Video game apparatus, background sound output setting method in video game, and computer-readable recording medium storing background sound output setting program
First Claim
1. A video game apparatus in which a specified event is executed in a game space displayed on a monitor, and a plurality of background sounds having different attributes are outputted at a specified output ratio from a plurality of sound output units spaced apart from each other, comprising:
- a recording unit for storing the plurality of background sounds as background sound data, and a background sound control unit for setting the output ratio of levels the background sounds output from at least two of the sound output units based on a relationship of a viewing point and a viewing direction to at least two virtual sound sources, each producing same ones of the background sounds, in the game space while reading the background sound data from the recording unit and outputting the background sounds from the plurality of sound output units, wherein the output ratio of the background sounds is calculated in accordance with a ratio between a first distance and a second distance where said first distance is a space between the viewing point and a first one of the virtual sound sources and a second distance is a space between the viewing point and a second one of the virtual sound sources.

6. A background sound output setting method in a video game in which a specified event is executed in a game space displayed on a monitor, and a plurality of background sounds having different attributes are outputted at a specified output ratio from a plurality of sound output units spaced apart from each other, comprising the steps of:
-
reading the background sound data from a recording unit for storing the plurality of background sounds having different attributes, outputting the read background sound data as background sounds from the plurality of sound output units, and setting the output ratio of levels the background sounds output from at least two of the sound output units based on a relationship of a viewing point and a viewing direction to at least two virtual sound sources, each producing same ones of the background sounds, in the game space, wherein the output ratio of the background sounds is calculated in accordance with a ratio between a first distance and a second distance where said first distance is a space between the viewing point and a first one of the virtual sound sources and a second distance is a space between the viewing point and a second one of the virtual sound sources. - View Dependent Claims (7, 8)

9. A computer readable recording medium storing a background sound output setting program in a video game in which a specified event is executed in a game space displayed on a monitor, and a plurality of background sounds having different attributes are outputted at a specified output ratio from a plurality of sound output units spaced apart from each other, wherein the output ratio of the background sounds output from at least two of the sound output units is set based on a relationship a viewing point and a viewing direction to at least two virtual sound sources, each producing same ones of the background sounds, in the game space while background sound data of the background sounds is read from a recording unit and output from the plurality of sound output units,
wherein the output ratio of the background sounds is calculated in accordance with a ratio between a first distance and a second distance where said first distance is a space between the viewing point and a first one of the virtual sound sources and a second distance is a space between the viewing point and a second one of the virtual sound sources.

13. A video game apparatus for playing a game in a virtual game space displayed on a monitor, comprising:
-
a memory storing image data, a game program, and sound data including at least a first background sound data for producing a first background sound;
a control means for displaying on said monitor at least a portion of said virtual game space based on a viewpoint position and viewpoint direction calculated based on said game program data, said virtual game space having a perimeter boundary;
at least first and second sound output units that are spaced apart from each other;
a background sound control unit for driving said first and second sound output units via first and second channels to output said first background sound from each of said first and second sound output units at respective first and second output levels, said first and second output levels being determined at least in part based on an output ratio determined by a spacial relationship of said viewpoint position, said viewpoint direction and first and second virtual sound sources in said virtual game space;
said background sound control unit setting positions of said first and second virtual sound sources on said perimeter boundary;
an event arena in the virtual game space defining said perimeter boundary, said perimeter boundary being a rectangle; and
said first and second virtual sound sources being located at intersections of a line with said perimeter boundary, said line passing through said viewpoint position and normal to said viewpoint direction. - View Dependent Claims (14, 15, 16)
a first ratio of a first distance between said viewpoint position and said first virtual sound source to a separation distance between said first and second virtual sound sources; and
a second ratio of a second distance between said viewpoint position and said second virtual sound source said separation distance between said first and second virtual sound sources.
