Title: IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Abstract:
An image processing device (100) calculates, using a plurality of images having different focusing positions, information of a distance to a subject, said image processing device (100) being provided with a frequency conversion unit (110), an amplitude extraction unit (120), and a distance information calculation unit (130). The frequency conversion unit (110) converts images into frequencies. The amplitude extraction unit (120) extracts an amplitude component from the phase component and the amplitude component of a coefficient obtained by the conversion into frequency. The distance information calculation unit (130) calculates distance information using defocus data of a lens, and merely the amplitude component thus extracted from the phase component and the amplitude component of the coefficient by means of the amplitude extraction unit (120).
