Digital Imaging Explained

By Warren Lynch

Digital Imaging is a process where an electronic photograph, scanned document, or image is converted into a series of electronic dots called pixels. Pixels is an acronym for "picture elements".

Afterrepparttar image is converted, or digitized, it is stored on a memory storage device which may be a hard drive or some sort of electronic storage device such as a memory stick. The pixels are stored in a compressed format to save storage space.

As each pixel is being created it is assigned a color value, called a tonal value, of black, white, shades of grey, or an actual color. These pixels must be processed by a piece of software in order for them to be called up and viewed as an actual image later.

Traditional cameras capture images onto film while digital cameras use an electronic chip known as a Charged Coupling Device (CCD). The CCD is actually a grid of miniature light-sensitive diodes. These diodes convert photons (light) that strikes them into electrons (electrical impulses). The technical name for these diodes is 'photosite'.

After convertingrepparttar 116107 photons into electrons, a mini-computer, located inside ofrepparttar 116108 camera, readsrepparttar 116109 stored electrical value in each photograph. Then a built-in analog-to-digital converter turnsrepparttar 116110 stored electrical value into a digital value. These digital values are then stored onrepparttar 116111 cameras memory storage device. When these digital values are recalled by software, and displayed on a screen, they reproducerepparttar 116112 image that was originally captured byrepparttar 116113 camera or digital input device.
