ABSTRACT:
In a image processing system, a cassette loading unit, a reciprocating feed system, an auxiliary scanning feed mechanism, and an erasing unit are controlled by a first CPU, and an image reading process and error processes relative to the reading of image information are performed by a second CPU. The image processing system starts a shading correcting process at a time when a first time has elapsed from a time when a start-of-scan signal is supplied, and ends the shading correcting process and detects an error and an erasing level at a time when a third time has elapsed from a time when an effecting reading period is ended.
