The present invention relates to a card game apparatus, a card game control method, a card data reading apparatus, a recording medium, a program, and a card, which are configured such that a predetermined video game is provided, contents of which are in accordance with a set of data of cards placed on a play field, by automatically reading card data stored on the back of the card, when the card is placed on the play field.
Some games that use cards determine win or lose according to a predetermined rule that defines combinations of different cards, for example, 52 cards in the card game where each player collects and arranges the cards in hand of each player.
Further, among sport fans of such as soccer and baseball, collection and exchange of cards that bear popular players' photographs, the cards being called “trading cards”, are prevailing.
Various methods of enjoying a game, like card games, according to a predetermined rule using such trading cards are proposed. For example, a proposal has been made by a Japanese provisional-patent-publication No.2000-288155. In this kind of card game, each of players submits a card of a character printed on the back of the card, and compares magnitude of various capacities of the character (a level value assigned to every character) such that an owner of the card that bears the largest level value wins.
However, in such a card game, for example, there is a problem that rules require complicated combinations of the cards, causing it difficult to learn the game easily.
As a game apparatus that alleviates such a dissatisfaction of a player, a proposal has been made, for example, by a Japanese provisional-patent-publication No.2000-157744. There, the proposed game apparatus accepts a cassette to which game data is recorded, portable game machines owned by game players are connected by a cable, a card game is provided more easily, by viewing card images displayed on a screen. In this case, win or lose is decided also by character information stored in the cassette that is installed in the portable game machine. In this manner, a game player can enjoy a game by beating a character of the cassette of the counter-player, collecting cassettes of a stronger character.
However, when a game is performed by looking at virtual card screen displayed on the game machine as mentioned above, pleasure of collecting real trading cards cannot be experienced.
Further, with the card game apparatus that generates a game image by reading card data printed on the card, there is a case that card data may be unable to be read due to aging of the card and the like, and a game cannot be started, staying in a standby state and causing delays of the game start.
Further, in such a card game apparatus, it is necessary to entertain a gallery, including an audience and people waiting for game playing, who desire to know how the game is progressing.
Further, in a card game apparatus that allows participation through using the card bearing the card data printed, only the cards that are legitimately purchased can be used. It is necessary to check if a would-be-player owns a legitimate card. Since a coin is not returned even when the would-be-player cannot participate in a game because the card is not presented or the card is not legitimate (an imitation card) after the coin is inserted. In this manner, there is a possibility of a trouble occurring.
Further, it is necessary that the card game apparatus detects not only an ID code for recognizing a card but also a position and direction (angle) of the card. For this reason, if the ID code, the position and the direction (angle) are to be simultaneously analyzed from an image data obtained by an image sensor, for example, a large number of parameters have to be processed in computation, requiring a considerable period of time.
Further, in order to process the computation at a high speed, an effective method is to screen necessary data and to eliminate unnecessary data through processing the data one by one. However, when a conventional 2-dimensional bar code is used as data pattern for recognizing the card, the bar code has to be read in a direction orthogonal to the bars, requiring a detection of the card angle, which increases the number of the parameters to be simultaneously processed, causing a delay in starting a game.
The present invention aims at offering a card game apparatus, a card data reading apparatus, a card game control method, a recording medium, a program, and a card, which solve the above-mentioned problems.
More specifically, the objective of the present invention is offering the card game apparatus, the card data reading apparatus, the card game control method, the recording medium, the program, which are capable of reading the information stored in two or more cards placed on the play field, deciding win or lose of a game by a simulation of a match according to the combination the cards, and providing a smooth progress of the game according to the combination of the two or more cards, and the card adequate for collection.

Further, the card data reading means of the present invention includes a luminous source that irradiates invisible light to the back of the card, an image sensor that receives the invisible light reflected from the back of the card and generates image data, a data recognition means that discriminates the card data from the image data obtained by the image sensor. In this manner, the characteristics (for example, a sport player's ability) recorded in the cards placed on the play field are obtained as image data, without awareness of the game player, shortening time required by reading of the data pattern.
Further, according to the present invention, a marker is prepared in the four corners of the play field for detecting distortion of an image. An amount of displacement of the marker prepared in the four corners of the play field is obtained from the image data obtained by the image sensor. Based on the displacement amount, reading errors of the card data is compensated. In this manner, the data pattern that represents the characteristics (for example, a sport player's ability) recorded on the cards placed on the play field is accurately detected.
Further, since according to the present invention, a reflective board is provided in a predetermined angle to the back surface of the card such that the light reflected from the back of the card is directed to the image sensor, the card data reading means is realized compactly.

In this manner the game can be started based on the data of the card read from the memory card owned by the game player, and a would-be-player without a memory card is prevented from participating in the game.
Further, according to the present invention, since the memory card owned by the game player stores at least the kinds of the cards, and the skill and the past game result of a player corresponding to the card, data required for a game is obtained by reading the information stored in the memory card, including a qualification for the game player participating in a game.
Further, according to the present invention, a coded pattern recorded on the card is read by an optical reading means using infrared rays. By applying ink that transmits the infrared rays to the surface of the coded pattern, the coded pattern can be protected from being viewed, forged and modified.
Further, according to the present invention, a position detection means is provided, which detects the position of a position detection circle by detecting inner circumference outline data formed by the inner circumference of the position detection circle and the inside of the position detection circle, and outer circumference outline data formed by the outer circumference of the position detection circle and the outside of the position detection circle, such that an accurate card position (coordinates) is obtained regardless of a direction (angle) of the card.
Further, according to the present invention, since the position detection means generates the inner circumference outline data and the outer circumference outline data from a density difference between the outline and the circumference of the position detection circle, an accurate card position (coordinates) is detected.
Further, the present invention attains the objective by providing the play field on which a selection of cards that store unique data are placed, and the card data reading means configured to read the data of the cards placed on the play field, such that a plurality of the cards can be read simultaneously, shortening the reading time.
Further, the present invention provides a player selection mode wherein players that form a team are selected from the plurality of player cards, a player exercise mode wherein selected players exercise, a game mode wherein the image of the game is generated according to parameters of each player and the team, as updated by an exercise program, and a message selection mode wherein a message is selected from a plurality of messages, the message being displayed before, during and after the game. These modes are performed such that the selected message is reflected to the game, the selected players can be trained to raise the level of the team, and results of the exercise can be determined through the game.
Further, the present invention enables a game player to carry out a simulation of the game of a team play with game images displayed, according to players' parameters and team parameters, which are stored in the plurality of the cards placed on the play field, by providing a computer with a program for executing a step 1 wherein players who form a team are selected from the plurality of the player cards, a step 2 wherein each player selected in the step 1 exercise, a step 3 wherein the image of the game is generated according to each player's parameters and team parameters that are updated by the step 2, and a step 4 wherein guidance is given to each player after the game.
Further, the present invention provides a first step wherein the inner circumference outline data formed by the inner circumference of the position detection circle and the inside of the position detection circle, which were recorded on the card, is generated, a second step wherein the outer circumference outline data formed by the outer circumference edge of the position detection circle and the outside of the position detection circle is generated, and a third step wherein the position of the position detection circle is detected by detecting the inner circumference outline data and the outer circumference outline data, and the steps are performed such that the card position (coordinates) is accurately detected.
Further, the present invention provides a first step wherein the position of the position detection circle recorded on the card is detected, a second step wherein an angle detection pattern formed in the outer circumference of the position detection circle is detected, a third step wherein a pattern recorded inside the position detection circle is detected, and a fourth step wherein a pattern recorded on the outside of the position detection circle is detected. The steps are configured such that the card position (coordinates) and card data are accurately detected at a high speed.
Further, the present invention provides a first step wherein information stored in the memory card inserted in a memory card insertion unit is read, a second step wherein a coin insertion is accepted after reading the information stored in the memory card, and a third step wherein a card game is started after receiving the coin inserted. By performing the steps, a game can be started based on the data of the card read in the memory card that a game player owns, and a would-be game player who does not own a memory card can be prevented from participating in a game.
Further, according to the present invention, a unique character according to contents of the game is printed on a front surface of the card, and the card data for recognizing properties of the unique character is recorded on the front or back surface. In this manner, the card that bears patterns corresponding to various games and characters (e.g., sport players) serves collection purposes, while providing data such as properties of the characters (e.g., ability of the sport players) for playing the card game.
Further, since the present invention provides the coded pattern that curves in the direction of the circumference as the stored card data, the coded pattern can be read irrespective of the direction (angle) of the card.
Further, the data pattern is printed in ink that absorbs invisible light according to the present invention such that the signal according to the properties of the characters printed on the surface can be read when the invisible light is irradiated. In this manner, while the data patter of the card can be read correctly, the inside of a case can be made dark such that the card data reading means may not be visible from the upper part of the play field.
Further, according to the present invention, since two or more different patterns having different radii are formed in the shape of concentric circles, a pattern for position detection and an information pattern can be separately stored, and the time required of reading control can be shortened.
