Description
Technical field
The present invention relates to the camera-shooting and recording device of a kind of multiple camera lens, the most multiple camera lenses are respectively positioned on same view direction, with many camera lenses mobile phone that smart mobile phone is main device carrier.
Background technology
In daily life, small intelligent camera device, it is widely used, its common device is smart mobile phone or drive recorder.These equipment all with
1
Individual above shooting len, for actively or automatically recording dynamic video or static image, brings great convenience to people's life, thus is used widely.
As a example by smart mobile phone, daily smart mobile phone, generally have
1
Before
1
Latter two shooting len, obtained optical image, through the process of graphic chips, is shown on the display screen in front, is stored in the storage facilities of mobile phone after confirmation.Wherein with back shooting len as main lens, the hardware index such as its resolution is usually above the auto heterodyne camera lens in front.
Due to by volumetric constraint, the shooting len often simple in construction used on such small intelligent camera device, cannot be such as functions such as high-end cameras or video camera whole realization zooms, although in the recent period, its lens construction used has been made a lot of technological improvement, but still to focus or micro-zoom lens is its primary structure, it means that the shooting len used, it is shot with video-corder visual angle and is restricted, substantially stationary or excursion is narrower.
Owing to there is the defect that visual angle is difficult to adjust in the camera lens of existing camera-shooting and recording device, and camera lens to shoot with video-corder visual angle the biggest, then content of finding a view is the widest, mean in the case of equal resolution, its detail resolution is the lowest, therefore on using, it is necessary to camera lens is shot with video-corder visual angle and makes a choice.At present, general mobile phone uses
60
° standard viewing angle arrive
90
The fixed viewpoint camera lens at the big Radix Rumicis visual angle about °, should ask viewfinder range big regardless of whether any fixed viewpoint camera lens is all difficult to meet, require that again resolution much higher sample complexity shoots with video-corder the requirement of occasion.
Currently for main lens namely the back shooting len of smart mobile phone, in addition to single-lens design, still there is multiple twin-lens to design, generally, have following several ways.
The first is to utilize the twin-lens spaced out, and realizes stereophotography function, but due to the restriction of mobile phone volume, the spacing of twin-lens is little, have impact on imaging effect, and the stereotome effect formed is unsatisfactory.
The second is to use the shorter twin-lens of spacing, shoots with video-corder identical picture simultaneously, utilizes optical chip be analyzed two groups of images merge image detail, with obtain photo sensitivity more preferably, picture that imaging effect is finer and smoother, main purpose is optimal imaging quality.
The third is to increase, on main lens side, the little shooting len of auxiliary that a resolution is relatively low, and the depth of field of this shooting len is different from main lens, can help main lens rapid focus, and main purpose is to promote image taking speed.
By with upper type it can be seen that current main flow twin-lens processing mode is all not related to the process shooting with video-corder visual angle.
And from actual demand, people are when using mobile phone photo and video or video recording, for shooting with video-corder the central area in region, usually can think that definition is inadequate after imaging, it is impossible to obtain the situation of enough details.Therefore, a lot of mobile phones are all accompanied with enlarging function
(
Be equivalent to shoot with video-corder visual angle diminish
)
, but this function is not actually based on the physics regulation of camera lens, but by the hard-wired digital amplification mode of software and graphic chips, with the later stage
PS
Processing essence no difference, actual definition improves, the most recreational.And the operating procedure of manipulation zoom function is time-consuming, it is impossible to meet the requirement quickly shot with video-corder.And the definition obtaining reality improves, it is necessary for walking close to shoot with video-corder target, is to waste time and energy, thereby increases and it is possible to limited owing to shooting with video-corder environment and opportunity, the requirement closely shot with video-corder cannot be accomplished at all.
And the zoom magnification of a zoom lens mobile phone slightly exists
2-3
Between Bei, its function is limited, and image quality is often below the tight shot with gear, the most only experimentally uses at fraction machine.
Generally, shooting len to be changed shoot with video-corder visual angle, reach to amplify the purpose of central area imaging definition, realize often through external lens cap external member, not only affected by quality and the focusing of lens jacket and cause image quality poor, and it is bothersome time-consuming to change camera lens, and can not meet equally and require that viewfinder range is big, resolution much higher sample complexity shoots with video-corder the requirement of occasion simultaneously.
Additionally, retrieval has application number

And it practice, can switch the mode of operation of before and after's camera lens by the way of inside chip control electrical switch due to existing mobile phone, it is seen that this technology uses electrical switch to replace physical switch, just has actual application value and may implement.
On the other hand, it is also possible in actual use run into and i.e. requires to retain relatively wide viewing angle area image, the situation that centering key area imaging definition is high again.Such as when clapping personage, it is possible to wish to accommodate landscape as much as possible, wish that again the details of character facial is clear.Or for a vehicle accident evidence obtaining when, i.e. intentionally get a large-scale panoramic pictures, it is the most clear to wish again certain details such as license plate number or position of collision etc..This equally will waste time and energy through repeatedly shooting with video-corder, and is difficult to ensure that video camera meeting.
Summary of the invention
For solving the above mobile phone existing shooting len defect in the existence used, the technical problem to be solved in the present invention is to provide the mobile phone of a kind of multiple camera lens, can be while shooting with video-corder wide angular range image, center area image is carried out high-resolution record simultaneously, provide a kind of mobile phone display mode helping user fast to confirm to shoot with video-corder effect the most simultaneously.
The technical solution adopted in the present invention, it is to provide a kind of many camera lenses mobile phone, including mobile phone body, internal circuit, the touch display screen in mobile phone body front, its internal circuit includes the intelligent control circuit of mobile phone, graph processing chips and storage device, there is main lens at mobile phone body back, there is auto heterodyne camera lens in front, and main lens is to shoot with video-corder visual angle to be more than
70
° wide-angle lens；
At mobile phone body back the most at least
1
Individual with main lens central area camera lens in the same direction, visual angle is shot with video-corder less than main lens in the visual angle of shooting with video-corder of this central area camera lens；
Main lens and central area camera lens gained electronic image information save as different files after interior of mobile phone processing of circuit simultaneously.
Therefore the high-resolution detailed images of its central area can while obtaining the wide-angle image that viewfinder range is bigger, be obtained.
Main lens and central area camera lens both can be zoom lens, it is also possible to being tight shot, both can also use different mode.
