Abstract
An endoscope apparatus includes an endoscope including a cable and a sensor and a processor. The endoscope includes a differential amplifying section configured to differentially amplify an output signal from the sensor. The processor includes a power supply circuit configured to generate a reference voltage supplied to the differential amplifying section. The reference voltage generated by the power supply circuit of the processor is supplied to the differential amplifying section of the endoscope via the cable. An output signal of the differential amplifying section is detected by the processor via the cable.
