Next, the internal configuration of the controller 7 will be described with reference to FIG. FIG. 6 is a block diagram showing the configuration of the controller 7.
In FIG. 6, the core unit 70 includes a communication unit 75, an acceleration sensor 701, and a vibrator 704 in addition to the operation unit 72 and the imaging information calculation unit 74 described above.

  The imaging information calculation unit 74 includes an infrared filter 741, a lens 742, an imaging element 743, and an image processing circuit 744. The infrared filter 741 allows only infrared light to pass through from light incident from the front of the core unit 70. The lens 742 condenses the infrared light that has passed through the infrared filter 741 and outputs the condensed infrared light to the image sensor 743. The imaging element 743 is a solid-state imaging element such as a CMOS sensor or a CCD, for example, and images the infrared rays collected by the lens 742. Therefore, the image sensor 743 captures only the infrared light that has passed through the infrared filter 741 and generates image data. Image data generated by the image sensor 743 is processed by an image processing circuit 744. Specifically, the image processing circuit 744 processes the image data obtained from the image sensor 743 to detect high-luminance portions, and transmits processing result data indicating the result of detecting their position coordinates and area to the communication unit 75. Output to. The imaging information calculation unit 74 is fixed to the housing 71 of the core unit 70, and the imaging direction can be changed by changing the direction of the housing 71 itself. However, since the housing 71 is connected to the subunit 76 by a flexible connecting cable 79, the imaging direction of the imaging information calculation unit 74 does not change even if the direction or position of the subunit 76 is changed. . Although details will be described later, a signal according to the position and movement of the core unit 70 can be obtained based on the processing result data output from the imaging information calculation unit 74.

  The acceleration sensor 701 is an acceleration sensor that detects acceleration along three axes of the core unit 70 in the vertical direction, the horizontal direction, and the front-rear direction. The acceleration sensor 701 may be an acceleration sensor that detects acceleration on two axes in the vertical direction and the horizontal direction depending on the type of operation signal required. Data indicating the acceleration detected by the acceleration sensor 701 is output to the communication unit 75. The acceleration sensor 701 is typically a capacitance type acceleration sensor, but other types of acceleration sensors or gyro sensors may be used. Based on the acceleration data output from the acceleration sensor 701, the movement of the core unit 70 can be detected.

  The communication unit 75 includes a microcomputer (microcomputer) 751, a memory 752, a wireless module 753, and an antenna 754. The microcomputer 751 controls the wireless module 753 that wirelessly transmits transmission data while using the memory 752 as a storage area during processing.

  An operation signal (core key data) from the operation unit 72 provided in the core unit 70, an acceleration signal (acceleration data) from the acceleration sensor 701, and processing result data from the imaging information calculation unit 74 are output to the microcomputer 751. The In addition, an operation signal (sub key data) from the operation unit 78 provided in the subunit 76 is output to the microcomputer 751 via the connection cable 79. The microcomputer 751 temporarily stores the input data (core key data, sub key data, acceleration data, and processing result data) in the memory 752 as transmission data to be transmitted to the receiving unit 36a.

  Here, the wireless transmission from the communication unit 75 to the receiving unit 36a is performed every predetermined cycle, but since the game processing is generally performed in units of 1/60, a shorter cycle than that is performed. It is necessary to send in. Specifically, the processing unit of the game is 16.7 ms (1/60 seconds), and the transmission interval of the communication unit 75 configured with Bluetooth is 5 ms. When the transmission timing to the receiving unit 36a comes, the microcomputer 751 outputs the transmission data stored in the memory 752 as a series of operation information and outputs it to the wireless module 753. The wireless module 753 radiates operation information from the antenna 754 as a radio wave signal using a carrier wave of a predetermined frequency using, for example, Bluetooth (registered trademark) technology.

  That is, core key data from the operation unit 72 provided in the core unit 70, subkey data from the operation unit 78 provided in the subunit 76, acceleration data from the acceleration sensor 701, and processing from the imaging information calculation unit 74. Result data is transmitted from the core unit 70. Then, the radio signal is received by the receiving unit 36a of the game apparatus 3, and the radio signal is demodulated or decoded by the game apparatus 3, whereby a series of operation information (core key data, sub key data, acceleration data, and processing result data). ) To get. And CPU30 of the game device 3 performs a game process based on the acquired operation information and a game program. When the communication unit 75 is configured using the Bluetooth (registered trademark) technology, the communication unit 75 can also have a function of receiving transmission data wirelessly transmitted from other devices.

