摘要： To eliminate a residual image due to residual charge in an image sensor circuit and provide an effective bright-time output, the image sensor is provided with a reset switch connected to a photodiode. After the potential of the photodiode is held through a first amplifier in two holding circuits as an image signal and an initial signal, the initial signal and the image signal are sequentially output through a second amplifier. By resetting the photodiode to a desired potential to produce an initial signal, a residual image can be eliminated.

摘要： A light receiving element is provided with a phototransistor and a light receiving MOS diode proximate thereto and having a gate electrode covering a portion of the base region of the phototransistor. The gate electrode permits transmission of a portion of received light. The light receiving MOS diode forms an inversion layer in a substrate adjacent the base of a phototransistor during the time photo charges are stored, and generated photo charges are stored in the inversion region and the base region of the phototransistor. During the storage state, the potential of the inversion region and the base region of the phototransistor is limited, so that the intensity of an electric field applied to an insulating film between the electrode and the semiconductor substrate is 0.7 MV/cm or less. Alternatively, the potential of the electrode in a waiting state is fixed or made floating, so that an electric field is not applied, and recombination at the surface of the semiconductor substrate is made stable.

摘要： A voltage at an output terminal of a photodiode is reset to a fixed voltage and an output signal of the photodiode and a dummy signal matching a dark output signal is output by a dummy photodiode comprising an identical component as that of the photodiode. The voltage difference between an input side and an output side of an amplifier is made to match the difference between a reset voltage of the photodiode and a reset voltage of a common signal line and a reset voltage of an output terminal to optimize the size of a MOS transistor forming the amplifier. The offset voltage is set to a constant which does not depend on the size of the MOS transistor. The amplifier is formed with CMOS devices and is selectively operated only during an output operation to suppress the current consumption.
