Three choices are available in the TWAIN source: Color mode, Gray mode, and Black/White mode. Gray mode Select Gray mode for images that contain 256 shades of gray. Color mode Select this for 24-bit color images. Line Art mode Select Line Art for texts and illustrations that contain only black/white without gray shading. Filter Filters are provided to produce dropout effects, i. e. , to drop the part of the image that is in a color difference from the specified filter. Four options are available: True gray, Red, Green, and Blue filter. Green Filter True Gray Filter Blue Filter Red Filter Please note that the filter option will be unavailable if you select the "Color mode" in Scan Mode. The disablement of the filter is shown as follows. 6 Resolution The resolution is measured in dots per inch (dpi), which is used to represent the image detail in a given area. Generally, the higher the resolution is, the sharper and higher the quality of the scanned image gets. However, in some cases, high resolution is not necessary because resolution is determined or limited by many factors: image type, the original image's resolution, the output device's resolution, the available memory space in your hard disks, etc. Pointer Edit box You can adjust the resolution by dragging the pointer to the desired resolution , directly key the value in the Edit box, or choose the value by clicking on the pull-down button. Brightness Brightness refers to the intensity of light reflected from or transmitted through an image. You can either drag the pointer, key the value into the Edit box to change the value, or choose the value by clicking on the pull-down button. Contrast Contrast refers to the differences in the brightness between the light areas and the dark areas of an image. The larger the contrast value, the higher the differentiation between the light and the dark areas. You can either drag the pointer, key the value in the Edit box to change the value, or choose the value by clciking on the pull-down button. 7 Control Buttons in Main Page Scan Button Click the Scan button to perform the final scan and send the result to the destination determined by you. Prescan Button Click the Prescan button to perform a prompt low-resolution scan. The prescan image will be displayed in the Preview window. Help Button Click this button to get on-line help. Exit Button Close this TWAIN source window. Reset Button Click this button to return to the default setting. 8 Advance Page While including the basic functions of the Main page, the Advance page also encompasses image enhancement tools that can be used to compensate for any color distortion of the scanned image. The Advance page is illustrated as follows. Preview Window Image Enhancement Tool Size Press the right mouse button in the preview window, and a rectangle box with a list of sizes will pop-up. Please select one of them and press "Scan" directly. Scan Control Tools ( the same as Main page) Image Enhancement Tools ­ Image Box Mirror Descreen HSV Auto Color Control Color Correction Zoom Invert Gamma Tone Adjustment 9 Zoom The Zoom command allows you to enlarge the view of an image in the Preview window. However, the zoom function can only enlarge the image view with one defined scale. To disable zoom in: After magnifying the view, click the Zoom command again to reduce the view to its original size. NOTE: When zooming in, a vertical scroll bar and/or a horizontal bar will appear to let you scroll through the entire image. Mirror Mirror command lets you change the horizontal orientation of a prescan image to one that mirrors the current orientation of the image view across a vertical imaginary line. To mirror an image: Click the Mirror command in the Image box. Invert The Invert function enables you to make a positive view of a scanned image negative or to make a negative image positive. By applying this command, the brightness value of each pixel will change to an inverse value on 256-color scale. To invert an image: Click the Invert command from the Image box after applying the Prescan function. 10 Descreen Descreen filter is used to eliminate the moire patterns (wavelike lines) from the images. As the images are scanned directly from screen-print media (like newspapers or magazines), you should notice that the scanned images usually come with wavelike patterns and banding lines. As long as the scanning resolution is not set very high, you can apply this function to remove those annoying effects. [. . . ] (If the "Prescan" box is not checked, you can omit steps 3 & 4. ) 4. The scanner performs the auto area detect function (please first check the "Area detection" option) to define the actual area of your scanned image in the preview window. The final scanning starts to run and the scanned result will be sent to the destination (e. g. , File, Application, Mail, Clipboard, Fax or Disk), which depends on your choice. For the purpose of performing this step, please ensure that the "Scan and send to destination" option is checked. [. . . ]
