1. An image processing apparatus comprising: an input section, configured to input a plurality of image capturing data time-divisionally exposed by a capturing unit; a divider, configured to divide the plurality of image capturing data into synthesis images or motion detection images; a detector, configured to detect a motion amount of the capturing unit at the time of time-division exposure from the image capturing data of the motion detection images; a synthesizer, configured to generate synthesized image capturing data by synthesizing the synthesis images; and a corrector, configured to correct a vibration of the synthesized image capturing data based on a divide pattern indicating divisions by said divider, and the motion amount.
