The invention provides an image processing unit for a shooting game in
which suitable images can be displayed according to a given situation,
and in which more exciting and easy-to-manipulate images are displayed.
Coordinate values for objects in three-dimensional virtual space are
established on the basis of prerecorded object shape data, view point
positions are established on the basis of distances x1 and x2 from
predetermined objects defined in three-dimensional virtual space (for
example, the positions are lower when the distance is shorter, and higher
when the distance is longer), the coordinate values established as
described above are received, and the coordinate values are converted to
a visual field coordinate system as seen from the view points established
in the manner described above.