Further, according to the present invention, since the coded pattern is formed such that an optical reading means using infrared rays can read, the surface of the coded pattern can be printed with an infrared transmitting paint, such that the coded pattern is invisible, hiding the information contained in the card.
Further, according to the present invention, as for the circular pattern of the coded pattern, which has the largest radius, being greater than the dimension of the shorter edge of the card that is rectangular, only parts of the circular pattern are printed, i.e., only arcs are printed. In this manner, the whole surface area of the card is effectively utilized.
Further, since the coded pattern has the position detection circle for detecting the card position, the inside data formed inside the position detection circle, and the outside data formed in the outside of the position detection circle according to the present invention, the coded pattern for the card position and the coded pattern showing data unique to the card can be stored, increasing the amount of information, and enabling a high-speed process.
Further, according to the present invention, since the angle detection pattern for detecting the angle of the card is arranged at an uneven interval on the outer circumference of the position detection circle, the angle detection pattern is detected, and the direction (angle) of the card is correctly determined, after the card position detection.
Further, according to the present invention, since the coded pattern is formed on both sides of the card, the coded pattern can be read even if the card is placed in reverse.
Further, according to the present invention, since different coded patterns can be recorded on each side of the card, different data can be provided depending on which side of the card is faced down.
Further, according to the present invention, since letters and an image according to the information contents of the coded pattern are printed over the coded pattern, hiding the coded pattern, forgery and tampering of the coded pattern are prevented.
Embodiments of the present invention are explained with reference to attached drawings.
As shown in
The card game apparatus 10 provides a soccer game in this embodiment, however, it can also provide other team games such as baseball, rugby, American football, and hockey.
On the large-size panel display 12, images, such as the whole soccer stadium image, a game digest of all seats, and a game result of all seats, are displayed. A game player participating in a game for the first time purchases a starter set (item) required for the game, and takes one of the seats each of which is provided with each of the terminal apparatuses 16a-16h. The starter set includes an integrated circuit card (memory card) 18 used as a recording medium that records an exercise result, a game result, etc., and eleven player cards 20 on each of which soccer player's photograph is printed.
Here, on the surface of each of the player cards 20, a photograph of different players is printed as described later, and on the back side, a data pattern (identification code) is recorded, which is for identifying the individual player printed on the surface. Further, on the integrated circuit card 18, at least, the kind of the player cards 20, and skill and past game results of the player corresponding to the card data of the player cards 20 are stored. Therefore, while data required for a game is obtained by reading the information stored in the integrated circuit card 18, a qualification of the game player 22 for participating in the game is checked.
Since the terminal apparatuses 16a-16h are configured identically, explanations hereunder are based on the terminal apparatus 16a.
The terminal apparatus 16a includes a player card arrangement panel 24 for laying the player cards 20 that the game player 22 owns, a monitor 26 that displays images of an exercise and a game of a soccer team organized by the game player 22, an integrated circuit card reader/writer 28 into which the integrated circuit card 18 is inserted, and a card issue unit 30 that issues a card to the game player after a game is over.

On the right-hand side of the player card arrangement panel 24, input buttons 34a and 34b that input player power etc. are provided. The game player 22 can give directions to a player during the exercise or the game by operating the strategy buttons 32a-32c. That is, the game player 22 operates the strategy buttons 32a-32c, directing, for example, tactics such as a side attack, a shoot to the goal, etc., and switching cameras for display on the monitor 26.
The main control unit 14 is connected to a large-size panel control unit 36 for controlling display of the large-size panel display 12 through a hub 40 of LAN (Local Area Network) 38, each of the terminal apparatuses 16a-16h, and an external network (not shown).
The large-size panel control unit 36 includes CPU 42, a memory unit (RAM) 44, an input-and-output interface 46, a sound circuit 48, and a graphic display circuit 50. A control program is stored in the memory unit (RAM) 44, the control program sorting out various image data (for example, the whole soccer stadium image, each player's playing image, a digest scene of an ongoing game, or a goal scene of past games, etc.) to be displayed on the large-size panel display 12, assigning a priority, and displaying images one by one. A switch 52 is connected to the input-and-output interface 46 for operating the main control unit 14 and the large-size panel display 12. The sound circuit 48 is connected to a sound amplifier 54 that outputs the sound according to the various images displayed on the large-size panel display 12. The graphic display circuit 50 displays the images (for example, the whole soccer stadium image, each player's playing image, the digest scene of the ongoing game, or the goal scene of the past game etc.) on the large-size panel display 12, the images being chosen by a control signal from CPU 42.
Further, each of the terminal apparatuses 16a-16h includes CPU 62, a memory unit (RAM) 64, an input-and-output interface 66, a sound circuit 68, and a graphic display circuit 70. The memory (RAM) 64 stores the various image data (for example, various game selection images, each player's playing image, etc.) to be displayed on the monitor 26, and the control program. The input-and-output interface 66 is connected to an integrated circuit card reader/writer 28, an image sensor 56 for reading the card data stored on the back of the player card 20, and a switch 72 for operating the monitor 26 in addition to the main control unit 14 is connected. The sound circuit 68 is connected to a sound amplifier 74 that outputs the sound according to the various images displayed on the monitor 26. The graphic display circuit 70 displays the images on the monitor 26, which are selected by the control signal from CPU 62.
As shown in
The player card 20 is placed on the upper surface of the play field sheet 80. Inside of the case 76, there are installed a luminous source 82 that irradiates infrared rays (invisible light) to the back of the player card 20 placed on the player card arrangement panel 24, a first filter 84 that removes visible light from the light emitted from the luminous source 82, an image sensor 56 that photographs a pattern of the card data stored on the back of the player card 20 placed on the player card arrangement panel 24, a first reflective board 86 that reflects upwards light reflected from the back of the player card 20, a second reflective board 88 that guides the light (invisible light) reflected by the first reflective board 86 to the image sensor 56, and a second filter 90 that removes disturbance light (visible light) contained in the light reflected by the reflective boards 86 and 88. The luminous source 82 includes a light emitting diode (LED) that emits the invisible light, which is not visible to naked eyes, such as infrared rays or ultraviolet rays. Of course, when the luminous source 82 does not emit any visible light, the first filter 84 can be dispensed with.
The first reflective board 86 is supported by a bottom inclination part 76b of the case 76 such that an inclination is provided at a predetermined angle α to the player card arrangement panel 24 that is prepared horizontally. Further, the second reflective board 88 is installed with an inclination at an angle according to the installation angle of the first reflective board 86.
Since the case 76 has the bottom inclination part 76b, when the game player 22 takes the seat, there is a room for the legs of the game player 22 under the bottom inclination part 76b. Therefore, when the game player 22 arranges the player card 20 on the player card arrangement panel 24, it is possible to extend a hand to an inner position of the player card arrangement panel 24, and allow the player card 20 to be placed at any desired position of the whole surface of the player card arrangement panel 24.
Since, inside the case 76, the infrared rays (invisible light) from which visible light is removed is irradiated by the luminous source 82 to the player card arrangement panel 24, the inside of the case 76 is not visible if viewed from the top of the player card arrangement panel 24.
As shown in
Further, the game player 22 can place eleven player cards 20 in the participation player card arrangement domain 92 out of the player cards 20 on hand, and can arrange up to 5 player cards 20 as alternate players in the alternate player card arrangement domain 94.
The strategy direction button 32a serves as a selection button that moves a cursor on a menu screen displayed on the monitor 26 upward, and the strategy direction button 32b serves as a decision button, and the strategy direction button 32c serves as a selection button that moves the cursor on the menu screen displayed on the monitor 26 downward.
The input button 34a is an operation button for changing parameters of the player cards 20 arranged in the participation player card arrangement domain 92 to a full-power state, and the input button 34b is an operation button for changing the parameters of the player cards 20 arranged in the participation player card arrangement domain 92 to a physical power preservation level.
The integrated circuit card 18 stores various data such as team capability (growth value) according to exercise, a game result with other teams and a title gained according to the game result. The game player 22 inserts the integrated circuit card 18 to the integrated circuit card reader/writer 28, such that the terminal apparatus 16, before starting a game, reads the data stored in the integrated circuit card 18.
As shown in
The domains 100, 102, 104, and 105 are printed with an infrared transmitting pigmented ink such that the card data (data including identification data and skill of the player printed on the card concerned) recorded on the back of the player card 20 can be recognized. Further, the alternate player card arrangement domain 94 is printed on the back of the play field sheet 80 in brown ink, and five yellow-colored line frames 106 are printed, where up to 5 player cards 20 of the alternative players can be placed.
Here, in the card game apparatus 10, each player printed on the player card 20 is assigned one of the positions, namely, a forward, a midfielder, a defender, and a goalkeeper. When the position assigned to the player matches with the domain in which the player card 20 is placed, a player parameter and a team parameter are set at a standard value.
