1.9 - Imager Field of View and Resolution

The VS 2030’s dual field optical system may be modified based on your scanning environment. The VS 2030’s megapixel imager may be set to the following three modes:

DOT Mode (Dynamic Optimization Technology): DOT dynamically changes the resolution mode of the reader between VGA and SXGA. DOT adapts the resolution based on varying environmental criteria, and types of symbologies being scanned. This mode works best if you are working with multiple types of symbologies of varying sizes.

Note: If you are scanning mostly medium to large 2D or 1D codes, you may want to choose VGA. If you are scanning mostly small or densely packed codes, SXGA may be the better choice. It is recommended to experiment with all three modes to determine the best reading performance for your application.

SXGA Mode: In standard SXGA mode (default), the 1.3 Million Pixel imager is divided into near field and far field decode zones. In each zone the resolution is 1024 x 640 pixels. 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 field is used (small, high density symbols), the far field image can be ignored. If only the far field is used (large, lower density symbols), the near field can be ignored. Further optimization may be obtained by "windowing" the field to a smaller area. Each focal area may be narrowed by enabling the windowing feature found in section 9.3.

VGA Mode: In VGA mode (optional selection), the 1.3 Million Pixels are sampled on a 4-to-1 basis. This greatly reduces the amount of time necessary for the transfer of the image to the CPU and the resulting processing time. The trade-off for this increased speed is a reduction in resolution and working range.
