Abstract
A motion state detecting method using a detector, detecting one of a conducting state and a non-conducting state according to a movement of an object, includes: first processing to measure either a first number of times, indicating the number of times of change from the conducting state to the non-conducting state per unit time or a second number of times that is the number of times of change from the non-conducting state to the conducting state per the unit time; and second processing to regard either the first number of times or the second number of times as a change determination value and change a length of the unit time based on the change determination value; wherein a proportion of time of the conducting state per the unit time or the non-conducting state per the unit time is changed by changing the length of the unit time.
