Abstract

PROBLEM TO BE SOLVED: To reduce a processing load on a VDP (video display processor) when video display is performed by enlarging graphics image data such as a sprite image by the VDP functioning as a video display processor.SOLUTION: When a command list for transmission to the VDP is generated, a symbol CPU for generating the command list for transmission to the VDP determines whether the enlargement rate of the sprite image indicated by display scheduler data is larger than 100% or not (step S252). When the enlargement rate is larger than 100%, a flag for turning on bilinear interpolation is set in a command for instructing picture drawing processing with respect to the VDP (step S253). When the enlargement rate is equal to or less than 100%, a flag for turning off the bilinear interpolation is set (step S254).

Description

  The present invention relates to a gaming machine that executes an effect display in accordance with the progress of a game.

As this type of gaming machine, there is a gaming machine that displays video based on material image data stored in a character ROM as the game progresses, such as a pachinko machine (see, for example, Patent Document 1). .

In such a known gaming machine, as an effect display operation according to the progress of the game, a video is displayed by superimposing a sprite image prepared in advance on a background image, so that a player who is in contact with the video can be visually informed. The effect is given. In order to enhance such a visual effect, in recent pachinko machines, a so-called video display processor (VDP) is used.
) Is present. This video display processor displays a video composed of a background image and a sprite image on a display device using character data read from the character ROM in accordance with an instruction from a display control processor that controls video display. .

JP 2007-75480 A

In gaming machines that display video using such sprite images, various sprite images generated in advance are stored as sprite data in the character ROM, and the VDP reads the sprite data from the character ROM and performs various drawing operations. . Here, since only basic data is prepared as the sprite data prepared in advance, in order to perform various images, the display position, the rotation angle, the enlargement ratio, etc. in the display device are set with respect to the VDP. It is necessary to instruct.

When enlarging a sprite image prepared in advance, if the original sprite image is enlarged as it is, an adverse effect such as a jagged outline may occur and an unnatural image may occur.

In order to prevent such adverse effects, image data is interpolated using image interpolation processing such as bilinear interpolation when enlarging an image. Here, bilinear interpolation is an interpolation method in which the pixel value of the desired coordinate is calculated by calculating the weighted average value of the surrounding four pixel values.

However, in order to perform bilinear interpolation, it is necessary to perform a large amount of calculation for obtaining the pixel value of each pixel constituting the image, which places a load on the VDP. In particular, when an image using a sprite image having a different enlargement ratio for each frame is to be realized, the processing load of the VDP becomes large.

In recent gaming machines, it has been required to display various effects, and the number of sprite images used in one frame, the types of effects for sprite images, and the like are greatly increasing. As a result, the processing load on the VDP increases further, and depending on the case, the content of the video display is limited or continuous video display becomes impossible.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gaming machine capable of reducing the processing load of VDP when displaying material image data such as sprite images by VDP functioning as a video display processor. And

A gaming machine of the present invention includes a game control unit that controls a game operation using a game medium,
An effect control unit that controls an effect operation accompanying the game operation by the control of the game control unit,
In a gaming machine comprising a display device that performs a display operation under the control of the effect control unit,
The production control unit
In addition to storing material image data used for displaying material images required for video in a nonvolatile manner,
A non-volatile video memory for storing in a non-volatile manner scheduler information including information relating to a configuration of a video to be displayed and information for specifying material image data necessary for rendering each scene constituting the video to be displayed; A volatile video memory capable of storing image data in a volatile manner;
A video display processor for displaying video on the display device;
A command list comprising a plurality of commands for instructing the video display processor to perform video display processing in order to execute a display control program for controlling video display and realize video display based on the scheduler data. A display control processor for generating and transferring to the video display processor;
Including
The video display processor
Based on the command list transferred from the display control processor, the material image data corresponding to the video to be displayed is read from the nonvolatile video memory and expanded in the volatile video memory and also expanded in the volatile video memory Video displayed using the material image data is displayed on the display device,
The display control processor includes:
A determination unit that determines whether or not an enlargement ratio of the material image indicated in the scheduler data is larger than a preset value when generating a command list for transfer to the video display processor;
And setting means for setting a command for turning on image interpolation processing in the command list when the enlargement ratio of the material image is larger than a preset value by the determining means.

In the gaming machine of the present invention, the image interpolation process is executed only when the enlargement ratio of the material image is larger than a preset value, and when the enlargement ratio of the material image is less than the preset value, the image interpolation is performed. Processing is not performed. Therefore, according to the gaming machine of the present invention, it is possible to reduce the processing load of the video display processor as compared with the case where video display is always performed by performing image interpolation processing.

