Description

The present invention relates to a card processing device used, for example, in live video of a card game distributed via the Internet, a card game system equipped with the same, a card processing method, and a card processing program.

In recent years, as e-Sports has become increasingly popular, various games are being distributed over the Internet. Under such circumstances, live video of card games such as playing cards is also being distributed over the Internet.
However, in card games, the rules are to keep the deck of cards face down while not showing the other players the cards in their hand (face up), making it difficult for online viewers to understand the situation and tactics being played during the game, making it difficult to attract viewers' interest in online live commentary.

For example, Patent Document 1 discloses a table game system that provides an opportunity to bet on higher payout odds without complexity and an opportunity to place additional bets during play by attaching an ID code such as a barcode or a QR code (registered trademark) to a set of playing cards.
Furthermore, Patent Document 2 discloses a game card that is used when extracting a scratch image corresponding to a unique title, and that has an optically readable identification information section on the back side that displays identification information corresponding to the unique title, allowing players to enjoy the inherent fun of a scratch card.

JP 2022-24095 A JP 2021-119991 A

However, the above-mentioned conventional table game systems and game cards have the following problems.
That is, in the table game system disclosed in the above-mentioned Patent Document 1, an ID code such as a barcode or a QR code (registered trademark) is attached to each set of playing cards, thereby identifying the characteristics of each set.

However, with this configuration, it is not possible to identify information about each individual card, such as playing cards, and therefore it is not possible to attract the attention of viewers in live online broadcasts.
Furthermore, in the gaming card disclosed in Patent Document 2, a two-dimensional code, one-dimensional code, etc. is used as the identification information section attached to the back side of the card. Therefore, by attaching a code to the back side of the card, the design is detracted from and there is a possibility that the code may be read by visual inspection.

Furthermore, in order to determine the card information without placing a burden on the player, it is necessary to detect the card itself. Furthermore, card designs are generally rotationally symmetrical about the center of the card, and even if the card is detected, it is difficult to determine the up-down direction of the card from the card design.
As another method, there is a known example in which an RF-ID (Radio Frequency Identifier) tag is embedded in the card and the card information is read using an RF-ID reader attached to a table to use for calculating points and determining the winner. However, embedding an RF-ID makes the card thicker and more difficult to bend, and there are issues with durability against bending.

The objective of the present invention is to provide a card processing device that is capable of identifying information on face cards that are difficult to identify visually and that can be identified by information attached to the cards, as well as a card game system, a card processing method, and a card processing program that include the same.

The card processing device according to the first invention is a card processing device that reads information on gaming cards used during the playing of a card game, and includes an image acquisition unit, an information reading unit, a card type identification unit, and a display control unit. The image acquisition unit acquires image data including the gaming card photographed by an imaging device.

A card processing device 10 according to one embodiment of the present invention and a card game system 20 equipped with the same will be described below with reference to Figs.
In this embodiment, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art.
Furthermore, the applicant provides the accompanying drawings and the following description so that those skilled in the art can fully understand the present invention, and they are not intended to limit the subject matter described in the claims.

(1) Configuration of the Card Game System 20 The card game system 20 according to this embodiment uses gaming cards C (see FIG. 4) containing information that can be read by a predetermined information reading device (such as a camera) to identify the face cards on the front side of the gaming cards C placed face down in card games such as competitive card games and playing card games used in gaming facilities such as casinos, and displays them on a display device or the like.

The gaming cards C include, for example, cards used in competitive card games and playing cards used in gaming facilities such as casinos.
As shown in FIG. 1, a card game system 20 of this embodiment comprises a card processing device 10, an imaging device (camera) 21, and a display device 22.
2, the card processing device 10 is, for example, a PC (Personal Computer) or one of the applications installed on the PC, and reads information attached to the back (second side) Cb of the gaming card C photographed by the imaging device 21 during playing a card game using the gaming card C described above, and identifies the picture card attached to the front (first side) Ca. The detailed configuration of the card processing device 10 will be described later.

As shown in FIG. 1, the imaging device 21 is connected to the card processing device 10 and transmits image data of images captured continuously or intermittently to the card processing device 10. As shown in FIG. 2, the imaging device 21 is attached to a mounting base 21a in order to capture images from above of a gaming table 30 on which a card game is played. This allows the imaging device 21 to capture images including a gaming card C placed in a predetermined position on the gaming table 30.

