JP 2005-143787 A

  By the way, in general, in a card game or the like, if the opponent's hands are known to the opponent, it will be disadvantageous for fighting. For this reason, it is often the case that a dedicated monitor is provided for each player, or that each player brings a separate game device and connects them via a network to play together. However, if an attempt is made to assign a monitor or a game device separately for each player, there is a problem that the entire system becomes expensive or the system configuration becomes complicated. In addition, it may be difficult to secure a space for allocating a monitor and a game device separately for each player.

  The present invention solves such a problem. In a game in which each of a plurality of players is inconvenient when their opponent's game content is known to the opponent, only one monitor is provided without providing a dedicated monitor for each player. It is an object of the present invention to provide a game device, a game processing method, and a program that are suitable for playing a game together.

  In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.

A game device according to a first aspect of the present invention includes a plurality of shutter glasses, an image display unit, and a control unit.
Each of the plurality of shutter glasses can switch between transmission and non-transmission of light.
The image display unit switches images associated with each of the plurality of shutter glasses in a time division manner and displays them on one screen.
For each of the plurality of shutter glasses, the control unit transmits light to the shutter glasses while the image associated with the shutter glasses is displayed on the screen, and the image associated with the shutter glasses is displayed on the screen. While not displayed on the screen, the shutter glasses are made impermeable to light.

  In the game apparatus of the present invention, a plurality of players wear shutter glasses, and all of the players play a game while watching one screen through the shutter glasses. A game is a game in a virtual space, such as playing cards, mahjong, etc., in which inconvenience occurs when each of a plurality of players knows their game contents. In playing cards and mahjong, if your card or trap is known to your opponent, there is a high probability that it will be a disadvantage. Ideally, having a monitor that only you can see for each player reduces the risk that your opponent will see information you don't want others to know. However, preparing monitors for the number of players is cumbersome and expensive. Also, there is not always a space where many monitors can be installed. Therefore, in the present invention, while everyone is sharing one monitor, the other party's game content is not known to the other party.

  That is, on the screen, images associated with the respective shutter glasses are alternately displayed in a time division manner. The image associated with the shutter glasses is an image representing a card held by the player in, for example, a playing card. On the screen, an image representing the card held by the first player, an image representing the card held by the second player, and an image representing the card held by the third player are alternately displayed. When N players (N is an integer of 2 or more) participate in the game, an image representing the cards held by the Nth player is displayed, and then an image representing the cards held by the first player is displayed. The That is, the image associated with the shutter glasses displayed on the screen is switched cyclically.

  Then, while an image associated with certain shutter glasses is displayed on the monitor, light is transmitted through the shutter glasses. On the other hand, while an image associated with a certain shutter glasses is not displayed on the monitor, the shutter glasses are made opaque. That is, the player wearing the shutter glasses can only see an image associated with the shutter glasses (that is, an image representing a card on hand), and an image that is not associated with the shutter glasses (that is, You cannot see the image that represents someone else's card.

  Therefore, each player can see an image associated with the shutter glasses worn by the player, and cannot view an image associated with the shutter glasses worn by another person. According to the present invention, it is possible to play a game together with only one monitor without the opponent knowing his / her game content.

  The image display unit may display an image associated with each of the plurality of shutter glasses at a predetermined position on the screen and different from each other.

  In other words, the image is displayed at a different position for each player, making it easier to see the screen. For example, in a game in which a plurality of players play against each other, it is possible to improve a sense of presence that a plurality of players are playing the game at the same time.

  The image display unit is configured to display a predetermined mask image at a position where the image associated with the one shutter glasses is displayed while the image associated with the one shutter glasses is not displayed on the screen. May be displayed.

  That is, when the display position of an image representing a card held by each player is fixed, while the image representing a card held by a player is not displayed, the card held by that player is displayed at that display position. An image that is difficult to understand is displayed. If the player removes the shutter glasses, the player may be able to see an image representing another person's card. However, according to the present invention, since the mask image that hides the card held by another person is displayed, it is possible to prevent an illegal act of removing the shutter glasses and viewing the screen.

