ABSTRACT:
This invention provides a signal processing circuit of a solid-state imaging device utilizing discontinuous scanning pulses having fixed interval times, and with a fixed pattern noise-eliminating circuit of high performance. In the signal processing circuit of this invention, switching elements are disposed in a feedback circuit of a signal amplifier (for example, pre-amplifier) and at an output of the signal amplifier, whereby the fixed pattern noise is suppressed so as to attain a high signal-to-noise ratio.
