ABSTRACT:
A method and an apparatus determines at least one of rank or suit of a playing card. The apparatus has at least one two-dimensional complementary metal oxide semiconductor imaging system that provides a signal when playing cards are moved over the system. The signal is a series of gray scale values that are converted into binary values. The sensed data is transmitted to a hardware component that identifies at least one of rank and suit to an external data storage device.
