Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0050] see figure 1 , a method for testing the performance of a camera module provided by an embodiment of the present invention. The method includes the following steps:

[0051] Step S1: Provide a camera module.

[0052] Step S2: Check whether the interfaces and leads on the camera module are reliable. That is, check the abnormality of the interface, lead wire, and the welding of each electronic device on the camera module, to avoid the bad situation of the camera module when it leaves the factory, to prevent the misjudgment of the results during the test, and to ensure the accuracy and reliability of the test. This step can be checked visually in brightly lit environments. In addition, the size of the camera module can also be measured by a vernier caliper, so ...

Abstract

A camera shooting module performance test method comprises the following steps of providing a camera shooting module and measuring size parameters of the camera shooting module; electrically connecting the camera shooting module and a DC stabilized power supply and measuring electric parameters of the camera shooting module under room temperature; placing the camera shooting module into a temperature box and testing temperature of the camera shooting module; taking the camera shooting module out of the temperature box and recovering to the room temperature; providing a lamp, assembling the camera shooting module and the lamp, and starting the camera shooting module for discharge testing; carrying out electromagnetic interference tests on the assembled lamp assembly; performing button fatigue tests on the assembled lamp assembly; performing temperature tests on heating devices on the camera shooting module; and placing the camera shooting module into the temperature box, starting a video recording function, and carrying out endurance tests on the camera shooting module. With adoption of the camera shooting module performance test method provided by the present invention, defects of the camera shooting module can be timely found out, and the aims of detecting abnormities caused by designs, manufacturing techniques or assembling and using environments of the camera shooting module are achieved.

Description

technical field [0001] The invention relates to a method for testing the performance of a camera module. Background technique [0002] Camera flashlight not only has the function of mobile lighting, but also has video function, camera function and recording function. When using, various functions are independent of each other and the operation is simple, so it is widely used in security, patrol, duty and miners and other industries. [0003] The shell of the existing camera flashlight is generally made of environmentally friendly alloy material, which is not only wear-resistant and durable, but also waterproof, shock-proof and corrosion-resistant, so it can be used in high and low temperature and other harsh environments. When in use, the camera module inside the camera flashlight will affect the performance of use due to its own production materials, the quality of assembly components and the environment of use, resulting in local abnormalities or failures, thus bringing ex...
