Gray Choose Gray image if your original contains actual shades of gray. B&W Choose B&W if your original contains only text, pencil or ink sketch.
B&W Gray 24 Color
4.2.2 OTHER IMAGE OPTIONS Binarization This is the process of converting a grayscale or color image to a bi-tonal image. There are several different methods of performing this conversion. Two of the options are Dynamic Threshold and Fixed Processing. Dynamic Threshold: Selecting Dynamic Threshold allows the scanner to dynamically evaluate each document to determine the optimal threshold value to produce the highest quality image.
Threshold Used to convert a grayscale image to a bi-tonal image. The value ranges from 0 to 255. A low threshold value produces a lighter image, and can be used to subdue backgrounds and subtle, unneeded information. A high threshold value produces a darker image, and can be used to help pick up faint images. Adjust the threshold setting by dragging the Threshold sliding bar to the left or right to achieve the desired threshold setting.
Brightness Adjusts the lightness or darkness of an image. The higher the value, the brighter the image. Drag the slider to the right or left to increase or decrease the brightness. Contrast Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different grayscale. Drag the slider to the right or left to increase or decrease the contrast. The range is from –100 to +100. The range is from –100 to +100.
Resolution A good control of the resolution results a good 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 greater resolution takes more time to scan, and more disk space for the scanning image. For your information, an A4 size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space.
Invert Reverses the brightness and the colors in the image. The default setting is Black on a White background. Reverse mode is White on a Black background. For color images, each pixel will be changed into its complementary color at the command of Invert.
Scan Source Choice: Auto Document Feeder: Used to scan multiple pages. Flatbed: Used to scan a single page. For example, pages from newspaper clipping, paper with wrinkles or curls. Flatbed (book): Used to scan several inside pages from book. Automatic: Allow the scanner automatically set its scan source. If Automatic is selected and there is document in both the auto document feeder (ADF) and the flatbed, then the scan source will be automatically set to ADF.
Color Adjustment Adjusts the color quality of the image so that it comes close to that of the original. This function uses default parameters to adjust the image. Normal After Color Adjustment 4.2.3 SCANNING COLOR IMAGES The following options are available for scanning color images.
4.2.4 SCANNING GRAYSCALE IMAGES The following options are available for scanning gray images. y Brightness y Contrast y Resolution y Invert 4.2.5 SCANNING B&W IMAGES The following options are available for scanning B&W images.
