3. The Mac Plug-in user interface will pop up on the screen. 4. Place the document upside down on the document glass with the text facing away from you. 5. Click the Preview or Scan button to preview or scan your document or image. Figure 4-1 Mac Plug-in user interface *TWAIN: Stands for Technology Without An Interesting Name, an industry-standard protocol which exchanges information between the application and image acquisition device such as scanners.
PC Users 1. Open your application and chooseSelect Sourcefrom the File menu. If theSelect Source command is not available from the File menu, see the user guide of your application to learn how the TWAIN link is used. 2. A dialog box appears containing the different TWAINsources for you to choose from to bring an image into your application.

4.2 USING AVISION SCANNER DRIVER USER INTERFACE 4.2.1 CHOOSING YOUR SCANNING SOURCE Two scanning sources are provided - flatbed as well as transparency. However, if you have not installed the transparency ,kit please leave the source to the flatbed option.
4.2.2 DETERMINING YOUR RESOLUTION A good control of the resolutionresults a satisfactory 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 the greater resolution takes more time, memory and disk space, therefore, up to a certain degree of dpi, the resolution will not visually be improved, on the contrary, it makes your files more unmanageable.
Tips: 1. 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 recommended only when you need to scan a small area at True Color mode. 2. You can also refer to the following table to choose a proper resolution while applying your image to other application.
4.2.3 SELECTING A PROPER IMAGE TYPE Select image type through the mode from the scanner user interface for your own purpose.
Each image typeis described as follows: Line art LineArt presents the image in black and white only and there are no intermediate shades of gray in between. That means each pixel of the image is 100% black or 100% white.LineArt is the best choice of image type if you want to scan text, pen or ink drawing. Since only 1-bit of black or white information is required for each pixel*, the disk space required for saving lineArt image is only about 1/24 of that required to save 24-bit true color images.
Halftone In addition to the black and white display, Halftone simulates grayscale by using different size of dots. Particularly when you view the image at a certain distance, it looks very closely like a gray image yet it consumes the least disk space. Halftone is the picture that we usually see in newspapers or magazines. Since Halftone is one type of black and white image, the disk space required to save a halftone image is 1/24 of that required to save a 24-bit true color image.
Gray (4096 levels gray scale/Internally) A single-channel image consists of at least 256 levels of shades of gray in an image. A 12 bits scanner produces a Gray image with 4096 shades of gray between pure black and pure white. Gray is the best choice of image if you wish to scan a black and white photograph. With 12 bits of color information per pixel, the disk space required to save a gray image is eight times more than lineArt and 1/3 of that required to save a 24-bit true color image.
256 Colors The 256 colors image provides 256 levels of color hues. The disk space required to save an image in 256 colors is 1/3 of that required to save a 24-bit true color image. Figure 4-8 A 256 Color Image True Color A 36-bit Color image consists of three 12-bit color channels. The red, green, and blue channels are mixed together to create a 36 combination of one billion(2 ) colors which give a more true-tolife quality to the image. True Color is the best choice if you want to scan a color photo.
4.2.4 ENHANCING YOUR IMAGE Brightne s Contrast Gamma Highlight Shadow Hue Intensity Saturation Brightness: Decrease your Brightness Adjusts the lightness or darkness of an image. higher the value, the brighter the image.
Contrast: Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different gray scales. Decrease your Contrast Gamma: Gamma Value: 1.0 Normal Increase your Contrast Adjusts themidtone of the image without losing details of the lightest and the darkest areas. Gamma Value: 1.4 4-14 Gamma Value: 2.
Highlight/Shadow: Highlight refers the lightest point in a scanned image while shadow refers the darkest point. Using Highlight and Shadow tool together allow you to extend the range of color and reveal more details in a gray or color image.
Hue: Adjust the hue up to 360§ by clicking your desired color on the Color wheel or clicking the up or down arrow button. (Note the level of intensity for the color will be changed simultaneously when the hue adjustment is made). The Color Wheel Intensity: Adjust the color strength by clicking the Up or Down arrow button. Saturation: Adjust the saturation level for the color by clicking the Up or Down arrow button. The level of saturation decides if the color is pale or rich.
