Description

  The present invention relates to a shooting game machine, and more particularly, to a shooting game machine using an infrared detection method, and to a game difficulty and a game environment according to a distance measured using a plurality of reference points arranged at irregular intervals. The present invention relates to a shooting game machine and a method for executing the same, which provide a game that is more realistic and interesting by giving changes.

  The present invention is an invention corresponding to an improvement to the adjustment of the difficulty level and the situation in the game of application number 10-2002-43913 filed on July 25, 2002 by the present applicant, and closely related to the present invention. As for the relevant parts, the contents already filed will be used together.

  Considering FIG. 1 showing a perspective view of a shooting game machine according to the prior art, the shooting game machine according to the prior art is a game device box 1 of a shooting game machine, a screen 1a, a video generator 2 arranged in the box, A translucent reflecting mirror 3 for displaying an image generated from the image generator 2 on the screen 1a, an infrared generator 4 for generating a reference point 7 as a basis for coordinate calculation, and a control for controlling the entire game machine. Coordinate detection means 6 for detecting designated coordinates 8 designated by the player based on the reference point 7 generated by the means 5 and the infrared ray generator 4 is included.

  The shooting game machine includes a model gun 10 for indicating a target on the image displayed on the screen 1a. The model gun 10 includes a barrel 10a, a trigger 11, a vibration isolating member 12 such as rubber, An image detected through the CCD camera 13, including a CCD camera 13, a lens 14, and an infrared transmission filter 15, is transmitted to the coordinate detection means 6 through a communication line 16 connected to the model gun 10. The CCD element of the CCD camera 13 is generally rectangular, and is usually arranged and used so that the side with a large number of pixels faces the horizontal axis.

  In the shooting game machine configured as described above, the display means for displaying the video of the game is composed of the screen 1a, the video generator 2 and the translucent reflecting mirror 3, but transmitted from the control means 5 The video information of the game including the target is converted into light in the visible light region by the video generator 2 and then reflected by the translucent reflecting mirror 3 and finally scanned by the screen 1a. Is observed by the player. At that time, the light emitted from the infrared ray generator 4 is reflected by the semi-transparent reflecting mirror 3 and scanned on the screen 1a, thereby displaying a reference point 7 as a basis for coordinate detection.

  The game player directly holds the model gun 10 and gives an instruction toward the display screen 1a. At this time, the image displayed on the screen 1a and the reference point 7 pass through the infrared transmission filter 15 of the model gun 10, but light in the visible light region cannot pass through the infrared transmission filter 15, The reference point 7 that is light in the infrared region passes through the infrared transmission filter 15.

  The reference point 7 that has passed through the infrared transmission filter 15 is imaged on the CCD camera 13 through the lens 14, and the reference point 7 imaged on the CCD camera 13 is converted into an electric signal image and is converted into the image of the electric signal. The data is transmitted to the coordinate detection means 6 via the communication line 16. At this time, when the player pulls the trigger 11, the coordinate detection means 6 calculates reference point coordinates based on the image transmitted from the model gun 10, and the screen 1a indicated by the player based on the reference point coordinates. The indicated coordinates, which are the above coordinates, are obtained.

  The designated coordinates obtained as described above are transmitted to the control means 5, and the control means 5 compares whether or not the coordinates of the target at the moment when the player pulls the trigger 11 matches the designated coordinates. Therefore, it will be judged whether the target is right.

  However, in the conventional shooting game machine as described above, one or more reference points generated by the infrared generator 4 are distributed near the image without any special rule, and the model gun 10 rotates. There is a problem that accurate position calculation cannot be performed because the player's designated coordinates are detected based on this assumption.

とし（ＣＣＤカメラの座標の原点は左側上側角部と仮定する）、スクリーン１ａ上でのスクリーン１ａの中心の座標は

であって、予め格納されている）、前記の参考点が全て前記ＣＣＤカメラ１３に感知される場合にのみ指示座標の検出を行う。 That is, as shown in FIG. 4a, the conventional shooting game machine is arranged so that two normal reference points are symmetric with respect to the center of the screen 1a, and each coordinate on the CCD camera 13 is

(Assuming that the origin of the coordinates of the CCD camera is the upper left corner), the coordinates of the center of the screen 1a on the screen 1a are

However, the designated coordinates are detected only when the CCD camera 13 senses all the reference points.

