ABSTRACT:
There is provided a photoelectric converting apparatus which is constructed in a manner such that a control electrode of a Darlington type transistor is electrically connected to a signal output side of photoelectric conversion elements which can accumulate photoelectrically converted charges, load means is electrically connected to one main electrode of the Darlington type transistor, an emitter-follower circuit is constructed, and a signal is read out from the main electrode and that the photoelectric converting element is constructed so as to accumulate the photoelectrically converted charges into a control electrode region of a semiconductor transistor and to take out an amplified signal from one main electrode region of the semiconductor transistor. In one arrangement, an offset signal is generated and subtracted from the accumulated charge signal to eliminate noise.
