Description

  The present invention relates to a screen display method for performing effect display using a moving image during a game in a display area of a display device provided on a game board surface.

In gaming machines such as pachinko machines and slot machines, various effects are displayed during the game using a display device provided in the gaming board. A liquid crystal panel is often used for this effect display. The liquid crystal panel displays an image with pixels arranged in a matrix.
Display data for displaying an image is generated by the following procedure.
First, the CPU for controlling the effect display receives the display command, analyzes the contents, and determines the contents of the screen to be displayed with reference to schedule data prepared in advance.
Then, a drawing command is output to a VDP (Video Display Processor) based on the schedule data. The VDP expands the drawing command into a bitmap and generates display data in units of pixels and outputs it to the liquid crystal panel.
A circuit for generating display data is usually provided with a buffer for temporarily storing the generated data.

  The drawing command usually takes the form of representing the screen by arranging character data prepared in advance or sprites arranged with a plurality of character data at arbitrary coordinates. In this format, various moving images can be expressed by changing display / non-display of sprites, coordinates, size, and the like. The symbol variation display for displaying the lottery result performed during the game can be expressed by defining each symbol as a sprite and changing its coordinates and the like.

  Patent Literatures 1 and 2 disclose a technique for performing presentation display using a moving image prepared in advance. Patent Document 1 is a technique for displaying a moving image using a low-resolution display panel. Bitmap-like image data representing each frame of a moving image is prepared in advance, and a display program sequentially executes the image. A technique for outputting data is disclosed. Patent Document 2 discloses a technique in which compressed data of a moving image is stored in a ROM, is expanded according to a game state, and is combined with a separately prepared background data or a sprite image and displayed. is doing. In the display process, each decompressed frame data is temporarily stored in the RAM and sequentially used for display.

Since the drawing capability of VDP is limited, the number of sprites that are expressed in 24-bit or 32-bit (hereinafter referred to as “full color”) is limited. Conversely, in order to use a large number of sprites, the color expression is limited to about 256 colors. For this reason, in drawing using sprites, it is difficult to perform high-quality and complicated presentation using a large number of full-color sprites.
When a moving image is used, it is sufficient to sequentially output the moving image data prepared in advance to the display panel, so that full color display can be performed relatively easily. However, since the display can be performed only within the range of the moving image data prepared in advance, it is necessary to prepare a large amount of moving image data in order to realize various presentation displays.

Japanese Unexamined Patent Publication No. 3-55082 Japanese Patent Laid-Open No. 2004-8483

In recent years, it has been proposed that a push button or the like for a user to operate during a game is provided in a gaming machine, and the effect display is changed in accordance with the operation to further enhance the interest.
Such an image can also be realized by, for example, synthesizing a moving image display and a sprite image as disclosed in Patent Document 2. However, if the sprite image is combined without any consideration, an important part of the effect display in the moving image may be covered and the advantage of using the moving image may be impaired. As shown in Patent Document 2, it is possible to avoid such adverse effects by separating the area for displaying the moving image and the area for displaying the sprite image, but the sense of unity as the entire effect display is possible. This leads to another problem of damage.
In view of these problems, the present application aims to realize diversity in which the effect display is changed in accordance with such an operation while performing a high-quality effect display by a full-color moving image display.

The present invention is directed to a gaming machine such as a pachinko machine or a swivel type gaming machine. The gaming machine is provided with a plurality of display panels for effect display during the game. As the display panel, a liquid crystal panel, a plasma display, an organic EL, or the like can be used.
The display panel can be provided on the game board surface and its periphery. For example, if it is a pachinko machine, it can be provided on and around the surface of the board on which the launched game ball flows down, and if it is a rotary-type game machine, it can be provided on the rotating reel and its periphery. One display panel or a plurality of display panels may be provided.
The gaming machine is also provided with an operation unit for the player to operate. As the operation unit, for example, a push button, a lever, a touch panel, or the like can be used. The type, arrangement, and number of operation units are not limited.

The display on the display panel is controlled by a character data storage unit, a screen data storage unit, a drawing control unit, and a display data generation unit. In order to realize the display according to the gaming state, for example, a method of instructing the contents to be displayed by a display command from the main board that controls the entire processing of the gaming machine can be adopted.
The character data storage unit stores in advance the still image data of each frame constituting the moving image to be displayed on the display panel. In addition, character data for displaying sprites may be stored.
In this specification, “character” and “sprite” are used in the following meaning. The sprite means an image displayed as a unit on the screen of the gaming machine. For example, when various persons are displayed on the screen, data for drawing each person is referred to as “sprite”. In order to display a plurality of persons, a plurality of sprites are used. Not only a person but also a house, a mountain, a road and the like constituting a background image can be used as sprites. The entire background image may be a single sprite. The gaming machine can display various images by determining the arrangement of each sprite on the screen and determining the vertical relationship when the sprites overlap.
In a gaming machine, for the convenience of handling data, each sprite is configured by combining a plurality of rectangular regions of a certain size such as 64 pixels vertically and horizontally. Data for drawing this rectangular area is called a “character”. In the case of a small sprite, it can be expressed by one character, and in the case of a relatively large sprite such as a person, for example, it can be expressed by a total of 6 characters arranged in a horizontal 2 × vertical 3, etc. . If the sprite is larger than the background image, it can be expressed using a larger number of characters. The number and arrangement of characters can be arbitrarily specified for each sprite.
If the still image data of each frame described above is also stored in the character data storage unit, it can be regarded as a single image. Therefore, when displaying a moving image on the entire screen, the display panel It can be said that it hits a large sprite of the same size.

  The screen data storage unit stores screen data defining a screen to be displayed on the display panel according to the gaming state by designating still image data in time series. In addition, the screen data may include a drawing command to be output to the display data generation unit depending on the arrangement of sprites. In order to realize the display according to the gaming state, the screen data and the display command from the main board described above may be stored in association with each other.

