DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic game device, a photographic game processing method, and an information storage medium for performing a game of simulating a target object displayed on a display device.

[0002]

2. Description of the Related Art In recent game machines installed in a game center or the like, a dedicated input device having a different structure is often used according to the type of each game device. For example, in a car racing game, an input device provided with a steering wheel, an accelerator, a brake, and the like and simulating a real vehicle is used. In a shooting game, an input device having a barrel portion, a trigger, and the like and simulating an actual gun is used. As described above, by using the dedicated input device in consideration of the game content, it is possible to realize a realistic game device.

In a conventional game device using the above-described various input devices, the more the input device has a special shape and usage, the stronger the impression of the features of the input device itself to the player. Therefore, when a new model game device is considered, a slight change in the game content without changing the input device will lack freshness as an impression received by the player. That is, when the same input device is used, it is difficult to give a fresh impression to the player even if the game content is slightly changed.

[0004] From such a background, a new game device using a camera as a new input device has been considered.
For example, Japanese Patent Application Laid-Open No. 2000-70548 discloses a “photographing game device” using a camera controller. The camera controller has substantially the same structure as a digital camera, and a predetermined shooting game proceeds by shooting a game screen on a projector using the camera controller. This shooting game machine includes a shooting evaluation unit that performs a negative evaluation of a shift in focus, a shift in angle, a blur, and the like with respect to a shooting result as a point to be deducted.

[0005]

In the shooting game apparatus disclosed in the above-mentioned publication, a part of a game screen displayed by a projector is actually used by using a camera controller having substantially the same structure as a digital camera. Since the photographing is performed and the scoring process is performed by evaluating the photographing result, there is a problem that the processing is complicated. In particular, regarding the evaluation of the shooting result, negative evaluations such as focus shift, angle shift, blurring etc. are deducted as points to be deducted, shooting the scene where the question is taken, for example, if it is a female model, besides elements such as composition It is described that if the best smile moment can be captured, a positive evaluation will be made, but if such evaluation is performed using actually shot images, advanced pattern matching is required. It is necessary to use the method described above, and the processing becomes complicated. In addition, considering that the above-described evaluation processing is performed every time the content of the game screen is updated (for example, every 1/60 second), it is necessary to use a CPU capable of performing extremely high-speed calculations, resulting in an increase in cost. It will also be.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a shooting game apparatus, a shooting game processing method, and information capable of reducing the processing load when calculating a score. It is to provide a storage medium.

[0007]

In order to solve the above-mentioned problems, a shooting game apparatus according to the present invention includes an input device, a display device, a game calculation unit, and a shooting position detection mechanism. The player can check the subject included in the shooting range through the finder window of the input device. The display device displays a predetermined game screen including a target to be photographed. The game calculation unit
A predetermined game calculation is performed based on the result of virtually photographing a part of the game screen using the input device. The shooting position detection mechanism detects an arbitrary position on the game screen at which the input device is pointed as a shooting position. Further, the above-described game calculation unit is configured to include an image generation unit, a shooting determination unit, and a score calculation unit. The image generating means generates image data of a game screen to be displayed on the display device.
The shooting determination means determines whether or not a predetermined task given to the player has been achieved by comparing the display position of the target included in the game screen with the shooting position detected by the shooting position detection mechanism. . The score calculation means calculates the score according to the result of the judgment by the photographing judgment means. In this way, when performing a game calculation based on the result of shooting using the input device, the success or failure of the task is determined by simply comparing the display position of the target and the shooting position, and the determination result Since the score calculation is performed in accordance with the score calculation, the processing load when the score calculation is performed can be reduced.

The above-mentioned photographing determination means sets a predetermined correct answer frame having a relative positional relationship with the display position of the target, and determines whether or not the correct answer frame includes the photographing position. It is desirable to perform a predetermined point addition process when the score calculation unit obtains a positive determination result by the imaging determination unit. Since a predetermined point addition process is performed according to the result of a simple comparison process of checking whether or not the shooting position is included in the correct answer frame, the processing load related to the score calculation can be reduced.

In addition, as the above-mentioned target, a first target to be added by photographing and a second target to be deducted by photographing are included. When the shooting position is included in the correct answer frame corresponding to the target, a predetermined point addition process is performed, and when the shooting position is included in the deduction frame corresponding to the second target, the predetermined deduction process is performed. desirable. Depending on the photographed target, not only the point addition but also the point deduction is performed. Therefore, the player needs to carefully select the target, so that the game content can be changed and the difficulty of the game can be increased.

