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.
