Description

A kind of method and camera module device for improving camera module super large visual angle
Technical field
The present invention relates to field of photography, more particularly to a kind of method and shooting for improving camera module super large visual angle Die set.
Background technology
At present, it is the requisite function of the smart machines such as mobile phone, notebook that shooting is taken pictures.Wherein, camera module conduct Support that smart machine realizes the device of shooting camera function, with the use requirement of user, be also continuously updated and improving.It is right Many in the improvement project of existing camera module, such as CN106131380A discloses a kind of integrated camera module, its It is assembled by camera lens, IC-CUT bases, chip, PCB change-over panels, the upper and lower vertical stratification of adapter;To improve camera module Production qualification rate, reduce production cost, make product tend to modularity, and for improving product image property and stability; CN106060365A discloses a kind of camera module, including carries seat, the voice coil motor being arranged on above the load seat, is socketed in institute State the camera lens on voice coil motor, the wiring board being arranged on below the load seat and the sensitive chip being arranged on the wiring board; The wiring board includes the main line being arranged on hard wiring board and the paving circuit being arranged on the load seat, the main line It is connected with each other with paving circuit;By the way that the circuit part in former hard wiring board is extended on load seat, using in load seat It is upper to connect up to improve camera module wiring situation electromagnetic environment, improve camera module image quality.
Although existing camera module, the renewal for being attempt to the shooting performance by supporting higher pixel and software is debugged Etc. realizing the continuous lifting of its performance;But in actual user feedback, the visual angle of camera module all very little always, this It is that those skilled in the art expect always improved defect.
It is used for wide viewing angle all very littles of the camera module of smart machine, such as visual angle of cell-phone camera module in prior art Even 90 ° cannot be surmounted.For example shown in Fig. 1-3, wherein, Fig. 1 is for the cell-phone camera module of prior art and by shooting object A kind of schematic diagram of position relationship, Fig. 2 is the cell-phone camera module and another kind of position relationship by shooting object of prior art Schematic diagram, Fig. 3 is a kind of cell-phone camera module after improvement and the position relationship schematic diagram by shooting object;Black vertical post Body is subject, and black round dot is the location point of cell-phone camera module.Can be obtained by analysis:Such as Fig. 1, visual angle is 60 ° Cell-phone camera module, it can only photograph the half of waddy in location point A;And want using the cell-phone camera mould with same view angle Group photographed whole waddy, then mobile phone camera module must be moved on to farther B location point, and such as Fig. 2 is needed moved at least into twice Remote distance, so obtained imaging effect will be deteriorated;Such as Fig. 3, it is desirable to which continuation photographed whole waddy in location point A, just must The bigger cell-phone camera module in visual angle must be used, the use of visual angle is about 100 ° of cell-phone camera module corresponding to shown in Fig. 3, Whole wooden stick can be photographed.Further, Fig. 1 and Fig. 3 is contrasted, for the cell-phone camera module in same position point A, visual angle Bigger, the scenery of shooting is more, and the final shooting effect for presenting is also better.
Therefore, a kind of method and/or device for improving camera module super large visual angle, is urgently to be resolved hurrily at present.
The content of the invention
It is an object of the invention to provide a kind of method and camera module device for improving camera module super large visual angle, By a kind of method and the improvement according to the method to camera module structure, such that it is able to effectively increase regarding for camera module Angle and more preferably shooting effect can be obtained.
To achieve these goals, the technical scheme is that:
A kind of method for improving camera module super large visual angle, including:The camera lens of camera module is protruded from into machine around camera lens Component.
Further, the part for being shaped as spheroid of the camera lens, is specially cut with the tangent plane perpendicular to bulb diameter. In the case of tangent plane size identical, i.e., in the case of the rear dress face area identical of camera lens, in allowed limits, using less A part for the spheroid of diameter is favourable.
Further, the camera lens protrudes from the thickness of camera lens surrounding mechanics part and is at least the half of camera lens gross thickness.It is excellent Elect as, more than 2/3rds of camera lens gross thickness.The gross thickness of the camera lens is between the most wide location point in camera lens front and back end Distance.Most preferably, the rear dress face of the camera lens is located at the front side of the camera lens surrounding mechanics part, i.e., described camera lens protrudes completely In camera lens surrounding mechanics part,
A kind of camera module device, including camera lens, camera lens surrounding structure part and driving means;Wherein, the camera lens surrounding structure Part located at the front side of the driving means, located at the inside of driving means around driving means and camera lens tie by the camera lens The axis of component extends to the front side of camera lens surrounding structure part, presents the forwardly convex shape in camera lens surrounding structure part of camera lens State.
Further, the part for being shaped as spheroid of the camera lens, is specially cut with the tangent plane perpendicular to bulb diameter. In the case of tangent plane size identical, i.e., in the case of the rear dress face area identical of camera lens, in allowed limits, using less A part for the spheroid of diameter is favourable.
Further, the camera lens protrudes from the thickness of camera lens surrounding mechanics part and is at least the half of camera lens gross thickness.It is excellent Elect as, more than 2/3rds of camera lens gross thickness.The gross thickness of the camera lens is between the most wide location point in camera lens front and back end Distance.Most preferably, the rear dress face of the camera lens is located at the front side of the camera lens surrounding mechanics part, i.e., described camera lens protrudes completely In camera lens surrounding mechanics part,
Further, the outward flange of the front side of the driving means is conformed with.Preferably, the projection extend forward most before End is concordant foremost with the camera lens, or is slightly ahead of the camera lens foremost.Being disposed to of the projection avoids The abrasion of camera lens.
Further, the bottom of the driving means is provided with bracing frame, preferably in the sidepiece rearward of the bottom of driving means Position arranges support frame as described above.
Further, the visual angle of the camera module device is 168.8 ° ± 3 °.
In fact, generally, by camera lens be set to it is forwardly convex in the state of camera lens surrounding structure part when, finally The camera angle of the camera module for obtaining can reach 180 °, it is contemplated that camera lens in actual use can protection Problem, the outermost peripheral in the front side of driving means arranges projection, although slightly hinder maximum visual angle to a certain extent Edge, but the angular field of view of ± 3 ° of 168.8 ° for being finally reached is in actual applications enough, especially compared to Prior art, in same state with the conditions of, the effect of shooting and the visual field are all better.