  The vibrator 704 may be a vibration motor or a solenoid, for example. Since the vibration is generated in the core unit 70 by the operation of the vibrator 704, the vibration is transmitted to the hand of the player holding it, and a so-called vibration-compatible game can be realized.

  As shown in FIG. 7, in order to play a game using the controller 7 in the game system 1, the player holds the core unit 70 with one hand (for example, the right hand) (see FIG. 8), The subunit 76 is grasped with a hand (for example, the left hand). Then, the player holds the core unit 70 so that the front surface of the core unit 70 (the incident side of the light imaged by the imaging information calculation unit 74) faces the monitor 2. On the other hand, near the display screen of the monitor 2, two LED modules 8L and 8R are installed. These LED modules 8L and 8R each output infrared light toward the front of the monitor 2.

  When the player holds the core unit 70 so that the front surface thereof faces the monitor 2, infrared light output from the two LED modules 8 </ b> L and 8 </ b> R enters the imaging information calculation unit 74. Then, the imaging device 743 captures the incident infrared light through the infrared filter 741 and the lens 742, and the image processing circuit 744 processes the captured image. Here, the imaging information calculation unit 74 detects the infrared component output from the LED modules 8L and 8R, thereby acquiring the position (position of the target image) and area information of the LED modules 8L and 8R in the captured image. To do. Specifically, the image processing circuit 744 analyzes the image data captured by the image sensor 743, first excludes images that cannot be infrared light from the LED modules 8L and 8R from the area information, and further increases the luminance. The high point is determined as the position of each of the LED modules 8L and 8R.

  Then, the imaging information calculation unit 74 acquires position information such as the barycentric position of the determined bright spots and outputs it as the processing result data. Here, the position information as the processing result data may be output as a coordinate value with a predetermined reference point in the captured image (for example, the center or upper left corner of the captured image) as the origin, and a bright spot at a predetermined timing The position may be used as a reference point, and the difference in the current bright spot position from the reference position may be output as a vector.

  That is, the position information of the target image is a parameter used as a difference with respect to the reference point when a predetermined reference point is set for the captured image captured by the image sensor 743. By transmitting such processing result data to the game apparatus 3, the game apparatus 3 moves the imaging information calculation unit 74, that is, the core unit 70, with respect to the LED modules 8L and 8R based on the difference in the position information from the reference. The change amount of the signal according to the posture, position, etc. can be obtained. Specifically, since the position of the high luminance point in the image transmitted from the communication unit 75 changes when the core unit 70 is moved, direction input and coordinate input corresponding to the change in the position of the high luminance point are performed. By performing the above, direction input and coordinate input along the moving direction of the core unit 70 can be performed. In the game processing operation example to be described later, an example is used in which the imaging information calculation unit 74 acquires the coordinates of the center of gravity of each of the target images of the LED modules 8L and 8R in the captured image and outputs it as the processing result data.

  In this manner, the imaging information calculation unit 74 of the core unit 70 images the marker (infrared light from the two LED modules 8L and 8R) fixedly installed in the game apparatus 3 by imaging. In the game process, by processing the data output from the core unit 70, an operation corresponding to the movement, posture, position, etc. of the controller becomes possible, and the intuition that is different from the operation buttons and operation keys that press the buttons is different. Operation input. Further, as described above, since the marker is installed in the vicinity of the display screen of the monitor 2, it is easy to convert the position relative to the marker into the movement, posture, position, etc. of the core unit 70 relative to the display screen of the monitor 2. It can be carried out. That is, the processing result data based on the movement, posture, position, etc. of the core unit 70 can be used as an operation input that directly acts on the display screen of the monitor 2.

  With reference to FIG. 8, a state in which the player holds the core unit 70 with one hand will be described. FIG. 8A is an example of a state where the player holds the core unit 70 with the right hand as viewed from the front side of the core unit 70. FIG. 8B is an example of a state in which the player holds the core unit 70 with the right hand as viewed from the left side of the core unit 70.

  As shown in FIG. 8, the core unit 70 has a size that can be gripped with one hand of an adult or a child as a whole. When the player's thumb is attached to the upper surface of the core unit 70 (for example, in the vicinity of the cross key 72a) and the player's index finger is attached to the concave portion (for example, in the vicinity of the operation button 72i) of the core unit 70, the core unit 70 The light incident port of the imaging information calculation unit 74 provided in front of the player is exposed in the forward direction of the player. Needless to say, such a gripping state with respect to the core unit 70 can be similarly performed even with the left hand of the player.

