Description

  The present invention relates to a moving image reproducing apparatus and an information recording medium.

Conventionally, games called Adventure Game (AVG) or Novel Game have been provided for information processing apparatuses such as general-purpose computers and game-dedicated devices. Also, this format and other formats (for example, role playing game (RPG), simulation game (SLG), shooting game (STG), puzzle game, action game, etc.) are combined. Many of them are also distributed. Hereinafter, these types of games are collectively referred to as AVG. Such an AVG system is disclosed in the following documents, for example.
Goto Katsuya et al., Sakura Wars 3-Is Sato burning?-Guidebook Volume 1, pages 50-51, Softbank Publishing, Inc., issued May 17, 2001

  FIG. 1 is an explanatory view showing an example of a display screen in such an AVG for an information processing apparatus.

  In the example of the display screen shown in FIG. 1, a background image 102, a character image 103, and a text display 104 are displayed on the AVG display screen 101.

  The display screen 101 in FIG. 1 shows a state of the park as the background image 102. In the center of the display screen 101, a girl character image 103 is displayed so as to overlap the background image 102. Further, a message window is displayed at the bottom of the display screen 101, and a text “[Girl] is yes…” is presented as a text display 104 therein.

  The player of the game reads the displayed text display 104, browses the character image 103 and the background image 102, and inputs an instruction to perform the next display to the information processing apparatus. The AVG program accepts this instruction input, prepares the next scene as appropriate, and displays the background, character, and text on the display screen 101.

  In addition, the AVG program may present options to the user as appropriate. 2 and 3 are explanatory diagrams illustrating examples of display screens on which options are displayed in the AVG.

  In FIG. 2 and FIG. 3, in addition to the background image 102 showing the state in the classroom and the girl character image 103, “listen to an e-mail address” and “listen to a mobile phone number” are displayed as options 105. ing. In FIG. 2, an option 105 “Listen to an e-mail address” is selected by operating a mouse or a keyboard, so this option 105 is highlighted. On the other hand, in FIG. 3, the option “listen to the mobile phone number” is highlighted.

  When the player makes a selection input for selecting one of the displayed options 105 to the information processing apparatus, the story developed in the game changes. That is, the displayed background image 102, the character image 103, the text display 104, and the presented option 105 change according to the selection of the option.

  For example, when the option 105 “Listen to e-mail address” is selected in FIG. 2, “[Masai] Well, sure address is…” is displayed in the sentence display 104 as in the display example shown in FIG. A story with an email address as one opportunity will unfold.

  On the other hand, when the option 105 “Listen to the mobile phone number” is selected in FIG. 3, “[Masai] Well, the sure number is ...” is displayed in the text display 104 as in the display example shown in FIG. A story that uses a mobile phone number as one opportunity develops.

  There has also been proposed a form in which the scene to be reproduced immediately does not change depending on the choice of option. In this case, the scene to be reproduced appropriately changes depending on the selection selected in the past.

  Furthermore, the form which changes the story by the choice 105 selected in the past play, random numbers, etc. is also employ | adopted.

  In addition, the displayed map display or timetable display is used as the display of the option 105, and the player can select the option by selecting a desired point from the map or selecting an action to be performed in a desired time zone. An input form is also adopted.

  As described above, in the AVG for the information processing apparatus, various stories can be provided to the player by various methods, thereby attracting the player's interest and increasing the interestingness felt by the player.

  In some AVGs, the voice of the character is uttered as the speech of the character of the character image 103 displayed on the display screen 101 is displayed on the text display 104. This is a so-called voice function, in which voice information that is performed in advance by a voice actor is prepared for each character line, and the voice information is reproduced when the line is displayed.

  Also in the speech playback of speech, the speech is played back only in a specific scene, the speech is played back for all speech, and the text of the ground (corresponds to a narration or a character monologue played by the player) Various formats are also provided, such as those in which sound is reproduced, and some of them can be selected by the user.

  In addition, since various story developments are available in AVG, players can choose other options by repeating the game from the beginning (or from the saved location) many times in order to see them. It becomes. At that time, the background image 102, the character image 103, the sentence display 104, and the sound that have never been reproduced (the player has never read or viewed) may be reproduced. On the other hand, when the play is repeated, a scene that has been viewed by the user may be reproduced.

  In such a case, a method to lighten the play by replaying the scene that has been read or browsed before (hereinafter referred to as “read part” as appropriate) by fast-forwarding or playing only the synopsis is proposed. Has been. This is a so-called read skip function. Most of the AVGs offered today offer a read skip function.