FIG. 2 is a block diagram illustrating an electrical configuration example of the pachinko machine 1.
First, the main control board 3 (game control unit) is connected to a board such as the sub control board 35 (effect control unit) and the payout control board 25. The sub control board 35 is connected to the decorative design control board 30 that controls the display operation, and the payout control board 25 is connected to the launch control board 47 and the prize ball payout device 21.

The decorative symbol control board 30 is connected to the decorative symbol display device 16. In the present embodiment, the sub control board 35 (effect control board) and the decorative design control board 30 (display control board) are separate, but the sub control board 35 and the decorative design control board are not limited thereto. 30 may be integrated, and the sub-control board 35 (production control unit) may have the function of the decorative design control board 30. When such a form is adopted, the sub control board 35 is directly connected to the decorative symbol display device 16.

The sub control board 35 transmits to the decorative design control board 30 an effect display command for controlling the effect display operation according to the progress of the game during the game operation. The decorative symbol control board 30 receives the effect display command and the like, and causes the decorative symbol display device 16 to display an image according to the progress of the game based on the effect display command. This effect display command includes an effect display pattern number designated by the sub control board 35, and this effect display pattern number represents a number corresponding to the effect display pattern to be executed and controlled by the decorative symbol control board 30. Yes. The sub control board 35 includes a lamp relay board 32 and a lamp relay board 34.

The main control board 3 includes a CPU 3a (hereinafter referred to as “main CPU”), a RAM 3b,
It includes electronic components such as a ROM 3c, an input / output interface, etc. (all not shown). The main control board 3 is connected with a winning detector 15a (winning detecting means) for detecting a winning. This winning detector 15a has various winning ports (start winning port 1) in the game area.
5b, large winning opening 15c, general winning opening, etc.) (hereinafter referred to as starting winning opening 15b)
) Is detected, and a detection signal is output to the main control board 3. The gate passage detector (gate switch) 13 a detects that a game ball has passed through the gate port 13, and outputs a gate passage signal as a detection signal to the main control board 3.

Control of the gaming operation by the main control board 3 is performed, for example, by the main CPU 3a executing a control program (hereinafter referred to as “main control program”). The main control program generates a random number on the software, and acquires a random number value (a jackpot determination random number value) in response to a start winning (referred to as “big hit lottery” in the present embodiment). Then, the main control program determines whether or not the acquired random value matches the jackpot random value at the jackpot determination timing described later (referred to as “determination” in the present embodiment),
If it is determined that the two random numbers match, it is determined as “big hit”, whereas if it is determined that they do not match, it is determined as “out”. Here, the big hit determination timing refers to the time when the special symbol variation display based on the start winning is started after the start winning.

The main control program starts the special symbol variation display by the special symbol display device 41 after the start winning is made in this way, and when the predetermined variation time has elapsed, the special symbol is displayed according to the jackpot lottery result. A stop symbol is displayed on the display device 41. In addition, the above "big hit"
Includes so-called “probable big hits” and so-called “ordinary big hits”.

When the result of the big hit lottery and determination is a big win, the main control program starts the variable display, and after stopping the variable display, shifts to the special gaming state. In this special game state, the main control program repeatedly operates, for example, the special prize opening solenoid 18 for a predetermined number of times (round operation), for example, for 15 rounds, the special prize opening 15c is in a state where it is easy to accept the game ball. . At this time, the player can win more prize balls by winning a game ball (game medium) while the special winning opening 15c is opened. In addition to the above, there are various types of game operation control by the main control board 3, but since all are well-known, detailed description is omitted here.

When the sub control program receives a command or the like from the main control board 3 (lottery result, effect command, gaming state command, etc.), the received control command is analyzed.

The sub-control program executes a lottery (hereinafter referred to as “effect lottery”) as to what effect pattern should be controlled according to the lottery result obtained from the analysis result of the command and the variation time. Specifically, the sub-control program manages an effect control scheduler, and this effect control scheduler executes for each lottery result (depending on whether it is a “hit” or “out”). Multiple production patterns to be managed are managed. Furthermore, this production control scheduler includes a plurality of production patterns having different lengths of variation time even if the lottery results are the same. Moreover, even if the same lottery result and the variation time are the same, there are a plurality of effect patterns having different effect contents. In this way, the sub-control program executes the effect lottery to select the effect pattern corresponding to the lottery result and the variation time while referring to the effect control scheduler.

After executing such an effect lottery, the sub-control program outputs sound from the speakers 29a and 29b according to the effect pattern over the varying time, or lights the panel decoration lamp 36 in a predetermined color via the lamp relay board 32. The lamp relay board 34
The frame decoration lamp 31 is turned on or off with a predetermined color.

In addition, the sub-control program also selects an effect display pattern related to the variable display by the decorative symbol display device 16 in accordance with the selected effect pattern. After selecting the effect display pattern, the sub control program controls the sub control board 35 to output an effect display command including information on the effect display pattern and the stop symbol to the decorative design control board 30.

