摘要：

An image processing apparatus (10) for a radiation image obtains radiation image data obtained by radiation imaging using a radiation detector (11), and dark current data based on a signal obtained from the radiation detector without irradiating any radiation from a radiation generator (20). The image processing apparatus generates correction data by changing a ratio of frequency components based on the dark current data, and corrects the radiation image data based on the generated correction data.
