Abstract
Abstract A radiation image reproducing apparatus reads a radiation image out of a first recording medium and reproduces it on a second recording medium as a visible image. Input devices of the apparatus enter input data which are associated with a method of exposing an object to a radiation and object's exposed part. In response to the input data, a processing condition determining unit determines conditions optimum for a gradation processing and a spatial frequency processing. A processor system is provided for reading the radiation image stored in the first recording medium and processing the radiation image on the basis of conditions which the processing condition determining unit determines in response to the input data associated with the radiation image.
