Scanning tips, Computer Engineering

Assignment Help:

 

  • Don't scan at more resolution than needed. This saves both Disk and time Space.
  • Typically itisn't useful to scan at more than optical resolution because it adds no new information. Interpolation can be done later with Image processing softwares.
  • If scanning photographs for Printers, it is sufficient to scan at one-third the resolution of printing as Printers generally use Super-Pixels (Dithering) for printing. Only for other kind of Printers such as continuous tone Printers, do you need to scan at Printer resolution for best quality.
  • For images to be seen only at the Computer Monitor you may require to only scan so that the image size in pixels is same as the display resolution. I.e. Scan resolution = Height of image in pixels divided by screen size in inches. This may be remarkably small.
