An analysis and decode module is described. A barcode reading system may include an image sensor system package and a separate image decoding system. The image sensor system package may provide input to the image decoding system through an interface. The input may include a captured image, image capture settings, and an operation list. The image decoding system, using the analysis and decode module, may perform one or more operations identified in the operation list on the capture image. The image decoding system may then output information to the image sensor system package using the interface. The output may indicate whether the image decoding system was able to decode a barcode and how the image sensor system package may modify the image capture settings to produce an image more suitable for decoding. The image sensor system package may then determine new image capture settings for capturing a new image.
