Theory of Operation
During image capture:
1.
The image sensor array in the embedded SE4500 imaging engine captures an image of the bar code
through the engine’s optical lens. If necessary, the engine automatically adjusts illumination, exposure, and
other parameters to obtain the best quality image.
2.
The imaging engine sends the image to the DS457 CPU.
3.
The DS457 CPU processes the image to identify the target bar code(s), decodes them, and transmits the
decoded data to the host.
Set various parameters provided in this guide to adjust the performance of the DS457 to match the application
or desired usage profile.
