Abstract: A radiation image capturing apparatus includes, as a plurality of pixels two-dimensionally arranged in an image capturing area, a plurality of image pixels configured to output electric signals for acquiring a radiation image and a plurality of detection pixels configured to output electric signals for detecting information about irradiation of the image capturing area with the irradiation. The plurality of detection pixels is arranged as a line-shaped detection pixel group in the image capturing area, and a plurality of detection driving lines is connected to the line-shaped detection pixel group. A readout circuit reads out, at different timings, the electric signals group by group to each of which a different one of the plurality of detection driving lines is connected in the line-shaped detection pixel group.

Abstract: A radiation imaging system includes pixel array, scanning circuit to scan rows of the pixel array, and readout circuit to read signals from the pixel array. Each pixel includes converter to generate electric signal corresponding to radiation and transistor connected to the converter. The readout circuit reads signal from the converter via the transistor. The system performs image capturing modes and conditioning mode of conditioning a threshold voltage of the transistor. In the conditioning mode, the scanning circuit supplies, to a gate of the transistor, an OFF voltage different from OFF voltages in the image capturing modes. The scanning circuit scans the rows in units of at least one row in the image capturing modes, and scans the rows in units of at least two rows in the conditioning mode.
