5. SCANNER OPERATION For TWAIN Application AV500U allows you to operate the scanner from within a TWAIN or plug-in software application. As the scanner driver is not a standalone software, it has to be started from within a TWAIN/ISIS*compliant software application and then the scanner driver is able to scan and load the image to your computer. The command to start the scanner driver may vary due to different software applications.
6. Select the scanning method you want to use on the Scan Method drop-down menu. 7. Select the mode you want to use for your scans on the Image Type drop-down menu. 8. Select a scanning resolution on the Resolution drop-down menu. 9. Select the settings for the scanning features (e.g., Sharpen, Descreen, etc.) that you want to use. 10. Click on the Preview or Scan button to preview or scan your document(s).
6. USER INTERFACE 6.1 SCAN METHOD Select how you want to scan on the Scan Method drop-down menu. ADF/One-page—use this setting if you are using the automatic document feeder (ADF) to scan a single-page document at a time. ADF /Multi-page—use this setting if you are using the automatic document feeder (ADF) to scan batches of single-page document at a time. Flatbed—use this setting if you are using the flatbed to scan one page at a time.
6.2 DETERMINING YOUR RESOLUTION A good control of the resolution results in 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, and 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.
6.3 SELECTING A PROPER IMAGE TYPE Select image type through the mode from the scanner user interface for your own purpose. Each image type described as follows: Line art (Black and White) 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.
Lineart Image *Pixel: A combination of two words: picture and element, a pixel is a single dot on a computer display or in a digital image.
Halftone In addition to the black and white display, Halftone simulates gray scale 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.
8-Bit Gray A single-channel image gray. An 8-bit scanner shades of gray between this option if you are consists of at least 256 shades of produces a grayscale image with 1024 pure black and pure white. Choose scanning black-and-white photographs. With 8 bits of color information per pixel, the file size of an image is eight times larger than a Black and White image and 1/3 the size of a 24-Bit Color image.
8-Bit Color An 8-Bit Color image provides 256 color hues in the image. The file size of a 256 color image is 1/3 the size of a 24Bit Color image.
24-Bit Color A 24-Bit Color image consists of three 8-bit color channels. The red, green, and blue channels are mixed together to create a combination of one billion colors, which give a more true-to-life quality to the image. Choose 24-Bit Color if you are scanning color photos.
6.4 ENHANCING YOUR IMAGE Brightness: Adjusts the lightness or darkness of an image. The higher the value, the brighter the image.
6.5 CONTRAST Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different gray scales.
6.6 INVERT IMAGE The invert command reverses the brightness and the color in the image. For color images, each pixel will be changed into its complementary color at the command of Invert.
6.7 MIRROR Click on the Mirror button to reverse the image (create a mirror image).
