And under the premise of exploitativeness, the explanation of following methods invention will focus on step content and non-hardware.
Fig. 1 is the functional block diagram of an embodiment of optical anti-shake circuit of the present invention.Optical image stabilising arrangement 10 (or
Referred to as optical anti-shake circuit) one of function be according to (the reaction phase of Vibration induction signal caused by Shock inductor 30
The vibration degree of machine module), to control the position that voice coil motor 40 correspondingly adjusts camera lens, with compensation because camera model shakes
Caused camera lens offset.Shock inductor 30 may, for example, be gyroscope, senses the vibration of camera model and generates angle speed
Spend signal.Angular velocity signal after 130 pairs of integrator digitlizations (being converted by ADC 120) carries out integral operation, obtains corresponding phase
The angular deviation θ of machine module vibration degreegyro；On the other hand, driving inductor 50 (such as a hall sensor) incudes sound
Changes of magnetic field caused by coil motor 40 (reaction voice coil motor 40 to the drive volume of camera lens, that is, the displacement of reaction shot) and
Driving inductive signal S ' is generated, this driving inductive signal S ' (drives inductive signal S) after being converted to number format via ADC190,
Noise is filtered out via filter 180, then the mapping table by converting unit 160 with reference to mapping circuit 170 is converted to corresponding camera lens
The angular deviation θ of displacementhall.Adder 135 calculates angular deviation θgyrO and angular deviation θhallDifference
θerror(=θgyro-θhall), proportional integral differential (proportional integral and differential, PID) control
Device 140 processed is again according to this difference θerrorThe size of driving signal V when the control driving voice coil motor 40 of motor drive circuit 150
(such as size of current) makes voice coil motor 40 that camera lens are moved to target position in a stepwise fashion, to avoid camera lens primary
It is generated in significantly moving in place and apparent shakes (damping).It note that due to difference θerrorOr angular deviation θgyro
System according to Shock inductor 30 Vibration induction signal and generate, so can be considered that vibration in optical image stabilising arrangement 10 is mended
Repay signal；Furthermore in some cases, if camera lens is generated in the process of moving to shake unobvious, optical image
Stabilising arrangement 10 can omit proportional plus integral plus derivative controller 140, and motor drive circuit 150 directly couples adder in the case
135, and direct basis difference θerrorTo drive voice coil motor 40.
Driving inductor 50 is easy to be influenced by operating environments such as temperature and to drive inductive signal S with biggish
Noise, the first purpose of filter 180 are to filter out such noise.Fig. 2 is the office of an embodiment of filter of the invention
Portion's circuit diagram, the purpose of this circuit are to filter out in continuous signal because the signal caused by noise acutely changes.Three delays are single
For member 181,182 and 183 respectively by the frequency cycle T of one system of signal delay, adder 184 couples three delay cells, meter
Calculate the difference DELTA S of signal S [k-1] and signal S [k-2]1And the difference DELTA S of signal S [k] and S [k-1]2(k is integer, is represented
Time index):
ΔS1=S [k-1]-S [k-2] (1)
ΔS2=S [k]-S [k-1] (2)
Later, comparator 185 is by Δ S1With Δ S2Absolute difference abs (Δ S1-ΔS2) compared with a critical value, such as
Fruit Δ S1With Δ S2Absolute difference be greater than critical value, then it represents that the value of signal S [k-1] and the value of signal S [k] and signal S [k-
2] value difference enables multiplexer away from excessive (that is, signal S [k-1] may be noise), the control signal of the output of comparator 185 at this time
186 selection signal S [k-2] output, to filter out noise signal S [k-1]；And if Δ S1With Δ S2Absolute difference no more than facing
Dividing value, then the output of comparator 185 control signal, enables 186 selection signal S [k-1] of multiplexer export.Therefore, 180 pairs of filter drives
Dynamic continuous three signal of the inductor 50 after Analog-digital Converter is made comparisons, and is added and subtracted wherein only needing to use adder 184
It operation and is compared using comparator 185, the electricity of circuit area and operation time is occupied without using multiplier etc.
Road, therefore the cost of filter 180 can be reduced and increase efficiency.
Drive inductor 50 driving inductive signal S after filtering become filtering signal S_F, this filtering signal S_F again by
Converting unit 160 is converted into angular deviation θ with reference to the mapping table of mapping circuit 170hall.Drive the driving of inductor 50
Inductive signal S and angular deviation θhallCorresponding relationship measure and be stored in the mapping table of mapping circuit 170 in advance, convert
Unit 160 is with reference to mapping table and uses interpolation method and/or extrapolation, and driving inductive signal S is converted to corresponding angle offset
Measure θhall.For example, converting unit 160 first judges that filtering signal S_F is located at the section [S of mapping circuit 170map,Smap+1],
Wherein SmapAnd Smap-+1Respectively correspond angular deviation θmapAnd θmap+1, and the slope in this section is ratiomap；Then angle offset
Measure θhall=(S_F-Smap)·ratiomap+θmap。
However, it is excessive to drive the output of inductor 50 to be influenced by environmental factors such as temperature sometimes, and cause its driving sense
There is large-scale unreasonable output valve in induction signal S, filter 180 can be believed with reference to the driving of motor drive circuit 150 at this time