When the decorative design control board 30 receives the effect display command output from the sub-control board 35, the decorative design control board 30 shifts to a new effect display operation. Specifically, the decorative design control board 30 is
First, the effect display command received from the sub control board 35 is analyzed, and information related to the effect display pattern and the decoration stop symbol is acquired. Then, the decorative design control board 30 displays the decorative design on the decorative design display device 16 variably over the variation time based on the effect display pattern, and then controls the display so that the decorative design becomes the decorative stop symbol.

That is, the main control board 3 and the payout control board 25 are connected by the upper and lower lines Su and Sd of the serial signal and the transmission lines Au and Ad of the ACK signal provided in parallel therewith.

For example, when the main control board 3 transmits a prize ball command instructing the payout of a prize ball in the serial format through the down line Sd, the payout control board 25 that has received the command sends an ACK signal to the main control board 3 through the transmission line Au. Send. Further, when the payout control board 25 transmits a status command indicating the state of the payout control board 25 (for example, during payout processing) to the main control board 3 through the uplink line Su, the main control board 3 that has received the command sends the transmission line. An ACK signal is transmitted to the payout control board 25 through Ad.

The prize ball payout device 21 performs a game ball payout operation under the control of the payout control board 25. That is, when the payout control board 25 receives a prize ball command from the main control board 3, the payout motor 20 of the prize ball payout device 21 is operated to perform the payout operation for the number instructed by the prize ball command. The payout ball detector 22 detects the number of prize balls actually paid out one by one and feeds it back to the payout control board 25. On the other hand, the motor drive sensor 24 detects the rotation state (rotation angle) of the payout motor 20 and feeds it back to the payout control board 25.

In addition, in addition to the firing motor 49, a signal line from the firing handle 8 is connected to the firing control board 47. The firing handle 8 includes a touch detection unit 48 that detects the contact of a human body (player) and outputs the touch detection signal to the firing control board 47. The firing handle 8 has a built-in firing switch (not shown), and outputs an ON signal to the firing control board 47 by operating the firing handle 8. This launch control board 47
Has a function of permitting a game ball launching operation when a card unit connection signal output by the card unit 12 as the inter-bed sand is input via the payout control board 25. The launch control board 47 permits the drive of the launch motor 49 only after receiving the card unit connection signal, the touch detection signal, and the ON signal, thereby allowing the game ball to be launched.

When the payout CPU 25a of the payout control board 25 detects a failure such as a so-called ball bite, a ball breakage, a full tank, or a connection abnormality between the main control board 3 and the payout control board 25, error information corresponding to the type of the fault is displayed.

The decorative symbol control board 30 (production control unit) includes a source ROM (character ROM) 340 and a graphic processor unit (hereinafter referred to as “GPU”) 300.

The decorative symbol control board 30 has a function of controlling an effect display operation based on an effect display command from the sub control board 35 and the like. The decorative design control board 30 is connected to the decorative design display device 16 described above, and outputs a video signal corresponding to the video to be displayed to the decorative design display device 16 based on the effect display command or the like.

Here, in this embodiment, the video is composed of a combination of a plurality of scenes (story), and each scene is composed of a combination of a large number of frames. Each of these scenes is continuously displayed in a predetermined order. Each scene is visually configured by displaying a number of frames one after another. Each scene includes at least one of a moving image and a sprite image, and is, for example, a video in which one scene of a movie is used as a moving image as a background and a pattern is displayed as a sprite image on the background. In this embodiment, by continuously switching and displaying each frame of these frames one after another at a frame rate obtained by dividing the video by 60 frames per second,
An image whose display mode is dynamically changed is represented. In the present embodiment, the moving image or sprite image used when creating this frame (frame) is referred to as “scene material”. In the present embodiment, as a scene material, except for a portion that needs to be touched particularly on a moving image,

(3-1. Example of hardware configuration)
Hereinafter, each component mounted on the decorative design control board 30 will be described in detail.

(3-1-1. Source ROM 340)
The source ROM 340 functions as a nonvolatile video memory that stores various material image data such as sprite data for displaying a sprite image in a nonvolatile manner, and is connected to the GPU 300 via a bus line. The memory space of the source ROM 340 will be described later.

The sprite data is stored in the source ROM 340 in a state where the data structure is compressed by a preset reversible compression method. On the other hand, the moving image data is stored in the source ROM 340 in a state where the data structure is compressed by a preset irreversible compression method.

(3-1-2. Configuration Example of GPU 300)
As shown in FIG. 3, the GPU 300 includes a control ROM 301, an SDRAM (Synchrono
us Dynamic Random Access Memory) 302 and command interface (I / F) 303
And a symbol CPU 311 and a VDP (Video Display Processor) 330.
Between the symbol CPU 311, SDRAM 302, control ROM 301, and VDP 330 is a bus 30.
7 is connected.

