Abstract
A radiation image pickup apparatus which selectively executes a first reading operation driving a detection unit irradiated with the radiation to read a first signal value, a second reading operation driving the detection unit without being irradiated with any radiations before the first reading operation to read a second signal value, and a third reading operation driving the detection unit without being irradiated with any radiations after the first reading operation to read a third signal value, and subtracts a signal value produced by the processing of the second signal value and the third signal value from the first signal value, thereby reducing an offset component and random noises without lowering a frame rate and its control method are provided.