However, when the position of the player assigned to by the player card 20 is different from the domain where the player card 20 is placed, the player parameter and the team parameter are set at a lower value. For example, when a forward (FD) player card 20 is placed in the defender domain 102, an offensive strength, for example, of the team will become weaker.
The game player 22 is the coach, and can decide which player card 20 is to be placed in each of the domains 100, 102, and 104. Further, the game player 22 can decide which formation to take from 3-3-4, 3-4-3, and 4-3-3 at the game start in terms of the number of the player cards 20 to be placed in each of the domains 100, 102, and 104.
As shown in
The minute unevenness 110 provided on the surface prevents the player card 20 from sticking, facilitating removal and replacement of the player card 20 placed. Further, since the play field sheet 80 has the minute unevenness 110 on the surface, light from the outside reflects diffusely, and it becomes semi-translucence, serving as a blinder for the inside of the case 76. Further, since the luminous source 82 emits the invisible light, the inside of the case 76 is pitch dark, and the inside of the case 76 is invisible for the game player 22 when viewed from the top of the player card arrangement panel 24.
In addition, for an ink layer 108, pigmented ink that transmits infrared rays other than black and white is used. This is because the card data is recorded by a black and white pattern, which is visible with the invisible light, on the back of the player card 20.
As shown in
Here, the card data 112 provides a memory domain 112d that is in a square shape defined by black frames 112a-112c on three sides, excepting top, namely, the left-hand side, the right-hand side, and the bottom, wherein each of a black part 112e and a white part 112f formed in the square represent one bit, and a black-and-white pattern configured by, for example, 8 bits in the vertical direction and 3 bits in the horizontal direction is printed such that it is detected.
Further, since only the top side of the card data 112 lacks of the black frame, angle of the player card 20 can be distinguished from the positions of the black frames 112a-112c. Further, since the circumference of the card data 112 is white, the outline of the card data 112 can be extracted easily.
On the player card 20, items such as a photograph of a player, the player's profile, and the like are printed with the ink that transmits the invisible light, and the card data 112 is further printed in over the images (such as the photograph and profile) with the ink that absorbs the invisible light such that it is not visible with naked eyes. Further, on the back of the player card 20, the card data 112 may be printed with the ink that reflects the invisible light, and the white part 113 may be printed with the ink that absorbs the invisible light, contrary to the above.
Although the card data 112 is printed on the back of the player card 20, it can be formed by methods other than printing (for example, seal attachment, magnetic data, etc.), not limited to this.
Here, a method configured to recognize the card data stored on the back of the player card 20 is explained.
As shown in
Here, as for a target dot, an adjoining dot on the left and an adjoining dot on the right of the target dot are selected, in the horizontal direction of bits to be read.
Thus, the noise resulting from the faulty dot of the image sensor etc. is removable. However, since resolution falls by the noise cut process, the noise cut process is not performed in the vertical direction.
At S12, spherical surface compensation filter process is performed such that distortion of the lens of the image sensor 56 is compensated. The spherical surface compensation filter process compensates the distortion of an image due to the distortion of the lens as shown in
First, an image coordinates after conversion (i, j) is converted into a coordinates (x y) wherein the center of the 640×480-dot image is defined as (0, 0), as shown in
x=(i−320)+0.5
y=(j−240)+0.5
Next, a distance d from the center of the coordinate, and an angle thereof of a dot that is being converted, as shown in
d=(x2+y2)1/2
a=arctan(y/x) when x>=0
a=arctan(y/x)+π when x<0
Further, the following calculations are performed, in order to obtain an original image coordinates (xx, yy) corresponding to the coordinates (x y), as shown in
First, an angle A is obtained from a length of an arc d and a radius R.
A=(d/2πR)×2π=d/R
dd=R×cos(A)
xx=dd×cos( A)
yy=dd×sin(A)
Then, the original coordinates (xx, yy) is converted to a coordinates in which the origin (0, 0) of the coordinates is the top left-hand side corner of the image, as shown in
ii=(xx+320)−0.5
jj=(yy+240)−0.5
Then, a value V of the dot at the coordinates (i, j) after conversion is obtained, as shown in
In this manner, an image without distortion as shown in
At S13, a standard marker position detection process is performed. As the standard marker position detection process, an outline extraction process of S13a and a pattern matching process of S13b are performed. As shown in
In addition, in the outline extraction process of the standard marker 114, the image data of the standard marker 114 is divided into nine sections, and the outline of the standard marker 114 is extracted using a Sobel filter.
At S14, the position and the angle of the player card 20 placed on the player card arrangement panel 24 are detected. The card position and angle detection process detects the number of the player cards 20 placed on the player card arrangement panel 24, a position coordinates and an angle of each of the player cards 20. In order to shorten time required of this detection, image resolution is made coarse, for example, to about ½ of the pixels of an image photographed by the image sensor 56, such that an approximate position and an approximate angle are obtained, with an accurate position and an accurate angle to be obtained in a later stage.
For this reason, the card position and angle detection process includes an approximate position and angle detection process S15 as a first phase, and an accurate position and angle detection process S16 as a second phase.
The approximate position and angle detection process 15 includes a reduction process, an outline extraction process, a pattern matching process, and a pixel skipping process.
In the outline extraction process S15a, the reduction process reduces the resolution of the image to ½ both vertically and horizontally, and makes the resolution coarse. Then, at S15b, the outline of the card data 112 stored on the back of the player card 20 is extracted using a Sobel filter. In the outline extraction process, each of the four sides of the outline of the card data 112 is divided into 3 sections, as shown in
At S15c, the pattern matching process is performed. That is, it compares with pattern data of each rotation position registered beforehand, and marks are given, while all images are searched with a dot being shifted at a time. Coordinates and the angles that give a value greater than a certain level are stored. Since the values obtained in this manner, unnecessary coordinates are also included, therefore, excessive pixels are skipped by the pixel skipping process at S15d.
At the position and angle detection process S16, a profiling process, an outline extraction process, and a pattern matching process are performed. At S16a, the profiling process performs profiling of an area near the location coordinates that is coarsely obtained by the approximate position and angle detection process. At the following S16b, the outline extraction process extracts the outline of the card data 112 stored on the back of the player card 20 by applying the cut image to the Sobel filter. At the following S16c, the pattern matching process compares with the pattern data of the rotation position beforehand registered like the pattern matching process of the approximate position and angle detection, and an accurate position and an accurate angle are obtained.
At S17, the luminosity of an image is profiled from the position coordinates and the angle that are obtained as above. Then, as shown in
Here, the card angle detection process shown in
At S21 of
Otherwise, if the luminosity of any areas profiled, namely, U0, U1 and U2 on the upper side, L0, L1 and L2 on the left-hand side, R0, R1 and R2 on the right-hand side, and D0, D1 and D2 of the bottom is not greater than the luminosity threshold value A, the process proceeds to S23. Then, it is checked whether only the areas L0, L1 and L2 on the left-hand side have a luminosity threshold value greater {smaller} than A, and the remaining areas have a luminosity threshold value greater than B. If the result of the check is affirmative, the process proceeds to S24 where it is determined that the player card 20 on the player card arrangement panel 24 is placed at such an angle that the left-hand side areas L0, L1 and L2 are located upwards.
Otherwise, if the result of the check is negative, the process proceeds to S25.
Then, it is checked whether only the areas D0, D1 and D2 of the bottom have a luminosity threshold value greater {smaller} than A, and the remaining areas have a luminosity threshold value greater than B. If the result of the check is affirmative, the process proceeds to S26 where it is determined that the player card 20 on the player card arrangement panel 24 is placed at such an angle that the bottom areas D0, D1 and D2 are located upwards.
Otherwise, if the result of the check is negative, the process proceeds to S27.
Then, it is checked whether only the areas R0, R1 and R2 on the right-hand side have a luminosity threshold value greater {smaller} than A, and the remaining areas have a luminosity threshold value greater than B. If the result of the check is affirmative, the process proceeds to S28 where it is determined that the player card 20 on the player card arrangement panel 24 is placed at such an angle that the right-hand side areas R0, R1 and R2 are located upwards.
Otherwise, if the result of the check is negative, the process proceeds to S29.
Then, it is checked whether only the areas U0, U1 and U2 on the upper side have a luminosity threshold value greater {smaller} than A, and the remaining areas have a luminosity threshold value greater than B. If the result of the check is affirmative, the process proceeds to S30 where it is determined that the player card 20 on the player card arrangement panel 24 is placed at such an angle that the upper side areas U0, U1 and U2 are located upwards.
Otherwise, if the result of the check is negative, the process proceeds to S22 where it is determined that the card data 112 is unreadable.
In this manner, the angle of the player card 20 placed on the player card arrangement panel 24 is detectable.
