Abstract

A foreshortening calculating unit of an image processing device calculates the degree of foreshortening in an imaging range at the time of synthetic aperture radar imaging using a flying object on the basis of an orbit at the time of the synthetic aperture radar imaging and elevation data of the earth's surface. A polygon calculating unit calculates a polygon representing an actual outer boundary of the imaging range by calculating an outer boundary of an actual imaging range of the imaging range using the degree of foreshortening. An area determining unit determines, by using the polygon, which of two or more areas determined in an area imaged by the synthetic aperture radar the imaging range belongs to. An added value adding unit performs a process which is performed according to the determined area on an image of the imaging range on the basis of a determination result of the area to which the imaging range belongs from the area determining unit.
