Abstract

Image processing device is image processing device that uses a plurality of images respectively having focusing positions different from each other to calculate distance information to a subject, and includes frequency converter, amplitude extractor, and distance information calculator. Frequency converter converts the plurality of images into frequency. Amplitude extractor extracts an amplitude component out of a phase component and the amplitude component of a coefficient obtained by converting the plurality of images into frequency. Distance information calculator calculates the distance information, by using lens blur data and only the amplitude component extracted by amplitude extractor out of the phase component and the amplitude component of the coefficient.