In addition, the black-and-white pattern of the card data 112 does not need to be in a rectangular form. As a variation, the card data 112 can take a ring-like form, as shown in
In this case, presence of a black projection area 118a that projects from the outer circumference of the black part 118 is detected, and when the black projection area 118a is detected, a bit recognition code 1 is given, and when the black projection area 118a is not detected, a bit recognition code 0 is given. In this manner, a 10-bit recognition code is obtained. Further, since the ring-like black part 118 projects in the shape of radiation from the outer circumference, the black projection area 118a is detected regardless of the angle of the player card 20. Further, a hatching area 120 that delimits the white area 116 may be printed by ink black or other in color, the ink having to be capable of reflecting invisible light so that the presence of the player card 20 can be detected.
As shown in
In an example shown in
In the case that the player card 20B is diagonally arranged on the player card 20A, although the four card points 122 of the player card 20B are detectable as shown in
In the case that the player card 20B is arranged approximately or completely overlapping the player card 20A as shown in
Here, how to play with the card game apparatus 10 constituted as mentioned above and control process thereof are explained.
The card game apparatus 10 reads team data and players' exercise data stored in the integrated circuit card 18, and the control process will start, when the game player 22 inserts a game fee (a coin) into a coin slot (not shown), the integrated circuit card 18 is inserted in the integrated circuit card reader/writer 28 and a start button (not shown) is operated to an ON position.
As shown in
The integrated circuit card 18 before a first use, basic values of registration players are stored as initial values. As a growth value is acquired from an exercise result and a game result, the value is added to each registration player's basic value. Evaluation items of the capability of every player include shooting, passing, dribbling, tackling, pass cutting, positioning, tactical understanding, stamina, speed, muscular strength, and special capability (a killer pass, pinpoint pass, etc.), for example. The basic value and the growth value for each of these items are stored as individual player's data.
In addition, the special capability is not set to ordinarily available player cards 20, but only a rare card issued in a small number is set up with a special capability that is reflected in a game as a player's individual data.
Further, when the integrated circuit card 18 cannot accept new registration due to memory reaching full, old individual data of the player card 20 has to be erased before the new registration is accepted. A game player 22 can select a player name to be eliminated when the memory of the integrated circuit card 18 is reaching full.
As shown in
In the member selection mode (step 1), the game player 22 chooses eleven player cards 20 as regular players, and five player cards 20 as alternate players from player cards 20 owned by the game player. Then, the game player 22 places the selected eleven player cards 20 as regular players at the forward domain 100, the midfielder domain 102, the defender domain 104, and the goalkeeper domain 105 (refer to
When the player cards 20 are arranged as above, the process moves to the player exercise mode S12. Here, although up to five alternate player cards 20 can be placed on the alternate player card arrangement domain 94, no alternate player cards 20 may be placed in the alternate player card arrangement domain 94, if, for example, the game player 22 has only 11 regular player cards.
In the player exercise mode (step 2), arbitrary exercise can be performed and each player and a team can be grown up satisfactorily before playing a game. The exercise will be automatically ended, when a predetermined time set up beforehand elapses.
In the following game mode (step 3), if preparation is completed, a game is arranged and a match will be played against a team of another player. When no other players are available, a match will be played against a virtual team of computer control.
If the game is started, the game player 22 considers tactics as a coach, looking at the progress situation of the game displayed on the monitor 26, and moves each player card 20 placed on the player card arrangement panel 24, directs a player, and changes the players. The game will be automatically ended upon elapse of a predetermined time.
In the following instruction mode (step 4), guidance is given to each player after carrying out the game. It is configured such that a player's unexpected capability grows up, and capability (skill) of each player's is enhanced. Then, a new player card 20 is issued from the card issue unit 30 at the end. Thus, since one player card 20 increases in number at a time whenever a game is completed, it becomes easy to select and change players in subsequent games.
As shown in
At step 12, the player cards 20 on hand are arranged on the player card arrangement panel 24, players are selected, and preparations of each selected player are made before the game. A set play, a formation, a shot, etc. are exercised as the preparation before the game to each player defined by the player card 20 placed on the player card arrangement panel 24 (exercise mode).
At step 13, a game is played with a team of another player. The game includes a first half (45 minutes), a halftime meeting, and a second half (45 minutes). During the game, the game player 22 moves the player cards 20 according to a situation of the game such that a formation is changed, a player card 20 is replaced, and tactics is changed. Further, in the halftime meeting, direct directions (encouragement, determining tactics and the like) may be given, the formation may be changed, and a player may be replaced.
At step 14, a meeting after the game is held such that communications are performed with the players, such as explaining points to be reflected of the game, and the like, which raises a player's growth value (instruction mode).
At step 15, a game result is released as sport news. In this manner, the game player 22 enjoys the game as the coach of the soccer team, capable of assigning positions to the players, and raising the capability (skill) of the players.
Next, an explanation about a control process of CPU 62 of the terminal apparatus 16 follows, with reference to
As shown in
At S43, data that was read by the integrated circuit card reader/writer 28 is checked. When there is no club data in the data read by the integrated circuit card 18, the process progresses to S45, a club name input screen is displayed on the monitor 26, prompting the game player to input the club name at S44. Then, a uniform selection screen is displayed on the monitor 26, prompting the game player 22 to select a uniform of his/her team at S46. Then, a team flag selection screen is displayed on the monitor 26, prompting the game player 22 to select the team flag at S47.
When the club data is detected in the data read by the integrated circuit card 18 at S44, or after processing the above S45-S47, the process progresses to S48 and a club data check screen is displayed on the monitor 26. Then, at S49, an opponent team display screen is displayed on the monitor 26.
At S50, a player card arrangement direction screen is displayed on the monitor 26. Here, the player card arrangement direction screen displays, for example, “Arrange cards on the board.” Further, a timer starts counting down time allowed (e.g. 60 seconds) for arranging the player cards 20.
At S51, a system arrangement plan (for example, a configuration figure as shown in
At S52, when the game player 22 arranges at least eleven player cards 20 serving as a starting lineup on the player card arrangement panel 24 as shown in
At S56, the exercise screen before the game is displayed on the monitor 26. As an exercise screen, an exercise menu screen 130 as shown in
A meeting screen before the game is displayed on the monitor 26 at the following S57. Then, at S58, the process waits for an opponent team to be prepared.
At S59 shown in
At S61, a first half game screen 136 is displayed on the monitor 26 of the game between the team of the game player team and the opponent team led by another game player. Immediately after the kickoff, the game player 22 sees a motion of each player displayed on the monitor 26 with the eleven player cards 20 being in place as arranged at the beginning with a starting lineup on the player card arrangement panel 24 as shown in
At 20 minutes into the first half, for example, the game player 22 moves positions of the player cards 20 on the player card arrangement panel 24 such that the formation is shifted into an offensive formation as shown in
That is, the game player 22 makes the offensive formation by moving a midfielder player card 20 to the forward domain 100 on the player card arrangement panel 24, so that the midfielder player can participate in an offense with the forward players. An offensive formation screen 137 is displayed on the monitor 26.
After the first half of the game, the process progresses to the following S62 and a halftime meeting screen is displayed on the monitor 26. In this halftime meeting, the coach gives directions to the players, and determines whether the players understand the tactics. Further, during the halftime, as shown in
At S63, the second half of a game is displayed on the monitor 26 after the halftime meeting. At 35 minutes, for example, into the second half, the game player 22 selects to change the formation into a defense formation in order to put importance to defense in the remaining time of the game, attempting to keep the scoring lead as shown in
At the following S64, it determined whether the score is in a tie. When the score is in a tie, the process progresses to S65 and a game screen of an extra-time is displayed on the monitor 26. During the extra-time, in order to open the scoring, the offensive formation will be adopted where midfielder player cards 20 are pushed to the forward domain 100 on the player card arrangement panel 24, and the midfielder players join the forward players in the offense.
After the extra-time is finished, the process progresses to S66 and points of both teams are checked to determine whether the score is in a tie. If the score is in a tie, the process progresses to S67 where each team selects 5 preferred shooters, and a PK round starts, one by one alternately. A penalty kick screen is displayed on the monitor 26.
When the score is not in a tie at S64, or after the penalty kick round of S67 is completed, the process progresses to S68 and a game result announcement screen 140 is displayed on the monitor 26. As shown in
At S70, parameters of each player and the team are calculated from the game result. Then, the integrated circuit card 18 stores the calculated parameters at S71. At S72, it is determined whether a new game is requested. When the game player 22 opts to finish playing, the process progresses to S73, a new player card 20 is issued from the card issue unit 30, and the integrated circuit card 18 is returned from the integrated circuit card reader/writer 28. Further, at S72, when a game player 22 selects to play a new game continuation, the process returns to S41 shown in
Here, the process of integrated circuit card determining at S43 above is explained with reference to
As shown in
At S83, a signal indicating that a new integrated circuit card 18 is inserted in the integrated circuit card reader/writer 28 is waited. Then, in S84, when insertion of an integrated circuit card 18 to the integrated circuit card reader/writer 28 is detected, the process returns to S80, and the new integrated circuit card 18 inserted in the integrated circuit card reader/writer 28 is checked for its legitimacy. If the new integrated circuit card 18 is determined to be legitimate, the integrated circuit card check process is ended.
