How do digital video cameras work?

A digital camera takes light and focuses it via the lens onto a sensor made out of silicon. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of “picture element”. There are millions of these individual pixels in the sensor of a DSLR camera.

Cameras use convex lens to take real inverted images. This is because light rays always travels in a straight line, until a light ray hits a medium. The medium in this case is glass. The glass causes the light rays to refract (or bend) this causes them to form inverted on the opposite side of the medium.

What is analog camera?
