NAVIGATION SYSTEM, MOBILE TERMINAL DEVICE, AND ROUTE GUIDING METHOD
First Claim
1. A navigation system comprising:
- a route search server provided with route search means for referencing network data for route searching, and searching a guide route from a departure point to a destination; and
a mobile terminal device provided with guide information storage means for storing guide information that includes guide route data, GPS receiving means for determining a current position, imaging means, display means for displaying a peripheral image captured by the imaging means, and drawing control means for displaying a guide route image on the peripheral image displayed by the display means;
said navigation system characterized in that;
said mobile terminal device has orientation detection means for detecting the orientation of the mobile terminal device when said imaging means captures the peripheral image, and image layout means for determining a display position of the guide route image on the basis of the orientation of the mobile terminal device as detected by said orientation detection means; and
said drawing control means displays an imaging direction guide image for guiding the imaging means toward an orientation at which an image is to be captured by said imaging means on said peripheral image on the basis of the orientation of said mobile terminal device and the orientation of said guide route from the current position when said image layout means determines that said guide route is not included in said peripheral image displayed by said display means.

Abstract
Provided is a navigation system comprising a route searching server and a mobile terminal device. The mobile terminal device includes posture detecting means for detecting the posture of the mobile terminal device at the time when imaging means took a peripheral image, and image layout means for determining the display position of a guide route or a proceeding direction guide image on the basis of the posture of the mobile terminal device detected by the posture detecting means. The mobile terminal device stores the guide route distributed from the route searching server. In case the image layout means discriminates that the guide route is not contained in the peripheral image displayed in display means, drawing control means displays an imaging direction guide image for guiding the direction, in which the imaging means takes the image, on the peripheral image.

11. A guide display method for a mobile terminal device, said mobile terminal device being connected via a network to a route search server provided with route search means for referencing network data for route searching, and searching a guide route from a departure point to a destination;
- said mobile terminal device comprising;
guide information storage means for storing guide information that includes guide route data; GPS receiving means for determining a current position; imaging means; display means for displaying a peripheral image captured by the imaging means; and drawing control means for displaying a guide route image on the peripheral image displayed by the display means;
said route guide display method characterized in that;said mobile terminal device is further provided with orientation detection means for detecting the orientation of the mobile terminal device when said imaging means has captured the peripheral image, and image layout means for correcting the display position of the guide route image so that the upward direction of the peripheral image is vertical based on the angle of the optical axis of said imaging means, shifting said peripheral image by an amount that corresponds to the angle of the optical axis with the horizontal direction, and correcting and determining the display position so that the center of the peripheral image is in the horizontal direction, on the basis of the orientation of the mobile terminal device as detected by said orientation detection means; and said route guide display method comprises a step of said image layout means determining whether said guide route is included in said peripheral image displayed by said display means, and a step of said drawing control means displaying an imaging direction guide image for guiding the imaging means toward an orientation at which an image is to be captured by said imaging means on said peripheral image on the basis of the orientation of said mobile terminal device and the orientation of said guide route from the current position when said image layout means determines that said guide route is not included in said peripheral image displayed by said display means. - View Dependent Claims (12, 13, 14, 15)
