Description

  The present invention relates to a game device, an operation evaluation method, and a program capable of appropriately evaluating a player's operation even when a predetermined display delay occurs on the display device side.

Conventionally, various games (software or the like) that are executed on a business or home game device have been developed. Among them, games collectively called music games (including dance games and the like) are very popular and are supported by players of a wide range of ages.
This music game is a type of game in which a player competes for a high score by performing an operation that matches the rhythm or musical scale of a musical piece to be played with good timing.

To give a specific example, the timing at which predetermined objects appear sequentially from the top of the screen and move downwards in synchronization with the music being played, and when these objects reach the reference judgment line Thus, when the player presses a button on the controller, a score is obtained.
Note that the buttons to be pressed are determined according to the type of object and the moving lane (musical scale, etc.), and if the buttons to be pressed are different even if the timings coincide, no score is obtained. That is, the player is required to perform a correct button operation rhythmically while observing the object that moves with the music performance.

As an example of such a music game, a technique of a music game system capable of increasing the interest of the player by devising an operation guidance method is also disclosed (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 2001-145777 (pages 7-14, FIG. 10)

In recent years, display devices such as liquid crystal displays and plasma displays (such as thin televisions) have become widespread. Further, an increasing number of players enjoy playing games by connecting home game devices to such display devices.
In this type of display device, the screen is further enlarged, and a predetermined display delay (for example, a delay of several tens to several hundreds of milliseconds) occurs before the video based on the input video signal is displayed on the screen. ing. Note that if the display device immediately outputs audio from the input audio signal, it will deviate from the displayed video (because the audio comes first and video later), so the audio will be synchronized with the display delay on the video side. The video side and the audio are also synchronized by delaying the internal side accordingly.

In the music game described above, the relationship between the operation of the player and the position of the object being displayed (whether or not it is on the determination line, etc.) is a particularly important factor, and such a display delay occurs in the display device. Then, the position of the object recognized on the game device side is shifted from the position of the object actually displayed, and the player's operation cannot be evaluated appropriately.
Therefore, in the conventional music game, in order to cope with such a display delay, for example, on the setting screen (environment setting etc.) during the game, the general type of display device to be used (CRT / liquid crystal / plasma etc.) The player can select the screen size (large / small, etc.).
Then, the operation timing of the player is evaluated by delaying the comparison timing on the reference data side as a reference by a delay time corresponding to the selected type. In other words, the effect of the display delay has been attempted to be eliminated by delaying the comparison timing with the prescribed data that defines the operation content imposed on the player by the set delay time.

However, since the display delay of the display device is originally different depending on the manufacturer, product, etc., it is extremely rare that the delay time set by rough typing matches the actual display delay. In addition, if the player makes a mistake in selecting a type or the like, the difference between the set delay time and the actual display delay time may be further increased.
Furthermore, when the game device is connected to the display device via a digital recorder (such as a hard disk recorder), the delay on the digital recorder side is also added to the display delay, so it can be set. Even with the longest delay time, it was impossible to fill the difference from the actual display delay time.

  Therefore, there has been a demand for a technique for eliminating the influence of display delay in accordance with an actual display device (connected to the game device) used by the player (environment to the display device or the like).

  The present invention has been made to solve such a problem, and a game apparatus and an operation evaluation capable of appropriately evaluating a player's operation even when a predetermined display delay occurs on the display apparatus side. It is an object to provide a method and a program.

  A game apparatus according to a first aspect of the present invention is a game apparatus that supplies a video signal and an audio signal to an external display device that synchronizes video display and audio output, and includes a display delay calculation unit, an image A generation unit, an operation information acquisition unit, a timing adjustment unit, and an evaluation unit are included.

Further, the image generation unit generates a display image including an image for guiding the target operation to the player based on the prescribed operation information that defines the operation content of the controller imposed on the player. The operation information acquisition unit acquires operation information of the controller operated by the player during the game. The timing adjustment unit adjusts the comparison timing of the prescribed operation information with respect to the acquired operation information based on the calculated display delay time. Then, the evaluation unit evaluates the player's operation based on the relationship between the operation information and the prescribed operation information at the adjusted comparison timing.