  As described above, the core unit 70 can easily operate the operation unit 72 such as the cross key 72a and the operation button 72i while the player holds it with one hand. Furthermore, when the player holds the core unit 70 with one hand, the light incident port of the imaging information calculation unit 74 provided on the front surface of the core unit 70 is exposed, so that the two LED modules 8L and 8R described above Infrared light can be easily taken from the light entrance. That is, the player can hold the core unit 70 with one hand without hindering the function of the imaging information calculation unit 74 of the core unit 70. That is, when the player moves the hand holding the core unit 70 with respect to the display screen, the core unit 70 can further include an operation input in which the movement of the player's hand acts directly on the display screen.

  Here, as shown in FIG. 9, each of the LED modules 8L and 8R has a viewing angle θ1. Further, the image sensor 743 has a viewing angle θ2. For example, the viewing angles θ1 of the LED modules 8L and 8R are both 34 ° (half-value angle), and the viewing angle θ2 of the image sensor 743 is 41 °. When both the LED modules 8L and 8R exist in the viewing angle θ2 of the imaging device 743, and the imaging device 743 exists in the viewing angle θ1 of the LED module 8L and in the viewing angle θ1 of the LED module 8R. The game apparatus 3 detects the position of the core unit 70 by using the position data regarding the high luminance point by the two LED modules 8L and 8R.

  On the other hand, when there is only one LED module 8L or 8R in the viewing angle θ2 of the imaging device 743, or in either one of the viewing angle θ1 of the LED module 8L or the viewing angle θ1 of the LED module 8R. When 743 exists, the position of the core unit 70 is detected using the position data regarding the high-luminance point by only one of the two LED modules 8L and 8R.

  Here, a gun shooting game executed in the game system having the above-described configuration will be described. A player operates the main character using the controller 7. The main character completes the mission by defeating the enemy with other weapons such as guns and knives. For example, in a game called Biohazard (registered trademark), in order to solve a bizarre incident that occurred in a virtual city, the main character who went to the city solved the mystery while being attacked by mysterious monsters and residents. In the story of escaping from the city, the main character uses items such as guns and knives to defeat monsters and inhabitants (enemy characters), or breaks boxes (objects) to search for objects.

  FIGS. 10 and 11 are flowcharts showing the main character motion control process in the gun shooting game. 12 to 14 are diagrams showing one scene of the gun shooting game.

  In the following description of the game, the number of bullets that can be fired, which is the number of bullets loaded in the gun, and the number of stock bullets, which is the number of bullets that the main character has as a reserve, are stored in the main memory 33. .

  FIG. 10A shows an operation for determining whether or not the B button (button switch 72i) is turned on. This operation is periodically executed every short time (for example, several tens of milliseconds). It is determined whether or not the B button is currently turned on (S10). If it is turned on (YES in S10), the main character in a posture with a gun is drawn and output (S11). Then, the gun is aimed in the direction indicated by the core unit 70 of the controller 7 (see FIG. 7) (S12). On the other hand, if the B button is not turned on (NO in S10), a main character in a normal posture without a gun is drawn and output (S13). Then, the character is directed in the direction indicated by the controller (S14).

  FIG. 12 shows an example of the game screen including the main character in the posture with the gun output in S11. In this figure, the circle displayed slightly from the center right is the aiming position.

  FIG. 5B is a flowchart showing processing operations executed when the A button (button switch 72d) is turned on. When the A button is turned on (S20), this process is executed in an event-driven manner. At this time, it is determined whether or not the B button is turned on, that is, whether or not the main character is in a posture with a gun (S21). If the main character is holding a gun (YES in S21), then a bullet is fired in the direction in which the aim is aimed and the target is destroyed (S22). At this time, a signal indicating that a bullet has been fired is transmitted from the game apparatus body 3 to the controller 7. The controller 7 drives the vibrator 704 and transmits the impact of firing the bullet to the player's hand as vibration. Then, 1 is subtracted from the number of bullets that can be fired (S23).

  On the other hand, when the B button is not turned on and the main character does not hold a gun (NO in S21), if the A button is turned on, another action selected at that time is executed ( S24). Other actions include flying and throwing.

