TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pachinko gaming machine and a slot machine, and more particularly, to a gaming machine and a gaming method for performing a game using a variable display of identification information.
[0002]
[Prior art]
In a gaming machine such as a pachinko gaming machine, a display device such as a liquid crystal display device (hereinafter, LCD: Liquid Crystal Display) displays predetermined identification information (hereinafter referred to as a display symbol) in an updated manner, thereby performing a variable display. There have been provided a number of games in which a so-called variable display game is used to determine whether or not a predetermined game value is to be given based on the result, thereby enhancing the interest in the game.
[0003]
Some variable display games are played by using the above-described display device as an image display device (hereinafter, a special figure game). In the special figure game, a display symbol is updated and displayed in accordance with detection of a game ball passing through the starting winning opening (variable execution condition is satisfied), and a stop symbol mode when the update display of the display symbol is completely stopped is specified. This is a game in which the display mode is a “big hit”. When a "big hit" occurs in the special map game, a special winning combination or a special electric auditorium called an attacker is opened to continuously provide the player with a state in which it is extremely easy to win a game ball for a certain period of time. This state is referred to as a “specific game state”.
[0004]
The player plays a game with the goal of obtaining this specific game state. Therefore, the player's attention is concentrated on the variable display of the identification information.
[0005]
Various ideas have been applied to the displayed image in order to enhance the interest of the user by changing the display of the identification information in various ways.
[0006]
For the display, a two-dimensional display using a sprite is generally adopted. That is, an arbitrary image is displayed by moving, enlarging / reducing, etc. sprites (two-dimensional images) of various images including identification information on the display screen. In sprite display, it is necessary to prepare an animation pattern for each of a plurality of types of motions, and there is a problem that the required data amount increases as the types of motions increase.
[0007]
On the other hand, a technique has been proposed in which a three-dimensional object is generated in advance using polygons, and thereafter, it is possible to cope with various movements only by changing viewpoints and motion parameters (for example, Patent Document 1). reference).

When the gaming state of the gaming machine 1 is controlled to the probability change state (probability variation state) or the time reduction state, a flag indicating that fact is set in the probability change / time saving flag memory 116. The probable change state is a state in which the probability of a big hit in the special figure game is set higher than usual, and the time reduction state is a state in which the change time of the special symbol in the special figure game is set shorter than usual. . The probable change state and the time reduction state are game states that are more advantageous to the player than the normal game state, and a change pattern with a short change time as illustrated in FIG. 6B is selected.
[0059]
In the big hit flag memory 117, when the gaming state of the gaming machine 1 is controlled to a big hit state, that is, a specific gaming state, a flag indicating that fact is set. The specific game state is set when the combination of the special symbols determined in the special figure game becomes a predetermined big hit combination (for example, the same symbol with a double slot). In the specific game state, the special variable prize ball device 7 is opened until a predetermined period (for example, 29 seconds) or a predetermined number (for example, 10) of winning balls is generated. The game ball falling on the surface is received. Then, on the condition that the received game ball passes through a specific area (not shown) provided in the special variable winning ball device 7 (V winning), the ball is closed and then opened again, and the opening cycle is up to 16 times. Can be repeated times.

The LCD drive circuit 141 converts the image data input from the VDP 136 into a video signal including a color signal and a synchronization signal, and outputs the video signal to the special figure display unit 43.
[0076]
When the display control unit 13 receives the change start command including the information for designating the last stop symbol and the selected change pattern from the game control unit 11, the display control unit 13 changes the special symbol according to the specified change pattern. Then, in the order of the left symbol, the right symbol, and the middle symbol, the fluctuation of the symbol is stopped at the designated final stop symbol, and the final stop symbol is determined.
[0077]
Here, of the operations executed by the display control unit 13, in the present embodiment, a characteristic operation of enhancing the edges of the three-dimensional image and further binarizing to generate a display image is shown in FIG. This will be described with reference to FIGS.
[0078]
First, the VDP 136 reads the wireframe data F1 of the three-dimensional object (the sphere in FIG. 11) from the wireframe memory 138 according to the instruction from the CPU 133, and forms the virtual frame data formed on the RAM 139 as schematically shown in FIG. The wireframe model of the three-dimensional object is arranged at the specified position (x, y, z) in the three-dimensional space (X, Y, Z) (FIG. 11; step S11).
