Disclosure of the invention

[0004] In a baseball game in which the action screen of a player character photographed by the conventional virtual camera is displayed on a monitor, the camera position of the virtual camera and the gazing point of the virtual camera are set in advance for each player character or event. This makes it possible to capture the action of the player character with the optimal camera angle that matches each player character or event. Specifically, when shooting a series of actions when the batter character enters the batter box with the virtual camera, the camera position of the virtual camera is set to the front of the stand, and the gaze point of the virtual camera is set to the batter character's face position. By setting it, the batter character's movement will be shot with the optimal power mela angle!

[0005] However, in a real-world baseball broadcast, when a TV camera shoots a baseball player, the TV camera shakes up and down due to, for example, the influence of the wind generated in the stadium or an erroneous operation of the cameraman, resulting in a TV screen. The projected baseball player may swing up and down. On the other hand, in the conventional baseball game, the camera position of the virtual camera and the gazing point of the virtual camera are set in advance to be constant values for each player character or event that is the object to be photographed. Therefore, it is impossible to reproduce the shaking of a TV camera in a real-world baseball broadcast, so it is close to a real-world baseball broadcast! It is very difficult to realize a realistic baseball game.

[0006] An object of the present invention is to realize a realistic game in a game program.

[0007] A game program according to claim 1 is a program for causing a computer capable of realizing a game for displaying a motion screen of a character photographed by a virtual camera on a monitor to realize the following functions.

(1) A reference character data creation function for creating reference character data relating to a character photographed by a virtual camera. [0009] (2) A reference camera gazing point data creation function for creating reference camera gazing point data for a character to be photographed by a virtual camera.

[0010] (3) A game condition determining function for determining whether or not a predetermined game condition regarding the game is satisfied.

[0011] (4) A camera gazing point that creates camera gazing point data of a virtual camera based on the reference camera gazing point data when the game condition deciding function determines that a predetermined game condition is satisfied. Data creation function.

[0012] (5) A character data creation function for creating character data relating to a character based on the reference character data and the camera gazing point data.

[0013] (6) A character motion display function that reads character data created by the character data creation function and displays a motion screen of the character photographed by the virtual camera.

[0014] In the game realized by this program, the reference character data relating to the character photographed by the virtual camera is created by the reference character data creation function. In the reference camera gazing point data creation function, reference camera gazing point data for the character to be imaged by the virtual camera is created. In the game condition determining function, it is determined whether or not a predetermined game condition relating to the game is satisfied. In the camera gaze point data creation function, when the game condition judgment function determines that a predetermined game condition is satisfied, virtual camera camera gaze point data is created based on the reference camera gaze point data. The In the character data creation function, character data related to the character is created based on the reference character data and the camera gazing point data. In the character motion display function, the character data created by the character data creation function is read, and the motion screen of the character photographed by the virtual camera is displayed.

For example, consider a case where a baseball game in which a player character is operated is realized. Here, in a baseball game, a player character that is a target object such as a pitcher character or a batter character, for example, a pitcher motion of a pitcher character or a batter character photographed by a plurality of virtual cameras placed behind the back net or in front of a stand. Action to perform the blow action Play a game that displays the screen on the monitor.

First, reference character data relating to a character photographed by the virtual camera is created by the reference character data creation function. Here, the reference character data related to the character is data used as a reference for generating the motion performed by the player character as a moving image, and is basic data that does not depend on the shaking of the virtual camera described later. .

Next, reference camera gazing point data for a character to be imaged by the virtual camera is created by the reference camera gazing point data creation function. Here, the reference camera gazing point data related to the character is a point that actually exists! /,!, And the virtual camera focuses on the target character. The straight line extending straight toward is the numerical data of the point on the character that intersects the character, for example, the numerical data of the three-dimensional coordinate position on the character. Specifically, when shooting a series of actions when the batter character enters the batter box with the virtual camera, the reference camera gaze data creation function sets the gaze point of the virtual camera to the batter character's face position. Then, the numerical data of the three-dimensional coordinate position of the batter character's face position is created as the reference camera gazing point data for the character.

