<p>PROBLEM TO BE SOLVED: To provide a radiographic device in which, even in the case where an offset pattern is acquired beforehand, an artifact is prevented from appearing and noise is reduced further, a control method thereof and a program.SOLUTION: It is determined whether an image captured from an imaging region is an offset pattern image for correcting an offset value of a pixel value acquired from a pixel constituting the imaging region or an effective image being irradiated with radiation. When it is determined that the image captured from the imaging region is the offset pattern image as a result of the determination, first correction data based on a pixel value acquired from a light shielding region provided in a part of the imaging region are generated. The first correction data are stored in a first memory. When it is determined that the image captured from the imaging region is the effective image as a result of the determination, second correction data based on a pixel value acquired from the light shielding region are generated. The first correction data and the second correction data are used to correct an artifact generated in the effective image.</p> |