That is, before the game starts, the display delay calculation unit appropriately calculates the display delay generated in the display device. Then, during the game, the timing adjustment unit delays the prescribed operation information in time series based on the calculated display delay. Thereby, since the influence of the display delay is eliminated, the evaluation unit can appropriately evaluate the operation of the player based on the relationship between the operation information of the player and the specified operation information.
As a result, even when a predetermined display delay occurs on the display device side, the player's operation can be appropriately evaluated.

The controller has a predetermined speaker, and the game device further includes an auxiliary audio supply unit that supplies the same audio signal as the audio signal supplied to the display device to the controller, and the auxiliary audio supply unit Changes the supply timing of the audio signal supplied to the controller in accordance with the operation of the player, and the display delay calculation unit is in a state where the audio output from the display device and the audio output from the controller are synchronized The display delay time may be calculated based on the amount of change in the supply timing.
In this case, for example, the player adjusts the supply timing of the sound to the controller so that the sound from the display device (speaker) and the sound from the controller's speaker are output simultaneously (so as to be heard as one sound). By doing so, the display delay time is calculated.

The controller includes a predetermined microphone, and the game apparatus further includes an auxiliary sound acquisition unit that acquires sound obtained by collecting sound output from the display device with the microphone from the controller. The display delay calculation unit may calculate the display delay time based on a delay time from when the audio signal is supplied to the display device until the auxiliary audio acquisition unit acquires the audio.
In this case, the delay of the audio signal collected by the controller with respect to the audio signal supplied to the display device can be obtained, and this delay time can be automatically calculated as the display delay time.

The controller has a predetermined image sensor (for example, a CCD or a CMOS), and a display image acquisition unit that acquires image information obtained by capturing an image displayed on the display device with the image sensor from the controller. The display delay calculation unit calculates the display delay time based on a delay time from when the video signal is supplied to the display device until the display image acquisition unit acquires the image. Also good.
In this case, the delay of the display image taken by the controller with respect to the video signal supplied to the display device can be obtained, and this delay time can be automatically calculated as the display delay time.

The game apparatus further includes a music playback unit that plays back music sound from music information, and a specified operation information generation unit that generates the specified operation information based on the music information, wherein the image generation unit In synchronization with the music sound to be generated, a display image including an object moving in a predetermined direction is generated, and the operation information acquisition unit moves the object to a predetermined position (for example, a determination line) in the display image At this time, operation information of the controller that can be operated by the player may be acquired.
In this case, the player's operation in the music game can be appropriately evaluated.

  An operation evaluation method according to a second aspect of the present invention is an operation evaluation method in a game device that supplies a video signal and an audio signal to an external display device that synchronizes video display and audio output. It includes a delay calculation step, an image generation step, an operation information acquisition step, a timing adjustment step, and an evaluation step.

  First, in the display delay calculation step, for example, before the game starts, the display delay time from the supply of the video signal to the display of the video on the display device is obtained from the controller (for example, the operation in the controller It is calculated based on information (adjustment information), information collected by the controller or photographed). In the image generation step, a display image including an image for guiding the target operation to the player is generated based on the prescribed operation information that defines the operation content of the controller imposed on the player. In the operation information acquisition step, operation information of the controller operated by the player during the game is acquired. In the timing adjustment step, the comparison timing of the specified operation information with respect to the acquired operation information is adjusted based on the calculated display delay time. In the evaluation step, the player's operation is evaluated based on the relationship between the operation information and the specified operation information at the adjusted comparison timing.

That is, before the game starts, the display delay occurring in the display device is appropriately calculated in the display delay calculation step. Then, during the game, in the timing adjustment step, the prescribed operation information is delayed in time series based on the calculated display delay. Thereby, since the influence of the display delay is eliminated, the player's operation can be appropriately evaluated based on the relationship between the player's operation information and the prescribed operation information in the evaluation step.
As a result, even when a predetermined display delay occurs on the display device side, the player's operation can be appropriately evaluated.

  A program according to a third aspect of the present invention is configured to cause a computer (including an electronic device) to function as the above game device.

  This program can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, the player's operation can be appropriately evaluated even when a predetermined display delay occurs on the display device side.

