Image sensing apparatus and image sensing method, X-ray photographing system and its control method

摘要

Since the duration of an idling drive period is not defined (not specified) in practical use, T 1 is set to be longer than that in a normal photographing operation to make idling-dedicated idle read frames Fi in which the ON time of a TFT ( 82 ) is shorter than the normal read drive frame, so as to minimize read operations that impose a heavy load on a photodetector array ( 58 ) (especially, the TFT ( 82 )).
