The system comprises a lens, an image sensor, an image processor, a microprocessor, an acceleration sensor and a geomagnetic sensor, wherein the lens is connected with the image sensor through the acceleration sensor and the geomagnetic sensor respectively, and the image sensor is connected with the image processor. The method includes the steps: utilizing the acceleration sensor internally arranged in a mobile phone to detect horizontal shaking of the mobile phone to generate corresponding horizontal displacement, utilizing the geomagnetic sensor to detect the vertical shaking of the mobile phone to generate corresponding vertical displacement, then transmitting the horizontal displacement and the vertical displacement to the microprocessor, generating a correction value by the microprocessor, and processing the correction value and an image acquired by the image processor together, so that the image is clear and perfect. Compared with the prior art, the method and the system solve the problem of poor photographing effect due to shaking in mobile phone photographing.
Description
Technical field
The invention belongs to mobile phone, what be specifically related to is the anti-system and method for trembling of a kind of mobile phone photograph.
Background technology
Fast development along with mobile phone; Photographing function of mobile phone is known by the user gradually; Usually mobile phone photograph and mm professional camera special are taken pictures and are had very big difference; Because its major side emphasis is different, so the formed picture of mobile phone photograph normally do not pass through the image processing of mm professional camera special, therefore in the process of taking pictures, can occur because of the shake of user's hand produce the unsharp problem of the effect of clapping.
For camera; The anti-shake optics that is divided into when taking pictures is prevented trembling and electronic flutter-proof, and they have identical place on principle, and the both is the minute movement through the detecting of the gyroscope in camera lens camera; Pass to processor to information then, need the amount of compensation again by processor calculating.
And, also can't realize the anti-effect of trembling when camera is taken pictures at present for mobile phone, its captured photo also can't reach perfect effect.
Summary of the invention
For this reason, the object of the present invention is to provide the anti-system and method for trembling of a kind of mobile phone photograph, not have to prevent trembling the problem of effect when solving present mobile phone photograph.
For realizing above-mentioned purpose, the present invention mainly adopts following technical scheme:
The anti-system of trembling of a kind of mobile phone photograph; Comprise camera lens, imageing sensor, image processor, microprocessor, acceleration transducer and geomagnetic sensor; Said camera lens is connected with imageing sensor with geomagnetic sensor through acceleration transducer respectively, and said imageing sensor is connected with image processor.
Wherein said acceleration transducer is connected with image processor through microprocessor.
Wherein said geomagnetic sensor is connected with image processor through microprocessor.
Wherein said image processor is connected with mobile phone CPU, and mobile phone CPU is connected with memory.
In addition, the present invention also provides a kind of mobile phone photograph anti-fluttering method, comprises step:
A, acceleration transducer or geomagnetic sensor produce corresponding horizontal or vertical displacement signal according to the shake of camera lens;
B, microprocessor receive above-mentioned level or vertical displacement signal, and it is carried out computing, produce correction value;
C, image processor carry out correcting process according to the correction value of microprocessor to the picture from imageing sensor, obtain and revise the back image.
Wherein steps A comprises: acceleration transducer or geomagnetic sensor produce corresponding horizontal or vertical displacement signal according to the shake of camera lens, and imageing sensor obtains picture through camera lens simultaneously, and this picture is sent to image processor.
Wherein also comprise behind the step C:
D, mobile phone CPU will pass through the revised picture-storage of image processor in memory.
The present invention detects the horizontal jitter of mobile phone through the acceleration transducer that is built in the mobile phone; And produce the corresponding horizontal displacement, detect through the vertical hunting of geomagnetic sensor, and produce corresponding vertical displacement amount mobile phone; Afterwards level and vertical displacement amount are sent to microprocessor; Produce correction value through microprocessor, this correction value is handled with the picture that image processor obtains, produce the picture of clear perfect effect.Compared with prior art, when the invention solves mobile phone photograph, the problem of the weak effect of taking pictures that exists because of shake.

Embodiment
For setting forth thought of the present invention and purpose, will combine accompanying drawing and specific embodiment that the present invention is done further explanation below.
The present invention is through built-in acceleration transducer and geomagnetic sensor in mobile phone; Through acceleration transducer correction is responded in the horizontal jitter of mobile phone; Through geomagnetic sensor the vertical hunting of mobile phone is responded to correction; Reach the present mobile phone photograph of solution and be easy to generate shake, the problem of the weak effect of taking pictures.
See also shown in Figure 1ly, Fig. 1 is a system principle diagram of the present invention.The present invention is to provide the anti-system of trembling of a kind of mobile phone photograph; Comprise camera lens, imageing sensor, image processor, microprocessor, acceleration transducer and geomagnetic sensor; Said camera lens is connected with imageing sensor with geomagnetic sensor through acceleration transducer respectively; Said imageing sensor is connected with image processor, and said acceleration transducer is connected with image processor through microprocessor; Said geomagnetic sensor is connected with image processor through microprocessor; Said image processor is connected with mobile phone CPU, and mobile phone CPU is connected with memory.
Wherein said acceleration transducer is mainly used in to be responded to the horizontal jitter of mobile phone; And the corresponding induction of generation numerical value; Obtain the horizontal offset of mobile phone when taking pictures; Then this side-play amount is sent to microprocessor, handle, calculate the shake correction value that obtains on this direction through microprocessor; Described geomagnetic sensor is mainly used in to be responded to the vertical hunting of mobile phone; And the corresponding induction of generation numerical value; Obtain the side-play amount of the vertical direction of mobile phone when taking pictures; Then this side-play amount is sent to microprocessor, handle, calculate the shake correction value that obtains on this vertical direction through microprocessor.
The picture signal that imageing sensor is taken pictures and obtained through the camera lens collection; And this signal sent to image processor; What image processor obtained is the original picture signal of judder; Need revise the picture signal of this shake this moment according to above-mentioned level and vertical direction shake correction value, makes it revert to the effect of taking pictures under the inactive state.
The revised picture of process then correspondence sends to mobile phone CPU, and what mobile phone CPU was then corresponding shows these picture-storage in memory or directly on display screen.
See also shown in Figure 2ly, Fig. 2 is a workflow schematic diagram of the present invention.The present invention also provides a kind of mobile phone photograph anti-fluttering method, comprises step:
