1.10 - Imager Field Selection and Resolution

The CR2500’s dual field optical system may be modified based on your scanning environment.

The 1.3 Million Pixel imager is divided into wide field and high density decode zones. In each zone the resolution
is 1024 x 640 pixels (see Figure 1.26).

If only the high density field is used (small symbols), the wide field image can be ignored. If only the wide
field is used (large symbols), the high density field can be ignored. Further optimization may be obtained by
"windowing" the field to a smaller area.

BY DEFAULT, THE CR2500 DECODES ONLY THE WIDE FIELD.
