Abstract
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.
