  FIG. 5 is an explanatory diagram showing an exemplary aspect of the satellite screen SP displayed on the touch panel monitor 75.

  As shown in the figure, the satellite screen SP of the present embodiment has a mode in which a bet screen BP for voting on the arrival order of the moving body 30 in each race is always displayed on the right side of the display screen. On the left side of the display screen, an explanation screen GP, a pre-race newspaper screen FNP, a live situation screen BCP, a post-race newspaper screen ANP, etc. are displayed at predetermined timings.

  In the voting screen BP according to the present embodiment, a number button BA for designating the number of medals that can be betted for each operation, “single win”, “double win”, “horror”, “horse single”, “wide”, “three” A designation mode button BK for selecting a preferred designation mode from nine types of designation modes of “continuous”, “triple single”, “triple single light” and “heavy win”, and an instruction field BI for explaining a method of specifying the arrival order The bet button BB displaying the horse number, horse name, odds, etc. of the racehorse assigned to each moving body 30 by the main control board 21, and the image image BS of the moving body 30 corresponding to each bet button BB (to the moving body 30) The image of the assigned racehorse and jockey) is displayed, and by operating the bet button BB with either the number button BA or the designation mode button BK selected, the number of the selected number is displayed. It is possible to perform the voting specifying the arrival order at a selected specified manner Dar consideration.

  Here, the “single win” designates the horse number of the racehorse (hereinafter simply referred to as “the first racehorse”, etc.) assigned to the moving body 30 that will be first place, Designates the horse number of the racehorse that will be the first or second place. “Horseren” designates the horse number of the racehorse that falls within the second place as a set. The first and second racehorse horse numbers are designated according to the order of arrival. “Wide” designates any two horse numbers among the first to third racehorses. “Triple Duplex” specifies the horse number combination of the racehorse that will be the first to third place, and “Triple Single” and “Triple Single Light” are the horse number of the racehorse that will be first to third place. The designation is made according to the order of arrival, and “heavy win” designates the arrival order of the racehorses over a plurality of races.

  As described above, the designation order of the arrival order is the same in “triple single” and “triple single light”, but in this designation mode, the probability of winning a vote is low (for example, in the case of 10 heads standing) Is 1/720 on average), so from the player, for example, about 3 to 8 racehorses are designated, and all 3 of them will win if 1 to 3 In many cases, voting is desired in a box that specifies the order of combination. However, in the case of an 8-head box, voting that specifies 336 ways of arrival is required, and even if the consideration of each vote is one medal, medals are required, so many medals are required. Feel free to vote in a box. “Triple single light” is prepared in consideration of such a situation, and accepts voting in the designated form of “triple single” with 0.1 medal as the lowest unit of consideration. . Therefore, the number of medals is 33.6 in the case of voting for each 0.1 medals in the “Triple Single Light” box, but for the convenience of medal processing, etc. The above vote is accepted with 34 medals.

  The voting screen BP shown in FIG. 5 shows a state in which the designation mode of “single” is selected from the designation mode button BK, and the voting method will be described as an example in this case as follows.

  In the initial state in which the “special horse” designation mode is selected from the designation mode button BK, “Please specify one horse” is displayed in the instruction column BI, and the player presses the appropriate number button BA. When you operate the bet button BB of the horse number that you think will be the first place, the instruction field BI will change to "Please specify the second horse", so the bet button of the horse number that you think will be the second place according to this Operate BB. As a result, the voting in the arrival order designated by the operation of the bet button BB is accepted according to the designation manner selected by the designation manner button BK, with the number of medals designated by the number button BA being paid.

  In other designated modes, it is possible to vote in the same manner according to the display in the instruction column BI.

  Voting can be repeated any number of times as long as the remaining time display BT becomes zero, and an arbitrary number of medals that specify a plurality of arrival orders in a plurality of designation modes for one race. It is possible to vote for consideration.

