PLAYING CARD IMAGING TECHNOLOGY WITH THROUGH-THE-CARD VIEWING TECHNOLOGY

摘要

A method of reading suit and rank of playing cards is enabled on a system for controlled provision of image content of faces of a playing card that has:
e) a support surface for playing cards;f) a source of infrared radiation;g) an infrared sensitive camera; andh) a processor.

The infrared sensitive camera positioned to capture infrared radiation transmitted through the playing cards and transmit information based on the captured radiation to the processor; and the processor configured to provide suit and rank information of a playing card through which the infrared radiation was transmitted.

1. A method of reading information from a playing card while an image face of the playing card is hidden by a visible-light-opaque back comprising:
an infrared-sensitive camera positioned over the playing card back receives infrared information passing through the playing card; a filter on the camera filtering out at least some visible and some infrared radiation, allowing a defined range or wavelength of infrared radiation into the camera; the camera capturing infrared radiation within the defined range of radiation and transmitting signals based on the captured radiation; a processor receiving the transmitted signals and executing code to define patterns in the captured radiation; and the defined patterns including image content of suit and/or rank on the image face of the playing card.
