Abstract:
1. An imaging system comprising: an imaging apparatus including a detector in which a plurality of pixels each including a conversion element that converts radiation or light into an electric charge are arranged in a matrix form and which performs an image capturing operation to output image data corresponding to radiation or light that is emitted, and a control unit that controls operations including the image capturing operation of the detector; and a control computer configured to control the imaging apparatus, wherein the image capturing operation includes a first image capturing operation and a second image capturing operation, the first image capturing operation including a first accumulation operation in which the conversion element generates the electric charge and a first output operation in which the detector is scanned in a first scanning area corresponding to part of the plurality of pixels to output image data in the first scanning area, the second image capturing operation including a second accumulation operation in which the conversion element generates the electric charge and a second output 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, wherein, if switching from the first scanning area to the second scanning area is performed, the control computer performs arithmetic processing 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 and supplies a control signal based on the time of the second accumulation operation determined in the arithmetic processing to the control unit, and wherein the control unit controls the operation of the detector so that the second accumulation operation is performed in the time of the second accumulation operation determined in the arithmetic processing.