Further, the display 290 internally delays the audio output based on the input audio signal in accordance with the display delay, and maintains the synchronization between the video display and the audio output.

(Outline configuration of game device)
FIG. 3 is a schematic diagram showing a schematic configuration of the game device according to the present embodiment. As an example, this game apparatus is an apparatus that evaluates a player's operation according to a screen display or the like.
More specifically, while displaying predetermined music information and displaying an image for guiding (promoting) the player's operation on the display 290, the operation information is acquired from the controller 210, and the operation content of the player is displayed. It is a device that implements music games such as evaluation. Hereinafter, a description will be given with reference to FIG.

  The game apparatus 300 includes a wireless communication unit 310, an operation information acquisition unit 320, an auxiliary audio supply unit 330, a music information storage unit 340, an image information storage unit 350, a processing control unit 360, and a music playback unit 370. And an image generation unit 380.

First, the wireless communication unit 310 sequentially performs wireless communication with the controller 210 to transmit / receive necessary information.
For example, the wireless communication unit 310 receives information sent from the controller 210 and supplies this information to the operation information acquisition unit 320. In addition, the wireless communication unit 310 transmits the sound information (a sound signal for sound matching described later) supplied from the auxiliary sound supply unit 330 to the controller 210.
The controller unit 105 can function as such a wireless communication unit 310.

The operation information acquisition unit 320 acquires operation information via the wireless communication unit 310 and acquires the operation content of the controller 210 by the player. That is, it is obtained in real time which button of the controller 210 the player has pressed.
Note that the operation information acquisition unit 320 provides operation information for sound matching, which will be described later, to the processing control unit 360 (display delay calculation unit 361, which will be described later in detail) before playing the music game (at the time of initial setting or the like). To supply. Further, while playing the music game, the operation information acquisition unit 320 supplies the operation information of the player to the processing control unit 360 (more specifically, an evaluation unit 364 described later).
The interface 104 or the like can function as such an operation information acquisition unit 320.

The auxiliary sound supply unit 330 supplies sound signals for sound matching to the controller 210 via the wireless communication unit 310 for sound matching before play. This sound matching is to synchronize the sound output from the display 290 and the sound output from the controller 210. For this purpose, the auxiliary sound supply unit 330 responds to the operation of the player by the controller 210. It is possible to appropriately change the timing for supplying the audio signal to the.
The interface 104 or the like can function as such an auxiliary audio supply unit 330.

The music information storage unit 340 stores a plurality of pieces of music information to be reproduced as accompaniment when playing a music game. For example, music information in a predetermined format such as MIDI (Musical Instrument Digital Interface) data is stored. The player can select a favorite song and play a music game in accordance with the song sound.
The music information storage unit 340 also stores music information for use in sound matching. For example, music information such as a metronome sound that repeatedly and sharply repeats at regular intervals is stored.
Note that the DVD-ROM and the RAM 103 attached to the DVD-ROM drive 107 can function as such a music information storage unit 340.

The image information storage unit 350 stores various image information. For example, a background image to be displayed during the play of a music game, image information such as an object to be moved in synchronization with the rhythm of the music to be reproduced, and the like are stored.
Note that the DVD-ROM mounted on the DVD-ROM drive 107 and the RAM 103 can function as such an image information storage unit 350.

  The process control unit 360 controls the entire game device 300. For example, the processing control unit 360 includes a display delay calculation unit 361, a specified operation information generation unit 362, a timing adjustment unit 363, and an evaluation unit 364.

The display delay calculation unit 361 calculates a display delay time from when the video signal is supplied to the display 290 to when the video is displayed based on information obtained from the controller 210.
Specifically, the display delay calculation unit 361 supplies (reproduces) the audio signal of the above-described music for music matching to the auxiliary audio supply unit 330 and the music reproduction unit 370, and from the speaker of the controller 210 and the speaker of the display 290. Output each. At this time, if audio signals are simultaneously supplied to the controller 210 and the display 290, as shown in FIG. 4A, the audio output from the display 290 is output from the controller 210 for a time corresponding to the display delay (delay d). This is later than the audio output (as described above, the display 290 maintains the synchronization between the video display and the audio output).
In this state, the player operates a predetermined button of the controller 210 to appropriately delay the supply timing of the audio signal to the auxiliary audio supply unit 330. As shown in FIG. The output is synchronized with the audio output from the display 290. That is, sound matching is performed so that each sound is output simultaneously (so that it can be heard as one sound).

  The display delay calculation unit 361 calculates the display delay time based on the amount of change in the supply timing (the time during which the supply of the audio signal to the controller 210 is delayed) in the sound matching state shown in FIG. . For example, the display delay calculation unit 361 calculates the delay time of the final supply timing according to the operation from the player as the display delay time of the display 290.

The prescribed operation information generation unit 362 generates prescribed operation information that defines the operation contents of the controller imposed (required) on the player in accordance with the music to be played. For example, the prescribed operation information generation unit 362 generates prescribed operation information that defines, in time series, the buttons of the controller 210 to be pressed by the player and the pressing timing thereof from the rhythm (tempo) of the music information, the scale of the melody, and the like. .
Specifically, as shown in FIG. 5A, the prescribed operation information generation unit 362 generates prescribed operation information that defines the pressing timing that matches the rhythm of the music information. 5A shows an example in which only the pressing timing of one button corresponding to one musical scale or the like is defined for easy understanding of the description. Assume that the pressing timings for a plurality of buttons are respectively defined corresponding to the scale and the like.
The prescribed operation information is used when the image generation unit 380 generates a display image, and the operation content of the player is evaluated by the evaluation unit 364 (after the comparison timing is adjusted by the timing adjustment unit 363). Also used to do.

The timing adjustment unit 363 adjusts the comparison timing of the specified operation information generated by the specified operation information generation unit 362 based on the display delay time calculated by the display delay calculation unit 361. For example, the time series of the prescribed operation information is delayed by a time corresponding to the display delay.
Specifically, as shown in FIG. 5B, the timing adjustment unit 363 delays the original time series of the prescribed operation information based on the display delay time (delay d). FIG. 5B also shows an example in which only the pressing timing of one button is specified, but actually, the pressing timing for a plurality of buttons is specified corresponding to other scales and musical instruments. It shall be.

The evaluation unit 364 evaluates the player's operation based on the relationship between the operation information and the prescribed operation information at the comparison timing adjusted by the timing adjustment unit 363. That is, the operation content of the player is evaluated by comparing the prescribed operation information delayed in time series by the time corresponding to the display delay with the operation information acquired from the operation information acquisition unit 320.
Specifically, as shown in FIG. 5C, the evaluation unit 364 compares the prescribed operation information adjusted in timing with the operation information of the player (press information of the corresponding button) in time series, and performs the player's operation. evaluate. FIG. 5C also shows the pressing timing of one specified button and the pressing timing of one (same) button that is actually operated. Each will be evaluated.
The CPU 101 can function as the processing control unit 360 having such a configuration.

Returning to FIG. 3, the music playback unit 370 is controlled by the processing control unit 360 to perform playback of music.
For example, the music playback unit 370 plays music based on the music information while playing a music game, supplies a sound signal accompanying the playback to the display 290, and outputs the music sound from the speaker of the display 290.
In addition, when performing sound matching before play, the music reproducing unit 370 reproduces music for sound matching and supplies an audio signal to the display 290.
Note that the audio processing unit 109 can function as such a music playback unit 370.

The image generation unit 380 is controlled by the processing control unit 360 and generates a display image (game screen) or the like when playing a music game.
For example, the image generation unit 380 generates a display image including an image for guiding the player's operation, and supplies the display image as a video signal to the display 290 for display on the screen.

Specifically, the image generation unit 380 generates a display image as shown in FIG. In FIG. 6A, each object OBJ appears sequentially from above along lanes (lanes La1 to La3) corresponding to musical scales, musical instruments, etc., in synchronization with the rhythm of the music to be played back, respectively. It shows how it moves to disappear.
Note that the appearance timing and movement speed of each object OBJ are calculated based on the prescribed operation information generated by the prescribed operation information generation unit 362. That is, each object OBJ is controlled such that each object OBJ reaches the determination line LN at each timing determined by the player to be operated by the prescribed operation information. This allows the player to correspond to the buttons (lanes La1 to La3) of the controller 210 at the timing when the object OBJ reaches the determination line LN (more preferably, the timing when the horizontal line of the object OBJ overlaps the determination line LN). Button). When the correct button is pressed by the player, the score is added.
By the way, the shape of the object OBJ shown in FIG. 6A is an example, and may be another shape. For example, the image generation unit 380 may generate a display image for moving the object OBJ as shown in FIGS.
Further, the moving direction of the object OBJ is not limited to the upper side to the lower side (vertical direction) as shown in FIG.

