Abstract: A detection device includes a plurality of optical sensors arranged in a detection area, a light source configured to emit light that is emitted to an object to be detected and is detected by the optical sensors, and a processor configured to perform processing based on outputs from the optical sensors. The processor is configured to determine, based on the outputs of the respective optical sensors obtained at a cycle of a predetermined period, an optical sensor an output of which is to be employed from among the optical sensors.