The command interface 303 receives the effect display command from the sub control board 35 and transfers the received effect display command to the symbol CPU 311.

The control ROM 301 is configured by a flash ROM, for example, and stores a display control program for controlling the operation of the symbol CPU 311 and display scheduler data (scheduler data). The display scheduler data is data including information for specifying material image data such as information relating to the configuration of the video to be displayed and sprite data necessary for rendering each scene constituting the video to be displayed.

The symbol CPU 311 operates based on the display control program stored in the control ROM 301, and instructs the VDP 330 to perform video display processing in order to realize video display based on the display scheduler data stored in the control ROM 301. A command list including a plurality of commands is generated and transferred to the VDP 330 by DMA (Direct Memory Access).

The control ROM 301 stores a plurality of display scheduler data corresponding to various video displays. Therefore, the design CPU 311 specifies the content of the video display to be displayed by the effect display command transferred from the command interface 303, reads out the display scheduler data corresponding to the specified video display content from the control ROM 301,
A command list is generated so that video display based on the read display scheduler data is realized.

The SDRAM 302 is a storage area used for temporarily storing a command list generated by the symbol CPU 311 and temporarily storing various data.

The VDP 330 functions as a video display processor for displaying video on the decorative symbol display device 16 by sequentially executing a plurality of commands included in the command list transferred from the symbol CPU 311. Based on the command list transferred from the design CPU 311, the VDP 330 reads material image data such as sprite data corresponding to the video to be displayed from the source ROM 340 and draws each scene constituting the video.
Various image displays are realized by transmitting the generated drawing data to the decorative symbol display device 16.

(3-1-3. Configuration example of VDP330)
Next, the configuration of the VDP 330 for displaying images on the decorative symbol display device 16 is shown in FIG.
Will be described with reference to FIG.

As shown in FIG. 4, the VDP 330 includes a CPU I / F (interface) 331,
Data transfer circuit 332, bus I / F (interface) 333, decoder 334, drawing circuit 335, data storage memory 336, frame buffer memory 337, display circuit 338
Is included.

The CPU interface (I / F) 331 receives the command list transferred from the symbol CPU 311.

The data storage memory 336 is a so-called VRAM (Video RAM), and functions as a volatile video memory for developing various material image data necessary for drawing processing such as sprite data and moving image data.

The data transfer circuit 332 is based on a command list received from the symbol CPU 311 via the CPU interface 331, and sprite data necessary for video display to be displayed.
Source image data such as moving image data is sent to the source ROM 34 via the bus interface 333.
The data is read from 0 and expanded in the data storage memory 336 (material image data expansion means).

Since the sprite data is stored in the source ROM 340 in a state where the data structure is compressed by a reversible compression method, the source RO via the bus interface 333 is used.
The sprite data read from M340 is decoded (decompressed) by the decoder 334 and then stored in the data storage memory 336.

The frame buffer memory 337 is realized by a VRAM similarly to the data storage memory 336, and has a configuration capable of storing video data drawn by the drawing circuit 335 in a volatile manner. Note that the frame buffer memory 337 can draw and store video data for two frames. While the video data for one frame has been drawn and stored by the drawing circuit 335, the frame buffer memory 337 has already drawn. The display circuit 338 displays the data of the frame for which the drawing process is completed.
Can be displayed on the decorative symbol display device 16.

The drawing circuit 335 performs drawing processing using material image data such as sprite data and moving image data stored in the data storage memory 336 based on the command list from the symbol CPU 311 received by the CPU interface 331. Then, video data is generated for each frame constituting the video to be displayed and stored in the frame buffer memory 337.

The display circuit 338 generates a synchronization signal (V blank signal or the like) to the decorative symbol display device 16 and is based on the image data generated in the frame buffer area of the frame buffer memory 337 while synchronizing with the synchronization signal. Decorative design display device 16 for video signal

In the present embodiment, the case where the data storage memory 336 for storing the various material image data read from the source ROM 340 in a volatile manner is provided in the VDP 330 will be described. It is not limited to such a configuration. For example, the present invention is similarly applied to a gaming machine having a configuration in which a volatile video memory for volatile storage of various material image data read from the source ROM 340 is provided outside the VDP 330. It is possible to apply.

(3-2. Memory space of control ROM 301)
Next, the memory space of the control ROM 301 described above will be described.
As shown in FIG. 5, the control ROM 301 stores a display control program 401 for controlling the operation of the symbol CPU 311 and display scheduler data 402. The display scheduler data 402 includes information for specifying material image data such as sprite data necessary for drawing each scene constituting the video to be displayed and information regarding the configuration of the video to be displayed.

