Binarization This is the process of converting a grayscale or color image to a bi-tonal image. There are several different methods of performing this conversion. Two of the options are Dynamic Threshold and Fixed Processing. Dynamic Threshold: Selecting Dynamic Threshold allows the scanner to dynamically evaluate each document to determine the optimal threshold value to produce the highest quality image. This is used to scan mixed document containing faint text, shaded background, or color background with a single setting. If Dynamic Threshold is selected, Threshold, Brightness, and Contrast are not available.

Fixed Processing: Used for black-and- white and other high contrast documents. A single level is set to determine the black- and-white transition. The threshold is programmable over the entire density range. Fixed Processing sets Contrast to 0. If Fixed Processing is selected, Contrast is not available.

Threshold Used to convert a grayscale image to a bi-tonal image. The value ranges from 0 to

255. À low threshold value produces a

lighter image, and can be used to subdue backgrounds and subtle, unneeded information. A high threshold value produces a darker image, and can be used to help pick up faint images. Adjust the threshold setting by dragging the Threshold sliding bar to the left or right to achieve the desired threshold setting. 200 dpi, 200 dpi, Threshold:80, Threshold:170, Brightness: 0 Brightness: 0

Brightness Contrast Adjusts the lightness or darkness of an image. The higher the value, the brighter the image. Drag the slider to the right or left to increase or decrease the brightness. The range is from -100 to +100. Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different grayscale. Drag the slider to the right or left to increase or decrease the contrast. The range is from -100 to +100. Brightness: -50 Brightness: 0 Brightness: +50 Contrast: -50 (Normal) Contrast: O Contrast: +50 4-10

Resolution A good control of the resolution results a good detail of an image that scans. The resolution is measured by dots per inch (dpi). Normally, the greater the dpi number, the higher the resolution and the image file size. Be aware that greater resolution takes more time to scan, and more disk space for the scanning image. For your information, an A4 size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space. A higher resolution (usually means over 600 dpi) is only recommended when you need to scan a small area at True Color mode. Choose a resolution value from the drop down list. The default value is 200 dpi. Available resolutions are 75, 100, 150, 200,300, 400 and 600. Or you may choose your desired value by clicking the box in the right side of the drop down list and press the arrow key to select your desired value and then click the Add button to include it in the drop down list. 4-11

The Compression tab allows you to compress your scanned image and choose the level of compression. Bi- tonal images are normallÿ compressed using CCITT standard called Group 4 (G4). Color and grayscale images are often compressed using JPEG technology. Move the JPEG Quality slider to the right or left to increase or decrease the level of compression. Note the greater the compression level, the lower image quality. Default is 50%. Note that the compression depends on your image editing application. 1f your image editing application does not support the type of compression format, then either a warning message will appear or the image quality of the compressed file will not be acceptable. JPEG (Joint Photographic Editor Group). This group developed and lent their name to a file compression standard for color and grayscale images that is widely used by scanners, and software applications. On Microsoft Windows-based systems, a file with the extension .jpg has normally been compressed using this standard. For scanning color or gray images, the following compressions are available: . None + JPEG For scanning B&W images, the following compressions are available: . None . Ga 4-15

Color Dropout tab allows you to drop either of the red, blue, or green color in your scanned image. If your image contains red color watermark or background, choose the R (Red) channel then any red watermark or background will be removed. This feature is used to sharpen your text when using OCR (Optical Character Recognition) software. Note that this function supports only black & white and gray images. Therefore, be sure to choose any black & white or gray image type while applying this function. Ie | Compesion Cor Dropont |Papsr | Qyéons | Gting | Tnformeten |

Advanced Processing provides two options that can adjust your scanned image in the best optimal result. Filter This value is used to determine the color Threshold which will be dropped out. A lower value will drop more of the selected color out, while à higher value will leave more of the selected color in. Background The pixel which is higher than the Level background value will be adjusted to the lightest point. Adjust the value for both the Filter Threshold and Background Level to produce the best optimal result. Example, slightly adjusting the background value makes your text more clear. topo Original 4-18

Cropping allows you to capture a portion of the document being scanned. Choice: Automatic, Fixed to Transport, EOP (End of Page) Detection. Options Description Automatic Automatic adjusts the cropping window according to different document sizes. Use this option for batches of mixed-sized documents. Fixed to Transport This feature allows you to define the area or zone to be imaged. Use for batches of same-sized documents. If you select this option, you can use the arrow keys to define the x and y offset values, width and length to redefine your scanned area. The Display window will show image placement as you change the values. EOP (End of Page) Detection This feature allows you to define the area or zone to be imaged.

OverScan Overscan allows you to add a specific margin at top and bottom or right and left (Options vary based on the type of scanner) of the edge of the image. This is used to reduce possible corner clipping on the skewed images and often applied to a batch of skewed document to be scanned in the auto document feeder. Select a value between 0 and +5 mm. Note the overscan result will not be shown in the Display window and that the availability of the function varies based on type of scanner. 4-24

Multi-Feed Detection Multi-Feed Detection allows you to detect overlapped document that go through the auto document feeder. Multi-Feed usually occurs due to stapled documents, adhesives on documents, or electro-statically charged document. Note: The availability of the function varies based on type of scanner. Additional Length Detection Additional Length Detection allows you to define the length of document being multi-fed. This value indicates the additional length exceeding your scan area. The Display window will show the size of the document as you change the value. A value of 0 indicates no additional length detection.
