Abstract:
1. An electronic device with a built-in inclination sensor, comprising: an inclination sensor that calculates inclination by a single detection of acceleration without using a magnetic field; a control unit that performs predetermined control based on a value calculated by the inclination sensor; a case that includes the inclination sensor and the control unit inside thereof; and a suspension portion that suspends the case, wherein the control unit performs correction control of a reference value of the inclination sensor based on a vertical direction determined by gravity and the value calculated by the single detection by the inclination sensor in a state in which the case is suspended by way of the suspension portion and has come to rest, thereby establishing the vertical direction, wherein when the case is suspended by way of the suspension portion, the control unit determines whether an inclination angle related to a value calculated by the inclination sensor coincides with a predetermined inclination angle, and in a case of having determined not to coincide, the control unit calculates an amount of deviation from the predetermined inclination angle, and performs the correction control based on the amount of deviation.
