An optical character recognition machine which consists of a scan head, a computer processor, and an output device Used for interpreting documents, invoices, bar-codes, and photos for use in Color separations
a radar dish that rotates or oscillates in order to scan a broad area an electronic device that generates a digital representation of an image for data input to a computer someone who scans verse to determine the number and prosodic value of the syllables
An optical device that converts images - such as photographs - into digital form so they can be stored and manipulated on computers Different methods of illumination transmit light through red, green and blue filters and digitize the image into a stream of pixels
A device that can read text or illustrations printed on paper and translate the information into a form the computer can use A scanner works by "digitizing" an image and placing it on the computer as a file
(n) A computer input device used to capture information on paper and translate the information into a raster (bitmapped) computer image Scanners can be used to convert a drawing created with traditional tools to a CAD drawing, to convert and enhance photographs in desktop publishing, or to input text information into the computer
A machine that scans a printed image, such as a photograph or a page of text, and turns it into a file that can be displayed and manipulated on a computer
a radio receiver that that moves automatically across some selected range of frequencies looking for for some signal or condition; "they used scanners to monitor police radio channels"
The instrument carried aboard the satellite which views the earth Examples are AVHRR, CZCS, SeaWiFS and MODIS Typically the scanner is simultaneously sensitive to a number of parts (bands) of the visible and infra-red spectrum It will rotate, scanning the earth directly underneath the satellite (the sub-satellite point) from left to right The data will then be transmitted to earth as one scan-line, typically 1000 to 2000 points across, each point having values for the parts of the spectrum seen By the time the scanner comes back to the start the satellite will have progressed so a different part of the earth is seen See also Sensor
An image input device that interprets the reflected light from a physical image and translates it into a stream of pixels, digitized raster data or a stream of bits
An input device for a computer that digitizes a photograph or other optical image into a binary representation A scanner may be linked to optical character recognition software allowing printed documents to be converted directly to machine-readable text files
An electronic input device that converts art or continuous - tone images into digital form Digital scanners convert line art (black-and-white), monochrome images (gray levels), and full-color images into pixel arrays Some scanners are also color separation machines that use circuits to color-correct, compress the tone, and enhance detail
(1) Any device that scans, and thus produces an image (2) A radar set incorporating a rotatable antenna for directing a searching radar beam through space and imparting target information to an indicator
An input device that uses light to read printed information including text, graphics, and bar codes, and transfers it into the computer in a digital format
A scanner is a machine which is used to examine, identify, or record things, for example by using a beam of light, sound, or X-rays. brain scanners. a security scanner that can see through clothes
n An optical input device that uses lightsensing equipment to capture an image on paper or some other subject The image is translated into a digital signal that can then be manipulated by optical character recognition (OCR) software or graphics software Scanners come in a number of types, including flatbed (scan head passes over a stationary subject), feed (subject is pulled across a stationary scan head), drum (subject is rotated around a stationary scan head), and handheld (user passes device over a stationary subject)
A device used to turn hardcopy output such as paper, slides, or transparencies into digital information for the purpose of manipulating and reproducing on the computer
A peripheral device enabling the input of external images and text to a computer; a scanner records images from a printed page, photographic film, or other source and converts them into a digital form that a computer can manipulate and display
A hardware device used to "read" text or pictures into an associated computer programme, where the material can then be electronically manipulated Hand-held and flat-bed scanners (i e desktop) are two types of scanner that are commonly available
a device you can connect to your computer that will scan or "copy" pictures or objects so that you can store that image as a file on your computer; there are flat-bed scanners that look somewhat like a copy machine and there are hand held scanners
A device for capturing a digital image There are many types of scanners, such as flatbed scanners, drum scanners, slide scanners, and microfilm scanners
