Abstract:
A method of obtaining an image signal, comprising the steps of:preparing an image recording sheet having a stimulable phosphor layer which emits photostimulated luminescent light in a quantity corresponding to stored energy when irradiated with stimulating light; scanning said image recording sheet in horizontal and vertical scanning directions with said stimulating light; and obtaining said image signal by detecting said photostimulated luminescent light emitted by the scanning, with a solid-state image detector having a photoconductor; wherein a signal, output from said solid-state image detector when scanning a non-image region other than an image recording region on said image recording sheet with said stimulating light, is detected as a correction signal; and a non-image component, contained in a signal output from said solid-state image detector when scanning said image recording region with said stimulating light, is suppressed with said correction signal.
