Abstract
A navigation device includes a display, a recording medium, a navigation camera, a global positioning system (GPS), and a processor. The processor is operable to determine a current position for generating a navigation route to a destination. Based on a real-time traffic image received from the navigation camera, the processor adjusts a display scale and a display position of the navigation route, superimposes the navigation route on the real-time traffic image to generate a superimposed image, and outputs the superimposed image for viewing on the display and storage in the recording medium.
Claims11
A navigation device comprising:
- a display;
- a recording medium;
- a navigation camera including a camera lens and operable to capture at least a real-time traffic image;
- a global positioning system (GPS) system for receiving at least a GPS signal;
- and
- a processor coupled electrically to said display, said recording medium, said navigation camera and said GPS system, said processor being operable to
- determine a current position based on the GPS signal,
- generate navigation information including a navigation route based on a destination,
- determine a reference point of the real-time traffic image received from said navigation camera, the reference point being associated with a depth of field of the real-time traffic image,
- determine an viewing angle and a zoom scale of the real-time traffic image based on the reference point,
- adjust a display scale and a display position of the navigation route based on the viewing angle and the zoom scale,
- superimpose the navigation route on the display position of the real-time traffic image to generate a superimposed image,
- output the superimposed image on said display, and
- store the superimposed image in said recording medium.

- output the superimposed image on said display, and
- store the superimposed image in said recording medium,
- wherein said processor is operable to
- determine the viewing angle of the real-time traffic image according to position relationship between the reference point and another point on a Y-axis of the real-time traffic image, the Y-axis passing through the reference point, said another point being the center point of the Y-axis on the display screen, and
- adjust viewing angle of the navigation route according to the viewing angle of the real-time traffic image;
- and
- wherein said processor is further operable to
- identify a road in the real-time traffic image,
- determine respective widths at two predetermined positions of the road, and
- determine the zoom scale based on the viewing angle, the distance between the two predetermined positions, and a ratio between the two widths.
