Please teach me about camera circuits [Copy link]

Is there any hardware expert who is good at camera, can you tell me the knowledge about camera circuit, such as what are the interface signal lines, etc.

High-end cameras generally use MIPI-CSI. Although I haven’t learned much about it, I have used MIPI-DSI, and the communication method should be similar.

There are so many types of cameras, analog, digital, and with different interfaces. If you are engaged in related work, you should start by learning about the products of your company.

There are two main types of surveillance cameras in the industry: analog cameras and digital or network cameras.

The main camera module interfaces are: USB, DVP, MIPI (CSI) , etc.

DVP devices are relatively old and below 500W. They are commonly found in medical equipment, but they are basically being eliminated in recent years. USB cameras generally do not have very high resolutions and are commonly found in some devices such as laptops. MIPI devices are relatively complex and have many interface standards, but they have become more popular in recent years. Some MCUs also have this interface. This interface has differential output and is good in both transmission and anti-interference. It is similar to the HDMI in the video. There are also some high-end interfaces, mainly in professional equipment such as Sony and Nikon, mainly to monopolize the high-end market and protect technology, so the standards are not open.

The camera depends on whether it is digital or analog.

Thank you for the detailed explanation on the 5th floor!

If you want to know about interfaces, they are basically industry standards. If you want to know about lenses, I know a little bit about them.

Because I have never done any video related projects before, and now I am playing with FPGA, which involves video, so I want to learn it first.
