[Problem] An information processing device, information processing method, and program that can perform stable position detection even in an environment in which a detection wavelength is included in external light are provided. [Solution] An information processing device including: a control unit that performs position detection of an object, on which a light emitting unit or a reflective material is provided, on the basis of a captured image acquired by imaging of emitted light or reflected light of the object in a direction facing a side, on which the light emitting unit or the reflective material is provided, of the object, wherein the control unit adjusts algorithm for the position detection of the object according to an illuminance detection result of external light including at least a wavelength of the emitted light or the reflected light.

An electronic gaming table executes player-versus-player playing card games. The gaming table has a display screen where at least one random virtual playing card is virtually delivered to individual player positions for each of the multiple players. The electronic gaming table includes the display screen, a processor associated with memory, player input controls and a playing card masking element at each player position. The playing card masking system at each player position is positioned over an individual position that is a portion of the display screen where the processor directs delivery of the at least one random virtual playing card virtual face down. The playing card masking system includes a three-dimensional element having a visible light transmissive line of sight between the individual position and a player at the individual player position, while excluding visible light transmission to player positions across from or adjacent to the individual player position.

A gaming table system for executing gaming events with physical playing cards or two dice having: a support layer with multiple functional layers, the multiple functional layers comprising a bottom table top layer, an intermediate padding layer and a top layout layer; beneath the support layer is an array of infrared-sensitive cameras having overlapping focal areas that cover all areas on a bottom surface of the support layer where playing cards are or dice are placed face down on the top layout layer during the gaming events; a source of infrared LED lighting having a projection area that covers all areas on the bottom surface of the support layer where playing cards are placed face down on the top layout layer; the array of infrared-sensitive cameras having a communication link to a processor; and the support layer being translucent to infrared emissions from the source of infrared LED lighting.

Card-handling devices may include an input area sized and shaped to receive cards and an output area for outputting at least some of the cards. A defect detection system may be located along a card path downstream from the input area. The defect detection system may include an emitter positioned and oriented to direct radiation toward a major surface of a card as the card moves along the card path. A detector may be positioned and configured to detect the radiation emitted by the emitter and reflected from the major surface of the card as the card moves along the card path. A controller may be operatively connected to the detector and configured to correlate a signal from the detector with an identification of a degree to which the major surface of the card has deviated from a reference plane.

Card-handling devices may include an input area sized and shaped to receive cards and an output area for outputting at least some of the cards. A defect detection system may be located along a card path downstream from the input area. The defect detection system may be configured to scan at least one card to determine whether at least one characteristic of the at least one card has been modified beyond a predetermined limit or whether the at least one characteristic of the at least one card is within the predetermined limit. A diverter may be configured to divert the at least one card from the card path when the at least one characteristic of the at least one card has been modified beyond the predetermined limit and enable the at least one card to continue on the card path when the at least one characteristic of the at least one card is within the predetermined limit.

A game board device is provided for carrying and identifying game pieces that are divided into different piece types. The game board device includes a board, a plurality of optically identifying modules, and a processing module electrically coupled to the optically identifying modules. The optically identifying modules respectively correspond in position to detection regions of the board. Each of the optically identifying modules includes a light emitter that can emit light toward the corresponding detection region and a light receiver that can receive light reflected by the corresponding detection region. When any one of the detection regions is in an unoccupied mode, the corresponding optically identifying module can emit an unoccupied signal. When any one of the detection regions is in an occupied mode, the corresponding optically identifying module enables an identification signal that corresponds to the piece type of the corresponding game piece to be emitted therefrom.

A portable system and method for identifying roulette wheel biases includes a frame member rotatably attachable to a roulette wheel proximate a turret support, a ball-drop tube slidably engaged to the frame member and a laser positioned to measure at least a bounce height of a roulette ball dropped through the ball-drop tube onto selective areas of the roulette wheel. One or more sensors may be positioned to trigger the laser responsive to a roulette ball being dropped through said ball-drop tube. Software analyzes the bounce height to determine dead spots and hot spots on the roulette wheel. Sound waves may also be measured to determine dead spots and hot spots.

Embodiments of a radio frequency identification (RFID) reader are provided herein, which include an RFID interrogator; a detection surface for a game piece, the detection surface comprising a plurality of reader antennas in a geometric arrangement; and antenna switching circuitry coupled between the RFID interrogator and the plurality of reader antennas; wherein the antenna switching circuitry is configured to consecutively activate each one of the plurality of reader antennas for at least a detection time window, and wherein the RFID interrogator is configured to: for each reader antenna, detect whether a response signal is received by the reader antenna during the detection time window, and determine a geometric orientation of the game piece based on a subset of reader antennas that received the response signal.
