[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a game system using a position indicating device capable of indicating an arbitrary position on a screen of a display device, and an information storage medium used in the game system.
[0002]
[Background Art and Problems to be Solved by the Invention]
2. Description of the Related Art Conventionally, there has been known a game system in which shooting is aimed at a target displayed on a screen using a position pointing device capable of pointing to an arbitrary position on the screen at a position away from the screen of the display device. . As a position indicating device in such a game system, for example, there is a light transmission type controller such as a gun-type controller.
[0003]
When the player (user) pulls the trigger of the gun-type controller, the position on the screen of the display device indicated by the gun-type controller is detected. When the target is present at this detection position, it is determined that it is a hit (hit), and when it is not present, it is determined that it is a miss (miss). This allows the player to experience a virtual shooting of shooting a target without using a real gun.
[0004]
By the way, in such a game system, a player uses a gun-type controller with one hand or both hands to perform a virtual shooting experience. However, when a player selects a command or item during a shooting game as in other game fields such as role-playing and adventure games, the operability is significantly degraded.
[0005]
Thus, various proposals have been made on techniques for improving the operability of such a gun-type controller.
[0006]
For example, Japanese Patent Application Laid-Open No. 11-319316, “Indicated Position Detection Method and Device” discloses a technique of incorporating a cross direction key into a gun-type controller in which an artificial retina unit is provided at the tip of a barrel part. The gun-type controller captures a game image displayed on the display device by an artificial retina unit provided at the tip of the barrel portion, and extracts an edge frame of the game image from the captured image. Further, for example, the relative position of the edge frame with respect to the captured image is detected on the basis of the center position of the captured image that is the position indicated by the gun-type controller, thereby detecting the position indicated in the game image by the gun-type controller.
[0007]
Also, with this gun-type controller, for example, by operating the trigger with the index finger and operating the cross direction key with the thumb, the movement of the character operated by the player, the change of the placement of the enemy character, Complex operations such as selecting a weapon to be used are facilitated.
[0008]
Furthermore, for example, Japanese Patent Application Laid-Open No. 5-172495 “Light Gun Toy” discloses a technique related to a gun-type controller that makes a hit determination by emitting a laser beam and detecting return light reflected by a target. ing. This gun-type controller emits laser light to the intersection of the X axis and Y axis that are orthogonal to each other, and the aim can be determined by adjusting the X axis and Y axis with the cross direction key. it can. As a result, it is possible to perform fine aim adjustment without releasing the hand from the controller.
[0009]
However, in the game system using the conventional gun-type controller described above, the player cannot freely enlarge or reduce the image near the target object. For this reason, in the game where the virtual object such as the sniper of the target object is experienced, the virtual reality of the player cannot be improved.
[0010]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a position indicating device capable of indicating operation data of operation means by a player and an arbitrary position on the screen of the display device.

It can be realized by hardware such as a magnetic tape or a memory (ROM). The processing unit 100 performs various processes of the present invention (this embodiment) based on information stored in the information storage medium 180. That is, the information storage medium 180 stores information (program or data) for executing (implementing) the means of the present invention (this embodiment).
[0036]
The program or data for executing the means of the present invention (this embodiment) may be distributed from the information storage medium of the host device (server) to the information storage medium 180 via the network. Use of such an information storage medium of the host device (server) is also included in the scope of the present invention.
[0037]
The gun-type controller 10 includes an indicator 12 (casing) formed in the shape of a gun, a trigger 14 provided on a grip portion of the indicator 12, and a vicinity of a muzzle 15 (light entrance) of the indicator 12. An optical circuit comprising a lens 16 and an optical sensor 18 incorporated in the controller, a controller processing unit 20 for controlling the entire gun-type controller and calculating a designated position, and a cross for inputting different operation data depending on the operation direction. An operation data input unit 21 including direction keys and a communication unit 30 functioning as an interface between the processing unit 100 are included.
[0038]
Here, the gun-type controller 10 can be gripped, and the trigger-type controller 14 and an operation data input unit 21 that is a cross-direction key are arranged at a position where the player can operate with one hand. It is desirable that Furthermore, it is desirable that the cross direction key of the operation data input unit 21 can be operated with one finger of the player. For example, the player can further improve the operability by triggering the trigger 14 with the index finger and operating the cross direction key with the thumb of the same hand.
[0039]
The processing unit 100 includes a game information generation unit 102, a position determination unit 104, an operation data processing unit 106, and a zoom processing unit 108.
[0040]
The game information generation unit 102 displays game information such as a game image (image viewed from a given viewpoint in the object space in a three-dimensional game) and game sound (BGM, sound effect, or sound) according to the result of the game process. It is generated and output to the display unit (display device) 190 and the sound output unit 192.
[0041]
The position determination unit 104 determines whether or not the object displayed on the display unit according to the game process is present at the indicated position (or the trajectory line (in a broad sense, a line passing through the indicated position)) of the gun-type controller 10. In this way, hit determination is performed.