The drawing control unit outputs a drawing command based on the screen data according to the gaming state. In addition, when a predetermined operation is performed on the operation unit, a drawing command for displaying a predetermined response image on the display panel according to the operation is output.
The display data generation unit refers to the character data storage unit according to the drawing command and generates display data for effect display.
However, in the present invention, when the operation unit is operated, the drawing control unit determines whether or not to display the response image and at least one of the display modes based on the still image data to be displayed on the display panel. Based on the determination, a drawing command for displaying the response image is output.

According to the present invention, since still image data obtained by dividing a moving image into frames is used, a full-color moving image can be displayed. Since still image data can be handled in the same way as sprites, it is relatively easy to synthesize response images according to user operations in the same way as when displaying various sprites. Can be output.
Since the still image data to be displayed can be specified at the time when the operation is performed, it is possible to determine whether or not there is a possibility that the response image may cover the still image data inappropriately and impair the interest. Therefore, it is possible to display the response image only when there is no such a risk, or to control the display position and size of the response image so as to alleviate the risk. By doing so, it is possible to display various images according to the user's operation while performing high-quality effect display using a full-color moving image.

Display control such as whether or not to display the response image and the display mode can be realized by various methods.
For example, control data for controlling display of a response image with respect to still image data may be included in the screen data. As the control data, a flag indicating whether or not the response image can be displayed, coordinate value data indicating a displayable area, and the like can be used. By doing so, the drawing control unit can make a determination regarding the display of the response image based on the control data.
As another aspect, the character data storage unit may store the above-described control data in association with the still image data. In this way, if the drawing control unit refers to the character data, it is possible to make a determination regarding the display of the response image.

As a result of the above determination, if it is determined that the response image cannot be displayed, the drawing command output is suspended, and the drawing command is determined when it is determined that the response image can be displayed based on still image data from the next time. May be output.
In this way, even when the response image cannot be displayed at the time when the operation is performed, it is possible to display the response image within a slightly delayed screen.
However, it is preferable to suppress the delay until the response image is displayed to such an extent that the user does not feel uncomfortable. From this point of view, when it is determined that the response image cannot be displayed, an upper limit may be provided for the period during which the drawing command output is suspended.

The effect display of the present invention may include a symbol variation display as a moving image display until the result of the lottery executed by the gaming machine at a predetermined timing is displayed. It is only necessary to prepare moving images for realizing a plurality of types of symbol variation display in which the symbol variation pattern is changed for each lottery result, and to generate still image data corresponding to each. In this case, it is preferable that the moving image display and the still image data are data that can be displayed in a size that can be displayed on the full screen, that is, the same size or larger as the display panel. By doing so, it is possible to realize an expressive presentation using the entire screen without a sense of incongruity.
And, by making the command indicating the gaming state into a form that can also specify the type of symbol variation display, that is, the lottery result and the symbol variation pattern, the drawing control unit identifies the still image data corresponding to this command, The display control described above can be executed. When full-screen display is performed, this display control is performed by outputting a drawing command for sequentially drawing still image data at a fixed size and coordinate position. The constant size means that the drawing size is constant. For example, a method may be employed in which the generated display data is enlarged at a certain enlargement ratio while being drawn at a certain size smaller than that of the display panel.
By doing so, it is possible to apply various screen displays according to user operations while using full-color moving images in the symbol variation display, which is an effect display that is important for enhancing interest in gaming machines.

  In the present invention, it is not necessary to have all the various features described above, and some of them may be omitted, or may be applied in combination as appropriate. In addition, the above-described characteristic portion in the present invention may be realized by hardware or software.

A. Game machine configuration:
FIG. 1 is a front view of a pachinko machine 1 as an embodiment. The pachinko machine 1 has a game board having a game area 6 in the center. The player can play a game by operating the handle 8 and driving a game ball into the game area 6 to win a winning opening. When a game ball wins a start winning opening which is one of the winning openings, the pachinko machine 1 draws a lottery, and it is determined whether or not it is a “hit” according to the result. In the figure, as a result of the lottery, “777” is aligned and a big hit is shown. When a big hit occurs, a big hit game such as a special winning opening being opened for a predetermined period is performed.

  In the center of the game area 6, an LCD 16 is provided, and various effect screens (sometimes referred to as decorative symbols) depending on the game state, such as when winning at the start winning opening or when a big hit occurs. Is displayed. For example, at the time of winning a winning prize opening, first, a symbol change display for changing a symbol such as “777” shown in the drawing is performed, then the symbol is stopped, and a series of effect displays showing the lottery results are performed. As a display panel for performing these effect displays, an organic EL, LED, plasma display, or the like may be used instead of the LC 16.

  In the gaming machine 1, three push buttons 9 are provided on an upper plate portion in which game balls accumulate. When the player presses the push button 9 when the symbol variation is displayed, the variation of the symbol can be stopped or the variation state such as the variation speed can be changed.

B. Control hardware configuration:
FIG. 2 is a block diagram showing a control hardware configuration of the pachinko machine 1. The pachinko machine 1 is controlled by distributed processing of each control board such as the main control board 3, the payout control board 25, the sub control board 35, and the decorative design control board 30. The main control board 3, the payout control board 25, and the sub control board 35 are each configured as a microcomputer having a CPU, a RAM, a ROM, and the like, and implement various control processes according to programs recorded in the ROM. . In this embodiment, the sub-control board 35 and the decorative design control board 30 are configured as separate boards, but may be a board in which both are integrated. In this case, the function of the sub-control board 35 and the function of the decorative design control board 30 may be realized by distributed processing of a plurality of CPUs or may be realized by a single CPU.