FIG. 7 is a flowchart showing the flow of display delay calculation processing executed before playing the music game in the game device 300 having the above-described configuration. FIG. 8 is a flowchart showing the flow of the operation evaluation process executed during the music game play. Hereinafter, the operation of the game apparatus 300 will be described with reference to these drawings.
First, the display delay calculation process will be described with reference to FIG. This display delay calculation process is started, for example, when the display delay calculation is instructed by the player from the initial setting screen.

When the display delay calculation process is started, the game apparatus 300 sequentially generates sound signals of music for sound matching and supplies them to the controller 210 and the display 290, respectively (step S301). For example, an audio signal of a music such as a metronome sound that repeatedly emits a short (sharp) sound at regular intervals is supplied (reproduced) to the auxiliary audio supply unit 330 and the music reproduction unit 370, and the speaker of the controller 210 and the display 290 Output from each speaker.
In the initial state, sound signals for sound matching are simultaneously supplied to the controller 210 and the display 290, respectively, and as shown in FIG. 4A, the sound from the display 290 is output for the time corresponding to the display delay. Is output later than the sound from the controller 210.

  The game device 300 determines whether or not an adjustment instruction has been given by the player's operation (step S302). That is, in a state where the sound from the display 290 and the sound from the controller 210 are shifted, the player operates a predetermined button on the controller 210 to instruct the timing adjustment on the controller 210 side in order to perform sound matching. Therefore, the game apparatus 300 determines whether or not such an adjustment instruction has been accepted.

If it is determined that there is no adjustment instruction from the player (step S302; No), the game device 300 advances the process to step S305 described later.
On the other hand, when it is determined that there is an adjustment instruction (step S302; Yes), the game apparatus 300 adjusts the supply timing of the audio signal to the controller 210 according to the received adjustment instruction (step S304).
For example, when the “+ button” (one button among the various buttons 215) of the controller 210 is pressed and an adjustment instruction for delaying the supply timing is issued, the game apparatus 300 receives a certain time (as an example) from the current supply timing. The audio signal is supplied to the controller 210 with a delay of 10 milliseconds).

  Game device 300 determines whether or not the sound matching is completed (step S305). That is, by the player's operation, as shown in FIG. 4B described above, the sound output from the controller 210 can be synchronized with the sound output from the display 290, and the sound matching completion operation (for example, It is determined whether or not (A button 213 has been pressed).

If it is determined that the sound matching is not completed (step S305; No), the game device 300 returns the process to step S302 described above.
On the other hand, when it is determined that the sound matching has been completed (step S305; Yes), the game device 300 obtains a supply timing delay time and calculates it as a display delay time (step S306). That is, the display delay calculation unit 361 calculates the delay time of the final supply timing according to the operation from the player as the display delay time of the display 290.
The display delay time calculated in this way is stored in a non-volatile memory (for example, the external memory 106) and can be read at any time, and a new display delay is calculated while the connected display 290 is not changed. The processing may be omitted.

  Next, the operation evaluation process will be described with reference to FIG. This operation evaluation process is started in a state where the display delay time of the display 290 is calculated by the display delay calculation process described above.

  First, when a music piece to be an accompaniment is selected by the player, the game device 300 generates prescribed operation information from the music information (step S401). That is, the prescribed operation information generation unit 362 generates prescribed operation information that defines the buttons of the controller 210 to be pressed by the player and the pressing timing thereof in time series from the rhythm of the music information, the scale of the melody, and the like.

  The game device 300 adjusts the comparison timing of the prescribed operation information based on the calculated display delay time (step S402). That is, the timing adjustment unit 363 delays the time series of the prescribed operation information by a time corresponding to the display delay calculated by the display delay calculation unit 361.

