摘要: This invention has as its object to realize a radiation image sensing apparatus which can adjust (AEC-controls) the amount of incoming light or dose without requiring high-speed driving. Since a second photoelectric conversion element (108) which is used to detect the total dose of radiation that enters a conversion unit is formed independently of pixels having first conversion elements (101) that are formed in the conversion unit on a single substrate, the need for reading out the outputs from the first conversion elements (101) at high speed for the purpose of adjustment of the dose of incoming radiation can be obviated, and another sensor used to adjust the dose need not be added, thus simplifying the structure of a radiation image sensing apparatus.
