Abstract
A detection device includes: a detection circuit which carries out detection processing of a physical quantity on the basis of a signal from a physical quantity transducer and outputs detected data of the physical quantity; and a correction unit which carries out correction processing on the detected data and outputs the data after the correction processing as output data. The correction unit carries out the correction processing to reduce an integration error generated in the case where the output data is subjected to integration processing, on the detected data of m bits, and outputs the output data of n bits (n and m being natural numbers, holding n<m).

A detection device comprising:
- a detection circuit which carries out detection processing of a physical quantity on the basis of a signal from a physical quantity transducer and outputs detected data of the physical quantity;
- and
- a correction unit which carries out correction processing on the detected data and outputs the data after the correction processing as output data;
- wherein the correction unit carries out the correction processing to reduce an integration error generated in the case where the output data is subjected to integration processing, on the detected data of m bits, and outputs the output data of n bits (n and m being natural numbers, holding n<m),
- wherein the correction unit carries out integration processing of an error in the output data with respect to the detected data and carries out the correction processing on the basis of an integration result value of the integration processing.
