Abstract: An image processing apparatus forming a view frustum based on a virtual viewpoint, a gaze-point, and a view-angle, in a virtual space in which objects including a player character and an obstacle are arranged to generates images of the objects arranged in the view frustum, sets the gaze-point to be in a front area of the player character, sets the virtual viewpoint to be at a position separated from the player character by a certain distance in a rear area of the player character, determines whether or not a line segment from the gaze-point to the virtual viewpoint crosses the obstacle, and resets the virtual viewpoint to be at a position of a crossing coordinate nearest to the gaze-point out of crossing coordinates as coordinates at which the line segment crosses the obstacle when the line segment crosses the obstacle to increase the view-angle from a preset reference angle.
