DIGITAL CAMERA

For more than 200 years, cameras recorded pictures as chemical changes in silver-containing substances, on a strip of flexible, celluloid film. The digital camera records pictures in electronic form. At its heart is a specialized integrated circuit know as a charge-couple device. This has millions of micro units known as pixels. It works in the opposite way to a miniature computer or a TV screen. Instead of the electric signals making pixels shine, when light hits a pixel it generates a tiny electrical signal, according to the lights colour and the brightness. The signals from the CCD’S millions of pixels are analogue: they vary continuously in the wave-like fashion. They are converted by a micro chip to digital codes of the number, represented on the on-off electronic pulses. The digital signal are processed and fed to the cameras internal memory or a removable memory device such as data card and a memory stick. Photographs can be easily downloaded from a digital camera to a computer via a cable or in some cases a wireless link. Some digital cameras automatically reduce blurring caused by camera shake or fast movement, some can records video clips as well as still pictures.
