ABSTRACT:
In a radiation image read-out method and apparatus, final read-out is carried out for obtaining image signals for use in reproduction of a visible image from a recording medium carrying a radiation image of an object recorded thereon, image processing conditions for use in processing of the final read-out signals obtained by the final read-out are adjusted, and image processing of the final read-out image signals is carried out by use of the image processing conditions. In the case where subdivision image recording is carried out by exposing each of a plurality of subdivisions on the recording medium to radiation in the course of the radiation image recording, image signals at a subdivision, which has not been exposed to the radiation, is removed from the final read-out image signals on the basis of information on subdivision image recording, and the image processing conditions are adjusted on the basis of the remainder of the final read-out image signals.
