Description
Technical field
The utility model is related to mobile phone camera field, specially a kind of Mobile phone automatic focusing camera head.
Background technology
The digital camera functionality of mobile phone refers to whether mobile phone can be clapped by built-in or external digital camera
Static images or short-movie shooting are taken the photograph, as a new additional function of mobile phone, the digital camera functionality of mobile phone has obtained rapidly
Development.With the raising of camera pixel, shooting effect also becomes closer to traditional card camera even low side list reverse phase
Machine.
Mobile phone camera be divided into it is built-in with it is external, built-in camera refers to camera in interior of mobile phone, more convenient.External hand
Machine is connected by data line or mobile phone lower interface with digital camera, to complete all shooting functions of digital camera.It is external
The advantages of digital camera, is that the weight of mobile phone can be mitigated, and external digital camera is light-weight, easy to carry, application method
Simply.
The performance of the digital camera of mobile phone in developing stage should be also at the primary stage, and only individual handset images
Headband has optical zoom function, but major part is owned by Digital Zoom function.It is nevertheless believed that with mobile phone digital camera function
Development, the mobile phone with optical zoom also can be listed gradually.In addition to this, the digital camera functionality of mobile phone includes mainly that shooting is quiet
State image, continuous shooting function, short-movie shooting, camera lens is rotatable, automatic white balance, built-in flash etc..The shooting function of mobile phone
It is to have direct relation with its screen material, the resolution ratio of screen, camera pixel, camera material.
Optical zoom is generated by the position of camera lens, object and focus tripartite changes.When imaging surface is in water
Square to movement when, vision and focal length will change, and farther scenery becomes apparent from, and people's perceptual image object is allowed to pass
Into feeling.It is clear that change visual angle, necessarily there are two types of methods, and one is the focal lengths for changing camera lens.With if photography come
It says, here it is optical zooms.Change the focal length of camera lens by changing the relative position of each eyeglass in zoom lens.It is another
Exactly change the size of imaging surface, i.e., for the diagonal line length of imaging surface in digital photography at this moment, this is just called Digital Zoom.
Actually there is no the focal lengths for changing camera lens for Digital Zoom, change visual angle simply by the cornerwise angle of imaging surface is changed,
To produce the effect of " being equivalent to " lens focus variation.
