What is the principle of camera imaging?

Principle: Convert optical image signals into electrical signals for storage or transmission.

When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device, and a "video signal" is obtained.

The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display.

Camera use method

1, protect the LCD screen, and the LCD screen of a digital camera may stick with some fingerprints or dirt that is not easy to erase during use. Besides wiping with a soft cloth, you can also stick a transparent protective film to prevent the screen from being scratched more effectively.

2. Photographers should pay attention to the connection between the cable and the video recorder when grabbing the lens, never run away with the machine, and ignore that the cable is still connected to the video recorder to prevent the cable from breaking the connection in the video recorder or camera cable due to excessive force.

The camera should be protected from the rain. Avoid using the camera in damp, high temperature, places where sharp objects scratch the lens, there is much dust and strong magnetic field. These factors will cause great damage to the camera or cause machine failure.

4. Because most cameras use camera tubes, long-term exposure to light or strong reflection may burn out the camera tubes. When the camera is in use, it can't face the light and the sun, let alone focus on them. This kind of loss should be avoided.
