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.