In the pachinko machine 1 according to the embodiment, input from the outside to the main control board 3 is restricted in order to prevent various frauds. The main control board 3 and the sub control board 35 are connected by a unidirectional parallel electric signal, and the main control board 3 and the payout control board 25 are connected by a bi-directional serial electric signal for the necessity of control processing. Yes. The payout control board 25 and the sub control board 35 operate in response to commands from the main control board 3, respectively. The decorative design control board 30 operates in response to a command from the sub control board 35.
The pachinko machine 1 also has a mechanism that is directly controlled by the main control board 3. In the figure, as an example of a device controlled by the main control board 3, a special winning opening solenoid 18 for driving a special winning opening and a special symbol display device 41 are illustrated. In addition to this, the main control board 3 can control displays such as a normal symbol display device, a special symbol hold lamp, a normal symbol hold lamp, a big hit type display lamp, and a status display lamp.
Further, detection signals from various sensors are input to the main control board 3 in order to control the operation during the game. In the figure, the input from the winning detector 15a is illustrated as an example. The winning detector 15a is a sensor for detecting a winning at the start winning opening. The main control board 3 can execute the jackpot game by performing the lottery described above according to the signal from the winning detector 15a. Various other inputs are made on the main control board 3, but the description thereof is omitted here.

  Other controls during the game are performed via the payout control board 25 and the sub-control board 35. The payout control board 25 controls the launch and payout of the game ball being played in the following procedure. The launch of the game ball is directly controlled by the launch control board 47. That is, when the player operates the handle 8, the launch control board 47 controls the launch motor 49 according to the operation to launch a game ball. The game ball is fired only under a situation where the touch detector 48 detects that the player is touching the handle 8. The payout control board 25 indirectly controls the launch of the sphere by sending a launch control signal to the launch control board 47.

  When a command indicating that a prize has been won during the game is received from the main control board 3, the payout control board 25 controls the payout motor 20 in the prize ball payout device 21 and regulates the number of balls by the payout ball detector 22. Pay out a number of balls. The operation of the payout motor 20 is monitored by a motor drive sensor 24, and when an abnormality such as a ball bit or a ball break is detected, the payout control board 25 displays an error code on the display unit 4a. When an error is displayed, it can be recovered by operating the operation switch 4b after the attendant has removed the abnormality.

  The sub-control board 35 controls effects such as voice, display, and lamp lighting during the game. These effects vary according to the status during the game, such as a normal time, a prize, a big win, an error, an alarm when an illegal act or other abnormality occurs. The push button 9 is connected to the sub control board 35, and the sub control board 35 changes the content of the effect display according to the operation state. When an effect command corresponding to each status is transmitted from the main control board 3, the sub control board 35 activates a program corresponding to each command to realize the effect instructed from the main control board 3. .

  In the present embodiment, the sub-control board 35 directly controls the speaker 29 as shown in the figure. The LCD 16 is controlled via the decorative design control board 30. The circuit configuration of the decorative design control board 30 will be described later. The lamps to be controlled by the sub-control board 35 include the panel decoration lamp 12 provided on the game board surface and the frame decoration lamp 31 provided on the frame. The sub control board 35 is connected to the panel decoration lamp 12 and the frame decoration lamp 31 via the lamp relay boards 32 and 34, and can blink each lamp individually.

  FIG. 3 is an explanatory diagram showing a circuit configuration of the decorative design control board 30. The decorative design control board 30 outputs display data for displaying a screen on the LCD 16 in accordance with the display command received from the sub control board 35. The display data is data indicating display gradation values of the R, G, and B pixels provided on the LCD 16 in a matrix.

The decorative design control board 30 is provided with various circuits shown in the drawing in order to realize a function of generating display data.
First, the decorative design control board 30 is provided with a CPU 381, a RAM 382, and a ROM 383 as microcomputers for controlling the generation of display data.
The ROM 383 stores a display program for generating display data, a screen to be displayed in response to a display command, a scheduler for defining a display time, a display order, and screen data for defining each screen configuration of the LCD 16. . The contents of the screen data will be described later, but at this stage, the data does not correspond to the pixels of the display panel.
The CPU 381 refers to the ROM 383, extracts screen data corresponding to the display command, and outputs it to a VDP (Video Display Processor) 385 as a drawing command.

The character ROM 386 stores sprite data, that is, data representing a sprite displayed on the screen as a bitmap. A sprite is a collection of character data having a rectangular area of 64 dots × 64 dots as a unit. The number of character data constituting the sprite is variable depending on the size of the sprite.
The sprites of this embodiment can be roughly classified into two types.
The first is the storage of still image data (hereinafter, also referred to as “frame image”) of each frame constituting a moving image as sprites. This still image data is data expressed in full color like a moving image. In the case of using a moving image for presentation display, a method of storing moving image data compressed in MPEG format or the like in the character ROM 386 and expanding and displaying it appropriately is often used. In this embodiment, It is assumed that still image data that has been divided in advance in units of frames is stored in the character ROM 386. The advantages of adopting this aspect will be described later.
The second is a sprite expressed in 256 colors. In the present embodiment, it is used to display a screen when a moving image is not used or to display various images combined with a moving image. In this embodiment, since the composition with the moving image is performed when the push button 9 (see FIG. 1) is operated, the image displayed on the sprite is hereinafter referred to as a response image in order to be composed with the moving image. Sometimes called.