  In such a read skip function, the background image 102, the character image 103, and the text display 104 are sequentially changed according to the story development without waiting for an instruction input from the user. This process continues until there is some action from the user (for example, a keyboard pressing operation or a mouse clicking operation of the information processing apparatus) or a selection input for selecting one of the options 105 is prompted.

  Conventionally, when waiting for such an instruction input of options from the user, the background image 102, the character image 103, and the text display 104 are generally displayed stationary. Further, even if the character does not stop, conventionally, only a part of the character image 103 is redrawn every predetermined time to make it appear as if the character is blinking, or when the text display 104 or the option 105 is used. In general, the shape of the cursor for making a selection is changed.

  However, there is a great demand for providing an AVG story to a player by reproducing the moving image by creating the background image 102 and the character image 103 together as an animation.

  On the other hand, when an animation is played back, an animation in which an instruction input from the user is acquired without stopping the screen display at the time of inputting an instruction for an option and the user continues to play the movie, and then played back. There is a strong demand to decide.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a moving image reproducing apparatus and an information recording medium.

  In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.

  The moving image reproducing apparatus according to the first aspect of the present invention provides: “Option information that records a plurality of moving image files and is associated with one of the plurality of moving image files, and includes start elapsed time, end elapsed time, and options. A “computer-readable information recording medium that records a plurality of designated option information” is reproduced and includes a reproduction unit, a measurement unit, a selection unit, and a determination unit, and is configured as follows.

  First, the reproducing unit reproduces one of the plurality of moving image files (hereinafter referred to as “reproducing moving image file”) as a moving image.

  On the other hand, the measurement unit measures an elapsed time after the moving image reproduction of the moving image file being reproduced is started.

  Further, the selection unit selects any one of the plurality of option information from the options specified in the option information associated with the playing video file from the start elapsed time specified in the option information. The user is prompted to make a selection until the end elapsed time (hereinafter referred to as “selectable time”).

  Then, the determination unit determines a moving image file to be reproduced next depending on which option has been selected in the past or whether the user has not performed selection within the selectable time. Instruct the playback unit to that effect.

  Here, the selection unit displays the option so as to overlap the video playback by the playback unit within the selectable time and until the user makes a selection, and the selection from the user is performed within the selectable time. If there is, the option display is terminated.

  In the moving image playback apparatus of the present invention, the measuring unit measures the elapsed time based on the number of frames that have already been played back by the playback unit in the moving image file being played back.

  A computer-readable information recording medium according to another aspect of the present invention records a plurality of moving image files, and is selection information associated with any one of the plurality of moving image files. Are recorded, and a program is recorded. The program is configured to cause the computer to function as the moving image playback apparatus.

  The program can be distributed independently of the computer by recording on various computer-readable information recording media (compact disc, flexible disc, hard disk, magneto-optical disc, digital video disc, magnetic tape, semiconductor memory, etc.) Can be sold. It can also be distributed and sold via a computer communication network.

  According to the present invention, a moving image file is reproduced, and a moving image reproducing device in which the moving image file to be reproduced is changed according to input of various options from the user, and the moving image file and the like are recorded and processed by a computer. Accordingly, it is possible to provide an information recording medium that causes a computer to function as the moving image reproducing apparatus.

  An embodiment of the present invention will be described below. In addition, embodiment described below is for description and does not limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

(Computer configuration)
FIG. 6 is a schematic diagram showing a schematic configuration of a typical computer in which the moving image reproducing apparatus according to the present embodiment is realized. Hereinafter, a description will be given with reference to FIG.

  The computer 301 is controlled by a CPU (Central Processing Unit) 302. When the computer 301 is powered on, the CPU 302 executes an IPL (Initial Program Loader) prepared in a ROM (Read Only Memory) 303.

  When the IPL is executed, an OS (Operating System) recorded in the flexible disk (FD) or the hard disk (HD) 305 mounted on the flexible disk drive (FDD) 304 is loaded, and various instructions are input from the user. Can be accepted.

  The user operates the keyboard 306 and the mouse 307 to give various instruction inputs to the computer 301.

  In response to this, the OS causes the CPU 302 to execute programs and various data recorded on the CD-ROM mounted on the hard disk 305 and the CD-ROM (Compact Disk ROM) drive (CDD) 308, and the process of execution. And the result is displayed on the display 309. In addition, the audio processing unit 310 can be used to reproduce audio files and audio tracks recorded on the hard disk 305 and the CD-ROM.

  The CPU 302 uses a RAM (Random Access Memory) 311 as a temporary storage area. The RAM 311 can be used for developing and generating image images to be displayed on the screen and sound to be reproduced.

