The present invention is to allow an XY-address scanning-type imaging device such as a CMOS imaging device to detect a fluorescent flicker correctly and accurately and reduce a fluorescent flicker component surely and sufficiently. The RGB primary color signals arising from A/D conversion of the RGB primary color signals obtained from an imaging element are clamped. Subsequently, for the clamped RGB primary color signals, the following processes are executed: correction of the gains of reading-out channels; reduction of fixed pattern noise; correction of the data of defective pixels; noise reduction; lens shading correction; and gain adjustment for exposure adjustment. Thereafter, for the resultant signals, a flicker detection and reduction unit 60 detects and reduces a flicker component. Furthermore, white balance adjustment is implemented for the RGB primary color signals for which the flicker has been reduced, and then defective pixels in the imaging element are detected from the RGB primary color signals for which the white balance adjustment has been executed.
