<p>PROBLEM TO BE SOLVED: To display an object to be displayed and required for the play of a game properly and reduce the situation that a player loses sight of a ball. SOLUTION: When a picture image of a field seen from a view point put just above the field is generated, a side line on an upper side is made thicker than a normal line in advance. A picture image obtained by looking the field obliquely and downward from a side is obtained by converting this field in a perspective view. As a result, the side line displayed on an inner side of a screen is not blurred and does not break off and is displayed properly. When a replay picture image is displayed, a picture image in which the side line on the inner side has normal thickness is displayed without displaying a picture image in which the side line on the inner side is thick so as to increase reality.</p> |
