Specific embodiment
The present invention provides a kind of mobile terminal photographic method and system, to make the objectives, technical solutions, and advantages of the present invention
Clearer, clear, the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that this place is retouched
The specific embodiment stated is only used to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, Fig. 1 is the flow chart of mobile terminal photographic method preferred embodiment provided by the invention, as schemed institute
Show, the described method comprises the following steps:
Step S100, judge whether the camera of mobile terminal is activated, if it has, then obtaining the acceleration of mobile terminal
And angular speed；
Step S200, when the acceleration is not above acceleration rate threshold and the angular speed is not above angular speed threshold
When value, control camera is taken pictures, and saves corresponding picture.
Above-mentioned steps are described in detail below with reference to specific embodiment.
In the step s 100, judge whether the camera of mobile terminal is activated, if it has, then obtaining adding for mobile terminal
Speed and angular speed.Specifically, the mobile terminal is the terminals such as mobile phone, tablet computer, handheld device.When mobile terminal is taken the photograph
When being activated as head, the acceleration and angular speed of mobile terminal is detected.For example judge the shoot button of mobile terminal whether by point
It hits, if being clicked, shows to start camera.
In practical application, can by detect mobile terminal shoot button whether be clicked judge camera whether by
Starting, if it has, then the acceleration value of mobile terminal is detected by the acceleration transducer that mobile terminal carries, by mobile whole
The magnitude of angular velocity of the included gyro sensor detection mobile terminal in end.
About acceleration value and magnitude of angular velocity, referring specifically to Fig. 2, Fig. 2 is the mobile terminal side of taking pictures provided by the invention
The schematic diagram of acceleration and angular speed in method.By taking mobile terminal is mobile phone as an example, the acceleration transducer and gyro of mobile phone
Instrument sensor.Acceleration transducer detects X, the acceleration information A (ax, ay, az) in tri- directions Y, Z, gyro sensor
The angular speed R (r, y, p) in three directions is detected, specific direction is as schematically shown in Figure 2.Therefore, user is handshaking causes mobile phone to be trembled
Dynamic fuzzy situation of taking pictures, can be obtained, i.e. acceleration A and angular speed R two by acceleration transducer and gyro sensor
A variable.
In the step S200, when the acceleration is not above acceleration rate threshold and the angular speed is not above
When angular speed threshold value, control camera is taken pictures, and saves corresponding picture.Specifically, when the acceleration is less than or waits
When acceleration rate threshold, and when the angular speed is less than or equal to angular speed threshold value, control camera completion is taken pictures, preservation pair
The picture answered.
Setting about threshold value, it is preferable that before the step S100 further include:
S90, under dark-state environment, hold mobile terminal take pictures against ISO12233 graph card, until photographing image clearly
When, acceleration value and magnitude of angular velocity at this time is read, the acceleration threshold values and angular speed threshold value of energy blur-free imaging are respectively set as.
Specifically, on how to set acceleration A threshold values A ' and angular speed R threshold values R ', so that it is clear to make to take pictures
Imaging, specifically, light is darker, and hand shaking causes the influence of image blur bigger, if in the hand shaking of setting under dark-state light
Take pictures and do not obscure under degree, then other brighter environment under identical degree of jitter can blur-free imaging, so A and R valve
Value setting is as follows: dark-state is bright: 10 lux；Graph card: ISO12233.Photographic method: hand holds mobile phone against ISO12233 graph card
It takes pictures, can receive until photographing image definition, read acceleration value A ' (ax ', ay ', az ') and angular speed at this time
Value R ' (r ', y ', p ') data, it is set separately as the hand shaking acceleration threshold values and angular speed threshold value of energy blur-free imaging.
In practical application, reading the acceleration value A1 of sensor when user clicks shoot button using camera application
With magnitude of angular velocity R1, judges that current A1 and R1 meet the jitter conditions for executing movement of taking pictures, i.e. A1≤A ' and R1≤R ', meet
Then enter picture-taking imaging system completion to take pictures and save photo.
Preferably, the step S200 further include: when the acceleration is greater than greater than acceleration rate threshold or the angular speed
When angular speed threshold value, the duration that statistics shoot button is clicked, judge whether the duration is more than time threshold, if
Be it is yes, then control camera and take pictures, save corresponding picture.
Specifically, in order to avoid prevent it is overdue hit shoot button and be unable to satisfy always photographical condition enter judgement extremely follow
Ring sets a safety time T, when clicking shoot button delay t >=T, can enter picture-taking imaging system completion and take pictures
Movement.That is, as A1 > A ' or when R1 > R ', for prevention user accidentally touching shoot button, after statistics clicks shoot button event
Duration t takes pictures into picture-taking imaging system completion as t >=T, saves picture.About T value specifically can as needed into
Row is arranged, for example 0.5s.
Mobile terminal photographic method provided by the invention is held under harsh environment (10lux dark-state) by grasping
It takes pictures, finds the unambiguous manual threshold values of imaging, this threshold values and manual case when actually taking pictures are compared, hand shaking is worked as
Degree is weaker than this threshold values, then can assert that clapped photo must be situation, completes imaging of taking pictures, saves clear picture.Method
Simple and easy, the picture that every preservation of taking pictures is completed under the premise of not increasing hardware cost is all clearly to require.
