PROBLEM TO BE SOLVED: To solve a problem of a conventional solid-state image pickup device, whose pixel is configured with one photodiode, 4 transistors(TRs) and one capacitor, that cannot have utilized only either of a field shutter function and a kTC (k is Boltzman's constant, T is absolute temperature and C is a capacitance) noise cancel function. SOLUTION: After resetting a capacitor Ce by a TR M1, a charge transfer TR M5 is conductive to transfer charges obtained by photoelectric conversion at a photo diode PD to the capacitor Ce, where the charges are stored. Then each TR M5 is turned off simultaneously for all the pixels and Trs M1, M3 of pixels on the same row are conductive, to provide a prescribed level to a CDS(correlation dual sampling) circuit 5. Succeedingly, a TR M6 is conductive and the TR M3 is turned on to output a signal corresponding to the charges, by a field shutter function stored in the capacitor Ce to the CDS circuit 5. Thus, the CDS circuit transfer can cancel kTC noise.
