Disclosed is a method of determining a dart game player to participate in a play session which imposes a play time constraint to two or more devices, the method being performed by a dart game server, the method including: receiving first play result information from a plurality of devices that participated in a first play session conducted during a first time period; and determining, based on the first play result information, a plurality of players to participate in a second play session during a second time period that is subsequent to the first time period.

Disclosed is a method of providing a dart game image, performed by a dart game device. The method includes: receiving second play-related data from a plurality of other devices; determining, based at least in part on the second play-related data, a display attribute for a second object related to the plurality of other devices; and displaying the second object, based on the determined display attribute. A representative figure is FIG. 13.

A calibration method for a camera which monitors a target board is disclosed, comprising steps: using the camera to capture a target image corresponding to the target board; using rotation and translation to align the target image to a reference standard and acquire the corresponding relationship of the target image and the target board; defining a region of interest above the target image; using at least one positioning marker in at least two positions of the target board, whose actual space coordinates are known, and using the camera to acquire at least two image coordinates of the positioning markers in the region of interest; and using the known actual space coordinates and the acquired image coordinates to work out the exact position of the camera. Thereby, the positions of the cameras can be used to correctly determine the positions of darts.

The present invention relates to an electronic dart machine for displaying a point of a corresponding part in an area hit by a dart, using an LED. The present invention provides an electronic dart machine including: a dart target part, which has the shape of a board having multiple divided target areas and includes a sensor means for detecting the location of a target area hit by a dart; an LED display part positioned at a location corresponding to each target area along the periphery of the dart target part; and a controller for controlling an output display of each LED module by preset control logic, recognizing the location of the target area hit by the dart, through the sensor means, and producing a dart hitting result by linking a content of the output display of the LED module with the location of the target area hit by the dart.

In order to achieve the object, disclosed is a dart game apparatus for recording a moving picture of a part during a dart game. The dart game apparatus includes: a camera unit for recording the dart game; a touch unit for sensing that a dart game player is ready for throwing a dart; and a controller for controlling the camera unit, wherein the controller allows the camera unit to start recording at the time when the touch unit senses that the dart game player is ready for throwing the dart. An object of the present invention is to store or transmit only small-capacity data by recording only a part of a dart game or selecting and storing or transmitting only a part of an image of an entire dart game to reduce a burden in storing and transmitting data and remarkably reduce a time for verifying the data.

Disclosed is a method for providing a dart game image, which is performed by a dart game device for participating in a play session assigning a play time constraint to two or more devices according to some embodiments of the present disclosure. The method for providing a dart game image may include determining a valid play time period of the play session based on the play time constraint assigned to the play session, wherein the valid play time period at least partially corresponds to a valid play time period of another device participating in the play session; and displaying information related to the valid play time period.

In order to achieve the object, disclosed is a dart game apparatus for recording a moving picture of a part during a dart game. The dart game apparatus includes: a camera unit for recording the dart game; a touch unit for sensing that a dart game player is ready for throwing a dart; and a controller for controlling the camera unit, wherein the controller allows the camera unit to start recording at the time when the touch unit senses that the dart game player is ready for throwing the dart. An object of the present invention is to store or transmit only small-capacity data by recording only a part of a dart game or selecting and storing or transmitting only a part of an image of an entire dart game to reduce a burden in storing and transmitting data and remarkably reduce a time for verifying the data.

An improved game of darts provides challenging new rules for making dart games more interesting, which provides a way of including the principles of the dice game, LCR, with popular dart games, like Cricket and 301. A special 6-sided dice is needed when playing these new versions of dart games.

The present invention features a dart board comprising a digital target display ring (DTDR) surrounding a target area. The DTDR is operatively connected to a controller with a microprocessor, wherein said microprocessor is configured to (a) receive an input signal from an input device when the input device is actuated, and (b) generate an output signal to the DTDR for the DTDR to display a unique graphic according to pre-programmed commands for the actuated input device.

A game board apparatus includes a pair of game boards, one or more beverage containers supported by the game boards, and a plurality of darts. A method of using the game board apparatus includes throwing darts at the beverage containers in an effort to puncture the beverage containers and consuming the beverages in the beverage containers in the event the beverage containers are punctured.
