摘要:
Each pixel is provided with a photoelectric converting device S1(1-1) or the like, a source-follower-type first transistor T1(1-1) or the like, a second transistor Te(1-1) to be turned on when reading an electrical signal from a pixel selected by a shift register SR1 for each line and outputting the signal to a readout circuit unit and a third transistor T3(1-1) to be turned on when resetting a photoelectric converting device set to a pixel selected by a shift register SR1 for each line. Moreover, a bias power source for supplying a photoelectric conversion bias to a photoelectric converting device and a reset power source for supplying a reset bias to a photoelectric converting device are set in the readout circuit unit. By using the radiation image pickup apparatus and its control method, it is possible to improve the S/N ratio while restraining noises and preferably, it is possible to perform stable and high-speed dynamic-image photographing and restrain dark current.
