Window of Interest (WOI)
The active pixel area of the image sensor is called the Window of Interest (WOI).
The WOI allows you to select an area of the field of view in which the desired
symbol is located.
The programmable WOI increases decode speed, improves threshold, and makes
it easy to select specific symbols from among several in the field of view. You
provide the upper-left pixel location and the size of the window in rows and
columns to define the WOI.

• Default: Outer LED only
• Options: 1 = Inner white LED only

IMPORTANT
WOI shrinks the field of view and therefore could cause some symbols to be
missed in dynamic applications.
