When one of the directors is selected by a game player, the corresponding presentation expressing data is read out using the identification data of the selected director. CG images are produced based on the read-out presentation expressing data and displayed. If the game player selects another director during the progress of the game scenario, the corresponding presentation expressing data is read out so that CG images are produced based on the presentation expressing data of the different director and displayed.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an image processing technique which is applied to a video game apparatus, a reproducing apparatus of a CG (Computer Graphic) movie, or the like.

2. Description of the Related Art

In recent years, role-playing games have been actively developed, wherein, for example, a player operates behavior of a player character appearing in a game so that the player character fights a counterpart character, or a player grows up a player character in a game. In recent video game apparatuses, entertainment factors are enhanced by, not only operating behavior of a character, but also making a game itself storyful as well as using a three-dimensional CG image processing technique to produce game images in which characters, background environments, etc. move and change realistically. Further, it has also been attempted to produce CG movies using the three-dimensional CG image processing technique.

In general, the CG images to be used for those purposes are produced based on data which are prepared by a director or a person in charge under the direction of the director according to a scenario for specifying expressing manners of characters, background environments, etc. This is like a film director takes a motion picture by, for example, instructing behavior and expression to actors and actresses, utilizing cameraworks, such as changing a camera position and zooming, and using lighting and properties for enhancing presentation effects.

As described above, the CG images to be used in the storyful video game apparatus or the CG movie are produced under the direction of a director according to a certain scenario. It is often experienced that even if a scenario is the same, the presentation effects, such as the camerawork effect and the property effect, for images thus produced differ depending on directors so that different impressions are given to a viewer.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Now, a preferred embodiment of the present invention will be described hereinbelow with reference to the accompanying drawings, wherein the present invention is applied to a video game apparatus.

In this embodiment, presentation expressing data including expression data for characters and variation data for background environments etc. are prepared in advance under the direction of different directors A, B and C according to the same game scenario, and stored in a CD-ROM as one example of a storage medium.

Further, in this embodiment, the characters, the background environments, etc. are formed by polygons, and movement of the characters and variation of the background environments etc. are realized by a program for moving coordinates or changing a shape of each polygon, the expression data and the variation data, all of which form the presentation expressing data. Accordingly, as opposed to movie format data commonly used in a personal computer, image data are not stored as they are.

The expression data are data for specifying viewing points, viewing angles, kinds of cameras (virtual), display sizes, zooming magnitudes, display timings, display time periods, etc. necessary for forming game images including characters. The variation data are data for specifying background environments etc., kinds and intensities of lighting, kinds of properties, kinds and magnitudes of sounds, etc. which can change following behavior of characters.

The presentation expressing data are stored so as to correspond to progress data of a game scenario and director identification data for identifying each of the directors, so that required presentation expressing data can be read out using these data as key data.

The foregoing correspondence between the data can be easily achieved by linking the data using time element data associated with the progress of the game scenario.

The CD-ROM also stores a program (program codes) which, cooperatively with a basic apparatus being a computer, constitutes a video game apparatus when read into the basic apparatus. Hereinafter, this program will be referred to as “game program”. In the following description, it is assumed that the game program also includes data and control parameters necessary for execution thereof.

Referring now to FIG. 1 , the basic apparatus for constituting the video game apparatus according to the preferred embodiment of the present invention will be first described hereinbelow. As the basic apparatus, one described in, for example, JP-A-8-2 12377 can be used.

The basic apparatus reads out the game program from the foregoing CD-ROM which is exchangeable and portable, and executes it so as to produce, display and control CG images.

As shown in FIG. 1 , the basic apparatus 1 comprises a main control section 10 , an image processing section 20 , a sound processing section 30 , a disk control section 40 , a communication control section 50 and a main bus B connecting the foregoing functional blocks 10 to 50 to allow two-way communications among them.

The main control section 10 comprises a CPU 11 , a peripheral device controller 12 for carrying out an interrupt control, a DMA (direct memory access) transfer control, etc., a main memory 13 for temporarily storing the game program and the presentation expressing data read out from the CD-ROM 44 , and a ROM 14 storing an operating system (OS) etc. for managing the image processing section 20 , the sound processing section 30 , etc. The CPU 11 is a RISC (reduced instruction set computer) CPU, executing the OS stored in the ROM 14 to control the basic operation of the whole apparatus and further executing the game program stored in the main memory 13 to realize a plurality of functional blocks which will be described later.

