摘要:
In an image stabilizing apparatus in which an actuator for a pivoting gimbal suspension is controlled by a feedback loop, the gain of feedback loop based on the angular position is enhanced when the angular velocity is at a first set value or higher until the angular velocity becomes a second set value or lower, whereby a panning mode is automatically attained when a pan/tilt operation is carried out. Also the gain of feedback loop based on the angular position is enhanced when the angular velocity is enhanced until a lapse of a predetermined time after starting the pivoting control of the gimbal suspension, whereby the behavior of gimbal suspension is stabilized.
