Disclosed herein is a radiation image information processing system basically comprising a plurality of image reading devices, a plurality of image recording devices and CRT displays which are respectively connected to the image reading devices, and a plurality of IDTs serving as registering means to which ID information of objects and other information are inputted. Further, the radiation image information processing system is characterized in that respective ones of the registering means, which are electrically connected to one another, are electrically connected to corresponding ones of the plurality of image reading devices, and other registering means are electrically connected to the respective ones of the registering means electrically connected to the corresponding ones of the plurality of image reading devices, the respective ones of the registering means electrically connected to the corresponding ones of the plurality of image reading devices having information control functions capable of storing therein information inputted to either the respective ones of the registering means or other registering means referred to above electrically connected thereto and of reading the so-stored information therefrom as needed.

Radiation image information processing system

A method of processing image or picture signals, including the steps of setting an n.times.n picture element matrix window (where n is an odd number) with respect to an image signal obtained by scanning an original picture; calculating a correction amount for pixel information at a center position of the window by a predetermined formula obtained on the basis of all of the pixel information within the window; subtracting pixel information of respective picture elements in the window by a suitable subtrahend; calculating the correction amount from added values obtained by adding all the pixel information within the window; converting the correction amount into a correcting value by multiplying the correction amount by a correction coefficient which also takes into consideration the effect of the subtraction on the correction amount; and correcting the pixel information by using the correcting value.

Method of processing image signal

A picture image input/output system which can obviate defects encountered in prior art systems is arranged such that plural original color pictures are enlarged or reduced at a predetermined magnification ratio respectively by a picture image scanning device and color separated to obtain color separation signals; such color separation signals are processed for appropriate color correction, sharpness enhancement and gradation conversion, and lay-out picture images are sequentially outputted on a recording material using lay-out instructions and information.
