Abstract
In a radiation image recording and reproducing system, an image signal obtained by forming a radiation image by a radiation passing through an object and photoelectrically detecting the radiation image is subjected to frequency processing by use of a predetermined degree of enhancement. The degree of enhancement is corrected in accordance with the radiation exposure dose so that the degree of enhancement is decreased as the exposure dose decreases, thereby improving the image quality of a reproduced visible image.
