Abstract
A motion detecting part detects moving regions in a plurality of frame images captured by rolling shutter type exposure, and obtains a motion vector of the moving regions. A moving region correcting part corrects the moving region in a to-be-corrected frame image of the plurality of frame images on the basis of the motion vector, information on an image-capturing time interval between the plurality of frame images, information on an exposure starting time difference resulting from the difference in position in one frame image caused by the rolling shutter type exposure and information on an exposure start sequence depending on the position in one frame image captured by the rolling shutter type exposure.