を各々計算して、更に重心を求める方法により参考点の中心（参考点をスクリーン１ａの中心に対称になるように配置するので、参考点の中心はスクリーン１ａの中心となる）のＣＣＤカメラ１３上での座標

を計算する。前記ＣＣＤカメラ１３上での参考点の距離ｄは

で求められるので、前記ＣＣＤカメラ１３上の前記ＣＣＤカメラ１３の中心の座標を

とし、前記スクリーン１ａ上での参考点間の距離がＬのとき、指示座標（Ｘ、Ｙ）は

で求められる。 The coordinate detecting means 6 is a coordinate of the reference point on the CCD camera 13.

And the center of the reference point (by arranging the reference point so as to be symmetrical with the center of the screen 1a, the center of the reference point is the center of the screen 1a). Coordinates on

Calculate The distance d of the reference point on the CCD camera 13 is

The coordinates of the center of the CCD camera 13 on the CCD camera 13 are

When the distance between the reference points on the screen 1a is L, the designated coordinates (X, Y) are

Is required.

  Therefore, in the conventional shooting game machine, when the player moves the model gun 10 too close to the screen 1a or away from the center of the screen 1a (when all the reference points are not detected by the CCD camera 13), the accurate pointing coordinates are used. In addition, the method of calculating the indicated coordinates without considering the rotation of the model gun 10 is adopted, and when the rotation of the model gun 10 is considered as in the present invention, the indicated coordinates are set. Since it is not possible to seek, it is not possible to provide a game with a real feeling.

  In addition, since the conventional shooting game machine uses all the reference points displayed to detect the designated coordinates 8 designated by the player and detects the designated coordinates by the above-described method, If some of the reference points are not displayed and some of the reference points are not displayed, the designated coordinates cannot be detected.

  In addition, the conventional shooting game machine cannot detect the designated coordinates unless all the reference points used for detecting the designated coordinates of the player are sensed, so that the range that can be sensed using the same size CCD camera is narrow. There are disadvantages.

  Further, in the conventional shooting game machine, depending on the content of the game provided from the control means 5, the game is progressed only by a method in which the player passively reacts and the model gun 10 is rotated. There is a problem that it is not possible to provide a more dynamic game by detecting an action when the distance to the screen 1a is changed and not reflecting it in the game.

  That is, the distance between the model gun 10 and the screen 1a may vary depending on the player, but a player with good physical conditions may shorten the distance and proceed with the game near the screen 1a. Occur. In such a case, the closer the accuracy is, the higher the accuracy is. Therefore, a fair game cannot be played, and anyone should try to play a game with a short distance.

  Further, the CCD camera 13 used in the shooting game machine is not fixed and can be freely moved by the game player. Therefore, even if the same CCD element is used, the image can be detected with a higher resolution. However, the conventional shooting game machine has a problem that the resolution cannot be utilized to the maximum by detecting the designated coordinates based on the distribution of the reference points limited as described above.

That is, in a shooting game machine, the index used for video detection is resolution, but what directly affects such video detection resolution is the resolution of the CCD element of the CCD camera 13. Increasing the resolution of the CCD element is the easiest way to increase the image detection resolution. However, increasing the resolution of the CCD element as much as desired increases the cost of the CCD element and the amount of data transmitted and processing Since the amount of data to be processed increases and a high-speed transmission method and a high-performance processing device are required, there are limitations on cost and technology.

  Also, by arranging a plurality of reference points according to a special rule, the indicated coordinates can be calculated even if only some of the reference points are used, so that a wider range of indicated coordinates can be obtained using a CCD camera of the same resolution. Not only can calculations be performed, but the same range of indicated coordinates can be calculated using a smaller resolution CCD camera.

  The objects, features, and advantages of the present invention having such a configuration can be more easily understood with reference to the accompanying drawings and the following detailed description.

  FIG. 2 is a perspective view of a shooting game machine applied to the present invention.

  The game apparatus box 1 contains parts excluding the model gun 10 constituting the game machine, and the screen 1a displays a video including a target that is the content of the game and a plurality of reference points that serve as a basis for detecting the designated coordinates. The video generator 2 is a device for displaying video content including a game content and a target, and uses a normal cathode ray tube or a projector.

