    SCANNER FEATURES A. SCANNER FEATURES SCANNER FUNCTIONALITY This appendix contains descriptions and illustrations of the functions and features provided by your scanner, as well as illustrations of how your scanned images will output based on various specifications. Note: The scanner is controlled by the driver software you are using. Some software does not support all of the functions discussed in this appendix.
  • Page 60 SCANNER FEATURES Function Scanning a selected area of an image using the settings you specify. Usage Enter the settings you want to use, for example, the scan area, scanning composition, resolution, and so forth. Use Scan to scan the image using these parameters. Determine the value of the settings based on the original and the output device (screen, printer, and so forth).

  • Page 61: Scanning Composition

    SCANNER FEATURES Scanning composition Function You can scan using one of three compositions: binary, halftone, or multi-value. Binary scanning records only black and white from the original. Halftone scanning records gray shades from the original using a pattern of black and white dots. Multi-value scanning records grays over 16, 64, or 256 levels.

  • Page 62: Binary Scanning-Threshold

    SCANNER FEATURES Binary Scanning - Threshold Function Binary scanning converts every pixel included in the image to either black or white. When the image contains a gray area, the threshold value determines whether the scanner records the area as black or white.

  • Page 63: Dynamic Threshold

    SCANNER FEATURES Dynamic threshold The scanned image is converted to binary using an appropriate threshold. The threshold is determined by the scanner using an optional image processing unit. Dynamic threshold Note:Dynamic threshold is available only when the optional Image Processing Unit is installed.

  • Page 64: Halftone Scanning

    SCANNER FEATURES Halftone scanning Function Creates the illusion of gray scales by simulating shades of gray from patterns of black and white dots. Usage Use halftone scanning when you are scanning an image that has gray shadings (for example, a photograph) when you want to print or display the image on a monochrome device, such as a laser printer.

  • Page 65: Multi-Value Scanning

    SCANNER FEATURES Multi-value scanning Function Multi-value scanning can record 4, 6, or 8 bits of information for each dot on the image. The 4-bit multi-value data represents 16 different shades of gray, the 6-bit data represents 64 shades of gray, and the 8-bit data represent 256 different shades of gray. Therefore, an 8-bit scan of an image requires eight times more space than a binary (1-bit) scan of the same image.

  • Page 66: Area Extraction

    SCANNER FEATURES Area extraction Function Extracts a rectangular area from the whole scannable area. Usage Use area extraction when you want to extract a portion of an image. For example, when you want to extract a photograph from a page, define a rectangle over the photograph, as shown below.

  • Page 67: Section Area (Multi-Area Settings

    SCANNER FEATURES Section area (multi-area settings) Function Within the scan area, you can set separate rectangular areas and define separate scanning modes, such as binary scanning, halftone scanning, or binary filters, for each area. You can specify up to six areas for one scan.

  • Page 68: Auto Photo/Letter

    SCANNER FEATURES Auto photo/letter Function The auto photo/letter mode detects photograph (halftone) areas and letter (binary) areas of the original so that the binary areas are scanned in the binary mode, and the halftone areas are scanned in the halftone mode. Note: This function is available only when the optional image processing unit is installed in the scanner.

  • Page 69: Resolution

    SCANNER FEATURES Resolution Function Sets vertical and horizontal resolution independently at 60, 75, and 100 to 800 dots per inch (dpi). The higher the resolution, the finer the detail. However, a high resolution image requires much more memory and processing time than a low resolution image. Note: When the resolution is set at more than 400 dpi, the maximum scanning width is less than 304 mm.

  • Page 70: Brightness

    SCANNER FEATURES Brightness Function Adjusts the brightness value between 1 and 255. A high brightness setting results in a lighter overall image, while a low brightness setting results in a darker overall image. Usage When scanning a dark image, the darker area may display as deep black, even though it has gray scales.

  • Page 71: Gamma Correction

    SCANNER FEATURES Gamma correction Function Selects the following gamma correction settings: Normal - emphasizes contrast slightly to improve a scanned image. Sharp - emphasizes contrast to sharpen an image. Smooth - weakens contrast to soften an image. Linear - outputs an image as scanned. User defined - loads user gamma correction curve into the scanner.

  • Page 72: Binary Filter

    SCANNER FEATURES Binary filter Function You can use the following binary filters for binary scanning: Noise elimination - eliminates independent black or white dots. Smoothing - flattens uneven dots. Thickening black lines - thickens thin lines. Edge extraction - extracts outlines of the image. Usage Use these filters as shown below.

  • Page 73: Parameter Download

    SCANNER FEATURES Parameter download Function Downloads a gamma curve and a dither pattern to the scanner. You can modify the scanned image with your gamma curve and convert it to binary using your dither pattern. Refer to your software manual for information on how to download these parameters to the scanner.