  Further, the CPU 302 can store information such as processing results and progress in the hard disk 305 in the course of program execution.

  In addition, the CPU 302 itself or a graphics unit to be controlled by the CPU 302 reads out a moving image file from the CD-ROM mounted on the CDD 308 or the hard disk 305, and displays the moving image in parallel with the processing of the CPU 308. It is displayed on the screen 309 so that a moving image can be played back.

  It is to be noted that such a typical computer can be applied not only to the moving image reproducing apparatus of the present invention but also to other information processing apparatuses, and such an embodiment is also included in the scope of the present invention. It is.

  For example, consider the case of a portable game-dedicated device. In this case, game programs and data, various types of moving picture information, and the like are stored in the ROM cassette. When the ROM cassette is mounted on the game dedicated device and the power is turned on, the program stored in the ROM cassette is executed. Information such as processing results and progress is stored in a non-volatile memory such as SRAM (Static RAM) prepared in the ROM cassette or the game dedicated device main body.

(Configuration of video playback device)
FIG. 7 is a schematic diagram showing a schematic configuration of the moving image playback apparatus configured on the computer 301. Hereinafter, a description will be given with reference to FIG.

  The moving image playback apparatus 401 according to the present embodiment targets the information recording medium 402 and includes a playback unit 403, a measurement unit 404, a selection unit 405, a determination unit 406, and a storage unit 407. These units are realized by the CPU 302 included in the computer 301 cooperating with the hardware included in the various computers 301 as appropriate.

  First, the information recording medium 402 can be read by a computer. Typically, a CD-ROM, a DVD-ROM, a ROM cassette, or the like can be used as the information recording medium 402. The information recording medium 402 records the following information.

  (A) Movie file. Multiple records are made. Each can be played back independently. Typically, each moving image file is recorded in a digital moving image format such as AVI (Audio Video Interleaved) format or MPEG (Moving Picture Experts Group) format. In each moving image file, a background image 102 and a character image 103 in conventional AVG are recorded as moving image information, and audio information is included instead of the sentence display 104 (or in addition to the sentence display 104).

  (B) Option information. Multiple records are made. For each option information, the user can select which video file is to be used during video playback and at what timing the video file is displayed during video playback. Is specified. In the AVG system, these pieces of information are generally stored in a file called “script” in a lump or appropriately divided.

  (C) Program. By installing this program in the computer 301, the computer 301 functions as the moving image playback apparatus 401. At the time of installation, in addition to copying the program, option information, a moving image file, and the like may be copied to the hard disk 305.

  Note that the moving image file, option information, and program do not have to be recorded on one information recording medium. For example, at the time of installation, a mode in which a plurality of information recording media such as a so-called “four-disc CD-ROM” is used and files and information recorded thereon are appropriately copied to the hard disk 305. It is also possible to adopt a mode in which only a part of information is read from a part of CD-ROM called a game disc.

  On the other hand, an area for storage is secured in the RAM 311 as the storage unit 407, but various information stored in the storage unit 407 is appropriately written to the hard disk 305 or the like (corresponding to saving the game state). In addition, it is read from the hard disk 305 or the like as necessary (corresponding to loading of the game state).

  The storage unit 407 stores the following information.

  (A) The file name of the movie file currently being played. As will be described later, the file name is set and stored in the RAM 311 when the playback unit 403 starts playback of the moving image.

  (B) File name of a moving image file to be reproduced next. The file name is set and stored in the RAM 311 by interpreting various commands specified in the script file. Specifically, after the user selects all the options associated with the video file currently being played back, the setting is stored at any point before the video playback of the video file currently being played back is completed. Is done.

  (C) Information associated with which option has been selected when the user has previously selected an option within a predetermined time. Information to that effect if you have not selected an option within the specified time.

  (D) The name of a movie file that has been played back in the past. Instead of the movie file name itself, a value may be set in an array area associated with the movie file name. This information is used when skipping read.

The script file contains the following commands.
(A) Movie file designation command. Next, specify the file name of the video file to be played back.
(B) An option designation command. The command has two elapsed times from the start of playback of the video file specified in the video file specification command that was interpreted last before the command (one is “start elapsed time” and the other is “end elapsed time”. In addition to specifying the time, one or more (typically a plurality of) options to be selected by the user are specified. In addition,
(C) Flag update command. After each option is selected, or that no option is specified (hereinafter referred to as “non-selection” as appropriate) is stored as flag information in the RAM 311, or according to selection or non-selection of the option The value stored in the variable area prepared in advance in the RAM 311 is designated to be updated.
(D) Calculation command. With reference to the flag information in the RAM 311 and the value stored in the variable area, it is specified that various four arithmetic operations and logical operations are performed.
(E) Branch command. Depending on the value calculated by the calculation command, the subsequent command is skipped or jumped as appropriate.