  The image display unit generates a mask image by combining at least two images among all the images associated with each of the plurality of shutter glasses, and the generated mask image is used as the one shutter glasses. You may display in the position which displays the matched image.

  According to the present invention, not only can the opponent know his / her game content, but the user can not only play the game together on a single monitor, but also if the player tries to see another person's image, the mask image Since the image makes it difficult to grasp the contents, it is more difficult to perform an illegal act such as removing the shutter glasses and viewing the screen.

In the game device, a plurality of players may execute a game using a plurality of cards having predetermined different patterns in the virtual space.
Then, the image display unit generates a mask image by combining symbols of at least two or more of the plurality of cards, and displays the generated mask image corresponding to the one shutter glasses. You may display in the position to do.

  For example, in a game device, a game using cards such as playing cards and flower cards is executed. An image obtained by synthesizing various patterns becomes a mask image. According to the present invention, not only can the opponent know his / her game content, but the user can not only play the game together on a single monitor, but also if the player tries to see another person's image, the mask image Since the image makes it difficult to grasp the contents, it is more difficult to perform an illegal act such as removing the shutter glasses and viewing the screen.

  The image display unit may use a moving image as the mask image.

  That is, it is easier to camouflage the contents by using a moving image than by using a still image as a mask image. According to the present invention, it is possible to increase an effect that an illegal act of removing the shutter glasses and viewing the screen becomes more difficult.

  The image display unit is configured to display the image associated with the one shutter glasses at a position where the image associated with the one shutter glasses is displayed while the image associated with the shutter glasses is not displayed on the screen. A mask image generated in the same color as the image associated with the glasses may be displayed.

  That is, if an image associated with a certain shutter glasses is a predetermined color (for example, “red”), a mask image for camouflaging the image associated with the shutter glasses is also created in the same color. Therefore, according to the present invention, it is possible to increase the effect that it is more difficult to perform an illegal act of removing the shutter glasses and viewing the screen.

A game processing method according to another aspect of the present invention is a game executed by a game device having a plurality of shutter glasses capable of switching between transmission and non-transmission of light, an image display unit, and a control unit. A processing method comprising an image display step and a control step.
In the image display step, the image display unit switches the images associated with each of the plurality of shutter glasses in a time division manner and displays them on one screen.
In the control step, for each of the plurality of shutter glasses, the control unit transmits light to the shutter glasses while the image associated with the shutter glasses is displayed on the screen, and associates the shutter glasses with the shutter glasses. While the displayed image is not displayed on the screen, the shutter glasses are made impermeable to light.

  According to the present invention, it is possible to play a game together with only one monitor without the opponent knowing his / her game content.

A program according to another aspect of the present invention causes a computer having a plurality of shutter glasses capable of switching between transmission and non-transmission of light to function as an image display unit and a control unit.
The image display unit switches images associated with each of the plurality of shutter glasses in a time division manner and displays them on one screen.
For each of the plurality of shutter glasses, the control unit transmits light to the shutter glasses while the image associated with the shutter glasses is displayed on the screen, and the image associated with the shutter glasses is displayed on the screen. While not displayed on the screen, the shutter glasses are made impermeable to light.

According to the present invention, it is possible to cause a computer to function as a game device that operates as described above.
The program of the present invention can be recorded on a computer-readable information storage medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.
The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information storage medium can be distributed and sold independently from the computer.

  According to the present invention, it is possible to play a game together with only one monitor without providing a dedicated monitor for each player in a game that causes inconvenience when each of a plurality of players knows the game content of the other player. Therefore, it is possible to provide a game device, a game processing method, and a program that are suitable for achieving the above.

