ABSTRACT:
A solid state image pickup device with built-in signal amplifier produces an image signal from an output potential signal produced from each charge packet by a charge converting unit, and the built-in signal amplifier includes a sampling-and-hold circuit connected between the charge converting unit and a signal amplifying circuit for changing a potential signal from a reset field-through potential level to a signal potential level, thereby eliminating a reset field-through noise from an input potential signal supplied to the signal amplifier.
