ABSTRACT:
A method for detecting artifact signal components comprises the steps of detecting an image signal made up of a series of image signal components representing a radiation image from a recording medium on which the radiation image has been recorded. Specific image signal components, which have values smaller than a predetermined threshold value, are detected from the image signal. Investigation is made to find how many neighboring picture elements the specific image signal components correspond to. In cases where the number of the neighboring picture elements is smaller than a predetermined number, it is determined that the specific image signal components are artifact signal components.