  As described above, the display means for displaying the target includes the screen 1a, the image generator 2, and the semitransparent reflecting mirror 3. The display means uses the screen 1a and the semitransparent reflecting mirror 3. Instead, the image generator 2 can be directly installed at the position of the screen 1a in FIG.

  The infrared ray generating device 4 uses an infrared laser or the like as a reference point display means which is a device for generating a reference point serving as a basis for detecting the coordinates of a point designated by the player, that is, the designated coordinates, and the screen 1a It is arranged in the vicinity, that is, the inner or outer boundary or the rear surface of the screen 1a.

  The reference point generated by the reference point display means is displayed in the screen 1a or on the boundary line and becomes the basis for coordinate detection as will be described later.

  The reason why the infrared ray generator 4 is used as the reference point generating device is that the game image displayed on the screen 1a is an electromagnetic wave in the visible light region. Is difficult to distinguish from the video of the game, and by using infrared rays to display the reference point, as will be described later, if it is transmitted through the infrared transmission filter 15, it is more accurate and clear. This is because the reference point can be detected.

  Furthermore, in the present invention, as will be described later, since coordinates are calculated using reference points arranged at intervals determined by special rules, unnecessary detected points other than the reference points can be removed. More accurate indication coordinates can be detected.

  The infrared ray generator 4 is preferably arranged on the rear surface of the translucent reflecting mirror 3 and adjusted so that the reference points 7 are arranged on the horizontal axis at the center of the vertical axis of the screen 1a. The reference point of the infrared ray generated from the infrared ray generator 4 is displayed on the screen 1a after passing through the semitransparent reflecting mirror 3. When the display means is replaced by directly installing the image generator 2 at the position of the screen 1a in FIG. 2 without using the screen 1a and the translucent reflecting mirror 3, the infrared ray generator 4 includes the screen 1a. It is provided at or near the boundary line 1a.

  The control means 5 transmits an image including the target to the image generator 2 so that the player can view the game image, and changes the content of the game according to the action of the player, It is a means for controlling the whole of the shooting game machine by determining the propriety and advancing the game. The control means 5 can be realized using a normal microprocessor.

  The model gun 10 is an instruction means that points to a point indicated by the player facing the screen 1a, and the instruction means can be replaced with a model tennis racket, a baseball stick, a command stick, a stick, a sword, or the like.

  The model gun 10 includes a CCD camera 13, a lens 14 and an infrared transmission filter 15. The model gun 10 recognizes that the player has fired the model gun 10 and an image detection unit that detects an image of an area indicated by the instruction unit. A trigger 11 is included. The CCD camera can be replaced with a CMOS semiconductor element that can detect an image.

  The infrared transmission filter 15 performs a function of receiving a game image including a target displayed on the screen 1a, removing light in the visible light region, and allowing only electromagnetic waves in the infrared region to pass.

  A reference point composed of electromagnetic waves in the infrared region that has passed through the infrared transmission filter 15 is imaged on the CCD camera 13 by the lens 14, and the reference point imaged on the CCD camera 13 is converted into an electrical signal for communication. It is transmitted by the coordinate detection means 6 through the line 16.

  The coordinate detection means 6 is a reference point coordinate detection means for detecting the coordinates of the reference point using a signal detected by the video detection means and transmitted through the communication line 16, and a reference detected by the reference point coordinate detection means. Based on the point coordinates, it is composed of designated coordinate detecting means for detecting designated coordinates designated by the player using the designated means. The coordinate detection means 6 includes means for converting the signal transmitted from the model gun 10 into a digital signal when the signal is an analog signal.

  The coordinate detection means 6 can always detect the designated coordinates in order to change the contents of the game according to the player's movement change during the game, while the control means 5 and the coordinate detection means 6 In order to reduce the burden on the operation, the designated coordinates can be detected only at the moment when the trigger 11 is pulled.

  The designated coordinates of the point designated by the player detected by the designated coordinate detection means are transmitted to the control means 5 and compared with the same position as the target position coordinates when the player pulls the trigger 11. Will determine if the player has hit the target.

  The arrangement of the reference points according to the present invention is as follows.

