Step B2-4: judge that non-circular eyeglass has been aligned with induction chip.
Wherein, in step B1-3, when judging first edge image with second edge image alignment, step is carried out
B1-4, conversely, then carrying out step B1-1 again.In step B2-3, when judging image qualification, step B2-4 is carried out, otherwise,
Step B2-1 is carried out again.
It is to assemble the board of photographing module of the present invention in one preferably please refer to Fig. 2, Fig. 4 A, Fig. 4 B and Fig. 5, Fig. 5
Block diagram in embodiment.Fig. 5 shows that the board 3 of assembling photographing module 2, board 3 include fixture 31, external camera shooting dress
32 and judgment module 33 are set, the function of fixture 31 is to clamp non-circular eyeglass 20, to adjust the setting position of non-circular eyeglass 20
Angle is set and is arranged, wherein board 3 further includes dynamical element (not shown in the figures), is connected to fixture 31, dynamic to provide
Power gives fixture 31, keeps fixture 31 mobile or rotation.The function of external pick-up device 32 is to shoot non-circular eyeglass 20 and induction
Chip 21, to assist the rwo alignment work, and judgment module 33 is connected to external pick-up device 32 and induction chip 21,
Its function is to judge that non-circular eyeglass 20 and induction chip 21 are complied with standard in whether optics aspect and configuration aspects reach
Configuration.Operation as external pick-up device 32 and judgment module 33 will be described in detail in back segment.
The assemble method of photographing module 2 is to carry out step A first: providing non-circular eyeglass 20 and induction chip 21, such as
Shown in Fig. 2.Next carry out step B1-1 using fixture 31: mobile non-circular eyeglass 20 makes non-circular eyeglass 20 be located at induction
The top of chip 21.After the top that non-circular eyeglass 20 is located at induction chip 21, shot using external pick-up device 32 non-
Circular eyeglass 20 and induction chip 21, and obtain the first edge image for corresponding to the long side edge 202 of non-circular eyeglass 20
And the second edge image of the long side edge 212 corresponding to induction chip 21, that is, carry out step B1-2.Due to judgment module
33 are connected to external pick-up device 32, thus judgment module 33 can get corresponding to non-circular eyeglass 20 first edge image and
Corresponding to the second edge image of induction chip 21, to carry out step B1-3: judge first edge image whether with second edge
Image alignment, that is to say, that judgment module 33 can be judged by step B1-3 non-circular eyeglass 20 long side edge 202 whether
It is aligned with the long side edge 212 of induction chip 21, to meet the standard of configuration aspects.In this preferred embodiment, judge non-circular
It is length according to non-circular eyeglass 20 that whether the long side edge 202 of shape eyeglass 20 is aligned with the long side edge 212 of induction chip 21
Whether side edge 202 in horizontal direction in being aligned with the long side edge 212 of induction chip 21.
When judgment module 33 judges first edge image with second edge image alignment, step B1-4 is carried out: judgement
The long side edge 202 of non-circular eyeglass 20 has been aligned with the long side edge 212 of induction chip 21.And when judgment module 33 judges the
When one edge images and second edge image are unjustified, then step B1-1 is carried out again, that is to say, that can be according to first edge shadow
Picture and the relative position between second edge image, move non-circular eyeglass 20 again, then carry out step after having moved again
B2-2~step B2-3, until judging first edge image with second edge image alignment.
After step B1 completion, step B2-1 is carried out by fixture 31: adjusting the setting angle of non-circular eyeglass 20,
It is arranged after angle adjustment completion, continues step B2-2: external beam being made to be projected to induction by non-circular eyeglass 20
On region 211, to generate the image for corresponding to above-mentioned setting angle.Since judgment module 33 is connected to induction chip 21, therefore sentence
Disconnected module 33 can get the image that angle is arranged corresponding to it, and can carry out step B2-3: judge whether image is qualified.Therefore,
Judgment module 33 can determine whether the setting angle of non-circular eyeglass 20 meets the standard of optics aspect.
In step B2-3, when judgment module 33 judges the image qualification, carries out step B2-4: judging non-circular eyeglass
20 have been aligned with induction chip 21.And judgment module 33 then carries out step B2-1 when judging that the image is unqualified again, that is,
It says, judgment module 33 can determine that it is arranged angle and is according to the image of the setting angle imaging of current non-circular eyeglass 20
It is no appropriate, step B2-1~step B2-3 is repeated if its setting angle is not appropriate, until it is arranged corresponding to angle
Until image is qualified.Step B completes to indicate that the imaging surface of non-circular eyeglass 20 has covered the induction zone of induction chip 21 really
Domain 211.
After step B completion, step C is carried out: encapsulating non-circular eyeglass 20 and induction chip 21 and form camera shooting mould
Block 2, wherein this known those skilled in the art that operate to about the other elements in setting photographing module 2 extensively know, therefore no longer go to live in the household of one's in-laws on getting married
It states.Finally, carrying out step D: setting photographing module 2 is in the narrow space 40 of portable electronic device 4, wherein narrow space
40 width W is less than the catercorner length P of induction region 211, as shown in Figure 6.
Specifically, the maximum length L2 of non-circular eyeglass 20 is the diameter of the circular eyeglass before cutting, rather than
Catercorner length P of the maximum length L2 of circular eyeglass 20 at least equal to induction region 211, therefore the circular eyeglass institute group before cutting
Dress and the size of photographing module generated is naturally larger than the width W of narrow space 40, and can not be incorporated in narrow space 40.
Therefore, by the structure of cropped non-circular eyeglass 20, photographing module 2 of the present invention can be housed inside portable electronic dress really
It sets in 4 narrow space 40, to solve problem of the prior art.
The above description is only a preferred embodiment of the present invention, the claim being not intended to limit the invention, thus it is all its
It is intended to be limited solely by the claim of the disclosure without departing from the equivalent change or modification completed under design disclosed in this invention
It is interior.
