Although the film quality is still higher than the photo provided by digital camera, digital in a certain period of time can not completely replace the traditional camera, but with digital image technology, digital camera is gradually beyond the traditional camera, became more popular. In this article, we will work together to understand the specific working principle of this kind of magic digital device. Digital camera principle Instead of film, digital cameras use sensors to convert light into electricity. The image sensors used by most digital cameras are charge coupled devices (CCD). Some digital cameras use complementary metal oxide semiconductor (CMOS) technology. Both CCD and CMOS image sensors can convert light into electrons. CCD/CMOS sensor is one of the most important components of digital camera, and also the characteristic of digital camera which is fundamentally different from traditional camera. The full name of CCD is Charge Couple DevICe, which translates as light charge coupled device. The full name of CMOS is Complementary, Metal-Oxide, SEMIconductor, and has the meaning of complementary metal oxide semiconductor. The work principle of CCD and CMOS has one thing in common, that is, the light diode is used as the conversion component of the light electric signal. After converting the light into electrons, the sensor reads the value of each battery (accumulated charge) in the
