Abstract
A radiation image capturing apparatus includes scan lines, signal lines, radiation detection elements, bias lines, a readout IC, a control unit and a noise detection unit. The detection elements generate electric charges by receiving radiation. The readout IC reads respective image data based on the respective electric charges. The control unit controls at least the readout IC. At the time when each image data is read, the detection unit outputs data based on voltage noise in reverse bias voltage applied to the detection elements via the bias lines and/or voltage noise in off voltage applied to the scan lines. The control unit estimates an offset component in the output data, calculates noise data based on the output data and the offset component and subtracts the noise data from the image data, thereby generating corrected image data.
