<p>PROBLEM TO BE SOLVED: To accelerate a signal read action of a radiation imaging apparatus which detects radiation rays with a plurality of sensitivities.SOLUTION: The radiation imaging apparatus comprises: a sensor array in which a plurality of sensors for detecting radiation rays with first and second sensitivities are arrayed; a row selection part for selecting a sensor array for each row; a signal read part for reading signals from the sensors of the row selected by the row selection part; and a control part. Each of the plurality of sensors includes first and second holding parts. The control part performs first control for controlling the sensor array so as to hold first and second signals captured with the first and second sensitivities in the first and second holding parts, and second control for controlling the row selection part so as to read the first and second signals from the sensors for each row by the signal reading part. In the second control, after the first and second signals held in the first and second holding parts for the sensors of a row being selected by the row selection part are read by the signal reading part, the row selection part selects the sensors of the next row.</p> |
