Image pickup apparatus and image stabilization method

An image pickup apparatus comprising:

• a photographing optical system configured to form an optical object image;
• an image pickup device configured to photoelectrically convert the object image to generate an image pickup signal;
• an image blur detection sensor that detects amounts of image blur of the object image in a translation direction and a rotation direction on an image plane of the image pickup device;
• an optical correction actuator configured to cause the image pickup device to move in a plane vertical to an optical axis of the photographing optical system to perform optical correction of image blur in the translation direction and, when necessary, further perform optical correction of image blur in the rotation direction;
• an electronic correction circuit that cuts out a part of image data obtained based on the image pickup signal and cause the part to be an output image;
• and
• a walking detecting circuit that detects which state the image pickup apparatus is in, a walking state or a non-walking state, wherein
• if the walking detecting circuit detects that the image pickup apparatus is in the walking state, an amount of correction of the image blur in the rotation direction by the optical correction actuator is caused to be smaller, and an amount of correction of the image blur in the rotation direction by the electronic correction circuit is caused to be larger than a case where the walking detecting circuit detects that the image pickup apparatus is in the non-walking state.