  Conventionally, in shooting game machines, one or two reference points are used, and even when three or more reference points are used, they are arranged at a uniform interval near the screen. Since the ratio of the reference point distance is used for the minimum, the resolution of the screen 1a, the resolution and the visible range of the CCD camera (the range of the screen 1a that the CCD camera can detect at a time) and rotation are selected. Arranged at a predetermined interval in consideration of conditions such as limits (maximum rotation angle at which a minimum of three reference points can be recognized when referring to an image) and the maximum range of gun resolution that the model gun 10 can sense the screen. To do.

  In the present invention, in order to more accurately detect the coordinates of the reference point, the step of distinguishing the actual information of the detected reference point, that is, the specific reference point of the detected reference point, and The step of detecting the designated coordinates using the detected reference point is divided into the steps of detecting the designated coordinates. In order to distinguish the specific reference point of the detected reference point, the CCD camera 13 is the lowest. It must always be possible to detect two distances, ie a minimum of three reference points. It is not necessary to detect all reference points. Therefore, coordinates can be detected using a low-resolution CCD camera 13.

  In order to always detect at least three reference points among a plurality of reference points, the resolution of the CCD camera 13 (if the distance between the reference points is long, a high resolution CCD camera must be used. A low-resolution CCD camera can be used if the distance is short), and the rotation limit of the CCD camera 13, the resolution of the gun and the resolution of the screen 1a, and the progress of the game The reference points are determined so that the intervals between the reference points are determined in consideration of the position where the game player is mainly standing (hereinafter referred to as “standard position”), and the reference points are displayed accordingly. Adjust the display means.

  For example, when the rotation limit of the CCD camera 13 is limited to 30 °, the entire screen 1a can be sensed at a rotation angle within 30 °, but if it is rotated by 30 ° or more, a minimum of 3 at the end of the screen 1a. Two reference points are not detected at the same time. Further, when the reference position is arbitrarily selected by selecting the standard position, if the pointing means is close to the standard position, the ability to decompose the image of the CCD camera 13 is enhanced. It becomes impossible to measure the end portion of the screen 1a. On the other hand, if the position of the pointing means is far from the standard position, the ability of the CCD camera 13 to decompose the image is lowered.

  Actually, the size of the screen 1a can be varied, and the standard position is proportional to the actual size of the screen 1a. Therefore, the resolution of the CCD camera, the visible range and the rotation limit, and the resolution of the gun can be reduced. Based on this, the arrangement interval of the reference points is determined, thereby creating a constant that determines the size and standard position of the screen 1a. For example, when the standard position is 150 cm on the 29-inch screen 1a, the standard position is 258 cm on the 50-inch screen 1a. By such a method, the arrangement of arbitrary reference points always shows the same effect with respect to various sizes of the screen 1a.

  Also, the greater the difference in distance between reference points, the easier it is to identify what reference points are detected.

  By arranging the reference point display means outside the boundary line of the screen 1a, the plurality of reference points can be displayed near the boundary line of the screen 1a, but as shown in FIG. It is preferable to arrange the reference point display means on the rear surface of the translucent reflecting mirror 3 so that it is displayed inside the screen 1a.

  This is because, when the plurality of reference points are arranged outside the screen 1a, as shown in FIG. 3a, the CCD is attached to the model gun 10 and detects an image of an area designated by the player. Since the camera 13 must be mounted so as to be displaced from the barrel 10a, the design of the model gun 10 is limited, but when the plurality of reference points are displayed inside the screen 1a together with the present invention. As shown in FIG. 3b, the CCD camera 13 is attached in a direction that coincides with the barrel 10a, so that the restriction on the design of the model gun 10 is removed.

  The restriction of the reference point arrangement as described above can be accurately expressed through the following mathematical formula (as shown in FIG. 4b, a plurality of reference points are arranged in a straight line in the center of the vertical axis of the screen 1a. Take the example of placement).

  That is, the limit error (ET) at the boundary which is the minimum distance for the minimum three reference points to exist from the boundary of the screen 1a (or the boundary of the region where the image is to be detected) to a certain distance, and the screen 1a. When the CCD camera 13 detects the area inside the screen 1a (or the area inside the area where the video is to be detected) that does not include the boundary (or the boundary of the area where the video is to be detected), A general limit error (GT), which is the minimum distance for detecting a minimum of three reference points, can be mathematically calculated.

