USB Camera Module

Camera Module is generally composed of the following parts: Lens, image sensor, base bar and line.

If it is a camera module with AF function (generally a mobile phone camera), most of them adopt VCM mode, which has one more coil than the above structure. By adding points to the coil, the lens can move vertically to achieve the function of focusing. In the case of a camera with a shake resistant feature, the lens is also able to move horizontally to achieve an optical shake resistant effect


Camera module selection


The sensor and lens in the camera module usually account for more than 90% of the cost, and the image quality is also determined by them.


First, choose the most appropriate sensor according to the price you can accept, the interface of the motherboard, and the resolution you need to take photos and video

The price of the sensor usually accounts for 40%-60% of the price of the module. In order to ensure that the resolution/frame rate can meet the requirements, sensors with better sensitivity and larger pixel area are selected at a certain cost.


Secondly, according to the purpose of the sensor you need, choose the lens with the appropriate size and field of view Angle. If a lens with a large field of view is needed, you can choose a fish-eye camera (also known as a wide-angle camera). However, for the image taken by the fisheye camera, there will be a distortion effect. In fact, the distortion effect can be corrected by itself.
