to this Door speed adjusted value, establishes the corresponding relationship of relative moving speed and adjusted value.
It should be noted that multiple relative moving speeds can correspond to an adjusted value, for example, filming apparatus with it is to be captured The relative moving speed of object is that shutter speed is 1/2000s in 18km/h-20km/h, and initially, then adjusted value is 1/ 4000s-1/2000s。
In step 302, according to adjusted value, initial shutter speed is adjusted, obtains target shutter speed.
In the embodiments of the present disclosure, filming apparatus adjusts initial shutter speed to target shutter speed according to adjusted value.
As an example, adjusted value is gear number, for example, if adjusted value is 1, then it represents that on the basis of initial shutter speed Add a gear, if adjusted value is -1, then it represents that the gear that on the basis of initial shutter speed subtracts one, even initial shutter speed is 1/30 Second, and adjusted value is 1, then target shutter speed is 1/60 second.
