Bi-tonal images are normally 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. If 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. 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 G4 4-17 The Compression tab dialog box 4-18 User's Manual 4. 4 The Color Dropout Tab 4. 4. 1 Color Dropout Selection 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. The Color Dropout dialog box 4-19 4. 4. 2 Other Color Dropout Options Advanced Processing provides two options that can adjust your scanned image in the best optimal result. Filter Threshold This value is used to determine the color which will be dropped out. A lower value will drop more of the selected color out, while a higher value will leave more of the selected color in. The pixel which is higher than the 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. Background Level Example, slightly adjusting the background value makes your text more clear.
