Camera controller

A camera controller mounted in an imaging apparatus and controlling a camera-shake correction, comprising:

• an angular shake operation part which calculates an angular shake amount of the imaging apparatus on the basis of an output signal of an angular velocity sensor mounted in the imaging apparatus and detecting an angular velocity;
• a shift shake operation part which calculates a shift shake amount of the imaging apparatus in accordance with a first operation system or a second operation system on the basis of an output signal of an acceleration sensor mounted in the imaging apparatus and detecting an acceleration;
• a combination part which combines the angular shake amount and the shift shake amount to output a combined shake amount;
• an operation system setting part which sets an operation system of the shift shake operation part on the basis of the combined shake amount;
• and
• a control part which controls an actuator driving a corrective lens included in an imaging optical system on the basis of a camera-shake correction amount correcting the combined shake amount,
• wherein the shift shake operation part includes a first imperfect integrator, and
• wherein in the second operation system of the shift shake operation part, the operation system setting part increases or decreases a cut-off frequency of the first imperfect integrator more than in the first operation system of the shift shake operation part.
