<P>PROBLEM TO BE SOLVED: To provide a locus display device in which vehicular swept path will not become less-visible even if scale size is smaller, and also actual trajectory is easily determined. <P>SOLUTION: On the map of a display 10, trajectory figures are displayed at both a regularly-spaced trajectory point D and a directional change point E. This regularly-spaced trajectory point D is the point for each regular real interval determined by scale size, however, the smaller scale size the longer that regular real interval. An interval of the trajectory figure associated with the regularly-spaced trajectory point on the display 10 is inhibited, therefore, from being narrower even if the scale size is small. As a result, vehicular swept path will not easily become less-visible even in the case of a smaller scale size. Actual trajectory is also easily determined because the trajectory figure is displayed not only on the regularly-spaced trajectory point D but also on the directional change point E. <P>COPYRIGHT: (C)2011,JPO&INPIT |