Here, the process of player card arrangement check at S53 above is explained with reference to
As shown in
If it is determined at S91 that there are no overlapping player cards 20, the process progresses to S94, and then it is checked whether the same player cards 20 are placed. If it is determined at S91 that the same player cards 20 are placed, an instruction for rearrangement of the player cards 20 is displayed to the game player 22 at S92. Then, at S93, it is checked whether the player cards 20 are rearranged.
If it is determined that the same player cards 20 are not placed at S94, the process progresses to S95, and it is checked whether the number of the player cards 20 placed on the player card arrangement panel 24 is proper. It is determined at S95 whether the number of the cards is proper. If eleven player cards 20 are placed in the participation player card arrangement domain 92 of the player card arrangement panel 24 and five or less player cards 20 are placed in the alternate player card arrangement domain 94 by S95, this player card arrangement is determined proper, and the check process is ended. Otherwise, if the number of cards is determined to be improper at S95, an instruction for rearrangement of the player cards 20 is displayed to the game player 22 at S92. At S93, it is checked whether the player cards 20 are rearranged.
Here, the process of player card check during a game is explained with reference to
As shown in
Otherwise, if it is determined at S101 that there are no overlapping player cards 20, the process progresses to S103, and it is determined whether the same player cards 20 are placed. If it is determined at S103 that the same player cards 20 are placed, it indicates to the game player 22 that the arrangement of the player cards 20 is inadequate unsuitable at S102.
If it is determined at S103 that the same player cards 20 are not placed, the process progresses to S104 and it is determined whether the number of the player cards 20 placed on the player card arrangement panel 24 is proper. Since the number of cards is proper when eleven player cards 20 are placed on the participation player card arrangement domain 92 of the player card arrangement panel 24 and five or less player cards 20 are placed on the alternate player card arrangement domain 94 as checked at S104, the process progresses to S105 where it is determined whether the arrangement data of the player cards 20 read this time is in agreement with the starting lineup data at the start of the game. If a player card 20 different from the starting lineup is placed when the arrangement data of the player cards 20 read by S105 this time, the process progresses to S102 where the game player 22 is alerted that the arrangement of the player cards 20 is in adequate.
When the arrangement data of the player cards 20 read by S105 this time is in agreement with the starting lineup data, the process progresses to S106 and it is determined whether the player cards 20 of alternate players are placed on the alternate player card arrangement domain 94. When it is determined at S106 that there is a player card 20 of an alternate player, the process progresses to S107 and displays that a player replacement is possible on the monitor 26.
At S108, player position data is corrected from the arrangement of the player cards 20 so that the present arrangement data can be adapted to the game. At S109, the arrangement data of the player cards 20 read this time is recorded as new arrangement data.
Thus, if the game player 22 moves a player card 20 and the formation is changed, the contents of the game according to the changed formation is immediately displayed on the monitor 26. When a player card 20 of an alternate player is placed in the alternate player card arrangement domain 94, the player card 20 can replace a present player. When the individual data of the changed player card 20 is recorded as new arrangement data, the image of the player who took the place is displayed on the monitor 26.
As shown in
When there is a seat with no game player, a computer team registered in CPU 62 of the terminal apparatus 16 plays a game.
When a team has finished a game with the 7 teams, three games are played, namely, the first round game of the world club championship, the semifinal game of the world club championship, and the final match of the world club championship. The world club championship is an international competition in which only teams ranked higher than the 50th place of an international ranking can participate. Teams that cannot participate in the world club championship (for example, a team having lost four or more games with the 7 teams) can participate in a local convention.
As shown in
The second cycle (the champion league) 152 is a league match by 4 teams of higher ranks according to the game result of the tournament system of 8 teams. A first game of the champion league, a second game of the champion league, and a third game of the champion league are held by the 4 teams of higher ranks. {Is above logically OK? round-robin/league}
Ten kinds of such game cycles are prepared, that is, eight other cycles are prepared in addition to the first cycle (the world club championship) 150, and the second cycle (the champion league) 152, the cycles being performed repeatedly.
As shown in
At S113, it is determined whether an integrated circuit card (memory card) 18 is inserted in the integrated circuit card reader/writer 28. If it is determined that the integrated circuit card 18 is not inserted in the integrated circuit card reader/writer 28 at S113, the process returns to S112 where the advertisement screen is displayed on the monitor 26 of the terminal apparatus 16, and the message such as “Insert an integrated circuit card” is displayed on the monitor 26.
If it is determined at S113 that an integrated circuit card 18 is inserted in the integrated circuit card reader/writer 28, the process progresses to S114 where the coin shot prepared in the coin slot (not shown) is unlocked, being prepared for accepting a coin (coin accepting means). Then, at S115, a message such as “Insert a coin” is displayed on the monitor 26. After this, the process progresses to S42 mentioned above.
Thus, in the process prior to a game start, it is determined that a would-be game player 22 owns an item necessary for the card game, that is, a club card in which card data of the player cards 20 is stored. If the would-be game player 22 inserts an integrated circuit card 18 in the integrated circuit card reader/writer 28, and the inserted integrated circuit card 18 is determined to be a legitimate card, coin insertion is permitted. In this manner, coin insertion is prevented unless the would-be game player 22 owns a legitimate integrated circuit card 18, avoiding a trouble about returning the coin.
Here, an example of variation the present invention is explained.
As shown in
The would-be game player 22 inserts an already purchased integrated circuit card 18 in the integrated circuit card reader/writer 28, when participating in the card game concerned. If the would-be game player 22 is a beginner, a starter set should be purchased in advance. The starter set includes an integrated circuit card 18 and eleven player cards 20.
At S121, it is determined whether the integrated circuit card 18 is inserted in the integrated circuit card reader/writer 28. At S121, if it is determined that the integrated circuit card 18 is inserted in the integrated circuit card reader/writer 28, the process progresses to S122, where it is determined whether the integrated circuit card 18 inserted in the integrated circuit card reader/writer 28 is a legitimate card. The integrated circuit card 18 stores at least the kind of the card, skill of a player corresponding to card data, and past game results. Therefore, data required for a game is obtained, and legitimacy of the would-be game player 22 is determined by reading the information stored in the integrated circuit card 18.
If it is determined at S122 that the integrated circuit card 18 inserted in the integrated circuit card reader/writer 28 is not a legitimate card, the process progresses to S123 and a warning screen (an illegitimate card display) is displayed on the monitor 26. Then, the integrated circuit card reader/writer 28 by S124 discharges the integrated circuit card 18 that is determined illegitimate. Then, the process returns to S120 again and the standby screen that prompts insertion of an integrated circuit card 18, and the advertisement screen are displayed on the monitor 26.
If it is determined at S122 that the inserted integrated circuit card 18 is legitimate, the process progresses to S125, where it is determined whether club data is stored in the integrated circuit card 18. If the club data is stored in the integrated circuit card 18, the process progresses to S126, and the club data read from the integrated circuit card 18 is displayed on the monitor 26.
At S127, accepting coin insertion starts (payment of a game fee). The process progresses to S128 where it is determined whether a coin is inserted. If it is determined at S128 that there is no coin inserted, the process progresses to S129 where it is determined whether a time limit set up beforehand passed. If it is determined at S129 that the time limit has not passed, the process returns to S128 and coin insertion is checked again.
If it is determined at S129 that the time limit passes, the process returns to S124 and the integrated circuit card 18 is discharged in order to prevent delay of a game start. Then, the process returns to S120 where the standby screen prompting insertion of an integrated circuit card 18, and the advertisement screen are displayed on the monitor 26.
If it is determined at S128 that there is a coin inserted, the process progresses to S130 where it is determined whether paid amount reaches the amount of the game fee. If it is determined that the paid amount does not reach the game fee, the process progresses to S129 where the predetermined time limit is counted, during which whether an additional coin is inserted is determined.
If it is determined at S125 that club data is not stored in the integrated circuit card 18, the process progresses to S131 where a guidance screen explaining steps to create a club to the would-be game player 22 is displayed on the monitor 26. Then, at S132, an input screen G01 for inputting a club name is displayed on the monitor 26. At S133, a uniform creation screen G02 is displayed on the monitor 26 such that uniforms that player of the team of the would-be player will wear. Specifically, a uniform for “home”, a uniform for “away”, a uniform for a goalkeeper, and a team flag are created through this screen.
At S134, a team sponsor selection screen G03 (50 company names are listed) is displayed on the monitor 26, and ten companies are to be selected as main sponsors and sub sponsors. Then, at S135, a screen illustrating the completion of the club establishment of the team concerned is displayed on the monitor 26.
Then, at S136 shown in
Next, a display process of a clubhouse is performed commonly to all the seats (the terminal apparatuses 16a-16h).
