Abstract
A gimbal device includes a controller for controlling a gimbal mechanism to which an imaging device is fixed. The controller includes an angular velocity signal acquisition unit, a relative angle acquisition unit, and an angular velocity signal synthesizer. The angular velocity signal acquisition unit acquires first to third angular velocity signals. The relative angle acquisition unit acquires first and second relative angles. The angular velocity signal synthesizer generates from the first to third angular velocity signals and the first and second relative angles, first to third rotational shift angular velocity signals which are signals of a first rotational shift angular velocity about an axis parallel to a first correction axis, a second rotational shift angular velocity about an axis parallel to a second correction axis, and a third rotational shift angular velocity about an axis parallel to a third correction axis, respectively.
