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 in rows and columns to define the
Window of Interest.
Important: Window of Interest will shrink the field of view and therefore could cause
some symbols to be missed in dynamic applications.
