Abstract
The present invention is a kind of camera auto-focusing system based on recognition of face, including face recognition module, core processing module, camera link block, image output module, screen identification module；Camera link block is responsible for and camera is attached, and obtains the real-time image information of camera lens and image information is passed to core processing module；Face recognition module is responsible for analyzing image information, captures face information and incoming screen identification module；The mark of screen identification module owner's face image, and result is passed to core processing module；Image output module is responsible for image information showing user；Core processing module is responsible for receiving the next real-time image information of camera link block transmission and identifies information feeding face recognition module, and the information is showed user by image output module when screen identification image is incoming by the information for identifying good person's face；The present invention has the characteristics that quick, accurate, automation.
Description
Technical field
The present invention relates to a kind of camera auto-focusing systems based on recognition of face.
Background technique
The appearance of smart phone greatly enriches our life, in occupation of more and more important in our life
Status, and mobile phone self-timer is a critical function of mobile phone.But many people when using mobile phone self-timer due to that will not focus, clap
Portrait out is all very fuzzy, affects usage experience.We can by design one auxiliary camera autofocus system come
Solve this problem.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of camera based on recognition of face from
Dynamic focusing system has the characteristics that quick, accurate, automation.
The present invention is a kind of camera auto-focusing system based on recognition of face, including face recognition module, core processing
Module, camera link block, image output module, screen identification module；
The camera link block is responsible for and camera is attached, and obtains the real-time image information of camera lens and by image
Information is passed to core processing module；
The face recognition module is responsible for analyzing image information, captures face information and incoming screen identification mould
Block；
The mark of the screen identification module owner face image, and result is passed to core processing module；
Described image output module is responsible for image information showing user；
The core processing module is responsible for receiving the next real-time image information of camera link block transmission and send the information
Enter face recognition module to be identified, the information is passed through into image when screen identification image is incoming by the information for identifying good person's face
Output module shows user.
Wherein, screen identification module is identified using linear filtering algorithm image.
Wherein, face recognition module carries out recognition of face by Eigenface, captures face information.
The utility model has the advantages that
User is using the camera auto-focusing system self-timer of the present invention based on recognition of face or bat personage, phase
Machine can lock personage's head portrait automatically and focus, and the photo for taking is made not thicken due to not having focusing.Entirely
Auto-focusing process is quick, accurately.
Detailed description of the invention
Fig. 1 is the camera focusing system structure chart.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
As shown in Figure 1, the present invention is a kind of camera auto-focusing system based on recognition of face, including recognition of face mould
Block, core processing module, camera link block, image output module, screen identification module；
The camera link block is responsible for and camera is attached, and obtains the real-time image information of camera lens and by image
Information is passed to core processing module；
The face recognition module is responsible for analyzing image information, captures face information and incoming screen identification mould
Block；
The mark of the screen identification module owner face image, and result is passed to core processing module；
Described image output module is responsible for image information showing user；
The core processing module is responsible for receiving the next real-time image information of camera link block transmission and send the information
Enter face recognition module to be identified, the information is passed through into image when screen identification image is incoming by the information for identifying good person's face
Output module shows user.
Wherein, screen identification module is identified using linear filtering algorithm image.
Wherein, face recognition module carries out recognition of face by Eigenface, captures face information.
For user when being taken pictures using the present invention, core processing module obtains shot information by camera link block,
And camera lens captured information is divided into region, each region is passed to face recognition module respectively and analyzed by core processing module,
It sees whether the region has face information, will there is the region of face information to be labeled by screen identification module, pass back at core
Device is managed, core processor controls camera auto-focusing identified areas by camera link block and completes auto-focusing.It simultaneously will mark
Know region to come out by screen representation module marks, feeds back to user.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
