Blur Filters; Sharpen Filters - Microtek ArtixScan 4500t Reference Manual

Blur filters

The Blur filters eliminate noise in the parts of the image where significant color
transitions occur. These filters decrease the contrast between adjacent pixels,
making the image appear hazy and out of focus.
• Blur smooths out the transitions by lightening pixels next to the hard edges of
defined lines and shaded areas.
• Blur More produces an effect three or four times stronger than Blur.

Sharpen filters

The Sharpen filters do the opposite of the Blur filters and increase the contrast
of adjacent pixels, making images appear sharper and more focused.
Both Sharpen and Sharpen More filters improve clarity, with the Sharpen More
filter having a stronger sharpening effect than the Sharpen filter.
