Lens: indicates the lens. The lens in the lens is divided into spherical surface and aspherical surface. The aspherical surface design is generally used for mobile phone lenses, which can eliminate certain spherical aberration and improve the image resolution.
VCM: stands for voice coil motor, it works on the principle that when the coil is energized, it will generate a magnetic field, and the current flowing through the magnetic field can push the lens forward or backward. This creates a simple motor, a process that converts electrical energy into mechanical energy.
Filter: Filters light invisible to the human eye so that the Sensor only receives light visible to the human eye.
Image sensors, generally divided into two categories, CCD(charge coupled device) and CMOS (complementary metal oxide)
