摘要： A scanning device or alight beam is moved for reciprocal scanning with respect to an image carrier, which carries image information thereon, and in a main scanning direction. The scanning device or the light beam is also moved with respect to the image carrier and in a sub-scanning direction intersecting with the main scanning direction. Light, which comes from the image carrier, is photoelectrically converted into an electric image signal. Smoothing operation processing is performed on forward scanning image signal components and backward scanning image signal components, which have been acquired respectively in a forward scanning stage and a backward scanning stage consecutive in the reciprocal scanning, and with respect to the sub-scanning direction.

摘要： With an optical head, a stimulating ray beam produced by a stimulating ray source is irradiated onto an image carrier supported on a stage, and light emitted by the image carrier is collected and guided toward a photodetector. At least either one of the optical head and the stage is moved with respect to the other and in two-dimensional directions along a plane parallel with the other. The optical head comprises a concave mirror for reflecting the stimulating ray beam, which travels in parallel with the stage, toward the image carrier, and a lens for converging the stimulating ray beam, which has been reflected from the concave mirror, onto the image carrier. The lens and the concave mirror also guide the light, which is emitted by the image carrier, toward the photodetector.
