Abstract:
1. A radiographic image detecting device comprising: an image detector having an imaging area having a matrix of a plurality of pixels each for accumulating signal charge in accordance with an irradiation amount of radiation emitted from a radiation source, for detecting a radiographic image by receiving said radiation passed through an object; a plurality of radiation detectors disposed in said imaging area, each for outputting a detection signal in accordance with said irradiation amount of said radiation; and a control unit for performing a synchronization control for synchronizing an operation of said image detector with emission start timing of said radiation based on said detection signal of said radiation detector, and an automatic exposure control for controlling a total irradiation amount of said radiation based on said detection signal of said radiation detector, wherein said detection signal of said radiation detector disposed in a first detection area in said imaging area is used in said synchronization control, and said detection signal of said radiation detector disposed in a second detection area smaller than said first detection area is used in said automatic exposure control.
