PROBLEM TO BE SOLVED: To perform higher-precision optical correction when an optical system is driven during a charge storage period. SOLUTION: An imaging apparatus has a control module 10 for performing charge storage of an imaging module while driving an optical system; a storage module 7 which has stored therein optical characteristics of the optical system for a plurality of optical parameters; an acquisition module for acquiring optical parameters at a plurality of times while the optical system is driven; a calculation module for calculating optical parameters at starting and ending times of a charge storage period; a readout module for reading optical characteristics corresponding to the optical parameters from the storage module; a combination module for weighting and combining the plurality of optical characteristics read out in accordance with a length between the times at which the optical parameters are acquired; a correction module 9 for correcting an image signal for each pixel; and a generation module 8 for generating an optical correcting value corresponding to an image height of the pixel to be corrected from the weighted and combined optical characteristics. The correction module 9 corrects the image signal using the optical correction value generated by the generation module 8. COPYRIGHT: (C)2011,JPO&INPIT
