Sensitive component
As a new type of mobile phone shooting function, the built-in digital camera function is the same as the low-end (100,000 to 1.3 million pixel) digital cameras we usually see. Compared with traditional cameras, traditional cameras use "film" as the carrier for recording information, and the "film" of digital cameras is its imaging and photosensitive device, and it is integrated with the camera and is the heart of the digital camera. The photoreceptor is the core and the most critical technology of a digital camera. There are two core imaging components of digital cameras: one is the widely used CCD (charge coupled) device; the other is the CMOS (complementary metal oxide conductor) device. Since the camera function in mobile phones is emerging, the photosensitive elements used in digital cameras in mobile phones are basically CMOS.
Lens
The lens is an important part of the digital camera, which is divided into CCD and CMOS according to the different components. CCD (Charge Coupled Device) is a high-end technology component used in photography, while CMOS (Complementary Metal-Oxide Semiconductor) is used in products with lower image quality. Its advantages are The manufacturing cost is lower than that of the CCD, and the power consumption is much lower. This is the reason why many products using the USB interface in the market do not require an external power supply and are cheap. Although there is a big difference in technology, the performance gap between CCD and CMOS is not very large. It is just that CMOS cameras have higher requirements for the light source, but this problem has been basically solved. The size of the CCD element is mostly 1/3 inch or 1/4 inch. Under the same resolution, it is better to choose a larger element size.