[0042]
When the object is expressed in two dimensions, the object can be specified by whether or not the object exists at the indicated position on the display unit.
[0043]
Further, when the object is expressed in three dimensions, for example, a trajectory line specified by the indicated position on the display unit (in a broad sense, a line passing through the indicated position) is obtained, and whether or not the object exists on the trajectory line. The object can be specified by More specifically, it can be specified by an intersection check between a ballistic line and a simple object containing the object.
[0044]
The operation data processing unit 106 determines the content of the operation data from the gun-type controller that is appropriately input by the player during the game process, and the determined content for the object specified by the indicated position of the gun-type controller in the game process Reflect.
[0045]
The zoom processing unit 108 enlarges or reduces the image displayed on the display unit 190 according to the indicated position of the gun-type controller 10 and the operation data from the player determined by the operation data processing unit 21.
[0046]
More specifically, when the player designates an arbitrary position of the display unit 190 by using the gun-type controller 10, the zoom processing unit 108 uses the operation data from the operation data input unit 21 when the object is expressed in three dimensions. Accordingly, zoom control is performed to widen or narrow the angle of view for the game image specified by the designated position.
[0047]
When the object is expressed in two dimensions, the game image specified by the designated position is zoomed so as to change the scaling of the two-dimensional display data according to the operation data from the operation data input unit 21. Take control.
[0048]
In this way, by performing zoom control of the image near the designated position of the gun-type controller 10, for example, the real thrill of shooting aiming at a target can be experienced more realistically.
[0049]
The zoom processing unit 108 may linearly widen or narrow the angle of view of the image to be controlled for the zoom control. However, the zoom processing unit 108 determines the control target step by step according to input of operation data. The angle of view of the resulting image (the distance between the viewpoint and the screen) may be increased or decreased.
[0050]
Here, the image enlarged or reduced by the zoom processing unit 108 is displayed on the display unit 190, but is provided separately from another screen (such as a window screen) displayed on the display unit 190 or the display unit 190. You may make it display on other display parts, or display parts, such as LCD (liquid crystal display) provided in the gun-type controller 10 which a player operates.
[0051]
Note that the functions of the controller processing unit 20 and the communication unit 30 may be realized by hardware such as ASIC, or may be realized by a combination of various processors and software.
[0052]
Next, an outline of the operation of the game system of FIG. 1 will be described.
[0053]
First, the processing unit 100 generates a video signal, and the picture tube of the display unit 190 performs a light emission operation based on the generated video signal. Thereby, an object such as a target object (enemy character) is displayed on the screen of the display unit 190.
[0054]
Next, when the player aims the target object on the screen and points the muzzle 15 of the gun-type controller 10 toward the display unit 190 and pulls the trigger 14, the screen flashes. When the raster scanning of the display unit 190 passes through the detection area 191 set near the indicated position of the gun-type controller 10, the scanning light at that time is condensed on the optical sensor 18 by the lens 16. Thereby, the optical sensor 18 outputs a light detection signal.
[0055]
Then, the position calculation unit 22 of the controller processing unit 20 that has received this light detection signal calculates the indicated position (X, Y coordinates) of the gun-type controller 10. At this time, the position calculation unit 22 uses the synchronization signal included in the video signal from the processing unit 100 to calculate the indicated position of the gun-type controller 10.
[0056]
Then, the calculated information on the indicated position is transferred to the processing unit 100. Based on the indicated position information, the processing unit 100 performs a hit check with the target object displayed on the screen. That is, it is determined that a virtual shot from the gun-type controller 10 has hit the target object when the indicated position matches the position of the target object.
[0057]
In the game system of this embodiment, the operation data input from the operation data input unit 21 of the gun-type controller 10 is also transferred to the processing unit 100 via the communication unit 30 in the same manner as the indicated position information described above.
[0058]
The operation data processing unit 106 of the processing unit 100 determines the content of the transferred operation data and reflects it in the game process. For example, when the game realized by the present embodiment is a shooting game, it is assumed that the transferred operation data instructs zoom-in that means image enlargement. At this time, the angle of view of the image near the indicated position on the display unit 190 of the gun-type controller 10 operated by the player is narrowed by a given control amount only while operation data for instructing zoom-in is input. An enlarged image is displayed on the display unit 190.
[0059]
When the trigger 14 of the gun-type controller 10 is pulled by the player, a shot (bullet) is fired to the object specified by the aiming position that is the indicated position. The game process is performed so that the character of the object hit by this shot receives a given damage.
[0060]
Note that the game system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, and not only such a single player mode but also a multiplayer mode in which a plurality of players can play. A system may be provided.
[0061]
Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated using a plurality of terminals.
[0062]
2. Features of this embodiment
Next, a shooting game realized by this embodiment will be described.
[0063]
In this shooting game, in a virtual space where various objects are represented in three dimensions, a character operated by a player defeats one after another while shooting aiming at an enemy character (target object) standing in a building. .
[0064]
In FIG. 2, an example of the game image for demonstrating the game system implement | achieved by this embodiment is shown.
