Description of the invention: [Technical field of the invention] The present invention relates to a method for observing the lens of the aging lens, in particular, the lens alignment of the vertical alignment of the lens optical axis and the image sensor.碉[Prior Art] ° With the continuous development of digital technology, camera digital cameras have been used by people in recent years, such as mobile phones and PDA (personal digital assistants) and other portable electronic devices. With the development of multi-functionality, digital camera modules and these portable electronic companies have become the key to the development of mobile multimedia technology, and the portable electronic step \, , · °σ has a small and simple structure, its lens The manufacture and __财容=, with the influence of error, the image sensor of the camera module and the optical axis of the lens are not ^=, that is, the mirror has the navigation of Dinglin. The narrative causes the shadow to appear directly. The image is not sharp, causing the image to be brighter and clearer. (4) ―: 丨 is more blurred, ^, it sounds the quality of the image. For example, the Chinese bulletin number is on the 2nd side of the 46th '^ and the shadow group, which uses the elastic elements and screws between the base and the circuit board to adjust the structure. The sensor module of the camera module is arranged, and the adjustment is limited to the manufacturing precision of the component, which affects the adjustment precision, for example, the setting === structural degree, thereby increasing manufacturing difficulty and cost.胄 状 ( (4) 杂 有 有 于此 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' It is really necessary. [Summary of the Invention] The machine can be used to implement the invention. In order to achieve the object of the present invention, the verticality of the optical axis of the lens is measured. The present invention provides a camera module adjustment method, which includes the following steps: providing a test with a Fresnel zone wave pattern test 丨 4Α4Ϊ hole π well, a test chart of Wang Yugong Zhengzheng 锒 ;; use to adjust The photoshooting of the image sensor and the optical axis of the lens group 2 is taken to make the image sensed. The device is perpendicular to the optical axis. The vertical image frequency is read by Lin, and the fine-faced Wei sensor and the optical adjustment method are better than the conventional digital camera lens module adjustment method. The method adopts lens light [embodiment] S or grid tilt - The angle can be formed after the weight is 4, and the method for adjusting the lens verticality of the camera module of the present invention includes the following steps: Please refer to the first figure to provide a camera module to be adjusted. 2〇2, sensor 2〇3, and substrate 耽 The group 2〇 includes 201 203 2; on the sensor 203, the sensor 203 converts the optical signal into fw ΛΚ, , , and . The sensor 203 is surrounded by a plurality of photosensitive pixels to complete an image operation, and the sensor can be c〇) or CM()S. "Formation of Photosensitive Array" The second figure provides a test system 1 which includes 12 and - test boards 13. The test chart u has several Fencer θ1 control devices (zone plate). The graph of the test chart is as shown in the second figure, and the pattern of the F-Ie interval is equal to the area of the center circle. Therefore, the lower the feature is: the size of the pin is small. The test board 13 is provided with relevant circuits and The transmission line 14 can sense the difference between the image signal of the screen of FIG. 11 and transmit it to the monitoring device to test the system to have the _ red computer, the frequency connection, the 叠 = = Similarly, by means of the several pheno-wave ring patterns, the sensor 203 is detected by the lens perception 200904147; the skin, the crystal &&> gtn is suitable for the pattern, and the sensor 2 is judged by the monitoring device 12 3 The optimal verticality is achieved with the nine-axis π of the lens 201. The image module 2Q is recorded on the Lai anti-13, and the second picture on the test board 13 / ι, Γ工广置 12 electrical connection ' Adjust the position of the test chart 11 and the test board 13 so that the second and second plates 13 are directly in front of each other and the heights of the two are equal to the distance, so that the image size produced after the test of FIG. 11, ^, ι, and - is suitable for viewing the 'lens mode 1 and 20 pairs of test Figure 11, 22, take a good angle to the lens. Because of the Philippine ear band wave _ by the lens 201 Measure 3, small real image, and the smaller the distance between the outer ring and the ring, the smaller the distance between the outer ring and the ring, the distance between the ring and the ring is the distance between the ring and the ring on the sensor 2Q3 = =§时' can be superimposed with the sensor 2Q3 to produce the moiré phenomenon shown in the fourth figure, the t-picture = small and complicated 'only when the ants are clear enough to observe the moiré phenomenon, thus The degree of regional crease _ the degree of judging the sharpness of the image, and the other party's _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Around, if you can clearly observe the _ embossing phenomenon, and the i-domain pattern of the i-domain is enough to determine the perpendicularity of the optical axis of the lens and ❹m, so that the better mechanism assembly position of the pedestal 202 can be confirmed. In the monitoring device 12, the image formed by the lens 201 adjusts the relative position of the lens holder 2〇2 and the substrate 2〇4 until the monitoring device detects the phenomenon of the pattern on each of the regions, and the lens holder 2Q2 and the substrate The relative position of Asahi and the process of curing and curing, as shown in the test program in the fifth figure The optical axis of the lens is perpendicular to the sensor. ~ = The density of the spectacles in the method can be changed according to the difference of the lens. The most important condition is to ensure that the band is on the sensor. The imaging of the outer side of the ring is equal to the size of the pixel on the sensor, which can produce a pattern that is easy to analyze, for example. If the sensor has a high ride, then the outer side of the ring The distance between the ring and the ring should be small. It can be understood that the pattern on the test chart u can also be radlatlng lines.
