An image pickup apparatus includes an image pickup element for converting an optical image on a focal plane into an electrical image signal and outputting the electrical image signal. A vibration sensor detects a vibration amount of an image pickup apparatus main body, and an optical axis decentering member is provided for decentering an optical axis to cause the optical image to coincide with a predetermined position on the focal plane of the image pickup element. A driving control circuit controls a decentering amount of the optical axis decentering member on the basis of a detection output from the vibration sensor, and a control circuit controls the driving control circuit so that the decentering member is operated if the image pickup element is outputting the electrical signal.