  In the present embodiment, the racehorse of the image image BS performs a predetermined operation every time the bet button BB is operated in order to stimulate the player's interest in voting.

  Specifically, when the bet button BB is pressed and the bet is placed, an image of the racehorse of the corresponding image image BS starts to be displayed is displayed. When the bet is further begun, the horse starts to run in stages. As the jockey makes a guts pose, an image of the horse and jockey shining is displayed.

  Further, in the present embodiment, the horse legs and jockey limbs are moved in the corresponding model portion 37 of the moving body 30 arranged at the start point S1 or S2 in conjunction with the operation of the horse or jockey in the image image BS as described above. Oscillating motion is performed. In this way, since an unprecedented visual reaction occurs with respect to the betting action, it is possible to visually increase the player's interest in voting.

  The explanation screen GP displays an explanation about each designation mode in response to selection of the designation mode button BK. The player can understand the arrival order designation method and the payout characteristics in each designation mode from the explanation screen GP.

  The pre-race newspaper screen FNP is a screen displayed at a timing before the start of each race. In other words, this pre-race newspaper screen FNP provides the player with information useful for predicting the arrival order, such as which of the multiple racehorses that run before each race starts, and assists the player in predicting the arrival order. It can be performed.

  The post-race newspaper screen ANP is a screen displayed at the timing after the end of each race. That is, the post-race newspaper screen ANP provides the player with result information such as how the racehorse that won after the end of each race has won.

  From the information displayed in the pre-race newspaper FNP and the post-race newspaper ANP as described above, the player can learn the name of each racehorse, its results and characteristics, and even beginners can digest the race. In the meantime, it is possible to predict the arrival order more accurately.

  In the pre-race newspaper FNP and the post-race newspaper ANP, it is possible to automatically generate sentences suitable for each race, or automatically select images suitable for each race and display different article contents each time. is there.

  The live situation screen BCP is a screen that is displayed during the execution of each race, and includes a camera image taken by the field camera 22 and the goal camera 23 and a CG image for synthesis (hereinafter, “compositing image”) prepared in advance. ) Or an image to be added to the moving body 30 voted by the player (hereinafter referred to as “additional image”) or the like is displayed as a live image. For the composition image, for example, a running distance, a goal line, or a character for production such as “XX Memorial Cup” can be used. As the additional image, for example, an image such as a coin mark or a pointer indicating the moving body 30 voted by the player can be used. Note that the contents of the composition image and the additional image can be arbitrarily selected according to the setting.

  Returning to FIG. 1, four support members 10 are erected on the side of the apparatus main body 2, and a ring-shaped ceiling member 11 is attached to the upper end thereof. The column member 10 and the ceiling member 11 emit a ceiling camera 25 that captures a bird's-eye view of the track 5 from above, a speaker 26 that outputs sound for various effects such as live broadcasting, fanfare, and BGM, and light emission for various effects. An illumination device 27 and the like are provided.

  In the present embodiment, the track 5 formed on the upper surface plate 4 is disposed below the table portion 74 so that the player sitting on the satellite 70 can look down, and each satellite 70 has The seated player can watch the race with the same feeling as looking down on the track from the gondola seat of an actual racetrack.

  FIG. 6 is an explanatory diagram showing a schematic configuration of hardware of the horse racing game apparatus 1.

  As shown in the figure, in the horse racing game apparatus 1 of the present embodiment, the device main body 2 (central device) includes a main control board 21, each traveling body 40 includes a traveling body control board 61, and each satellite 70 (terminal) Apparatus) includes a satellite control board 71.

  The main control board 21 can transmit and receive data to and from each traveling body control board 61 and each satellite control board 71 by a wiring cable, a wireless LAN line, or the like. The main control board 21, the traveling body control board 61, and the satellite control board 71 are information processing apparatuses each having a storage device that is a storage means such as a CPU, ROM, RAM, and hard disk, although not shown. is there.

