Abstract
An image signal is read by scanning a stimulable phosphor sheet on which radiation image information is recorded, with a stimulating light beam to cause the stimulable phosphor sheet to emit light representative of the recorded radiation image information, and photoelectrically detecting the emitted light. A change in the scanning speed at which the stimulable phosphor sheet is scanned with the stimulating light beam, is determined, and a corrective signal is determined based on the determined change in the scanning speed and a corrective coefficient established by at least reading conditions employed to read the radiation image information. The image signal is corrected with the corrective signal.
