Patent ID: 8327291

Claim:
An on-vehicle navigation device, comprising: an image generation unit that generates a first image that can be viewed from a driver's seat side and a second image that can be viewed from a passenger's seat side; a display monitor at which the first image and the second image are displayed within a screen; and a decision unit that makes a decision whether a vehicle is in a stationary state or in a traveling state, wherein: the image generation unit includes: a first image generation unit that generates a map image, a second image generation unit that is provided separately from the first image generation unit and generates an image of an icon or a button, and a superimposing unit that is configured to superimpose the image of the icon or the button generated by the second image generation unit over the map image generated by the first image generation unit, the second image generation unit generates an image of a restricted icon or a restricted button, wherein the operation of the restricted icon or the restricted button by the driver is restricted while the vehicle is in the traveling state, when the decision unit makes a decision that the vehicle is in the traveling state, the superimposing unit outputs the map image generated by the first image generation unit as the first image without superimposing the image of the restricted icon or the restricted button generated by the second image generation unit, and outputs the map image generated by the first image generation unit as the second image with superimposing the image of the restricted icon or the restricted button generated by the second image generation unit while a display position of the restricted icon or the restricted button is constantly changed in the second image, when the decision unit makes a decision that the vehicle is in the stationary state, the superimposing unit outputs the map image generated by the first image generation unit as the first image and the second image with superimposing the image of the restricted icon or the restricted button generated by the second image generation unit while a display position of the restricted icon or the restricted button is not constantly changed in the first image or the second image.
