To accurately measure the offset of an angular velocity sensor mounted in a mobile device in a short time, provided is an offset estimation apparatus including an acquiring section that acquires an output signal from an angular velocity sensor mounted in a mobile device; a hold state judging section that judges a hold state of the mobile device; and an offset estimating section that estimates an offset of the output signal of the angular velocity sensor according to a judgment result of the hold state judging section. Also provided is a method and program. The offset estimation apparatus may include a parameter control section that controls an estimation parameter of the offset estimating section according to the judgment result of the hold state judging section. |
