Patent ID: 8729484

Claim:
A radiographic imaging device comprising: an imaging panel at which a plurality of sensor portions, that detect radiation or light converted from radiation, are formed at a detection region, and that captures a radiographic image expressed by radiation or light converted from radiation, the detection region being divided into a plurality of sectional regions such that each sectional region is associated with more than one of the plurality of sensor portions; a light illuminating section at which a plurality of light-emitting portions, that can individually illuminate light for erasing residual images, are provided per sectional region; a storage section that stores imaging actual results information that expresses past actual results of imaging carried out by the imaging panel; a control section that controls, per sectional region, the light-emitting portion associated with said sectional region such that, in accordance with at least one of actual results of imaging, that are expressed by the imaging actual results information stored in the storage section, and imaging conditions, controls absence/presence of illumination of, light amount of, and illumination time period of light from the light-emitting portion; and an acquisition section that acquires a position of an imaging region within the detection region; wherein the control section controls the light illuminating section so as to cause light to be illuminated from the light-emitting portions that correspond to the imaging region acquired by the acquisition section; and wherein the control section causes at least some of the light-emitting portions that correspond to a non-imaging region to emit light at a light amount lower than a light amount of the light-emitting portions that correspond to the imaging region.