  As described above, the character ROM 386 requires an enormous storage capacity in order to store still image data constituting a moving image. In the present embodiment, a NAND flash memory 386N is used as the character ROM 386 in order to meet such a demand. As is well known, the NAND flash memory 386N is more suitable for increasing the degree of integration and increasing the capacity than the NOR flash memory, and has an advantage that reading at a high speed is possible. As will be described later, the character ROM 386 is a memory that is accessed many times when the VDP 385 generates display data. Therefore, the large capacity and high-speed reading characteristics of the NAND flash memory 386N are suitable for use as the character ROM 386. -ing

However, the NAND flash memory 386N has a disadvantage in that there are not a few blocks having a defective function as a memory, so-called bad blocks. Such bad blocks may be newly generated even during use. In order to cope with such an adverse effect, in this embodiment, the controller 386C of the NAND flash memory 386N is provided in the character ROM 386. The controller 386C is a circuit having a function of mutually converting the logical address of the character ROM 386 and the physical address of the NAND flash memory 386N. In other words, the controller 386C holds a management table that represents the correspondence between the usable blocks excluding the bad block among the blocks of the NAND flash memory 386N and the above-described logical address. Based on this management table, The logical address and the physical address are converted. Therefore, for example, if the VDP 385 is a logical address and the character ROM 386 requests predetermined sprite data, the controller 386C converts the logical address to a physical address based on the management table, and is requested from the NAND flash memory 386N. Data can be read out.
In the present embodiment, the character ROM 386 capable of high-capacity and high-speed reading is configured by using the NAND flash memory 386N and the controller 386C in this way, but the character ROM 386 is configured using a NOR flash memory. It is also possible to do.

  The VDP 385 extracts sprite data to be displayed from the character ROM 386 based on the screen data received from the CPU 381, generates display data, that is, data obtained by developing a bitmap of the image to be displayed, and outputs the generated data to the panel interface 390. . This process is performed at a cycle of 16 msec. The same applies to the display data output to the LCD 16. The VDP 385 also outputs a synchronization signal suitable for this cycle together with the display data, and this synchronization signal is used as it is for driving the LDD 16.

  A virtual storage area of the VDP 385 for developing a bitmap is called a “canvas”. When displaying only a moving image on the LCD 16, the VDP 385 sequentially reads out sprites representing still image data in units of frames, expands them almost as they are on a canvas, and outputs them as display data. When a moving image is not used, a plurality of 256-color sprites are read from the character ROM 386 and arranged on the canvas at the position specified by the drawing command to generate display data. When combining and outputting a moving image and a response image, a sprite representing still image data is expanded on the canvas, and a sprite corresponding to the response image is further expanded on the canvas to generate display data. This composition may be performed by, for example, a method of overwriting the pixel corresponding to the response image after expanding the still image data, or another layer that is displayed with priority over the layer that expands the still image data. A method of developing the response image may be employed.

The VDP 385 includes a sprite register 385s and a VDP register 385v as registers for receiving and holding screen data from the CPU 381.
The sprite register 385s is a register for receiving drawing commands indicating the arrangement of sprites and the order of superposition among screen data, and is configured as a double buffer. That is, two buffers having the same capacity, that is, a first buffer and a second buffer are provided. Therefore, while the drawing command output from the CPU 381 is written in the first buffer, the VDP 385 can read the drawing command held in the second buffer and execute display data generation processing.
The VDP register 385v is a register for storing a command (hereinafter referred to as a “condition setting command”) that specifies a condition setting when generating display data. The condition setting command includes, for example, the overlay order of each layer, display / non-display setting, etc., when the drawing command is composed of a plurality of layers. Since the condition setting command has a relatively low capacity and the time required for writing is short, the VDP register 385v is not a double buffer.

The frame memory 397 is a buffer for storing display data, and is divided into two areas of fields 397 [0] and 397 [1]. These fields function as a double buffer. For example, while the display data newly generated by the VDP 385 is being written in the field 397 [0], the display data already stored is read from the field 397 [1] and output to the LCD 16. When the writing to the field 397 [0] is completed, the panel interface 390 switches the writing / reading mode of each field, outputs the front side data from the field 397 [0] to the LCD 16, and newly generated display data. Is written in the field 397 [1]. This switching is performed according to a field signal output from the CPU 381.
The panel interface 390 may be capable of enlarging or reducing the size of the display data so as to match the number of pixels of the display panel when the display data is stored in or read from the frame memory 397. For example, when the drawing capability of the VDP 385 is insufficient for the resolution of the LCD 16, the display data is generated at a low resolution within the drawing capability of the VDP 385, and the enlargement process is performed by the panel interface 390 so as to match the resolution of the LCD 16. Just do it.

C. Screen display example:
C1. Symbolic change display by animation:
FIG. 4 is an explanatory diagram showing a screen display example (1) of the LCD 16. FIG. 4A to FIG. 4F show the state of symbol variation display. This symbol variation is generated by a moving image.
In this embodiment, as shown in FIG. 4 (a), a symbol indicating a Chinese numeral is used at the center of the fan. As shown in FIG. 4B, the symbol variation starts as the symbol collapses into fine pieces. As the piece collapses, the highlight behind the symbol shines white as shown in FIG. 4 (c). As shown in FIG. 4 (d), a fan representing the next symbol out of the light is displayed. appear.
Thereafter, as shown in FIG. 4 (e), the fan gradually increases so as to fly in the air, and a design appears on the fan as shown in FIG. 4 (f). Eventually, as shown in FIG. 4 (a), the symbol is clearly displayed and stops.

In the present embodiment, since the symbol variation is prepared in advance as a series of moving images, it is possible to perform display with various characteristics shown below.
First, display that fully utilizes the full-color gradation, such as using the gradation used in moving images, that is, a full-color design, and using highlights (Fig. 4 (c), Fig. 4 (d)) during the fluctuation. Is possible. Also, as shown in FIG. 4 (b), since the symbols are displayed in a shape that collapses into pieces, various expressions that cannot be expressed simply by moving, inverting, enlarging or reducing the sprite representing the symbols are performed. Is possible.
However, it is necessary to prepare in advance moving images corresponding to all combinations of numbers at the start of symbol variation and numbers at the time of stop. In FIG. 4, the symbol variation display starting from “six” is illustrated, but similar moving images starting from other numbers must be prepared separately. Also for the variable display starting from “6”, it is necessary to prepare a different moving image for each number at the time of stoppage.