と定義すれば、

の公式（その際、ＥＴ（θ）の右側の条件の２つ以上が同時に満足すると、上側の条件により結果が算出される）により算出された値中、最小値がＥＴ及びＧＴの値となる。もし、θ（０≦θ≦θＣ）において、ＥＴ（θ）及びＧＴ（θ）値が全て算出されないと（ｎｏｔ−ｄｅｆｉｎｅｄ）、ＥＴ及びＧＴは存在しなくなる。 The horizontal values gun resolution _(not used because it is a case of displaying a reference point in the horizontal axis) S _W, the vertical values gun resolution S _H, the horizontal value of the CCD camera resolution C _W, the CCD camera When the vertical value of the resolution is C _H , the rotation limit angle of the CCD camera is θ _C , and the rotation angle of the CCD camera is θ (0 ≦ θ ≦ θC),

Defined as

Among the values calculated by the formula (when two or more of the conditions on the right side of ET (θ) are satisfied at the same time, the result is calculated by the upper condition), the minimum value is the value of ET and GT . If all the ET (θ) and GT (θ) values are not calculated in θ (0 ≦ θ ≦ θC) (not-defined), ET and GT do not exist.

  The distance between the reference points is set as large as possible within a range that satisfies the ET and GT conditions calculated as described above. For example, if the limit angle is 15 °, the ET is 58.58 and the GT is 142.99, so a minimum of three reference points are placed within a distance of 58.58 from the screen boundary, All three reference points are arranged within a distance of 142.99, and the reference points are arranged so as to have the maximum distance.

  More accurate coordinate calculation is possible by arranging reference points based on numerical values calculated mathematically by the resolution and visible range of the CCD camera 13, the resolution of the gun, the resolution of the screen 1a and the standard position as described above. It is.

  FIG. 8a is a block diagram for explaining a method of using a CCD camera according to an embodiment of the prior art, and FIG. 8b is a diagram for explaining a method of using a CCD camera according to an embodiment of the present invention. FIG.

  Practical, mass-produced, and commonly used CCD elements are manufactured at 4: 3 so as to match the vertical and horizontal ratios of TVs, monitors, etc. (320 × 240, 352 × 288, 400 × 300, 640 × 480, etc.), a CCD element having a resolution of 360 × 240, 720 × 480, etc., in which the horizontal pixels are slightly larger than the vertical pixels may be used.

  Taking a CCD element with a resolution of 320 × 240 as an example, a model gun 10 used in a conventional shooting game machine uses a horizontal axis with more pixels arranged in the horizontal direction as shown in FIG. 8a. Therefore, the resolution of the gun that can detect the image at maximum (hereinafter referred to as “image detection resolution”) was only 320 × 240.

  However, as shown in FIG. 8b, when the horizontal axis having a larger number of pixels is used in the vertical direction according to the embodiment of the present invention, that is, when the CCD element is rotated 90 degrees, Since the reference points are densely arranged on the horizontal axis 1a according to a special rule, the video detection resolution 80 on the horizontal axis is not a problem. Therefore, the horizontal resolution is the resolution of the general screen 1a. If 4: 3 is applied, the result is 427 (320 × 4/3).

  Therefore, even if the conventional CCD element is used as it is, the resolution can be improved by (427 × 320) / (320 × 240) = 136, 640/76, 800 = 178%. The resolution can be improved by about 178%.

  In the following, the operation of the embodiment of the present invention will be considered based on the above configuration.

  FIG. 6 is a flowchart of the entire system according to the embodiment of the present invention.

  When the player points to the target displayed on the screen 1a with the model gun 10 (S00, S01), a reference point is detected by the CCD camera 13 provided on the model gun 10 ( S02).

  The reference point detected by the CCD camera 13 is transmitted to the coordinate detection means 6 through the communication line 16, and the point that disturbs the reference point in the transmitted signal is removed by the coordinate detection means 6 (S03). ). Since the information about the position of the reference point is recorded in advance in the game machine, the point to be disturbed is removed in advance, so whether the detected point is a reference point or not is disturbed. It is possible by judging whether the point is to be made.

  After the process of removing the disturbed points (S03), it is determined whether the number of remaining points is 3 or more (S04). This is because the detection of coordinates according to the present invention is possible only when the number of detected reference points is three or more.

  If the number of remaining points is three or more, the instruction coordinates calculated by the coordinate calculation algorithm described later, the distance between the screen 1a and the player, and the rotation angle of the model gun 10 are calculated (S05). If the number is less than 3, return to the beginning.

