The technical scheme of embodiment be clearly and completely described.
Fig. 1 is the schematic flow sheet of method of adjustment one embodiment of the flash lamp of the present invention.Refer to
Shown in Fig. 1, the method for adjustment of the flash lamp of the present embodiment includes:
S11: obtain the current distance between camera lens and the object to be shot of filming apparatus；
The embodiment of the present invention does not limit the mode obtaining described current distance, such as can use based on
The diastimeter of infrared light telemetry, specifically, the infrared light launched at camera lens position
Object through being taken is received again after launching, simultaneously the time come and gone of record infrared light, so
According to displacement formula s=v*t, (wherein s represents the twice of described current distance, and v represents infrared afterwards
The light velocity, t represents two-way time), thus working as between camera lens and the object of available filming apparatus
Front distance is the half of the product of the infrared light velocity and two-way time, i.e. s/2.
S12: current distance is compared with the distance threshold preset；
S13: trigger filming apparatus shooting according to comparative result so that the flash lamp choosing of filming apparatus

S22: judge the brightness that current environment brightness is the most corresponding less than preflashing pattern；
If the brightness that current environment brightness is corresponding more than or equal to preflashing pattern, represent filming apparatus institute
Ambient brightness to be shot meets demand, it is not necessary to opens flash lamp, then performs step S23；If working as
The brightness that front ambient brightness is corresponding less than preflashing pattern, then perform step S24～S26.
S23: without opening flash lamp；
S24: obtain the current distance between camera lens and the object to be shot of filming apparatus；
S25: current distance is compared with the distance threshold preset；
S26: trigger filming apparatus shooting according to comparative result so that the flash lamp choosing of filming apparatus

On the basis of embodiment illustrated in fig. 1, the present embodiment gathers the current environment brightness of object
It is primarily adapted for use in the shooting of dark occasion.Should be understood that in other embodiments, even if currently
The brightness that ambient brightness is corresponding more than or equal to preflashing pattern, it is possible to perform step S24～S26, with
Carry out local light filling to the object being taken in the occasion that light is brighter.
The filming apparatus of the embodiment of the present invention can be to use auto-focusing mode, it is achieved premise is shooting
Device is built-in with simulation focusing system and numeral focusing system.Simulation focusing is by the letter to image
Number carry out frequency analog filtering, choose high fdrequency component and calculate and build definition evaluation of estimate function, simulation
Focusing system uses high frequency filter, when imaging or taking pictures, filters out low frequency component, takes out height
Frequency component, and when focusing, only have full frame focusing window, can only the focusing of whole screen.Numeral focusing is
By the signal of image is carried out high and low frequency digital filtering, choose high fdrequency component and low frequency component
Calculating and build definition evaluation of estimate function, numeral focusing system uses high frequency filter and low frequency filtering
Device, in shooting or when taking pictures, it is judged that high frequency, the number of low frequency, takes high frequency, low frequency numerical value
High point, and have two focusing window when focusing, one is full frame focusing window, another be
The focusing window that the middle of full frame focusing window is less, this focusing window can be big by software design patterns
Little, it is achieved to focus more accurately.Both differences are that the difference of sharpness evaluation function,
So-called sharpness evaluation function refers to: filming apparatus carry out imaging or taking pictures zoom lens time, right
High-low frequency weight value on each focusing position should can constitute a function curve, and this function curve
Upper existence one relative maximum peak value, the focusing position of this peak-peak corresponding is Jiao of camera head
Point, this function curve is sharpness evaluation function curve.
A kind of principle shot of focusing in employing simulation focusing system and numeral focusing system is:
During shooting, by the equidistant advance of autofocus lens or retrogressing (focusing the most continuously), often
A mobile step pitch, the mode of shooting piece image, obtain the multiple image that definition is different,
Now the quality of multiple image experienced by from obscuring clearly again to fuzzy process.