It is desirable that the above-mentioned score calculating means calculates a score according to the distance between the display position of the target and the photographing position. Since the score changes according to the way the target is photographed, it becomes easy to change the difficulty of the game. For example, the player shoots a large number of targets in a short time regardless of the position in the shooting range, or places a target at almost the center of the shooting range and shoots a small number of targets over time. In some cases, it is necessary to instantaneously determine which one can get the high score, which motivates the player to try the game as many times as possible to get the high score.

Further, in the shooting game processing method according to the present invention, a first step of detecting a position on a game screen at which the camera-type input device is pointed, the detected position and a display position of a target on the game screen. And a third step of calculating a score according to the comparison result.

Further, the information storage medium of the present invention detects a position on a game screen at which the camera-type input device is pointed, compares the detected position with a display position of a predetermined target on the game screen, A program for performing a score process according to the comparison result is included. By performing the shooting game processing method of the present invention, or by executing a program stored in the information storage medium of the present invention, when an act of shooting a game screen using a camera-type input device is performed, Since the score calculation can be performed by comparing the shooting position with the display position of the target, the processing load in performing the score calculation can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a shooting game apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a shooting game apparatus according to the present embodiment. FIG. 2 is an external perspective view of the shooting game apparatus of the present embodiment. In the present embodiment, a description will be given of a business-use shooting game apparatus installed in a game center or the like, for example.

As shown in FIGS. 1 and 2, a shooting game apparatus according to this embodiment includes two camera-type input devices 10 and 2.
0, a display device 30, a coin insertion unit 40, a start button 42, a game calculation unit 50, a video output unit 60, an audio output unit 70, a speaker 72, and an information storage medium 80.

The camera-type input device 10 is a dedicated controller that simulates the structure of a camera, and has the same operability as a general-purpose digital camera or a camera loaded with a photographic film. FIG. 3 is an external perspective view of the camera-type input device 10. The camera-type input device 10 illustrated in FIG. 3 includes a light receiving unit 12, a shutter switch 14, and a coordinate detection unit 16. As shown in FIG. 3, the camera-type input device 10 is provided with a finder window 18. When the player looks through the finder window 18, the player can confirm a subject included in the shooting range through the lens system 19. It has a single-lens reflex structure that can be used.
By pressing the shutter switch 14, the player can send an instruction to the game calculation unit 50 to virtually shoot an image in the shooting range visually confirmed through the finder window 18.

FIG. 4 is a diagram showing a screen configuration inside the finder window 18. As shown in FIG.
8, a center marker 1 indicating the center position of the photographing range
8a, a photographing range frame 18b indicating a photographing range, and an out-of-range region 18c included in the visual field range and corresponding to a region outside the photographing range frame 18b. Shooting range frame 18
b is a photographable range, and an out-of-range area 18c outside the photographing range frame 18b is used to assist the operation of the player. That is, by having the out-of-range area 18c, when the moving subject is going to enter the shooting range frame 18b, the movement of the subject is detected before the subject enters the shooting range frame 18b. The player can use the finder window 1
8, the position of the center marker 18a can be quickly moved to the position of the subject.

The shutter switch 14 depends on the player.
Is pressed, the coordinate detecting unit 16 sets the display device 30 to which the lens system 19 of the camera-type input device 10 is pointed.
Detect any position on the screen. Camera type input device 10
Thereafter, when the shutter switch 14 is pressed, a photographing signal is output, and when an arbitrary position on the screen is detected by the coordinate detecting unit 16, a coordinate detection signal including the coordinate data of the arbitrary position is output. Note that the camera-type input device 20 also has the same structure, and includes a light receiving unit 22, a shutter switch 24, and the like.

The display device 30 displays a game image on a screen based on an input video signal. The display device 30 has a raster scanning type structure,
For example, it is constituted by a CRT (cathode ray tube). Since the raster scanning type display device 30 performs display by predetermined scanning, when the entire screen is simultaneously lit (display operation of illuminating the entire screen is “flash display”, the screen generated by flash display is “flash display”). In this case, the time at which a pixel at an arbitrary position facing the camera-type input device 10 shines differs depending on the horizontal and vertical coordinates of the arbitrary position.
Therefore, the user directs the camera-type input device 10 to an arbitrary position on the display device 30 and then sets the shutter switch 14
By measuring the time from the start of the flash display of the screen by operating to the time at which the pixel at the above-mentioned arbitrary position shines, it is possible to know the coordinates of the arbitrary position within the display screen with the camera-type input device 10 turned. it can.

Note that when a game screen is displayed on the screen of the display device 30, the center position of photographing is detected using the camera-type input device 10, so that the screen at the time of flash display is displayed. The light amount is set so as to be equal to or greater than the light amount of the normal game image, so that the detection operation of an arbitrary position on the screen is not erroneously performed in response to the normal game image.

