Abstract
In an imaging system according to an embodiment, a camera unit and an information-processing unit are connected to each other by differential-signal transmission lines. The camera unit includes a solid-state imaging device and an output driver. The solid-state imaging device is configured to operate on the basis of a power source voltage higher than a substrate voltage and generate imaging data. The output driver is configured to output a differential signal of the imaging data to the differential-signal transmission lines. The information-processing unit includes a voltage generator and a de-emphasis circuit. The voltage generator is configured to generate a reference voltage higher than the substrate voltage and lower than the power source voltage. The de-emphasis circuit is configured to control an amplitude of the differential signal by using the substrate voltage and the reference voltage.
