There is described a radiation image reading apparatus, which includes a semiconductor detector for converting radiation photons penetrated through a subject into electric signals to generate a first radiation image information and a processor for processing the first radiation image information, so that a modulation transfer function in a low density region is not higher than a modulation transfer function in a high density region, in order to generate a second radiation image information. The abovementioned semiconductor detector includes a substrate, a plurality of electrodes, capacitors, switching elements, a photoconductive layer and a surface electrode, which are fabricated on the substrate. |
