Description
Technical field
The present invention relates to digital camera field, particularly the digital camera anti-shake field of taking pictures specifically is meant shooting device against shake and the method thereof of utilizing acceleration transducer in a kind of digital camera.
Background technology
In the modern life, digital camera has become the main shooting instrument of people, and in various handheld devices, also more and more embedded the digital camera functionality module, thereby digital camera functionality perfectly and portable equipment be combined togather, but careless shake causes the fuzzy problem that always allows the user have a headache of photograph when taking, and has lost a lot of fine moments.Generally use the cantilever technology that eyeglass is suspended on traditionally and make the physics shock-absorbing on the camera lens, but with high costs and volume very big can't accomplish compact.
Summary of the invention
The objective of the invention is to have overcome above-mentioned shortcoming of the prior art, provide a kind of utilize the acceleration of detecting when taking pictures judge the definition of photo whether meet user's needs, simple to operation, friendly interface, realization simply, lower, the applicable surface of stable work in work, cost utilizes the shooting device against shake and the method thereof of acceleration transducer comparatively widely in the digital camera.
In order to realize above-mentioned purpose, utilize the shooting device against shake of acceleration transducer and method thereof as follows in the digital camera of the present invention:
Utilize the shooting device against shake of acceleration transducer in this digital camera, comprise housing of digital camera and inner functional circuit, its main feature is, also include acceleration sensor chip and management control unit MCU in the described housing of digital camera, described acceleration sensor chip is connected with described functional circuit by management control unit MCU.
Utilize the acceleration sensor chip of the shooting device against shake of acceleration transducer to be the ADXL320 chip in this digital camera, the voltage simulate signal of its output is to described management control unit MCU.
Utilize the management control unit MCU of the shooting device against shake of acceleration transducer to be PIC12F675 in this digital camera.
This use said apparatus carries out anti-shake method of taking pictures, and its main feature is that described method may further comprise the steps:
(1) digital camera system is operated the unlatching camera function according to the user;
(2) system judges whether the opening speed detecting function according to setting in advance;
(3) if not, then directly carry out photograph taking and store captured photo;
(4) if then carry out the judgment processing operation whether corresponding system acceleration is fit to take pictures;
(5) if then directly carry out photograph taking and store captured photo;
(6) if not, the processing operation that then is not suitable for accordingly taking pictures;
(7) repeat above-mentioned steps (1).
The judgment processing operation whether this system's acceleration that carries out anti-shake method of taking pictures is fit to take pictures may further comprise the steps:
(1) whether the acceleration of system's detecting system when pressing shutter is within the acceleration threshold of systemic presupposition;
(2) if then return the result who is fit to take pictures;
(3) if not, then return the result who is not suitable for taking pictures.
This default acceleration threshold value of carrying out anti-shake method of taking pictures is: trunnion axis is ± 0.1G, and vertical axis is 0.9G～1.1G, and the total acceleration threshold range is 0.9G～1.1G.
This processing that is not suitable for taking pictures operation of carrying out anti-shake method of taking pictures may further comprise the steps:
(1) system prompt user digital camera has shake, and provides the selection that whether needs storage picture;
(2) user's selection is judged by system, if select storage, then directly carries out photograph taking and stores captured photo;
(3) if select not store, then directly return.
Shooting device against shake and the method thereof of utilizing acceleration transducer in the digital camera of this invention have been adopted, because the acceleration when having utilized detecting to take a picture is judged the effect clearly that the user expects that whether meets of photo, thereby make system can according to user default be easy to control take effect, simultaneously simple to operation, friendly interface; And the present invention to get implementation procedure simple, the system works stable performance, production cost is lower, applicable surface is comparatively extensive.
Description of drawings
Fig. 1 is for utilizing the circuit theory diagrams of the shooting device against shake of acceleration transducer in the digital camera of the present invention.
Fig. 2 is for utilizing the workflow diagram of the anti-shaking method of taking pictures of acceleration transducer in the digital camera of the present invention.
Embodiment
In order more to be expressly understood technology contents of the present invention, describe in detail especially exemplified by following examples.
See also shown in Figure 1, utilize the shooting device against shake of acceleration transducer in this digital camera, comprise housing of digital camera and inner functional circuit, wherein, also include acceleration sensor chip 1 and management control unit MCU2 in the described housing of digital camera, this acceleration sensor chip 2 is the ADXL320 chip, and the voltage simulate signal of its output is to described management control unit MCU2, and this management control unit MCU2 is PIC12F675; Described acceleration sensor chip is connected with described functional circuit by management control unit MCU.
In the middle of reality was used, ADXL320 was an acceleration transducer, output X
OutAnd Y
OutThe voltage simulate signal to MCU (PIC12F675), MCU is by sampling and calculate accekeration and by giving system through 12C.When taking pictures, as long as system goes to visit the validity that MCU just can obtain the value of acceleration and be judged photo.
See also shown in Figure 2ly again, this use said apparatus carries out anti-shake method of taking pictures and may further comprise the steps:
(1) digital camera system is operated the unlatching camera function according to the user;
(2) system judges whether the opening speed detecting function according to setting in advance;
(3) if not, then directly carry out photograph taking and store captured photo;
(4) if, then carry out the judgment processing operation whether corresponding system acceleration be fit to take pictures, this judgment processing operation may further comprise the steps:
(a) whether the acceleration of system's detecting system when pressing shutter within the acceleration threshold of systemic presupposition,
Should default acceleration threshold value be: trunnion axis be ± 0.1G, and vertical axis is 0.9G～1.1G, and the total acceleration threshold range is 0.9G～1.1G;
(b) if then return the result who is fit to take pictures;