The image processing section 20 comprises a geometry transfer engine (GTE) 21 carrying out high-speed coordinate transformation relative to data stored in the main memory 13 and so forth, a graphics processing unit (GPU) 22 for drawing three-dimensional CG images composed of combinations of polygons, such as triangles and quadrilaterals, and sprites (which will be included in the concept of polygons hereinafter) according to drawing commands from the CPU 11 , a frame buffer 23 for temporarily storing the three-dimensional CG images drawn by the GPU 22 , and an image decoder (MDEC) 24 for decoding compressed image data as requested. A display unit 25 reads out the three-dimensional CG images data stored in the frame buffer 23 and displays them.

By consecutively executing the drawing by the GPU 22 and the storing into the frame buffer 23 , the three-dimensional CG images including motion image elements can be displayed on the display unit 25 .

The sound processing section 30 comprises a sound processing unit (SPU) 31 for producing sound effects, voices, sounds, etc. according to background environment data about acoustics, a sound buffer 32 for temporarily storing sound effect data and other tone generator data, and a loudspeaker 33 for outputting the sound effects etc. produced at the SPU 31 . The SPU 31 has an ADPCM decoding function of, for example, reproducing tone generator data subjected to adaptive differential pulse code modulation (ADPCM), a function of producing sound effects etc. by reproducing tone generator data stored in the sound buffer 32 , a modulating function of modulating and reproducing tone generator data stored in the sound buffer 32 , and so forth. Given such functions, the SPU 31 can be used as a sampling tone generator for producing sound effects etc. based on tone generator data stored in the sound buffer 32 .

The disk control section 40 comprises a disk drive 41 for reproducing the game program, the presentation expressing data, etc. stored in the CD-ROM 44 , a CD-ROM decoder 42 for decoding the reproduced data when error correcting codes (ECC) are added thereto, and a CD-ROM buffer 43 for temporarily storing the reproduced data from the disk drive 41 before storing them into the main memory 13 . The CD-ROM decoder 42 constitutes a part of the sound processing section 30 . An audio output from the CD-ROM decoder 42 is once inputted into the SPU 31 where it is mixed with an SPU output, and then inputted into a reverb unit so as to be a final audio output.

The communication control section 50 comprises a communication control device 51 for controlling communication with the CPU 11 via the main bus B, a controller 52 used for inputting commands from a game player, and a memory card 53 for storing the setting of a game etc.

The controller 52 is an interface for inputting commands from the player and includes a start key for commanding the start or restart of a game, a reset key for commanding the reset of the game, a selection key for commanding movement of a character in vertical and lateral directions and moving a cursor to desired one of menus or items, a command key for commanding detailed behavior of the character and commanding a selected menu, and so forth. The controller 52 transmits the state of each key to the communication control device 51 in synchronous communication.

The communication control device 51 notifies the state of each key of the controller 52 to the CPU 11 . In this fashion, the commands from the player are given to the CPU 11 so that the CPU 11 performs an image displaying process and a game developing process based on the executing game program according to the commands from the player.

If the setting of a game progressing according to a game scenario, the final or intermediate result of the game or the like needs to be stored, the CPU 11 sends the necessary data to the communication control device 51 which then stores the data sent from the CPU 11 into the memory card 53 . Since the memory card 53 is separated from the main bus B, it can be loaded or unloaded with the power being on. Accordingly, the setting of the game etc. can be stored in a plurality of memory cards 53 .

The basic apparatus 1 further comprises a parallel input/output (I/O) port 61 and a serial input/output (I/O) port 62 connected to the main bus B, respectively. Connection to a peripheral device can be achieved via the parallel I/O port 61 , while connection to another video game apparatus can be achieved via the serial I/O port 62 .

In the foregoing basic apparatus 1 , when the power gets on or a reset process is executed while the CD-ROM 44 is loaded in the disk drive 41 , the CPU 11 executes the OS stored in the ROM 14 to first initialize the whole apparatus, then control the disk control section 40 to read out the game program stored in the CD-ROM 44 and transfer it into the main memory 13 , and then execute it. In this event, the presentation expressing data are also read into the main memory 13 upon occasion. Through the execution of the game program, the CPU 11 realizes the functional blocks as shown in FIG. 2 so that the video game apparatus generally designated by numeral 2 is presented.

As shown in FIG. 2 , the video game apparatus 2 comprises a scenario managing section 211 , an image interface section 212 , a command analyzing section 213 , a director data storing section 214 and an image managing section 215 .

The scenario managing section 211 monitors time elements after the start of the game and the state of execution of the game program so as to manage the progressing state of the game scenario. The image interface section 212 produces images of various menus and items for allowing the player to input his/her intentions via the controller 52 during the managed game scenario progress and sends them to the image managing section 215 .

