ABSTRACT:
An image pickup signal processing apparatus includes an A/D converter and a nonlinear signal processing circuit for comparing an image pickup signal input to the A/D converter and a voltage obtained by dividing a reference voltage of the A/D converter and nonlinearly processing the image pickup signal. The nonlinear signal processing circuit includes a negative feedback amplifier and circuit components for changing the amount of negative feedback provided by the negative feedback amplifier to generate nonlinear characteristics.