[0079]
Next, an arbitrary symbol (sprite) such as a special symbol designated by the CPU 133 is read from the character ROM 137 and pasted as a texture T on the wireframe model (step S12).
[0080]
Next, an arbitrary symbol such as a special symbol designated by the CPU 133 is read from the character ROM 137, and pasted as a texture of the background image B on the background of the virtual three-dimensional space (step S13).
[0081]
Next, the light source L is arranged at the position designated by the CPU 133 (Step S14).
Subsequently, for each polygon constituting the wireframe model, the brightness of the polygon is obtained, and the value is assigned (applied) to each polygon to perform shading processing (step S15). The method of obtaining the lightness is arbitrary. For example, as schematically shown in FIG. 13, an inner product of a vector Iv indicating the intensity and direction of light emitted from the light source L to the polygon and a unit vector Ev in the normal direction of the processing target polygon are obtained. This can be multiplied by the reflectance R to make R · Iv · Ev lightness.
[0082]
Next, when the image in the three-dimensional space obtained in this manner is viewed from the viewpoint V at the position specified by the CPU 133, the image is obtained by projecting it on the virtual screen S arranged at the position specified by the CPU 133. , R gradation image, G gradation image, and B gradation image are created (step S16).
[0083]
Next, edge enhancement processing is performed on the image data of each of the RGB colors thus obtained (step S17). The method of enhancing the edge is arbitrary. For example, each pixel (pixel) on the image of each color of R (red), G (green), and B (blue) constituting the image projected on the virtual screen S is scanned, and the pixel pij of the i-th row and the j-th column of interest is scanned. , By assigning the lightness M shown in Equation 1.
[0084]
(Equation 1)
Lightness M = ((Δxpij)²+ (Δypij)²)^1/2
Where, Δxpij = mpi (j + 1) -mpij: differentiation of original lightness in x direction
Δypij = mp (i + 1) j-mpij: differentiation of the original lightness in the y direction
mpij: brightness of pixel pij
[0085]
Next, with respect to the brightness imparted to the three-dimensional object in the projection image obtained in this manner, the same shade is applied to an area where the brightness is within a predetermined range, and a process of reducing the number of brightness is performed. In this example, binarization processing for reducing the number of brightness to two is performed, and two-stage shading of light and dark is performed (step S18).
A fixed threshold may be used for the binarization process.
[0086]
Alternatively, a histogram of the lightness (gradation) of the pixels of the binarization target image (RGB) may be obtained, and a threshold value that best separates the respective lightness distributions of the background portion and the graphic portion may be set. Good. In this case, for example, a pixel whose brightness is equal to or less than the threshold T is class 1 (background portion), and a pixel whose brightness is larger than the threshold T is class 2 (graphic portion). Is defined by Expression 2.
[0087]
(Equation 2)
J = Sb / Sw
Where Sb = (N₁N₂) (M₁-M₂)²/ N²
Sw = (N₁σ² ₁) / N + (N₂σ² ₂) / N
Ni: the number of pixels of class i (i = 1, 2)
N: total number of pixels (N₁+ N₂)
mi: Average of density values of class i (i = 1, 2)
σ² _i  : Dispersion of concentration of class i (i = 1, 2)
T = 1,. . . By calculating the value of J for all max, T that maximizes the value of J can be used as the threshold value.
[0088]
Subsequently, using the threshold value T, the brightness of the binarization target image of each of the RGB colors (after the edge enhancement processing) is binarized to obtain a display target image.
[0089]
In order to efficiently perform the binarization process, i) as shown in FIG. 14C, for example, as shown in FIG. Is compared with a threshold value to form a brightness conversion table BT using stored brightness as storage data. Ii) Data (brightness data) of each pixel of the image before conversion shown in FIG. As an address, the brightness conversion table BT is accessed, storage data is read, and an image illustrated in FIG. 14B is formed (the binarization process is performed) using the read value as new brightness data. Is also good.
[0090]
Note that two or more types of brightness conversion tables BT (for example, the one shown in FIG. 14C and the one shown in FIG. 24) may be prepared, and the brightness may be converted by appropriately switching. That is, different types of shadows can be applied. When the brightness conversion table BT2 shown in FIG. 24 is used, a quaternization process is performed. The number of brightness values after the conversion is arbitrary.
