摘要： A color image-scanning device has a fixed scan mode and a flow scan mode. In the fixed scan mode, a document is scanned while maintaining the document at a fixed location on a platen glass. In the flow scan mode, a document is fed from an automatic document feeder and is scanned while moving the document. In each of these modes, images are scanned in a main scanning direction and a sub scanning direction. Color registration errors in the main and sub scanning direction caused by an optical factor are corrected in accordance with correction values stored in a memory. Respective correction values for each of the main and sub scanning directions are acquired by scanning a test chart in each of the fixed-scan mode and the flow-scan mode and stored in the memory. Proper correction values are read from the memory depending on the scanning mode selected, and color registration errors are corrected in accordance with the read correction value.
