ABSTRACT:
In a signal processing circuit for use in a solid-state camera having a solid-state image sensor for converting picture elements composing an optical image to electrical signals. The circuit comprises a sensor for sequentially sensing the electrical signals representing the picture elements output of the solid-state image sensor, a converter for converting the output signal of the sensor into a first and a second signal which are respectively in phase with and opposite phase to the output signal of the sensor, first and second integrators for integrating the first and second signals for each picture element respectively, and a differential amplifier for producing an output signal representing a difference between two outputs of the first and second integrator as a video signal.