Next, it is determined by the game condition determination function whether or not the power satisfies a predetermined game condition related to the game. Here, the predetermined game condition is a specific condition in which the virtual camera is shaken, and is a specific condition in which the virtual camera is shaken due to, for example, an influence of a wind generated in the stadium or an erroneous operation of a cameraman. In the game condition determination function, when a predetermined game condition is satisfied, specifically, when the wind force generated in the stadium is higher than a predetermined value or when the cameraman makes an erroneous operation according to the probability that the cameraman makes an erroneous operation. When it is determined that the virtual camera has moved, the virtual camera swings up and down by a predetermined amount (swing width), for example, in the predetermined swing direction, which is the shake data of the virtual camera, and the coordinate position of the X-axis and Z-axis It is determined that the virtual camera has shaken so that the numerical data at the coordinate position of the Y axis is increased or decreased by a predetermined amount while the numerical data is maintained. If the predetermined game condition is not satisfied, it is determined that the virtual camera is shaken.

Next, when it is determined by the camera gazing point data creation function that the predetermined game condition is satisfied by the game condition determination function, based on the reference camera gazing point data, Camera gazing point data of the virtual camera is created. Here, the camera gazing point data relating to a character is a point where a virtual camera that does not actually exist focuses on the target character, and the virtual camera power also extends straight toward the character. Is the numerical data of the point on the character that intersects the character, for example, the numerical data of the three-dimensional coordinate position on the character. The camera gazing point data relating to the character is data depending on the shaking of the virtual camera in which the shaking data of the virtual camera is added to the reference camera gazing point data relating to the character. Specifically, the game condition determination function causes the virtual camera to swing up and down by a predetermined amount (swing width) in a predetermined swing direction that is the shake data of the virtual camera, for example, the X axis and Z axis. If it is determined that the virtual camera shakes so that the numerical data at the coordinate position of the Y axis is increased or decreased by a predetermined amount while maintaining the numerical data at the coordinate position of the camera, the camera gaze data creation function causes the virtual camera Numerical data is created for the three-dimensional coordinate position where the viewpoint swings up and down the batter character's face. Here, for example, the helmet position increased by a predetermined amount upward from the face position is created, and numerical data of the three-dimensional coordinate position of the batter character's helmet position is created as the camera gaze data related to the character. Is done. The uniform position is increased by a predetermined amount downward from the face position, and numerical data of the three-dimensional coordinate position of the batter character's uniform position is created as camera gaze data for the character.

Next, character data relating to the character is created by the character data creation function based on the reference character data and the camera gazing point data. Here, the character data relating to the character is data for generating the motion performed by the player character as a moving image, and is data depending on the shaking of the virtual camera to which the shaking data of the virtual camera is added. Specifically, based on the reference character data related to the character created by the reference character data creation function and the camera gaze data of the virtual camera created by the camera gaze data creation function, for example, the virtual camera The batter character photographed by the virtual camera with the viewpoint set to the helmet position where the face position increased upward by a predetermined amount or the helmet position where the viewpoint decreased downward from the face position by a predetermined amount was added. A series of operation screens when entering the utter box Data for generation is created.

[0021] Then, the character motion display function reads out the character data created by the character data creation function, and the motion screen of the character photographed by the virtual camera is displayed. Here, the helmet position created by the character data creation function, for example, the helmet position where the gazing point of the virtual camera has increased by a predetermined amount upward from the face position, or the uniform position where the facial position force has been increased by a predetermined amount downward The batter shot by the virtual camera with the shaking is read, and the data for generating a series of action screens when the batter character shot by the virtual camera with the shaking added is entered into the knotter box. A series of operation screens when the character enters the batter box is displayed on the monitor.

[0022] In this game program, the reference character data creation function and the reference camera gazing point data creation function allow the reference character data regarding the character photographed by the virtual camera and the reference camera gazing point data for the character to be photographed by the virtual camera. Data is created. Next, when the game condition determination function determines that the wind force generated in the stadium is greater than or equal to a predetermined value, or when the cameraman has determined that the cameraman has made an error due to the probability of the cameraman having made an error, the virtual camera shake data For example, the virtual camera swings up and down by a specified amount of swing (swing width) in the predetermined swing direction, and the coordinate position of the Y axis while maintaining the X and Z coordinate position data. It is determined that the virtual camera has swayed so that the numerical data of is increased or decreased by a predetermined amount. Next, when the game condition determination function determines that a predetermined game condition relating to the game is satisfied, the camera gaze data and character data of the virtual camera are created by the camera gaze data creation function and the character data creation function. Character data for is created. Then, the character motion display function reads out the character data created by the character data creation function and displays the motion screen of the character photographed by the virtual camera.

