Image Scanner User's Manual Appendix Functions Note: The scanner is controlled by software. Some software does not support all of this scanner's functions. Unsupported functions are not available. The names given to functions in this manual may be different from the names used by the software. Please refer to your software manual for details. The following functions are described.
Image Scanner User's Manual ¡ Prescan Function: Scanning the whole available area at a low resolution (60, 75, or 100DPI*). Usage: Use "Prescan" when you want to obtain a quick, low-resolution scanned image. You can then adjust the scan area so that subsequent scans apply to exactly the part of the original you want to scan. *DPI stands for dots per inch and is a measure of resolution. Sometimes PPI (pixel per inch) is used instead of DPI. The higher the resolution, the finer the detail.
Image Scanner User's Manual ¡ 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 on the original using a pattern of black and white dots to represent these shades. Multi-value scanning records grays over 16, 64, or 256 levels. Usage: Use binary scanning to scan images with no gray shading, such as text or line art.
Image Scanner User's Manual ¡ Binary scanning / Threshold Function: A binary composition scanning converts every pixel on the image to either black or white. If the image contains a gray area, the threshold value determines whether the scanner records it as black or white. If the threshold value is high, the scanner records more pixels as black. If the threshold value is low, the scanner records fewer pixels as black.
Image Scanner User's Manual ¡ Halftone scanning Function: Halftone creates the illusion of gray scales by simulating shades of gray from patterns of black and white dots. Usage: Use halftone scanning when scaning an image with gray shadings such as a photograph, to be printed or displayed on a monochrome device, such as a laser printer. Halftoning saves memory, so it is convenient for filing a large amount of image data.
Image Scanner User's Manual ¡ 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, 8-bit data represents 256 different shades of gray. Note that the multi-value scanning uses more memory and disk space. For example, 8-bit scanning needs 8 times space more than binary (1-bit) scanning of the same scan area.
Image Scanner User's Manual ¡ Area extraction Function: To extract a rectangular area from the whole scannable area. Usage: For example, if you want to extract a photograph from a page, define a rectangle over the photograph, as shown below. The position of the area is decided by setting the X and Y co-ordinates of the leftupper corner of the rectangle. The size is decided by setting the vertical and horizontal lengths, which can be set separately.
Image Scanner User's Manual ¡ Section area (Multi area settings) Function: Within the scannable area, you can set rectangular areas and define scanning modes such as binary scanning, halftone scanning, or binary filter etc. for each area. Six areas can be set for one scan. These areas can be piled on top of one another and the last defined area is valid. Note: If six areas are piled, depending on how they are piled, scanning may not result in the correct mode.
Image Scanner User's Manual ¡ Auto photo/letter Function: This mode detects photo (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. If binary areas and halftone areas are not separated clearly, segmentation may not be achieved .
Image Scanner User's Manual ¡ Resolution Function: To set vertical and horizontal resolution independently at 60, 75, and 100 to 800 dots per inch. The higher the resolution, the finer the detail. However, a high resolution image requires much more memory space and processing time than a low resolution image. Note: If the resolution is set at more than 400 dpi, the maximum scanning width is less than 304 mm.
Image Scanner User's Manual ¡ Brightness Function: To adjust the brightness value between 1 and 255. A high brightness setting results in a lighter overall image. A low brightness setting results in a darker overall image. Usage: When scanning a dark image, the darker area may appear as deep black although it has gray shades. In this case, increase the setting and shades of gray appear. Conversely, if a lighter image becomes pure white, decrease the setting.
Image Scanner User's Manual ¡ Gamma correction To select 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: Your own gamma correction curve is loaded into the scanner. Usage: Select one of them depending on your original and output device.
Image Scanner User's Manual ¡ Binary filter Function: You can use 4 binary filters; noise elimination, smoothing, thickening black lines and edge extraction in 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: For example, use filters at following cases.
Image Scanner User's Manual ¡ Parameter download To download a gamma curve and a dither pattern to the scanner. You can modify the scanned image with your gamma curve and binalize it with your dither pattern. Refer to your software manual for how to download these parameters to the scanner. ¡ Document size detection The scanner detects the width and length of a document and sends them to the host computer.
Image Scanner User's Manual Options ¡ Red lamp unit You can use the optional red lamp unit to skip the OCR red images. Replace the lamp unit with the optional red lamp unit as follows. Warning: E E Never change the lamp unit with the scanner plugged in. The lamp becomes very hot. Wait for about five minutes aftter turning the power off to let the lamp cool off. 1. Initialize the scanner to return the carriage to its original position. 2. Turn the power off and disconnect the power cord. 3.
Image Scanner User's Manual ¡ Data compression unit Using an optional data compression unit, it is possible to compress the scanned image data by methods known as MH, MR, and MMR. This saves memory capacity. ¡ Video interface unit The optional video interface unit provides a video interface connector. ¡ Image processing unit The optional image processing unit adds the following image processing functions. Dynamic threshold: The scanned image is automatically binalized by an appropriate threshold.
