Abstract
A navigation apparatus and method are provided. The navigation apparatus includes an image acquiring part that acquires an image of a road feature from a vehicle camera. The apparatus also includes a correction distance table that stores a correction distance to correct a difference between a position of a vehicle when the feature disappears from an imaging area of the camera and a guidance output reference position that is a position of the vehicle when the feature disappears from a driver's view. Further, a judging part is included and judges, based on the image acquired by the image acquiring part and the correction distance stored in the correction distance table, whether the vehicle has arrived at the guidance output reference position. Lastly, the apparatus includes a guidance part that provides guidance regarding the traffic light at a predetermined position having the guidance output reference position as a reference.
