SCANNER FEATURES

A-10

Auto photo/letter

Function

The auto photo/letter mode detects photograph (halftone) areas and

letter (binary) areas of the original so that the binary areas are

scanned in the binary mode, and the halftone areas are scanned in

the halftone mode.

Note: This function is available only when the optional image

processing unit is installed in the scanner. When binary areas

and halftone areas are not separated clearly, segmentation

may not be achieved.

Usage

Scanning of an original that includes binary images such as letters

and halftone images such as photographs.
