Abstract: In order to reduce crosstalk caused between control signal wires in a semiconductor apparatus without increasing the size of the semiconductor apparatus, a noise guard circuit is provided at the opposite end of the control signal wire to the driver circuit. The noise guard circuit controls in such a way as to increase the impedance between the relevant control signal wire and a fixed potential when the logic of the relevant control signal wire is positive logic for driving the element, and as to decrease the impedance between the relevant control signal wire and a fixed potential when the logic of the relevant control signal wire is negative logic for driving the element.

Abstract: A second source follower circuit of a reference voltage generator includes a transistor having the same characteristics as a first source follower circuit of a pixel. Accordingly, the second source follower circuit can generate a second reference voltage according to the change in characteristics of the first source follower circuit. A noise voltage switching circuit outputs a first voltage as a noise voltage to a pixel signal generator when the noise voltage is equal to or lower than the second reference voltage. In a reset state, the noise voltage and the second reference voltage always have a predetermined voltage difference. Therefore, deterioration in image quality can be prevented even when capturing a subject having high brightness. Since a trimming circuit or the like selecting any one of a plurality of reference voltages according to characteristics of a formed transistor becomes unnecessary, the cost of an imaging device can be reduced.

Abstract: A circuit for correction of white pixel defects capable of complementing white pixel faults without using a storage device for holding white pixel fault spots, and an image sensor using the circuit for correction of white pixel defects. Pixels constituting a pixel section are sequentially subjected to white pixel fault complementation process. A nearby pixel data holding section acquires pixel data from a readout circuit and holds the data. A comparison-determination section compares lightness of a target pixel with that of a nearby pixel and determines, based on the comparison result, whether or not the target pixel is associated with a white pixel fault having a lightness higher than that of the nearby pixel by a predetermined value or more. When it is judged by the comparison-determination section that the target pixel is associated with a white pixel fault, a complementary calculation section performs a complementary calculation by using the pixel data of the target and nearby pixels held by the nearby pixel data holding section, to generate complemented data.

Abstract: A differential amplifier has a first input terminal to which a voltage of a noise signal of the solid-state imaging device is supplied and a second input terminal to which a voltage of a temporary data signal having the noise signal of the solid-state imaging device superposed thereon is supplied. The differential amplifier inverts an output signal when a magnitude relationship in voltage between the first and second input terminals becomes reverse. A measurement circuit measures a variation amount of a voltage of the second input terminal from when the voltage of the second input terminal begins to vary in a direction to reverse the magnitude relationship to when the output signal of the differential amplifier is inverted, and outputs a measurement result as a digital value indicating a voltage of a real data signal obtained by removing the noise signal from the temporary data signal.
