Abstract
A state detection device includes an acquisition part that acquires an acceleration detection value from an acceleration sensor, and a judgment part that judges a running state or a walking state based on the acceleration detection value. The judgment part detects as to whether a positive/negative sign of the acceleration detection value in a first axis reversed in a predetermined judgment period, determines the running state when the sign reverses, and determines the walking state when the sign does not reverse.