The coin insertion section 40 is a section where the player inserts coins. The start button 42 is for the player to instruct the start of the game. The game calculation unit 50 controls the entire photographing game device. When a player inserts a coin into the coin insertion unit 40 and further presses a start button 42, the game execution unit 50 executes a predetermined game program, thereby executing a predetermined game program. The arithmetic processing of the shooting game using the pattern input devices 10 and 20 is started. Further, the game calculation section 50 determines whether or not the game is over. For example, the game calculation unit 50
Measures the elapsed time from the start of the game calculation, and determines that the game is over when a predetermined time has elapsed from the start of the game. When the game is over, the game calculation section 50 ends the calculation processing of a series of shooting games.

The video output unit 60 includes a current screen memory 62 corresponding to a display screen, and a previous screen memory 64 storing the contents of the immediately preceding display screen. The video output unit 60 reads out the image data generated by the game calculation unit 50 and stored in the current screen memory 62 in the scanning order, and converts the read image data into a predetermined video signal (such as an RGB signal or an NTSC signal). A predetermined game image is displayed on the screen. The current screen memory 62
Is completed, the image data stored in the current screen memory 62 is stored in the previous screen memory 64.

The audio output section 70 converts various audio data output from the game operation section 50 into analog audio signals and outputs the analog audio signals from the speaker 72. Information storage medium 80
Is a program executed in the game calculation unit 50,
The image data and the audio data for the question corresponding to each mini game are mainly stored. For example, a semiconductor memory or a hard disk device is used. Or D
A VD or a CD may be used as an information storage medium, and a program or the like read by these reading devices may be input to the game calculation unit 50.

The game calculation unit 50 shown in FIG.
Game progress processing section 51, image generation section 52, timing determination section 53, shooting center position specifying section 54, shot image extraction section 5
5, a photographed image storage unit 56, a photographing determination unit 57, and a score calculation unit 58.

The game progress processing unit 51 performs a game calculation necessary for progressing the shooting game of the present embodiment.
For example, in the present embodiment, a plurality of mini-games having different contents are prepared, and when any of the mini-games is selected by the player, an instruction to generate a question image corresponding to the selected mini-game is issued by the game progress processing unit. The image data is sent from 51 to the image generation unit 52.

The image generating section 52 generates question image data prepared for each mini game, and displays image data for displaying scores of each player and the result of each player shooting a part of the display screen. Generate captured image data to be partially displayed. These image data are stored in the current screen memory 62 at the timing when the screen is not displayed.

The timing judging section 53 flashes a screen in order to perform a predetermined photographing process in accordance with a photographing instruction of the player in accordance with a photographing signal input from each of the camera-type input devices 10 and 20. Is determined. As described above, the camera-type input devices 10, 20
Is configured to detect each shooting position by flashing the entire screen of the display device 30, but in the present embodiment, the image is displayed at a timing immediately before the screen flashed. The captured image is captured using the screen. For this reason, when a photographing signal is output from the camera-type input devices 10 and 20 and the display screen being scanned at that time is not the screen that is flashed, the next screen is flashed according to the photographing signal. If the display screen being scanned at that time is a screen flash-displayed, the operation of flashing the next screen is delayed by one screen. In this way, by preventing two consecutive screens from becoming a flash screen, that is, by forcibly inserting a game screen between the two flash screens, when a shooting signal is input at any timing, Even if there is, the cutout processing of the photographed image becomes possible.

The photographing center position specifying section 54 specifies the photographing center position based on the coordinate data included in the coordinate detection signals output from the camera type input devices 10 and 20. Basically, the coordinates of the center position of photographing are detected by the coordinate detection unit 16 in the camera-type input device 10 (or 20), and the coordinate data included in the coordinate detection signal is generated. By using this, the center position of shooting can be specified. However, in actuality, the shooting center coordinates are calibrated at the time of manufacture or installation of the shooting game device, and the calibration process is performed in each of the horizontal direction and the vertical direction. An offset value has been set. Therefore, the photographing center position specifying unit 54 adds the offset value to the coordinate data (horizontal position data and vertical position data) included in the coordinate detection signal input from each of the camera-type input devices 10 and 20. Specifies the center position of the photographed image after the calibration processing.

The photographed image extracting unit 55 sets a predetermined range around the photographing center position specified by the photographing center position specifying unit 54 as a photographing range, and cuts out an image on the display screen included in the photographing range. Perform processing. The photographing range where the image is cut out is set so as to substantially coincide with the photographing range 18b set in the finder window 18 of the camera-type input devices 10 and 20 described above.
Further, in the shooting game apparatus of the present embodiment, the image shot by operating the camera-type input devices 10 and 20 is displayed using a partial area of the screen on which the question image is displayed. Has become. For this reason, the photographed image extracting section 55 converts the cut photographed image data into an image
Output to.

