Document Type and Number:
WIPO Patent Application WO/2020/066231
Kind Code:
A1
Abstract:
This radiographic imaging device for capturing a radiographic image using a detection unit having disposed, in a pixel region thereof, a plurality of imaging pixels having sensitivity to radiation and a plurality of light-shielding pixels having no sensitivity to radiation, is provided with: an image acquisition unit which acquires an offset correction image while no radiation is being delivered; a difference acquisition unit which acquires differences in pixel values of the light-shielding pixels between the offset correction image and a radiographic image acquired as a result of irradiation with radiation; and a correction unit which corrects the offset correction image on the basis of a distribution of offset signals, of the light-shielding pixels in the pixel region, acquired using the differences.
