What is a color scanner?
Color scanner is a device capable of capturing images in color and converting them to digital images that can be read by computer for display and storage. Although there are only black and white scanners, almost every scanner available on the retail market is a color scanner. There are many different types of color scanners, including platform, pocket, fed and drum scanners. The drum scanners are most often used in the publishing industry to capture extremely detailed images. The most commonly used type of color scanner for home and office use is a flat surface scanner.
The color scanner is designed to digitize and transfer color images to the computer. Many people scan pictures of black and white or gray scales such as documents on their computer and do not use the colorful ability of the scanner. However, the color scanner is essential if you want to store images taken with nothing but a digital camera on your computer.
Some terminologies associated with coloredScanners include resolution and bit depth . The resolution is measured in dots on the thumb (DPI) and most flat scanners have a resolution of at least 300 x 300 dpi and often higher. The sharpness of the image mostly depends on the brightness of the light source and the quality of the optics in the lens. Bit depth or color depth refers to the number of colors that the color scanner can reproduce. Each pixel in the picture requires at least 24 bits to achieve a "real color" and most standard color scanners provide at least that.
When buying a color scanner, display software should be included. The display software acts as a communicator between the computer and the scanned image. With the display software, the scanned image can be edited in appearance, including color, brightness, sharpness and display size, but the text cannot be edited or changed without buttocks for optical character recognition (OCR). Among the most popular display software packages include OCR software to edit TEcstion scanned from the document.
scanners to suit every need, whether personal or business, can be found in a number of prices and proposals. A very basic color scanner can be purchased from a computer or office dealer for only $ 100 (USD) and more sophisticated, high -quality scanners can be awarded up to $ 1000
