<P>PROBLEM TO BE SOLVED: To correct an image blur and suppress image distortion in an imaging device equipped with an image sensor with an asynchronous accumulation period of a signal charge. <P>SOLUTION: An imaging device comprises: an image sensor in which a charge accumulation period is different for each predetermined area on an imaging surface; imaging control means that controls the drive of the image sensor to capture a subject in plural times of continuous exposure times; blur detection means that compares the plural captured images to detect a blur between the images; blur correction means that mutually shifts the plural images so as to correct the detected blur to combine them to one image; velocity vector calculation means that calculates a velocity vector of the subject based on the detected blur; and distortion correction means that corrects image distortion due to asynchrony of the charge accumulation period between the predetermined areas based on the velocity vector. <P>COPYRIGHT: (C)2012,JPO&INPIT |