At S138, a clubhouse screen (a card arrangement direction) is displayed on the monitor 26. In the clubhouse screen, a direction to the game player 22 to arrange player cards 20, and an arrangement of the starting lineup of a game performed last time from the past game data stored in the integrated circuit card 18 are displayed on the monitor 26. Further, a uniform number of each player is set up automatically, and displayed on the monitor 26.
At S139, it is determined whether the player card 20 is placed on the player card arrangement panel 24. On the player card arrangement panel 24, it is possible to place eleven cards as the starting lineup and three {not 5? why 3? because this is a variation?} cards of alternate players. At S140, the card data of each player card 20 placed on the player card arrangement panel 24 is read, and arrangement of each player card 20 is checked.
At S141, it is determined whether the arrangement of each player card 20 placed on the player card arrangement panel 24 is proper. If affirmative, the process progresses to S142, where it is determined whether the starting lineup is decided by reading the card data of each player card 20 placed on the player card arrangement panel 24 within a predetermined time limit.
If it is determined at S142 that a starting lineup is decided within the time limit, with each player card 20 placed on the player card arrangement panel 24, the starting lineup is registered into the memory 64 of the terminal apparatus 16 at S143.
If it is determined at S141 that the arrangement of each player card 20 placed on the player card arrangement panel 24 is unsuitable, the process progresses to S144, where it is determined whether the time limit (for example, 60 seconds) has elapsed. If it is determined at S144 that the time still remains, the process returns to S139 and the process after S139 is performed.
If it is determined at S144 that the time limit (for example, 60 seconds) has elapsed, the process progresses to S145, where the arrangement data of each player card 20 is compulsorily corrected based on the past game result. Then, at S146, a starting lineup is automatically decided according to the corrected arrangement data of each player card 20, and the starting lineup is displayed on the monitor 26. Then, the process progresses to S143, where the starting lineup is registered into the memory 64 of the terminal apparatus 16.
At S147, the clubhouse screen (starting lineup decision) is displayed on the monitor 26, and the starting lineup is displayed on the monitor 26.
Then, at S148 shown in
At S149, if an item of the exercise is selected from the exercise menu within the time limit, the process progresses to S150, where a clubhouse screen (exercise result) is displayed on the monitor 26, and a team capability change screen updated by the exercise is displayed on the monitor 26.
If no items of the exercise are selected within the time limit at S149, an automatic menu decision screen is displayed at S151, then at S150, the clubhouse screen (exercise result) is displayed on the monitor 26, and the team capability change screen updated by the exercise is displayed on the monitor 26.
Following the above, a stadium screen is displayed simultaneously to the whole seats, and an operation process of a kickoff is performed. At S153, scenes prior to the kickoff (player entrance etc.) are displayed on the monitor 26.
Then, at S154, an operation process of a game with an opponent team is performed. At S155, scenes after the game (joy of the players of a team that wins the game, display of a game result, etc.) are displayed on the monitor 26.
At S156 shown in
At S158, it is determined whether a choice is made of the management menu selection screen within a time limit. If it is determined at S158 that a choice is made of the management menu selection screen within the time limit, the process progresses to S159, where a clubhouse screen (management result) is displayed on the monitor 26, and a team capability change screen updated according to the game result and the meeting is displayed on the monitor 26.
If it is determined at S158 that no choice was made of the management menu selection screen within the time limit, the process progresses to S160, where a choice is made compulsorily of the management menu selection screen, and the process progresses to S159.
At S161, the data of the game result is stored in the integrated circuit card 18. Then, the process progresses to S162 and a continue screen (game continuation check screen) is displayed on the monitor 26. Then, at S163, it is determined whether the card game is to be continued. If it is determined at S163 that the game player 22 does not choose the continue (game continuation) within a time limit (for example, 10 seconds), the process progresses to S164, where the integrated circuit card 18 is discharged, and the card game ends.
If it is determined at S163 that the game player 22 chooses the continue (game continuation) within the time limit (for example, 10 seconds), the process returns to S136 of
In
If it is determined at S171 that there is no player card 20 of which card data cannot be read, the process progresses to S173, where it is determined whether there are player cards 20 overlapped each other on the player card arrangement panel 24. If it is determined at S173 that there are overlapping cards, the process progresses to S174 where a rearrangement direction announcement is issued.
If it is determined at S173 that there are no overlapping cards, the process progresses to S175, where it is determined whether there are any identical cards. If it is determined at S175 that there are identical player cards 20 placed on the player card arrangement panel 24, the process progresses to S176, where a rearrangement direction announcement is issued.
If it is determined at S175 that there are no identical cards, the process progresses to S177, where it is determined whether there are a correct number of player cards 20 (11 cards when it is a soccer game) placed on the player card arrangement panel 24. If it is determined at S177 that the number of the player cards 20 placed on the player card arrangement panel 24 is not eleven, being improper for the soccer game, the process progresses to S178, where a rearrangement direction announcement is issued.
Thus, at S170-S178, the card data of each player card 20 placed on the player card arrangement panel 24 is read, and it is determined that each player card 20 is arranged in the proper state, such that it is determined that a game can start, each player card 20 being properly arranged.
At S211 shown in
At S212, card arrangement of the last game is read from the past game data stored in the integrated circuit card 18. Then, at S213, the card arrangement of the last game and the present arrangement of the player cards 20 are compared.
At S214, the card data of the player card 20 that is unreadable is assumed from the last card arrangement is assumed, and the assumed card data is stored into the memory 64.
Then, the process progresses to S215 where it is determined whether the game player 22 owns the player card 20 of the card data assumed at S214. If it is determined at S215 that the game player 22 owns the player card 20 of the presumed card data, the process progress to S216, where the card data of the player card 20 that is unreadable is replaced with the assumed card data (corrected card data generation means). Then, the process progressed to S146 described above.
If it is determined that the game player 22 does not own the player card 20 corresponding to the assumed card data, the process progresses to S217, where a player having capabilities similar to the assumed card data is selected, and the card data of the selected player is registered into the memory 64 as alternative card data for the coordinates position (position where the unreadable player card is placed) (alternative card data providing means).
In this manner, even when card data cannot be read by secular change, etc. of the player card 20, it becomes possible to start the card game, using alternative card data instead, and the game delay due to inability to read the card data is prevented. Further, when the card data of the player card 20 cannot be read as mentioned above, the game delay due to inability to read the card data is prevented by reading the card data of the past game corresponding to the arrangement of the unreadable card out of the card data stored in the integrated circuit card 18 that serves as a storage means, and generating alternative card data.
In
At S182, when no directions for the second half for each player are inputted, the process progresses to S183, where “no directions” is automatically chosen, and displayed on the monitor 26. At S184, the locker room screen of each player and the team state updated by the directions are displayed.
At S185, the progress situation of the second half of the game from the kickoff of the second half to the end is displayed on the monitor 26. After the second half of the game is finished, it is determined at S186 whether the score is in a tie. When it is determined at S186 that the score is in a tie, the process progresses to S187, where the extra-time game screen is displayed on the monitor 26. If it is determined at S186 whether the score is in a tie as the result of the extra-time, the game is over and the process progresses to S155.
After the extra-time is completed, the process progresses to S188, where it is determined whether the score is in a tie. If it is determined at S188 that the score remains in a tie, the process progresses to S189 and the screen of PK (penalty kick) game is displayed on the monitor 26. If it is determined at S188 that the score is not in a tie as the result of the extra-time, the game is over, and the process progresses to S155.
Here, a control process of the main control unit 14 that coordinates with the control process performed by each of the terminal apparatuses 16, and controls the display of the large-size panel display 12 is explained with reference to
As shown in
(2) While each terminal apparatus 16 processes S138 (a clubhouse screen, card arrangement, a starting lineup decision), the main control unit 14 displays the next game combination display screen G12 on the large-size panel display 12 at S192, and then, at S193, displays a convention data screen of a league, and a ranking and tournament table screen G13 on the large-size panel display 12.
(3) While each terminal apparatus 16 processes S148 and S150 (a clubhouse screen, team exercise, exercise menu selection, exercise scene, and exercise result display) and S152 (scene of movement to the stadium, player movement, and stadium atmosphere), the main control unit 14 at S194 displays introduction screens G14 that contain introduction of each team (matching team names of a stadium, teams' capability, a starting lineup, anticipated formation, etc.) on the large-size panel display 12.
(4) While the terminal apparatuses 16 of all seats simultaneously process S153 (a kickoff scene, and player entrance scene), the main control unit 14, at S195, displays a soccer relay broadcast program screens G15 (greeting of a site announcer, etc.) on the large-size panel display 12. Then, a kickoff (kickoff) scene is displayed on each terminal apparatus 16 and the large-size panel display 12.