The photographed image storage unit 56 includes the photographed image extracting unit 5
5 stores the image data corresponding to the photographed image cut out. For example, assuming that the last three captured images are displayed using a part of the screen corresponding to each of the camera-type input devices 10 and 20, the captured image storage unit 56 includes six images in total. And has a storage area corresponding to the captured image, so that the latest captured image is overwritten cyclically.

The photographing judging section 57 judges whether or not the task obtained by operating the camera type input devices 10 and 20 and achieving the task given for each selected mini game has been achieved. I do. For example, when a specific target is displayed at a specific position at an instantaneous timing, and given that each player is given the task of shooting this target only once as a subject, the shooting determination unit 57 Whether or not the timing at which the player has pressed the shutter switch 14 of the camera-type input devices 10 and 20 to give a shooting instruction coincides with the display timing of the target, and whether or not this target is included in the shooting range Is determined. If the task has been achieved and a positive determination result has been obtained, a correct answer determination is made. Conversely, if at least one of the determination results is negative, it is determined that the task has not been achieved.

The score calculation unit 58 performs a predetermined score calculation according to the judgment result by the photographing judgment unit 57. As a method of calculating the score, several patterns corresponding to the contents of the shooting game can be considered. Details of the shooting game and a specific example of the score calculation will be described later.

Each of the light receiving units and the coordinate detecting unit in the above-mentioned camera type input devices 10 and 20, a photographing center position specifying unit 54,
Timing determination unit 53, image generation unit 52, video output unit 6
0 corresponds to the photographing position detecting mechanism. The image generation unit 5
Reference numeral 2 corresponds to an image generation unit, the shooting determination unit 57 corresponds to a shooting determination unit, and the score calculation unit 58 corresponds to a score calculation unit.

The shooting game apparatus of the present embodiment has such a configuration, and its operation will be described below. 5 to 7 are diagrams showing specific examples of mini-games that can be selected in the shooting game device of the present embodiment. In the mini game shown in FIG. 5, one scene of a baseball game is a question image, and the correct answer is determined by capturing the moment when the batter hits the ball thrown by the pitcher. In this mini-game, there is only one shooting chance.

In the mini-game shown in FIG. 6, the appearance of the sky above the future city is used as the question image, and the correct answer is determined by photographing the spacecraft flying over the sky. In this mini-game, the number of times of shooting is not limited, and the higher the spacecraft is shot, the higher the score is given.

In the mini-game shown in FIG. 7, numbers arranged on the entire screen are used as question images, and "7" is searched for and photographed. For example, three photo opportunities are given, and a high score is given when all three “7” displayed at different positions are photographed.

As shown in FIGS. 5 to 7, a region for displaying a photographed image (hereinafter, this region is referred to as a "photographing result display region") is provided at the lower part of the game screen of this embodiment. ) Is provided, and three captured images can be displayed on each of the two players. In the mini-game shown in FIG. 5, since each player is given one photo opportunity, only one shot image is displayed in the shooting result display area for three frames prepared for each player. You. In the mini game shown in FIG. 6, since the number of times of the photo opportunity is not particularly limited, the latest three photographed images are displayed in the photographing result display area described above. FIG.
In the mini-game shown in (3), the number of shutter chances is three, which is equal to the number of frames included in the shooting result display area prepared for each player. Therefore, all three shot images are displayed in the shooting result display area.

FIG. 8 is a flowchart showing the operation procedure of the shooting game apparatus of the present embodiment. The game progress processing section 51 in the game calculation section 50 is operated by the player to insert the coin into the coin insertion section 4.
It is determined whether or not a coin has been inserted into the “0” (step 1).
00). When a coin is inserted, the game progress processing unit 51 determines whether or not the player has pressed the start button 42 (step 101). When the start button 42 is pressed, the game progress processing unit 51 displays a predetermined game selection screen including a plurality of selectable mini-games prepared in advance as options (step 102). For example, the game progress processing unit 5
1 sends an instruction to generate a game selection screen to the image generation unit 52, and the option image data including the name of each mini game together with the characteristic scene of each mini game is sent to the image generation unit 5.
2 generated. The option image data is alternately written to the two screen memories 62 and 64 in the video output unit 60, and a predetermined game selection screen is displayed on the display device 30.

