Description
Technical field
The present invention relates to a kind of periscopic zoom mobile lens, applied to have simultaneously preposition and postposition camera lens mobile phone,
Tablet computer etc. belongs to Zoom optical technical field.
Background technique
Since optical zoom can obtain the original image of high quality, details is clear, so people are attempting to incite somebody to action always
Optical zoom applications are in mobile phone.In general, the method for mobile phone Application Optics zoom have it is following several: 1. external extension formulas, Ci Zhongjing
Head volume is big, and system complex seems excessively thick and heavy when applied to mobile phone, such as Samsung Glaxy k zoom mobile phone, it is clear that do not meet
The frivolous developing direction of mobile phone.It is telescopic in 2., such as Nokia N93, such camera lens problem excessive there is also volume.With adding
The promotion of work technique, the Zoom optic lens of periscopic can accomplish small size, such as 3 Zoom Lens mirror of Asus's hawkeye generation
Head.
Chinese Patent Application No. is in " 201620466129.6 ", and periscopic zoom lens is just for postposition camera lens
Zoom.
Above-mentioned zoom lens is all optical zoom have been carried out just for rear camera, and people are for certainly at present
The demand of bat is also higher and higher, not only can be with zoom viewfinder range if optical zoom is added in preposition camera lens, but also can be with
Realize that background blurring to make to take theme prominent.It is background blurring that preposition double additions taken the photograph also can use algorithm process progress, but deposits
In the situation of limb recognition inaccuracy, mobile phone influences the effect of imaging.
Summary of the invention
The present invention proposes a kind of periscopic change aiming at the problem that above-mentioned periscope type lens cannot achieve front and back optical zoom
Burnt mobile lens realize that front and back camera lens all can optical zoom.
The technical solution that the present invention solves technical problem is:
A kind of periscopic zoom mobile lens, characterized in that the camera lens include it is preposition before fix before fixed group, postposition group,
Prism group, zoom group, compensation group, rear fixed group and imaging sensor；Group coaxial arrangement is fixed before fixed group and postposition before preposition,
And optical axis is vertical with the optical axis of the zoom group of coaxial arrangement, compensation group and rear fixed group；Imaging sensor is arranged at latter fixed group
Behind, for receiving image；
The prism group includes front-reflection prism and back reflection prism, can be moved in the direction perpendicular to zoom group optical axis
It is dynamic；
When mobile prism group makes front-reflection prism centers and zoom group optical axis coincidence, imaging sensor is at preposition preceding fixation
The picture of group front object；When mobile prism group makes back reflection prism centers and zoom group optical axis coincidence, system is at fixed before postposition
The picture of group front object.
The prism group includes front-reflection prism and back reflection prism, and two prisms are setting up and down and relative position is fixed, and two
Reflecting prism is the identical right-angle prism of size, and a right-angle surface of two reflecting prisms is parallel, and another right-angle surface is coplanar.
Beneficial effects of the present invention: the present invention makes image by the preposition reflecting prism and back reflection prism of mobile prism group
Sensor can also make imaging sensor at the object of group fixed before postposition front at the picture of the object of preposition preceding fixed group front
Picture realizes front and back optical zoom.
Detailed description of the invention
Fig. 1 is a kind of periscopic zoom mobile lens of the present invention, wherein the schematic diagram before preposition when fixed group work.
Fig. 2 is a kind of periscopic zoom mobile lens of the present invention, wherein the schematic diagram before postposition when fixed group work.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
As shown in Figs. 1-2, a kind of periscopic zoom mobile lens, the camera lens include fixation before preposition preceding fixation group 1, postposition
Group 2, prism group 3, zoom group 4, compensation group 5, rear fixed group 6 and imaging sensor 7；It is fixed before fixed group 1 and postposition before preposition
2 coaxial arrangement of group, and optical axis is vertical with the optical axis of the zoom group 4 of coaxial arrangement, compensation group 5 and rear fixed group 6.Imaging sensor
7 are arranged in behind rear fixed group 6, for receiving image.
The prism group 3 includes front-reflection prism 3-1 and back reflection prism 3-2, and two prisms are setting up and down and relative position
Fixed, two reflecting prisms are the identical right-angle prism of size, and a right-angle surface of two reflecting prisms is parallel, and another right-angle surface is total
Face, prism group 3 is in the direction movement perpendicular to 4 optical axis of zoom group.Zoom group 4 can be moved with compensation group 5 along optical axis direction.
The course of work
As shown in Figure 1, the schematic diagram for the present invention before preposition when fixed 1 work of group.
It is preceding when prism group 3 moves up and down reflecting surface center and the optical axis coincidence of zoom group 4 of front-reflection prism 3-1
Fixed group 1 and front-reflection prism 3-1 starts to work before setting.By the position change system for moving zoom group 4 and compensation group 5 along optical axis
The size of system focal length, plays the role of zoom.At this point, light passes sequentially through preposition preceding fixed group 1, front-reflection prism 3-1, zoom group
4, compensation group 5 and rear fixed group 6, are imaged on imaging sensor 7.
As shown in Fig. 2, schematic diagram when working for group 2 fixed before postposition of the present invention.
When prism group 3 is moved to reflecting surface center and the optical axis coincidence of zoom group 4 of back reflection prism 3-2, before postposition
Fixed group 2 and back reflection prism 3-2 starts to work；It is burnt by the position change system for moving zoom group 4 and compensation group 5 along optical axis
Away from size, play the role of zoom.At this point, light passes sequentially through fixed group 2, front-reflection prism 3-2, zoom group 4, benefit before postposition
Group 5 and rear fixed group 6 are repaid, is imaged on imaging sensor 7.
Fixed group 2, zoom group 4, compensation group 5 and rear fixed group 6 all can be single before fixed group 1, postposition before preposition
Mirror, compound lens, single compound lens or plural compound lens are constituted.Front-reflection prism 3-1 and back reflection prism 3-2 can distinguish
It is replaced with plane mirror, replaces position at the reflecting surface of reflecting prism.
Fixed 2 front of group is separately added into optical filter before preposition preceding fixed group 1 and postposition, realizes the increasing to visible light wave range
Thoroughly and to infrared band by image quality can also being made to be improved.