[0091]
Subsequently, the image thus obtained is developed together with another two-dimensional image (sprite) at a position on the VRAM 140 designated by the CPU 133 (step S19).
The image obtained by the above-described image processing has an impression that is not so different from the sprite image, and has a high probability of being accepted by the player without discomfort.
[0092]
In this manner, the display control unit 13 can appropriately display the image (sprite) stored in the character ROM 137 in advance and the image appropriately formed by the three-dimensional image processing and display the image without discomfort.
[0093]
The voice control unit 14 and the ramp control unit 15 of FIG. 3 execute the voice output control and the lamp display control independently of the game control unit 11 based on the control command signal transmitted from the game control unit 11. This is the control unit on the sub side.
[0094]
The payout control unit 16 in FIG. 3 controls payout of a game ball, a prize ball, and the like. That is, when the input / output unit 12 detects a winning of a game ball to the ordinary variable winning ball device 6 or the special variable winning ball device 7, the input / output unit 12 detects this and notifies the game control unit 11. In response to this notification, the game control unit 11 instructs the payout control unit 16 to pay out prize balls. The payout control unit 16 pays out a predetermined number of prize balls to the player in response to the instruction. The information output unit 17 is for outputting various game-related information to the outside.
[0095]
Here, the variation of the display symbols displayed on the ordinary figure display unit 41 and the special figure display unit 43, the final display symbols, and the like are uniquely determined according to the control commands output from the game control unit 11. That is, the display control unit 13, the voice control unit 14, and the lamp control unit 15 change the display pattern on the display device 4, output the voice from the speakers 8 </ b> L, 8 </ b> R, and display the blinking of the lamp 9 from the timing of receiving the control command. Are controlled in such a manner that the operations are performed in conjunction with each other.
[0096]
Next, an operation (operation) of the pachinko gaming machine of the present embodiment will be described. First, an outline of a game flow in the pachinko gaming machine of the present embodiment will be described.
[0097]
By operating a handle provided at the lower right position of the pachinko gaming machine 1, a game ball is launched into the game area. The processor 111 of the game control unit 11 monitors the presence or absence of an input of a passing ball detector, a winning ball detector 6c, or the like in the input / output unit 12, and a game ball passes through a passage formed in the passing members 5a to 5d. Upon passing, a random number value is obtained, and this random number value is registered at the head of an empty entry in the ordinary figure holding memory 112 shown in FIG.
[0098]
The game control unit 11 reads the random number value stored in the normal figure holding memory 112 from the first entry, and sets the final display pattern of the normal figure as a winning symbol (（symbol) based on the read random number value. Or a lost symbol (x symbol).
[0099]
The game control unit 11 transmits to the display control unit 13 a display control command for instructing the normal figure display unit 41 to change the display. In accordance with the display control command, the display control unit 13 controls the normal symbol display unit 41, performs a variable display process of alternately lighting the hit symbol and the lost symbol for a certain period, and displays a final symbol. Execute the figure game. The normal symbol is fluctuated for a certain period of time, and if the final display symbol is a hit symbol, the movable wing pieces 6a and 6b of the normal variable winning prize ball device 6 are tilted so as to be enlarged and opened, thereby facilitating winning of the game ball. When a game ball wins in the normal variable winning ball device 6, the winning ball is paid out and the execution condition of the special map game is satisfied.
[0100]
When the game ball wins the normal variable winning ball device 6 (the movable wing pieces 6a and 6b may be in a vertical state or a tilted state), the winning of the game ball is detected by the winning ball detector 6c. Then, the game control unit 11 receives the notification to that effect via the input / output unit 12, generates a random number value, and holds the obtained random number value at the head of an empty entry in the special figure holding memory 113 shown in FIG. Store as information.
[0101]
The game control unit 11 reads the reservation information stored in the first entry of the special drawing reservation memory 113 and executes the special drawing game corresponding to the read reservation information. That is, it is determined from the random number value set in the first entry of the special figure reservation memory 113 whether to make a jackpot or a loss. Further, the combination of the display result of the special symbol (final stop symbol) is determined according to whether the jackpot is a jackpot or a loss.
