Abstract:
A photoelectric transducer comprising:a first photoelectric converting section for generating an electric charge according to incident light, an accumulating section for accumulating electric charges generated by said first photoelectric converting section, an amplifying section for amplifying the electric charge outputted from said accumulating section with a prescribed gain, and a storage section for storing signal charges amplified by the amplifying section during a 1 field/1 frame period, wherein; the 1 field/1 frame period being separated into a plurality of subperiods, and said prescribed gain in the amplifying section varies during the 1 field/1 frame period, the prescribed gain having an initial value during a first subperiod of the 1 field/1 frame period and a value during other subperiods determined on the basis of the number of electric charges stored in said storage section during a preceding portion of the 1 field/1 frame period.
