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.

摘要： In a signal processing device of an embodiment, an integration circuit accumulates a charge from a photodiode in an integrating capacitor element, and outputs a voltage value according to the amount of charge. A comparator circuit, when the voltage value from the integration circuit has reached a reference value, outputs a saturation signal. A charge injection circuit, in response to the saturation signal, injects an opposite polarity of charge into the integrating capacitor element. A counter circuit performs counting based on the saturation signal. A holding circuit holds the voltage value from the integration circuit. An amplifier circuit outputs a voltage value that is K times (where K>1) larger than the voltage value held by the holding circuit. An A/D converter circuit sets a voltage value that is K times larger than the reference value as the maximum input voltage value, that is, a full-scale value, and outputs a digital value corresponding to the voltage value from the amplifier circuit.
