Abstract
An image reading method and apparatus for reading an image signal by exposure to reading light Lfrom a radiation solid-state detector, where radiation image information is recorded by exposure to recording light L, suppresses degradation of image quality such as the S/N ratio of a reproduced image, the degradation being caused by an effect of charges which are produced by exposure to excessive radiation or the like and remains in the radiation solid-state detector. In the image reading method and apparatus, a past image signal read regarding past image information recorded in the radiation solid-state detector in the past, and an elapsed time from a time of recording the past image information in the radiation solid-state detector to a time of recording the current radiation image information are stored. The current image signal is then corrected based on the recorded past image information and the elapsed time.
