Description

  The present invention relates to a technique for image presentation applicable to a gaming machine such as a slot machine.

  In a gaming machine such as a slot machine in recent years, an image effect in which an object of a 3D image composed of a plurality of polygons is arranged in a virtual 3D space is performed, and an effect that is more realistic than a 2D image. It tends to be used (see, for example, Patent Document 1). Such a three-dimensional image is calculated in real time by the image processing apparatus and displayed on the display screen.

JP 2001-112985 A

  However, depending on the type of object in the three-dimensional space, the representation with a three-dimensional image may be contrary to the reality. For example, an object having a pattern in which fine pattern images are closely arranged tends to be unclear when expressed in a three-dimensional image. In addition, there is a problem that the amount of data to be retained increases, for example, in order to express an object by animation, a plurality of two-dimensional image data to be texture-mapped for each polygon constituting the object must be prepared.

  Accordingly, an object of the present invention is to enable a clear image to be displayed in a virtual three-dimensional space as compared to the case where the object is represented by three-dimensional image data depending on the type of the object, and to retain an object for animation display. The purpose is to reduce the amount of data that should be kept.

  The present invention is an image processing apparatus that performs image processing for displaying a moving image in real time, and a position specifying unit that specifies a display position of a dot-shaped image in at least one object in a three-dimensional space; Image data generating means for generating dot-shaped image data corresponding to each position specified by the position specifying means, and generating three-dimensional image data for an object other than the object in the three-dimensional space; and the image Image combining means for combining the dot-shaped image data generated by the data generating means and the three-dimensional image data, and display control means for performing display control of the combined image data generated by the combining processing by the image combining means It is characterized by having.

  As described above, according to the present invention, in addition to an object based on 3D image data, an object based on dot-shaped image data can be combined and displayed in a 3D space. Therefore, for example, an object having a pattern in which fine pattern images are closely arranged is expressed by dot-shaped image data, so that it is clearer than that expressed by three-dimensional image data in a virtual three-dimensional space. When an image can be displayed, and when the object is displayed as an animation, a plurality of two-dimensional image data for texture mapping is prepared for each of a plurality of polygons constituting the object, as in the case of expressing the object as a three-dimensional image. Therefore, it is possible to reduce the amount of data to be held.

  In the present invention, there is further provided an image designating unit for designating at least one of a size and a color of the dot-shaped image, and the image data generating unit is based on contents designated by the image designating unit. The dot-shaped image data corresponding to each position is generated.

  As described above, in the present invention, when generating dot-shaped image data, at least one of the size and color of the dot-shaped image is specified, and the dot-shaped image data is specified based on the specified content. It is preferable to generate image data. Further, for example, by updating the designated content at an arbitrary time interval, the animation of the object can be displayed.

  According to the present invention, in a virtual three-dimensional space, it is possible to display a clear image as compared with the case where it is expressed by three-dimensional image data depending on the type of the object, and the image is retained for animation display of the object. The amount of data that should be reduced can be reduced.

In the present embodiment, for example, the following units 101, 103, 106, 107, 108, and 109 are configured from programs recorded in the main CPU 51 and the ROM 52. For example, the following flag information storage unit 105 is provided in the RAM 53. For example, the following lottery table 102 data is stored in the ROM 52.

(Role lottery section 103)
The role lottery unit 103 draws a role (special role, small role, replay, etc.). Here, the special combination is a combination that is a game different from the normal game and is shifted to a plurality of special games that are advantageous to the player. A small role is a role of paying out a number of medals to a player according to the type of the small role. Replay is a role that gives a player the right to replay while maintaining the number of medals inserted in the previous game.

  Further, the role lottery unit 103 obtains one random number after generating a random number internally for each game, refers to the lottery table 102 stored in the ROM 52, and based on the area to which the obtained random number belongs, The presence / absence of a winning combination and the winning combination are determined.

  That is, the role lottery unit 103 generates random numbers in a predetermined area (0 to 65535 in decimal notation), for example, and when a predetermined condition is satisfied, for example, when the start switch 41 is operated, Get the numeric value. In the lottery table 102, a special role winning area, a small role winning area, a replay winning area, a non-winning area (losing) area, and the like are set at a predetermined ratio with respect to random numbers that can be acquired by the role lottery unit 103. ing.