Next, the game progress processing section 51 repeats the process of determining whether any mini-game included in the game selection screen has been selected until any mini-game is selected (step 103). ). For example, the player shoots one of the mini-game option images displayed on the screen using one of the camera-type input devices 10 and 20 to play a mini-game corresponding to the shot option image. You can choose. When one of the mini-games is selected by the player, an affirmative determination is made in the determination at step 103, and then the game progress processing unit 51 describes the content of the selected mini-game (step 104).

Next, the game progress processing section 51 performs a countdown process for displaying a question image of the selected mini game (step 105). Specifically, an instruction is sent to the image generation unit 52, and “5”, “4”, “3”,
A countdown screen is generated in which gradually smaller numbers such as “2” and “1” are included in the entire screen of the display device 30.

When the countdown processing is completed, the game progress processing section 51 displays a game screen corresponding to the selected mini game (step 106). The display of the game screen is performed by writing the image data of the game screen into the current screen memory 62 in the video output unit 60 by the image generation unit 52. When the display of one screen using the current screen memory 62 ends, the image data stored in the current screen memory 62 is stored in the previous screen memory 64.

Further, the timing determination section 53 determines whether or not it is the shooting timing for flashing the screen (step 107). When it is determined that the timing for flash display has been reached, the timing determination unit 53
Sends an instruction to flash the next screen to the image generation unit 52, and specifies the coordinates of the shooting center position by the shooting center position specifying unit 54 (step 108).

FIGS. 9 and 10 are diagrams for explaining the photographing timing. These figures show the camera type input device 1
5 shows the relationship between the photographing signals input from 0 and 20 and the contents of the current screen memory 62 and the previous screen memory 64 in the video output unit 60. Is shown. The current screen memory 62 or the previous screen memory 64 in which image data for flash display is written is hatched.

As shown in FIG. 9, the camera type input device 1
If a shooting signal is input from at least one of 0 and 20 and the display screen at that time is not a flash screen, that time is the shooting timing for generating a flash screen. In this case, the next time the screen goes into the non-display state, the image data for flash display is written to the current screen memory 62, and the flash display is performed on the next screen.

As shown in FIG. 10, when a photographing signal is input from at least one of the camera-type input devices 10 and 20, and the display screen at that time is a flash screen, after the next screen is displayed, When this screen is in a non-display state, image data for flash display is written to the current screen memory 62. Therefore, the screen displayed immediately after the shooting signal is input becomes the normal game screen, and the normal game screen is forcibly placed between the next flash screen and the previous flash screen. Inserted.

Next, the photographing judging section 57 makes a right / wrong judgment for checking whether or not the predetermined object set as the target has been photographed (step 109). The corresponding score is calculated (step 110). For example, in the case of the mini-game shown in FIG. 5, since the moment at which the batter hits the ball thrown by the pitcher is the target set as the shooting target, when both the shooting timing and the shooting position match. Then, the correctness determination is performed by the shooting determination unit 57, and the point calculation unit 58 performs the point addition processing for the player who is the target of the correctness determination.

In the case of the mini-game shown in FIG. 6, a continuously flying spaceship is a target set as an object to be photographed. When they match, the correctness determination is performed by the shooting determination unit 57, and the point calculation unit 58 performs point addition processing for the player who has been the target of the correctness determination.
In this mini-game, the spacecraft can be photographed any number of times within the time limit, and each time the correct answer determination and the point addition processing are repeated.

In the case of the mini-game shown in FIG. 7, since the image of the fixed number "7" is the target set as the object to be photographed, this number "7" is displayed. When the current position matches the shooting position, the shooting determination unit 57 performs a correct answer determination, and the score calculation unit 58 performs a point addition process for the player for which the correct determination is performed. Also, in this mini game, since three chances of photographing three numbers “7” displayed at different positions within the time limit are given three times, the correct answer determination and the point addition processing are repeated up to three times. .

A specific example of the processing method of the right / wrong judgment and the score calculation corresponding to each of the mini-games shown in FIGS. 5 to 7 will be described later. Next, the photographed image extracting unit 5
5 calculates a photographing range based on the photographing center position extracted by the photographing center position specifying unit 54 (step 11).
1) Cut out the display image within the shooting range (step 11)
2), the image is stored in the captured image storage unit 56 (step 1)
13). For example, assuming that a rectangular area of height a × width b is to be a photographing range by photographing a display screen with the camera-type input devices 10 and 20, the photographed image extracting unit 55
Is a range along the X-axis direction (horizontal direction) based on the coordinates (X0, Y0) of the specified photographing center position: X0−a / 2 ≦ X
≦ X0 + a / 2, range along the Y-axis direction (vertical direction); Y0−b / 2 ≦ Y
An area corresponding to the coordinates (X, Y) satisfying ≦ Y0 + b / 2 is calculated as a photographing range.

