How a digital camera captures an image?

A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.

What do digital cameras record the image on?

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.

What part of the camera captures light and converts it into a digital image?

When a picture is taken, the CCD is struck by light coming through the camera’s lens. Each of the millions of tiny pixels that make up the CCD convert this light into electrons. The number of electrons, usually described as the pixel’s accumulated charge, is measured, then converted to a digital value.
