摘要：
A signal processing system for processing output signals from an accumulating-type photoelectric transducer element is disclosed which has a squaring circuit and a threshold level control circuit which vary the threshold level of the output signals from the photoelectric transducer element at least at a part of a processing circuit, depending upon the ambient temperature and/or the intensity of light incident on the photoelectric transducer element, so that noise components included in the output signals from the photoelectric transducer element can be suppressed.