  A field camera 22, a goal camera 23, a monitor device 24, a ceiling camera 25, a speaker 26, a lighting device 27, a communication device 28, a wireless LAN device 29, and the like are connected to the main control board 21. The main control board 21 drives and controls these devices in accordance with the progress of the race, and based on the horse data stored in the storage device, traveling data for each traveling body 40 (that is, for each moving body 30). Move information) and determine odds.

  Here, the horse data is composed of data such as names of a plurality of racehorses (horse names) and running ability values that are parameters relating to the strength of the race. The name of the horse may be the same as the actual racehorse, but in this embodiment, each racehorse is original so that players who are not familiar with real racehorses can enjoy the game. The (fictional) horse name is used. The running ability value may be a fixed value for each racehorse regardless of the race, or the running ability value may be determined according to the length of the running course, the weather set for each race, the suitability for the race conditions, etc. By increasing or decreasing, it is possible to increase the diversity of race development for each race. In addition, in order to allow a player who frequently plays with the horse racing game apparatus 1 to make a more appropriate prediction, the running ability value can be increased or decreased according to the past battle record.

  In the horse data, data on the same number of racehorses as the number of moving bodies 30 (for example, 6 to 12) arranged on the track 5 may be recorded, but a larger number (for example, 100 heads) than that may be recorded. If the data about the racehorse is recorded, the race diversity can be enhanced by starting a different racehorse for each race (assigning to the moving body 30).

  Further, the main control board 21 allocates any racehorse recorded as horse data to each moving body 30 arranged on the track 5, and diversifies the running ability value and race development for the assigned racehorse. Traveling data is generated according to an appropriate algorithm using a random number or the like. This running data can specify the position coordinates and direction (angle) of each moving body 30 on the running path 8 with respect to the elapsed time from the start of the race to the goal, and is a predetermined storage device on the main control board 21.

    D12 = {1 / (A1 / AS) × (A2 / (AS−A1))

                  + (A2 / AS) × (A1 / SA-A2))} (2)

  (Camera image data composition processing in the main unit)

  Hereinafter, the camera image data combining process executed in the control of the main control board 21 of the apparatus main body 2 will be described with reference to FIGS. In addition, each process (including the partial process to which the code | symbol is not provided) in the flowchart mentioned later can be changed in order in the range which does not produce contradiction, or can be performed in parallel.

  FIG. 8 is a flowchart showing the flow of the camera image data combining process in this embodiment. The synthesis process shown in FIG. 8 is realized by the apparatus main body 2 executing steps predetermined for the game program loaded in the RAM of the main control board 21 under the control of the CPU of the main control board 21. It should be noted that the camera image data combining process in this embodiment is started by receiving camera image data transmitted from the field camera 22 or the goal camera 23 (hereinafter referred to as “video camera”). This process is repeatedly executed at a frequency at which the video camera captures the moving body 30 traveling on the field and transmits it to the main control board 21, for example, at a frequency of 30 times per second.

  The main control board 21 transmits from the field camera 22 or the goal camera 23 camera image data of the moving body 30 captured by the video camera, and time information indicating the shooting time when the video camera captures the camera image data, respectively. Obtain (S101). The main control board 21 stores the acquired camera image data in a video buffer (see FIG. 10) provided on the main control board 21 (S101).

  Next, the main control board 21 refers to the camera control data 212 stored in the RAM of the main control board 21 on the basis of the acquired time information, and acquires the acquired time information, that is, the time when the camera image data is captured by the video camera. The position information and the like of the video camera is specified (S103). The position information of the video camera is information indicating the position and angle of the video camera on the first traveling surface 4s.

