PROBLEM TO BE SOLVED: To generate an excellent signal any without noise in ordinary imaging. SOLUTION: A column noise detection section 31 detects a column noise value in an effective image region A in a state of the region A being shielded by a shutter 11, a column noise change detection section 33 detects a column noise change amount in a HOPB region B in real time, a column noise correction value generating section 34 corrects the column noise value detected by the column noise detection section 31 on the basis of the column noise change amount detected by the column noise change detection section 33 and generates a column noise correction value, and a column noise correction section 35 corrects a signal S4 supplied from the effective image region A in the ordinary image photographing on the basis of the column noise correction value.
