Переведите пожалуйста текст и ответьте на вопросы.
A flatbed scanner can capture colour pictures, documents, pages from books and magazines and, with the right attachments, can even scan transparent photographic film. Using cunning software they can read pages of words and convert them into editable text documents, saving you from all that tiresome typing. Photographic images can be scanned and manipulated in all manner of ways, from retouching the scratches and marks of time, to adding a comedy moustache to Uncle Bob's photo for that perfect family Christmas card! Perhaps you'd like to have your logo scanned so you can place it on your business cards and letterheads? And what about getting images onto your web site? Whatever the application, a scanner will end up being one of the most useful and versatile peripherals you've ever bought. And with prices this cheap, there's no need to delay. All scanners work on the same principle of reflection or transmission. The image is placed before the scanning head, which consists of a light source and sensor. The amount of light reflected by (or transmitted through) the image is gathered by the sensor, then converted to a voltage proportional to the intensity of light: the brighter the part of the image, the more light is reflected or transmitted, resulting in a higher voltage. This voltage is finally converted by an analog-to-digital converter into bits of information which the computer can manipulate. The sensor used in desktop scanners is a charge-coupled device, or CCD. The same device is used in video and digital cameras. A CCD consists of many photosensitive elements arranged in a grid in the case of a video or digital camera, or in a long, thin line in the case of desktop scanners. The more photo-sensitive elements per unit length, the higher its resolution.
1) What can a scanner be used for?How does the amount of light influence the voltage? 3) Where are CCD used? 4) The text you get while scanning isn’t it? 5) Why is scanning so convenient? 3 Give the main idea of the whole text in 5-7 sentences
