An image processor displays the behavior of a character imitating an actual player in a virtual three-dimensional space. The image processor discriminates whether or not the inter relationship (distance, etc.) between a target (for example, a competing character or ball) having a relation with the character through the game and the character or a relation regarding the details of the game is in aprescribed state meeting a prescribed condition (S21-S24, etc.) and, when the processor discriminates the prescribed state meeting the prescribed condition, the processor directs the eyes of the character to the target (S25, S26, S28, etc.). This image processor is particularly suitable for soccer games.
