ABSTRACT:
The present invention relates to a sensor apparatus having a structure capable of obtaining digital values of signal components with a high accuracy using an A/D conversing circuit with the outputted digital value thereof having a small number of expressive bits. In the sensor apparatus, a voltage value corresponding to the amount of incident light to a photodiode is held by a holding circuit through an integrating circuit and a CDS circuit. Meanwhile, a voltage value corresponding to the amount of incident light to an adjacent photodiode is held by another holding circuit through an integrating circuit and a CDS circuit. The voltage values held by the respective different holding circuits are inputted to a subtracting circuit through different paths. The subtracting circuit outputs a voltage value corresponding to the difference between the two inputted voltage values. In an A/D converting section, the difference voltage outputted from the subtracting circuit is converted into a digital value.