[0065]
In the game system realized by the present embodiment, the appearance of a building in which an enemy character is hidden is displayed on the display unit 200. The player can enlarge (zoom in) or reduce (zoom out) an image near an arbitrary position indication of the displayed building by inputting operation data via the operation data input unit 21 of the gun-type controller 10. It can be done. Here, the enemy character 206 lurking in the window 204 on the top floor of the building 202 is displayed on the display unit 200 in a state where the image is enlarged to some extent by the player.
[0066]
Regardless of the zoom control via the operation data input unit 21, the player pulls the trigger 14 at any time when the aim is aimed at the target target 208 (in the broad sense, a shot). Can be fired. Here, the bullet means a shot including a missile, a laser, a bazooka, and the like.
[0067]
When the bullet fired by the player pulling the trigger 14 hits the enemy character, the enemy character is damaged corresponding to the power of the bullet. On the other hand, the character operated by the player also receives damage corresponding to the bullet fired by the enemy character.
[0068]
Furthermore, the operation data input unit 21 provided in the gun-type controller 10 of the game system according to the present embodiment includes a cross direction key. The cross direction key can input different operation data depending on the operation direction.
[0069]
In the present embodiment, the cross direction key as the operation data input unit 21 inputs zoom control data for instructing enlargement and reduction of an image near the indicated position of the gun-type controller 10 in two directions. Assigned as input means.
[0070]
The remaining direction keys are assigned a switching command for switching between an infrared camera for discriminating enemy characters lurking in the dark and thermography that can be displayed in stages according to heat. Through these special cameras, the player can recognize and shoot enemy characters that cannot be identified with a normal scope.
[0071]
As described above, in this embodiment, the gun-type controller 10 is provided with the operation data input unit 21 including the cross direction keys, so that an image near the designated position of the gun-type controller 10 according to the operation data from the operation data input unit 21. Can be arbitrarily enlarged or reduced. Furthermore, by assigning other command inputs to the other direction keys of the cross direction key so that the player can quickly perform complicated operations, it becomes possible to develop more complicated game content than before. .
[0072]
Such a game system can realize various types of games, but has the following characteristics.
[0073]
(1) Zoom control
The game system realized by the present embodiment corresponds to the operation content of the operation data input unit 21 based on the indicated position in the screen by the gun-type controller 10 (position indicating device) that can indicate an arbitrary position in the screen. The zoom control can be performed.
[0074]
Here, the zoom control based on the designated position in the screen by the gun-type controller 10 means that the angle of view is controlled with respect to the image near the designated position detected by the gun-type controller 10 as shown in FIG. (Control of the distance between the viewpoint and the screen). When the object is expressed in two dimensions, this means that scaling control is performed on an image near the designated position.
[0075]
Further, the zoom control corresponding to the operation content of the operation data input unit 21 means that the player enlarges or reduces the image displayed on the display unit 190 based on the operation data via the operation data input unit 21. That means.
[0076]
More specifically, the operation data input from the player via the operation data input unit 21 with the image near the position indicated by the gun-type controller 10 as the point of sight (center) at a position away from the screen as in a shooting game. The image is enlarged or reduced according to the above. When the object is expressed in three dimensions, the image is zoomed out or zoomed in by widening or narrowing the angle of view.
[0077]
As a result, in the past, a predetermined image was enlarged or reduced at a predetermined location, or an image specified by a player's designated position was only enlarged at a predetermined magnification. It is possible to give a degree of freedom to greatly change the progress of the game according to the instruction status, and increase the fun of the game.
[0078]
Furthermore, since the cross direction key is provided as the operation data input unit 21 provided in the gun-type controller 10, the above-described designation of an arbitrary position in the screen and zoom control can be performed only with one hand having a controller. The complicated operations described above can be performed quickly.
[0079]
Here, zoom control of an image near the designated position of the gun-type controller 10 is performed, but zoom control of an image near a predetermined position may be performed. For example, in the “mission selection screen” in which a plurality of missions before the game can be selected, a mission arbitrarily selected by the player is used as a start trigger, and the zoom-in control of the image predetermined in the mission is used. Is possible.
[0080]
In the shooting game realized by the present embodiment, in the image enlarged or reduced by the cross-direction key that is the operation data input unit 21 in this way, the player becomes an object specified by the indicated position of the gun-type controller 10. On the other hand, a shot is shot.
[0081]
(2) Command input
In addition, the game system realized by the present embodiment assigns another command other than the zoom control described above to the cross direction key as the operation data input unit 21 provided in the gun-type controller 10, thereby allowing more complicated operations. It is characterized by making it easy.
[0082]
Here, another command other than the zoom control is a command provided to increase variations in the story development of the game. For example, the game image for the player who views the screen of the display device such as the brightness and saturation of the image. Effects of game images that change the appearance of the image, the direction of the virtual camera and the direction of the line of sight of the character (object) operated by the player, such as the type of shot (bullet), the type of weapon, and the type of game The type of attack method that requires operations other than zoom control in real time, the power of the attack, or a command for switching items.
