Patent ID: 7683337

Claim:
A radiographic apparatus comprising: a photoelectric conversion device array in which a plurality of pixels are arrayed on a substrate, wherein each of the pixels includes at least a photoelectric conversion device, and wherein said photoelectric conversion device can be initialized in a refresh operation and can generate a signal in each of photoelectric conversion operations, and the photoelectric conversion operations including at least a first photoelectric conversion operation and a second photoelectric conversion executed after the first photoelectric conversion operation; and a processor configured to determine whether to perform the refresh operation on the basis of image data acquired by the signals output from said photoelectric conversion device array in the first photoelectric conversion operation, wherein said processor does not perform the refresh operation between the first photoelectric conversion operation and the second photoelectric conversion operation when determining not to perform the refresh operation, and performs the refresh operation between the first photoelectric conversion operation and the second photoelectric conversion operation when determining to perform the refresh operation.