  The CPU 101 controls the overall operation of the information processing apparatus 100 and is connected to each component to exchange control signals and data. Further, the CPU 101 uses arithmetic operations such as addition / subtraction / multiplication / division, logical sum, logical product, etc. using an ALU (Arithmetic Logic Unit) (not shown) for a storage area called a register (not shown) that can be accessed at high speed. , Logic operations such as logical negation, bit operations such as bit sum, bit product, bit inversion, bit shift, and bit rotation can be performed. In addition, the CPU 101 itself is configured so that saturation operations such as addition / subtraction / multiplication / division for multimedia processing, vector operations such as trigonometric functions, etc. can be performed at a high speed, and those provided with a coprocessor. There is.

  The ROM 102 records an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, the program recorded on the DVD-ROM is read out to the RAM 103 and execution by the CPU 101 is started. The The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for game progress and chat communication. Further, the CPU 101 provides a variable area in the RAM 103 and performs an operation by directly operating the ALU on the value stored in the variable, or temporarily stores the value stored in the RAM 103 in the register.

  The controller 105 connected via the interface 104 receives an operation input performed by the player when executing a game such as a dance game or a soccer game. A plurality of controllers 105 may be connected to the interface 104.

  The external memory 106 detachably connected via the interface 104 stores data indicating game play status (past results, etc.), data indicating game progress, and log of game chat communication using the network ( Data) is stored in a rewritable manner. The player can appropriately record these data in the external memory 106 by performing an operation input via the controller 105.

  A DVD-ROM mounted on the DVD-ROM drive 107 stores a program for realizing the game and image data and sound data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 107 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  The image processing unit 108 processes the data read from the DVD-ROM by the CPU 101 or an image arithmetic processor (not shown) included in the image processing unit 108, and then processes the processed data on a frame memory ( (Not shown). The image information recorded in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor (not shown) connected to the image processing unit 108. Thereby, various image displays are possible.

  The image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed.

  The shutter glasses 120 switch between transmission and non-transmission of light in a time division manner. The shutter glasses 120 are connected via the interface 104, and one shutter glasses 120 is assigned to one player. Each player wears the assigned shutter glasses 120 and looks at one monitor shared by each player. The monitor associates with the first image associated with the first shutter glasses, the second image associated with the second shutter glasses, and the Nth shutter glasses (N is an integer of 2 or more). The displayed Nth image is switched in a time division manner and displayed.

  While the first image is displayed on the monitor, the first shutter glasses transmit light and the other shutter glasses do not transmit light. Similarly, while the Nth image is displayed on the monitor, the Nth shutter glasses transmit light, and the other shutter glasses do not transmit light. That is, each player wearing the shutter glasses 120 can see only the image associated with the worn shutter glasses 120 through the shutter glasses 120, and cannot view the images associated with the other shutter glasses 120. Can not.

  Next, a functional configuration and the like of the game device 200 of the present embodiment realized by the information processing device 100 having the above configuration will be described.

  FIG. 2 is a diagram illustrating a functional configuration of the game apparatus 200. The game apparatus 200 includes a plurality of the above-described shutter glasses 120 (described as 120A, 120B, 120N, etc. in the drawing), an image display unit 202, and a control unit 203.

  The image display unit 202 switches the images associated with each of the plurality of shutter glasses 120 in a time division manner and displays the images on one screen. The CPU 101 and the image processing unit 108 cooperate to function as the image display unit 202.

  The image associated with each shutter glasses 120 is an image representing a card held by the player in a card game in a virtual space where a plurality of players participate, for example. However, the content of the game or image is not limited by the present invention.

  3 to 6 are display examples of images associated with each of the shutter glasses 120 displayed on the monitor at a certain time in a poker game in which four players participate. 3 is associated with the first shutter glasses worn by the first player, and the image 400 shown in FIG. 4 is associated with the second shutter glasses worn by the second player. An image 500 shown in FIG. 5 is associated with the third shutter glasses worn by the third player, and an image 600 shown in FIG. 6 is associated with the fourth shutter glasses worn by the fourth player.

  In the present embodiment, the CPU 101 determines that the display positions of the images associated with the respective shutter glasses are different from each other. However, the CPU 101 may make the display positions of the images associated with the respective shutter glasses the same.

