ABSTRACT:
An interframe difference Pij and a motion vector Vhv are supplied to a camera shake detecting circuit from a motion vector detecting circuit. A camera shake detecting circuit integrates the interframe difference and forms an evaluation value .SIGMA.Phv. When all blocks of one picture plane satisfy (Vhv<TH1 and .SIGMA.Phv>TH2) for TH1 and TH2, the camera shake detecting circuit detects a camera shake. The motion vector of each block is divided into macroblocks and converted into a motion vector of each macroblock. A camera shake motion vector of the whole picture plane is formed from the motion vector of each macroblock. A correction signal is formed from the detected camera shake motion vector. A camera shake correcting process is executed by the correction signal.
