December 13th, nuclear proof i« hundred six, invention description: [Technical field of invention] [0001] The present invention relates to a lens, in particular to a lens for a digital camera. [Prior Art 3 [ 0002] With the development of multimedia technology, digital cameras and video cameras are increasingly favored by consumers. When people pursue digital cameras and cameras, they put forward higher requirements on the image quality of the objects they shoot. It is hoped that the image of the object is clear, and the image quality of the object depends to a large extent on the quality of the optical instruments in the digital camera. [0003] Compared to other general optical instruments in digital cameras, digital camera lenses are relatively complex in structure and generally consist of several lenses. When these lenses are optically designed, their relative positions are designed to be completely ideal. The lens of the digital camera is usually placed in the lens barrel, so 'a good lens needs to have a good and reasonable frame and lens barrel design, and the design should be a good assembly method for the lens barrel to make the object from the object. The light is accurately focused through the lens and prevents stray light from entering the digital camera to ensure a good image quality for the digital camera. [0004] In general, a digital camera lens limits the angle of incident light entering the digital camera to 'prevent the influence of other stray light on the image sensing element'. The lens barrel is usually formed into a beveled shape to block other stray light from entering the digital camera. In the actual process, it is impossible to project a lens barrel with a completely pointed bevel by plastic injection. Therefore, in practice, some unnecessary incident light is limited. Referring to the first figure, the digital camera module includes a lens barrel 12, a lens 14, and an image sensing module 16. Lens barrel 12-end opening 'other 094131033 Form No. A〇lQl g 12 ¥ 丨__卜0 1363883 [0005] [0007] [0008] One end is semi-closed, and the half-closed end of the barrel 丨2 opens a "" The Y-shaped opening 122 has a tapered wall 124 and a dome-shaped wall 125 corresponding to the "Υ"-shaped opening 122 on the lens barrel 12, thereby forming a platform 126 on the lens barrel 12. The lens 14 includes a lens portion 142 and a mounting portion 144, and the surface of the mounting portion 144 is flat. When the image of the object is captured by the digital camera module, a portion of the external light ray is incident on the mounting portion 144 of the lens 14 adjacent to the platform 126 and enters the digital camera module, that is, the portion of the light A is not lensed by the lens μ. The portion 142 focuses directly into the digital camera module to form stray light, thereby causing interference to the image sensing module 16, affecting the image sensing quality of the image sensing module 16, and reducing the imaging quality of the digital camera module. ® In view of the above shortcomings, it is necessary to provide a lens that prevents the effects of stray light, improves the image quality of the digital camera module, and a digital camera module with high image quality. SUMMARY OF THE INVENTION The above content provides a lens that prevents the influence of stray light and improves the imaging quality of the digital camera module. In addition, a digital phase detector module for preventing stray light images and high image quality is provided. The lens 'includes a lens portion located at the center of the lens and the mounting portion of the lens surrounding the lens β. The surface of the lens portion surrounds the lens portion to expose the lens to the mounting portion of the lens. The light is deflected away from the light material of the lens. A digital camera module includes a unit. The lens is located in the lens barrel, the lens barrel, a lens and an image sensing lens include a lens center 094131033 Form No. 1010101 Page 4 / Total 12 Page 1003460451-0 1363883 Nuclear 100 years 1Z 13th lens section And a mounting portion surrounding the lens portion, a surface of the mounting portion is disposed around the lens portion, and the deflecting structure causes the light incident on the mounting portion of the lens to move away from the optical axis of the lens The deflection structure of the deflection. The image sensing unit is configured to receive an optical signal from the lens. [0010] Compared with the prior art, the digital camera module provides an annular wall deflection structure through the digital camera module to prevent deviation from the lens. The incident light of the lens portion enters the image sensing unit of the digital camera module, thereby improving the imaging quality of the digital camera module. [Embodiment] Referring to the second figure, a digital camera module 20' disclosed in the preferred embodiment of the present invention includes a lens barrel 22, a lens 24 and an image sensing module 26. The lens 24 is received in the lens barrel 22, and the image sensing module 26 is located at the rear end of the lens barrel 22 for receiving the light signal from the lens 24. [0012] The lens barrel 22 is a hollow cylinder including a top portion 221 and an open end 222 opposite the top portion 221 . The center of the top surface 221 defines a "Y" shaped opening 223' corresponding to the "Y" shaped opening 223 of the lens barrel 22 having a tapered wall 224 and a cylindrical wall 225. [0013] 094131033 Please also refer to the third figure, the lens 24 is used to focus the incident light from the object, which is a circular lens whose outer diameter is matched with the inner diameter of the lens barrel 22, and the outer circumferential surface 241 is matched with the lens barrel. A circumferential surface 228 within 22. The lens 24 includes a lens portion 242 at the center of the lens 24 and a mounting portion 243 surrounding the lens portion 242. The mounting portion 243 has an upper surface 244 and a lower surface 245. The upper surface 244 of the mounting portion 243 abuts the lens portion. A groove 246 is formed in the 242 ring, and an annular wall 247 corresponding to the groove 246 is formed on the wearing portion 243, and the ring form number AG1G1 is 5th/12 pages 丨003460451-0 1363883. The bead wall 247 has a bottom end 248 adjoining the bottom of the groove 246 and a top end 249 connected to the upper surface 244 of the mounting portion 243. The diameter of the annular wall 247 is gradually increased from the bottom end 248 toward the top end 249 and the top end 249 The diameter is the same as the diameter of the cylindrical wall 225 of the top 221 of the lens barrel 22. The annular wall 247 can be a planar wall or a curved wall. In the embodiment, the annular wall 247 is a planar wall. [0014] The image sensing module 26 includes a substrate 261 and an image sensing unit 262. The substrate 261 is made of a material such as plastic, fiberglass, reinforced plastic or ceramic. The image sensing unit 262 is received in the lens barrel 22 and is fixed on the upper surface of the substrate 261 for converting the optical image signal from the lens 24 into an electronic image signal. [0015] When assembled, the lens 24 is placed in the lens barrel 22 by the open end 222 of the lens barrel 22, and the outer circumferential surface 241 fits into and fits the inner circumferential surface 228 of the lens barrel 22, and then the lens barrel 22 is placed on the image. The image sensing unit 262 is received in the lens barrel 22 on the sensing module 26, and the lens barrel 22 is fixed on the substrate 261. [0016] When the digital camera module 20 is used, a portion of the incident light rays that are offset from the lens portion 242 of the lens 24, as incident light A1 is incident on the lens 24 as shown in the second figure, due to the annular wall 247 on the lens 24. The refraction of the incident light ray A1 is deflected away from the optical axis of the lens 24 by the exiting ray A2 of the lens 24, and the stray light is prevented from entering the image sensing unit 262 of the image sensing module 26, thereby Part of the stray incident light is shielded to improve the imaging quality of the digital camera module 20. [0017] It can be seen that the digital camera module 20 is configured to prevent the lens portion 242 094131033 from being offset from the lens 24 by providing a deflecting structure of the annular wall 247 on the lens 24.

[0019] 245 only needs to be able to cause the optical signal incident on the mounting portion 243 of the lens to be deflected away from the optical axis of the lens. In addition, the lens barrel 22 of the digital camera module 20 may have a plurality of lenses 24.
