Abstract

PURPOSE:To obtain an apparatus which is driven by low voltage and is scarcely influenced by deterioration of S/N, by integrating at every picture element the sum of a current proportional to the input voltage, and a current having the opposite polarity to said current. CONSTITUTION:The current source 93 is connected to the capacity Cc which is used for integration, and an average current of the current which is flowing in the collector and emitter of the transistor 64 is made to flow into the capacity Cc from the current source 93. As a result, the sum of the first current proportional to the input voltage applied to the base of the transistor 64, and the second current having the opposite polarity to the first current is stored in the capacitor Cc, and it is led out to the output terminal 69 through the switch 65.
