Abstract
An apparatus for processing radiographic image signals, including a photographing device for detecting an amount of radioactive rays transmitted through a subject and for converting the rays into original digital image signals in the form of pixels, and a signal processing circuit for processing the original digital image signals so as to decrease the amplitude of a low frequency component of the original digital image signals.