The image data corresponding to the photographing range is cut using the image data stored in the previous screen memory 64 in the video output unit 60. Since the detection of the center position of photographing is performed by flashing the entire screen, image data of the photographing range cannot be extracted from the flashed screen. For this reason, in the present embodiment, the image data is cut out from the normal game screen displayed immediately before the flash screen.

As described above, the photographed image storage unit 5
Numeral 6 has a capacity capable of storing image data extracted by three shots for each player, and when shooting more than three times is allowed (as in the mini game shown in FIG. 6). In the case where there is no limitation on the number of times of photographing, for example), only the image data corresponding to the latest three times of photographing is stored.

Next, the game progress processing unit 51 determines whether a predetermined end condition is satisfied (step 11).
4). For example, when a time limit is provided, it is determined whether or not the time limit has been exceeded since the game was started. When the time limit is set and the number of times of shooting is set, it is determined whether or not the time limit has been exceeded since the game was started, or whether or not the number of times of shooting has reached the predetermined number of times. Is determined. If the predetermined end condition is not satisfied, a negative determination is made in the determination of step 114, and the process returns to step 106 described above to continue the processing after displaying the question image by switching the display screen.

If the predetermined termination condition is satisfied, an affirmative determination is made in the determination at step 114, and then the game progress processing unit 51 performs a predetermined game over process (step 115). For example, the game progress processing unit 51
Sends an instruction to the image generation unit 52, and a predetermined ending screen including the score for each player is displayed. Thus, the game calculation for the series of mini-games selected by the player is completed.

Next, the right / wrong judgment (step 10) performed in correspondence with each of the mini-games shown in FIGS.
A specific example of the processing method of 9) and the score calculation (step 110) will be described. First, in various types of mini-games, a description will be given of criteria for determination in the shooting determination unit 57 and the score calculation unit 58 when a task of “shot a target” is given. Generally, "Shoot the target"
When the expression is used, (1) when imaging is performed so that the entire target is included in the imaging range, (2) when imaging is performed so that the imaging range includes at least a part of the target, (3) Imaging may be performed such that the target is arranged substantially at the center of the imaging range, or (4) imaging may be performed such that the target is arranged at a predetermined position in the imaging range.

(1) The entire target is included in the shooting range
If 11 to shoot as is a diagram showing a criterion for determination in the case of performing the correct decision when taken to include the entire target shooting range. In FIG. 11, the area 310 is the target object 30.
This corresponds to the case where the entirety of 0 is completely included in the lower left portion of the shooting range, and the center position of shooting having such a shooting range is A1.

The area 330 is the target 30
This corresponds to the case where the entirety of 0 is completely included in the upper right part of the shooting range, and the center position of shooting having such a shooting range is A3. The region 340 corresponds to the case where the entire target object 300 is completely included in the lower right part of the shooting range, and the center position of shooting having such a shooting range is A4. The fact that the region 350 surrounded by these four center positions A1 to A4 includes the center position of shooting indicates that the entire target object 300 is included in the shooting range.

Accordingly, as shown in FIG. 11, the photographing determination section 57 checks whether or not the region 350 centered on the display position B1 of the target 300 includes the center position of the photographing, thereby determining the photographing range. It is possible to know whether or not the entire target is included in the image, and to perform a simple comparison operation without actually examining the contents of the captured image and analyzing whether or not the image of the target is included. It is possible to make a right / wrong determination on the assigned task. Note that, depending on the size and shape of the target object 300, the positions of the center positions A1 to A4 of the four regions 310 to 340 change, so that the size of the region 350 used for correctness determination also needs to be changed.

It is possible to know whether or not a target is included in the approximate center of the image, and by simply examining the contents of the captured image and analyzing whether or not the image of the target is included, a simple comparison operation allows It is possible to make a right / wrong determination for a given task.

(4) The target is arranged at a predetermined position in the shooting range
If Figure 14 for taking as is a diagram showing the criteria for determining when to perform correct judgment when the target is shot to be placed in a predetermined position of the imaging range. In FIG. 14, an area 610 corresponds to the shooting range when the target object 300 is located at the upper right portion of the shooting range. The area 620 is “the upper right part”
Indicates the allowable range for the expression
The fact that the shooting center position is included in 20 indicates that the target object 300 is included substantially at the upper right of the shooting range.

Therefore, as shown in FIG. 14, the photographing determination section 57 checks whether or not the region 620 having a predetermined positional relationship with the display position B1 of the target 300 includes the center position of the photographing. As a result, it is possible to know whether or not the target is included almost at the upper right of the shooting range, and it is easy to check the contents of the captured image without actually analyzing whether or not the image of the target is included By a simple comparison operation, it is possible to determine whether the given task is correct or not.