  When the main control board 21 acquires the position information and the like of the video camera, the main control board 21 is predetermined based on the position information and other parameters (for example, the number of driving pulses of the stepping motor that drives the video camera and the dimensions of the mechanism of the video camera). By executing this algorithm, the relative three-dimensional coordinates (3D coordinates) of the video camera in the three-dimensional virtual field space that relatively reproduces the coordinate system of the real space including the field of the horse racing game apparatus 1 are specified. (S105). Note that the three-dimensional coordinates of the video camera can be calculated based on the detected signal by detecting the position and angle of the video camera using an arbitrary sensor. The reference coordinates of the virtual field space can be arbitrarily set.

  In addition, the main control board 21 refers to the traveling data of each moving body 30 generated in advance based on the time information acquired in S101, so that each moving body at the time when the video camera captures the camera image data. The relative three-dimensional coordinates of each moving body 30 in the virtual field space are determined by specifying a position on the field and executing a predetermined viewpoint transformation and perspective transformation based on the identified position of each moving body. (3D coordinates) are specified (S107).

  Next, when the relative 3D coordinates of each moving body 30 are calculated, the main control board 21 generates an object corresponding to each moving body 30, and the generated object is used for each moving body 30 in the virtual field space. It arrange | positions on a relative 3D coordinate (S109) (refer FIG. 10). An object corresponding to each moving body 30 (hereinafter referred to as “moving body object”) is an object having a size capable of accommodating each moving body 30 when each moving body 30 is arranged in a virtual field space. And a simple model such as a cube.

  This moving object can be generated by executing a predetermined algorithm based on the actual size of each moving object 30. For example, in this embodiment, the real scale and the virtual space (CG space) scale are set in advance in the same unit, and the size of the moving object in the virtual space is set based on the size of the real moving object 30. Calculated. According to this, when the actual 1 mm corresponds to one unit in the CG space, the actual moving body 30 fits in a space of 5 cm (horizontal) × 20 cm (length) × 10 cm (height) In this case, an object (object) having a size of 50 × 200 × 100 is generated in the CG space. Note that the shape of the object is not limited to a three-dimensional object, and an arbitrary shape can be adopted as appropriate. This moving object is referred to as determination data when determining whether or not to execute chroma key processing in camera image data composition processing described later.

  The main control board 21 writes the camera image data in an image composition buffer (not shown), and sets a predetermined value (for example, 1) indicating that the image is the background (turf) to the alpha value of the camera image data of each pixel. Write as background information (S111).

  Then, the main control board 21 updates the alpha value of the camera image data of each pixel based on the 3D coordinates of each moving body 30 and the generated moving body object (S111). Specifically, the main control board 21 performs perspective transformation using the 3D coordinates of the video camera calculated in S105 as viewpoint coordinates, and converts the 3D coordinates of the moving object to a two-dimensional plane corresponding to the camera image data. The area of the moving object in the camera image data area is specified by performing coordinate conversion to 2D coordinates. Then, for the pixels included in the area of the moving object in the camera image data, a value indicating that it is included in the area of the moving object (provisional value indicating that it is not the background) (for example, 0) as background information The alpha value is written (S111).

  Thus, in the camera image data, pixels outside the area of the moving object store background information (for example, 1) indicating the background as an alpha value, and pixels within the area of the moving object. In this case, background information (for example, 0) temporarily indicating that it is not the background is stored in the alpha value. The information written in the alpha value is referred to in the camera image data composition process described later. It should be noted that these information regarding the background and the area of the moving object need only be stored in association with each pixel so that they can be referred to.For example, an arbitrary buffer is provided instead of writing to the alpha value, and each pixel and It may be stored in association with each other.

  When the setting of the moving object information for the camera image data is completed, the main control board 21 executes a camera image data composition process (S113).

  FIG. 9 is a flowchart showing a detailed flow of the camera image data synthesis process executed in the present embodiment. The synthesis process shown in FIG. 9 is realized by the CPU of the main control board 21 executing steps predetermined for the game program loaded in the RAM of the main control board 21. In the present embodiment, as an example of the synthesis process, a case where CG image data indicating a goal line and a travel distance is combined with the track 5 on which the moving body 30 travels will be described.

