Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
Using a flatbed scanner to scan items other than paper documents exceeds the original purpose of the scanner, so special care must be taken with the process. The bed of the scanner is typically made of glass, and care needs to be taken that the glass not be scratched or cracked when placing or removing items on the bed. Since the items to be ...
CIS of a flatbed scanner. Contact image sensors (CIS) are image sensors used in flatbed scanners almost in direct contact with the object to be scanned. Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor.
The modular design allows the scanner to be accessed both directly or with built-in routines to handle most situations automatically. A message-based interface with tags is used so that features, operations, and formats not yet supported by ISIS can be added as desired without waiting for a new version of the specification.

Scan conversion or scan converting rate is a video processing technique for changing the vertical / horizontal scan frequency of video signal for different purposes and applications. The device which performs this conversion is called a scan converter .
Scan lines are important in representations of image data, because many image file formats have special rules for data at the end of a scan line. For example, there may be a rule that each scan line starts on a particular boundary (such as a byte or word; see for example BMP file format). This means that even otherwise compatible raster data ...
The first step in scanlation is to obtain the "raws" or the original content in print form, then to scan and send the images to the translator and the cleaner. The translator reads original text from the raws and translates into the desired language of release, then sends the translated text to a proof-reader to check for accuracy.
