  • Page 54: Scanner Terms

    Service Guide SD One+ Appendix C Scanner Terms Activation Code: Is the when the product specific License code has been pared with a Scanner serial no. AdaptiveThresholding: Advanced 2-D Adaptive Thresholding estimates the background grey level in a window area around each pixel. The difference between the actual pixel value and the background is then compared to the adaptive settings to determine if a pixel is thresholded as a black or a white pixel.
  • Page 55 Service Guide SD One+ ATAC: Automatic Thickness Adjustment Control - A special technology that allows the scanner pressure platen to be raised to accommodate thick originals and then lowered - both actions performed by pressing a key from the operators panel.
  • Page 56 Service Guide SD One+ CCD: Charge Coupled Device, CCD is the image sensor in the scanner that converts light to voltages. These voltages are converted by the scanner into the image. CCITT Group3: Standard run-length compression format used with FAX transmission. It utilizes modified Huffman coding to further compress the run-length numbers.
  • Page 57 Service Guide SD One+ Color Management System: Color Management System (CMS) software increases the accuracy of color interchange between scanners, displays and printers based on profiles for each device. The CMS is a layer of software resident on the computer that negotiates color reproduction between the application and color devices.
  • Page 58 Service Guide SD One+ Dither: To use patterns of different colored pixels to create blended colors; or, to use dots of different sizes to simulate greyscale images. (see below). Dithering: A printing or display device may have only a small number of greyscale or color values for each device pixel. However, if the viewer is sufficiently distant from the printed page or display, the value of neighbouring pixels can be set so that the viewer’s eye integrates several pixels to achieve an apparent improvement in the number of levels or colors that can be reproduced.
  • Page 59 Service Guide SD One+ Foreground: Foreground when scanning raster data (black and white, or monochrome data) refers to the pixels that represent data of interest (background refers to everything else). Typically, lines and shapes are represented by black pixels (foreground) and empty space is represented by white pixels (background). When scanning greyscale data, background means the grey level of a region of pixels that surrounds some desired foreground data.
  • Page 60 Service Guide SD One+ HSV: A color space with the three variables of Hue, Saturation, Value. Hue means color (as in the color wheel.) Saturation is an indication relating to the richness or vibrancy of the color. Value is a term best related to the intensity of light illuminating the object.
  • Page 61 Service Guide SD One+ Lossy Compression: File compression that will compress data to a high degree. When subsequently un-compressed, data will have been lost. LZW: Method of lossless compression used with many file formats; developed by Lempel, Zev and Welch. Midtones: The most important part of a picture between black (shadows) and white (highlights).
  • Page 62 Service Guide SD One+ Pixels: The word pixel is a combination of the two words picture and element. It is the smallest building block within a scanned line-art or photographic image. A pixel is the small square picture element that is filled with a color, black or white.
  • Page 63 Service Guide SD One+ A method of compressing raster or bitmap data by representing “runs” of white or black dots along a scanned line as Runlength Encoding: the number of dots in each run. Many variations of this scheme exist, with varying compression efficiency. Typically, run length compression formats yield a file 20-25% the size of an uncompressed file.
  • Page 64 Service Guide SD One+ sRGB: Hewlett-Packard and Microsoft proposed the addition of support for a standard color space, sRGB, within the Microsoft operating systems, HP products, the Internet, and all other interested vendors. The aim of this color space is to complement the current color management strategies by enabling a third method of handling color in the operating systems, device drivers and the Internet that utilizes a simple and robust device independent color definition.
  • Page 65 Service Guide SD One+ TWAIN: A standard method of communications that programs can use to send instructions to hardware (such as scanners) and receive data back from them (such as pictures). UCR: Under Color Removal. A color separation setting used on color photographs where cyan, magenta and yellow inks are removed from dark, neutral areas and substituted by black ink.
