<p>An interframe difference Pij and a motion vector Vhv are supplied to a camera shake detecting circuit (12) from a motion vector detecting circuit (6). The camera shake detecting circuit (12) integrates the interframe difference and forms an evaluation value SIGMA Phv. When none of the blocks of one picture plane satisfy (Vhv < TH1 and SIGMA Phv > TH2) for threshold values TH1 and TH2, the camera shake detecting circuit (12) detects a camera shake. The motion vectors of the blocks are distributed 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 using the correction signal. <IMAGE></p> |