FIG. 5 is an explanatory diagram showing a display example of a response image. The response image is an image that is displayed in response to the operation of the push button 9 (see FIG. 1) by the player. In the figure, an example is shown in which a response image RP is displayed over the symbol LP currently being displayed.
The timing at which the response image is displayed and the meaning of the response image can be arbitrarily set by the gaming machine.
For example, there is no particular influence on the game, and it is displayed only for the purpose of enhancing the interest of the game effect display as a so-called premium image displayed only when the push button 9 is operated under a predetermined condition. May be.
Moreover, it is good also as what is called a jackpot notice display. The notice display is a display indicating that the timing when the push button 9 is pressed is a big hit without waiting for the display of the lottery result when a predetermined condition is satisfied. By this display, the player can be prepared in advance for the big hit game to come and can enhance the interest of the game. Similarly, when the push button 9 is pressed at a predetermined timing, a probability fluctuation that increases the probability that a jackpot will be generated may be generated, and this may be notified by a response image. In this embodiment, the main control board 3 and the sub control board 35 are connected by a unidirectional signal line, and communication from the sub control board 35 to the main control board 3 is prohibited. In order to provide a function that affects the game itself, such as causing fluctuations, it is preferable that the operation state of the push button 9 can be detected by the main control board 3. In this case, a command indicating the operation state of the push button 9 may be transmitted from the main control board 3 to the sub control board 35 to reflect the operation state on the effect display. The operation state may be separately detected by the sub-control board 35.

Thus, although it is a response image which can be used for various purposes, if it is displayed at an inappropriate timing, there may be a case where the effect intended in the symbol variation display is impaired.
For example, at the timing shown in FIG. 5, the fan design LP displayed in the center is covered with the response image RP. When the player is in an attitude that cannot see the Chinese numerals written on the fan's design LP, when this design LP is displayed, even if the response image RP is displayed, there is no significant effect. If the response image RP is displayed when the number is visible, the player's sense of expectation may be greatly impaired by the Chinese number.
Whether the intention of the moving image is impaired depends on the use of the response image. For example, in the case of a jackpot notice display, even if it is displayed so as to cover the Chinese numerals, it is considered that the influence on the player is small.
As described above, it is preferable to display the response image in consideration of the production intention by the moving image displayed behind the response image. In this embodiment, the response image is not displayed unconditionally in response to the operation of the push button 9, but the response image can be displayed, the display position, the display size, etc. in consideration of such influence by the control processing described later. To control.

C2. Symbol variation display by sprite:
FIG. 6 is an explanatory diagram showing an example of symbol variation display by sprites. In this example, an example is shown in which symbol variation display is performed by combining 256 color sprites. In the present embodiment, depending on the gaming state, it is used separately from the symbol variation display by the moving picture shown in FIG. In the example of FIG. 6, as shown in FIG. 6A, a guidance “Press the button” is displayed along with the slot screen. On the slot screen, a symbol is rotated and displayed in the direction indicated by the arrow A like a rotating reel. When the player presses the push button 9 (see FIG. 1), the symbols are stopped in various combinations as shown in FIGS. 6B and 6C according to the timing.
As shown in FIG. 6C, these symbol variation displays are configured by combining a sprite SP1 indicating a slot frame and a sprite SP2 having a symbol shown in the slot. Various fluctuating states are displayed by changing the type of sprite SP2 or changing the position. Unlike the case of using a moving image, this method cannot produce various effects using full color, but it is not necessary to prepare moving image data corresponding to a variable display pattern in advance. There is an advantage that a variable display can be realized.

  In the symbol variation display by the sprite, the reverse display shown in FIG. 6D can also be performed. In this example, when the player repeatedly presses the push button 9, the rotation of the slot is slowed according to the frequency of pressing, and when the player repeatedly presses the push button 9 repeatedly, the slot can be reversed as indicated by an arrow B. By doing so, it is possible to make the player who wants to win a jackpot push the push button 9 crazy and to enhance the interest. In this example, since the variable display by the combination of sprites is used, the reverse display is easily realized by gradually moving the position of the sprite SP2 upward according to the operation frequency of the push button 9. Is possible.

D. Frame image generation:
FIG. 7 is an explanatory diagram showing the structure of the frame image generation apparatus 500. The frame image generation apparatus 500 is prepared separately from the gaming machine, generates a moving image for performing the symbol variation display shown in FIG. 4 in accordance with an instruction from the operator, and based on this, generates a still image for each frame. It has a function of generating and outputting data, that is, a frame image. By storing the generated frame image in the character ROM 386, it is possible to display a moving image intended by the operator on the LCD 16 of the gaming machine.
The illustrated functional blocks can be constructed in software by installing a computer program for realizing these functions in, for example, a general-purpose personal computer. You may build in hardware.

The input unit 510 inputs an instruction from an operator through operation of an input device such as a keyboard and a mouse. This instruction includes, for example, designation of a lottery result and a variation pattern. This is a designation of what variation pattern is used to generate a moving image indicating a combination of symbols when the variation is stopped.
The moving image editor 520 generates a moving image according to this instruction. The image data that is the material of the pattern such as the fan and number shown in FIG. 4 may be generated each time according to an instruction from the operator, or a database in which these materials are stored in advance is prepared. You may make it acquire suitably from a database.

The generated moving image is temporarily stored in the moving image library 530. At this point, it is a compressed moving image file such as MPEG format. The playback unit 540 can decode the moving image file and display it on the display 501 of the computer. The operator can check the image and input an instruction again as necessary to correct the moving image file.
As described above, in this embodiment, frame images are stored in advance in the character ROM 386 for all combinations of lottery results and variation patterns. Therefore, the operator sequentially generates moving image files while changing the lottery result and the condition of the variation pattern so as to correspond to all these combinations. In the moving image library 530, a plurality of moving image files corresponding to all these combinations are accumulated.

