Abstract
A radiation imaging apparatus including an accumulation unit to accumulate electrical charge in accordance with radiation for each pixel circuit of a plurality of pixel circuits. An output unit outputs an analog signal for each pixel circuit by sampling and holding an electrical signal in accordance with a voltage of an accumulation unit for each pixel circuit. The output unit stops the output during a reset operation of the accumulation unit. A selection unit selects pixel circuits that output the analog signals. The selection unit stops the selection during a reset operation of the accumulation unit. A determination unit determines whether a total time of an exposure time and an output time required to output the analog signals corresponding to all the pixel circuits is longer than an imaging interval that is based on a synchronization signal representing a radiation generation timing input from an external apparatus.