  The game apparatus 300 starts playing the music sound and starts generating a display image (step S403). That is, the music reproducing unit 370 reproduces music sound based on the selected music information, supplies an audio signal accompanying the reproduction to the display 290, and outputs the music sound from the speaker of the display 290. Further, the image generation unit 380 generates a display image as shown in FIG. 6A described above, supplies this video signal to the display 290, and causes the display 290 to display it.

As described above, when the music sound is reproduced on the game apparatus 300 side, the display image is generated, and the audio signal and the video signal are supplied to the display 290, the music sound is output from the speaker of the display 290 with a predetermined display delay. In addition, a display image as shown in FIG. 6A is displayed.
Then, the player follows the movement of the object OBJ in synchronization with the rhythm of the music as shown in FIG. 6A, and at the timing when the object OBJ reaches the determination line LN, the corresponding operation button. The controller 210 is operated to press the button. For this reason, the game apparatus 300 sequentially acquires operation information of the controller 210.

The game apparatus 300 sequentially compares the prescribed operation information whose timing has been adjusted and the operation information of the player (step S404). That is, the evaluation unit 364 compares the prescribed operation information delayed in time series by the time corresponding to the display delay with the operation information acquired from the controller 210 via the operation information acquisition unit 320, and the operation content of the player To evaluate.
Specifically, as shown in FIG. 5C described above, the prescribed operation information with adjusted timing and the player's operation information (the corresponding button press information) are compared in time series to evaluate the player's operation. To do.

  Then, only when it is determined that the operation information of the player matches the specified operation information (step S405; Yes), the game apparatus 300 adds a score and displays an announcement image for notifying that an effective operation has been performed. The display image is synthesized (step S406). For example, as shown in FIG. 9, when the object OBJ in the lane La1 reaches the determination line LN and the button of the controller 210 corresponding to the lane La1 is pressed, the evaluation unit determines that the player's operation is valid. It is evaluated at 364, and the announcement image AN is synthesized and displayed.

The game device 300 determines whether or not the game is over (step S407). That is, it is determined whether or not the music game for one time (one music) is finished.
If it is determined that the game has not ended (step S407; No), the game device 300 returns the process to step S404 described above. And the process of step S404-S407 is repeatedly performed.
On the other hand, when it is determined that the game has ended (step S407; Yes), the game apparatus 300 displays a predetermined end message, a total score, and the like, and then ends the operation evaluation process.

  By such display delay calculation processing and operation evaluation processing, it is possible to eliminate the influence of display delay generated according to the display 290 used by the player, and to appropriately evaluate the player's operation. That is, in the display delay calculation process, first, the display delay occurring in the display 290 is appropriately calculated. In the operation evaluation process, the prescribed operation information is delayed in time series based on the calculated display delay. Thereby, when the operation information of the player is compared with the prescribed operation information, since the influence of the display delay has already been eliminated, the operation of the player can be evaluated appropriately.

  As a result, even when a predetermined display delay occurs on the display device side, the player's operation can be appropriately evaluated.

(Embodiment 2)
In the above embodiment, the player manually synchronizes the sound output from the controller 210 and the sound output from the display 290, and the display delay time is calculated from the delay time of the supply timing to the controller 210 in that state. The case of calculation was explained.
However, the method for calculating the display delay time is not limited to this, and can be changed as appropriate. For example, the display delay time may be calculated by collecting the sound output from the display 290 and automatically obtaining the delay from the time of supply.

FIG. 10 is a schematic diagram showing a schematic configuration of a game apparatus according to the second embodiment of the present invention, which collects sound and calculates display delay time.
The game apparatus 400 includes a wireless communication unit 310, an operation information acquisition unit 320, a microphone sound acquisition unit 410, a music information storage unit 340, an image information storage unit 350, a processing control unit 360, and a music playback unit 370. And an image generation unit 380.
The configuration other than the microphone sound acquisition unit 410 is substantially the same as the configuration of the game apparatus 300 in FIG. 3 described above.
In addition, as described above, the controller 210 is embedded with a microphone that can be used by switching to a speaker, and can collect surrounding sounds through the hole 216.

