Abstract
A solid state image pickup device is composed of basic cells each of which comprises a photodiode one terminal of which is grounded, a n-MOS transistor whose gate is connected to the other terminal of the photodiode and whose source is grounded and furthermore whose drain is connected to a load, a feedback capacitor and switching element for resetting both of which are connected between the drain and gate of the n-MOS transistor. As an advantage of such a configuration, the reduction of the sensitivity due to the junction capacitance of the photodiode can be suppressed, and furthermore accurate signal output voltages can be obtained even in the case where the amount of incident light changes during an integration period.
