How does a Digital Camera Work?

Instead of exposing a photosensitive chemical known as film to a scene to create an imprinted image, most digital cameras use a charge-coupled device (CCD), an electronics instrument that creates a pixel map based on the electric charge generated when photons slam into a sensitive material. This phenomenon is called the photoelectric effect, and was elucidated by Albert Einstein in a famous 1905 paper. Less frequently used than a CCD is a complementary-metal-oxide-semiconductor (CMOS). Because it is the digital camera mechanism in the minority, the CMOS will not be discussed in this article.