[0083]
In the shooting game of the present embodiment, these commands are assigned as commands for switching the enemy character aiming method between the infrared camera and the thermography.
[0084]
FIG. 3 shows an example of assignment of special weapons for each direction key of the operation data input unit 21 in the present embodiment.
[0085]
The cross direction key of the operation data input unit 21 generates different types of operation data by pressing each direction. Here, four directions of an up direction key 210, a down direction key 212, a left direction key 214, and a right direction key 216 can be pressed, and four types of operation data are generated.
[0086]
In the shooting game of the present embodiment, the up key 210 is zoomed in, the down key 212 is zoomed out, the left key 214 is a thermographic aim switching command, and the right key 216 is an infrared camera aim switching command. Assigned.
[0087]
For example, the player depresses the up key 210 of the operation data input unit 21 to zoom in on the image near the designated position, depresses the right direction key 216, and determines an enemy character hidden in the dark by the infrared camera, and then triggers By pulling 14, a shot (bullet) can be fired at the aiming position. If an object exists on the ballistic line specified by the indicated position at the time of launch, it is determined that the object is hit and the object receives a given amount of damage.
[0088]
FIGS. 4A and 4B and FIGS. 5A to 5C show examples of game images when zoom control is performed in the present embodiment.
[0089]
In the game system realized by this embodiment, in order to compete for the target search technology and the aiming technology, timing is started at the start of the game, and the game is so scored as to hit the target at the earliest possible time. The result is reflected.
[0090]
When the game is started, for example, the TIME of the initial value “90” is subtracted by “1” every predetermined time interval. The game screen 220 displays a time display screen 222 and a zoom rate display screen 224 that indicates the degree of enlargement or reduction of the image at that time. As an initial state, it is assumed that TIME is “90” and the zoom rate is “× 10”.
[0091]
The player instructs the position (position 226) of the portion where the enemy character that is the target is lurking at the start of the game, and the operation data input unit 21 of the gun-type controller 10, as shown in FIG. Press the direction key.
[0092]
Then, as shown in FIG. 4B, the image is enlarged with the vicinity of the designated position as the center. Here, although the remaining time is reduced to “88”, it is determined that the target character 228 is in the window 230 by setting the zoom rate to “× 40”.
[0093]
When the player wants to hit the enemy character 228 more reliably, the player further presses the upward key of the operation data input unit 21 of the gun-type controller 10. Then, as shown in FIG. 5A, the remaining time is further reduced to “85”, but the portion of the target character 228 can be further enlarged by setting the zoom rate to “× 80”.
[0094]
Furthermore, when the player continues to press the upward key of the operation data input unit 21 of the gun-type controller 10, the remaining time becomes “80” as shown in FIG. The portion of the target character 228 can be enlarged.
[0095]
Therefore, the player aligns the aiming position with the enemy character 228, pulls the trigger 14, and if the enemy character 228 exists on the trajectory line specified by the aiming position, it is determined that the enemy character 228 is hit, and the object of the enemy character Can give a given damage.
[0096]
In the present embodiment, when the enemy character 228 is damaged, an image indicating that the bullet hits the enemy character is displayed as shown in FIG.
[0097]
By the way, in the present embodiment, as described above, aim switching assigned to each direction key can be performed by pressing the right direction key or the left direction key of the operation data input unit 21 at any time. ing.
[0098]
6A to 6C show an example of a game image for explaining aim switching in the present embodiment.
[0099]
For example, when the player enlarges the image as shown in FIG. 6A, the player switches to aiming by the infrared camera as shown in FIG. 6B by pressing the right direction key 240 of the operation data input unit 21. Be able to.
[0100]
More specifically, the enemy character (target object) 244 hidden in the window 242 is displayed by switching to the display object for the infrared camera corresponding to the image of FIG.
[0101]
Further, the player can switch to the aiming by thermography as shown in FIG. 6C by pressing the left direction key 246, 248 of the operation data input unit 21.
[0102]
More specifically, the enemy character (target object) 252 lurking in the window 250 is displayed by switching to a thermographic display object corresponding to the image of FIG. 6A or 6C. ing.
[0103]
FIG. 7 shows an example of a flowchart of the zoom control process in the present embodiment described above.
[0104]
First, every time the player operates the gun-type controller 10 and designates an arbitrary position in the game screen of the display unit 190, the video signal from the processing unit 100 is first generated by the position calculation unit 22 of the gun-type controller 10. The designated position is detected using the synchronization signal included in the, and the designated position is selected as the gazing point (step S10).
[0105]
Subsequently, the operation data processing unit 106 determines the content of the operation data from the player via the operation data input unit 21 of the gun-type controller 10 (step S11).
[0106]
When it is determined by the operation data processing unit 106 that a direction key other than the up direction key among the cross direction keys of the operation data input unit 21 has been pressed (step S11: N), the process returns to step S10 and again the gun-type controller. 10 is selected.