  Then, the combination lottery unit 103 compares the acquired random number value with the lottery table 102 to determine an area to which the random value belongs, and determines a combination corresponding to the area to which the random value belongs. For example, when the extracted random number value belongs to the special combination winning area, it is determined that the special combination is won, and when it belongs to the non-winning area, it is determined to be lost. If any combination is won, the flag for the combination is turned on.

(Control unit 101)
The control unit 101 controls the operation timing of the combination lottery unit 103, a reel control unit 106 and a winning determination unit 107, which will be described later. For example, on the condition that the start switch 41 is operated, the control unit 101 causes the combination lottery unit 103 to perform combination lottery, causes the reel control unit 106 to start rotating the reel group 31, and sets the stop switch The reel control unit 106 performs stop control of the reel group 31 on the condition that the group 42 has been operated, and further causes the winning determination unit 107 to perform a prize determination on the condition that the reel group 31 has stopped. The operation of the control unit 101 is not limited to these.

The winning determination unit 107 determines whether or not a combination of symbols in the active line group 22 is arranged in any of the active lines that are active, and if there is an in-line combination, It is determined that the prize has been won. At this time, the winning determination unit 106 determines, for example, a symbol positioned on the effective line by detecting an angle, the number of steps, or the like when the stepping motor is stopped, and based on this, determines whether or not a winning combination has been won. . When a table is used for control when stopping the reels 31L, 31C, and 31R, the winning determination unit 107 does not determine the combination of symbols after the reels 31L, 31C, and 31R actually stop. Alternatively, when the reel control unit 106 determines the stop position of the reel group 31 using a table, the combination of symbols that stop on the effective line may be determined.

(Special game control unit 108)
As a result of the determination by the winning determination unit 107, the special game control unit 108 controls the special game from the next game until a predetermined end condition is satisfied. For example, the special game control unit 108 causes the reel control unit 106 to perform reel control for special games according to the lottery result of the role lottery unit 103 during the special game, or causes the sub control board 60 to perform special game effects. Or let it be done.

As a result of the lottery, if any combination is won, the flag of the combination is turned on in the flag information storage unit 105. The lottery result by the combination lottery unit 103 is transmitted as winning combination information to the sub-control board 60 via the I / F circuit 54 (step S103).

  The reel control unit 106 determines whether any one of the stop switch groups 42 has been operated (step S104). When any one of the stop switches is operated (step S104 / YES), reel control is performed so that the winning combination can be won, and the rotation of the reel corresponding to the operated stop switch is stopped (step S104). S105). If no winning combination has been won in the winning lottery process in step S102 (if the winning combination has been won), the reel control unit 106 corresponds to the case where no winning combination has been won in step S105. Reel control is performed.

  Subsequently, the reel control unit 106 determines whether all the stop switches are operated and all the reels are stopped (step S106). When all the reels have not stopped yet (step S106 / NO), the processing from the detection processing of presence / absence of the stop switch operation in step S104 is repeated.

  When all the reels are stopped (step S106 / YES), the winning determination unit 107 determines the presence / absence of winning based on the combination of symbols arranged on the activated effective line (step S107). As a result, if there is any winning (step S107 / YES), a winning process corresponding to the winning combination is executed (step S108). That is, when the winning combination is a special combination, the special combination special game control unit 108 performs a transition process for executing the special game from the next game until the predetermined end condition is satisfied. On the other hand, if it is determined in step S107 that there is no winning (step S107 / NO), the process returns to step S101. Subsequently, during the special role game, the special game control unit 108 provides the reel control unit 106 with a reel in the special game so as to provide the player with a game state corresponding to the big bonus game or the regular bonus game as the special role. Control is performed, or the sub control board 60 is caused to perform special games. When the specified number of games of the big bonus game or the regular bonus game is finished, a process of shifting to the normal game is performed.

  If the winning combination is not a special combination, if the flag of the special combination is stored in the on state in the flag information storage unit 105, the storage state of the flag in the flag information storage unit 105 is carried over to the next game.

  When the winning combination is replay, the winning determination unit 107 causes the control unit 101 to carry a bet (the number of bets) on the game to the next game. On the other hand, when the winning combination is neither a special combination nor a replay, the payout control unit 109 causes the hopper device 93 to pay out the number of medals corresponding to the winning combination.

  Next, the operation of the sub control board 60 will be described with reference to FIGS. Here, only a specific effect control operation using a composite image of a dot image and a three-dimensional image will be described, but the sub-control board 60 of the present embodiment can execute a basic control operation for effect. Of course there is.

