ABSTRACT:
An image shake compensation circuit comprising a motion information detector for detecting motion information based on the occurrence of an image shake when the image shake occurs in an encoded video signal, a shake compensator for obtaining a start display position of an image of a present frame according to the motion information detected by the motion information detector, and a decoder for decoding the encoded video signal, correcting a display position of the image of the present frame in response to an output signal from the shake compensator if the encoded video signal has previously been compensated for the image shake and compensating for the image sake if the encoded video signal has not previously been compensated for the image shake.