In this embodiment, as shown in FIG. 3, the gaming table 30 has a gaming area 31 on its upper surface where ten players can play simultaneously, and each player has a card placement area 32 on which a gaming card C is placed.
Therefore, when photographing the gaming table 30 from above, the imaging device 21 photographs an image including the gaming cards C placed in the card placement areas 32 of the gaming areas 31 corresponding to each player.

The display device 22 is connected to the card processing device 10 as shown in Fig. 1, and the display contents are controlled by the display device 22. The display device 22 may be a PC for an administrator who hosts a card game as shown in Fig. 2, or may be a PC owned by a viewer who watches a live game video distributed via the Internet.
Here, the gaming card C used in this embodiment has a picture card attached to the front surface Ca, and a common pattern D1 attached to the back surface (second surface) Cb as shown in Fig. 4. Also, a QR code (information) (registered trademark) C1 is attached at approximately the center of the common pattern D1 on the back surface Cb of the gaming card C as shown in Fig. 4.

The QR code (information) C1 is attached by printing or the like to the back (second surface) side of the gaming card C, and contains information that can be read by an information reading device such as an imaging device 21. Specifically, the QR code C1 is located approximately in the center of the common pattern D1, as shown in FIG. 4. The QR code C1 is also attached to the front (first surface) Ca side, and contains information indicating a correspondence with a different picture card for each gaming card C, making it difficult to visually identify the picture card on the front Ca side.

As shown in Figure 5, the search mark C2 is an approximately square pattern portion located at each of three of the four corners on the back surface Cb side of the approximately rectangular gaming card C, and is mainly used to determine whether or not the gaming card C is present, as well as to detect the position of the QR code C1.
The information of the read QR code C1 of the gaming card C is converted into information of the face card (card value) using the conversion table shown in Fig. 6. For example, when the gaming card C is a playing card, a different QR code C1 is attached to each of the 52 cards x number of sets, and the difference between them is configured so that it cannot be distinguished by the naked eye.

Then, the information of the face card converted using the conversion table shown in FIG. 6 is displayed on the display device 22 or the like as the reading result of the gaming card C held by each player, as shown in FIG.
The read results displayed on the display device 22 may be displayed superimposed on the image of the gaming table 30 for each card placement area 32 of the playing area 31 of each player, as shown in FIG.

(2) Configuration of the card processing device 10 As shown in FIG. 1, the card processing device 10 according to this embodiment includes an image acquisition unit 11, an information reading unit 12, a card type identification unit 13, a reading determination unit 14, an error notification unit 15, a result notification unit 16, a display control unit 17 and a memory unit 18.
The image acquisition unit 11 acquires, from the imaging device 21, images captured continuously or intermittently by the imaging device 21, particularly image data of an image of the top surface of the gaming table 30 including the gaming cards C. The image acquisition unit 11 may acquire image data from the imaging device 21, for example, at predetermined time intervals or continuously.

The information reading unit 12 reads information of the QR code C1 attached to the back surface Cb of the gaming card C from the image data of the gaming card C acquired by the image acquisition unit 11 .
The card type identification unit 13 identifies the type of face card attached to the front Ca side of the gaming card C based on the information included in the QR code C1 read by the information reading unit 12. In this embodiment, the card type identification unit 13 identifies the face card (card value) of the gaming card C using a conversion table (see FIG. 6 ) in which the read information is associated with a correspondence between the face card and the card value.

The reading determination unit 14 determines whether or not the information on the back Cb side of the gaming card C was read correctly. Specifically, if the reading determination unit 14 cannot detect, for example, three search marks C2 arranged at three corners on the back Cb side of the gaming card C, it determines that the gaming card C is not in a state in which the QR code C1 can be read correctly, and determines this as a reading error.

The error notification unit 15 notifies a read error when the reading determination unit 14 determines that the information could not be read normally. Specifically, the error notification unit 15 transmits a message to the administrator's PC, etc., when a read error occurs, prompting the administrator to set the gaming card C in the correct position.
The result notifying unit 16 notifies, for example, an administrator hosting the card game, of the type of the face card affixed to the face Ca side of the gaming card C identified by the card type identifying unit 13.

