The ability to capture still images, or motion pictures, with a device no bigger than the palm of your hand, to edit, and manipulate those images, yourself, and to distribute them, electronically, with no development or printing costs, may seem like a dream come true for users of traditional, analogue recording technology. These features are, nevertheless, a fact of life when it comes to digital cameras and camcorders, so it is easy to see why the new technology has become so popular. Digital Camera Camcorder FeaturesDigital cameras and camcorders use no film, and rely instead on a photosensitive microchip, known as a” Charge Coupled Device” CCD, or” Complementary Metal Oxide Semiconductor” CMOS image sensor, which converts the light falling on it into a series of numeric values a string of” 1″ s and” 0″ s representing each” pixel”, or” picture element”, of an image. A pixel can be visualised as a tiny dot, or square, and hundreds of thousands, or millions, of pixels go together to form a complete image. The term” megapixel” Mp, often bandied about in connection with digital cameras and camcorders, simply means one million pixels. The total number of pixels, or megapixels, determines the” resolution” of an image sensor, or an image recorded with it; the higher the number of pixels, the higher the resolution, and the higher the level of detail in a finished image. The Mustek DV5200 model, for example, features a 2. 0Mp resolution CMOS sensor. Resolution not only determines the quality of a finished image, or series of images, but also the total amount of storage space required; the higher the resolution, the larger the size of the file that a photograph, or video footage, will occupy. Digital cameras generally use memory expansion cards as storage media; you may have come across” SD” ” Secure Digital”, ” CF” ” CompactFlash”, or” Memory Stick” memory cards, and there are several other formats. Many manufacturers” bundle” together a compatible memory card typically with a storage capacity of 32MB with a digital camera, but do bear in mind that this will only hold a limited number of shots, especially at higher resolutions. For even for a 2Mp, or 3Mp, camera, a high capacity 512MB, and upwards memory expansion may be a more practical alternative in the long term. The Mustek DV8200 model, for example, supports SD and MMC memory expansion cards. About MustekMustek, Inc. is a world leader in the development, manufacture and distribution of digital imaging products, notably scanners, but also digital cameras and camcorders. Originally founded in 1988, Mustek has manufacturing facilities in Taiwan and China and satellite offices in Germany, and in the United States. ConclusionThe appeal of digital recording, with a digital camera, or camcorder is not limited just to the superb quality images, video and audio that can be captured, but extends to what can be done with the material after capture. Fast, efficient download via FireWire, USB, or memory card transfer means that pictures can be on your PC almost as soon as they are taken, and can be shared with others in many different ways. A digital photo frame, for example, allows you to upload digital photographs direct from your camera, or PC, and share them with friends or relatives who do not have a computer of any kind.
