Mould etc..
In embodiments of the present invention, if receiving the enabled instruction of camera, camera can be called to gather the first figure
As data, at the same time (especially in exposure), gyroscope measurement angular speed is called.
Wherein, the enabled instruction of camera refers to the instruction for starting camera, user can by clicking on camera applications, or
Person, press the enabled instruction that the modes such as the physical button specified trigger camera.
It should be noted that gyroscope be not be arranged on camera in sensor, but in mobile terminal one it is general

The high effect restored.
Reference picture 2, the step flow chart of the restored method of another view data of one embodiment of the invention is shown,
Using in the terminal, mobile terminal has gyroscope, and this method specifically may include steps of：
Step 201, gather the first view data and call the gyroscope measurement angular speed.
In embodiments of the present invention, the motion blur model according to view data, fuzzy view data can be regarded as
The synthesis that convolution algorithm adds noise is clearly done between view data and fuzzy core：
Wherein, B represents fuzzy view data, and L represents clearly view data, and K represents fuzzy core, and N represents noise,
Represent convolution algorithm symbol.
For fuzzy view data, B and N are known, and L and K are unknown, can be to fuzzy in order to obtain L
Core K is estimated.
Due to the shake of mobile terminal, same object is caused to appear on the diverse location of the first view data, so as to lead
The fuzzy of view data is caused.
As shown in figure 3, exist a bit (X, Y, Z) in object space (object space) 301, it is mobile whole due to shake
The camera at end is moved on a series of position k (k=1, k=2 ..., k=K, K are positive integer), a series of corresponding to this
Position k (k=1, k=2 ..., k=K), the point (X, Y, Z) on object space 301 is in imaging plane (image plane) 302
Upper generation volume of data point ((x1, y1), (x2, y2) ..., (xK, yK)), form shake track (motion trajectory)
303。
Therefore, fuzzy core is related to the shake of user's hand-held mobile terminal, also referred to as point diffusion track.
In embodiments of the present invention, can be by calling the gyroscope built in mobile terminal to catch the shake of mobile terminal.
Step 202, the angular speed is integrated, obtains attitude angle.
In the specific implementation, the angular speed w of gyroscope output, angular velocity integrated, and can obtain mobile terminal
Attitude angle θ.
Furthermore, the angular speed w of gyroscope output includes the angular speed w in x-axis directionx, angular speed w in y-axisy、z
Angular speed w on axlez。
To the angular speed w in x-axis directionxIntegrated, then can obtain the pitching angle theta that mobile terminal surrounds x-axis rotationx, i.e.,
θx=∫ wxdt。
To the angular speed w in y-axis directionyIntegrated, then can obtain the yaw angle θ that mobile terminal surrounds y-axis rotationy, i.e.,
θy=∫ wydt。
To the angular speed w in z-axis directionzIntegrated, then can obtain the roll angle θ that mobile terminal surrounds z-axis rotationz, i.e.,
θz=∫ wzdt。
Step 203, based on the attitude angle in described first image data location ambiguity position.
(especially exposed in the specific implementation, can be monitored when mobile terminal is gathering the first view data by gyroscope
Light time) motion change, so as to measure the change of the attitude angle of mobile terminal, the change of these attitude angles can correspond to first
Positional information in view data, as ambiguous location.
Furthermore, being multiplied for focal length and the tangent value of attitude angle when gathering the first view data, then can obtain
Ambiguous location in first view data：
pr=ditan(θ)
Wherein, prFor ambiguous location, diTo gather focal length during the first view data, θ is attitude angle.
In one embodiment of the invention, step 203 can include following sub-step：
Sub-step S11, inquiry gather focal length during the first view data.
Sub-step S12, the tangent value of the angle of pitch and the tangent value of the yaw angle are formed into attitude angle matrix.
Sub-step S13, by the focal length and the attitude angle matrix multiple, obtain the mould in described first image data
Paste position.
In actual applications, attitude angle includes pitching angle thetax, yaw angle θyWith roll angle θz, as shown in figure 4, around z-axis
Roll angle θzSensor devices with camera be in the same plane, therefore, roll angle θzChange can't be to the first picture number
According to it is fuzzy cause large effect, however, yaw angle θyWith roll angle θzChange then can be to the fuzzy production of the first view data
Raw large effect.
Therefore, in embodiments of the present invention, with pitching angle thetaxWith yaw angle θyThe fuzzy position being positioned in the first view data
Put, ignore roll angle θz, to reduce operand, processing speed is improved, meanwhile, ensure the accurate rate restored.
Wherein, prFor ambiguous location,For in the ambiguous location in x-axis direction,For in the ambiguous location in y-axis direction, di
To gather focal length during the first view data, θxFor the angle of pitch, θyFor yaw angle.
Step 204, the ambiguous location is formed into shake of the mobile terminal when gathering described first image data
Track.
In the specific implementation, as shown in figure 5, ambiguous location is the location of pixels (pixel in the first view data
Position), by location of pixels composition together, then can as mobile terminal trembling when gathering described first image data
Dynamic rail mark.
In one embodiment of the invention, step 204 can include following sub-step：
Sub-step S21, inquiry gather time for exposure during described first image data.
Sub-step S22, ambiguous location of the combination within the time for exposure, obtains the mobile terminal described in collection
Shake track during the first view data.
In embodiments of the present invention, by the ambiguous location p in time for exposure τrCombine, then can obtain gathering
During view data, the caused shake track due to the shake of mobile terminal：
Wherein,To shake track, prFor ambiguous location.
Step 205, the shake track is arranged to fuzzy core.
In the specific implementation, if the ambiguous location in shake track is more intensive, the shake track can directly be set
For fuzzy core.
If the ambiguous location shaken in track is more sparse, interpolation processing can be carried out to shake track, at interpolation
Shake track after reason is arranged to fuzzy core.
Step 206, described first image data are deconvoluted based on the fuzzy core and removes noise, obtain second
View data.
If having obtained fuzzy core, fuzzy core can be used to calculate clearly the second view data.
Furthermore, the motion blur model according to view data, the first fuzzy view data is gone with fuzzy core
Convolution simultaneously removes noise, then can obtain clearly the second view data.
It should be noted that in some cases, noise can be ignored, you can so that noise is considered as into sky.
In an example of the embodiment of the present invention, Wiener filtering can be used, based on fuzzy core to described first image
Data are deconvoluted and remove noise：
Wherein, F (L) is the discrete Fourier transform of the second view data, and F (K) is the discrete Fourier transform of fuzzy core,
F (B) is the discrete Fourier transform of the first view data, and Φ is signal to noise ratio.
Certainly, the method (i.e. Wiener filtering) of above-mentioned deblurring is intended only as example, can when implementing the embodiment of the present invention
To set the method for other deblurrings according to actual conditions, for example, Lucy-Richardson (LR), etc., the embodiment of the present invention
This is not any limitation as.In addition, in addition to the method for above-mentioned deblurring, those skilled in the art can also adopt according to being actually needed
With the method for other deblurrings, the embodiment of the present invention is not also any limitation as to this.
It should be noted that for embodiment of the method, in order to be briefly described, therefore it is all expressed as to a series of action group
Close, but those skilled in the art should know, the embodiment of the present invention is not limited by described sequence of movement, because according to
According to the embodiment of the present invention, some steps can use other orders or carry out simultaneously.Secondly, those skilled in the art also should
Know, embodiment described in this description belongs to preferred embodiment, and the involved action not necessarily present invention is implemented
Necessary to example.