  In general, in a script file, a flag update command corresponding to selection or non-selection appears several times after a movie file designation command and a selection command, followed by a calculation command and a branch command, and the branch command is a branch destination. A new moving image file designation command appears, followed by various commands such as.

  The CPU 302 sequentially reads and interprets these various commands stored in the script file and executes them. In this way, as with the conventional AVG system, it is possible to sequentially determine the moving image files to be played one after another depending on selection or non-selection by the user.

  FIG. 8 is a flowchart showing a control flow of the moving image reproduction process executed by the moving image reproducing device 401 according to the present embodiment by reading and interpreting the script file. Hereinafter, a description will be given with reference to FIG.

  First, the CPU 302 sets a predetermined movie file name as the file name of the movie file to be reproduced next in the RAM 311 (step S901), and clears the file name of the movie file currently being reproduced. (Step S902). The moving image file name set in step S901 is the moving image file that is reproduced first, and corresponds to, for example, an opening animation. This is specified by a moving image file setting command arranged at the head of the script.

  Next, the CPU 302 determines whether or not the file name of the moving image file currently being reproduced has been cleared, or whether reproduction of the moving image file currently being reproduced has ended (step S903). If the file name of the movie file currently being played is not specified or if the movie file currently being played is finished playing (step S903; Yes), the file of the movie file to be played next The name is set to the file name of the video file currently being played back (step S904), and an instruction is issued to the playback unit 403 to start playback of the video file having the file name set in step S904 (step S904). Step S905).

  Further, when the moving image reproduction is started, an instruction is issued to the measuring unit 404 to measure the elapsed time after the moving image reproduction is started in step S905 (step S906).

  Video playback processing, elapsed time measurement processing, and subsequent processing are performed in parallel. For these parallel processing, technologies such as time sharing, interrupts, and various multitasking processes are used. This can be realized.

  Further, the CPU 302 determines whether or not there is an unprocessed option designation command for designating a moving image file currently being reproduced (step S907), and if there is one (step S907; Yes), from among them. The one with the smallest start elapsed time is acquired (step S908).

  And it waits until the elapsed time measured by the measurement part 404 reaches the start elapsed time designated by the acquired option designation | designated command (step S909). During the standby, another command may be executed as appropriate, and when the multi-thread processing as described above is executed, the processing may be passed to another thread.

  When the measurement unit 404 has a time measurement mechanism called a multimedia timer, the CPU 302 is interrupted when the start elapsed time is reached, or the control of the thread is intercepted to wait. Techniques such as returning from the state can be used. In addition, in order to synchronize the state of moving image reproduction and the display of options as accurately as possible, it is desirable to cause the measuring unit 404 to measure the number of frames that have been reproduced.

  Now, when the elapsed start time is reached, the options specified in the option specification command are displayed on the screen superimposed on the video playback (step S910), and it is checked whether there has been an option specification input from the user (step S911). If not (step S911; No), it is checked whether the elapsed time measured by the measuring unit 404 has reached the end elapsed time specified in the option specification command (step S912). If not (step S912; No), it returns to step S911. In addition, in the repetition of step S911 to step S913, various techniques relating to option input can be applied.

  On the other hand, when there is an option input (step S911; Yes), the specified option is recorded in the flag area in the RAM 311 (step S914), and when the end elapsed time is reached (step S912; Yes), it is selected. The fact that there was no change (no selection) is recorded in the flag area in the RAM 311 (step S913). Thereafter, the display of options is stopped (step S915), and the process returns to step S907.

  In comparison with FIG. 1 and the like, in the moving image playback apparatus of the present embodiment, when no option is displayed, the background image 102 and the character image 103 (if present) are combined in the moving image file. It is stored as an animation, and the text display 104 is stored as a sound to be reproduced together with the animation in the moving image file. Further, the text display 104 may be incorporated in the animation.

  Therefore, in the conventional AVG, as shown in FIG. 1, FIG. 4, and FIG. 5, in the present embodiment, in the present embodiment, since it is merely a moving image reproduction, it is as if an ordinary movie or television program is played. The story is presented to the user as it is without waiting for input from the user.

  As shown in FIGS. 2 and 3, even when waiting for input of an option, the portion displayed superimposed on the option 105 is also a simple video playback. In spite of waiting, the story is presented to the user as if it were watching an ordinary movie or television program.

