Description
Technical field
The present invention relates to multi-cam module, more particularly to there are the double of different size aperture to take the photograph module, it makes final one
The dark-state performance and definition of composograph lift and obtained more accurately depth information.
Background technology
With the development of science and technology, various sci-tech products it is relative in response to and give birth to, be per one Smartphone of human hand held
Universal common situation, wherein the camera included in the Smartphone is even more a main function, and also it is most of
People be even more that the camera of mobile phone accustomed to using replaces general traditional camera to go record to live and through the Smartphone
Directly share to internet.Especially, it is continuous in response to various demands and development, the specification of various related software and hardware spare and accessory parts
Evolve, therefore gradually the camera function of mobile phone accustomed to using goes to instead of the camera of major part people.
The trend of rapid growth, especially smart mobile phone are kept it is noted that being remained unchanged in current mobile phone market
Increase more swift and violent.Also because of requirement of the user for shooting quality also more and more higher, therefore, for the property of camera module
Pursuit that can be remarkable is as major mobile-phone manufacturers keen competition key technology area.In 2014, as space dragon is issued
Carry double smart mobile phones taken the photograph, camera module, which enters, double takes the photograph the epoch.For initial dual camera, its major function is
In 3D display effect and shooting ability, but pixel is too low and image quality is not high, is also significantly improved for dual camera
Space.
Therefore, the camera module development trend of smart mobile phone technically develops to dual camera, and due to intelligence
Mobile phone has strict requirements for thickness, thus must be volume be unlikely to increase too much in the case of excellent shooting is provided
Effect.In other words, can not be too high for the whole height of the camera module of smart mobile phone, so limit sensitive chip size
Can not be too big, cause imaging effect not lifted further, therefore in order to lift image quality, using the scheme of dual camera.
However, current double schemes taken the photograph scheme and use the RGB+MONO chips with pixel on the market, because algorithm will be carried out to image
Synthesis is, it is necessary to ensure the uniformity of image, using the camera lens of same size.But the definition of the pixel of dual camera is simultaneously
It is not simple addition, therefore, it is necessary in the case where not increasing cost, the double efficiency for taking the photograph module of lifting, allows user to have more
Good experience, dark-state effect is especially lifted, for strengthening Consumer's Experience important in inhibiting.
The content of the invention
It is a primary object of the present invention to provide one to have the multi-cam module of different size aperture, it makes finally to synthesize
The dark-state performance and definition of image lift and obtained more accurately depth information.
Another object of the present invention is to provide one there is the multi-cam module of different size aperture, including two
More than camera module, it be at least one monochrome (black and white) camera module and at least one colored camera module, and it arranges in pairs or groups one respectively

Module as it is double take the photograph module and absorb image at the same time when, reference images are used as using the image that color sensitive chip is absorbed, and singly
The image of color sensation optical chip intake then carries out booster action.And the camera lens light of the camera module for the monochromatic sensitive chip of arranging in pairs or groups
Circle increase, the double of the different size aperture so can be further made to take the photograph module and have more preferable dark-state effect and definition.
Another object of the present invention is to provide one there is the multi-cam module of different size aperture, wherein described two take the photograph
As the lens aperture of module is to differ size, that is to say, that the camera lens of the camera module of the monochromatic sensitive chip will be matched
Aperture is done greatly, can so ensure described image on the premise of uniformity, lifts dark-state effect.
Another object of the present invention is to provide one to have the multi-cam module of different size aperture, wherein color sensitive
Chip only filter light just can determine that color should occur where.Just because of this, it can lose some details.It is and of the invention
The monochromatic camera module aperture increase, so as in the unit interval, light-inletting quantity increase, because monochromatic sensitive chip is only to appointing
How much interested the injection light of what set point is, and without considering that what kind of the color of light is, so as to which monochromatic sensitive chip can
To capture more rich details from scene.Exactly these details allow image to become apparent from, and dark-state effect obtain it is significant
Enhancing.
Another object of the present invention is to provide one there is the multi-cam module of different size aperture, wherein being drilled through one
Algorithm ensures the problems such as focusing, depth and information of two camera module.
Another object of the present invention is to provide one there is the multi-cam module of different size aperture, wherein for realizing
The lifting of brightness and the reduction of noise under half-light.The double of the other different size aperture take the photograph module and can also lift focusing speed,

Following steps：
Shadow is absorbed by the colored camera module 30 ' and the monochromatic camera module 20 ' of the multi-cam module
Picture, wherein the monochromatic camera module 20 ' relative to the colored camera module there is larger aperture to increase light-inletting quantity；
The image that the colored camera module 30 ' and the monochromatic camera module 20 ' are respectively obtained is synthesized to obtain one
Composograph；And
The composograph after output or storage processing.
The multi-cam module is embodied as a pair of and takes the photograph module, and it is configured to that there is the colour of the color sensitive chip to take the photograph
Picture module 30 ' and the monochromatic camera module 20 ' with the monochromatic sensitive chip.It is noted that the colour is taken the photograph
As module 30 ' is different with the lens aperture size of the monochromatic camera module 20 ', in particular, although two camera modules
Lens aperture is different, but the image that absorbs respectively of two camera modules or image are consistent, such transmission having with pixel
The double of different size aperture take the photograph module lifting dark-state effect.
The monochromatic camera module 20 ' uses larger lens aperture, is obtained for the monochromatic sensitive chip intake more various
Half-tone information, can so make double final images of module of taking the photograph of the different size aperture have more preferable dark-state effect and clear
Degree.
The image that colored camera module 30 ' with the color sensitive chip is absorbed is as a reference images.Have
The image that the monochromatic camera module 20 ' of the monochromatic sensitive chip is absorbed is as an image processing auxiliary information.
Correspondingly, it is that auxiliary information handles the reference images in applying at the image when synthesizing the image, its
Described in Image compounding be using a picture splicing method.
It should be understood by those skilled in the art that the embodiments of the invention shown in foregoing description and accompanying drawing are only used as illustrating
And it is not intended to limit the present invention.The purpose of the present invention completely and effectively realizes.The function and structural principle of the present invention exists
Show and illustrate in embodiment, under without departing from the principle, embodiments of the present invention can have any deformation or modification.