  The indicated coordinates calculated as described above, the distance between the screen 1a and the player, and the rotation angle of the model gun 10 are transmitted to the control means 5 and reflected in the content of the game, such as the image and the size of the target.

  Next, it is determined whether the player has pulled the trigger 11 (S06). If not, the process returns to the beginning. If the player pulls the trigger 11, the target coordinate 8 at that time is compared with the target coordinate to determine whether or not the target is hit (S07). Finally, it is determined whether or not the game can be ended. If no end signal is detected, the process returns to the beginning (S08).

  The coordinate calculation algorithm for calculating the designated coordinates, the distance between the screen and the player, and the rotation angle of the model gun 10 is as follows.

  FIG. 7 is a block diagram of a coordinate calculation algorithm according to an embodiment of the present invention.

  The screen 1a has a resolution that can be attached with coordinates from 0 to 400 in the horizontal axis direction. The resolution of the CCD camera 13 to be used is 320 × 240, and the side with the larger resolution is arranged in the vertical direction. (Therefore, the coordinates of the center on the CCD camera are (120, 160)), and the reference points are (19, 43, 58, 141, 175, 200, 225, 259, 342, 357, 381). A description will be given as an example of being arranged at a position.

  The position of the reference point is stored in advance in the game machine, and the interval between adjacent reference points in the above example is (24, 15, 83, 34, 25, 25, 34, 83, 15, 24), The ratio of the spacing between adjacent reference points is (0.625000, 5.533333, 0.409638, 0.735294, 1.000000, 1.3600000, 2.441176, 0.180722, 1.60000). .

  The process of detecting coordinates by the player pointing and rotating the model gun 10 toward the screen 1a is performed when the number of reference points input through the CCD camera 13 is three or more. Only starts (S001).

  First, when the number of input reference points is three or more, the distance between each reference point is calculated (S002).

  When the distance between the adjacent reference points is calculated, the ratio of the intervals between the adjacent reference points is sequentially obtained based on the calculated distance (S003).

  After calculating the ratio of the intervals between the adjacent reference points, if there are three input reference points, the reference point at the position having the optimum ratio to the given interval ratio is found (S003, S015). . In the above example, if three reference points are input and the distance ratio is 0.42, 0.409638 is the closest value, so the detected reference points are the third, fourth and fifth reference points. Is considered.

  If there are four or more input reference points, the reference point at the position where the total error with respect to the given interval ratio is the smallest is found (S003, S025). In the above example, if five reference points are input and the distance ratio is sequentially 0.74, 1.33, 2.42, three consecutive reference points are sequentially extracted in the distance ratio. When the comparison is made, the smallest error (average of the absolute value of the difference) is 0.735294, 1.3600000, 2.441176, so the detected reference points are the fourth, fifth, sixth, and seventh. It becomes a reference point.

  At that time, even if a part of the reference point display means fails and the seventh reference point is not displayed, the fourth, fifth and sixth reference points are detected, so that coordinates can be calculated. is there.

  The reference point coordinates are detected by the reference point coordinate detection means based on the reference points detected as described above, and the designated coordinates of the point designated by the player are obtained by the following method (S006).

  There are two reference points used for coordinate calculation. When three reference points are detected, the left two reference points are used for coordinate calculation. When four or more reference points are detected, The indicated coordinates are preferably calculated using two reference points including a reference point closest to the center of the CCD camera 13 and a reference point adjacent thereto.

The predefined values corresponding to each reference point are I ₁ and I _{2 according} to the order,

It is calculated | required by calculating to. In this case, the calculation formulas for the X coordinate and the Y coordinate are calculated after assuming that the lamps are arranged in the center. If the lamp array is not in the center of the monitor, the formula may change.

Assuming that the origin of the coordinates on the screen 1a is the intersection of the extension line of the reference point and the left side of the screen 1a, the predefined values I ₁ and I ₂ are the values of the horizontal axis of the reference point on the screen 1a. Coordinates are preferred. For example, when the designated coordinates are calculated using the third and fourth reference points, the values of I ₁ and I ₂ are 58 and 121, respectively.

