PROBLEM TO BE SOLVED: To provide an intersection guide device in vehicle navigation using a camera, in which the center point of the intersection is determined based on a vehicle forward picture acquired with a camera and a traffic sign recognized in the forward picture, and the turn-by-turn information of the vehicle is overlaid on the center point, thereby minimization of the disturbance of the driver and correct road guidance for him in the intersection. SOLUTION: The device includes an intersection recognition means for determining whether the vehicle approaches the intersection within a previously set distance or not, based on the present position information of the vehicle and the intersection position information obtained by a navigation information means, an intersection center point recognition means for recognizing the center point of the intersection based on the traffic sign recognition information obtained by a picture recognition means, a control means for changing the turn-by-turn information represented by the center point of the intersection, the intersection position information, and the present position, corresponding to the approach of the vehicle to the intersection, and a direction display means for overlaying the turn-by-turn information changed by the control means on the forward picture to present the overlaid information via a picture output means.