The microphone sound acquisition unit 410 acquires the sound signal collected by the microphone of the controller 210 in real time via the wireless communication unit 310.
Specifically, before playing the music game, characteristic sound is supplied from the music playback unit 370 to the display 290, and the microphone sound acquisition unit 410 receives the sound signal collected by the microphone of the controller 210. Start acquisition. Then, the acquired audio signal is sequentially supplied to the display delay calculation unit 361.
Note that the microphone sound acquisition unit 410 may extract only a sound signal in a specific frequency range by a filter calculation or the like and supply it to the display delay calculation unit 361, for example.

The display delay calculation unit 361 calculates the display delay time of the display 290 based on the delay time from when the characteristic audio signal is supplied to the display 290 to when the microphone audio acquisition unit 410 acquires the audio.
For example, as shown in FIG. 11A, the display delay calculation unit 361 calculates the delay of the audio signal collected by the controller 210 (acquired by the microphone audio acquisition unit 410) with respect to the audio signal supplied to the display 290. This delay time is calculated as the display delay time of the display 290.
Further, as shown in FIG. 11B, the display delay calculation unit 361 compares the audio signal supplied to the display 290 and the audio signal collected by the controller 210 in time series, and outputs a plurality of audio outputs. A delay (for example, delays d1 to d3) may be obtained, and an average or deviation may be obtained from these delay times (delays d1 to d3) to calculate the display delay time of the display 290. In this case, the display delay time can be calculated without being significantly affected by noise or the like.

  FIG. 12 is a flowchart showing the flow of the second display delay calculation process executed in game device 400 having the above-described configuration. This display delay calculation process is also started when display delay calculation is instructed by the player from the initial setting screen, for example.

  When the display delay calculation process is started, the game apparatus 400 generates a sound signal having a characteristic sound and supplies it to the display 290 (step S501). For example, the game apparatus 400 generates a sound signal having a characteristic in sound intensity, frequency, or repetition of sound, and supplies the sound signal to the display 290.

  The game device 400 records the audio signal collected by the controller 210 for a predetermined time (step S502). That is, when a characteristic audio signal is supplied to the display 290, the microphone audio acquisition unit 410 starts acquisition of the audio signal collected by the microphone of the controller 210. Then, the acquired audio signal is sequentially supplied to the display delay calculation unit 361 and stored in the internal memory of the processing control unit 360 for a sufficient time (for example, 1 second) at which a display delay can occur.

The game apparatus 400 obtains the delay time of the audio signal collected by the controller 210 with respect to the audio signal supplied to the display 290 (step S503). For example, as shown in FIGS. 11A and 11B described above, the delay time is obtained.
Then, game device 400 calculates the obtained delay time as the display delay time (step S504).

With the display delay calculation process shown in FIG. 12, the sound output from the display 290 can be collected and the display delay time can be automatically calculated. That is, the delay of the audio signal collected by the controller 210 with respect to the audio signal supplied to the display 290 is obtained, and this delay time can be calculated as the display delay time of the display 290.
Then, the game apparatus 400 executes the operation evaluation process as shown in FIG. 8 described above, eliminates the influence of the display delay that occurs according to the display 290 used by the player, and appropriately evaluates the operation of the player. be able to.

(Embodiment 3)
In the second embodiment, the case where the display delay time is automatically calculated by collecting the sound output from the display 290 and obtaining the delay from the supply time has been described.
However, the display delay time may be automatically calculated by another method without being limited to such a method of collecting sound. For example, for example, an image displayed on the display 290 may be captured by the camera 211 of the controller 210 and the display delay may be directly calculated.

FIG. 13 is a schematic diagram showing a schematic configuration of a game apparatus according to the third embodiment of the present invention, which is characterized in that a display delay time is calculated by shooting a video.
The game apparatus 600 includes a wireless communication unit 310, an operation information acquisition unit 320, a display image acquisition unit 610, a music information storage unit 340, an image information storage unit 350, a processing control unit 360, and a music playback unit 370. And an image generation unit 380.
This configuration is a configuration in which the microphone sound acquisition unit 410 of the game apparatus 400 of FIG. 10 described above is replaced with a display image acquisition unit 610.
Further, the camera 211 of the controller 210 has variable sensitivity (light receiving sensitivity, etc.), and by appropriately adjusting this sensitivity, it is possible to take a picture displayed on the display 290.

