Abstract
Abstract A system automatically monitors playing and wagering of a game. A table monitor in a chip tray automatically images the activity occurring at a gaming table. Periodic comparison of the images identify wagering, as well as the appearance, removal and position of cards and other game objects on the gaming table. The chip tray may also include a chip tray reader that automatically images the contents of a chip tray, to periodically determine the number and value of chips in the chip tray, and to compare the change in contents of the chip tray to the outcome of game play for verifying that the proper amounts have been paid out and collected. The system can produce measurements relevant to providing automated security, real-time accounting and a basis for automatically allocating complimentary player benefits.