（ｒａｄｉａｎ）により計算され、

の符号が正（＋）であれば右に回転したものであり、負（−）であれば左に回転したのである。 As described above, after calculating the instruction coordinates designated by the player, the degree of inclination of the instruction means is calculated based on the coordinates of the found reference points and the coordinates of the reference points inputted in advance. Thus, the rotation angle of the instruction means is obtained (S007). The rotation angle is

(Radian),

If the sign of is positive (+), it is rotated to the right, and if it is negative (-), it is rotated to the left.

  After obtaining the rotation angle of the pointing means, the distance of the found reference point on the CCD camera 13 and the actual distance between the reference points on the screen 1a obtained from the coordinates of the reference point inputted in advance. Based on the above, the distance between the screen 1a and the indicating means is measured (S008).

として求められる。 The distance on the CCD camera 13 of the reference point found as the distance between the screen 1a and the pointing means is D and d, respectively, and is obtained from the focal length of the lens 14 and the coordinates of the reference point inputted in advance. If the distance between the reference points is f and L, respectively, the distance (D) between the screen 1a and the indicating means is

As required.

  FIG. 10 shows a process for changing the difficulty level under a certain condition or the situation in the game according to the distance (D) between the screen 1a and the instruction means thus obtained.

  Referring to FIG. 10, first, the player attempts to fire the model gun 10 while aiming at a target on the screen 1a (S100). At that time, the shooting impactor itself continuously measures the distance (D) from the screen 1a while changing the position of the model gun 10 (S102).

The shooting hitter determines whether or not the measured distance (D) is properly maintained (S103). That is, as shown in FIG. 9, although the distance at which the screen 1a and the instruction means are separated may change depending on the operation of the player, the appropriate distance is defined as the reference point distance (D ₀ ). At this time, when the reference point distance (D ₀ ) is a distance having a predetermined displacement that is not one of the points, the displacement range is set as D _{0a to} D _0b . As a result of measuring and determining the distance (D), if the size is within the displacement range, the normal state is maintained and a normal game is provided (S104). In other words, as shown in FIG. 9, the distance is a distance (D ₁ ) close to the screen 1a or a distance (D ₂ ) farther than the reference point distance (D ₀ ). The difficulty level of the game or the situation in the game is changed (S105). In other words, the game environment of different conditions is provided depending on the distance of the model gun 10, thereby making the player interested in the game.

  Specific embodiments for changing the difficulty level of the game or the situation in the game are disclosed in FIGS. 11a to 11e. FIGS. 11a to 11e are flowcharts illustrating various examples for changing the difficulty / in-game situation of FIG.

ｄ_Ｓ：模型銃とスクリーンとの臨界距離
ｋ：模型銃により値が設定される定数 First, referring to FIG. 11a, the distance (D) and the displacement range (D _{0a to} D _0b ) are determined (S110), and the distance (D) is smaller than the displacement range, that is, a model. position gun 10 is closer than the displacement range (e.g., the position of the _{D 1)} to be in, player when pulling the trigger 11, to increase the dispersion of the bullet (S 111). That is, it does not reach the aiming target and hits a coordinate deviated in an arbitrary direction. This has the effect of reducing the probability of being hit by the target when the player shoots the model gun 10. In that case, a completely different target outside the target may be hit. A formula for a specific example is provided below, and a drawing for it is disclosed in FIG. 12A shows the trajectory of a bullet when only the pure error angle (δ _S ) of the model gun 10 exists, and FIG. 12B shows a shooting game in addition to the pure error angle (δ _S ). It is drawing which shows the error angle ((delta) ₁ ) when a machine forms the variation of a bullet. A formula that exemplifies this is disclosed below, and this formula is merely an illustrative example, and various modifications are possible.

δ _S : Error angle that the model gun basically has d _S : Critical distance between the model gun and the screen k: Constant whose value is set by the model gun

  On the contrary, if the distance (D) is larger than the displacement range, the accuracy of the bullet is increased (S112). In other words, even if a bullet hits a point away from the target, it can be determined that it was hit.

Ｌ′：縮小された大きさ
ｄ_Ｓ：模型銃とスクリーンとの臨界距離
ｋ：物体により設定される定数 Referring to FIG. 11b, the distance (D) and the displacement range (D _{0a to} D _0b ) are determined (S120), and if the distance (D) is smaller than the displacement range, the player activates the trigger 11. When pulling, the target size is reduced (S121). That is, adjusting the size of the target in proportion to the distance of the model gun 10 provides the same or worse conditions without changing position, which reduces the probability of hitting the bullet target. Let An exemplary mathematical formula for it is disclosed below.