[0102]
The game control unit 11 selects one of the plurality of variation patterns stored in the variation pattern memory 114 shown in FIG. 5 according to the situation, and acquires the control code. The game control unit 11 transmits, to the display control unit 13, a change start command for instructing a start of the special figure game, a final stop symbol, and a control code for specifying a change pattern. The game control unit 11 measures the elapsed time after the transmission of the fluctuation start command, and transmits a confirmation command when the total fluctuation time has elapsed.
[0103]
The display control unit 13 controls the display device 4 in response to the change start command supplied from the game control board 11 to control the change (variable) display of the special symbol displayed on the special figure display unit 43. Derive the display result.
[0104]
The display control unit 13 changes the video as appropriate according to the time schedule of the fluctuation pattern specified by the fluctuation start command, and changes the three special symbols displayed on the special figure display unit 43.
[0105]
When the display control unit 13 receives the confirmation command from the game control unit 11, it determines the final symbol. If the final stop symbol is a big hit symbol (a state in which three special symbols are aligned) as illustrated in FIGS. 7A and 7C, the gaming machine 1 is in a big hit state (specific gaming state), The opening / closing plate 71 of the special variable winning ball device 7 is opened for a certain time or until a certain number of game balls have won, and the opening and closing are repeated for a certain cycle on condition of V winning. On the other hand, if the final stop symbol is a lost symbol as illustrated in FIGS. 6A to 6C and FIG. 7B, the opening / closing plate 71 of the special variable winning ball device 7 is not opened.
[0106]
The player makes the normal variable prize ball device 6 or the special variable prize ball device 7 win a game ball while performing the normal figure game and the special figure game in this way, and obtains the prize ball paid out by the payout control unit 16. I do.
[0107]
Hereinafter, the processing of the special figure game executed by the game control unit 11 will be described with reference to FIGS.
[0108]
The game control unit 11 starts the special symbol process process shown in the flowchart of FIG. 15 by, for example, a timer interrupt every 2 ms.
[0109]
First, the game control unit 11 detects whether or not a game ball has won the normally variable winning ball device 6 by checking an output of the winning ball detector 6c (step S111). If a game ball has won (step S111; Yes), a winning process is executed (step S112). If no game ball has won (step S111; No), the winning process (step S112) is skipped.
[0110]
In the winning process in step S112, as shown in FIG. 16, it is determined whether or not the number of reservations in the special figure reservation memory 113 is equal to or more than the upper limit value of 4 (step S201). If the number of holds is 4 or more, the special figure game by this winning is invalidated and nothing is performed. On the other hand, if the number of holds is less than the upper limit of 4, the random number program is started and the random number program is started. A numerical value is extracted (step S202). Next, the extracted random number value is set at the head of an empty entry in the special figure reservation memory 113 (step S203).
[0111]
Next, based on the value of the special figure process selection flag stored in the special figure process selection flag memory 115, the game control unit 11 executes any one of the eight processes of steps S100 to S107 shown in FIG. select.
[0112]
The special symbol normal processing of step S100 is processing executed when the value of the special figure processing selection flag set in the special figure processing selection flag memory 115 is the initial value “0”. This process is a process of determining whether or not a special symbol change start condition is satisfied, and updating the special figure process selection flag to “1” if the condition is satisfied. More specifically, as shown in FIG. 17, the game control unit 11 shifts each of the hold information of the second to fourth entries of the special figure hold memory 113 one entry at a time (step S301). Then, after the shift, it is determined whether or not the hold information is stored in the first entry (step S302). If the hold information is stored (step S302; Yes), the timer or the like causes the timer or the like to terminate the immediately preceding special map game. It is determined whether or not a predetermined time has elapsed (step S303). If the predetermined time has elapsed (step S303; Yes), the random number value newly stored in the first entry is read (step S304), and the special figure process is selected. The value of the flag is updated to "1" (step S305). On the other hand, if the hold information is not stored in the first entry (Step S302; No) or if the fixed time has not elapsed since the end of the last special figure game (Step S303; No), the process selection flag is set. This interrupt processing is terminated while maintaining the value of “0” at “0”.
