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.

摘要： An imaging apparatus includes a control unit and a detector that includes multiple pixels and that performs an image capturing operation to output image data corresponding to emitted radiation or light. The image capturing operation includes a first image capturing operation in which the detector is scanned 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 which the detector is scanned 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 initialization operation to initialize the conversion element during a period between the first image capturing operation and the second image capturing operation in accordance with switching from the first scanning area to the second scanning area.
