Window of Interest

Window of Interest

The active pixel area of the image sensor is called the Window of Interest (WOI). The WOI
allows the user to select an area of the field of view in which the desired symbol is located.
The programmable window of interest increases decode speed, improves threshold, and
makes it easy to select specific symbols from among several in the field of view. The user
provides the upper-left pixel location and the size of the window to define the Window of
Interest.
Caution: Window of Interest will shrink the field of view and therefore could cause symbols
to be missed in dynamic applications.