When a position other than the upper right of the photographing range is designated as a given task, an area 62 corresponding to the display position B1 of the target object 300 is designated according to the designated contents.
The position and size of 0 may be changed as appropriate. in this way,
Whether or not the target object displayed on the screen has been photographed is determined by determining whether the center position of the photographing is in a predetermined area (hereinafter, this area is referred to as a “correct answer frame”).
This can be confirmed by a simple comparison operation of checking whether or not the target object is actually displayed on the screen together with this comparison operation. You also need to find out.

In the mini-game shown in FIG. 5, since a task of "take a picture of the moment when the batter hits the ball" is given, a very short time range is a photo opportunity. For example, as shown in FIG. 16, if it is assumed that the target (the moment when the bat hits the ball) is included only in the screen for three frames including the moment when the batter hits the ball, the photographing determination unit 57 determines in FIG. In step 201 shown in (1), it is determined whether or not the target is displayed by checking whether or not the determination timing matches the display timing of the screen for three frames.
Further, as shown in FIG. 16, a correct answer frame 710 is set such that the position where the bat hits the ball is substantially at the center of the shooting, and the shooting determination unit 57 determines this correct answer in step 202 shown in FIG. It is determined whether or not the frame 710 includes the center position of shooting.

FIG. 17 is a diagram showing a specific criterion for correctness / incorrectness corresponding to the mini game shown in FIG. In the mini-game shown in FIG. 6, since the task of “take a picture of the always displayed spaceship” is given, the photographing determination unit 57 may omit the determination in step 201 shown in FIG. it can. Also, as shown in FIG. 17, since the correct answer frame 720 also moves along the flight path of the spacecraft, the imaging determination unit 57 determines in step 202 shown in FIG.

If the center position of photographing is not included in the display screen (if the determination in step 300 is negative), the point addition process in step 303 is not performed, and the process proceeds to step 111 shown in FIG. Transition. In addition, when the first target is not displayed on the screen (when a negative determination is made in the determination of step 301), and when the center position of imaging is not included in the correct answer frame (a negative determination is made in the determination of step 302). Is performed), the imaging determination unit 57 next determines whether or not the second target set as the subject to be deducted is displayed on the screen (step 304). In
Further, it is determined whether or not the center position of the photographing is included in the deduction frame (step 305). If it is included, an affirmative determination is made, and then the score calculation unit 58 performs a predetermined deduction process (step 306).

As described above, in the shooting game apparatus of the present embodiment, when the game calculation is performed based on the result of shooting using the camera-type input devices 10 and 20, the display position of the target and the shooting position are simply determined. In the case where the success or failure of the task achievement is determined by comparing with the above, the score calculation is performed according to the determination result, and the content of the captured image is actually examined to analyze whether or not the image of the target is included. It is possible to reduce the processing load when performing the score calculation as compared with.

Particularly, in order to determine whether or not the task given to the player has been achieved, a correct answer frame having a predetermined positional relationship with the display position of the target is set.
Since a predetermined point addition process is performed according to the result of a simple comparison process of checking whether or not the shooting position is included in the correct answer frame, the processing load related to the score calculation can be reduced. In addition, when setting a deduction frame corresponding to a target to be deducted at the time of shooting, it is necessary to carefully select and shoot the target, and the game content can be changed.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. In the above-described embodiment, the center position of shooting on the display screen is detected by combining the raster scanning type display device 30 including a CRT or the like with the camera type input device 10 having the light receiving unit 12 or the like. However, the mechanism for detecting the center position of photographing is not limited to this. For example, if a camera-type input device is provided with a position sensor or an angle sensor to directly detect the center position of photographing, the display device 30 may be implemented using a liquid crystal display device or a liquid crystal projector that does not perform raster scanning. Can be. In addition, a camera-type input device is provided with an infrared light emitting unit or the like, an irradiation point on the screen is photographed by photographing means such as a CCD camera, and the photographed image is analyzed to specify a center position of photographing. Is also good.

FIG. 20 is a diagram showing a configuration of a shooting game apparatus using a camera-type input device having a light emitting section. FIG.
The photographing game device shown in FIG. 0 is different from the photographing game device shown in FIG. 1 in that a mechanism for detecting the center position of photographing is changed. The following description focuses on this difference.

The camera-type input device 10 A has a light emitting section 13 and a shutter switch 14. It is assumed that the camera-type input device 20A has the same configuration. The light emitting unit 13 emits light including a wavelength component of infrared rays, and is configured by, for example, a semiconductor laser. The laser light emitted from the light emitting unit 13 is emitted toward the display screen of the display device 30 as a substantially converged spot light beam by passing through the lens system of the camera-type input device 10A.