L ′: reduced size d _S : critical distance between model gun and screen k: constant set by object

  On the contrary, if the distance (D) is larger than the displacement range, the size of the target is increased to increase the accuracy of the bullet (S122).

Referring to FIG. 11c, the distance (D) and the displacement range (D _{0a to} D _0b ) are determined (S130), and if the distance (D) is smaller than the displacement range, the player activates the trigger 11. When drawing, a penalty is given to the player (S131). As an example of the penalty, the player's movement speed in the game environment is significantly reduced for a certain period of time so that it can not be easily adapted to the game environment or the height is limited when jumping in the game environment Of course, various examples can be applied, such as increasing the firing interval so that continuous firing is not easy, and increasing the moving speed of the target so that the player cannot easily track . On the other hand, if the distance (D) is larger than the displacement range, the player can be provided with a normal game that is not different from normal (S132), or can be given an advantage.

  Referring to FIG. 11d, the distance (D) and the displacement range (D0a to D0b) are determined (S140). If the distance (D) is smaller than the displacement range, the screen size shown on the screen 1a is determined. The size is reduced (S141). This has the effect of reducing the field of view of the target as it is fired, and the size of the target should be reduced accordingly. On the contrary, if the distance (D) is larger than the displacement range, the target size is enlarged (S142). In other words, the player's activity can be ensured by increasing the size of the target in proportion to the increasing distance. An example for this is shown in FIG. FIG. 13A shows the size (h1) of the screen shown on the screen 1a when the model gun 10 is far away from the screen 1a, and FIG. The screen size (h2) when it is located closer to the screen 1a than the reference point distance is shown.

Referring to FIG. 11e, the distance (D) and the displacement range ( _{D0a to D0b} ) are determined (S150). If the distance (D) is smaller than the displacement range, the player triggers. When 11 is drawn, the situation in the game is changed (S151). The situation in the game means that the arrangement of the set shown on the screen is changed or the background is changed, and this causes the player to have an indirect influence on the game. On the other hand, if the distance (D) is greater than the displacement range, leave the set and background intact and more clearly represent the target outline so that the player can aim better. (S152).

  Thus, according to the present invention, the player can accurately calculate the pointing means, that is, the point to be pointed toward the screen 1a with the model gun 10, and the rotation of the model gun 10 is taken into consideration. In addition, precise calculation of the indicated coordinates is possible.

  In addition, the method of sensing the designated coordinates according to the present invention can calculate the designated coordinates even when the CCD camera 13 senses only a part of the reference points. Therefore, as shown in FIG. Even if the CCD camera 13 is used, it is possible to sense a wider range of designated coordinates, and to use the smaller resolution CCD camera to calculate the same range of designated coordinates.

  Further, when a part of the reference point display means breaks down and some reference points cannot be displayed, the conventional shooting game machine cannot calculate the indicated coordinates as shown in FIG. 5a. However, in the present invention, as shown in FIG. 5b, the point and rotation indicated by the player even if some of the infrared ray generators 4 fail and some reference points cannot be displayed, and the screen 1a and the indication Since the distance between the means can be calculated, the durability of the shooting game machine is further increased.

  Further, the present invention can calculate the degree of rotation of the instruction means and the distance between the screen 1a and the instruction means, and the control means 5 adjusts the difficulty level of the game based on this, and also displays the video. Active and can change. That is, when the player approaches the screen 1a, the target can be easily hit by the target. Therefore, the control means 5 increases the difficulty of the game by increasing the speed at which the target moves or by reducing the size of the target. On the other hand, if the player moves away from the screen 1a, the difficulty of the game can be lowered by decreasing the moving speed of the target or increasing the size of the target.

  In addition, the conventional shooting game machine has progressed the game regardless of the movement of the player. However, the control means 5 of the present invention allows the player to rotate or move the instruction means or to determine the degree of proximity to the display means. Or change the video of the game.

  Accordingly, the player can enjoy a game in which the difficulty level and progress change in response to the player's own movement, and thus, a more realistic shooting game can be enjoyed.