  The main control board 21 performs a composition process for each pixel on the camera image data (S201).

  First, the main control board 21 sets any one pixel, that is, a pixel (hereinafter referred to as a “drawing target pixel”) in which image data for synthesis is to be drawn out of the camera image data. It is determined whether or not it is outside the range of the region, that is, whether or not the drawing target pixel is a pixel located in or near the moving body 30 (S203). The main control board 21 refers to the alpha value of the camera image data of the drawing target pixel, and if the alpha value stores a value indicating that it is outside the range of the moving object, it is outside the range of the moving object. It is determined that there is (S203; Yes).

  When the main control board 21 determines that the drawing target pixel is outside the range of the moving object, 2D perspective transformation is performed on the camera image data of the drawing target pixel with the 3D coordinates of the video camera as the viewpoint coordinates. The CG image data for synthesis is overwritten, and a predetermined value (for example, 0) indicating that it is not the background is written in the alpha value (S209) (see FIG. 10). In the present embodiment, parameters relating to the CG image data for synthesis indicating the goal line and the travel distance are set in advance and stored in a predetermined storage area.

  On the other hand, when a value indicating that the alpha value is within the range of the moving object is stored in the alpha value, the main control board 21 determines that the drawing target pixel is within the range of the moving object (S203; No ), Execute chroma key processing. A known technique can be used for chroma key processing for making a part of an image transparent from a component of a specific color and synthesizing another image there.

  The main control board 21 refers to the color of the camera image data of the drawing target pixel and determines the difference between the color of the camera image data and a predetermined reference color (hereinafter referred to as “chroma key reference color”). It is detected (S205). Here, since the artificial turf material processed with green powder or fiber is spread around the track 5 and its surroundings, the artificial turf material spread on the track 5 is projected as the chroma key reference color. The color data of the obtained image is preset.

  The main control board 21 determines whether or not the detected color difference is within a preset default range (STEP 207), and if it is determined that the detected color difference is within a specified range, Preset synthesis image data is overwritten on the pixel camera image data, and a predetermined value (for example, 0) indicating that it is not the background is written in the alpha value (S209).

  On the other hand, if the main control board 21 determines that the detected color difference is not within the specified range, whether or not the drawing process has been completed for all the pixels without overwriting the synthesis image with respect to the drawing target pixel. Is determined (S211).

  If the drawing process has not been completed for all the pixels, the main control board 21 returns to step 203 and executes the same process (STEP 203 to STEP 209) for the next pixel. When the drawing process is completed for all pixels, the synthesis process is terminated. As a result, a predetermined composition image is combined with the camera image data (see FIG. 10).

  FIG. 11 is a diagram illustrating an example of a combined camera image according to the present embodiment. As shown in the figure, alphanumeric characters such as “GOA (L)” and “200” and a line associated therewith are displayed on the field in which the moving body 30 travels. According to this, the player can easily recognize the position of the goal line on the field and the running distance, so that it is possible to determine the order of arrival of each horse during the race and in the goal. As a result, the player's satisfaction in watching the race can be improved. These images are displayed as a live screen BCP on the monitor device 24 and the touch panel monitor 75 of each satellite 70.

  Returning to FIG. 8, the description will be continued. After completing the image synthesis process, the main control board 21 extracts data of an arbitrary pixel corresponding to the background (turf) from the combined camera image data, and samples color data from the extracted image data (S117). ). The pixel data corresponding to the background is specified by referring to the alpha value of each image. Specifically, only the pixels in which a value indicating the background (for example, 1) is stored as the alpha value are selected as sampling targets. Thereby, sampling of background data can be performed efficiently and appropriately.

  Then, the main control board 21 updates the chroma key reference color by executing a predetermined algorithm using the sampled color data (S117). The updated chroma key reference color is used in the composition process for the next camera image data.

