Radiation images with different resolutions may be captured using a general-purpose driver configured with a shift register group in a single system. Each shift register is connected to a first gate line or a second gate line via a connection terminal in accordance with wiring of a radiation detector. Under the control of an FPGA, in a case of low resolution imaging, a panel control section outputs OE signals that disable the output of on signals from the shift registers to the first gate lines in accordance with CPK signals. In a case of high resolution imaging, the panel control section outputs OE signals that disable the output of on signals from the shift registers to the second gate lines. In both cases, an on signal outputted from a shift register is inputted to a succeeding shift register.
