Under the background trend, the market has higher and higher requirements on the photographing quality of the mobile phone camera, and manufacturers begin to make sufficient efforts on how to improve the imaging quality. The flare phenomenon (the flare and ghost phenomenon is commonly called) existing in the optical system of the mobile phone camera is one of key points influencing the imaging quality, the existence of the flare phenomenon can enable an imaging image surface to generate a bright background, reduce the image surface contrast and reduce a modulation transfer function, reduce the level of the whole image surface, greatly reduce the contrast and the definition, and form flare spots with different sizes in serious cases to disable a mobile phone lens. To improve the above phenomena, we begin with the phenomenon of flare caused by the transmitted light and the reflected light in the non-effective region, which is one of the sources.

In order to achieve the purpose, the invention adopts the technical scheme that:
a film coating method for blackening the non-effective diameter of a resin lens in a mobile phone camera uses an electron beam vacuum evaporation film coating machine to perform the following operations:
1) Sanding and roughening the non-effective diameter of the target lens;
2) A coating jig is adopted to shield the effective diameter of the target resin lens, and the non-effective diameter is exposed;
3) Selecting a high-absorption metal oxide material to carry out single material coating, wherein the thickness of a film layer is more than five optical wavelengths;
4) No ion source assisted deposition or ion source assisted deposition is used.
The invention has the beneficial effects that:
1. the flare phenomenon formed by the transmission of the non-effective diameter area of the resin lens in the camera of the mobile phone and the reflected light is improved.
2. the imaging quality of the mobile phone camera is improved, the lens competitiveness is improved, and the method is suitable for batch processing production.

Detailed Description
The invention is described in further detail below with reference to the accompanying figures 1-3 of the specification.
a film coating method for blackening the non-effective diameter of a resin lens in a mobile phone camera uses an electron beam vacuum evaporation film coating machine to perform the following operations:
1) Sanding and roughening the non-effective diameter of the target lens;
2) a coating jig is adopted to shield the effective diameter of the target resin lens, and the non-effective diameter is exposed;
3) selecting a high-absorption metal oxide material to carry out single material coating, wherein the thickness of a film layer is more than five optical wavelengths;
4) no ion source assisted deposition or ion source assisted deposition is used.
In the step 4), if the film adhesion is increased, an ion source is used for assisting deposition, and oxygen cannot be filled.
The test according to the method above determines the result:
as shown in FIG. 1, the average reflectivity of the corresponding wavelength of 380nm-740nm is only 0.85%, and the light reflection on the surface of the non-effective-diameter area is effectively reduced;
as shown in fig. 2, the average transmittance corresponding to the wavelength of 380nm to 740nm is only 5.13%, which effectively reduces the light transmittance through the non-effective-diameter region;
as shown in FIG. 3, the average absorption of the corresponding wavelength of 380nm-740nm is as high as 94.02%, and the light passing through the non-effective diameter area is effectively absorbed, so that the light is blocked. The color of the non-effective area was visually observed as black or dark brown.