In this embodiment, the image interface section 212 produces, in addition to images of characters operated by the player, an image of a director selecting menu 251 as shown in FIG. 3 for selecting game images produced by a director desired by the player and an image of a director setting menu 252 as shown in FIG. 5 . The director selecting menu 251 is displayed in a given scene of the game scenario, such as at the start of the game. The image interface section 212 further produces an image of an item which is displayed at a part of a game image at a given timing, such as at the time of development into a new scene or at the time of a climax. By moving a cursor to select this item, the director selecting menu 251 is displayed according to an intention of the player.

In FIG. 3 , reference signs 71 a to 71 c represent director selecting buttons for selection among directors A to C, 72 a to 72 c selecting buttons for Introduction data introducing features of the presentation expressions of the respective directors A to C (for example, director A is gentle in camerawork, director B uses zooming frequently, director C uses many properties - - - ), 73 a cancel button for canceling the selection, and 74 a selection finish button for finalizing the selection. =The command analyzing section 213 analyzes command data inputted from the controller 52 via the communication control device 51 so as to execute required data controls. The command data include, for example, a command for displaying the director selecting menu 251 , a command for director introduction, a command for director selection, a command for start/stop/restart/end of the game, a command for behavior of a player character, a command for selection of speech/ behavior of the player character and a command for item selection.

When the command for director introduction is inputted, the command analyzing section 213 causes the director data storing section 214 to send the corresponding introduction data to the image control section 215 , so that the introduction data requested by the player is displayed on the display unit 25 . When the command for director selection is inputted, the command analyzing section 213 sends identification data of the selected director to the image managing section 215 .

Further, the command analyzing section 213 loads into the main memory 13 the game program from the CD-ROM 44 and the saved data from the memory card 53 upon detection of the start or restart of the game. Further, upon detection of the stop or end of the game, the command analyzing section 213 saves into the memory card 53 data representing the progressing state of the game and the current director as described above.

Using the director identification data sent from the command analyzing section 213 as key data, the image managing section 215 reads out the corresponding presentation expressing data from the CD-ROM 44 via the CD-ROM decoder 42 . Then, the image managing section 215 produces CG images (game images) using the read-out presentation expressing data with the assistance of the GTE 21 and GPU 22 and displays them on the display unit 25 . Further, the image managing section 215 displays upon occasion the director selecting menu 251 , the director introduction data, the item for displaying the director selecting menu 251 , etc. on the display unit 25 .

Now, a game procedure in the foregoing video game apparatus 2 will be described with reference to a flowchart shown in FIG. 4 .

In FIG. 4 , when the start or restart of a game is commanded from the player via the controller 52 (Yes at step S 101 ), the command analyzing section 213 judges whether it is a new game or a continued game (step S 102 ). If it is the new game, the command analyzing section 213 notifies it to the image managing section 215 which then displays an image for Initial setting including a player registration step S 103 ). Thereafter, the director selecting menu 251 shown in FIG. 3 is displayed (step S 104 ) so as to allow the player to select a desired director. In this event, if the player selects one of the selecting buttons 72 a to 72 c , the corresponding director introduction data is displayed. The selection of one of the buttons on the director selecting menu 251 is carried out by moving a cursor to be on the corresponding button and then designating the selection finish button 74 on a display screen or on the controller 52 .

If the player does not select the director, the first director (director A) is automatically selected as shown in FIG. 3 .

When the director is selected, the image managing section 215 reads out the corresponding presentation expressing data from the CD-ROM 44 in order using identification data of the selected director as key data and produces game images for displaying on the display unit 25 (step S 105 ). Now, the game is started.

On the other hand, if it is the continued game as judged at step S 102 , saved data relating to the subject player is read out from the memory card 53 (step S 106 ) so that a game image corresponding to a director at the time of the interruption of the game is displayed (step S 107 ). Accordingly, the player can restart the game from the time point of the interruption of the game.

As the game progresses according to a game scenario to reach a predetermined item display scene (Yes at step S 108 ), the image managing section 215 displays the item for displaying the director selecting menu 251 (step S 109 ).

If selection of the item by the player is detected (Yes at step S 110 ), the director selecting menu 251 is displayed (step S 111 ).

Then, if a director other than the current director is selected by the player on the director selecting menu 251 (Yes at step S 112 ), the presentation expressing data to be read out from the CD-ROM 44 is switched (step S 113 ). Specifically, using identification data of the selected director as key data, the image managing section 215 reads out corresponding presentation expressing data from the CD-ROM 44 and produces game images based on the presentation expressing data of the different director for displaying on the display unit 25 . On the other hand, if the item is not selected at step S 110 (No at step S 110 ) or another director is not selected at step S 112 (No at step S 112 ), the presentation expressing data of the current director is continued to be read out from the CD-ROM 44 (step S 114 ).

