发明名称 ELECTRONIC APPARATUS, SIGNAL COMPENSATION DEVICE, AND SIGNAL COMPENSATION METHOD
摘要 <p><P>PROBLEM TO BE SOLVED: To provide an electronic device capable of preventing failures due to temperature drift of an angular velocity sensor, and to provide a signal compensation device and a signal compensation method. <P>SOLUTION: The electronic apparatus is operated by moving within a space, while a user holds it. The apparatus includes an angular velocity sensor outputting a first signal according to the rotational angular velocity; a memory means memorizing a second signal data output from the angular velocity sensor that is in a stationary state in advance as a reference value for calculating the angular velocity; an acceleration sensor detecting stationary state inside the space of the device; and a calculating means computing a new reference value for compensating the first signal using the data of the first signal output from the angular velocity sensor at that time, if stationary state is detected, based on displacement of output voltage per unit time of the acceleration sensor. <P>COPYRIGHT: (C)2010,JPO&INPIT</p>
