    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.