The display image acquisition unit 610 acquires image information captured by the camera 211 of the controller 210 in real time via the wireless communication unit 310.
Specifically, before playing a music game, a characteristic video with a change in display is generated by the image generation unit 380 and supplied to the display 290, and the display image acquisition unit 610 is connected to the camera of the controller 210. Acquisition of image information taken at 211 starts. Then, the acquired image information is sequentially supplied to the display delay calculation unit 361.
In parallel with this, the processing control unit 360 measures the position of the controller 210, the orientation of the tip, and the like, and confirms that the camera 211 is shooting the video displayed on the display 290. In other words, the display image acquisition unit 610 acquires image information only when the camera 211 captures an image displayed on the display 290.

The image generation unit 380 generates a characteristic video and supplies it to the display 290 before playing the music game. For example, the image generation unit 380 instantaneously switches the entire screen from a low-brightness dark image to a high-brightness bright image, or a light emitting (brightness-bright) object having a predetermined shape in the dark screen (low-brightness dark background). A video signal whose display changes such as displaying one or more is generated.
Note that the characteristic video is not limited to these, and is arbitrary as long as the display changes as appropriate.

The display delay calculation unit 361 calculates the display delay time of the display 290 based on the delay time from the supply of such a characteristic video signal to the display 290 until the display image acquisition unit 610 acquires the same video. To do.
For example, as shown in FIG. 14A, the display delay calculation unit 361 captures an image (acquired by the display image acquisition unit 610) taken by the camera 211 with respect to the video signal (display change) supplied to the display 290. A delay (delay d) of information (display change) is obtained, and this delay time (delay d) is calculated as a display delay time of the display 290.
Further, as shown in FIG. 14B, the display delay calculation unit 361 compares a video signal supplied to the display 290 and the image information captured by the camera 211 in time series, and displays a plurality of delays (for example, delays). d1 to d3) may be obtained, and an average or deviation may be obtained from these delay times (delays d1 to d3) to calculate the display delay time of the display 290.

  FIG. 15 is a flowchart showing a flow of third display delay calculation processing executed in game device 600 having the above-described configuration. This display delay calculation process is also started when display delay calculation is instructed by the player from the initial setting screen, for example.

  When the display delay calculation process is started, the game device 600 generates a video signal of a characteristic video and supplies it to the display 290 (step S701). For example, the game apparatus 600 generates a video signal whose display changes such that the entire screen is instantaneously switched from a low-brightness dark image to a high-brightness bright image, and supplies the video signal to the display 290.

  The game device 600 records image information captured by the camera 211 for a predetermined time (step S702). That is, when a characteristic video signal is supplied to the display 290, the display image acquisition unit 610 starts acquiring image information captured by the camera 211. Note that the game device 600 measures the position of the controller 210, the orientation of the tip, and the like, and confirms that the camera 211 is shooting a video displayed on the display 290, and the image information captured by the camera 211. To get. Then, the acquired image information is sequentially supplied to the display delay calculation unit 361 and stored in the internal memory of the processing control unit 360 for a sufficient time (for example, 1 second) during which display delay can occur.

The game device 600 obtains the delay time of the image information (display change) taken by the camera 211 with respect to the video signal (display change) supplied to the display 290 (step S703). For example, the delay time is obtained as shown in FIGS. 14 (a) and 14 (b).
Then, game device 600 calculates the obtained delay time as the display delay time (step S704).

With the display delay calculation process shown in FIG. 15, the video displayed on the display 290 can be captured by the camera 211 of the controller 210 and the display delay time can be automatically calculated. That is, the delay of the image information (display change) captured by the camera 211 with respect to the video signal (display change) supplied to the display 290 is obtained, and this delay time can be calculated as the display delay time of the display 290.
Then, the game apparatus 600 executes the operation evaluation process as shown in FIG. 8 described above, eliminates the influence of the display delay that occurs according to the display 290 used by the player, and appropriately evaluates the operation of the player. be able to.