  Further, when the choice input from the user is confirmed, or when the user does not select an option within a predetermined time (no selection), the option is not displayed. Also in this case, since the moving image file is reproduced independently of how to select the option, it is possible to continue to give the user an impression as if watching a movie or a television program.

  In other words, it is possible to configure the system so as not to cause problems such as suddenly stopping the screen display, which has been moving smoothly until now, depending on the selection of options, and decreasing the degree of immersion in the story. It is.

  In this way, when the above processing is completed for all of the option designation commands associated with the video file currently being played back (step S907; No), the determination unit 406 stores the RAM 311 recorded in step S914. A value is calculated with reference to the flag information (corresponding to information on options selected or not selected in the past) (step S916). This value is calculated by the CPU 302 interpreting the above calculation command.

  Next, the determination unit 406 determines a moving image file to be reproduced next based on the calculated result value (step S917), and uses the determined moving image file name in the RAM 311 as a moving image file to be reproduced next. The name is set and stored in the name area (step S918). As described above, in the script file, the command to be executed next is determined by the branch command. Therefore, if the branch destination is changed according to the calculation result, the past selection or non-selection history Different video files will be played.

  Then, until the time when the reproduction of the moving image file currently being reproduced is almost finished, the process waits by executing another unprocessed command or the like (step S919), and the process returns to step S903.

  On the other hand, when the reproduction is not completed in step S903 and the name of the currently reproduced moving image file is not cleared (step S903; No), the moving image file is temporarily reproduced, and steps S904 to S919 are performed. In this case, the process returns to step S903 because it is desired to "wait" until the reproduction is completed. It should be noted that such a determination is not necessarily required when waiting in step S919 is performed due to an interrupt or the like.

  In the present embodiment, various configurations are added in order to realize the read skip function more comfortably in the above embodiment.

  First, the storage unit 407 also stores information on a moving image file that has been reproduced in the past, that is, a “read” moving image file. Therefore, the “read” information stored in the storage unit 407 is temporarily stored in the RAM 311, but is saved / loaded with the hard disk 305 or the like according to a user instruction or the like as appropriate.

  The record that the video file has been “read” is recorded in the “read” information in association with the file name of the currently played video file between step S903 and step S904 of the video playback process. Should be added.

  Next, for a “read” video file, the video playback speed is changed. As a result, it is possible to prevent the problem that “when repeatedly playing AVG, it takes time because the same moving image file must be viewed”. Of course, it is also possible to determine whether or not to adopt such a read skip according to the setting of the user.

  In order to change the speed of moving image reproduction, a technique that has already been used in a fast-forward function for DVDs or various moving image files may be applied. Most simply, the playback speed can be changed by skipping and skipping (thinning out) the frame transfer as appropriate.

  There are also various methods for realizing fast-forward playback of audio included in video files so that the pitch does not change (for example, the pitch of the character's voice or BGM does not change). These known techniques can be used.

  For example, it is a method of simply thinning out audio data. In addition, after dividing the audio data at a predetermined time interval, Fourier transform is performed on each segment, and the result of Fourier transform is reproduced for each segment by inverse Fourier transform for a time corresponding to the fast-forwarded playback time. You may employ | adopt the method to do.

In addition, the timing for changing the speed of moving image reproduction is as follows.
(A) When starting moving image reproduction of a new moving image file in step S905, if the moving image file is “read”, the moving image reproduction speed is increased.
(B) In step S910, when the option is displayed, the moving image playback speed is returned to the normal speed regardless of whether or not the moving image file is “read”.
(C) After the selection or non-selection of the option is performed, that is, when the display of the option is stopped in step S913, if the currently played video file is “read”, the video playback speed is set. Make it faster.

  In addition, the above-described change in the video playback speed is made a predetermined time earlier than the time when the option display is started, or is delayed by a predetermined time from the time when the option display is stopped. Even if the playback speed must be changed when moving the video playback target from one video file to another video file, the playback speed can be smoothly increased over a predetermined time. If changed, it is possible to shift to option input without giving the user a sense of incongruity.

  By performing processing in this way, in the case of “read”, the video file can be “read forward” quickly, while the time given when the user selects an option is “read” It is possible to provide a user interface that is easy for the user to be familiar with. This user interface is similar to a conventional AVG that expresses a background or a character by superimposing pictures.

  As described above, according to the present invention, it is possible to provide a moving image reproducing apparatus and an information recording medium. According to the technology of the present invention, in AVG or the like in which each scene is configured as an animation, even when selecting an option, the video playback can be continued as it is, so that the user can play the video without a sense of incongruity. You can see it.