[0023] Specifically, when shooting a series of actions when a batter character enters a batter box with a virtual camera, the gaze point of the virtual camera determines the face position of the batter character with the reference camera gaze point data creation function. Is set, and numerical data of the 3D coordinate position of the batter character's face position is created as the reference camera gazing point data for the character . Next, with the game condition judgment function, the virtual camera swings up and down by a predetermined amount (swing width) in the predetermined swing direction that is the shake data of the virtual camera, for example, the X-axis and z-axis coordinates When it is determined that the virtual camera has shaken so that the numerical data of the Y-axis coordinate position is increased or decreased by a predetermined amount while the numerical data of the position is maintained, the camera gaze data creation function changes the virtual camera's gaze point to the batter. The numerical data of the three-dimensional coordinate position of the position that swung in the vertical direction of the character's face position is created. Here, for example, the helmet position is increased by a predetermined amount upward from the face position, and the numerical data of the three-dimensional coordinate position of the batter character's hermet position is created as the camera gaze data related to the character. Also, the uniform position is increased by a predetermined amount downward from the face position, and numerical data of the three-dimensional coordinate position of the batter character's uniform position is created as camera gazing point data relating to the character. Next, the character data creation function sets the gaze point of the virtual camera to the helmet position where the gaze point of the virtual camera is increased upward by a predetermined amount or the uniform position where the facial position force is also increased by a predetermined amount of downward. Then, data is generated for generating a series of action screens when the batter character photographed by the virtual camera to which the shaking is added enters the knotter box. Then, with the character action display function, the uniform created by the character data creation function with the virtual camera gaze point increased by a predetermined amount upward from the face position or the uniform increased by a predetermined amount downward from the face position. The data used to generate a series of action screens when a batter character shot by a virtual camera set at a position and shaken enters the notter box is read and shot by a virtual camera with shake added. A series of action screens when the batter character enters the batter box is displayed on the monitor.

Here, if it is determined that the virtual camera is shaken by the game condition determination function, the camera gaze point related to the character that has the virtual camera shake data created by the camera gaze data creation function and the character data creation function. The character data related to the data and the character is created, and a series of operation screens when the batter character photographed by the virtual camera to which the shake is added enters the batter box is displayed on the monitor. Therefore, in this game program, the TV camera shakes like a real-world baseball broadcast. Since it can be reproduced, it is possible to realize a baseball game with a reality close to that of a real-world baseball game.

[Processing flow when executing character action display system and batting result determination system in baseball game]

The character motion display system and the camera gazing point data creation system in the baseball game of the present embodiment are a schematic diagram showing the change in vertical shaking of the virtual camera 80 shown in FIG. 4, and the flowcharts shown in FIG. 9 and FIG. It explains using.

First, the virtual camera 80 swings in the vertical direction as shown in FIGS. The + direction shown in FIGS. 4 and 5 means the upward direction, and the one direction shown in FIGS. 4 and 5 means the downward direction. As shown in FIG. 4, when the virtual camera 80 increases or decreases the numerical data of the Y-axis coordinate position by a predetermined amount while maintaining the numerical data of the X-axis and Z-axis coordinate positions, the virtual camera 80 has a predetermined cycle. The camera gazing point data Ll to Ln are determined so that a waveform having a different amplitude (a maximum or minimum amplitude on the Y axis), such as a waveform of a sine wave, has a different amplitude every 2π. It is summer. Specifically, as shown in FIG. 4, in the period from 0 to 2π, the virtual camera 80 swings upward so that the maximum amplitude becomes +1 at the Α position, and reaches the B position. When the virtual camera 80 is turned over, the virtual camera 80 is turned into a state, and the virtual camera 80 is swung so that the maximum amplitude is 1 in the downward direction at the C position.

Here, the position A shown in FIG. 4 corresponds to the first camera gazing point 41 of the virtual camera 80 in a state where the virtual camera 80 shown in FIGS. 5 and 6 is swung upward, and B shown in FIG. 5 corresponds to the second camera gazing point 42 of the virtual camera 80 in the state, and the C position shown in FIG. 4 corresponds to the virtual camera shown in FIG. 5 and FIG. This corresponds to the third camera gazing point 43 of the virtual camera 80 in a state where 80 is swung downward. In addition, as shown in Fig. 4, in the period up to 2π force 4π, the virtual camera 80 swings in the upward direction so that the maximum amplitude is +3, and the virtual position is The camera 80 is not shaken and is in the F position! The virtual camera 80 is swung so that the maximum amplitude is 3 in the downward direction. In addition, as shown in FIG. 4, in the period up to 4π force 6π, the virtual camera 80 swings upward in the G position so that the maximum amplitude becomes +2, and the virtual camera 80 moves to the Η position. 80 shakes ヽ In this state, the virtual camera 80 is swung so that the maximum amplitude is 2 in the downward direction at the I position. Here, 3 to −1 and +1 to +3 are relative ratios of the amplitude at which the virtual camera 80 swings. For example, the swing of the virtual camera 80 having a period of 2π force or 4π is 0 force 2 The shaking of the virtual camera 80 with a period up to π is three times that of the shaking. Therefore, the first camera gaze point 41 with a period of 2 π force up to 4 π is placed above the position of the first camera gaze point 41 with a period of 0 to 2 π, and the 2 π force 4 π The third camera gazing point 43 with a period up to 2 is arranged at a position below the position of the third camera gazing point 43 with a period from 0 force to 2π, and the shaking of the virtual camera 80 is large. It expresses that.