[0113]
The special symbol stop symbol setting process of step S101 is executed when the value of the special symbol process selection flag is “1”, and a process of determining in advance the display result (whether a big hit or not) of the special symbol game and the final stop symbol. It is. In this process, the game control unit 11 determines (predetermines) a display result using the random number value held in the first entry of the special figure reservation memory 113. Specifically, as shown in FIG. 18, a lottery table corresponding to the current gaming state (probable change state, time reduction state, etc. specified by the contents of the probability change / time reduction flag memory 116) is selected (step S401). In step S100 (S304), the random number value read from the first entry of the special figure reservation memory 113 is applied to the selected lottery table, and it is determined in advance (before the special figure game starts) whether or not a big hit has been achieved ( Step S402).
[0114]
In the case of a jackpot (step S403; Yes), a random number value is further extracted to determine a jackpot final stop symbol (step S404). On the other hand, in the case of a loss (step S403; No), the display result of each symbol is determined by extracting a random number or the like (step S405). Thereafter, the value of the special figure processing selection flag is updated to “2” (step S406).
[0115]
The variation pattern setting process in step S102 is a process executed when the value of the special figure process selection flag is “2”. In this process, the game control unit 11 selects a variation pattern used when performing the special figure game from the variation patterns stored in the variation pattern memory 114 shown in FIG.
[0116]
In this variation pattern setting process, as shown in FIG. 19, the game control unit 11 determines whether the probability change flag or the time reduction flag is set in the probability change / time reduction flag memory 116, that is, in the normal figure game and the special figure game. It is determined whether or not the time-saving control process for making the fluctuation time shorter than usual is enabled (step S501). If the probable change flag or the time saving flag is ON (step S501; Yes), one of the time saving variation patterns that can derive the hit or loss set in step S101 is, for example, a random number. Is selected (step S502).
[0117]
On the other hand, when both the probable variable flag and the time saving flag are in the off state (step S501; No), one of the normal fluctuation patterns and one from which the final stop symbol set in step S101 can be derived. Is selected by, for example, generating a random number (step S503).
[0118]
Subsequently, a count value corresponding to the total fluctuation time assigned to the selected fluctuation pattern is set in the special figure fluctuation time timer 118 (step S504).
[0119]
Subsequently, a change start command for instructing a start of the special figure game, a final stop symbol, and a control code for specifying a change pattern is transmitted to the display control unit 13 (step S505). Subsequently, the value of the special figure processing selection flag is updated to “3” (step S506).
[0120]
The change start command transmitted in step S505 is received by the display control unit 13. The display control unit 13 specifies a fluctuation pattern used for the fluctuation display from the information included in the fluctuation start command, and displays the special symbol displayed on the special figure display unit 43 according to the time schedule of the fluctuation pattern. Is changed.
[0121]
This variable display processing will be described with reference to FIGS.
First, the CPU 133 specifies the notified variation pattern (step S601), reads display control data for the variation pattern from the ROM 134, and stores it in the RAM 135 (step S602).
[0122]
The display control data is data for defining a series of display images (as exemplified in FIGS. 6 to 8) to be formed and displayed by the display control unit 13 to realize each variable display. Among them, the display control data for performing the three-dimensional image processing described with reference to FIGS. 12 to 14 includes the timing of performing the processing (elapsed time after the start of the change), the wireframe data to be used, and the texture to be used. (Or its type), the size and position of the wireframe model, the position of the light source, the position of the viewpoint, the position of the screen, the type and position of the background image, and the like are defined. As described above, the display using the three-dimensional image processing is executed, for example, in the middle of the reach effect after the start of the special figure game, or in the scene of the reach announcement / big hit announcement.
[0123]
The CPU 133 starts the fluctuation time timer 133a (step S603). Thus, the processing in response to the change start command ends.
[0124]
The internal interrupt timer 133b of the CPU 133 counts the clock signal output from the oscillation circuit 131. For example, when measuring a time (1/30 second) corresponding to the refresh period of the special figure display unit 43, the internal interrupt timer 133b outputs the internal interrupt signal. appear. The CPU 133 executes the processing of FIG. 21 almost periodically in response to the internal interrupt signal.
[0125]
In the process of FIG. 21, the CPU 133 determines whether or not the count value of the variation time timer 133a is a timing (normal variation display timing) at which a normal variation / effect among special figure variations defined by the variation pattern is performed. Is determined (step S701). In addition, the normal fluctuation display timing is a period during which the display of the fluctuation, stop, production, etc. of the special symbol is performed using the normal sprite image without performing the display for the performance using the three-dimensional image described above. It is.
