24.2 Image type classification

A.

OUTLINE

• A scanned image type is classified as text, dots, solid or chroma. 
• After the classification, gamma curve used for writing the image is changed to the appropriate one for the

image type.

• The image classification function works "Text/Photo", "Text", or "Map" is selected in the original setting

menu.

• The function does not work when "Photo" is selected.
