Abstract:
1. An imaging apparatus comprising: a detection unit including a plurality of conversion elements arranged in an array on a substrate for converting incident radiation or incident light into an electric signal, to derive an image based on the electric signal; a memory unit for storing dark current response characteristics of the detection unit based on a time after applying a bias to the conversion elements; an accumulation charge quantity arithmetic operation unit for calculating a dark current accumulation charge quantity included in the accumulation, based on the dark current response characteristics, a first time period from an applying of a bias to the conversion elements until a start of an accumulation of the conversion elements for deriving the image and a second time period from a start of the accumulation until an end of the accumulation; and an image processing unit for conducting an offset correction of the image derived based on the dark current accumulation charge quantity.