The foregoing processes are repeated until the stop or end of the game is commanded via the controller 52 (No at step S 115 ).

If the stop or end of the game is commanded (Yes at step S 115 ), data up to then is saved if necessary (steps S 116 , S 117 ) and the routine is terminated.

In the foregoing game procedure, the director selecting menu 251 can be displayed per given scene. On the other hand, it may be arranged that the item for displaying the director selecting menu 251 is constantly displayed at a part of game images after the start of the game so that the player can switch the director arbitrarily.

Further, it may be arranged that game images produced by a plurality of directors are switched in sequence for displaying on the display unit 25 . Specifically, as shown in FIG. 5 , for example, an image of the director setting menu 252 for setting a director for each of scenes is prepared in advance at the image interface section 212 , and the player sets a director per scene on the director setting menu 252 at the start of the game. Then, when each of the scenes is reached, identification data of the corresponding director is sent to the image managing section 215 from the scenario managing section 211 . In FIG. 5 , numeral 75 represents a region for setting the directors corresponding to the scenes, respectively.

For example, in FIG. 5 , a director A is used in Scenes 1 and 2 , a director B is used in Scene 3 , a director C is used in Scene 4 , and the director A is used in Scene 5 . FIG. 6 shows a sequence of displaying game images corresponding to FIG. 5 . Specifically, presentation expressing data of the initially set director (director A) is first read out and game images are produced based on the read-out data and displayed (step S 201 ). Then, presentation expressing data of the corresponding directors are automatically read out according to the contents of the director setting menu 252 , and corresponding game images are produced and displayed on the display unit 25 (steps S 202 to S 206 ).

In FIG. 5 , if an initial value setting button 76 is selected, the presentation expressing data of the initially set director continues to be read out irrespective of the contents of the director setting menu 252 , so that the game images produced by the same director continue to be displayed. In FIG. 5 , numeral 77 represents a cancel button for canceling the setting of the directors, and 78 a setting finish button for finalizing the setting of the directors.

As described above, in the video game apparatus 2 according to this embodiment, a plurality of presentation expressing data produced under the directions of different directors are stored so as to correspond to the game scenario and the identification data of the respective directors. When one of the directors is selected by the player, the presentation expressing data of the selected director is read out to produce the corresponding game images. Therefore, the player can enjoy the game images with the different presentation effects even if the game scenario is the same.

Further, since the presentation expressing data can be switched per given scene of the game scenario, game images produced by different directors can be enjoyed in the respective scenes.

Further, the presentation expressing data include programs and data for converting image elements in the form of polygons into images including three-dimensional motion image elements, and CG images are produced based on such presentation expressing data. Accordingly, even if it is designed to display CG images produced by many directors, the required memory capacity is not so increased. Therefore, the CG images produced in diversified expressing manners according to the same scenario can be reproduced from one CD-ROM. Further, the presentation expressing data of various directors can be stored in an exchangeable portable storage medium, such as the CD-ROM, per game scenario. Thus, by loading the storage medium into the basis apparatus 1 shown in FIG. 1 , the video game apparatus 2 with diversified CG images can be easily realized.

As appreciated, the foregoing preferred embodiment is suitable for a case wherein the scenes of the game scenario progress while the player does not move the characters so aggressively.

However, the present invention is not limited thereto. Specifically, it may be possible to hold presentation expressing data produced by a plurality of directors, corresponding to only a part of a game scenario. More specifically, CG images are normally produced using only one kind of presentation expressing data (common presentation expressing data) prepared by a certain director and, only in a scene where the player is hardly allowed to operate behavior of the characters, presentation expressing data of one director is selected from those prepared by a plurality of directors.

The present invention is applicable to not only a video game apparatus as in the foregoing preferred embodiment, but also a reproducing apparatus of a CG movie. In case of the CG movie reproducing apparatus, since the processes following the player's operation of character behavior, required in the video game apparatus, are not required, the present invention can be carried out more easily. Like the video game apparatus, CG images produced in diversified expressing manners can be reproduced from one CD-ROM, and further, presentation expressing data of various directors can be stored in an exchangeable portable storage medium per scenario and, by loading the storage medium, a CG movie reproducing apparatus with diversified CG images can also be realized.

While the present invention has been described in terms of the preferred embodiment and the modifications thereof, the invention is not to be limited thereto, but can be embodied in various ways without departing from the principle of the invention as defined in the appended claims.