  First, when the sub-control board 60 receives winning combination information from the main control board 50 and the effect pattern selection unit 201 selects an effect pattern using a composite image of a dot image and a three-dimensional image, the effect control unit 202 selects Production control based on the produced production pattern is performed.

  The image control unit 301 controls the image data generation unit 304 to generate image data corresponding to the production pattern selected by the production pattern selection unit 201. In response to the control, the dot image generation unit 3041 of the image data generation unit 304 reads information about the dot image such as the size, shape, and color of each dot image to be used from the image data ROM 65 (step S71). Next, the dot image generation unit 3041 generates dot image data and writes the generated dot image data into the video RAM 66 (step S72). FIG. 8 is a flowchart showing in detail the processing in step S72.

  The dot image generation unit 3041 reads display position information of the first dot image from the image data ROM 65 (step S721). The display position information read from the image data ROM 65 at this time is position information within one or a plurality of objects in accordance with the control of the image control unit 301, and is representative coordinate information of the display range of the dot image. . For example, as shown in FIG. 9A, the position coordinates in the ceiling object 902 of the virtual three-dimensional space 901 are indicated by the display position coordinates.

  Subsequently, the dot image generation unit 3041 is based on the display position information read in step S721, the information on the dot image read in step S71 corresponding to the display position information, the position of the current viewpoint, and the like. The dot image data of the first dot image is generated. The image composition unit 305 writes the generated dot image data in a recording area corresponding to the display position of the dot image in the video RAM 66 (step S722). Note that the 3D image data generated by the 3D image generation unit 3042 is written in a recording area other than the recording area in the video RAM 66. In this way, the dot image data and the three-dimensional image data are synthesized (hereinafter, the synthesized image data is referred to as synthesized image data).

  Subsequently, the dot image generation unit 3041 determines whether or not the display position information of all dot images has been read from the image data ROM 65 (step S723), and if there is a dot image for which display position information has not been read yet. Then, the process of step S721 is executed. The dot image generation unit 3041 and the image composition unit 305 repeatedly execute the processing of step S721 to step S724 for all dot images to be displayed on each object, and then shift the processing to step S73 of FIG.

  Subsequently, the dot image generation unit 3041 performs a swap process between the composite image data written in the video RAM 73 in step S72 and the image data that is held in the image display device 40 and is currently displayed (step S73). That is, the currently displayed image data is transferred from the image display device 40 and recorded in the video RAM 73, while the composite image data recorded in the video RAM 73 is transferred to the image display device 40 and recorded in the video RAM 73. The image data exchanged with the image data held in the image display device 40 is exchanged.

  Subsequently, the display control unit 306 controls the display device 40 to display the image data transferred from the video RAM 73 in step S73 (step S74).

  Then, the process shifts again from step S72 to similarly generate the composite image data of the next frame, and the video RAM 66 is overwritten with the generated composite image data. In step S73, a swap process between the composite image data of the next frame recorded this time in the video RAM 66 and the composite image data currently displayed on the image display device 40 is executed. In step S74, display control of the composite image data transferred from the video RAM 66 is performed. By repeatedly executing the processing from step S72 to step S74 in this way, it is possible to display a dot image animation. It should be noted that, by updating the 3D image data recorded in the video RAM 66 every frame, a 3D image can be displayed as an animation.

  As described above, according to the present embodiment, in addition to the object of the three-dimensional image, the object of the dot image can be combined and displayed in the three-dimensional space. Therefore, FIG. 9B is a diagram showing the ceiling object 902 of FIG. 9A from the front. In this way, for example, an object having a pattern in which fine pattern images are closely arranged is represented by a dot image. As a result, a clearer image can be displayed compared to the case where the object is displayed in a virtual three-dimensional space, and when the object is displayed as an animation, the object is displayed as a three-dimensional image. In addition, it is not necessary to prepare a plurality of two-dimensional image data for texture mapping for each of a plurality of polygons constituting the object, and the amount of data to be retained can be reduced.

  The embodiment described above can be realized by a computer executing a program. The means for supplying the program to the computer may be a computer-readable recording medium such as a CD-ROM recording the program or a transmission medium such as the Internet for transmitting the program. As mentioned above, although embodiment of this invention has been explained in full detail with reference to drawings, a concrete structure is not restricted to said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
