A tide level calculation unit obtains a tide level at an interval of a time set by a display time setting unit on the basis of a date/time inputted from a date setting unit, a point inputted by a point setting unit and tidal component data at this point. Then, a tide level difference calculation unit obtains a tide level difference from a difference between a maximum value and a minimum value of tide levels, a tide level range displayed by one segment is obtained by dividing this tide level difference by a segment count along a tide-level-axis, and the tide level range is changed. Accordingly, dynamic display utilizing a display area of a display unit to the full can be attained.

Abstract: The timing of a tide is calculated depending on a user-selected geographic region and calendar date. Tide data is stored in memory for each geographic region available for selection by the user. The timing of a tide is calculated by determining first and second tide level data using a tide level estimating equation. The first tide level data is dependent on the selected calendar date and the stored tide data that corresponds to the selected geographic region. The second tide level data having a time interval that is shorter in duration than a time interval of the first tide level is determined data again using the tide level estimating equation. The timing that a tide corresponding to the selected geographic region and calendar date occurs is then calculated dependent on the second tide level data. Thus, an accurate calculation of the timing of a desired tide is obtained for the user-selected geographic region and calendar date.