  Next, the main control board 21 executes a predetermined algorithm on the basis of the 3D coordinates of each moving body, whereby each moving body when the moving bodies are arranged on a two-dimensional spatial coordinate system (camera image). The two-dimensional coordinates (2D coordinates) are calculated (S119). Then, the main control board 21 assigns the moving body data (each moving body ID and 2D coordinates) to the header of the combined camera image data and distributes it to the satellite 70 via the communication device 28 (S119).

  (Image display processing in satellite)

  Hereinafter, image data composition / display processing executed in the satellite 70 will be described with reference to FIGS. 12 and 13.

  The image data composition / display process shown in FIG. 12 is realized by the CPU of the satellite control board 71 executing steps predetermined for the game program loaded in the RAM of the satellite control board 71. As a premise of the image data composition / display processing in the satellite 70, the satellite control board 71 receives the voting data of the moving body 30 voted by the player from the bet screen BP on the satellite control board 71 before the game starts. It is stored in a storage area (voting data storage area).

  When the game is started, the satellite control board 71 of the satellite 70 receives the combined camera image data and moving body data from the apparatus main body 2 via the communication device 79 (S301).

  The satellite control board 71 extracts the moving body ID and 2D coordinates from the received moving body data (S303), and identifies the moving body ID that matches the moving body ID included in the voting data (S305).

  When the mobile object ID is specified, the satellite control board 71 combines additional data set in advance with the combined camera image data based on the 2D coordinates of the specified mobile object ID (S307). The additional data is, for example, a coin mark for distinguishing the mobile body 30 voted by the player from other mobile bodies 30 and is synthesized so as to be arranged in the vicinity of the mobile body 30 voted by the player. Such additional data may be arranged so that the mobile body 30 voted by the player can be identified from other mobile bodies 30, and may be a pointer or character information in addition to a coin mark. Moreover, it is desirable to arrange | position near the circumference | surroundings of the mobile body 30 according to the driving | running | working conditions of the movement 30 etc., and although typically added to the upper part of the mobile body 30, it is not restricted to this. Note that the additional data is not synthesized when the mobile body 30 voted by the player is not included in the camera image due to running behind the top mobile body 30 or the like.

  The satellite control board 71 outputs the combined camera image data obtained by combining the additional data to the touch panel monitor 75 (S309).

  FIG. 13 is an example of a screen output to the touch panel monitor 75.

  As shown in the figure, it can be seen that a coin mark C is displayed above the top horse running in the corner. According to this, the player can instantly identify the moving body 30 that he / she voted from among the moving moving bodies 30, so that he / she can more enjoy watching the race. The additional data is synthesized based on the player's voting data in each satellite 70, so that the camera image of the moving body 30 finally displayed on the satellite 70 depends on the voting status of the player. Will be different.

  As described above, according to the above-described embodiment, the apparatus main body 2 synthesizes and displays a CG image such as a running distance and a goal line on the camera image captured by the video camera. It is possible to easily determine the arrival order of each horse in the goal.

  In addition, according to the above-described embodiment, the mobile body data including the position of the mobile body 30 is distributed to each satellite 70 together with the camera image data in which the synthesis image is combined. Therefore, each satellite 70 is included in the player's voting data. A unique image can be generated and displayed. For example, since a coin mark is displayed in the vicinity of the mobile body 30 voted by the player, the player can instantly identify the mobile body 30 voted by the player.

  Further, according to the above-described embodiment, since the chroma key process is performed only in the range included in the area of the moving object in the camera image data synthesis process, the target area of the chroma key process is minimized, the surface deterioration of the field, etc. As a result, it becomes possible to prevent a situation in which correct chroma key processing cannot be performed.

  Further, according to the above embodiment, the chroma key reference color is dynamically updated by sampling the color from the pixel data outside the area of the moving object, so that the chroma key process can be performed even when the indoor condition or lighting conditions change. Can be executed normally.
