Abstract: In a lens control system, a temporary target position is obtained such that the turning operation is not limited to a value within the movable range of the movable lens in correspondence with the rotational position of the operating member; a normal target position limited to a position within the movable range of the movable lens is set from the temporary target position; and the movable lens is moved to the normal target position. The temporary target position indicates an absolute rotational position of the operating member. If the temporary target position is a position within the movable range of the movable lens (other than the ends), the movable lens is set at the temporary target position, thereby ensuring that the movable lens is set at a fixed position with respect to the corresponding fixed position of the operating member.

Abstract: An image blur correction apparatus that includes a blur detection device, which detects a vibration applied to an optical system and outputs a blur signal in accordance with the detected vibration. Image blur correction is performed to cancel out an image blur that is produced by a vibration applied to the optical system, based on a blur signal output from the blur detection device. A determining device determines whether or not the size of a correction amount, indicating a size of an image blur correction according to the image blur correcting device, exceeds a predetermined threshold value. When the determining device determines that the a size of a correction amount exceeds a predetermined threshold value, the determination device switches from a mode of image blur correction to a mode of a pan/tilt operation.