The camera 90 is for photographing the screen 92. The screen 92 is formed of a translucent member, and is arranged in front of the display device 30 and at a position where the line of sight of a player looking at the screen of the display device 30 is blocked. The player
The game image displayed on the screen of the display device 30 can be viewed through the screen 92. From the camera type input devices 10A and 20A to the display device 3
When the laser light is emitted toward an arbitrary position on the screen 0, an image is formed by the laser light at a position on the screen 92 corresponding to the arbitrary position on the screen. The camera 90 takes an image of the entire screen 92 including the image and generates image data.

The shooting center position specifying unit 54A in the game calculation unit 50A analyzes the image of the screen 92 shot by the camera 90, and
The photographing center position on the display screen by 0A and 20A is specified. As described above, when the light-emitting unit provided in the camera-type input device emits light to specify the center position of shooting, the screen of the display device 30 does not need to be flash-displayed, and the switching timing of the display screen (scanning timing) Regardless of the timing, the center position of the photographing can be specified.

In the above-described embodiment, the photographing game device for business use has been described. However, a similar mechanism may be realized by connecting a camera-type input device to a game device for home use. In the above-described embodiment, a camera-type input device having a single-lens reflex structure is used, but a camera-type input device having a finder structure may be used. In this case, it is not necessary to use the same or similar lens system as the actual camera.

In the above-described embodiment, the point addition processing is performed when the predetermined correct answer frame includes the center position of the photographing.
The point deduction processing is performed when the predetermined deduction frame includes the center position of the photographing. However, several modified examples of the points to be added and the degree of the points deduction are conceivable. For example, when setting a score corresponding to the difficulty of shooting caused by a difference in the size or moving speed of the target, when setting a score corresponding to the distance between the display position of the target and the center position of shooting,
There may be a case where a high score is set when only a plurality of types of target objects are displayed and only the same type of target object is selectively photographed. For example, when a score is set according to the distance between the display position of the target and the center position of the shooting, the player may shoot many targets in a short time regardless of the position within the shooting range. It is necessary to instantaneously determine which one can obtain a high score when taking a small number of targets by arranging the target at approximately the center of the shooting range over time, and obtaining a high score. Motivated to try the game over and over.

In the above-described embodiment, typical mini-games are shown in FIGS. 5 to 7 as specific examples of mini-games. The mini-games of the same kind belonging to these three categories are shown below. Something like that is possible. As the mini game of the same kind as the mini game shown in FIG. 5, the following contents can be considered. -A game screen is displayed in which the snowboarder jumps out of the jumping platform one after another and takes a pose, and from this, a designated pose is taken.・ Shoot the moment when a racing car crosses the screen in an instant. -On the game screen displaying the goal of the horse race, capture the moment the first-place racehorse finishes. -On the game screen displaying the golf swing, capture the moment when the ball is hit with the driver.

As the mini game of the same kind as the mini game shown in FIG. 6, the following contents can be considered.・ Shoot many license plates of a car running meandering. -When the train crosses the screen, take a picture of the window where the designated person is.

As the mini-game of the same kind as the mini-game shown in FIG. 7, the following mini-games can be considered.・ Numbers are lined up, and shoot numbers in ascending or descending order. -Look at the two pictures displayed, search for mistakes, and shoot the found mistake.

The mini-games described above are specific examples, and other shooting games utilizing the features of the camera-type input device may be played. For example, as shown in FIGS. 13 and 14, by adjusting the set position of the correct answer frame (areas 520 and 620), a mini game in which the position of the target within the shooting range is designated may be performed. . More specifically, an apple is displayed at the center of the screen, and for each of a plurality of photo opportunities, a position in the shooting range in which the apple is to be shot is specified. The difficulty of the game can be increased as compared to a case where the apple is simply photographed.

In the embodiment described above, the coordinate detection unit 16 is provided in the camera-type input device 10 and the shooting center position specifying unit 54 is provided in the game calculation unit 50. They may be put together. For example, the coordinate detection unit 1 in the camera-type input device 10
6. The function of the photographing center position specifying unit 5 in the game calculation unit 50
4, the output signal of the light receiving unit 12 may be directly input to the photographing center position specifying unit 54.

[0085]

As described above, according to the present invention, when performing a game calculation based on the result of shooting using a camera-type input device, the display position of the target and the shooting position are simply compared. Thereby, the success or failure of the task achievement is determined, and the score calculation is performed in accordance with the determination result, so that the processing load when performing the score calculation can be reduced.
