ABSTRACT:
A radiographic system is provided, which is capable of displaying brightness of laterally corresponding points with equivalent brightness, when an object having equivalent texture structures or micro areas of equivalent X-ray transmittance at laterally symmetric positions. The radiographic system includes an exposure time deriving section that obtains a period during which the object has been exposed to X-rays in a process of generating each charge signal output from an X-ray image detecting section based on vertical transfer information held at the vertical transfer information holding section, a correction coefficient deriving section that obtains a correction coefficient for correcting the value of an image signal obtained by being converted from each charge signal, based on the exposure time, and an image generating section that generates an image signal from the charge signal output from the X-ray image detecting section and the correction coefficient.
