Problems solved by technology

However, due to the small diameter of the CCD lens and the small effective viewing angle, if it is used in handheld appliances such as smart phones (SmartPhone), video phones (Video Phone), digital cameras and handheld computers (Handheld PC), the user faces the CCD The lens must use the camera's "Self-View" function to detect whether it has deviated from the center of the lens, which is quite inconvenient to use
[0003] Therefore, it can be seen from the above that the above-mentioned known CCD lens obviously has inconvenience and defects in actual use, and needs to be improved.

Embodiment Construction

[0010] see figure 1 , figure 2 , the present invention provides a lens with a guiding and aligning device, which uses simple geometric principles to achieve the purpose of guiding and aligning the lens. It is especially suitable for general CCDs, and can also be used for other image sensing lenses such as CMOS lenses, etc. .

[0011] The lens includes a lens inner wall 10 , at least one alignment point outer wall 20 , a lens 30 , at least one light source 40 and an image sensor 50 . The lens inner wall 10 is in the shape of a circular hollow tube, and its front and rear ends form openings.

[0012] The outer wall 20 of the alignment point is in the shape of a circular hollow tube, and is arranged on the outer edge of the inner wall 10 of the lens. The outer wall 20 of the alignment point is hollow inside to form a lens alignment point 21. The outer wall 20 of the alignment point is arranged on the lens alignment point 21 The periphery of the lens is used to fix the light s...

Abstract

A lens with a guiding and aligning device is suitable for general CCD lenses, and can also be used for other image sensing lenses such as CMOS lenses. A lens alignment point is designed on the outer edge of the lens. The bottom of the lens alignment point is a light source. The alignment point generates a "lens alignment angle" according to the depth of the light source embedded and the outer wall of the alignment point. When the user faces the lens, if he sees the light source in the point where the lens is aimed, it means that the effective shooting range of the lens has been aligned. Thereby, the user can be guided to align the lens, which is very convenient for the user.

Description

technical field [0001] The present invention relates to a kind of lens that has guiding alignment device, relate in particular to a kind of lens that is suitable for general CCD (Charge Coupled Device; Electrically Coupled Device) lens, also can be used for other image sensing lens such as CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor) lenses, etc. A lens alignment point is designed on the outer edge of the lens. When the user faces the lens, if he sees the light source in the lens alignment point, it means that the effective shooting range of the lens has been aligned. Background technique [0002] The known CCD image sensor is one of the image sensors that have drawn attention in recent years. The CCD has a photoelectric conversion function, a signal charge accumulation function, and a signal charge transfer function. The CCD image sensor is widely used in the lens of palm-sized electrical appliances because of its small size, ligh...