[0107]
In step S11, when the operation data processing unit 106 determines operation data corresponding to the up direction key among the cross direction keys of the operation data input unit 21, it is determined that the up direction key has been pressed (step S11: Y). ), The processing unit 100 starts measuring time (step S12), and decrements (counts down) from the initial value “90” at regular time intervals.
[0108]
Subsequently, the operation data processing unit 106 determines the content of the operation data from the operation data input unit 21 of the gun-type controller 10 (step S13).
[0109]
In step S13, when the operation data processing unit 106 determines that the up key of the operation data input unit 21 has been input (step S13: Y), the angle of view is centered on the gazing point selected in step S10. Zoom control is performed so that the image near the gazing point is zoomed in to be narrowed (step S14).
[0110]
When it is determined in step S13 that the operation data operation unit 106 has input the down key instead of the up key of the operation data input unit 21 (step S13: N, step S15: Y), it is selected in step S10. The zoom control is performed so as to zoom out the image near the gazing point by widening the angle of view around the gazing point (step S16).
[0111]
When it is determined in step S15 that the operation data operation unit 106 has input the right direction key instead of the down direction key of the operation data input unit 21 (step S15: N, step S17: Y), FIG. 6B. As shown in FIG. 5, the display object is switched to the display object for the infrared camera screen instead of the display object so far (step S18).
[0112]
When it is determined in step S17 that the operation data operation unit 106 has input the left direction key instead of the right direction key of the operation data input unit 21 (step S17: N, step S19: Y), FIG. As shown in FIG. 4, the display object is switched to the display object for the thermography screen in place of the display object so far (step S20).
[0113]
The display object switched in step S18 or step S20 is obtained by a given conversion process for the normal display object shown in FIG.
[0114]
When it is determined in step S19 that the operation data operation unit 106 is not the left direction key of the operation data input unit 21 (step S19: N), or given in step S14, step S16, step S18, or step S20 After performing the screen control, the processing unit 100 checks the input of the trigger 14 of the gun-type controller 10 (step S21).
[0115]
If it is detected in step S21 that the trigger 14 has been pulled by the player by the processing unit 100 (step S21: Y), then a hit check is performed (step S22).
[0116]
That is, it is determined whether there is an enemy character object on the trajectory line specified by the indicated position of the gun-type controller 10 detected in step S10. When it is determined that there is an enemy character object at the time when the trigger 14 is pulled, it is determined that the object is a hit (hit) (step S22: Y), and the processing unit 100 is based on the time measured in step S12. Then, the score is calculated (step S23).
[0117]
In this scoring operation, for example, the more the remaining time is, the higher the score is, and the lower the score is, the lower the score is, so that the enemy character search technology and the aiming technology can compete. it can.
[0118]
When it is not detected in step S21 that the trigger 14 has been pulled by the player (step S21: N), or when it is determined in step S22 that no hit (hit) has occurred (step S22: N), step S13 Then, the input check of the cross direction key of the operation data input unit 21 is performed again.
[0119]
As described above, the zoom control process in the present embodiment is completed.
[0120]
As described above, the operation data input unit 21 including the cross direction key is provided in the gun-type controller 10 that can indicate an arbitrary position in the screen at a position away from the screen of the display unit 190, and zoom control that requires adjustment is required. The zoom control of the image near the designated position can be arbitrarily controlled in accordance with the operation data by each direction key (for example, the up direction key and the down direction key) of the cross direction key. As a result, the player can enlarge or reduce the target position with a quick operation, and can greatly change the game development according to the player's designated position, thereby providing a game with more complicated story development. Will be able to. Furthermore, since other command inputs are assigned to the other direction keys of the cross direction key, the player can experience more complicated game contents with an easy operation.
[0121]
(3) Other
In the shooting game realized by the present embodiment, it has been described that the difficulty level of changing the degree of progress of the game is not considered, but the present invention is not limited to this. For example, the zoom control speed operated by the player can be changed in consideration of the difficulty level.
[0122]
More specifically, when the difficulty level is set as “difficult” at the start of the game or during the game, it is not possible to easily enlarge or reduce the image to a desired size by increasing the zoom speed. Like that.
[0123]
Alternatively, for example, in consideration of the difficulty level, it is possible to change the size of an image that the player can zoom. More specifically, when the difficulty level is set as “difficult” at the start of the game or in the middle of the game, the size of the zoom rate at which the player can zoom in is limited, and the enemy character is enlarged to aim easily. Also make sure that you cannot hit.
[0124]
FIG. 8 shows an example of a flowchart of zoom control processing in which the zoom rate is limited in consideration of the above-described difficulty level.
[0125]
However, the same steps as those in the zoom control process in the present embodiment shown in FIG.
[0126]
Here, a given first restricted angle of view that restricts the angle of view that can be zoomed in, and a given second restricted angle of view that restricts the angle of view that can be zoomed out are defined.
