Patent ID: 8795074

Claim:
A game machine, comprising: a display device configured to display a performance image drawn by mapping a performance object arranged in a three-dimensional virtual space from a virtual camera which serves as a viewpoint in the three-dimensional virtual space; a sound output device configured to output sound information in a performance using the performance object; a storing device configured to store state information on a sound output state of each performance object with respect to a performance time of the object; a sound output performance object identifying device configured to identify a performance object of which the sound information is output, based on the state information stored by the storing device; a camera motion information generating device configured to generate camera motion information for determining a state of operation of the virtual camera, according to sound output state information on the performance object identified by the sound output performance object identifying device in a game using a game medium; a camera direction changing device configured to change a direction of the virtual camera toward a performance object in accordance with the camera motion information generated by the camera motion information generating device; a mapping device configured to map the performance object from a camera position of the virtual camera after changing the direction of the camera by the camera direction changing device; a drawing device configured to draw a performance image that includes the performance object mapped by the mapping device; and a display control device configured to display and control the performance image drawn by the drawing device on the display device, wherein the mapping device maps the performance object by changing the direction of the virtual camera toward the performance object corresponding to the sound output state indicated by the sounds out state information from which the camera motion information is generated.