When the driving inductive signal S of dynamic inductor 50, multiplexer 165 and 175 is according to control signal Ctrl (being issued by processing unit 110)
Choosing filtering signal S_F and corresponding mapping table makes converting unit 160 be converted to angular deviation θ hall accordingly, then compares
Example integral-derivative controller 140 can be according to above-mentioned mechanism control motor drive circuit 150；On the other hand, work as motor drive circuit
When 150 driving voice coil motor 40, multiplexer 165 and 175 is according to control signal Ctrl selection driving signal V and corresponding mapping table
Converting unit 160 is set to be converted to signal v2h accordingly, filter 180 filters out the big model of signal S with reference to this signal v2h at this time
The unreasonable output valve enclosed.That is the same converting unit 160 can be used to convert and drive in optical image stabilising arrangement 10

Answer the large-scale unreasonable output valve in the driving inductive signal S of device 50.Signal v2h [k] is the converted list of driving signal V
Signal after 160 conversion of member.Input summer 188, adder 188 are counted simultaneously by signal S [K] and signal v2h [k] by delay
It is abs (S [k]-v2h [k]) that calculation, which obtains its absolute difference,.Comparator 189 again compares this absolute difference with default value, if
Absolute difference is greater than default value, and unreasonable output valve occurs in the driving inductive signal S represented at this time, then filter 180 skips over
This section of unreasonable output；Opposite, if absolute difference is not more than default value, driving inductive signal S at this time is represented to close
The output valve of reason, then filter 180 can further be filtered driving inductive signal S and (use filtered electrical shown in Fig. 2
Road).
The thin portion circuit diagram of proportional plus integral plus derivative controller 140 is as shown in Figure 4.Margin of error e (angular deviation i.e. above-mentioned
Difference θerror) after the delay of three delay cell 141,142 and 143, by multiplier 145 by the margin of error e after delay
It is multiplied by PID coefficient (being stored in buffer 147), adder 146 is again by the output of multiplier 145 and previous control variable
U [k-1] is added, and control variable u [k] that finally can be proper time is as follows:
U [k]=u [k-1]+k1e [k]+k2e [k-1]+k3e [k-2] (3)
Motor drive circuit 150 adjusts the size (i.e. driving force) of its driving signal V according to control variable u, wherein PID system
Number k1, k2 and k3 and original PID coefficient (kp, ki, kd) have following transformational relation:
Above-mentioned transformational relation can be come out by the original PID derivation of equation, and PID most basic principle formula is expressed as follows:
After equation (5) is converted to discrete time mode, it can obtain:
Equation (6) are adjusted as follows:
The transformational relation of equation (4), which is applied to after equation (7) arranges again, can obtain equation (3).Utilize conversion
PID coefficient k1, k2 and k3 afterwards does operation, enables proportional plus integral plus derivative controller 140 of the invention with shown in Fig. 4 simple
Circuit is completed, and can be exempted complicated integral and be differentiated.
In conclusion optical image stabilising arrangement 10 of the invention has the characteristics that circuit is simple, and through appropriate

Camera model i.e. by photographic subjects object when, alignment target object and image sensor 20 have generated the shadow of object to camera lens at this time
As (step S610).Later, processing unit 110 analyzes the image of object and generates the angular speed letter of corresponding object displacement
Breath (degree of displacement of object is also converted to the vibration degree of camera model) (step S620), this angular velocity information, that is, generation
Moving condition of the table object in shooting process.Then, integrator 130 integrates this angular velocity information, and obtains corresponding mesh
The angular deviation that level is moved is marked, and proportional plus integral plus derivative controller 140 is according to this angular deviation and driving inductor 50
The difference of angular deviation determine camera lens eccentric traveling distance (step S630).Then motor drive circuit 150 is again according to mirror
Head eccentric traveling distance driving voice coil motor 40 is to adjust camera lens, that is, motor drive circuit 150 is more according to camera lens eccentric traveling distance
Voice coil motor 40 is adjusted to the drive volume (step S640) of camera lens, makes the movement tendency of camera lens and the displacement trend one of object
It causes, to obtain clearer object image.The process of Fig. 6 can be with the optical anti-shake above-mentioned of optical image stabilising arrangement 10