[0127]
That is, when the difficulty level is set to “difficult”, when the operation data processing unit 106 determines in step S13 that the up key of the operation data input unit 21 has been input (step S13: Y), zooming is performed. The processing unit determines whether or not the angle of view is narrowed by a given amount to be equal to or less than a given first limited angle of view (step S30).
[0128]
When it is determined that the angle is less than the first limit angle of view (step S30: Y), the trigger input check in step S21 is performed without performing zoom-in control (step S21).
[0129]
On the other hand, when it is determined in step S30 that the angle of view is not less than the given first limit angle of view (step S30: N), the angle of view is narrowed around the gazing point detected in step S10. Zoom control is performed so as to zoom in on an image near the gazing point (step S14), and then a trigger input check in step S21 is performed (step S21).
[0130]
By doing so, the player can enlarge the image only up to the zoom rate specified by the first limited angle of view, so that it is assumed that it is more difficult to hit the target object.
[0131]
In step S13, when it is determined by the operation data operation unit 106 that the down key is input instead of the up key of the operation data input unit 21 (step S13: N, step S15: Y), the zoom processing unit It is determined whether or not the angle of view is widened by a given amount, it is greater than or equal to a given second limited angle of view (step S31).
[0132]
When it is determined that the given angle of view is greater than or equal to the second limit angle of view (step S31: Y), the trigger input check in step S21 is performed without performing zoom-out control (step S21).
[0133]
On the other hand, when it is determined in step S31 that the angle is not equal to or greater than the given second limited angle of view (step S31: N), the angle of view is widened around the gazing point detected in step S10. Zoom control is performed so that an image near the gazing point is zoomed out (step S16), and then a trigger input check in step S21 is performed (step S21).
[0134]
By doing so, the player can reduce the image only to the zoom rate specified by the second limited angle of view, and thus it becomes more difficult to search for the target object lurking in the wide virtual space. Is assumed.
[0135]
In addition, in the game system according to the present embodiment, it has been described that the game score changes depending on the measured time as shown in FIGS. 7 and 8, but the present invention is not limited to this. For example, the game result may be reflected according to the size of the image zoomed by the player using the gun-type controller 10.
[0136]
More specifically, when the player hits the target object with the gun-type controller 10, the smaller the zoom ratio at that time, the more difficult it is to hit, so the score can be further increased.
[0137]
With respect to the magnitude of the zoom rate, as shown in FIGS. 7 and 8, the game score that reflects the difficulty level can be generated more accurately by changing the game score in combination with the time measurement.
[0138]
Furthermore, in the game system according to the present embodiment, a frame in a given range centered on the position indicated by the gun-type controller 10 may be displayed on the game screen as an aim for aiming. In this case, by enlarging or reducing the game image in the frame displayed around the position specified by the player with the gun-type controller 10, the player can easily aim at the enemy character, and the game is interesting. Increase. Further, the position indicated by the gun-type controller 10 is displayed on the game screen as an aiming position, and shooting is performed by determining whether an enemy character exists on the ballistic line specified by the position. Thus, it is possible to improve the game performance such as competing for the aiming technique.
[0139]
FIGS. 9A to 9C show an example of a game image when zoom control is performed in the present embodiment in the case where an aim centered on the indicated position of the gun-type controller 10 is displayed.
[0140]
However, the same parts as those in FIGS. 5A to 5C are denoted by the same reference numerals, and description thereof will be omitted as appropriate.
[0141]
That is, when the player designates an arbitrary position in the game screen 220, the designated position 300 is displayed, and a frame 310 of a given range is displayed around the designated position 300.
[0142]
Therefore, the player indicates the position of the part where the target enemy character is supposed to lurk (instructed position 300), and the upward direction of the operation data input unit 21 of the gun-type controller 10 as shown in FIG. 9A. Press the key.
[0143]
Then, as shown in FIG. 9B, the game image within the frame of the given range is enlarged with the designated position 300 as the center. When the player wants to hit the enemy character 228 more reliably, the player further presses the upward key of the operation data input unit 21 of the gun-type controller 10. As a result, as shown in FIG. 9C, the portion of the target character 228 can be further enlarged with the zoom rate set to “× 120”.
[0144]
Therefore, when the enemy character 228 exists on the ballistic line specified by the designated position 300 by pulling the trigger 14, the player is determined to be hit, and performs a given damage to the enemy character object. Can be given.
[0145]
Therefore, as described above, it is possible to improve the game performance such as competing for the aiming technique by making it easier for the player to aim at the enemy character and shooting. Furthermore, after the player enlarges the game image in the frame 310 centered on the designated position 300 to a certain magnification, the player moves the designated position of the gun-type controller 10 to a position other than the enlarged game image, and then performs shooting. It will be possible to compete for advanced search and aiming techniques.
[0146]
In this case, the aiming position has been described as being displayed as a circle in a given range with the designated position 300 as the center, but it may be a square frame and is not limited to the shape of the frame. Further, the shape of the frame and the range of the frame may be appropriately changed with a cross direction key or the like. As a result, a finer search and aiming can be performed, and a more complicated shooting game can be provided.
