Navigation device
First Claim
1. A navigation device comprising:
- means for measuring a present position of a movable body equipped with said navigation device;
means for displaying map information;
means for storing destination information including at least positional information of a destination to which said movable body is scheduled to move, and an estimated time to arrive at the destination; and
a control means for controlling said displaying means to display the map information, which corresponds to the measured present position, and display the measured present position on the displayed map information, selecting destination information, which corresponds to a destination located in said displayed map information, from the stored destination information, and controlling said displaying means to display the selected destination information on the displayed map information,wherein said control means calculates a distance from the measured present position to the destination and a changing rate of the calculated distance, judges whether or not said movable body has passed the destination if the changing rate is within a predetermined threshold range and a minimum value of the calculated distance is smaller than a predetermined threshold value to output a judgement result, and controls said displaying means to change the brightness of the displayed destination information depending on the judgment result.

20. A navigation device comprising:
-
means for measuring a present position of a movable body equipped with said navigation device; means for displaying map information; means for storing destination information including at least positional information of a destination to which said movable body is scheduled to move, and an estimated time to arrive at the destination; and a control means for controlling said displaying means to display the map information, which corresponds to the measured present position, and display the measured present position on the displayed map information, selecting destination information, which corresponds to a destination located in said displayed map information, from the stored destination information, and controlling said displaying means to display the selected destination information on the displayed map information, wherein said control means calculates a distance from the measured present position to the destination and a changing rate of the calculated distance, judges whether or not said movable body has passed the destination if the changing rate is within a predetermined threshold range and a minimum value of the calculated distance is smaller than a predetermined threshold value to output a first result of judgment, compares the estimated time and a present time, judges whether or not it has passed the estimated time to output a second result of judgment, and controls said displaying means to change the brightness of the displayed destination information depending on the first and second results of judgment.