  FIG. 11A is a flowchart showing a processing operation executed when a swing of the core unit 70 (a swinging operation at a predetermined speed or more) is detected. When it is detected that the core unit 70 is swung (swinged) at a predetermined speed or higher (S30), this process is executed in an event-driven manner. At this time, it is determined whether or not the B button is turned on, that is, whether the main character is in a posture with a gun (S31). If the main character is holding a gun (YES in S31), a bullet reload operation for that gun is executed (S32). This reloading operation will be described in detail with reference to the flowchart of FIG. On the other hand, when the B button is not turned on and the main character does not hold a gun (NO in S31) and the core unit 70 is swung, the main character shook the knife (search knife). Then, it draws and outputs an image that destroys the nearby target (S33).

  FIG. 14 shows an image when the main character output in S33 shakes the knife. FIG. 4A is an image before the knife is shaken (the moment when the swing is detected), and FIG. 4B is an image after the swing of the knife. In this game, the knife drawn out by the swing of the core unit 70 is a search knife, and the knife is a target (enemy character or object) on the game screen, regardless of which direction the player swings. It is paid out for.

  FIG. 11B is a flowchart showing the reloading operation. As described above, this operation is executed when the core unit 70 is swung while the B button is turned on and the main character is holding a gun.

  First, whether or not the maximum number of bullets that can be set in the gun is the maximum value, that is, whether or not there is an empty magazine in the gun (S40), and whether or not the number of reserve stock bullets is zero (S41). to decide. If the magazine is empty (S40 YES) and the number of stock bullets is not 0 (S41 YES), the operation from S42 onward is executed. On the other hand, if there is no space in the magazine (NO in S40) or if the number of stock bullets is 0 (NO in S41), the bullets cannot be reloaded, and the operation is terminated as it is.

  In S42, the main character is made to perform a reloading (reloading) operation of taking out the magazine from the gun grip and setting the magazine again as shown in FIGS. 13A and 13B (S42). At the same time, a reload sound effect (for example, a voice “gachatsu”) is generated. Then, the number of empty magazines and the number of stock bullets are compared (S43). If there are more stock bullets than the number of empty magazines (YES in S43), the bullets are loaded by the number of empty magazines (S44). . That is, the number of bullets that can be fired is increased to the maximum value. On the other hand, if the number of stock bullets is less than the available number (NO in S43), all stock bullets are loaded into the magazine (S45). That is, the number of bullets that can be fired is increased by the number of stock bullets. After that, the stock ammunition number register is subtracted by the loaded number (S46), and the operation is terminated.

  In the invention of claim 3, the character carrying the gun appears in the image output to the monitor, and the character is set to fire the gun in the image (game). In the invention, it is not indispensable that the character appears in the image, and includes a setting in which the player himself does not appear and fires a (virtual) gun. That is, the present invention can be applied to a gun shooting game in which a main character does not appear, and the present invention may be applied to a game in which a player himself fires a gun and hits a target. In any case, the player can reload the virtual gun by swinging the controller. This swinging operation is similar to the operation of taking out the magazine by hitting the grip of a short gun held in the right hand with the left hand, so that the player can reload the gun in the mood of operating the gun.

  FIG. 13 shows an example of a game screen including a figure in which the main character drawn and output in S42 reloads bullets in the gun. FIG. 4A shows the magazine being removed from the gun grip. FIG. 5B shows a state where the magazine is remounted. Thus, by removing the magazine from the gun and mounting it again, the player can know that the bullet has been reloaded.

  The bullets to be loaded on the gun can be obtained by purchasing the main character at a store in the game, finding it hidden, picking up a fallen item, or the like.

  When playing this gun shooting game, the subunit may be used for movement control of the main character.

  Further, the present invention may be applied not only to a home game machine but also to an arcade game machine. Further, the present invention may be applied not only to a game machine in which the game machine main body and the controller are separated but also to a portable game machine in which the controller and the apparatus main body are integrated.

  In the above-described embodiment, it is possible to reload the bullet and swing the search knife regardless of which direction the core unit 70 is swung, but this is for causing the main character to reload the bullet or swing the knife. The swing direction of the core unit 70 may be limited. Alternatively, the player may behave differently for each main character by swinging the core unit 70 in different directions. For example, if the core unit 70 is swung in the horizontal direction, the main character is reloaded with bullets, and if the core unit 70 is swung in the vertical direction, the main character is swung with a knife.