A frame number 501 indicates to which frame the display scheduler data 402 is displayed. A character number 502 indicates a number for identifying sprite data to be used from among a plurality of sprite data. X-coordinate 503 and Y-coordinate 504 indicate the position where the sprite image is displayed on the display screen. Base point position 5
05 indicates the location of the base point when designating the display position of the sprite image. The X direction enlargement factor 506 and the Y direction enlargement factor 507 indicate how much the sprite image is enlarged (or reduced) in the X direction and the Y direction, respectively. For example, in the range of 0 to 511%. It can be set. The transparency 508 is a value that specifies how much the sprite image is to be displayed when the sprite image is displayed over the background image. For example, the transparency 508 can be specified within a range of 0 to 100%. ing. A rotation angle 509 is a value for designating an angle for displaying a sprite image.

Here, the display scheduler data 402 is not prepared for all frames, but the display scheduler data 402 is prepared only for a specific frame, and the video for the intermediate frame is displayed as a prepared display. The data is interpolated and drawn with reference to the scheduler data 402.

A specific example of such display scheduler data 402 is shown in FIG. In FIG. 7, all set values of the display scheduler data 402 are not shown, and the frame number 501, the character number 502, the X coordinate 503, the Y coordinate 504, the X direction enlargement ratio 506, and the Y direction enlargement ratio 507.
Only shown.

In the example shown in FIG. 7, only the display scheduler data 402 for the first, thirty, and sixtyth frames is set, and the video display of the second to the 29th, the 31st to the 59th frames in the middle is The calculation is made with reference to the values set in the 1st, 30th and 60th frames. For example, it is calculated from the value set in the first frame and the value set in the 30th frame, and as the value of the second frame, the X coordinate 6148 pixels, the Y coordinate 4612 pixels, X
The values of the direction expansion rate of 102% and the Y direction expansion rate of 100% are used.

Here, in the present embodiment, a case where a one-second video display is composed of 60 frames will be described. In this case, the frame period is about 16.7 ms.

(3-3. Memory space of source ROM 340)
Next, the memory space of the source ROM 340 described above will be described.
As shown in FIG. 8, the source ROM 340 displays sprite data 601 for displaying a sprite image generated in advance for displaying a specific video, palette data 602 for specifying a color, and a background image. Various material image data such as moving image data 603 is stored.

(4. Example of operation of gaming machine 1)
Next, the operation of the gaming machine 1 will be described with reference to the drawings.

(4-1. Game control processing)
Here, on the main control board 3, a main control program for controlling the progress of the game is operating, and the main control program acquires a random number for determining a big hit (a big hit lottery) triggered by a start winning prize. When there is a start win, the main control program compares the acquired jackpot determination random number value with a predetermined hit value at the jackpot determination timing based on the start win, and executes the jackpot determination. At the same time, if there is such a start-up prize, the main control program then continues the blinking state (special symbol variation display state) by the special symbol display device 41 for the variation time determined by lottery separately, and then the big hit Depending on the results of the lottery and determination, the special symbol display device 41 is turned on or off (displayed state of the stopped symbols).

When such a jackpot determination is executed, the main control board 3 outputs an effect command including the result of the jackpot determination to the sub-control board 35 in parallel with the control of the special symbol display device 41. This effect command includes information regarding the determination result and the variation time during which the effect operation is to be controlled according to the determination result. In the sub-control board 35 that has received the effect command, an effect lottery is executed, and an effect pattern corresponding to the result of the effect lottery is selected. This effect pattern is a pattern for outputting sound or light. Further, on the sub-control board 35, an effect display pattern corresponding to this effect pattern is selected.

This effect display pattern represents a pattern related to which effect display operation should be executed among a plurality of prepared effect display operations over a variable time, and includes information corresponding to each scene to be displayed as the effect display operation. .

Then, the sub control board 35 transmits an effect display command indicating an effect display to be displayed on the decorative symbol display device 16 to the decorative symbol control board 30 based on the selected effect display pattern.

(5. Example of operation of decorative design display board 30)
Next, an operation example when the decorative design display board 30 receives an effect display command from the sub-control board 35 will be described.

(5-1. Operation example of symbol CPU 311)
The effect display command from the sub-control board 35 is received by the command interface 303 of the GPU 300 and transferred to the symbol CPU 311 for processing. This design CPU31
The operation of No. 1 is shown in the flowchart of FIG.

When receiving the effect display command from the sub control board 35 (step S101), the symbol CPU 311 reads display scheduler data 402 corresponding to the effect display pattern specified by the effect display command from the control ROM 301 (step S102).

Then, the symbol CPU 311 generates a command list to be transmitted to the VDP 330 based on the display scheduler data 402 read from the control ROM 301 (
Step S103). The specific operation of the command list generation process will be described later.