[0147]
3. Other game system configurations
By the way, the game system (image generation system) of the present embodiment is not limited to the system having the configuration shown in FIG. That is, as shown in FIG. 1, the present invention is not limited to the gun-type controller 10 that detects the scanning light of the display unit 190 and detects the indicated position.
[0148]
FIG. 10 shows a functional block diagram of a game system (image generation system) according to another embodiment.
[0149]
The video camera 850 is an infrared imaging unit that captures a game image displayed on the display unit 820. The function of the video camera 850 is displayed on the game image by imaging the game image via an infrared transmission filter. Only the infrared spot light is captured.
[0150]
The gun-type controller 810 includes an indicator 812 (casing) formed in the shape of a gun, a trigger 814 provided on a grip portion of the indicator 812, and the vicinity of the muzzle 816 (light incident port) of the indicator 812. An infrared light emitting unit 818, a controller processing unit 820 for controlling the entire gun-type controller, an operation data input unit 822 including cross-direction keys for inputting different operation data according to the operation direction, A communication unit 824 that functions as an interface with the processing unit 800 is included.
[0151]
Here, the gun-type controller 810 can be gripped, and a trigger 814 and an operation data input unit 822 which is a cross-direction key are arranged at a position where the player can operate with one hand. It is desirable. For example, the player can further improve the operability by triggering the trigger 814 with the index finger and operating the cross direction key with the thumb of the same hand.
[0152]
The processing unit 800 includes a position detection area specifying unit 802, a position detection unit 804, a game information generation unit 806, a position determination unit 807, an operation data processing unit 808, and a zoom processing unit 809.
[0153]
The position detection area specifying unit 802 associates the coordinate position of the imaging area of the video camera 850 with the coordinate position of the game image area of the display unit 820 in advance by, for example, developing an image captured by the video camera 850 in the work memory area. The location of the spot light from the light emitting unit 818 of the gun-type controller 810 is specified in which of the areas obtained by dividing the game image area for each given area.
[0154]
The position detection unit 804 detects the position of the spot light of the gun-type controller 810 described above in the area specified by the position detection area specifying unit 802.
As described above, the position detection area specifying unit 802 specifies a previously divided area, and then performs a two-step process of determining in which position the spot light exists in the area, thereby detecting a complicated position. This makes it possible to reduce the processing and to detect the position with high accuracy.
[0155]
Similar to the game information generation unit 102 shown in FIG. 1, the game information generation unit 806 generates a game image (image viewed from a given viewpoint in the object space in a three-dimensional game) or game sound ( Game information such as BGM, sound effect, or voice) is generated and output to the display unit 820 and the sound output unit 830.
[0156]
Similar to the position determination unit 104 shown in FIG. 1, the position determination unit 807 allows the object displayed on the display unit according to the game process to pass through the indicated position (or ballistic line (in a broad sense, the indicated position) of the gun-type controller 810. A hit determination is performed by determining whether or not it exists in the line)).
[0157]
When the object is expressed in two dimensions, the object can be specified by whether or not the object exists at the indicated position on the display unit.
[0158]
Further, when the object is expressed in three dimensions, for example, a trajectory line specified by the indicated position on the display unit (in a broad sense, a line passing through the indicated position) is obtained, and whether or not the object exists on the trajectory line. The object can be specified by More specifically, it can be specified by an intersection check between a ballistic line and a simple object containing the object.
[0159]
Similar to the operation data processing unit 106 shown in FIG. 1, the operation data processing unit 808 discriminates the content of operation data from the gun-type controller that is appropriately input by the player during the game process. The determined contents are reflected on the object specified by the designated position.
[0160]
Similar to the zoom processing unit 108 shown in FIG. 1, the zoom processing unit 809 displays on the display unit 820 according to the indication position of the gun-type controller 810 and the operation data from the player determined by the operation data processing unit 808. The displayed image is enlarged or reduced.
[0161]
More specifically, when the player designates an arbitrary position of the display unit 820 using the gun-type controller 810, the zoom processing unit 809 uses the operation data input from the operation data input unit 822 when the object is expressed in three dimensions. Accordingly, zoom control is performed to widen or narrow the angle of view for the game image specified by the designated position.
[0162]
When the object is expressed in two dimensions, the game image specified by the designated position is zoomed so as to change the scaling of the two-dimensional display data in accordance with the operation data from the operation data input unit 822. Take control.
[0163]
In addition, the zoom processing unit 809 may linearly widen or narrow the angle of view of the image to be controlled for the zoom control. The angle of view of the resulting image may be widened or narrowed.
[0164]
Here, the image enlarged or reduced by the zoom processing unit 809 is displayed on the display unit 820, but is provided separately from another screen (such as a child screen) displayed on the display unit 820 or the display unit 820. You may make it display on other display parts or display parts, such as LCD provided in the gun type controller 810 which a player operates.
[0165]
Next, an outline of the operation of the game system of FIG. 10 will be described.
