ABSTRACT:
An image-shake correcting device includes a motion-vector detecting circuit for detecting a motion vector relative to pictures, an electronic correcting circuit for electronically correcting an image shake on the basis of the motion vector detected by the motion-vector detecting circuit, an image enlarging circuit for performing enlargement processing on an image signal outputted from the electronic correcting circuit, and a control circuit for controlling a correction step of the electronic correcting circuit on the basis of an image enlargement ratio of the image enlarging circuit to set the correction step to an optimum state.