Next, the symbol CPU 311 repeats generation of a command list for drawing each sprite image until generation of a command list for all sprite images in one frame is completed, and generation of a command list for all sprite images is performed. When finished (
In step S104, the generated command list is transmitted to the VDP 330 (step S1).
05).

The symbol CPU 311 then performs step S until the processing for all the frames is completed.
The processes from 103 to S105 are repeated (step S106).

(5-2. Command list generation process)
Next, a specific operation of the command list generation process shown in step S103 of the flowchart of FIG. 9 will be described.

(5-2-1. List of main commands used)
First, a list of main commands used in the VDP 330 of this embodiment is shown in FIG.

As shown in FIG. 10, a command name, command data, data size, and command content are set for each command. Here, the command data indicates a 1-byte value set at the head of each command in order to specify the type of command.

For example, for the command “EODL” whose command content is drawing end, “8F” is set as the command data and the data size is 4 bytes.
The command is “XX”.

Note that the list of commands shown in FIG. 10 shows some of the commands that are actually used, and there are also commands that are not shown in FIG.

(5-2-2. Example of command list)
Next, an example of the command list created by the symbol CPU 311 is shown in FIG. Since a command list is created for each frame, when a plurality of sprite images are included in one frame, commands for each sprite image are generated and included in the command list.

In the example shown in FIG. 11, the command for the second sprite image is arranged below the command for the first sprite image. This command list is 4 per row
Each command is divided into bytes, and a 20-byte command is represented as five columns of data.

The command for the first sprite image in the command list example shown in FIG. 11 includes a command “44000001... 00000”. Referring to FIG. 10, the value “44” for the first byte of this command indicates that the command name of this command is “SETBLNDCNST”, and the command content is a fixed value setting in the inter-image calculation.

(5-2-3. Specific processing flow of command list generation processing)
Next, specific processing when a command list is generated in the symbol CPU 311 in the gaming machine 1 of the present embodiment will be described.

When generating the command list for transfer to the VDP 330, the symbol CPU 311 in the present embodiment sets a command common to a plurality of sprite images as a common command in the command list, and sets a command other than the common command for each sprite image. And set it in the command list.

Also, when trying to generate a command for a certain sprite image, the symbol CPU 311 omits the generation of the command if the command to be generated has the same content as the command for another sprite image that has already been generated. To. Here, as a command to be omitted, a command SERF which is a command including setting of transparency of a sprite image
Although the case where COLOR is used will be described, the present invention can be similarly applied even when other commands are omitted.

A specific processing flow of the command list generation processing is shown in the flowchart of FIG.
First, when trying to generate a command list for a frame with the design CPU 311, commands common to a plurality of sprite images are registered as common commands (step S).
201), the initial value of SETCOLOR, which is a command including transparency setting, is stored (
Step S202).

Next, the symbol CPU 311 is a command other than the common command, such as a texture load related command (TXLOAD2AAC), a texture attribute related command (SETTXATR).
Etc.) and commands such as drawing effect related commands (SETEFFECT) are registered in the command list (step S203).

Then, the symbol CPU 311 synthesizes the transparency value with the command SETCOLOR (
Step S204). Then, the symbol CPU 311 determines whether or not the stored transparency value is the same as the value synthesized with the command SETCOLOR (step S205). If it is determined in step S205 that the stored transparency value and the value synthesized with the command SETCOLOR are the same, the symbol CPU 311 determines that the command SETFCO
Sprite drawing command (SPRITE) without registering in LOR command list
Is registered in the command list (step S208).

In step S205, the stored transparency value and the command SETCOLOR are stored.
If it is determined that the value combined with the symbol is not the same, the symbol CPU 311 determines that the command SET
The transparency value synthesized in FCCOLOR is stored (step S206), and the command SETCOLOR which is synthesized in transparency is registered in the command list (step S207). Then, the symbol CPU 311 registers a sprite drawing command (SPRITE) in the command list (step S208).

When the command list is generated for one sprite image in this way, the design CPU 311 determines whether or not the processing of all the sprite images has been completed (step S).
209) If the processing for all sprite images has been completed, the command generation processing is terminated. If all the sprite images have not been processed, the symbol CPU 311 repeats the processing from step S203 to step S208 until all the sprite images have been processed.

An example of the command list generated in this way is shown in FIG. In the example shown in FIG. 13, a command “44000001... 00000” is set as a common command. Therefore, the command for the first sprite image and the command for the second sprite image are common commands “44000001... 00000.
The command "" is omitted without being set. For this reason, when a common command among commands for each sprite image is set as a common command as shown in FIG. 13, the common command shown in FIG. 11 is not used. Compared with the command list generated at the same time, the data amount of the command list can be reduced.