[0126]
If it is the normal fluctuation display timing (step S701; Yes), the same normal fluctuation display processing as that of the related art is executed (step S602). That is, the CPU 133 notifies the VDP 136 of, for example, information for specifying a special symbol (sprite) to be displayed this time and a display position in order to display a changing special symbol, for example. The VDP 136 expands the image of the designated symbol at a specified position on the VRAM 140.
[0127]
If the timing indicated by the count value of the fluctuation time timer 133a does not match the normal fluctuation display timing (step S701; No), or after the end of step S702, the timing indicated by the count value of the fluctuation time timer 133a becomes It is determined from the display control data whether or not it is time to perform the effect display using the three-dimensional image (step S703). If it is the effect display timing using the three-dimensional image (Step S703; Yes), the three-dimensional image processing described with reference to FIGS.
[0128]
This processing will be described with reference to FIG.
First, based on the display control data, the CPU 133 determines a wireframe model to be used for display, its arrangement position and size, a texture to be pasted on the wireframe model, its position and size, a background image, its position and size, and a light source position. , Etc., and notifies the VDP 136 (step S801). The VDP 136 expands the notified wireframe model in a virtual three-dimensional space formed in the RAM 139, and arranges a light source (step S901). Note that these processes may be omitted when display is performed using a stereoscopic image already developed in the virtual three-dimensional space.
[0129]
Next, the CPU 133 instructs the VDP 136 to generate a display target image by projecting a three-dimensional image in the virtual three-dimensional space onto the virtual screen S (step S802). That is, in the three-dimensional image (wireframe model on which texture mapping has been performed) already developed in the RAM 139, the identification information to be used for display, the position of the viewpoint V, and the position of the virtual screen S are designated to the VDP 136. The VDP 136 forms an image (three RGB components) on the screen S when viewed from the specified viewpoint V for the specified three-dimensional image (step S902).
[0130]
The CPU 133 specifies, for each image, what effect (for example, edge enhancement, binarization, etc.) is to be applied to the three-dimensional image obtained in this way according to the display control data (step S803). If different versions exist for edge enhancement and binarization, the user specifies which version. For example, in order to reduce the brightness, whether to perform a binarization process using the brightness conversion table BT shown in FIG. 14C or a quaternary process using the brightness conversion table BT2 shown in FIG. specify. The VDP 136 performs the specified effect processing (Step S903). For example, for an image for which edge enhancement (boundary enhancement) is specified, edge enhancement processing is performed. For an image for which binarization is specified, the image is binarized based on a predetermined threshold.
[0131]
The CPU 133 specifies the arrangement position, size, and the like of the image thus obtained on the display screen in the VDP 136 (step S804). In addition, a sprite to be displayed on the same screen, and its position and size are designated to the VDP 136. The VDP 136 develops each image on the VRAM 140 according to the instruction (Step S904).
[0132]
In this way, a display image for one frame is formed on the VRAM 140. The CPU 133 performs the above processing and ends the current interrupt processing.
[0133]
The VDP 136 reads out the data developed on the VRAM 140 by the interrupt processing of FIGS. 21 and 22, for example, in a time (1/30 second) corresponding to the refresh period of the special figure display unit 43, and sequentially provides the data to the LCD drive circuit 141. I do. The LCD drive circuit 141 drives the special figure display unit 43 based on the provided image data to display an image.
[0134]
As a result, it is possible to perform a special symbol change display as illustrated in FIGS. 6A to 8B. In particular, it is possible to display an image in which an image generated from a three-dimensional image and subjected to edge enhancement / binarization processing and a two-dimensional image (sprite) stored in the character ROM 137 are mixed.
[0135]
While the display control unit 13 is performing the process described with reference to FIGS. 19 to 21 (special symbol change display process), the game control unit 11 repeats the special symbol change process of step S103 in FIG. Run. This processing is executed when the value of the special figure processing selection flag is “3”. In this process, as shown in FIG. 23, the game control unit 11 subtracts one from the count value of the special figure variable time timer 118 (step S1001). Subsequently, it is determined whether or not the value of the special figure variation time timer 118 is 0, that is, whether or not the special symbol has been varied by the set variation time (step S1002).
