Problems solved by technology

However, due to the interference of infrared light on normal mobile phone cameras, there will be infrared filters inside the camera of conventional mobile phones to prevent infrared light from entering the sensor, so as to ensure the effect of normal photo taking
Therefore, conventional mobile phone cameras cannot be used to capture iris images illuminated by infrared light sources
like figure 1 As shown, it is an anatomical diagra

Example Embodiment

[0034] Example 1:

[0035] In order to realize that the mobile phone camera can perform both normal shooting and iris shooting, this embodiment provides a terminal camera module, including: a first filter, a second filter, a switching module and a terminal camera module body the first filter and the second filter are located above the terminal camera module body; the terminal camera module body can receive infrared light and visible light;

[0036] The first filter is used to filter out infrared rays in the rays received by the terminal camera module;

[0037] The second optical filter is used to filter out all visible rays in the rays received by the terminal camera module and only allow infrared rays to pass through;

[0038] The first filter is used to filter out infrared light in the light before the external light enters the terminal camera module body;

[0039] The second filter is used to filter out all visible light in the light and only allow infrared light to pass ...

Example Embodiment

[0061] Embodiment 2:

[0062] This embodiment provides a terminal, including: the terminal camera module described in the first embodiment.

[0063] Specifically, the terminal camera module can be electrically connected to the terminal motherboard through the FPC.

Abstract

The invention discloses a terminal and a terminal camera module. The terminal camera module comprises a first optical filter, a second optical filter, a switching module and a terminal camera module main body; the first optical filter and the second optical filter are positioned above the terminal camera module; the terminal camera module can receive infrared light and visible light; the first optical filter is used for filtering infrared light in the light before external light goes into a terminal camera module main body; the second optical filter is used for filtering visible light in the light and only allowing the infrared light to pass through before the external light goes into the terminal camera module main body; the switching module is used for changing positions of the first optical filter and the second optical filter relative to the terminal camera module main body to realize switching between the first optical filter and the second optical by the terminal camera module to filter the external light. The terminal and terminal camera module can make a mobile phone camera to either perform normal shooting or perform iris shooting.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a terminal and a terminal camera module. Background technique [0002] With the rapid development of information technology, illegal computer login cases, mobile phone privacy, bank card and other fraud cases are on the rise, and various cases of forged documents and falsely claiming legal items are also emerging. Therefore, effective identification of personal identities is of great importance to the society and Economic development is of great significance. [0003] As an important identification feature, the iris has the advantages of lifetime uniqueness, stability, collectability, and non-invasiveness. It is an inevitable trend in the development of identification research and application. Compared with identification methods such as fingerprints and face images, iris has higher accuracy, coupled with the lowest false recognition rate, it has become the first choic...