FIG. 14 shows an example of a command list when the command SETCOLOR which has the same transparency is omitted and when it is not omitted. FIG. 14A shows a command S having the same transparency.
FIG. 14B shows an example of a command list when ETFCOLOR is not omitted.
It is an example of a command list when a command SETCOLOR which has the same transparency is omitted.

In FIG. 14B, the command for the first sprite image is “430000”.
Since the command “01 0A040216” is set, this command is omitted in the command for the second sprite image. Therefore, when comparing FIG. 14A and FIG. It can be seen that the data amount of the command list is reduced by omitting the command without setting it in the commands for the second and subsequent sprite images.

(5-2-4. Bilinear interpolation ON / OFF judgment)
Next, bilinear interpolation on / off determination processing will be described. As mentioned above, design C
The PU 311 sets the command list by performing the command list generation process described with reference to the flowchart of FIG. 9, and determines whether bilinear interpolation is turned on or off in the command list creation process. Bilinear interpolation on / off determination is performed for this purpose.

In the gaming machine 1 of the present embodiment, video display is performed using sprite data prepared in advance, but only basic data is prepared as sprite data prepared in advance. Therefore, in order to perform various images, the symbol CPU 311 displays the decorative symbol display device 1.
By displaying the display position, the rotation angle, the enlargement ratio, etc. in FIG. 6 to the VDP 330 by solving the command list, various video displays are realized.

However, when a sprite image prepared in advance is enlarged, if the original sprite image is enlarged as it is, an adverse effect such as a jagged outline portion may occur and the image may become unnatural.

In order to prevent such adverse effects, image data is interpolated using image interpolation processing such as bilinear interpolation when enlarging an image. Here, bilinear interpolation is an interpolation method in which the pixel value of the desired coordinate is calculated by calculating the weighted average value of the surrounding four pixel values.

However, in order to perform bilinear interpolation, it is necessary to perform a large amount of calculation for obtaining the pixel value of each pixel constituting the image, which places a load on the VDP 330. For example, when a video that gradually increases the enlargement ratio of a certain sprite image is to be performed, each pixel value of the sprite image needs to be calculated using bilinear interpolation for each frame. Therefore, when there are a plurality of sprite images in one frame, the processing load of the VDP 330 becomes large.

Therefore, in the gaming machine 1 of the present embodiment, bilinear interpolation is performed when the enlargement ratio of the sprite image is larger than 100%, but the enlargement ratio is 100% or less, and the sprite image is reduced to the original size or reduced. When used, the processing load of the VDP 330 is reduced by not performing bilinear interpolation.

Specifically, when the symbol CPU 311 generates a command list to be transmitted to the VDP 330, the sprite image enlargement rate (X-direction enlargement rate 506 shown in FIG. It is determined whether or not the Y direction enlargement ratio 507) is greater than 100% (determination means). Then, the symbol CPU 311 has a sprite image enlargement ratio of 1.
When it is larger than 00%, a command for turning on the bilinear interpolation is set in the command list, and when the enlargement ratio of the sprite image is 100% or less, the command for turning off the bilinear interpolation is set in the command list. (Setting means)

The symbol CPU 311 then sets the SETEFFE of the various commands shown in FIG.
By turning on or off a specific flag of the command CT, whether to perform bilinear interpolation is set. And VDP330 is symbol CPU31.
With reference to the flag of the SETEFFECT command in the command list generated by 1, whether to perform video display by performing bilinear interpolation or to perform video display without performing bilinear interpolation is switched.

The symbol CPU 311 generates commands using various functions as tools when generating commands to be set in the command list. For example, the symbol CPU 311 uses a function called “Attrset” as shown below to display a coordinate position (
X coordinate 503, Y coordinate 504) and an enlargement factor (X direction enlargement factor 506, Y direction enlargement factor 507) are automatically generated.
Attrset (X coordinate 503, Y coordinate 504, X direction enlargement factor 506, Y direction enlargement factor 5
07)

In addition, an X direction enlargement factor 506 and a Y direction enlargement factor 507 are added to the function called Attrset
By setting, the value of the enlargement ratio is determined in a function called Attrset, and a parameter for designating ON / OFF of bilinear interpolation in a command called SETEFFECT is automatically set.

That is, in the symbol CPU 311, an X direction enlargement factor 506, a function called Attrset,
By simply setting the Y-direction enlargement factor 507, bilinear interpolation is automatically turned on / off.

Next, the operation of this bilinear interpolation on / off process will be described with reference to the flowchart of FIG.

When generating a command list for a sprite image in a certain frame, the symbol CPU 311 refers to the display scheduler data 402 and sets the X-direction enlargement ratio 506 and the Y-direction enlargement ratio 507 to the function Attrset (step S251).

