CCD solid-state image pick-up device, analog signal processing system and analog signal processing method

摘要

In a CCD solid-state image pick-up device according to the present invention, a solid-state image pick-up circuit formed by a sensor part, a horizontal transfer register part and a floating diffusion amplifier converts a photo signal into a voltage signal and outputs the voltage signal, and a voltage-current conversion circuit converts the voltage signal output from the solid-state image pick-up circuit into a current signal. A current-driven black signal component detect/remove circuit then removes a black signal component from the current signal output from the CCD solid-state image pick-up device, and an image signal component alone is output as a current image signal. A current-voltage conversion circuit converts the current image signal into a voltage image signal.