[0136]
If it is determined that the special figure variation time timer = 0 (step S1002; Yes), it is the timing when one special figure game has just finished, and the game control unit 11 sets the special figure processing selection flag to “4”. (Step S1003).
[0137]
On the other hand, when it is determined in step S702 that the special figure fluctuation time timer is not 0 (step S1002; No), the current interrupt processing is terminated.
[0138]
The special symbol stop process of step S104 in FIG. 15 is a process executed when the value of the special figure process selection flag is “4”. In this process, the game control unit 11 transmits a confirmation command to the display control unit 13. In addition, in synchronization with the end of the special figure game, each unit that needs to operate is notified of the end of the special figure game. Furthermore, when the final stop symbol corresponds to a hit, the game control unit 11 sets a big hit flag in the big hit flag memory 117, updates the special figure process selection flag to “5”, Updates the special figure processing selection flag to “0”.
[0139]
When the CPU 133 of the display control unit 13 receives the confirmation command sent in the special symbol stop processing of step S104, the CPU 133 performs a display confirmation processing of fixing the variable display to the specified final stop symbol.
[0140]
The special winning opening pre-processing of step S105 in FIG. 15 is processing executed when the value of the special figure processing selection flag is “5”. In this process, the game control unit 11 performs a process for performing an effect before opening the special winning opening 7, for example, a process such as an interval effect before the first opening or between opening processes. When it is time to release the special variable winning ball device 7, the value of the special figure processing selection flag is updated to "6".
[0141]
The special winning opening opening process in step S106 is a process executed when the value of the special figure process selection flag is “6”. In this process, the game control unit 11 performs a process of winning a game ball into the opened special winning opening 7, a process of measuring an opening time, a display control via the display control unit 13, and the like. When the number of winning balls reaches a predetermined number or the opening time reaches a predetermined time, the game control unit 11 updates the value of the special figure processing selection flag. The game control unit 11 counts the number of times the special winning opening 7 is opened for one big hit, and when updating the special figure processing selection flag, if the number of times of opening reaches 16 times, the big hit state is changed. Assuming that the condition for ending is satisfied, the value of the special figure processing selection flag is set to “7”. It is determined whether or not there is (the presence or absence of a V prize). If there is a passing, the special figure processing selection flag is set to “5”, and if there is no passing, it is set to “7”. Thus, in the jackpot state, the opening and closing of the special winning opening 7 is repeated up to 16 times.
[0142]
The jackpot ending process in step S107 in FIG. 15 is a process executed when the value of the special figure process selection flag is “7”, and the game control unit 11 performs a process for ending the big hit state, and executes the special figure process. The value of the selection flag is set to “0”.
[0143]
As described above, according to this embodiment, a three-dimensional image generated by three-dimensional image processing is subjected to binarization processing to impart a relatively flat shading and used for display. An image can be displayed without a sense of incompatibility with the two-dimensional image (sprite). In addition, various display images can be generated by using a three-dimensional image.
[0144]
Furthermore, such effect display may be performed in a situation where the display result at the end of the variable display of the special symbol (identification information) is a specific display result by adjusting the display control data. If this is the case, the player can be given a sense of excitement, and the interest of the game will be improved.
[0145]
In addition, by performing the edge emphasizing process, the edge of the three-dimensional object (brightness boundary) is emphasized, and a display image with less discomfort from sprite display can be obtained.
[0146]
Further, by appropriately selecting an image (multi-gradation) obtained by projecting the image on the virtual screen and an image whose brightness is controlled by the binarization process and using the selected image for display, the processing load is not increased. Thus, various display images can be generated.
[0147]
In addition, by mapping the background texture on the peripheral surface of the virtual space, it is possible to display an appropriate background image while suppressing the burden of controlling the background display.
[0148]
The present invention is not limited to the above embodiment, and various modifications and applications are possible.
[0149]
It should be noted that the image formed as described above may be arbitrarily determined in which scene of the special figure game. For example, by adjusting the display control data, for example, switching between an image with the original brightness obtained by projecting a three-dimensional image on the virtual screen S and an image with a limited number of brightness by the binarization process , The display result of the variable display may be displayed so as to notify that the display result will be a big hit or a reach display. According to this configuration, the display of the effect that gives the player a sense of expectation is diversified, and the interest of the game is improved.