  For each of the plurality of shutter glasses 120, the control unit 203 transmits light to the shutter glasses 120 while an image associated with the shutter glasses 120 is displayed on the screen. In addition, for each of the plurality of shutter glasses 120, the control unit 203 causes the shutter glasses 120 to transmit light while an image associated with the shutter glasses 120 is not displayed on the screen. The CPU 101 and the shutter glasses 120 work together to function as the control unit 203.

Here, the processing performed by the control unit 203 will be described in detail with reference to FIG.
FIG. 7 is a timing chart showing the correspondence between the image displayed on the monitor and the transmission / non-transmission of each shutter glasses 120. The CPU 101 switches the image to be displayed on the monitor to the first image 300, the second image 400, the third image 500, and the fourth image 600, and after displaying the fourth image, the first image again. The image 300 is displayed. That is, the image displayed on the monitor is cyclically switched, such as the first image 300, the second image 400, the third image 500, the fourth image 600, and the first image 300. The CPU 101 switches between transmission (ON) / non-transmission (OFF) of the first, second, third, and fourth shutter glasses at the timing of switching the image displayed on the monitor.

  The CPU 101 displays the first image 300 associated with the first shutter glasses on the monitor at a certain time T1, transmits light through the first shutter glasses, and performs the second, third, and fourth. The shutter glasses are made opaque. That is, only the first player can see the first image 300 at time T1.

  In addition, the CPU 101 displays the second image 400 associated with the second shutter glasses on the monitor at time T2 after the time T1, and transmits light through the second shutter glasses, The third and fourth shutter glasses are made opaque. That is, only the second player can see the second image 400 at time T2.

  In addition, the CPU 101 displays the third image 500 associated with the third shutter glasses on the monitor at time T3 after the time T2, and transmits light through the third shutter glasses, The second and fourth shutter glasses are made opaque. That is, only the third player can see the third image 500 at time T3.

  In addition, the CPU 101 displays the fourth image 600 associated with the fourth shutter glasses on the monitor at time T4 after the time T3, and transmits light through the fourth shutter glasses, The second and third shutter glasses are made opaque. That is, only the fourth player can see the fourth image 600 at time T4.

  The length of time from time T1 to time T2, the length of time from time T2 to time T3, and the length of time from time T3 to time T4 are equally spaced.

  While the first image 300 is displayed, the CPU 101 displays a predetermined mask image in an overlapping manner in the area where the second image 400, the third image 500, and the fourth image 600 are displayed. Shall. For example, in the card game, while the card held by the first player (first image 300) is displayed, the card held by the second player (second image 400) and the hand held by the third player In the portion where the card (third image 500) and the card held by the fourth player (fourth image 600) are displayed, an image with the card turned upside down is displayed. The same applies to the display of the second image 400, the display of the third image 500, and the display of the fourth image 600.

  Next, the game process executed by each unit of the present embodiment will be described with reference to the flowchart of FIG. In this embodiment, N players (N is an integer equal to or greater than 2) participate in the game, and each player wears pre-assigned shutter glasses 120 and all of them are watching a screen displayed on one monitor. A game shall be played. The parameters x and i are both integers of 1 or more.

  For example, when N = 4, the first image is associated with the first shutter glasses, the second image is associated with the second shutter glasses, and the third image is associated with the third shutter glasses. The fourth image is associated with the fourth shutter glasses. The first player wears first shutter glasses, the second player wears second shutter glasses, the third player wears third shutter glasses, and the fourth player Wear shutter glasses.

  The CPU 101 sets parameters x and i to 1 and initializes them (step S801).

  The CPU 101 displays the xth image on the monitor (step S802). For example, as shown in FIGS. 3 to 6, when the first image 300, the second image 400, the third image 500, and the fourth image 600 are displayed alternately, the first image 300 The first image, the second image 400 is the second image, the third image 500 is the third image, and the fourth image 600 is the fourth image.

