Increasing this setting will make the image clearer and make light information more visible. The options range from -50 to 50. The default is 0. NOTE: This is only available for Conversion quality: Best and Conversion quality: Normal. Threshold - aids in controlling the level at which a pixel is considered black or white. Decreasing this setting will make the image appear lighter, and can be used to subdue background noise. Increasing this setting will make the image appear darker, and can be used to help pick up light information. The options range from 0 to 255. The default is 90. NOTE: This is only available for Conversion quality: Draft and Conversion quality: Normal. • Filters: Noise - (none) - Lone Pixel: reduces random noise by converting a single black pixel to white when it is completely surrounded by white pixels or by converting a single white pixel to black when it is completely surrounded by black pixels. - Majority Rule: sets each pixel based on its surrounding pixels. The pixel will become white if the majority of the surrounding pixels are white and visa versa. 3-16 No Noise Filter Used Lone Pixel • Filters: Image - (none) - Halftone Removal: enhances dot matrix text and images made with halftone screens (e.g. newspaper photographs).