  The frame dividing unit 550 decodes the moving image file stored in the moving image library 530 and generates still image data of each frame. The still image data is stored in the frame image library 560 after being associated in order as a frame image group generated from one moving image file. The association can be performed, for example, by a method of preparing a management file in which the storage addresses of the respective frame images are sequentially recorded according to the frame order of the moving images, separately from the frame images. Alternatively, a method of sequentially storing a series of frame images at consecutive addresses in the frame image library 560 may be used. In this aspect, for example, information indicating the size of each frame image and the number of frame images constituting the moving image may be stored as a header when the first frame image is stored.

  The schedule data generation unit 570 generates schedule data for associating frame images. The schedule data is data used by the CPU 381 to output a drawing command for generating display data based on the frame image to the VDP 385. Although it is one of the screen data in terms of data defining the display content of the LCD 16, in this embodiment, unless otherwise specified, the term schedule data is used in a limited sense as data defining the generation order of moving images. Shall. Although the data structure of the schedule data will be described later, it is data for sequentially specifying the storage address of each frame image when reproducing a moving image. When the frame dividing unit 550 generates the above-described management file when associating each frame image, the management file can be used as schedule data.

  In the present embodiment, the schedule data generation unit 570 further performs processing for avoiding duplication of frame images. In other words, since the same scene may be included in a plurality of moving image files, there may be images that overlap between different moving images in the frame images generated by dividing each moving image file into frames. is there. The schedule data generation unit 570 also has a function of generating schedule data so that a single frame image can be shared by these moving images when the frame images overlap in this manner among a plurality of moving images. ing.

FIG. 8 is a flowchart of the schedule data generation process. The process which the schedule data generation part 570 (refer FIG. 7) performs is shown in the form of the flowchart. The schedule data generation unit 570 first reads a frame image group constituting a moving image to be processed from the frame image library 560 (step S10). Then, schedule data as an initial state is set (step S11). The schedule data at this point may be any data that specifies the frame images constituting the moving image to be processed in the playback order.
Next, the schedule data generation unit 570 matches the frame image group of the moving image to be processed with the already processed frame image group (step S12), deletes the matched frame image, and corrects the schedule data. (Step S13).
The schedule data generation unit 570 repeatedly executes the above processing for all moving images (step S14), and outputs a frame image and schedule data (step S15).

The state of schedule data generation is shown schematically on the right side of the figure. In the following description, it is assumed that the moving image B is processed when the moving image A has already been processed.
On the upper side, schedule data and frame images in the initial state are shown for moving picture A and moving picture B. The moving image A is composed of frame images Fa1, Fa2, Fa3, and Fa4, and the schedule data SDa is data indicating the reproduction order as “Fa1 → Fa2 → Fa3 → Fa4”. The moving image B is composed of frame images Fb1, Fb2, Fb3, and Fb4, and the schedule data SDb is data indicating the reproduction order as “Fb1 → Fb2 → Fb3 → Fb4”.

  In this state, the schedule data generation unit 570 performs matching between the moving image B and the already processed moving image A. As illustrated, it is assumed that the frame images Fb1 and Fb2 are the same as the frame images Fa1 and Fa2, respectively. This matching can be performed in various ways. For example, there is a method in which the difference between the gradation values of the respective pixels of the frame images Fa1 and Fb1 is obtained, and when the sum of the absolute values is equal to or less than a predetermined value, it is determined that they match. The frame image Fb1 may be matched with all the frame images Fa1, Fa2, Fa3, and Fa4 of the moving image A, but in this embodiment, only the frame images at the same reproduction position (for example, the first frame image Fb1) And Fa1) are matched. This is because in a gaming machine, a moving image is generated with a predetermined variation pattern, so matching images often appear at the same playback position.

The lower side shows a state where the matched frame is deleted. As described above, the frame images Fb1 and Fb2 that overlap the frame images Fa1 and Fa2 are deleted. In response to this, the schedule data SDb2 of the moving image B is corrected as “Fa1 → Fa2 → Fb3 → Fb4”. By doing so, the capacity of the frame image can be suppressed by the amount of the frame images Fb1 and Fb2.
However, matching of frame images and correction of schedule data are not essential processes, and may be omitted.

E. Screen data structure:
FIG. 9 is an explanatory diagram showing the structure of screen data. As shown on the left side, the screen data SD is data that defines the sprites that constitute the frame for each of the frames [1], [2]... Of the series of images to be displayed on the LCD 16. . In the example shown in the figure, the frame [1] is configured by sprites [11], sprites [12], and the like, and the frame [2] is configured by sprites [21], sprites [22], and the like. In this embodiment, since frame images representing moving images (see FIGS. 7 and 7) are also handled as sprites, in the screen data SD when displaying moving images on the LCD 16, that is, schedule data, a single sprite is assigned to each frame. It will be specified.

  In the center of the figure, setting information SPL for each sprite is shown. The setting information SPL may be prepared by being incorporated in the screen data SD, or may be prepared as separate data. In the latter case, the screen data SD and the setting information SPL may be associated with each other so that the storage address of the setting information SPL for the sprite is recorded in the sprite [11] of the screen data SD.

The contents of the sprite setting information SPL are as follows.
“Character number” indicates the head address where the sprite is stored in the character ROM 386, and “Size” indicates the horizontal and vertical sizes of the sprite. As described above, since the sprite is stored in the character ROM 386 as a collection of 64 dot × 64 dot character data, in this embodiment, “size” is designated by the number of character data in the vertical and horizontal directions. It was supposed to be.
The memory structure of the character ROM 386 is schematically shown on the right side of the figure. Addresses AD [0] to AD [n + 1] each represent a memory area storing character data. Here, consider a case where a sprite is stored at addresses AD [0] to AD [n]. At this time, the address AD [0] which is the head address is stored in the character number, and the number of vertical and horizontal character data is stored in the size so as to correspond to the addresses AD [0] to AD [n]. Will be. For another sprite, the address AD [n + 1] is stored in the character number.
In the present embodiment, when frame images constituting a moving image are stored in the character ROM 386 as sprites, the size of each frame image is uniform and a constant value can be used. In such a case, in the case of a sprite constituting a moving image, it is possible to omit the size designation from the setting information SPL. For example, as for “size”, the previous designation may be applied as it is unless it is newly designated. In this way, in the screen data SD representing the moving image, it is possible to omit the subsequent “size” designation only by designating “size” in the first sprite setting information SPL.

