Apparatus, method, and program for processing image

An image processing apparatus includes a correction parameter calculation unit for calculating a motion blur correction parameter for motion blur correction on the basis of motion information indicating a motion of an image between unit images, the unit images forming image data, and shutter speed information obtained at the image capturing of the image data, and a motion blur correction processing unit for correcting a motion blur quantity contained in the image data by performing at least a process of reducing a motion blur in accordance with the motion blur correction parameter.
