<P>PROBLEM TO BE SOLVED: To provide an image pickup device capable of improving camera shake corrected image quality. <P>SOLUTION: A first shake detection circuit 12 extracts an effective band as shake and vibrations from a signal detected by an angular velocity sensor 11, and a lens control circuit 14 calculates a target position of shake correction on the basis of the signal and drives a lens 16 through an actuator 15 so as to correct blur at an image formation position by the shake. A second shake detection circuit 13 extracts the signal by a cutoff frequency different from that of the first shake detection circuit 12, a correction function calculation circuit 19 generates a locus of an actual drive position of the lens and a locus of an output signal of the second shake detection circuit during exposure, performs differential processing between the both loci at the same position and calculates a point image function and a function of its inverse characteristic, and a signal processing circuit 20 applies an operation by a correction function calculated by the correction function calculation circuit 19 to an image having blur that results from a shake of an image pickup element 18 and displays the operation in an image display part 21. <P>COPYRIGHT: (C)2007,JPO&INPIT |