  “Color format designation” is information indicating whether the sprite is 256 colors or full color. In this embodiment, since only two types of formats are used, a “bit format specification” may be a 1-bit flag. When the sprite has 256 colors, a color palette that associates color numbers with display colors is prepared separately. In this embodiment, a plurality of types of color palettes can be used properly. The color palette to be used for displaying the sprite can be designated by “color palette number”.

“Display end” and “display skip” are information used in display data generation processing in the VDP 386, respectively. In this embodiment, the VDP 386 is configured to execute drawing processing for all sprites in order from the smallest character number. If “display skip” in the setting information is set to “non-display” for a sprite that is not specified by the screen data SD, the VDP 386 does not draw the sprite and performs processing for the next sprite. Transition. If the “display end” setting information is set to “end”, the VDP 386 ends display data generation for the subsequent sprites without performing drawing processing.
For example, in the screen data SD in the figure, when the processing of frame [1] is performed, “non-display” may be set for “display skip” such as sprites [21] and [22]. Even if the VDP 386 processes the sprites [11], [12], etc., and starts the processing for the sprites [21], [22], these sprites are set to “non-display”. The process is terminated without drawing. Instead of this setting, for example, “end” may be set in “display end” of sprite [12]. In this case, the VDP 386 determines that there is no need to process the subsequent sprites [21], [22], etc. when the processing of the sprite [12] is completed, and ends the generation of display data. . As described above, “display end” and “display skip” are information for controlling the execution range of the display data generation processing in the VDP 386.

“Coordinates”, “magnification ratio”, and “inversion” are information for controlling the display mode of the sprite. “Coordinates” are coordinates at which sprites should be arranged on the canvas. The “magnification ratio” is a magnification when displaying a sprite. “Inverted” is information indicating whether or not to display the sprite in a horizontally inverted or vertically inverted manner. In addition, information indicating the “rotation” of the sprite may be designated.
When frame images that display moving images on the entire screen are stored in the character ROM 386 as sprites, the arrangement of the frame images is uniform, and a constant value can be used. The enlargement ratio and the presence or absence of inversion are also constant. In such a case, in the case of a sprite constituting a moving image, at least a part of the coordinates, the enlargement ratio, and the inversion may be omitted from the setting information SPL as in the case of size designation.

The “response image display area” is information indicating an area that can be displayed by superimposing another sprite on the sprite. Depending on the sprite, there may be an important part that you want to avoid overlapping with other sprites. In such a case, the area excluding this important part may be set as the “response image display area”. The response image display area can be specified by various methods. For example, a method may be used in which a point sequence of polygon vertices corresponding to an area where other sprites can be displayed or a display prohibited area is indicated by coordinate values. In addition, a flag indicating whether or not the response image can be displayed may be designated in units of character data constituting the sprite. When it is prohibited to display other sprites in a superimposed manner, the entire sprite may be set as a display prohibited area. However, in addition to the “response image display area”, a method of providing a flag indicating whether or not other sprites can be displayed may be employed.
The “response image display area” is useful information particularly in the case of a frame image. In the present embodiment, as shown in FIG. 4, a frame image is generated based on a moving image displayed on the entire screen of the LCD 16. Therefore, unlike 256-color sprites prepared on the premise that a screen is configured by combining a plurality of sprites in advance, the CPU 381 of the decorative design control board 30 determines the contents of the screen only with a frame image. I can't. As a result, depending on the frame image, another sprite may be displayed in an important part, and the intended effect may be impaired. In this embodiment, by setting the “response image display area”, even if the CPU 381 cannot determine the contents of the screen, it is possible to easily avoid such an adverse effect.

F. Display control processing:
F1. Overall processing:
FIG. 10 is a flowchart of the display control process. This is a process executed by the CPU 381 to output a drawing command or the like to the VDP 385 and generate display data. This process is executed as an interrupt process with a period of 16 msec in this embodiment.
When this processing is started, the CPU 381 permits multiple interrupts as preparation for executing the processing (step S100), and performs noise cancellation / determination processing (step S101). Then, the terminal level of the interrupt terminal is confirmed (step S102). If the terminal level is abnormal, it is determined that the display control process has been started based on an abnormal trigger due to the influence of noise or the like, and the process is terminated as it is.

  When the terminal level is normal (step S102), the CPU 381 inputs a command from the sub-control board 35 (step S103), and executes the character display control process based on this command (step S200). The character display control process is a process for outputting a drawing command to the VDP 386 based on the command.

F2. Character display control processing:
FIG. 11 is a flowchart of the character display control process. This is a process corresponding to step S200 of the display control process (FIG. 10).
When the process is started, the CPU 381 initializes the sprite register 385s and sets the VDP register 385v (step S201). In the VDP register 385v, condition settings for generating display data, for example, the overlay order of layers constituting the drawing command, display / non-display settings, and the like are set.

Next, the CPU 381 analyzes the contents of the display command received from the sub control board 35 (step S202), and sets a drawing command in the sprite register 385s (step S203). As described above, the sprite register 385s is a double buffer (see FIG. 3). In this embodiment, the first buffer of the sprite register 385s is dedicated to writing, and the second buffer is dedicated to reading. When the CPU 381 finishes writing to the first buffer, the drawing command is transferred to the second buffer and used for display data generation by the VDP 385.
In the setting of the drawing command (step S203), the screen data SD shown in FIG. 9 is read and given by the setting information SPL in both cases where the display object is a 256-color sprite and the frame image generated from the moving image. This is the same in that each piece of information is set in the sprite register 385s. The difference between the two is that the setting of “color format designation” and the setting of “color palette number” are different in the setting information SPL.

