发明名称 FALL DETECTION APPARATUS
摘要 An electronic apparatus includes an acceleration detection unit configured to detect acceleration acting on the electronic apparatus, a noise removal unit configured to remove a noise component from an output of the acceleration detection unit, a first determination unit configured to determine whether output from the noise removal unit indicates acceleration equal to or less than a first acceleration, a second determination unit configured to determine whether output from the noise removal unit indicates acceleration equal to or less than a second acceleration, and a fall state determination unit configured to determine that the electronic apparatus is falling when the first determination unit detects that output from the noise removal unit is equal to or less than the first acceleration, or when the second determination unit determines that output from the noise removal unit is equal to or less than the second acceleration.
