1. A method of automatically generating a calibration file for a card handling device, the method comprising: capturing, with an imaging device of the card handling device, a raw image from at least a portion of a card passing through the card handling device from an input tray to an output tray of the card handling device; and using a processor of the card handling device, automatically generating and storing a calibration file in memory of a main control system of the card handling device without user input, the calibration file being unique to the card handling device for a specific deck that includes the card such that the card handling device is trained for the specific deck during a subsequent card recognition mode, wherein automatically generating the calibration file comprises: identifying at least one parameter associated with a rank area around a rank of the at least a portion of the card; identifying at least one parameter associated with a suit area around a suit of the at least a portion of the card; and storing the at least one parameter associated with the rank area and the at least one parameter associated with the suit area in the calibration file.
