Description
[technical field]
The invention relates to a kind of stereo image-pickup digital-code camera module, especially about a kind of stereo image-pickup digital-code camera module that can focus automatically.
[background technology]
Along with Development of Multimedia Technology, digital camera, video camera more and more is consumers in general's favor, at people's logarithmic code camera, when video camera is pursued miniaturization, its quality of image of shooting object is had higher requirement, people not only are confined to watch bidimensional image, and wish and the same time to watch object with multi-angle, promptly wish to see the stereopsis of object, along with more and more being subjected to consumers in general, mobile phone welcomes simultaneously, also because mobile phone portable light and handy, the cause that is convenient for carrying, people wish by this digital-code camera module is installed in mobile phone, thus the stereopsis of photographed at any time.
Existing photograph and imaging system only can make the user obtain bidimensional image, for bidimensional image, only need single view just can realize.It adopts usually a camera is placed a fixed position, writes down the image of object then by egative film in the camera or electronic sensor.Yet people's vision be have relief, thereby human brain can produce a stereopsis with additional depth size of two image combination results.In recent years, camera and electronic sensor have designed so that people pick up bidimensional image and have reconfigured then so that produce a stereopsis with depth elements.
And existing stereo imaging system is to take object from different perspectives respectively to obtain some bidimensional images by two cameras, the common relative fixed of this two camera, after some bidimensional images of object are reconfigured, position relation by two cameras, the combination image of relevant these some bidimensional images is that stereopsis can be learnt, yet, this stereo imaging system needs two and comprises lens combination respectively, the camera body of sensing component, carry inconvenience, and this system is can't be in the time of sensing image should many images synthetic to be produced stereopsis and is shown to the user simultaneously and watch its stereopsis effect, and when imaging, can't adjust distance between two sensing components automatically, be easy to generate parallax for the object of different object distances.
A kind of having now can be handled the generation stereopsis with many images fast and easily simultaneously, can eliminate simultaneously the system of parallax, as announce in the United States Patent (USP) the 6th on April 15th, 2003,549, No. 650 disclose, it provides many eye shadows as sensing apparatus, these many eye shadows can show 3-dimensional image as sensing apparatus in the sensing image time, adjust imaging system to reach the optimal imaging effect according to shown stereopsis in good time, please refer to Fig. 1, it comprises two image sensing optical system 6701a and 6701b, an image synthesizing device (figure does not show), be used for and will synthesize a stereoscopic image signals by many signal of video signal of the object of this many Image sensor apparatus sensing, an image display (figure does not show) is used to show by the synthetic stereoscopic image signals of this image synthesizing device.Image sensing optical system 6701a and 6701b are arranged side by side and are separated by a basic spacing L who with starting point O1 is the center, it comprises imaging lens group 6702a and 6702b respectively, charge-coupled device (Charge Coupled Device as image sensor, call CCD in the following text) 6703a and 6703b, object 6904 places starting point O1 distance to be the position of Z, and many eye shadows are adjusted θ as sensing apparatus by the spacing L that changes two sensing optical system 6701a and 6701b
LMThereby the size of angle is carried out sensing and by this mode parallax is reduced to zero the object of different distance Z.
Though these many eye shadows can be realized simultaneously will these many images syntheticly producing stereopsis and seeing the 3-D effect of this stereopsis simultaneously so that adjust this imaging system sensing the time in display device as sensing apparatus, but it can only be by manual control θ
LMSize, inconvenient operation, these many eye shadows are applied in many cameras as the design department of sensing apparatus in addition, and its volume is bigger, can't be installed on mobile phone inside.
In view of above shortcoming, be necessary to provide a kind of easy to operate, can focus automatically, volume is less and can place the stereo image-pickup digital-code camera module of mobile phone inside.
[summary of the invention]
The object of the present invention is to provide a kind of easy to operate, can focus automatically, volume is less and can place the stereo image-pickup digital-code camera module of mobile phone inside.
Stereo image-pickup digital-code camera module of the present invention, it comprises two image-taking devices, an installing plate and an image compositor, described two image-taking devices are arranged at interval, comprise imaging lens group and image acquiring unit respectively; Described installing plate comprises a pars intermedia and both ends, and two image-taking devices are individually fixed in its both ends; The bidimensional image that described image compositor picks up image-taking device synthesizes a stereopsis; Described stereo image-pickup digital-code camera module also comprises an automatic focusing mechanism, a supporting component and two drive units, described automatic focusing mechanism is positioned on the pars intermedia of installing plate, the pars intermedia of described supporting component and this installing plate is affixed, described two drive units are arranged at respectively between two angles that the both ends of installing plate and supporting component form, described drive unit is according to the feedback signal of automatic focusing mechanism, thereby the angle of adjustment installing plate both ends and supporting component is adjusted the position of image-taking device.