[0074] In this way, the batting action display screen 40, which is the batting action screen when the batter character 70 photographed by the virtual camera 80 swaying upward and downward enters the batter box, is displayed on the television monitor 20. The character action display system that performs this will be described with reference to the flowchart shown in FIG.

First, the camera position data Ρ1 to Ρη of the virtual camera 80, which actually exists but is the position where the virtual camera 80 is arranged, are created (Sl). In the camera position data creation process of step SI, camera position data Pl to Pn of the virtual camera 80, which is position data determined by the three-dimensional coordinate position in the stadium, are created. Specifically, when the virtual camera 80 is placed in front of the stand, the camera position P1 of the virtual camera 80 is set in front of the stand, and the numerical data of the three-dimensional coordinate position of the camera position P1 of the virtual camera 80 is Created. Various data of the camera position data P 1 to Pn created by the camera position data creation process of step S 1 is stored in the RAM 12. When the camera position data creation process in step S1 is performed, the process proceeds to the reference character data creation process (S2).

In the reference character data creation process in step S2, reference character data CBl to CBn related to the character photographed by the virtual camera 80 are created. Here, the reference character data CBl to CBn related to the character is data used as a reference for generating the motion performed by the character as a moving image, and is basic data that does not depend on the shaking of the virtual camera 80. Specifically, the reference character data CB1 related to the batter character 70 entered in the knotter box is data for generating a motion of the striking swing of the specific batter character 70 as a movie, and the virtual character data shown in FIG. Camera 80 is not shaken This is data for generating a moving image in which the batter character 70 performs a batting swing motion. Various data of the reference character data CBl to CBn created in the reference character data creation process of step S2 is stored in the RAM 12. When the reference character data creation process in step S2 is performed, the process proceeds to the reference camera gazing point data creation process (S3).

In the reference camera gazing point data creation process in step S3, reference camera gazing point data LBl to LBn for the character to be photographed by the virtual camera 80 are created. Here, the reference camera gazing point data LBl to LBn relating to characters are points where the virtual camera 80 that does not actually exist focuses on the target character, as shown in FIG. , A straight line extending straight from the virtual camera 80 toward the batter character 70 (straight lines connecting the tip of the virtual camera 80 and the first camera gaze point 41, the second camera gaze point 42, and the third camera gaze point 43, respectively) SL1 to SL3) are numerical data of points on the batter character 70 where the batter character 70 intersects, for example, numerical data of a three-dimensional coordinate position on the character. In Fig. 5, a straight line extending straight from the virtual camera 80 placed in front of the stand toward the batter character 70 (the tip of the virtual camera 80, the first camera gaze point 41, the second camera gaze point 42, the third camera This is the numerical data of the points on the batter character 70 where the straight lines SL1 to SL 3) respectively connecting the gazing point 43 and the batter character 70 intersect. Here, the reference camera gazing point data LB1 to LB3 and the first camera gazing point 41, the second camera gazing point 42, and the third camera gazing point 43, which are the camera gazing point data L1 to L3 described later, correspond to each other. In particular, the second camera gazing point 42 that is the camera gazing point data L2 of the virtual camera 80 that is not shaken is the same as the reference camera gazing point data LB2. The various data of the reference camera gazing point data LBl to LBn created in the reference camera gazing point data creation process in step S3 is stored in the RAM 12. When the reference camera gazing point data creation process in step S3 is performed, it is determined whether or not a predetermined game condition regarding the game is satisfied (S5).

In the game condition determining process in step S5, a predetermined game condition relating to the game, that is, whether or not a specific condition that the virtual camera 80 is shaken is satisfied is determined. Specifically, when the wind power data W of the wind generated in the stadium (see Fig. 3) is greater than or equal to a predetermined value, or when it is determined that the cameraman has made a mistake by the probability that the photographer will make a mistake. Is a predetermined amount of shaking (swing width) that is the shaking data of the virtual camera 80.For example, the virtual camera 80 swings up and down as shown in the schematic diagram of FIG. While maintaining the numerical data of the coordinate position of the Z axis, the virtual camera 80 is adjusted so that the numerical data of the coordinate position of the Y axis is increased or decreased by a predetermined amount (-3 to 1-1, +1 to +3 shown in Fig. 4). It is determined that the camera has shaken, and the process proceeds to the camera gazing point data creation process (S5). In the game condition determination process in step S5, if the predetermined game condition is not satisfied, it is determined that the virtual camera 80 is shaken! And the process proceeds to the character action display process (S7).

As shown in FIG. 10, the camera gazing point data creation process in step S5 is performed by reading the reference camera gazing point data LB1 to LBn created in the reference camera gazing point data creation process in step S3 from the RAM 12 (S11). . When the reference camera gazing point data reading process in step S11 is performed, the camera shake data R (see Fig. 3) of the virtual camera 80 is read (S12). O The camera shake data R is a numerical data between 0 and 1. The larger the value, the more the virtual camera 80 shakes. When the camera shake data R in step S12 is read, camera shake random number data ER (see FIG. 3) of the virtual camera 80 is calculated (S1 3). Camera shake random number data ER is numerical data of 0 or more and R or less, and is numerical data of 0 or more and 1 or less calculated by random number calculation. When the camera shake random number data ER is calculated in the camera shake random number calculation process in step S13, the wind power data W is read from the RAM 12 (S14). When the wind data reading process in step S14 is performed, wind influence data EW (see FIG. 3) is calculated (S15). Wind influence data EW is numerical data representing the degree of wind influence calculated by dividing the wind data W by the maximum value of the wind data W, and is numerical data from 0 to 1. When the wind influence data EW is calculated in the wind influence data calculation process in step S15, the camera shake coefficient E (see Fig. 3) is calculated (S16). The camera shake coefficient E is the sum of the camera shake random number data ER calculated in the camera shake random number calculation process in step S13 and the wind influence data EW calculated in the wind influence data calculation process in step S15. Numerical data obtained in this way. When the camera shake coefficient E is calculated in the force camera shake coefficient calculation process in step S16, the camera gazing point data calculation process is performed (S17). In the camera gazing point data calculation process in step SI 7, the reference camera gazing point data L read out in the reference camera gazing point data reading process in step S11 Camera gazing point data Ll to Ln (see FIG. 3) of the virtual camera 80 are created using B1 to LBn and the camera shake coefficient E calculated in the camera shake coefficient calculation process in step S16. Here, in the schematic diagram shown in FIG. 4, the amplitude S of the virtual camera 80 is calculated by the camera shake coefficient calculation process of step S16 to the maximum value of the amplitude S of the virtual camera 80 (D position in FIG. 4). It is obtained by multiplying the camera shake coefficient E. If the amplitude S of the virtual camera 80 exceeds the maximum value of the amplitude S of the virtual camera 80 that does not exceed the maximum value (D position in FIG. 4) of the virtual camera 80, the virtual camera 80 The amplitude S of the virtual camera 80 is the same as the maximum value of the amplitude S of the virtual camera 80. Here, it is obtained by multiplying the numerical data of the Y-axis coordinate position by the amplitude S and sin (T) (T is time) of the virtual camera 80 while maintaining the numerical data of the X-axis and Z-axis coordinate positions. The shaking of the virtual camera 80 having the sin curve shown in Fig. 4 is determined. Note that the camera gazing point data calculation process in step S 17 is repeated every cycle 2 π, and different amplitudes S are obtained every cycle 2 π, so that different sins are obtained every cycle 2 π as shown in FIG. The shaking of the virtual camera 80 that becomes a curve is determined. Various data of the camera gazing point data Ll to Ln created by the camera gazing point data calculation process in step S17 is stored in the RAM 12. When the camera gazing point data Ll to Ln of the virtual camera 80 are created in the camera gazing point data calculation process of step S17, the process proceeds to the character data creation process of FIG. 9 (S6).

In the character data creation process in step S6, camera position data Pl to Pn created by the camera position data creation process in step S1, reference character data CBl to CBn created by the reference character data creation process in step S2, step Character data Cl to Cn related to the character are created based on the camera gazing point data LBl to LBn created by the camera gazing point data creation process of S5. Here, the character data Cl to Cn relating to the characters is data for generating motions performed by the player character as moving images, and the virtual camera 80 to which the camera shake data R and wind power data W of the virtual camera 80 are added. This data is dependent on the shaking. Specifically, the camera position data Pl to Pn created by the camera position data creation process in step S1, the reference character data CB1 to CBn created by the reference character data creation process in step S2, and the camera gazing point in step S5 Camera gazing point created by data creation process Based on the data LB 1 to LBn, the camera gazing point data L 1 to Ln of the virtual camera 80 increased by a predetermined amount upward from the nose position (second camera gazing point 42 shown in FIGS. 5 and 7). Helmet position (first camera gazing point 41 shown in Figs. 5 and 6) or nasal position force is set to the jaw position (third camera gazing point 43 shown in Figs. 5 and 8) decreased by a predetermined amount downward. The virtual camera 80 to which the camera shake data R and the wind power data W of the virtual camera 80 are added generates data for generating a batting action screen when the batter character 70 enters the knotter box. Here, first, in the second camera gazing point 42 of the virtual camera 80 in a state where the virtual camera 80 is not shaken as shown in FIGS. 5 and 7, the reference character data regarding the batter character 70 corresponding to the second camera gazing point 42 is used. Based on CB1, the reference character data C2 relating to the batter character 70 is created. Next, in the first camera gazing point 41 of the virtual camera 80 with the virtual camera 80 swaying upward shown in FIGS. 5 and 6, the reference character data regarding the batter character 70 corresponding to the first camera gazing point 41 Based on CB1, character data C1 related to the batter character 70 is created that performs the same operation as the reference character data CB1 related to the batter character 70 but the virtual camera 80 faces upward. Further, in the third camera gazing point 43 of the virtual camera 80 with the virtual camera 80 swaying downward shown in FIGS. 5 and 8, reference character data CB 1 relating to the batter character 70 corresponding to the third camera gazing point 43 Based on this, the character data C3 relating to the batter character 70, which operates in the same manner as the reference character data CB1 relating to the batter character 70 but the virtual camera 80 is directed downward, is created. Various data of the character data Cl to Cn created by the character data creation processing of step S6 is stored in the RAM 12. When the character data Cl to Cn are created in the character data creation process in step S6, the process proceeds to the character action display process (S7).

In the character action display process of step S7, the character data Cl to Cn created by the character data creation process of step S6 are read, and the action screen of the character photographed by the virtual camera 80 is displayed. In the character action display process in step S7, first, the second camera gazing point 42 of the virtual camera 80 in the state where the virtual camera 80 is not shaken as shown in FIGS. 5 and 7 is created by the character data creation process in step S6. When the recorded character data C2 is read and the batter character 70 photographed by the virtual camera 80 enters the batter box, the batting motion display screen 40 (see FIG. 7) is a television monitor 20. Is displayed. Next, in the first camera gazing point 41 of the virtual camera 80 with the virtual force camera 80 swinging upward as shown in FIGS. 5 and 6, the character data C1 created by the character data creation process of step S6 is The batting motion display screen 40 (see FIG. 6), which is the batting motion screen when the batter character 70 taken by the virtual camera 80 that has been read and shaken upwards enters the knotter box, is displayed on the television monitor 20. Is done. Further, in the third camera gazing point 43 of the virtual camera 80 in a state in which the virtual camera 80 shown in FIGS. 5 and 7 is swung downward, the character data C3 created by the character data creation processing in step S6 is read out. The hitting action display screen 40 (see FIG. 7) is displayed on the television monitor 20 when the batter character 70 photographed by the virtual force mela 80 swaying downward enters the knotter box.

Here, if it is determined that the virtual camera 80 is shaken by the game condition determination process of step S5, the virtual camera 80 is processed by the camera gazing point data generation process of step S5 and the character data generation process of step S6. Camera gazing point data L1 to Ln for batter character 70 to which camera shake data R and wind power data W are added, and character data Cl to Cn for batter character 70 are created, and camera shake data R and wind data W are added. The batting action display screen 40 that is the batting action screen when the batter character 70 photographed by the virtual camera 80 enters the batter box is displayed on the television monitor 20. This game program can reproduce the shaking of a TV camera like a real-world baseball broadcast, so a realistic baseball game similar to a real-world baseball broadcast can be realized.