  The CPU 101 performs control so that light is transmitted through the xth shutter glasses and light is not transmitted through other shutter glasses (step S803). That is, only the player wearing the xth shutter glasses can see the xth image.

  The CPU 101 determines whether or not to end the game (step S804). For example, in a poker game, when only one player is left and all other players are folded (down), the CPU 101 determines that the game is to be ended.

  When it is determined that the game is to be ended (step S804; YES), the CPU 101 ends the game process. On the other hand, if it is determined that the game is not to be ended (step S804; NO), the CPU 101 determines whether it is time to switch the image displayed on the monitor (step S805).

  For example, when the timing at which the vertical synchronization interrupt (VSYNC) occurs is set as the timing for switching images, the CPU 101 determines that the image to be displayed is replaced when VSYNC occurs.

  When it is determined that it is not the image switching timing (step S805; NO), the CPU 101 returns to the process of step S804. On the other hand, if it is determined that it is the image switching timing (step S805; YES), the CPU 101 increments the parameter i and calculates the parameter x using [Equation 1] (step S806).

    x = i mod N (1)

  Here, the operator “mod” represents that the remainder is obtained from the division result. That is, parameter x is the remainder when parameter i is divided by N (number of players).

  Then, the CPU 101 returns to the process of step S802 and repeats the processes of steps S802 to S806 until the game ends.

  According to the present embodiment, for example, in a game that is inconvenient if each of a plurality of players knows the contents of the game to the other party, such as a card game, one player can be provided without providing a plurality of monitors dedicated to each player. You can play games together in the same place with just a monitor. For example, in a mahjong game, the player can play the game while sharing one monitor without being seen by the opponent.

  While the CPU 101 does not display an image associated with a certain shutter glasses 120, the CPU 101 arranges a mask image in a region where an image associated with the shutter glasses 120 is displayed. In this embodiment, the CPU 101 uses a predetermined image representing the back side of the card as the mask image, but there are various variations in the mask image.

  The CPU 101 may fix the color of the image associated with the shutter glasses 120 for each image, and generate a mask image using the fixed color.

  For example, as illustrated in FIG. 9, when the image 910 associated with the first shutter glasses is created with a predetermined first color (for example, “red”), the CPU 101 determines that the first shutter glasses are The color of the image (mask image) 911 that masks the image 910 associated with is also set to the first color. Similarly, when the image 920 associated with the second shutter glasses is created in a predetermined second color (for example, “blue”), the CPU 101 displays the image associated with the second shutter glasses. The color of the image (mask image) 921 masking 920 is also set to the second color.

  Then, the CPU 101 displays the images 910, 911, 920, and 921 on the monitor at the timings shown in the timing charts of FIGS. More specifically, the CPU 101 displays the images 910 and 911 associated with the first shutter glasses at predetermined positions on the monitor, and displays the images 920 and 921 associated with the second shutter glasses on the monitor. The display target is sequentially switched and displayed at a predetermined position (however, a position different from the images 910 and 911).

  That is, as shown in FIG. 10A, the CPU 101 alternately displays the image 910 and the image 911 at the same time interval ΔT at the position associated with the first shutter glasses. Further, as shown in FIG. 10B, the CPU 101 alternately displays the image 920 and the image 921 at the same time interval at the position associated with the second shutter glasses.

11A to 11D are display examples on the monitor.
At time TA, as shown in FIG. 11A, the CPU 101 displays an image 910 associated with the first shutter glasses at a position 1101, and corresponds to the second shutter glasses at a position 1102. The attached mask image 921 is displayed.

  Here, if the second player who should use the second shutter glasses removes the second shutter glasses, the second player can see the images 910 and the mask images 911 alternately. Become. For example, when the time interval is set to VSYNC equivalent (1/60 seconds), the image 910 and the mask image 911 should appear to be interchanged instantaneously, but the image 910 and the mask image 911 are created using the same color. For this reason, the image 910 appears to be melted into the mask image 911, and it looks substantially as shown in FIG. 11B for a human being, making it very difficult to discriminate the image 910. Therefore, by using the same color for the image 910 and the mask image 911, even if the player tries to cheat the person who removes the shutter glasses and looks at the monitor, the cheating becomes difficult.