[0150]
For example, in the above-described embodiment, the three-dimensional image is binarized and the lightness (gradation) is set to two levels. However, the number of lightnesses is arbitrary. The brightness number may be obtained. For example, three thresholds may be set and converted into four levels of brightness, or 15 thresholds may be set and converted into 16 levels of brightness.
[0151]
Further, by switching between an image in which the brightness is reduced to n stages and an image in which the brightness is reduced to m stages, it may be notified that the variable display will be in a reach state or a jackpot. In this case, the display control data specifies which brightness conversion table to use, and the CPU 133 notifies the VDP 136 of the brightness conversion table to be used, and the VDP 136 uses the notified brightness conversion table to convert the projection image. Decrease brightness.
[0152]
The numerical values shown in the above embodiment are examples, and can be arbitrarily changed. For example, in the above example, the upper limit of the number of reservations in the special figure reservation memory 113 is 4, but the upper limit of the number of reservations is arbitrary. In addition, the order of stopping symbols that are changing in the special figure game is arbitrary.
[0153]
The method for satisfying the execution condition of the ordinary figure game and the special figure game is not limited to the above embodiment. For example, the prize of a game ball to a specific winning opening is set as an execution condition of the ordinary drawing game, or the passing of a game ball of a specific gate or the winning of a game ball to a specific non-variable winning opening is a special drawing game. It may be an execution condition.
[0154]
Further, in the above-described embodiment, the display control unit 13 includes the CPU 133, the VDP 136, and the like, but the physical configuration is arbitrary. For example, as the CPU 133, a one-chip microprocessor in which the ROM 134 and the RAM 135 are integrated into one chip, or a VDP in which the character ROM 137 and the VRAM 140 are integrated and integrated into one chip may be used. Further, when the VDP has sufficient processing capability by itself, the processing of the CPU 133 described in the above embodiment may be borne by the VDP, and the CPU may not be provided. Conversely, when the CPU is sophisticated, all processing may be performed by the CPU without disposing the VDP.
[0155]
For example, in the above-described embodiment, the game control unit 11 transmits the change start command and the control data (data specifying the jackpot / losing, the final stop symbol, etc.) to the display control unit 13. The data and the data may be transmitted from the game control unit 11 to the display control unit 13 at different timings. For example, a fluctuation start command is transmitted at the stage when the fluctuation start condition is satisfied, and the control data is transmitted at an appropriate timing after the fluctuation execution condition is satisfied, before the start of the fluctuation display, or during a certain period after the start of the fluctuation display. You may make it transmit. For example, 1) the control data is transmitted from the game control unit 11 to the display control unit 13 without waiting for the fluctuation start condition by judging whether or not a big hit occurs at the time of winning the normal variable prize ball device 6; After the conditions are satisfied, the system waits until the fluctuation start conditions are satisfied, scans all the reservation information stored in the special figure reservation memory 113, determines the presence or absence of a notice, a fluctuation pattern, and the like, and determines necessary control data. May be transmitted from the game control unit 11 to the display control unit 13.
[0156]
In the above-described embodiment, the process of reducing the brightness on the display image obtained by projecting the three-dimensional image on the virtual screen S is performed. For example, the brightness itself of each polygon in the virtual space is reduced as shown in FIG. ) Or using the brightness conversion table shown in FIG. 23, and then projecting on the virtual screen. That is, when the VDP 136 performs the processing of step S802 to add lightness to a three-dimensional object in the virtual space, the VDP 136 calculates the original (original) lightness, and subsequently assigns the same lightness to lightness in a predetermined range. , The reduced number of brightness values may be assigned to the three-dimensional object, and an image of the three-dimensional object having the reduced brightness value may be projected on the virtual screen. In this case, a three-dimensional object having the original (original) lightness obtained by the calculation and a three-dimensional object having the reduced lightness may be arranged and used as appropriate for display.
[0157]
The apparatus configuration shown in FIGS. 1 and 2, the block configuration shown in FIGS. 3 and 4, the variation patterns shown in FIGS. 6 to 8, and the configurations of the flowcharts shown in FIGS. 11 and 15 to 22 are arbitrary. Changes and modifications are possible.
