IMAGING DEVICE, DRIVING METHOD THEREOF, RADIATION IMAGER USING THE ELEMENT, AND RADIATION IMAGING SYSTEM USING THE DEVICE

摘要

PROBLEM TO BE SOLVED: To enable high speed high sensitivity moving image photographing and wide dynamic range low noise still image photographing by using one imaging device. SOLUTION: A plurality of picture elements are provided which comprise; a photodiode PD for converting optical energy to an electric signal; MOS transistors M6, M7 which are connected with the photodiode PD and in which the electric signal outputted from the photodiode PD is inputted; and a MOS transistor M3 arranged between the photodiode PD and the MOS transistor M7 or a MOS transistor M2 and the MOS transistor M3 which are arranged between the photodiode PD and the MOS transistor M6 and between the photodiode PD and the MOS transistor M7, respectively.
