1.11 - Imager Field Selecon and Resoluon
The CR3500’s dual eld opcal system may be modied based on your scanning environment.
The 1.3 Million Pixel imager is divided into wide eld and high density decode zones. In each zone the resoluon is 1024 x
640 pixels (see Figure 1.25).
If only the high density eld is used (small symbols), the wide eld image can be ignored. If only the wide eld is used
(large symbols), the high density eld can be ignored. Further opmizaon may be obtained by "windowing" the eld to
a smaller area. BY DEFAULT, THE CR3500 DECODES ONLY THE WIDE FIELD.
