What is the imaging principle of mobile phone camera?

CPU integrates video processing system and camera driver. There are 8- 10 data signals between the CPU and the camera, depending on the CPU model and the camera itself. When the mobile phone system enters the photographing or shooting state, the power supply provides a voltage of 2.8V, and the reset signal sent by the CPU resets the camera and starts to transmit data, so that the camera enters the working state.

Influencing factors:

The camera effect of mobile phone is one of the important performance indexes of modern mobile phone, and it is also the core competitiveness of mobile phone enterprises at the technical level. The camera performance of mobile phones will be affected by many factors, specifically, mainly in the following important aspects:

The first is the aperture. Generally speaking, the aperture of a mobile phone camera is similar to the lens of a camera, and its aperture value is inversely proportional to the aperture. However, due to the limitation of structure and volume, the aperture of the lens in modern mobile phones is generally fixed. So the size of its aperture will directly affect the effect of the camera.

Content introduction:

Generally speaking, mobile phone cameras mainly include built-in cameras and external cameras. The built-in camera refers to the camera installed inside the mobile phone, which is more convenient to use. An external camera refers to connecting a mobile phone with a digital camera through a data cable or other means to achieve shooting, which is more convenient to operate.

At present, the digital camera function of mobile phone is still in the development stage, and many technology research and development have just started. The digital camera functions of mobile phones mainly include continuous shooting, built-in flash and automatic white balance, and the shooting effect is closely related to the resolution of mobile phone screen and camera.
