Abstract:
1. A radiographic imaging system comprising: a detector including a plurality of pixels each having a conversion element configured to convert radiation or light into electric charge, the detector being configured to output image data corresponding to irradiated radiation or light, the detector having a first area where irradiation occurs in a first radiation field, and a second area other than the first area where irradiation occurs in a second radiation field larger than the first radiation field; and an image processing unit configured to perform image processing on the image data, wherein the image processing unit includes a storage unit configured to store dark output information that is based on an integral dose of the radiation or light and dark output characteristics of the pixels, a measurement unit configured to measure a first integral dose and a second integral dose, the first integral dose being an integral dose of radiation or light with which a first pixel included in the first area is irradiated, the second integral dose being an integral dose of radiation or light with which a second pixel included in the second area is irradiated, and a correction unit configured to correct, based on the dark output information obtained from the storage unit and the first integral dose and second integral dose measured by the measurement unit, at least one of data of the first pixel and data of the second pixel within the image data when switching from the first radiation field to the second radiation field has occurred.
