Abnormalities of multiple sensors with redundancy are detected with higher accuracy. A semiconductor device according to the present invention includes: a plurality of internal sensors that detect an identical object to be detected; a switching circuit that switches detection signals from the internal sensors at a predetermined frequency and outputs the signals; a correction information extracting circuit that extracts a first frequency component for correcting the output signal of a predetermined external sensor, from a converted signal based on an output of the switching circuit; and an abnormality information extracting circuit that extracts a second frequency component for detecting abnormalities of the internal sensors, from the converted signal based on the output of the switching circuit.
