摘要： In a signal read circuit including a plurality of circuit rows each having a charge amplifier connected to a photoelectric conversion element PD and a CDS circuit 2S for performing correlated double sampling for an output from the charge amplifier, a dummy circuit row DMY having the same configuration as a circuit row SLT is connected in parallel with this circuit row SLT. By calculating the difference between these circuit rows connected in parallel, offset variations generated in the two circuit rows SLT and DMY can be removed.

摘要： A light chopper periodically transmits and blocks light, and first a dark current cancelling circuit determines an approximate mean value of the dark current from a photodiode when the light is blocked and cancels thus the mean value from the current signal fed into the integrated circuit, add to this, a differential arithmetic circuit that subtracts the remaining dark current component from the output of the integration circuit, thus the remaining signal indicates only the signal current component.

摘要： An amount of charges consonant with the intensity of the light entering photodiodes is generated, and the level of the charges is determined by a charge level determination circuit. Based on this determined charge level, a capacitance setting circuit sets a capacitance of an integrating capacitor unit in an integrating circuit. Thereafter, in the integrating circuit, the charges generated by the photodiodes are integrated in the integrating capacitor unit, and a voltage having a value consonant with the amount of the integrated charges is output. When background light is strong and the overall intensity of incident light is high, a comparatively large capacitance is set for the variable capacitor unit of the integrating circuit, and the intensity of the incident light is detected without saturation. When background light is weak and the overall intensity of incident light is low, a comparatively small capacitance is set for the variable capacitor unit of the integrating circuit, and the intensity of the incident light is detected at high sensitivity, regardless of the surrounding conditions.

摘要： In the solid-state imaging apparatus of the present invention, when a signal is output from the capacity element to the data signal output circuit, the voltage of the output terminal of the capacity element is kept at that attained when the switch was previously opened, namely, the initial voltage of the input terminal of the data signal output circuit, whereby the voltage of the input terminal of the data signal output circuit is stable without fluctuation. Therefore, no noise is generated in the output signal at the instant when the capacity element and data signal output circuit are short-circuited, whereby optical images can be captured with a high accuracy in a high speed.
