1.10 - Imager Field of View and Resolution

The CR2’s dual eld optical system may be modied based on your scanning environment. The CR2’s megapixel imager

may be set to the following three modes:

The 1.3 Million Pixel imager is divided into near eld and far eld decode zones. In each zone the resolution is 1024 x 640

pixels (see Figure 1.25). In this mode of operation the reader utilizes the highest resolution creating the widest working

range on bar code and 2-dimensional symbols of all densities. The trade-off is the amount of time the reader spends

processing the image. This time can be reduced by optimization functions:

If only the near eld is used (small symbols), the far eld image can be ignored. If only the far eld is used (large

symbols), the near eld can be ignored. Further optimization may be obtained by "windowing" the eld to a smaller area.

Each focal area may be narrowed by enabling the windowing feature found in section 5.2.