The display control unit 17 controls the display device 22 to display the type of face card attached to the front side Ca of the gaming card C identified by the card type identification unit 13. Specifically, the display control unit 17 displays information about the face card on the front side Ca of the gaming card C identified by the card type identification unit 13, superimposed on an image of the gaming table 30, as shown in FIG. 8, for example.

Thus, for example, when a video of a card game is distributed via the Internet, a viewer can enjoy the card game in progress with interest while recognizing the information of the face cards of each game card C in a face-down state superimposed on the image of the game table 30.
The memory unit 18 stores a conversion table (see FIG. 6) that is referenced after the information reading unit 12 reads the QR code C1 and indicates the relationship between the information of the QR code C1 read by the information reading unit 12 and the information (face card) on the front Ca side of the gaming card C. The memory unit 18 further stores a table (see FIG. 7) that indicates the reading results for each player whose QR code C1 was read during the card game.

<Card processing method>
The card processing device 10 of this embodiment, with the above-mentioned configuration, executes a card processing method in accordance with the flowcharts shown in FIGS.
That is, as shown in FIG. 9, in step S11, the image acquisition unit 11 acquires, from the imaging device 21, image data of an image including a gaming card C on the gaming table 30 photographed by the imaging device 21.

Next, in step S12, the information reading unit 12 reads the information of the QR code C1 attached to the back surface Cb of the gaming card C, which is included in the image data acquired in step S11.
The information reading process in step S12 will be described in detail later with reference to the flowchart of FIG.

Next, in step S13, the result notification unit 16 notifies the PC or the like owned by the administrator of the result of the reading in step S12, and the display control unit 17 causes the display device 22 to display the result of the reading.
Next, in step S14, it is determined whether or not the reading is completed. If it is completed, the process is terminated, and if it is not completed, the process is repeated from step S11.

Next, the information reading process in step S12 will be described in detail with reference to the flowchart of FIG.
The information reading process shown in FIG. 10 is repeated until the information on the game cards C of all the ten players shown in FIG. 8 is read.
In step S21, the information reading unit 12 uses the image data acquired by the image acquisition unit 11 to search for the search marks C2 arranged at the three corners of the back surface Cb of the gaming card C. More specifically, the information reading unit 12 detects the back surface Cb of the gaming card C placed in a predetermined card placement area 32 on the top surface of the gaming table 30 using the image data acquired by the image acquisition unit 11 from the imaging device 21, and searches for the search marks C2.

Next, in step S22, the information reading unit 12 judges whether or not the search mark C2 has been found. If the search mark C2 has not been found, the process proceeds to step S29, and if the search mark C2 has been found, the process proceeds to step S23.
Next, in step S23, since it is determined that the search mark C2 was found in step S22, the information reading unit 12 determines whether or not a gaming card C is present based on the number of search marks C2 found and the positional relationship of the search marks C2 (the ratio of the sides of the gaming card C, the angle, etc.).

Next, in step S24, based on the result of the card presence/absence determination in step S23, it is determined whether or not there is a gaming card C included in the image data on the top surface (card placement area 32) of the gaming table 30. If it is determined that there is a gaming card C, the process proceeds to step S25, and if it is determined that there is no gaming card C, the process proceeds to step S29.
Next, in step S25, since it was determined in step S24 that a gaming card C is present in the card placement area 32, the information reading unit 12 identifies the position of the QR code C1 based on the position of the search mark C2 searched for in step S21.

Next, in step S26, the information reading unit 12 reads the QR code C1 whose position was identified in step S25.
Next, in step S27, the reading determination unit 14 determines whether or not the reading of the code in step S26 was successful. If the reading of the code was successful, the process proceeds to step S28, and if not, the process proceeds to step S29.

Next, in step S28, information on the face card (card value) of the gaming card C that was successfully read in step S27 is stored in the memory unit 18 as a result.
On the other hand, in step S29, since it has been determined in steps S22, S24 and S27 that there is no search mark C2, there is no gaming card C and the code reading has failed, there is no reading result and the process is terminated.
In this embodiment, the above-mentioned processes from step S21 to step S29 are repeated for all players currently playing.
