ABSTRACT:
An image processing method is intended to extract an irradiation area in an image easily and accurately.A calculation unit202calculates secondary difference values of density values representing respective areas in three areas of a rectangular shape arranged in parallel on an image, determined by a calculation area input unit200and a calculation area determination unit201, between adjacent rectangular areas and the secondary difference values thus calculated are stored in a memory unit203. Then a judgment unit204judges one end point of an irradiation area from the secondary difference values thus stored and an irradiation area determination unit205determines the irradiation area, based on a plurality of end points thus judged.
