An object of the present invention is to enable both high-speed reading of an image and acquisition of a high-definition image in a radiographic image capturing apparatus. A control means (22) of a radiation image capturing apparatus (1) applies an on-voltage to a plurality of adjacent scanning lines (5) at the same time by a scanning driving means (15) so that the number of binnings in the extending direction of a signal line (6) is reduced. Control is performed so as to acquire an image larger than the number of binnings in the extension direction of 5, and the acquired image is subjected to correction processing such as offset correction processing and transmitted to the console 58 by the communication unit 39. The control unit 58b of the console 58 performs enlargement interpolation processing on the extension direction of the signal line 6 of the image transmitted from the radiographic image capturing apparatus 1, and determines the pixel size in the extension direction of the signal line 6 by the extension of the scanning line 5. An image is generated according to the pixel size in the existing direction.