Then, the multiple image obtained is analyzed calculating the picture signal obtaining this image, right
Picture signal carries out digital filtering, obtains the high fdrequency component in figure signal, and combination algorithm calculates
Go out the definition evaluation of estimate that high fdrequency component is corresponding, by choosing suitable sharpness evaluation function, obtain
Obtain number intelligibility evaluation function curve.On the other hand, it is also possible to picture signal is simulated filter
Ripple, obtains the high fdrequency component in picture signal and low frequency component, and combination algorithm calculates high frequency division
Measure the definition evaluation of estimate corresponding with low frequency component, by choosing suitable sharpness evaluation function,
Obtain simulation sharpness evaluation function curve.
Owing to the quality of image experienced by from obscuring the most again to fuzzy process, for use
Sharpness evaluation function should present the Changing Pattern reduced the most again.Letter is evaluated according to definition
Number, obtains at least the first peak value in number intelligibility evaluation function curve and simulation definition is commented
Second peak value of valency function curve.Wherein, according to focusing needs, multiple first peak value can be chosen.
If the image definition that the second peak value is positioned at the frequency range at the first peak value place, i.e. this frequency range is maximum, will
This frequency range, as focus target, is focused.If the second peak value is not in the frequency range at the first peak value place,
Then in number intelligibility evaluation function curve, again choose the first peak value, in simulation definition evaluation
Function curve is chosen the second peak value again, until the second selected peak value is positioned at the first peak value institute
Frequency range；If until choose end the first peak value and the second peak value the most not in similar frequency bands, then with
The frequency range at the second peak value place, as focus target, is focused.
Specifically, when taking pictures or image, take suitable sharpness evaluation function, it is thus achieved that figure
The number intelligibility function curve of picture.Fig. 3 is clear in Atomatic focusing method one embodiment of the present invention
The schematic diagram of degree function curve embodiment, as it is shown on figure 3, transverse coordinate axis x is image sequence,
The position of corresponding autofocus lens, longitudinal coordinate axle y is definition values, and L1 is number intelligibility
Evaluation function curve, L2 is simulation sharpness evaluation function curve.Owing to the quality of image experienced by
Clear again to fuzzy process from obscuring, should present from little for the sharpness evaluation function used
To the Changing Pattern reduced again greatly.But, due to manual operation inevitable in focussing process,
Number intelligibility function curve L1 and simulation sharpness evaluation function curve L2 is not strict putting down
Sliding, unimodal curve, it may have multiple ghost peak.
In focussing process, along with image is from obscuring the stage clearly, number intelligibility evaluates letter
There is the first peak value a in number curve L1, and now the position of autofocus lens is x1, and simulation is clear
Degree evaluation function curve L2 peak value does not occur on x1 position, be i.e. described second peak value not
In the frequency range at the first peak value place, the most then again need to select in number intelligibility evaluation function curve
Take the first peak value, in simulation sharpness evaluation function curve, again choose the second peak value.
Occurring the first peak value b on x2 correspondence number intelligibility evaluation function curve L1, simulation is clear
There is the second peak value c in x2 position in clear degree evaluation function curve L2.Then judge that x2 frequency range is as focusing
Frequency range, so control autofocus lens movement focus, complete focusing.
The Atomatic focusing method of the present embodiment combines numeral focusing and simulation focusing, in focussing process
Only the second peak value need to be found to be positioned at the frequency range at the first peak value place, it is not necessary to obtain whole numerals clear
Clear degree function curve and simulation sharpness function curve, amount of calculation is little, uses numeral focusing than single
Or the simulation focusing time used is few, and focus target is accurate.
In the present embodiment, for the suitable sharpness evaluation function chosen, preferably it has fortune
Calculation amount is little, the overall permanence of energy response diagram picture, and existing sharpness evaluation function has two kinds: spatial domain
Sharpness evaluation function and the sharpness evaluation function of frequency domain, definition based on spatial domain evaluate letter
Number operand is relatively small, but noise immunity is poor.Sharpness evaluation function based on frequency domain utilizes image
Overall permanence, accurately but amount of calculation is bigger in focusing.The sharpness evaluation function of the present embodiment is preferred
Any one in energy gradient function, variance function, entropy function and squared gradient function.
In the present embodiment, use simulation focusing system and numeral focusing system to focus simultaneously,
In other embodiments of the invention, it would however also be possible to employ simulation focusing system and numeral focusing system
Any one focusing system is focused.
