PROBLEM TO BE SOLVED: To generate objective AGC data to be different from each product or each optical system and to obtain objective image data with a simple method. SOLUTION: A correction coefficient K1 is multiplied with a reference white board peak level and AGC data are decided by the peak level. A different correction coefficient is used for reading of a reference white board at shading correction and for original reading respectively and different AGC data are fed back. A correction coefficient K2 to generate AGC data exclusive use for each optical system is calculated. |
