摘要：
All of reference data are stored into a memory of a device main body and the reference data according to a condition at that time is written into a reference data memory built in an image processing IC of a scanner cartridge. By correcting an image signal by using the reference data, an image can be read at a high quality without increasing a memory capacity in the cartridge.
