A device for forming a random set of playing cards comprises a card in-feed area, a shuffling system, a card removal area, and a card reading system located within the device, the card reading system employing a complementary metal-oxide semiconductor (CMOS) sensor and a hardware component, the hardware component capable of converting signals from the CMOS sensor into vector sets and comparing the vector sets to known vectors to determine rank and suit.
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 gen
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; andcorrelating 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. 2. The method of claim 1, wherein both rank and suit are determined utilizing the logic control circuit. 3. The method of claim 1, wherein the image sensor is selected from the group consisting of a complementary-metal-oxide-semiconductor sensing system and a contact-image-sensor sensing system. 4. The method of claim 3, wherein the complementary-metal-oxide-semiconductor sensor is a color sensor. 5. The method of claim 4, wherein the complementary-metal-oxide-semiconductor sensor is a two-dimensional sensor. 6. The method of claim 1, wherein the acquired image data is a vector set. 7. The method of claim 1, wherein the converted reference data is a vector set. 8. The method of claim 1, further comprising the step of template matching to determine at least one of rank and suit. 9. The method of claim 1, wherein the image sensor comprises a black and white complementary-metal-oxide-semiconductor sensor. 10. The method of claim 9, wherein the image sensor outputs gray scale values. 11. The method of claim 10, wherein the gray scale values are outputted in at least one of an 8- and 16-bit format. 12. The method of claim 1, wherein the binary values are inverted. 13. The method of claim 1, wherein the correlating step comprises using template matching to determine at least one of suit and rank. 14. The method of claim 1, further comprising activating the image sensor in response to a signal received from a card present sensor. 15. The method of claim 1, wherein the logic control circuit is selected from the group consisting of a field-programmable gate array and an application-specific integrated circuit. 16. The method of claim 1, further comprising providing a green light source for acquiring unknown card images. 17. The method of claim 1, further comprising the step of comparing unmatched images of shape. 18. The method of claim 1, further comprising the step of providing a light source for acquiring unknown card images. 19. The method of claim 18, wherein the light source is directed to the card face by means of at least one of a mirror and a lens.
