Method and apparatus for assessing the health of an image capture device in an optical code scanner

摘要

An image based optical code scanner is presented that determines the health of each of a plurality of image capture devices located within the optical code scanner. The optical code scanner first determines a baseline performance for each of the image capture devices by capturing statistics for each of the image capture devices during item scanning operations. The optical code scanner then periodically determines the current performance of each of the image capture devices and compares it with the baseline performance. An alert message is generated if the current performance of any image capture device falls below its baseline performance.
