Scanner with control over context switching of exposure modes

A method, comprising:

• controlling cameras of a scanner for capturing a code in a first number of image frames during a short exposure mode of operation for the cameras and during a transaction at a transaction terminal;
• and
• controlling the cameras for capturing the code in a second number of image frames during a long exposure mode of operation for the cameras and during the transaction;
• wherein controlling the cameras during the long exposure mode of operation for the cameras further includes controlling a timing for activating the cameras during the long exposure mode of operation for the cameras based on a state of illumination associated with illumination sources of the scanner.

A scanner, comprising:

• cameras;
• a processor;
• a non-transitory computer-readable storage medium comprising executable instructions;
• the executable instructions when executed by the processor from the non-transitory computer-readable storage medium cause the processor to perform operations comprising:
• setting a first number of image frames that is to be captured by the cameras during a short exposure mode of operation for the cameras based on a configured ratio setting;
• setting a second number of image frames that is to be captured by the cameras during a long exposure mode of operation for the cameras based on the configured ratio setting, wherein the first number of the configured ratio setting is greater than the second number of the configured ratio setting;
• and
• controlling activation of the cameras during the long exposure mode of operation for the cameras and during a transaction at a transaction terminal based on a falling edge interrupt received for illumination associated with illumination sources of the scanner.
