7.2 Sharpness Function
7.2.1 What is sharpness?
Sharpness is a process to improve the readability of scanned image data.
❏ When sharpness is specified for 256-level gray scale image data, the readability of small
characters is improved by emphasizing the edges.
❏ When sharpness is specified for bitonal (black/white) image data, the readability of
characters is improved because the edges of characters on dark backgrounds are
emphasized to separate the character from the background.
• For your reference, the original check for the examples above for bitonal data is shown
below without sharpness applied.
However, the sharpness processing may have the opposite effect for bitonal (black/white) data
with a finely detailed background:
