  FIG. 1 is a diagram showing a configuration of a game device according to an embodiment of the present invention. The game apparatus 10 shown in the figure is configured by attaching a DVD-ROM 25 and a memory card 28 as information storage media to a consumer game machine 11 and further connecting a monitor 18 and a speaker 22. A monitor that displays a screen by scanning is used as the monitor 18. For example, a household television that displays a scanning line by moving a bright spot in the horizontal direction (left-right direction) at high speed and displays the screen by sequentially shifting the scanning line in the vertical direction (displaying the screen by raster scanning). A receiver is used as the monitor 18. The built-in speaker is used as the speaker 22.

  Here, the DVD-ROM 25 is used to supply the program to the consumer game machine 11, but any other information storage medium such as a CD-ROM or a ROM card may be used. Further, the program may be supplied to the consumer game machine 11 from a remote place via a data communication network such as the Internet.

  The home game machine 11 is a known computer that includes a microprocessor 14, an image processing unit 16, a main memory 26, an input / output processing unit 30, an audio processing unit 20, a gun controller 32, and a DVD-ROM playback unit 24. It is a game system. The microprocessor 14, the image processing unit 16, the main memory 26, and the input / output processing unit 30 are connected by the bus 12 so that mutual data communication is possible. Connected to the input / output processing unit 30 are a gun controller 32, an audio processing unit 20, a DVD-ROM playback unit 24, and a memory card 28. Each component of the consumer game machine 11 other than the gun controller 32 is housed in a housing.

  The microprocessor 14 controls each part of the consumer game machine 11 based on an operating system stored in a ROM (not shown), a program read from the DVD-ROM 25, and save data read from the memory card 28, and allows the player to play a game. I will provide a. The bus 12 is for exchanging addresses and data among the units of the consumer game machine 11. The main memory 26 includes, for example, a RAM, and a program read from the DVD-ROM 25 and save data read from the memory card 28 are written as necessary. The main memory 26 is also used for work of the microprocessor 14. The image processing unit 16 includes a VRAM. The image processing unit 16 receives image data sent from the microprocessor 14, draws a game screen on the VRAM based on the image data, converts the contents into a video signal, and converts the content into a video signal. Output to the monitor 18 at timing.

  The input / output processing unit 30 is an interface for the microprocessor 14 to access the gun controller 32, the sound processing unit 20, the DVD-ROM playback unit 24, and the memory card 28. The sound processing unit 20 includes a sound buffer. The sound processing unit 20 reads out various sound data such as game music, game sound effects, and messages read from the DVD-ROM 25 and stored in the sound buffer, and is output from the speaker 22. Output. The DVD-ROM playback unit 24 reads a program recorded on the DVD-ROM 25 in accordance with an instruction from the microprocessor 14. The memory card 28 includes a non-volatile memory (for example, EEPROM) and is configured to be detachable from the consumer game machine 11. The memory card 28 stores save data for various games.

  The gun controller 32 is a handgun type game controller. The gun controller 32 is used for the player to indicate any position on the screen displayed on the monitor 18 in a non-contact manner according to the direction of the barrel (instruction unit). The gun controller 32 includes a known light detection sensor for detecting light of a predetermined light quantity or more from the barrel direction. Information indicating whether or not light detection is performed by the light detection sensor may be transmitted to the microprocessor 14.

  The gun controller 32 includes a microprocessor, and acquires a position indicated by a barrel on the screen of the monitor 18 based on light detection by a light detection sensor. The acquisition result is passed to the microprocessor 14 at regular intervals (for example, every 1/60 seconds).

  The gun controller 32 is provided with a trigger (trigger). The input / output processing unit 30 scans the state of each unit of the gun controller 32 at regular intervals (for example, every 1/60 seconds), and passes an operation signal representing the scan result to the microprocessor 14 via the bus 12. The microprocessor 14 determines the state of the trigger (whether or not the trigger is pulled) based on the operation signal.

  The game apparatus 10 having the above configuration provides a gun shooting game in which the player virtually shoots the target character displayed on the game screen by the gun controller 32. The game apparatus 10 is based on the position on the game screen (the aim position of the gun controller 32) indicated by the barrel of the gun controller 32 and the display position of the target character on the game screen when the player pulls the trigger. The success or failure of the player's shooting is determined. And a game is advanced according to the determination result.

  In the game apparatus 10, the aiming position of the gun controller 32 is determined when the light of the bright spot moving on the screen of the monitor 18 (light by scanning of the monitor 18) is detected by the light detection sensor of the gun controller 32. It is acquired by acquiring the scanning position. For this reason, in the game apparatus 10, when the barrel of the gun controller 32 is directed to a low-luminance area of the game screen, light detection by the light detection sensor becomes unstable, and the aiming position of the gun controller 32 is preferably acquired. It may not be possible.

  In this regard, the game apparatus 10 is provided with a luminance adjustment parameter, and the game screen is displayed with a luminance corresponding to the value of the luminance adjustment parameter (luminance adjustment value). The value of the brightness adjustment parameter is determined according to the game play environment. For this reason, the brightness of the game screen is suitably adjusted according to the game play environment.

  Further, in the game apparatus 10, the determination of the value of the brightness adjustment parameter as described above is easily performed for the player.

  Furthermore, in the game apparatus 10, changing the luminance of the game screen to the luminance based on the value of the luminance adjustment parameter is realized by a relatively simple process.

  Here, the brightness adjustment screen of the game apparatus 10 will be described in detail. The brightness adjustment screen is a screen for determining the value of the brightness adjustment parameter. 2 to 5 show an example of the brightness adjustment screen displayed on the monitor 18.

  As shown in these drawings, high luminance images 34a and 34b (reference luminance images) are displayed on the left and right sides of the luminance adjustment screen. Circle images 36a and 36b are superimposed on the high luminance images 34a and 34b. The high luminance images 34a and 34b and the circular images 36a and 36b are images having such luminance that the light from the region where these images are displayed is reliably detected by the light detection sensor of the gun controller 32. In the present embodiment, the high luminance images 34a and 34b and the circular images 36a and 36b are white images.

  On the luminance adjustment screen, a plurality of luminance adjustment images 38 having different luminances are displayed in order from the highest luminance between the high luminance images 34a and 34b. The brightness adjustment image 38 is an image formed by translucently combining a high brightness color image with a low brightness color image used for the game image. Each brightness adjustment image 38 is associated with a different brightness adjustment value, and the ratio of the translucent composition is determined based on the brightness adjustment value associated with each brightness adjustment image 38.

  On the brightness adjustment screen, a brightness adjustment image 38 corresponding to each value (brightness adjustment value) that the brightness adjustment parameter can take is displayed. The brightness adjustment parameter in the present embodiment takes a value from 0 to 50. For this reason, the brightness adjustment image 38 corresponding to each of the brightness adjustment values from 0 to 50 is displayed on the brightness adjustment screen of the present embodiment. The brightness adjustment image 38 is an image formed by translucently combining a white image with a black image. The alpha value α of the white image is determined according to a calculation formula of α = (brightness adjustment value / 100) × 255. In other words, in the present embodiment, as the brightness adjustment image 38, a black image is displayed with a brightness corresponding to the brightness adjustment value associated with the brightness adjustment image 38. Further, the brightness adjustment image 38 is configured such that the brightness increases as the associated brightness adjustment value increases.

  The aiming position guide image 40 is displayed on the brightness adjustment screen. The aiming position guide image 40 represents a position on the screen (an aiming position of the gun controller 32) indicated by the barrel of the gun controller 32. When the player changes the direction of the barrel of the gun controller 32, the display position of the aiming position guide image 40 changes accordingly.

  Further, the lower part of the brightness adjustment screen is a message display area 42. In the message display area 42, a message for guiding the player to align the aim position guide image 40 with a predetermined area on the screen or to move horizontally to the predetermined area is displayed. On the brightness adjustment screen, the player changes the direction of the barrel of the gun controller 32 according to the message displayed in the message display area 42, whereby the brightness adjustment parameter value suitable for the game play environment is determined. Yes.

  FIG. 2 shows an initial state of the brightness adjustment screen. On this brightness adjustment screen, a brightness adjustment image corresponding to the brightness adjustment value “50” (the brightness adjustment image with the highest brightness) is displayed. On this brightness adjustment screen, the player changes the direction of the barrel of the gun controller 32 so that the aiming position guide image 40 overlaps the circular image 36a. When it is detected that the aiming position of the gun controller 32 has entered the display area of the circular image 36a, a message for guiding the aiming position guide image 40 to move from the circular image 36a to the circular image 36b as shown in FIG. Is displayed in the message display area 42.

  On the brightness adjustment screen shown in FIG. 3, the player changes the direction of the gun barrel of the gun controller 32 so as to move the aiming position guide image 40 horizontally from the circle image 36a to the circle image 36b. During this time, the game apparatus 10 executes a brightness adjustment information determination process described later (see FIGS. 8 and 9).

  When it is detected that the aiming position of the gun controller 32 has entered the display area of the circular image 36b, the detection result of the light detection unit 46 when the barrel of the gun controller 32 is directed toward the high-intensity images 34a and 34b, The detection result of the light detection unit 46 when directed to the brightness adjustment image 38 is compared, and the brightness adjustment screen is updated as shown in FIGS. 4 and 5, for example, according to the comparison result. The

  The brightness adjustment screen shown in FIG. 4 shows the detection result by the light detection unit 46 when the gun barrel of the gun controller 32 is directed to the high brightness images 34 a and 34 b and the light detection when the gun controller 32 is directed to the brightness adjustment image 38. Displayed when it is determined that the detection result by the unit 46 is equivalent. At this time, the brightness adjustment image 38 having a brightness one level lower than the brightness adjustment image 38 displayed on the brightness adjustment screen shown in FIG. 2 or 3 is displayed on the brightness adjustment screen. For example, when the brightness adjustment image 38 corresponding to the brightness adjustment value “50” is displayed, the brightness adjustment image 38 corresponding to the brightness adjustment value “49” is displayed.

  In the brightness adjustment screen shown in the figure, the player changes the direction of the barrel of the gun controller 32 so as to move the aiming position guide image 40 horizontally from the circular image 36b to the circular image 36a. Also during this period, the brightness adjustment information determination process is executed. Then, the detection result of the light detection unit 46 when the gun barrel of the gun controller 32 is directed to the high luminance images 34a and 34b and the detection result of the light detection unit 46 when it is directed to the luminance adjustment image 38 are shown. If it is determined that they are equivalent, a message for guiding the aiming position guide image 40 to move horizontally from the circle image 36a to the circle image 36b is displayed in the message display area 42. At this time, the brightness adjustment image 38 having a lower brightness is displayed on the brightness adjustment screen.

  The brightness adjustment screen shown in FIG. 5 shows the detection result by the light detection unit 46 when the gun barrel of the gun controller 32 is directed to the high brightness images 34a and 34b, and the light detection when it is directed to the brightness adjustment image 38. This is displayed when it is determined that the detection result by the unit 46 is not equivalent. In this case, a value obtained by adding 1 to the brightness adjustment value associated with the brightness adjustment image 38 is determined as the value of the brightness adjustment parameter.

  Here, functional blocks implemented in the game apparatus 10 will be described. FIG. 6 is a diagram mainly showing those related to the present invention among the functional blocks realized in the game apparatus 10. As shown in the figure, the game apparatus 10 includes a display unit 44, a light detection unit 46, an aim position acquisition unit 47, a game control unit 48 (game image acquisition means), a brightness adjustment information storage unit 50, and a game image display unit 52 ( Game image display means, translucent composition ratio determination means), luminance adjustment image display section 54, and luminance adjustment information determination section 56 (luminance determination means). These functions can be performed by a computer (DVD-ROM or other information storage medium such as a home-use game machine, arcade game machine, portable game machine, mobile phone, portable information terminal, or personal computer). This is realized by executing (provided to the computer by the communication network).

  The display unit 44 mainly includes the monitor 18. The display unit 44 displays the scanning lines by moving the bright spot in the horizontal direction (left and right direction) at high speed, and displays each screen by sequentially shifting the scanning lines in the vertical direction. The display unit 44 displays a game screen, a brightness adjustment screen (FIGS. 2 to 5), and the like.

  The light detection unit 46 mainly includes a known light detection sensor included in the gun controller 32. The light detection unit 46 detects light from the barrel direction of the gun controller 32, particularly light from a screen displayed on the display unit 44. More specifically, the light detection unit 46 detects whether or not scanning is performed on a position (region) indicated by the barrel of the gun controller 32 on the screen of the display unit 44. In other words, it is detected whether or not there is a bright spot at the position (region) where the barrel of the gun controller 32 is directed on the screen of the display unit 44.

  The aim position acquisition unit 47 is mainly composed of a microprocessor. The aim position acquisition unit 47 acquires the aim position of the gun controller 32 based on the detection result by the light detection unit 46. The aiming position acquisition unit 47 acquires the scanning position of the monitor 18 at that time when scanning with respect to the position (region) on the screen corresponding to the barrel direction of the gun controller 32 is detected by the light detection unit 46. The aiming position of the gun controller 32 is acquired. Note that the scanning position of the monitor 18 is, for example, the time required for scanning for one screen on the monitor 18 and the screen data stored in the VRAM of the image processing unit 16 after being supplied to the monitor 18. It may be calculated based on the elapsed time, or may be calculated by another known method. The aiming position acquisition unit 47 may be realized by the gun controller 32 or may be realized by the consumer game machine 11.

  The game control unit 48 is mainly composed of the microprocessor 14. The game control unit 48 controls the game based on the detection result by the light detection unit 46. The game control unit 48 acquires the aiming position of the gun controller 32 calculated by the aiming position obtaining unit 47 every predetermined time. When it is determined that the trigger is pulled based on the operation signal input from the gun controller 32, the game control unit 48 determines the target based on the acquired aim position and the display position of the target character on the game screen. Determine the success or failure of shooting against the character. Based on the determination result, the game control unit 48 reads out the game image (game image data) from the DVD-ROM 25 and supplies it to the game image display unit 52. Alternatively, the game control unit 48 generates a game image based on the determination result and image data read from the DVD-ROM 25 or the like, and supplies the game image to the game image display unit 52.

  The brightness adjustment information storage unit 50 is configured by the main memory 26, a hard disk storage device, and the like. The brightness adjustment information storage unit 50 stores brightness adjustment parameters (brightness adjustment information) as shown in FIG. The brightness adjustment parameter is information indicating how to adjust (change) the brightness of the game screen. The value of the brightness adjustment parameter is referred to by the game image display unit 52. The value of the brightness adjustment parameter is determined by the brightness adjustment information determination unit 56 so as to be suitable for the game play environment. In the present embodiment, the brightness adjustment parameter takes a value from 0 to 50.

  The game image display unit 52 mainly includes the microprocessor 14 and the image processing unit 16. The game image display unit 52 causes the display unit 44 to display the game image (game image data) supplied from the game control unit 48 with luminance based on the value of the luminance adjustment parameter stored in the luminance adjustment information storage unit 50.

  For example, the game image display unit 52 generates a game image (game screen data) whose luminance has been adjusted by semi-transparently combining an image of a predetermined color (predetermined luminance) with the game image. Then, the game image display unit 52 causes the display unit 44 (game screen) to display the game image whose luminance has been adjusted. In this case, the game image display unit 52 determines the ratio of the semi-transparent composition based on the value of the brightness adjustment parameter. For example, the game image display unit 52 stores information indicating the value of the brightness adjustment parameter (or the range of the value of the brightness adjustment parameter) in association with the ratio of the semi-transparent composition, and based on the stored content You may make it determine the ratio of translucent composition.

  In the present embodiment, similarly to the case where the brightness adjustment image 38 is generated, the brightness-adjusted game image is generated by translucently combining the white image with the game image. The alpha value α of the white image is determined according to a calculation formula of α = (value of brightness adjustment parameter / 100) × 255. Thus, in the present embodiment, the game screen is adjusted to be brighter as the value of the brightness adjustment parameter increases.

  Further, for example, the game image display unit 52 may acquire palette data corresponding to the value of the brightness adjustment parameter and display the game image on the display unit 44 based on the palette data. In this case, a plurality of palette data corresponding to each of the values that the brightness adjustment parameter can take may be stored in advance. Alternatively, only reference pallet data (for example, pallet data corresponding to one of the values that the brightness adjustment parameter can take) is stored in advance, and the pallet data corresponding to each value of the brightness adjustment parameter is You may make it produce | generate based on the said reference | standard pallet data.

  In addition, for example, the game image display unit 52 corresponds, in whole or in part, to a palette number and color information belonging to any one of a plurality of palette number groups corresponding to each value that the brightness adjustment parameter can take. Additional pallet data may be stored. In this case, the game control unit 48 may generate a game image in which a palette number belonging to one of a plurality of palette number groups is associated with each pixel constituting the image. Furthermore, the game image display unit 52 may change the palette number associated with each pixel constituting the game image to a palette number belonging to the palette number group corresponding to the value of the brightness adjustment parameter. The game image may be displayed on the display unit 44 based on the palette data.

  Note that the game image display unit 52 may display the game image with luminance based on the value of the luminance adjustment parameter by another known method. Further, it is preferable that the brightness adjusted image and the brightness adjusted game image are generated by the same method. This ensures that the brightness of the game screen can be adjusted to a value suitable for the game play environment.

  The brightness adjustment image display unit 54 mainly includes the microprocessor 14 and the image processing unit 16. The brightness adjustment image display unit 54 causes the display unit 44 to display a plurality of brightness adjustment images having different brightnesses sequentially or simultaneously. For example, the brightness adjustment image display unit 54 may sequentially display the plurality of brightness adjustment images on the display unit 44 in a predetermined brightness order.

  In the present embodiment, the brightness adjustment image display unit 54 causes the display unit 44 to display the above-described brightness adjustment screen (FIGS. 2 to 5). That is, the brightness adjustment image display unit 54 causes the display unit 44 to display a plurality of brightness adjustment images 38 corresponding to each of the values (a plurality of brightness adjustment values) that the brightness adjustment parameter can take in order from the highest brightness.

  The brightness adjustment information determination unit 56 is mainly composed of the microprocessor 14. The brightness adjustment information determination unit 56 determines the brightness of the game screen (game image) displayed on the display unit 44. More specifically, the brightness adjustment information determination unit 56 sets the brightness adjustment parameter based on the brightness of the brightness adjustment image 38 and the detection result of light from the area where the brightness adjustment image 38 is displayed on the brightness adjustment screen. Determine the value. For example, when the detection result of light from the area where the brightness adjustment image 38 is displayed on the brightness adjustment screen satisfies a predetermined condition, the brightness adjustment information determination unit 56 adjusts the brightness based on the brightness of the brightness adjustment image 38. Determine the value of the parameter.

  In addition, the brightness adjustment information determination unit 56 may determine the value of the brightness adjustment parameter based further on the detection result of light from the area where the high brightness images 34a and 34b of the brightness adjustment screen are displayed. For example, the brightness adjustment information determination unit 56 includes a statistic of the aiming position (obtained by the aiming position obtaining unit 47) acquired based on the detection result of light from the area where the high-intensity images 34a and 34b are displayed. The statistics of the aiming position acquired based on the detection result of the light from the area where the brightness adjustment image 38 is displayed may be compared. Then, the value of the brightness adjustment parameter may be determined based on the comparison result.

  When the light detection by the light detection unit 46 becomes unstable (when the frequency of light detection decreases), that is, when the acquisition of the aiming position by the aiming position acquisition unit 47 becomes unstable (when the frequency of acquisition of the aiming position decreases). The distance from the previous aiming position to the current aiming position increases. Therefore, in the present embodiment, the brightness adjustment information determination unit 56 determines whether the gun barrel of the gun controller 32 is directed to the high brightness images 34a and 34b or the brightness adjustment image 38 last time. The average of the distance from the aiming position to the current aiming position is compared, and the value of the brightness adjustment parameter is determined based on the comparison result. Thus, even when the gun controller 32 is directed to the low brightness area, the brightness adjustment is performed so that the aiming position is acquired with the same stability (frequency) as when the gun controller 32 is directed to the high brightness area. The parameter value is determined.

  Here, the brightness adjustment information determination process that is executed centering on the brightness adjustment information determination unit 56 will be described in detail. 8 and 9 are flowcharts showing the brightness adjustment information determination process. In this processing, a message for guiding the aiming position guide image 40 to move from the circular image 36a (or the circular image 36b) to the circular image 36b (or the circular image 36a) is displayed in the message display area 42, and then the circular image 36b. This is executed every predetermined time (1/30 second) until it is detected that the aiming position is included in the area where the circle image 36a is displayed.

  As shown in FIG. 8, in this process, the brightness adjustment information determination unit 56 first determines whether or not the aim position (X, Y) of the gun controller 32 has been acquired by the aim position acquisition unit 47 (S101). For example, when information indicating whether or not the aiming position has been acquired can be acquired from the aiming position acquiring unit 47, the brightness adjustment information determining unit 56 acquires the information and performs the above determination. do it. Further, for example, in the case where information indicating whether or not light (scanning light) emitted by scanning of the monitor 18 (scanning for displaying the brightness adjustment screen) can be detected from the light detection unit 46, the luminance The adjustment information determination unit 56 may acquire the information and make the above determination. Further, for example, when the aiming position acquisition unit 47 continues to hold the aiming position acquired last time until the aiming position is newly acquired, when the aiming position supplied from the aiming position acquisition part 47 is the same as the previous time, The brightness adjustment information determination unit 56 may determine that the aiming position acquisition unit 47 has not acquired the aiming position.

  Here, the description will be made assuming that the aiming position acquisition unit 47 continues to hold the aiming position acquired last time until the aiming position is newly acquired. In this case, the brightness adjustment information determination unit 56 determines whether or not the aiming position supplied from the aiming position acquisition unit 47 is the same as the previous aiming position. Therefore, it is determined that the aiming position is not newly acquired, and the aiming position supplied from the aiming position acquiring unit 47 is ignored. In the following, the “aim position acquired in S101” refers to the aim position supplied from the aim position acquisition unit 47 when it is determined that the aim position acquisition unit 47 has newly acquired the aim position. I mean.

  Next, the luminance adjustment information determination unit 56 acquires the x coordinate (X ′) of the previous aiming position (S102). In the present embodiment, the x-coordinate (X) of the aiming position acquired in S101 is stored in the main memory 26 (see S118). Therefore, the brightness adjustment information determination unit 56 refers to the stored contents of the main memory 26 to obtain the x coordinate (X ′) of the previous aiming position.

  Then, the brightness adjustment information determination unit 56 determines whether both the x coordinate (X) of the current aiming position and the x coordinate (X ′) of the previous aiming position are X1 or more and less than X2 (S103). ). X1 indicates a predetermined x coordinate between the right end of the circular image 36a and the left end of the brightness adjustment image 38, as shown in FIG. X2 indicates the x coordinate of the left end of the brightness adjustment image 38.

  When both X and X 'are greater than or equal to X1 and less than X2, the luminance adjustment information determination unit 56 calculates a distance (W1) between X and X' (S104). W1 indicates the distance between X and X 'when the barrel of the gun controller 32 is directed to the high-intensity image 34a. The brightness adjustment information determination unit 56 stores the value of W1 in the main memory 26 (S105). As shown in FIG. 10, the main memory 26 stores a history of W1 values calculated in this step.

  If at least one of X and X 'is not equal to or greater than X1 and less than X2, the luminance adjustment information determination unit 56 determines whether both X and X' are equal to or greater than X2 and less than X3 (S106). X3 represents the x coordinate of the right end of the brightness adjustment image 38.

  When both X and X 'are greater than or equal to X2 and less than X3, the luminance adjustment information determination unit 56 calculates a distance (W2) between X and X' (S107). W2 indicates the distance between X and X ′ when the barrel of the gun controller 32 is directed toward the brightness adjustment image 38. The brightness adjustment information determination unit 56 stores the value of W2 in the main memory 26 (S108). As shown in FIG. 10, the main memory 26 stores a history of W2 values calculated in this step.

  If at least one of X and X ′ is not X2 or more and less than X3, the luminance adjustment information determination unit 56 determines whether both X and X ′ are X3 or more and less than X4 (S109). Note that X4 indicates a predetermined x coordinate between the right end of the brightness adjustment image 38 and the left end of the circular image 36b, as shown in FIG.

  When both X and X 'are greater than or equal to X3 and less than X4, the luminance adjustment information determination unit 56 calculates a distance (W3) between X and X' (S110). W3 indicates the distance between X and X 'when the barrel of the gun controller 32 is directed to the high-intensity image 34b. The brightness adjustment information determination unit 56 stores the value of W3 in the main memory 26 (S111). As shown in FIG. 10, the main memory 26 stores a history of W3 values calculated in this step.

  Next, it is determined whether or not the aiming position of the brightness adjustment information determination unit 56 gun controller 32 is within the target circle (S112). This determination is made based on the aiming position and the display position of the target circular image 36b (or the circular image 36a).

  If the aiming position is not within the target circle, the brightness adjustment information determining unit 56 stores the x-coordinate (X) of the aiming position in the main memory 26 (S118). Then, the brightness adjustment image display unit 54 updates the brightness adjustment screen so that the display position of the aiming position guide image 40 becomes the aiming position acquired in S101 (S119).

  On the other hand, when the aiming position is within the target circle, the brightness adjustment information determination unit 56 calculates the average value (WA1, WA2, WA3) of W1, W2, and W3 (S113). WA1 indicates an average value of W1 acquired while the aiming position moves from the circular image 36a (or the circular image 36b) to the circular image 36b (or the circular image 36a). Similarly, WA2 and WA3 indicate average values of W2 and W3 acquired while the aiming position moves from the circular image 36a (or the circular image 36b) to the circular image 36b (or the circular image 36a), respectively. This average value is calculated based on the history of W1, W2, and W3 (FIG. 10) stored in the main memory 26. After this calculation is performed, the history of W1, W2, and W3 stored in the main memory 26 is deleted.

  Next, the brightness adjustment information determination unit 56 determines whether or not the difference between W2 and (WA1 + WA3) / 2 is within a threshold (S114). That is, the brightness adjustment information determination unit 56 detects the light detection unit 46 when the gun controller 32 is directed to the brightness adjustment image 38, as in the case where the gun controller 32 is directed to the high brightness images 34a and 34b. It is determined from the above difference whether or not the detection is performed.

  When the difference is within the threshold value, the brightness adjustment information determination unit 56 is equivalent to the case where the gun controller 32 is directed to the brightness adjustment image 38, even when the gun controller 32 is directed to the brightness adjustment image 34a. It is determined that light detection (acquisition of aiming position) by the light detection unit 46 can be performed at a frequency.

  In this case, the brightness adjustment image display unit 54 updates the brightness adjustment screen as shown in FIG. 4 (S115). That is, the brightness adjustment image display unit 54 updates the brightness adjustment image 38 to one corresponding to a brightness adjustment value that is one smaller than the brightness adjustment value corresponding to the currently displayed one. For example, when the brightness adjustment image 38 corresponding to the brightness adjustment value “50” is displayed, the brightness adjustment image display unit 54 updates this to the one corresponding to the brightness adjustment value “49”. Further, the brightness adjustment image display unit 54 updates the display position of the aim position guide image 40 to the aim position acquired in S101. Further, the brightness adjustment image display unit 54 displays a message for guiding the aiming position guide image 40 to move from the circular image 36b (or the circular image 36a) to the circular image 36a (or the circular image 36b) in the message display area 42. . At this time, the brightness adjustment image display unit 54 may blink the next target circular image 36a (or the circular image 36b).

  On this brightness adjustment screen, the player changes the direction of the gun controller 32 in order to move the aiming position guide image 40 from the circular image 36b to the circular image 36a. Even in this case, whether or not the light detection unit 46 detects the brightness adjusted image 38 with the brightness lowered by one level is performed with the same frequency as the high brightness images 34a and 34b. Is done.

  On the other hand, when the difference is larger than the threshold (S114), the brightness adjustment information determination unit 56 is directed to the high brightness images 34a and 34b when the gun controller 32 is directed to the brightness adjustment image 38. It is determined that the light detection (acquisition of aiming position) by the light detection unit 46 could not be performed with the same frequency.

  In this case, the luminance adjustment information determination unit 56 determines a value obtained by adding 1 to the luminance adjustment value associated with the currently displayed luminance adjustment image 38 as the value of the reference adjustment parameter (S116). Then, the brightness adjustment image display unit 54 updates the brightness adjustment screen as shown in FIG. 5, for example (S117). That is, the brightness adjustment image display unit 54 updates the display position of the aim position guide image 40 to the aim position acquired in S101, and displays a message in the message display area 42 for guiding the player that the brightness adjustment has been completed. Let

  The above processing is realized by the game apparatus 10 executing a program supplied to the computer via a computer-readable information storage medium such as a DVD-ROM or a communication network.

  Next, a game screen display process that is executed centering on the game control unit 48 and the game image display unit 52 will be described. FIG. 11 is a flowchart showing game screen display processing. This process is executed every predetermined time (for example, 1/30 second).

  As shown in the figure, in this process, first, the game control unit 48 acquires a game image (game image data) and draws it in the VRAM of the image processing unit 16 (S201). For example, the game control unit 48 draws the game image read from the DVD-ROM 25 or the like on the VRAM. Further, for example, the game control unit 48 generates a game image based on the image data read from the DVD-ROM 25 or the like and draws it in the VRAM.

  For example, when the gun shooting game provided by the game apparatus 10 is for shooting a target character placed in a virtual three-dimensional game space, the three-dimensional game space is given a given viewpoint as follows. An image (view image) representing a state viewed from the above is generated. And the game image produced | generated based on the visual field image is drawn on VRAM.

  That is, first, environmental processing is executed. In the environment processing, the positions and orientations of all static objects and dynamic objects in the three-dimensional game space are calculated. A static object is an object that does not change the position of a building or the like. On the other hand, a dynamic object is an object that changes its position and posture like a target character.

  In the environment processing, the viewpoint coordinates, the line-of-sight direction, and the angle of view are also calculated. For example, in the standard state, the viewpoint coordinates are set above the player character (the character that is the operation target of the player). Further, the line-of-sight direction is set so as to face the front of the player character. Thus, the viewpoint follows the player character. For the angle of view, for example, a fixed value is used. The virtual camera is virtually arranged in the three-dimensional game space according to the viewpoint coordinates, the line-of-sight direction, and the angle of view calculated in this way.

  Thereafter, geometry processing is executed. In geometry processing, coordinates from the world coordinate system (XW, YW, ZW) to the viewpoint coordinate system, that is, the coordinate system with the viewpoint coordinate as the origin, the gaze direction as the Z direction, the horizontal direction as the X direction, and the vertical direction as the Y direction. Perform conversion. In addition, for the polygons constituting each object, vertex color information is calculated based on light source information (light source color and position). In addition, clipping processing is also performed.

  Thereafter, a rendering process is executed. That is, the vertex coordinates, vertex color information, texture coordinates, and the like of each polygon in the field of view are passed to the image processing unit 16. Then, the image processing unit 16 forms a game image including a visual field image on the VRAM based on the information. The visual field image is formed by converting each object described in the viewpoint coordinate system into the screen coordinate system.

  Next, the game image display unit 52 reads the value of the brightness adjustment parameter stored in the brightness adjustment information storage unit 50 (S202). Then, the game image display unit 52 calculates an alpha value of a white image to be translucently synthesized with the game image (S203). The alpha value α of the white image is calculated according to α = (value of brightness adjustment parameter / 100) × 255.

  Then, the game image display unit 52 causes the white image to be translucently synthesized with the alpha value calculated in S203 to the game image formed on the VRAM in S201 (S204). In this way, a brightness-adjusted game image (game screen) is formed on the VRAM in accordance with the game play environment. The image formed in the VRAM is output to the display unit 44 at a predetermined timing.

  The above processing is realized by the game apparatus 10 executing a program supplied to the computer via a computer-readable information storage medium such as a DVD-ROM or a communication network.

  As described above, in the game apparatus 10, the brightness adjustment image corresponding to each of the possible values of the brightness adjustment parameter is displayed on the brightness adjustment screen. The value of the brightness adjustment parameter is determined based on the detection result of the light detection unit 46 when the gun controller 32 is directed to each brightness adjustment image. Therefore, the value of the brightness adjustment parameter is determined so that the brightness of the game screen is suitable for the game play environment. For this reason, according to the game device 10, even when the gun barrel of the gun controller 32 is directed to the portion having the lowest luminance on the game screen in the game play environment, the light detection by the light detection unit 46 is preferably performed. As a result, the brightness of the game screen can be suitably adjusted so that the aiming position of the gun controller 32 is preferably obtained.

  In the game apparatus 10, when determining the value of the brightness adjustment parameter, the player changes the barrel direction of the gun controller 32 from the circle image 36a to the circle image 36b or from the circle image 36b to the circle image according to a message displayed on the screen. It is only necessary to repeat the change to 36a. For this reason, according to the game device 10, the player can adjust the brightness of the game screen without difficulty.

  In the game apparatus 10, the brightness adjustment image 38 is sequentially displayed on the brightness adjustment screen from the highest brightness to the lowest brightness. For this reason, according to the game device 10, the value of the brightness adjustment parameter suitable for the game play environment can be calculated with high accuracy.

  Furthermore, the game apparatus 10 changes the luminance of the game screen by semi-transparently combining a white image with the alpha value based on the value of the luminance adjustment parameter with respect to the game image. For this reason, according to the game apparatus 10, the brightness of the game screen can be changed in software by a relatively simple process.

  The present invention is not limited to the embodiment described above.

  For example, in the above description, when the player changes the orientation of the gun controller 32 according to the message displayed on the brightness adjustment screen, the brightness adjustment parameter value (the brightness of the game screen) is determined by the brightness adjustment information determination unit 56. However, the player may be able to specify the value of the brightness adjustment parameter. That is, the game apparatus 10 (luminance determination means) may receive an input of the value of the brightness adjustment parameter from the player and determine the value as the value of the brightness adjustment parameter.

  Further, for example, the example in which the present invention is applied to the gun shooting game apparatus has been described above, but the present invention is not limited to the gun shooting game apparatus but can be applied to other game apparatuses.

  In the above description, the program is supplied from the DVD-ROM 25, which is an information storage medium, to the consumer game machine 11. However, the program may be distributed to a home or the like via a communication network. FIG. 12 is a diagram showing an overall configuration of a program distribution system using a communication network. A program distribution method according to the present invention will be described with reference to FIG. As shown in the figure, the program distribution system 100 includes a game database 102, a server 104, a communication network 106, a personal computer 108, a consumer game machine 110, and a PDA (personal digital assistant) 112. Among these, the game database 102 and the server 104 constitute a program distribution device 114. The communication network 106 includes, for example, the Internet and a cable television network. In this system, a game database (information storage medium) 102 stores a program similar to the content stored in the DVD-ROM 25. Then, when a consumer makes a game distribution request using the personal computer 108, the home game machine 110, the PDA 112, or the like, it is transmitted to the server 104 via the communication network 106. Then, the server 104 reads the program from the game database 102 in response to the game distribution request, and transmits it to the game distribution request source such as the personal computer 108, the home game machine 110, the PDA 112, and the like. Here, the game is distributed in response to the game distribution request, but the server 104 may transmit the game unilaterally. Further, it is not always necessary to distribute (collectively distribute) all programs necessary for realizing the game at a time, and a necessary portion may be distributed (divided distribution) according to the situation of the game. If the game is distributed via the communication network 106 in this way, the consumer can easily obtain the program.
