Claim 2:
3. The detection apparatus according to claim 1, wherein
the optical sensor is configured to perform detection using the photoelectric conversion elements in each of a plurality of detection periods provided in a time-division manner,
during a first detection period, the lighting device emits the first light using the first light-emitting elements, and the wavelength selection filter is in a transmitting state for a wavelength region including the first maximum emission wavelength,
during a second detection period, the lighting device emits the second light using the second light-emitting elements, and the wavelength selection filter is in the transmitting state for a wavelength region including the second maximum emission wavelength, and
each of the photoelectric conversion elements outputs a signal based on the first light to a detection circuit during the first detection period and outputs a signal based on the second light to the detection circuit during the second detection period.
