摘要： A radiation imaging apparatus is capable of taking a moving picture by acquisition by a reading circuit of a plurality of radiation image signals on the basis of a plurality of successive times of irradiation of a radiation detector with radiation rays. The radiation detector has a two-dimensional array of pixels. In a period between a start of an n-th time of irradiation with radiation rays and a start of an (n+1)-th time of irradiation with radiation rays, where n is a natural number, a controller switches an operation status of an analog-to-digital converter that converts electric signals read by the reading circuit into digital signals so that power consumption of the analog-to-digital converter is reduced.

摘要： The invention intends to be able to adequately perform a gain correction. Hence, at the time of radiographing an object, a gain correction of the object image is performed based on a gain correction image (XRc1) derived by performing a light reset. On the other hand, at the time of radiographing an object, when a light reset is not performed, a gain correction of the object image is performed based on a gain correction image (XRc2) derived without performing the light reset.

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.

摘要： An idling time period after applying a bias to a conversion element until a start of an accumulation of the conversion element for deriving an image and an accumulation period from the start of the accumulation to a termination of the accumulation are measured. An offset correction of the image is conducted by using a dark current accumulation charge quantity in the accumulation calculated based on the measured idling time period and accumulation period and stored dark current response characteristics. Thus, even just after applying the bias to the conversion element, the offset correction can be properly conducted. An imaging apparatus which can execute a good radiographing without increasing costs and a size even just after applying the bias to the conversion element is provided.