(5) While each terminal apparatus 16 processes S180 (a game screen, the first half), the main control unit 14, at S196, displays a soccer relay broadcast program screen G16 (all game digest screen) on the large-size panel display 12, as shown in
(6) While each terminal apparatus 16 processes S181 and S184 (a locker room screen, and directions during the halftime), the main control unit 14, at S197, displays a soccer relay broadcast program screen G17 (the result of the first half of the game, CM image, etc.) on the large-size panel display 12.
(7) While each terminal apparatus 16 processes S185 (a game screen, second half), the main control unit 14, at S198, displays a soccer relay broadcast program screen G16 (all game digest screens) on the large-size panel display 12.
(8) While each terminal apparatus 16 processes S155-157 and S162 (a game end scene, a movement scene to the clubhouse, club management, continue screen), the main control unit 14, at S199, displays soccer relay broadcast program screens G18 (situation of a winning team and all game results, ranking table), and G19 (announcement of best eleven, program ending) on the large-size panel display 12.
In this manner, the large-size panel display 12 displays the game display screen G11, the game combination display screen G12, the convention data screen and the ranking and tournament table screen G13, the introduction screen G14, the soccer relay broadcast program screen G15, the soccer relay broadcast program screen G16, and the soccer relay broadcast program screens G17, G18, and G19, one by one according to the flow of the game played between terminal apparatuses 16. Therefore, while being able to prevent waiting customers from boring by the display through the large-size panel display 12, the fun of the game can be advertised to new customers who have not participated in a game, and an efficient marketing can be performed.
Here, a digest scene process is explained, in which digest scenes are extracted from the games, sequential order of the scenes is decided, and the digest scenes are arranged according to the sequence.
As shown in
The memory 44 of the large-size panel control unit 36 of the main control unit 14 stores the image data of the digest scenes stored in the memory 64 of each terminal apparatus 16 with the ranking (Good1, Good3, Good5, and so on) in that sequence, as shown in
As shown in
Here, typical digest scenes will include (1) an assist scene before shooting, (2) a shooting scene, (3) a goal scene (or a goalkeeper's shoot cutting scene), (4) a goal shooter's performance scene, and (5) an excitement scene of the spectator immediately after the goal, etc., for example. As for putting the sequential order, a higher priority may be given to a goal scene, and a set of the five scenes as described above is stored as a digest scene in the memory 64.
The typical digest scenes may include a corner kick scene, a penalty kick scene by a foul act in the penalty area, a free kick scene outside of the penalty area, a throw-in scene near the goal, etc. that are stored in the memory 44, where there are no goal scenes.
Image data of each digest scene contains recognition data such that the digest scene of each game can be easily distinguished by the main control unit 14 and each terminal apparatus 16, and it is possible to extract a digest scene automatically.
Here, a display data generation process of the large-size panel display 12, which the main control unit 14 performs is explained with reference to
As shown in
At S204, digest scenes are sequentially arranged, stored in the memory 44 of the large-size panel control unit 36 (refer to
Thus, the digest scene of a game is displayed on the large-size panel display 12, or a past game scene is selected and displayed on the large-size panel display 12 if a digest scene of a game is not available, thereby waiting customers are prevented from getting bored while waiting for a turn, and the fun of the game can be advertised to new customers who have not participated in a game, and an efficient marketing can be provided.
If no digest scenes are available in the memory 64 of each terminal apparatus 16 at S202, the process progresses to S206, where a score in progress of a game (a score, etc.) is stored in the memory 64 during the game. At S207, game data of a final match is read from a database (not shown) in which the past game data is accumulated, the game data of the final match is stored in the memory 64. Then, at S208, CM data of the sponsoring company is read from the database, stored in the memory 64.
At S209, the score in progress, the past game data, and the CM data are arranged in a desired sequence, and stored in the memory 64. At S205, the score in progress, the past game data, and the CM data are displayed on the large-size panel display 12 as arranged at S209.
Thus, when the digest scene of each game is not available among two or more games, the progress information on the game under present execution, the past game data, CM data, etc. is displayed such that the waiting customers will not get bored, the fun of the game can be advertised to the new customers who have not participated in the game, and the efficient marketing is provided.
Here, the second variation of the player card 20 is explained
As a flat coded pattern to be arranged on the back of the player card 20, a 2-dimensional bar code is available However, the card game apparatus 10 of the present invention requires that not only the ID code for discriminating a card but the position and direction (angle) of the coded pattern printed on the back of the player card 20 are detected. If the ID code, the position and the direction of the image data photographed by the image sensor 56 are to be analyzed simultaneously, the number of parameters in an operation process performed in an operation circuit will increase, and detecting all coded patterns will take considerable length of time.
There is a method to process the operation at a high-speed, wherein the data is processed one by one, and only necessary data is screened and unnecessary data is eliminated. However, a conventional 2-dimensional bar code having a square shape has to be read from one direction that is diagonal to the bar code. For this reason, and since the position and the direction of the player card 20 have to be read, increasing the number of the parameters, any additional parameters cause the processing time to become extensive.
Then, in this variation, a circular coded pattern is used for position detection of the card data 112 printed on the back of the player card 20. Then, the position detection process and the direction (angle) detection process can be divided, realizing a fast operation of the position detection process. Then, if the angle detection is performed to the position (coordinate) of the player card 20, which has been obtained, processing time required for the direction detection will be decreased. If a decoding process of the ID code of the card is carried out to the position data and the direction data, the operation process of the ID code can be performed at a high speed.
Accordingly, in this variation, detections of the card position (coordinates), the card direction (angle) and the ID code, which are obtained by reading data patterns recorded on the back of the player card 20, are performed in three separate stages. First, the position coordinates of the player card 20 is detected by covering almost the whole area of the player card arrangement panel 24 (step 1), then the angle detection is performed to the position coordinates that are detected (step 2), and then, the ID code decoding process (step 3) is carried out using the position coordinates and the angle that are determined.
As shown in
Further, the coded pattern 170 is printed in ink that transmits infrared rays, and such that a game player cannot recognize visually. Therefore, forgery and modification of the coded pattern 170 are prevented.
The card position detection circle 172, the position and angle detection pattern domain 174, the ID data domain 176, the annular white domain 178, and the data domain 180 of the coded pattern 170 are formed in the shape of a concentric circle, the center being on the central point 182. The ID data domain 176 having a larger radius than others is formed in an arc shape, because its radius is larger than the shorter side of the card 20. Namely, the ID data domain 176 is recorded in the arc shape, i.e., parts of the perimeter, providing a high efficiency in using the whole surface of the card.
When the coded pattern 170 is photographed by the image sensor 56 as shown in
That is, a bit signal is configured by the black part and the white part. According to predetermined contents, arrangement of the patterns configured by the black part and the white part vary, and the arrangement pattern of the black part and the white part functions as a coded pattern. In addition, in the present embodiment, a half bit (one black part or one white part) is represented by six dots on the screen of the image data photographed by the image sensor 56.
With the card game apparatus 10 mentioned above, the positions where the player cards 20 are placed on the sheet 80 for the play field are variable, and the directions of the player card 20 are not uniform and variable. Therefore, before detecting the coded pattern 170 printed on the back of the player card 20, detection of the position and the direction (angle) is necessary.
In view of this, the present embodiment detects the code position (center position) from the coded pattern 170 of the player card 20 by detecting luminosity difference between the inner side and the exterior side of the card position detection circle 172. For this purpose, white domains 171 {178?} and 173 {170?} are annularly formed inside and outside, respectively, of the card position detection circle 172. In this manner, the luminosity of the card position detection circle 172 is clearly distinguishable from the luminosity of the inside and the outside of the card position detection circle 172. The card position detection circle 172, being a circle, enables to detect the card position regardless of the direction (angle) of the card 20.
Further, in order to determine the position and angle (direction of the card 20) of the coded pattern 170, projecting parts 174a through 174d are provided in varied intervals that are detected and distinguished, the projecting parts being in the position and angle detection pattern domain 174, and projecting outward from the outer circumference of the card position detection circle 172 in the shape of radiation. The intervals of the projecting parts 174a through 174d in the direction of the circumference are arranged in varied intervals such that the position and angle of the card 20 are distinguished by detecting the intervals.
Further, a value of each bit is determined from the luminosity difference of two adjacent half-bit domains. In order to minimize an adverse affect of a blur and an error when detecting the position and the angle, the boundary of the half-bit domains is not used, but the luminosity of a central area of each domain is extracted.
As shown in
As shown in
Here, the card position coordinates detection process that CPU 62 of the terminal apparatus 16 performs is explained.
First, if the player card 20 is placed on the play field sheet 80, the position coordinates of the player card 20 are detected. By detecting the card position detection circle 172 that provides the circular coded pattern, the position coordinates is detected at a high speed, and without being influenced by the position and angle of the card 20.
