Card shuffling apparatus and card handling device
First Claim
Patent Images
1. A method of determining at least one of rank and suit of a playing card in a card handling device, comprising:
- training an imaging system of the card handling device by reading at least one reference set of card ranks and a set of card suits utilizing an image sensor of the imaging system and generating reference data;
converting the reference data to reference binary values utilizing a logic control circuit;
storing the reference binary values in non-transitory memory;
capturing acquired image data from an unknown card face utilizing the image sensor;
converting the acquired image data into unknown card face binary values utilizing the logic control circuit; and
correlating the unknown card face binary values to reference binary values utilizing the logic control circuit to determine at least one of rank and suit of the unknown card face.
