摘要： Sensitivity is freely changeable to another one in correspondence to a photographing mode, and both still image photographing and moving image photographing for example which are largely different from each other in dosage of exposure to radiation and which are also different from each other in required sensitivity are carried out so as to meet that request. A source or drain electrode of a TFT 21 is connected to a signal output circuit 3 through a signal line 14a and an IC 5. A source/drain of a TFT 23 is connected to the signal output circuit 3 through a signal line 14b and the IC 5. Thus, in each pixel 6, any one of the signal lines 14a and 14b is freely selectable when a signal is read out.

The detection unit acquires a first signal value representing a current flowing to the first bias line when the switch element of a pixel in pixels whose conversion elements are connected to the first bias power supply unit in the plurality of pixels is in a conduction state, and a second signal value representing a current flowing to the second bias line when the switch element of a pixel whose conversion element is connected to the second bias power supply unit in the plurality of pixels is in a non-conduction state such that sampling timings at least partially overlap, and determines the presence/absence of radiation irradiation based on the first signal value and the second signal value.