Here, in the card position coordinates detection process, the position of the card 20 is detected by measuring the luminosity difference between the black part of the card position detection circle 172, and the white domains formed in the inner side and the outer side of the card position detection circle 172 of the coded pattern 170 shown in
As shown in
The arrangement pattern of the white point 182 and the black point 184 is shown in
Here, the evaluation value of the hatching part showing the card position detection circle 172 is set at zero. Then, coordinates at which all of the evaluation values of the 12 domains exceed a threshold value A, and ten (variable by setup) values exceed a threshold value B are made candidate coordinates of the card, and the values are stored. At this time, the sum of the evaluation values of all the domains is stored as an evaluation value N of the coordinates.
Next, the card coordinates stored as the candidate are evaluated by using a 12-division pattern 188 shown in
The arrangement pattern of a white point 190 and a black point 192 is shown in
Four pairs of points, a pair consisting of the white point 190 and the black point 192, are provided in each of the 12-division domains R1 through R12. Here, the white point 190 represents a positive luminosity value, and the black point 192 represents a negative luminosity value. The luminosity values are added for each domain, and the sum is made an evaluation value of each of the domains R1 through R12. The evaluation value of a hatching part is set to 0. Coordinates at which all of the evaluation values of the domains R1-R12 exceed a threshold value C, and nine (variable by setup) values exceed a threshold value D, are stored as a candidate of the card coordinates. At this time, the sum of the evaluation values of all the domains R1-R12 is stored as an evaluation value M of the coordinates. The evaluation value N and the evaluation value M are added to make an evaluation value Σ of the coordinates.
When either finishing evaluating all coordinates or the number of candidate coordinates exceeding a predetermined number, the candidate coordinates are culled out by deleting coordinates with a small evaluation value, where two or more candidate coordinates are located closer than a predetermined culling distance. Coordinates with a large evaluation value, which remains after the culling, are made the coordinates of the player card 20.
Next, the card angle detection process performed after card position detection is explained with reference to
As shown in
The position and angle (direction) of the player card 20 placed on the play field sheet 80 is determined as follows. Each of intervals L1 through L4 in the direction of the circumference, and relative to the projected parts 174a through 174d that project outward from the outer circumference of the position and angle detection pattern domain 174 take predetermined values, each of the intervals L1 through L4 satisfying L1<L2<L3<L4. Therefore, by scanning detection positions of the projected parts 174a through 174d, the position and angle of the player card 20 are obtained by the time interval of detected pulses.
In the present embodiment, the pattern of the detected pulses concerning the projected parts 174a through 174d is compared with a pattern beforehand remembered, such that the angle detection is performed by pattern matching technique.
For example, width (dimension in the direction of the circumference) of each of the projecting parts for angle detection 174a through 174d is set to 1, a ratio of intervals L1:L2:L3:L4 defined by 174a through 174d is set to 3:4:5:8. Thus, incorrect recognition of angle detection is prevented from occurring by providing the different value to the intervals L1 through L4.
Here, instead of changing the intervals L1-L4 between the projects parts 174a through 174d, width (dimension in the direction of the circumference) of each of the projected parts 174a through 174d may be arranged such that each has a different dimension. Further, the position and angle detection pattern domain 174 is made as large as possible, with least margins at the sides of the player card 20, such that a detection error is suppressed.
As shown in
In the present embodiment, luminosity data Y[n] (at an angle n) of the position and angle detection pattern domain 174 is obtained for every angle in a 1-degree unit, namely, from the angle of 0 degree to 359 degrees, and an edge value is extracted by Edge[n]=V[n−1]−V[n+1]. Here, the forward direction on the play field sheet 80 in view of a game player is defined as the standard angle of 0 degree.
Then, a filter signal (registered beforehand) shown in
When lighting to the player card 20 is not uniform, a detection level of the white part sometimes becomes smaller than the black part, causing distinction from noises difficult. In view of this, the present embodiment evaluates the edge detection value in the direction of the circumference of the projected parts 174a through 174d, where non-uniform lighting to the player card still provides practically uniform brightness in a limited area, enabling to perform a relative process. Accordingly, correct detection of the projected parts 174a through 174d is realized.
Here, an ID decoding process in which an ID data domain 176 and a data domain 180 are read is explained.
When the position coordinates and the angle of the player card 20 are known as mentioned above, bit position of the ID data domain 176 and the data domain 180 is decided uniquely, enabling to perform a distinction process correctly. Further, in the present embodiment, since what is necessary is to carry out a decoding process only to the position coordinates of the detected player card 20, card information can be read in a short time.
As shown in
As shown in
Thus, by making the total of two or more dots as the evaluation value, an adverse influence due to a dot fault or noises can be suppressed. Here, if an accurate evaluation of one dot is available, a value of the dot may be used as the evaluation value.
At this time, the boundary part of the data domain 180 is not used, because the boundary part tends to give an error in detecting the position coordinates and the angle due to a blur at photographing and the like, causing an inaccuracy in calculating the evaluation value.
Similarly, coded patterns 4 through 15, representing 12 bits, are arranged in the ID data domain 176 arranged on the outside of the card position detection circle 172. An evaluation value of the coded patterns 4 through 15 is obtained, and each bit of the card data stored in the player card 20 is obtained. At this time, if the number of difference values between the evaluation values of the white part and the black part of each bit exceeding a threshold value E is larger than a predetermined number, the code is registered as a proper code, and otherwise, the code is deleted as an inaccurate code.
Further, a parity (error detection code) bit is set up and a code that does not agree with the parity bit is also deleted as an inaccurate code. A string of bits that are recognized as correct is decoded according to the ID decoding table (not shown), and the ID data of the player card 20 is obtained. In the present embodiment, two MSBs of the 16 bits are used as parity bits.
Here, an aspect ratio compensation of the image photographed by the image sensor 56 is explained.
Depending on make or model of the image sensor 56, the aspect ratio of a pixel may not be 1:1. In this case, if an image is rotated, the image will be distorted and it will be hard to treat as it is. Therefore, an aspect ratio compensation process is performed. For example, if the aspect ratio of horizontal vs. vertical is 1.29:1, a pixel is expanded 1.29 times vertically so that the aspect ratio of the pixel becomes 1:1.
Next, a lens distortion compensation process of the image sensor 56 is explained.
When there is lens of the image sensor 56 has a distortion (refer to
The standard marker 200 consisting of a black ring as shown in
A Sobel filter is used as the recognition method of the standard marker 200. As shown in
In addition, in the outline extraction process of the standard marker 200, the outline of the standard marker 200 is extracted using the Sobel filter. A position where a total numerical value of the outline values of the standard marker 200 becomes the maximum becomes the coordinates of the standard marker 200. Then, the position coordinates of the play field sheet 80 are compensated by performing pattern matching with the position of the standard marker 200.
As shown in
At S212, a spherical surface compensation filter process for compensating the distortion of the lens of the image sensor 56 is performed. Through the spherical surface compensation filter process, an image from which the distortion, as shown in
Then, at S213, a standard marker position detection process is performed. The standard marker position detection process extracts and recognizes the outline of the standard marker 200 (refer to
At S213b, a pattern matching process is performed for the detection position of the standard marker 200 prepared in the four corners of the play field sheet 80. That is, predetermined standard marker pattern data stored in the database is compared with the detected position of the standard marker 200, such that a difference is obtained. Then, according to the difference, the image photographed by the image sensor 56 is compensated.
At S214, as shown in
At S215, a card angle detection process is performed. As shown in
At S216, an image of luminosity is cut out from the card position coordinates and angle. Then, as shown in
As shown in
In order to detect the card angle, the position and angle detection patterns (white part) 214a through 214d are placed with varied intervals in the direction of the circumference such that edge detection as shown in
Checkered coded patterns 218 formed vertically and horizontally are formed in the ID data domain 216. Each code of the coded patterns 218, that is each of a black part 218a and a white part 218b, occupies about 6 bit×6 bits in the square shape, representing a half-bit (one of the black partial 218a and the white partial 218b). Inside the domain of the half-bit, the color is either all white or all black. In a domain where two coded patterns meet, a bit is always expressed by the combination of the black part 218a and the white part 218b. In this manner, each bit of the coded patterns can be determined from a relative value, i.e., the luminosity difference, even if the determination is impossible from an absolute luminosity value due to uneven lighting and the like.
Further, the coded patterns 170 and 210 may be formed on both sides of the card. In this case, the coded patterns 170 and 210 can be read, regardless of the player card 20 being placed with either side facing up.
As a further variation, each of surfaces of the player card 20 may contain different coded patterns. For example, it is possible to form the coded pattern 170 on the surface of the player card 20, and the coded pattern 210 on the back. In this case, since the coded patterns 170 and 210 are recorded on the different sides of the player card 20, a coded pattern to be read can be switched by placing the card with either side facing up.
Although the embodiments are explained with a soccer game applied to the card game apparatus 10, any other sport games between teams with a plurality of players can be applied.
Further, of course, the card game apparatus 10 is also applicable to an organization game in which two or more individuals participate and perform a joint work for the same objective, other than a sport game.
