Abstract
A fall detecting method and a device for detecting a fall with high accuracy even when an object touches a human or a thing while falling. The fall detecting device has an output detecting part for generating an acceleration detection output after comparing the magnitude of acceleration detected by a three-axis acceleration sensor with a certain threshold, an output interruption correcting part for generating an output interruption corrected acceleration output which is corrected for an interruption when a fall acceleration output recovers within a first predetermined time after the fall acceleration output interrupts, and an output continuation time judging part for generating a fall judgment output when the output interruption corrected acceleration output continues for a second predetermined time longer than the first predetermined time.
