PPROBLEM TO BE SOLVED: To realize improvement of operability from the way of displaying a mark so that a player can easily catch a ball according to the guide of the mark. PSOLUTION: At a step S41, a velocity vector VSB1/SBwhen a present ball is moved a single frame later is obtained. At a step S42, a velocity vector VSB2/SBwith the Y component of the vector VSB1/SBas zero is obtained. At a step S43, the value of the vector VSB2/SBis n-folded such as five-folded and it is made to be a vector VSB3/SB. At a step S44, a perpendicular line is drawn perpendicularly from a present ball position to an XZ plane to obtain PSB1/SBas a first positional vector on the XZ plane of the first positional vector. At a step S45, the velocity vector VSB3/SBis subtracted from the first positional vector PSB1/SBto obtain a second positional vector PSB2/SB. By the second positional vector PSB2/SBobtained by calculation like this, the center position PSB2/SB(PSB2/SBX, 0, PSB2/SBZ) of the mark is determined (step S46). PCOPYRIGHT: (C)2004,JPO
