摘要： An imaging apparatus includes a detector in which a plurality of pixels are arranged in a matrix; each pixel includes a conversion element that converts radiation or light into an electric charge. The detector performs an exposure imaging operation for outputting exposure image data, a correction imaging operation for outputting correction image data, and a correction imaging preparation operation including an initialization operation for initializing the conversion element between the exposure imaging operation and the correction imaging operation. A correction unit corrects the exposure image data using the correction image data; and a control unit controls the operation of the detector so that the detector performs the initialization operation based on an amount of variation in offset of the conversion element at the time of transitioning from an exposure imaging preparation operation to the exposure imaging operation.

The image capturing operation includes a first image capturing operation in a first scanning area corresponding to part of the multiple pixels to output image data in the first scanning area and a second image capturing operation in a second scanning area larger than the first scanning area to output image data in the second scanning area. The control unit causes the detector to perform an accumulation operation in the second image capturing operation in a time determined so that an image artifact caused by the scanning area is lower than a predetermined allowable value on the basis of information about the amount of integration of accumulation times in the first image capturing operation.
