  • Patent number: 8326028
    Abstract: It is possible to compatibly set multiple “dropout” color ranges and “non-dropout” color ranges and uniquely determine a dropout boundary. An object of the present invention is to greatly conserve maintenance cost of adding a new dropout form after apparatus operations. A conventional technology aims at assuring relation to a predetermined color region, determining the presence or absence of contention, or uniquely settling a dropout boundary. The present invention provides a means for supplying levels to a “dropout” color range and a “non-dropout” color range. A registered color range histogram can be quasi-three-dimensionally visualized so that an operator can make adjustment by viewing a contention determination result and an image.

  • Publication number: 20040169653
    Abstract: In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale.

  • Patent number: 6756919
    Abstract: A map display apparatus includes a map data memory which stores map data necessary for plotting a map of a predetermined region; a map display which reads map data out of the map data memory and plots a bird's-eye view display by projecting the map data read out from the map data memory onto a projection plane which makes a projection angle with a plane of the map data read out from the map data memory, the projection angle being greater than 0° and less than 90°, the bird's-eye view display including identifying marks which identify items in the bird's-eye view display; and an identifying mark overlap preventer which prevents identifying marks from overlapping one another in the bird's-eye view display.
