ABSTRACT:
A first image signal representing a radiation image is detected from a stimulable phosphor sheet, on which the radiation image has been stored, its probability density function is created, and a characteristic value of the probability density function is detected. Values of differences between the characteristic value and values of the first image signal in the probability density function are calculated. Information representing the values of the differences is fed into a neural network, and information representing temporary read-out conditions and/or temporary image processing conditions is fed out from the neural network. The temporary read-out conditions and/or the temporary image processing conditions are corrected in accordance with the level of the characteristic value. Read-out conditions, under which a second image signal representing the radiation image is to be obtained from the stimulable phosphor sheet, and/or image processing conditions, under which the second image signal having been obtained is to be image processed, are thereby adjusted.
