PROBLEM TO BE SOLVED: To enable all radiographic images to be output while attaining radiation imaging at a high frame rate.SOLUTION: There is provided a radiation imaging apparatus which includes: a synchronization signal detection part for detecting a synchronization signal; an imaging request signal detection part for detecting an imaging request signal showing that it is in a series of imaging periods at imaging intervals corresponding to the synchronization signal; an accumulation part for converting radiation ray radiated at an imaging interval to an electronic signal and accumulates it; and an output part for sample-holding an electric signal and outputting as an analog signal for each pixel circuit. When a frame rate based on an imaging interval exceeds a reference value, the output part outputs a prescribed number of pixels among pixel circuits, thereafter temporarily stops outputting, and when after the temporary stoppage of outputting, an imaging request signal is not detected, it resumes output as to remaining pixel circuits. |
