Patent ID: 6989832

Claim:
An entertainment apparatus which displays a moving picture on a display screen of a display device, the moving picture being obtained by photographing an object moving in a virtual three dimensional field, according to manipulation contents of a manipulator received via a controller, by the use of a virtual camera, comprising: object position calculating means for sequentially calculating a position and a moving direction of said object in said three dimensional field; and camera setup means for determining a setup point of said virtual camera in said three dimensional field every time the position and moving direction of said object are calculated by said object position calculating means, while taking a setup point of the virtual camera obtained at least in the last calculation into consideration; wherein, said camera setup means includes means for settling a camera chasing point at a position higher by a predetermined value H than a position to the rear of said object from the position thereof by a distance K, the position being on a line which passes through a newly calculated position of said object by said object position calculating means and is parallel with a newly calculated moving direction of said object, and wherein said camera setup means settles a setup point of said virtual camera at a position approaching said camera chasing point from the setup point of said virtual camera obtained at least in the last calculation; wherein said camera setup means settles the setup point of the virtual camera at a position approaching said camera chasing point from the setup point of said virtual camera obtained at least in the last calculation by a distance L/M, the distance L/M being obtained by dividing a distance L, which is between said camera chasing point and said virtual camera setup point, obtained at least in the last calculation, by a predetermined value M.
