First, the main structure and components of the camera
From the working principle of the camera, you can list the main structure and components of the camera:
1. Lens (LENS)
The lens structure consists of several lenses, plastic or glass.
2, image sensor (SENSOR)
Can be divided into two categories:
CCD (charge couple device): CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor 3, digital signal processing chip (DSP)
There are many DSP manufacturers, and the more popular ones in the market are: VIMICRO (China Star Micro) 301P/L, SONIX (Matsuno) 102/120/128, ST (Logitech Logitech's DSP provider), and SUNPLUS (SUN+ focus on single-chip development CIF and VGA, but the image quality is normal), PIXART (original phase) PAC207 single-chip CIF, SQ (reliable) SQ930C and so on.
4, power camera requires two internal working voltage: 3.3V and 2.5V, the latest technology chip useful to 1.8V.
Second, the camera works
The optical image generated by the lens (LENS) is projected onto the surface of the image sensor, and then converted to an electrical signal, converted to a digital image signal after A/D (Analog to Digital conversion), and then sent to a digital signal processing chip (DSP) Processing, and then through the USB interface to the computer for processing, through the monitor you can see the image.