  Here, when the push button 9 is operated by the player (step S204) or when there is a hold command (step S205), the CPU 381 executes a response image display process (step S210). The response image display process is a hold command that displays an image corresponding to the operation of the push button 9 is a drawing command that is held without being executed in the previous response image display process. The conditions for generating the hold command will be described in the response image display process described later.

  When the above processing is completed, the CPU 381 instructs the VDP 385 to perform DMA transfer (step S250), and ends the drawing command output processing. The VDP 385 uses the DMA transfer as a trigger to transfer the drawing command written in the first buffer of the sprite register 385s to the second buffer, and starts display data generation processing using this drawing command.

F3. Response image display processing:
FIG. 12 is a flowchart of the response image display process. This process corresponds to step S210 of the character display control process (FIG. 11), and is a process for displaying an image corresponding to the operation of the push button 9.
The processing contents differ between when displaying using 256 color sprites and when displaying moving images. In the case where 256-color sprites are used, as shown in FIG. 4, processing for displaying an image for stopping or reversing the design is performed by operating the push button 9. When a moving image is displayed, a process for displaying an image corresponding to the operation of the push button 9 on the front of the moving image is performed.

Therefore, the CPU 381 determines whether or not a moving image is displayed (step S211). If the moving image is not a moving image, that is, if display is performed using a 256-color sprite, the CPU 381 performs sprite coordinate correction processing (step S211). S212). The determination of whether or not the image is a moving image may be made by referring to the color format designation in the sprite setting information designated by the screen data (see FIG. 9).
The sprite coordinate correcting process is a process of correcting the coordinate value of the sprite setting information (see FIG. 9) according to the operation of the push button 9. As shown in FIGS. 4 (b) and 4 (c), when the change of the symbol is stopped, the coordinate value of the symbol corresponding to the lottery result is fixed at the stop position, and other symbols are not displayed. Good. As shown in FIG. 4D, when the symbol is reversed, the symbol coordinates may be moved in the reverse rotation direction in accordance with the operation of the push button 9 rather than the position to be originally displayed. The stop and the reverse of the symbol can be arbitrarily used according to the gaming state.

  When the moving image is displayed (step S211), the CPU 381 refers to the information on the response image display area in the setting information, and specifies the response image display area (step S220). An example of the response image display area is shown in the figure. For example, it is assumed that an area A1 in the drawing is set as a display prohibition area of a response image for a frame image of a moving image. In addition, in the sprite that is set to display the frame image together, it is assumed that the area A2 is set as the response image display prohibited area. In this state, a portion that does not correspond to the display prohibited area for any sprite, that is, an area AA that is not hatched in the figure is specified as the display area of the response image. Here, a case where a plurality of sprites including a frame image are designated by screen data is illustrated, but when only a frame image is designated, for example, a portion excluding the area A1 in the figure is a response image. Is specified as the display area.

Next, the CPU 381 determines whether or not the response image can be displayed based on the identification result (step S222). If the response image display area is large enough to display the response image, it is determined that display is possible, and otherwise it is determined that display is impossible. If the CPU 381 determines that display is not possible, the CPU 381 suspends the response image drawing command (step S224), and ends the response image display processing.
As described earlier in the character display control process (FIG. 11), when the hold command remains, the response image display process is executed regardless of whether or not the push button is operated (steps S205 and S210). The drawing command put on hold in the above process is executed when the response image can be displayed next. Strictly speaking, the response image is displayed after a slight delay from the time when the player operates the push button. However, since the display control is executed by an interruption process with a period of 16 msec, this delay is displayed. Can be suppressed to such an extent that you do not feel uncomfortable. In order to sufficiently reduce the player's uncomfortable feeling, an upper limit may be set for the suspension period of the response image rendering command, and the rendering command that has been suspended for a predetermined time may be deleted.

  When determining that display is possible, the CPU 381 sets a response image drawing command (step S223). In the present embodiment, the response image is allowed to be moved or enlarged according to the position and size of the displayable area. Therefore, in the process of step S223, the CPU 381 sets the coordinates and the enlargement ratio according to the displayable area in the response image drawing command, that is, the setting information shown in FIG. For example, the coordinate can be set so that the position of the centroid of the response image matches the centroid of the displayable area. In addition, after setting the coordinates in this way, the enlargement ratio can be set so that the entire response image fits within the displayable area.

  Regarding the response image, only the change of the position or only the enlargement may be allowed, or the change of both the position and the enlargement ratio may be prohibited. In addition, if the change of the coordinates and the enlargement rate is allowed without limitation, there is a possibility that the response image is displayed in a state that is reduced so as to be invisible to the player. In order to avoid such an adverse effect, a change allowable range may be provided for the coordinates and the enlargement ratio. In any aspect, whether or not the response image can be displayed in step S222 may be determined based on whether or not the coordinates and the enlargement ratio can be changed.

G. effect:
According to the gaming machine of the present embodiment described above, it is possible to perform full-color symbol variation display by using a video generated corresponding to all combinations of variation patterns and lottery results, and to enhance interest. Can do. Further, when displaying a response image in response to the operation of the push button 9 during the effect display using the moving image, it is possible to specify a frame image to be displayed on the LCD 16 and determine whether or not the response image can be displayed. Therefore, it is possible to display the response image while avoiding adverse effects such as obscuring an important part represented in the frame image.
As mentioned above, although the various Example of this invention was described, it cannot be overemphasized that this invention is not limited to these Examples, and can take a various structure in the range which does not deviate from the meaning.