[0166]
First, the processing unit 800 generates a video signal, and the picture tube of the display unit 820 performs a light emitting operation based on the generated video signal. Thereby, an object such as a target object (enemy character) is displayed on the screen of the display unit 820. The projected screen is imaged by the video camera 850, and the processing unit 800 associates the coordinate position of the screen of the display unit 820 with the coordinate position of the imaging screen imaged by the imaging unit 852 of the video camera 850.
[0167]
Next, when the player aims the target object on the screen and directs the muzzle 816 of the gun-type controller 810 toward the display unit 820 and pulls the trigger 814, the spot light projected by the light emitting unit 818 at that time is displayed. The landing position is detected.
[0168]
In the detection of the landing position, the position detection area specifying unit 802 specifies an area where spot light exists from an area where the game screen of the display unit 820 is divided in advance with reference to the captured image of the video camera 850. Next, the position detection unit 804 detects in which position of the specified area the spot light exists.
[0169]
In the processing unit 800, based on the information on the detected designated position, the position determination unit 808 performs a hit check with the target object displayed on the screen. That is, when the target object is present at the indicated position, it is determined that a virtual shot from the gun-type controller 810 has hit the target object, and when the target object does not match, it is determined that the target object has come off.
[0170]
In this game system, operation data input from the operation data input unit 822 of the gun-type controller 810 is transferred to the processing unit 800 via the communication unit 824. The operation data processing unit 808 of the processing unit 800 determines a command corresponding to the transferred operation data, and reflects this in the game process.
[0171]
The present invention is not limited to the principle of detection of an arbitrary designated position in the screen of the display unit by the light transmission type controller, and it is possible to quickly perform a complicated operation such as an instruction in the screen and a command selection corresponding thereto.
[0172]

The data decompression processor 906 performs a decoding process for decompressing the compressed image data and sound data, and a process for accelerating the decoding process of the main processor 900. As a result, a moving image compressed by the MPEG method or the like can be displayed on the opening screen, the intermission screen, the ending screen, or the game screen. Note that the image data and sound data to be decoded are stored in the ROM 950 and the CD 982 or transferred from the outside via the communication interface 990.
[0177]
The drawing processor 910 performs drawing (rendering) processing of an object composed of primitive surfaces such as polygons and curved surfaces at high speed. When drawing an object, the main processor 900 uses the function of the DMA controller 970 to pass the object data to the drawing processor 910 and transfer the texture to the texture storage unit 924 if necessary. Then, the rendering processor 910 renders the object in the frame buffer 922 at high speed while performing hidden surface removal using a Z buffer or the like based on the object data and texture. The drawing processor 910 can also perform α blending (translucent processing), depth cueing, mip mapping, fog processing, bilinear filtering, trilinear filtering, anti-aliasing, shading processing, and the like.

[0181]
The RAM 960 is used as a work area for various processors.
[0182]
The DMA controller 970 controls DMA transfer between the processor and memory (RAM, VRAM, ROM, etc.).
[0183]
The CD drive 980 drives a CD 982 (information storage medium) in which programs, image data, sound data, and the like are stored, and enables access to these programs and data.
[0184]
The communication interface 990 is an interface for transferring data to and from the outside via a network. In this case, as a network connected to the communication interface 990, a communication line (analog telephone line, ISDN), a high-speed serial bus, or the like can be considered. By using a communication line, data transfer via the Internet becomes possible. Further, by using the high-speed serial bus, data transfer with other game systems becomes possible.
[0185]
All of the means of the present invention may be executed by hardware alone, or may be executed only by a program stored in an information storage medium or a program distributed via a communication interface. Alternatively, it may be executed by both hardware and a program.
[0186]
When each means of the present invention is executed by both hardware and a program, a program for executing each means of the present invention using hardware is stored in the information storage medium. Become. More specifically, the program instructs each processor 902, 904, 906, 910, 930, etc., which is hardware, and passes data if necessary. Each processor 902, 904, 906, 910, 930, etc. executes each means of the present invention based on the instruction and the passed data.
[0187]

[0189]
FIG. 12C shows a host device 1300 and terminals 1304-1 to 1304-n connected to the host device 1300 via a network 1302 (a small-scale network such as a LAN or a wide area network such as the Internet). An example of applying this embodiment to a system including In this case, the stored information is stored in an information storage medium 1306 such as a magnetic disk device, a magnetic tape device, or a memory that can be controlled by the host device 1300, for example. When the terminals 1304-1 to 1304-n are capable of generating game images and game sounds in a stand-alone manner, a game program and the like for generating game images and game sounds are received from the host device 1300. 1 to 1304-n. On the other hand, if it cannot be generated stand-alone, the host device 1300 generates game images and game sounds, which are transmitted to the terminals 1304-1 to 1304-n and output at the terminals.
[0190]
In the case of the configuration shown in FIG. 12C, each unit of the present invention may be executed in a distributed manner between the host device (server) and the terminal.
