RADIATION IMAGE READ-OUT METHOD AND APPARATUS ABSTRACT OF THE DISCLOSURE A stimulable phosphor sheet carrying a radiation image stored therein is scanned with stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the radiation energy stored therein. The emitted light is photoelectrically detected to obtain sequential electric signals of respective picture elements of the radiation image. The interference among the electric signals of the respective picture elements which is caused by the light emission response characteristics of the stimulable phosphor to the stimulation is eliminated electrically. The correction is conducted by adding a differentiated value of the sequential electric signals of the respective picture elements to the sequential electric signal of the respective picture elements.
