Atmospheric pressure tendency informing apparatus and atmospheric pressure tendency informing method

摘要

An atmospheric pressure tendency informing apparatus and atmospheric pressure tendency informing method inform atmospheric pressure tendency. In one implementation, the atmospheric pressure tendency informing apparatus includes: an informing section, an atmospheric pressure measuring section, an atmospheric pressure inflection point judging section and an informing control section. The atmospheric pressure inflection point judging section judges whether there is an inflection point of atmospheric pressure, based on atmospheric pressure values of at least three points of time including an atmospheric pressure value measured at present. The informing control section controls the informing section to inform the inflection point of atmospheric pressure as the atmospheric pressure tendency based on a judgment result when the atmospheric pressure inflection point judging section judges there is an inflection point of atmospheric pressure.

主权项

1. An atmospheric pressure tendency informing apparatus comprising:
a display which displays an atmospheric pressure tendency; an atmospheric pressure sensor which measures atmospheric pressure each time a predetermined amount of time passes; an atmospheric pressure inflection point judging section which judges whether there is an inflection point of atmospheric pressure, based on atmospheric pressure values of at least three points of time including an atmospheric pressure value measured at present among a plurality of atmospheric pressure values measured successively by the atmospheric pressure sensor; an atmospheric pressure sharp change judging section which judges whether there is a sharp change in the atmospheric pressure based on atmospheric pressure values of at least two points of time including an atmospheric pressure value measured at present among a plurality of atmospheric pressure values measured successively by the atmospheric pressure sensor; and a mark display control section which controls the display to display an inflection point mark showing an inflection point of atmospheric pressure as the atmospheric pressure tendency or a sharp change mark showing a sharp change of atmospheric pressure as the atmospheric pressure tendency based on a judgment result when the atmospheric pressure inflection point judging section judges that there is an inflection point of atmospheric pressure or when the atmospheric pressure sharp change judging section judges that there is a sharp change in the atmospheric pressure, wherein the display includes a plurality of segments adjacent to each other for displaying a segment with an upward arrow and a segment with a downward arrow; and wherein the mark display control section controls the display to display the inflection point mark or the sharp change mark by switching each segment independently between display and non-display.