  At time TB, the CPU 101 switches the image to be displayed on the monitor as shown in FIG. That is, the CPU 101 displays a mask image 911 associated with the first shutter glasses at a position 1101 and an image 920 associated with the second shutter glasses at a position 1102.

  Here, if the first player who should use the first shutter glasses removes the first shutter glasses, the image 920 and the mask image 921 are seen alternately by the first player. Become. For example, when the time interval is set to be equivalent to VSYNC, the image 920 and the mask image 921 should appear to be interchanged instantaneously. However, since the image 920 and the mask image 921 are created using the same color, the image 920 Will appear to be melted into the mask image 921, which is practically as shown in FIG. 11 (d) for a human being and makes it very difficult to distinguish the image 920. Therefore, by using the same color for the image 920 and the mask image 921, even if the player tries to cheat the person who removes the shutter glasses and looks at the monitor, the cheating becomes difficult.

  Further, the CPU 101 generates a mask image by synthesizing all the patterns that may be arranged, and arranges the generated mask image at a position where an image associated with the shutter glasses 120 is displayed. Good. For example, in a playing card, the CPU 101 may generate a single mask image by combining numbers 1 to 10 and all symbols J (jack), Q (queen), and K (king). Alternatively, the CPU 101 may generate one mask image by combining at least two of all symbols.

  For example, FIG. 12 is an example of a mask image obtained by combining a plurality of images associated with shutter glasses. Here, in order to simplify the description, there are only two players, the image associated with the first shutter glasses is the image 910 shown in FIG. 9, and the image associated with the second shutter glasses. Is an image 920 shown in FIG. The CPU 101 combines the image 910 associated with the first shutter glasses and the image 920 associated with the second shutter glasses to generate one mask image 1210. While the CPU 101 does not display the image associated with the first shutter glasses, the CPU 101 displays the generated mask image 1210 at the position where the image associated with the first shutter glasses is to be arranged. Similarly, the CPU 101 displays the generated mask image 1210 at a position where the image associated with the second shutter glasses is to be placed while not displaying the image associated with the second shutter glasses. Therefore, it becomes difficult for a player who has removed the shutter glasses to know which image portion is associated with which shutter glasses, that is, which image portion is who's image, and fraud is difficult.

  The CPU 101 combines all the images associated with each shutter glasses 120 to generate a mask image, and arranges the generated mask image at a position where the image associated with the shutter glasses 120 is displayed. Also good. Alternatively, the CPU 101 may arbitrarily select two or more images among all the images associated with each shutter glasses 120 and synthesize the selected images to generate a mask image.

  Further, the CPU 101 may use a moving image as a mask image instead of a still image. The content of the moving image is arbitrary. By making the mask image a moving image, the effect of preventing an image associated with the shutter glasses from being illegally seen by others is enhanced.

  By devising the mask image as described above, even if the player removes the shutter glasses and sees the other person's image, the image is masked so that it is difficult to see the other person's game content, which makes it difficult to cheat the game. be able to.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible. Moreover, it is also possible to freely combine the constituent elements of the above-described embodiments.

  A program for operating a computer as all or part of the above-described game apparatus 200 is stored in a computer-readable recording medium such as a memory card, CD-ROM, DVD, or MO (Magneto Optical disk) and distributed. This may be installed in another computer and operated as the above-described means, or the above-described steps may be executed.

  Furthermore, the program may be stored in a disk device or the like included in a server device on the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.

  As described above, according to the present invention, in a game that causes inconvenience when each of a plurality of players knows his / her game content to the other party, only one monitor can be used together without providing a dedicated monitor for each player. It is possible to provide a game device, a game processing method, and a program suitable for enabling a game to be played.
