Abstract
A radiation image capturing apparatus includes: scanning lines and signal lines; radiation detection elements; a scan driver switching a switching element of the radiation detection elements between on and off; and a readout IC incorporating readout circuits reading, as image data, electric charges from each radiation detection element, the readout circuit including: an integrating circuit outputting a voltage value corresponding to the electric charges; a reset switch resetting the integrating circuit; a first sample-and-hold circuit holding, as a reference value, the voltage value before the electric charges flow; a second sample-and-hold circuit holding, as a signal value, the voltage value after the electric charges flow; and a difference circuit outputting difference between the signal value and the reference value, the radiation image capturing apparatus further including a mechanism changing the voltage value from completion of the resetting and turning off of the reset switch until holding of the reference value.
