A scheme for enabling proper radiation sensing to be performed without establishing
a synchronous connection by generating radioscopic and sensing timings of an image
sensor, includes a timing prediction unit for predicting an x-ray pulse timing
on the basis of a detection value of a first X-ray detection unit, and outputting
the predicted radiation pulse timing, and a drive control unit for effecting drive
control of a second X-ray detection unit on the basis of an output of the timing
prediction unit, thereby making it possible to perform the proper radiation sensing
without establishing the wired or wireless online synchronous connection.
