A route guidance apparatus and method are provided. The route guidance apparatus includes an image acquisition unit that collects image data of an area in front of a vehicle using a camera and a driver view recognition unit that calculates the range of a driver viewing angle by detecting a driver eye height driver a driver's gaze direction. An image processing unit extracts a region of interest corresponding to the range of the driver viewing angle from the image data and generates a route guidance image by overlaying a direction indicator corresponding to a driving route on the region of interest. A display unit outputs the route guidance image.
