Image stabilizer device, interchangeable lens, and camera system

An interchangeable lens detachable from a camera body to which an interchangeable lens is attached, the interchangeable lens comprising:

• a gyro sensor configured to detect an angular speed of the interchangeable lens and output a shake signal associated with the detected angular speed;
• a lens mount configured to acquire information indicating a set shutter speed from the camera body;
• a filter configured to advance a phase of the shake signal to generate an adjusted signal, and to output the adjusted signal, when the set shutter speed is faster than a predetermined speed;
• a correction lens movable in a plane perpendicular to an optical axis of the interchangeable lens;
• and
• a lens controller configured to correct an influence on an output of the interchangeable lens due to a shake associated with the angular speed, based on the shake signal or the adjusted signal.

A camera system comprising:

• a camera body to which an interchangeable lens is attached;
• and
• an interchangeable lens detachable from the camera body, wherein
• the camera body including:
• a body mount configured to communicate with the interchangeable lens;
• a shutter configured to include a frame having an opening, and a curtain held by the frame, the curtain moving in a direction of opening the opening and in a direction of closing the opening;
• and
• a setting unit configured to set a shutter speed of the shutter, and
• the interchangeable lens includes:
• a lens mount configured to communicate with the camera body through the body mount, and to acquire information indicating a shutter speed set to the camera body;
• a gyro sensor configured to detect an angular speed of the interchangeable lens and output a shake signal associated with the detected angular speed;
• a filter configured to advance a phase of the shake signal to generate an adjusted signal, and to output the adjusted signal, when the set shutter speed is faster than a predetermined speed;
• a correction lens movable in a plane perpendicular to an optical axis of the interchangeable lens;
• and
• a lens controller configured to correct an influence on an output of the interchangeable lens due to a shake associated with the angular speed, based on the shake signal or the adjusted signal.
