Abstract
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.

1-8. (canceled)
A method implemented by a processor in an optical code scanner, the method comprising:
- reading optical codes on items presented to the optical code scanner using images captured from a plurality of image capture devices;
- storing a first set of statistics for each of the plurality of image capture devices when it is determined a first data period is active;
- starting a second data period after it is determined the first data period has expired;
- storing a second set of statistics for each of the plurality of image capture devices when it is determined the second data period is active;
- and
- transmitting a failure alert indication for a first of the plurality of image capture devices when the second set of statistics are below the first set of statistics for the first of the plurality of image capture devices by a predetermined amount.
