Photoelectric transducer and solid-state image pickup device

摘要

A photoelectric transducer provided with a first photoelectric converting section for generating an electric charge according to incident light, an accumulating section for accumulating the electric charge generated by the first photoelectric converting section, an amplifying section for amplifying the electric charge outputted from the accumulating section with a prescribed gain, and a storage section for memorizing signal charges amplified by the amplifying section, characterized in that the prescribed gain in the amplifying section is altered in 1 field/1 frame period on the basis of the number of electric charges accumulated in the accumulating section during a prescribed period before the application of the gain.