Then, in the function Attrset, it is determined whether any of the X direction enlargement ratio 506 and the Y direction enlargement ratio 507 is greater than 100% (step S252).
If it is greater than 00%, a flag for turning on the bilinear interpolation is set in the command SETEFECT (step S253). If any enlargement ratio is 100% or less, the command S
A flag for turning off bilinear interpolation is set in ETEFFECT (step S254).
).

In this embodiment, the case where a value of 100% is used as a threshold for determining whether bilinear interpolation is turned on or off is described. However, the present invention is limited to such a case. It is not a thing. The reason is that when the enlargement rate is close to 100% and close to the original size, for example, when the enlargement rate is 101% or 102%, even if bilinear interpolation is not performed, an unnatural video display is not obtained. Because there is also. In such a case, 1
A value other than 00% may be set as the threshold value. For example, if the enlargement ratio is 120% or less, the enlargement ratio is 1 in the case where an unnatural image is not obtained without performing bilinear interpolation.
When it is larger than 20%, it is set to perform bilinear interpolation, and the enlargement ratio is 120%.
You may make it set so that bilinear interpolation may not be performed in the following cases.

Furthermore, in this embodiment, a case where bilinear interpolation is used as an image interpolation process for interpolating each pixel value of a sprite image has been described. However, the present invention uses a case where an image interpolation process other than bilinear interpolation is used. However, it can be applied similarly.

If the size of the sprite data prepared in the source ROM 340 is set to the maximum size of the sprite image to be used, the sprite data is always reduced and used. Therefore, if such a method is used, it does not occur when a sprite image prepared in advance is used in an enlarged manner, so that an unnatural video display does not occur even if bilinear interpolation is not performed. However, since it is necessary to prepare a sprite image of the maximum size to be used, the amount of image data becomes large and the source ROM 3 to be consumed is consumed.
40 capacity increases. Therefore, when the number of types of sprite images increases, if it is attempted to prepare all the sprite images in the maximum size, the capacity of the source ROM 340 must be increased, which is not practical in some cases.

(6. Display processing)
Next, display processing performed in the VDP 330 will be described. FIG. 16 is a flowchart showing an example of the procedure of this display process.

First, when receiving a command list from the symbol CPU 311, the VDP 330 stores the received command list in the data storage memory 336 (step S301). Then, based on the received command list, the data transfer circuit 332 reads various material image data such as sprite data and moving image data necessary for video display from the source ROM 340 (step S302).

The material image data such as sprite data transferred from the source ROM 340 is decoded by the decoder 334 and then stored in the data storage memory 336 (step S303).

The drawing circuit 335 performs drawing processing using the material image data stored in the data storage memory 336 based on each command included in the command list received from the symbol CPU 311, and the generated image data is stored in the frame buffer memory. Sequentially stored in 337 (
Step S304). Note that the drawing circuit 335 performs a sprite image enlargement process.
When bilinear interpolation is set to on, bilinear interpolation is performed when the sprite image is enlarged. When bilinear interpolation is set to off, the sprite image is enlarged without performing bilinear interpolation. Process.

Finally, the display circuit 338 converts the image data for one frame stored in the frame buffer memory 337 into a video signal and outputs it to the decorative design display device 16 (step S30).
5).

By performing the display process as shown in FIG. 16 for each frame, VDP3
30 can display an image constituted by continuous display of each scene on the decorative symbol display device 16 based on the command list transferred from the symbol CPU 311.

(7. Reference to usefulness according to this embodiment)
In the gaming machine 1 of the present embodiment, the symbol CPU 311 generates a command list to be transmitted to the VDP 330 when the sprite image enlargement ratio (X-direction enlargement ratio 506, Y When the direction enlargement ratio 507) is larger than 100%, a command for turning on the bilinear interpolation is generated and set in the command list.
If it is less than 00%, a command for turning off bilinear interpolation is generated and set in the command list.

Therefore, in the gaming machine 1 of the present embodiment, when the enlargement ratio is 100% or less and the video display is performed with the original or reduced size of the sprite image, bilinear interpolation with a large processing load on the VDP 330 is performed. Bilinear interpolation is performed only when the enlargement ratio is 100% or more and bilinear interpolation is not performed, resulting in an unnatural video display. For example, when the enlargement ratio is 90%, 95%, 100%, the bilinear interpolation is not performed, and the enlargement ratio is 150%, 200%, 300%,.
If bi-linear interpolation is not performed as in the case where an unnatural image is displayed, bi-linear interpolation is performed.

Therefore, according to the gaming machine 1 of the present embodiment, bilinear interpolation is not performed when the enlargement ratio is 100% or less, and therefore, compared to a case where video display of a sprite image is always performed with bilinear interpolation turned on. , The processing load on the VDP 330 can be reduced.
